Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

With the development of modern industry, the impact of dust on the environment and human health is becoming more and more serious. It has become the consensus of the Chinese people to control dust pollution and purify the living environment of human beings.

The equipment that separates dust from flue gas is called dust collector or dust removal equipment. The performance of the dust collector is expressed in terms of the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life and difficulty of operation and management of the dust collector are also important factors to consider its performance. There are many types of dust collectors, including plastic sintered plate dust collectors, pulse bag dust collectors, etc. Among them, pulse bag dust collectors have the advantages of high adaptability, high dust collection efficiency, reasonable structure, and significant energy saving effect.

Dust collectors are widely used in grain transportation and processing enterprises; dust collection systems such as crushing, packaging, storage roofs, clinker coolers and various mills in cement plants, as well as waste gas collection in metallurgy, chemical industry, machinery and civil boilers. dust. However, the existing dust collector is prone to block the filter bag during the dust removal process, which reduces the dust removal effect of the dust collector. Generally, in order to prevent the filter bag in the dust collector from being blocked by dust, the filter bag in the dust collector will be cleaned regularly. However, since some dust collectors (such as plug-in type dust collectors) have the same opening for dust suction and ash outlet, when the dust collector sprays the positive pressure airflow for cleaning the filter bag, the dust collector in the dust collector The negative pressure airflow generated for vacuuming is still working, and the positive pressure airflow and the negative pressure airflow cancel each other out, so that the positive pressure airflow cannot remove the dust on the filter bag, that is, the cleaning rate of the filter bag in the dust collector. lower.

Based on the above analysis, the embodiment of the present application provides a dust collector 10 and a dust removal system, wherein a first valve 132 is provided in the dust collection module 130 of the dust collector 10. When the dust collector 10 is working normally to remove dust, the first valve 132 can be opened. Valve 132, so that the dust can be sucked out of the body 110 of the dust collector 10 from the first valve 132 by the airflow to be dedusted generated by the fan 131; Closing the first valve 132, because the fan 131 can no longer generate the airflow to be dedusted, the backflushing and cleaning module 140 can blow off the dust on the filter bag 120 in the dust collector 10, and the cleaning module 140 generates dust The airflow will not be offset by the airflow to be dedusted generated by the fan 131 , thereby improving the cleaning rate of the filter bag 120 in the precipitator 10 .

The precipitator 10 provided by the embodiments of the present application will be described in detail below.

Please refer to FIG. 1 . FIG. 1 is a structural block diagram of a dust collector according to an embodiment of the application. The dust collector 10 may include: a body 110 , a filter bag 120 , a dust suction module 130 , a backflushing dust removal module 140 and a control module 150. The filter bag 120 is arranged in the body 110; the dust collection module 130 is arranged in the body 110, and the dust collection module 130 includes a fan 131 and a first valve 132, and the first valve 132 is arranged on one side of the fan 131; The ash module 140 is arranged on one side of the filter bag 120 ; the control module 150 is connected to the dust suction module 130 and the backflushing ash cleaning module 140 . When the first valve 132 is opened, the air to be dedusted will be sucked out of the body 110 from the first valve 132 by the fan 131 after being dedusted by the filter bag 120 ; when the first valve 132 is closed, the backflushing and cleaning module 140 will clean the filter bag 120 Ash.

For example, the dust collector 10 provided in the embodiment of the present application may include a body 110, and the body 110 is equivalent to an air chamber of the dust collector 10, in which the nozzle 141 and the filter bag 120 of the dust collector 10 are wrapped to separate them. Dust airflow, cleaning airflow, protection of components, and moisture and water resistance.

It can be understood that, because the dust collector 10 needs to inhale the airflow to be dedusted carrying the dust flying in the air, and then filter the airflow to be dedusted to obtain a dust mass and a clean airflow, and then discharge the clean airflow out of the dust collector 10 and return through the dust. The collected dust mass is returned to the conveying line and mixed with the material. Therefore, the body 110 of the dust collector 10 may be provided with two openings, one opening is used to inhale the airflow to be dedusted (named as the first opening), and the other opening is used to discharge the clean airflow obtained after filtering the airflow to be dedusted (named the first opening). for the second opening). Wherein, the embodiment of the present application does not specifically limit the position, shape and size of the opening on the body 110, and those skilled in the art can make appropriate adjustments according to the actual situation.

It should be noted that the embodiments of the present application also do not specifically limit the shape and material of the body 110 , and those skilled in the art can adopt a body 110 of suitable shape and material in combination with conventional technical means in the art.

One or more filter bags 120 may be provided in the above-mentioned body 110. The function of the filter bags 120 is to filter the airflow to be dedusted sucked into the dust collector 10 to remove the dust therein. The airflow to be dedusted filtered by the filter bag 120 can be regarded as two parts, the clean airflow and the dust mass. The dust mass can be returned to the conveying line to save raw materials; the clean air flow can be discharged from the dust collector 10 and returned to the outside air to realize the dust removal of the outside air.

It should be noted that the embodiments of the present application do not specifically limit the quantity, type, shape, arrangement, etc. of the filter bags 120 , and those skilled in the art can use suitable filter bags 120 in combination with conventional technical means in the field.

In the above description, the airflow to be dedusted can be sucked into the dust collector 10 , and then the clean airflow obtained after the airflow to be dedusted can be discharged out of the dust collector 10 . As an embodiment, the dust collection module 130 may include a fan 131 and a first valve 132 . The fan 131 can be arranged outside the body 110 of the dust collector 10, and is located at the second opening that discharges the clean air flow obtained after filtering the air flow to be dedusted, and is used to suck the air flow to be dedusted into the dust collector 10 and filter the air to be dedusted. The airflow is sucked out of the body 110 of the dust collector 10 through the second opening. The first valve 132 can also be arranged at the second opening, that is, it can be arranged between the fan 131 and the second opening (fan 131-first valve 132-second opening), or the first valve 132-fan 131- The order of arrangement of the second openings is not specifically limited in this embodiment of the present application. As an embodiment, the first valve 132 may be a pneumatic valve, a valve driven by compressed air.

When the first valve 132 is opened, the fan 131 can suck the airflow to be dedusted into the dust collector 10, and suck the clean airflow out of the body 110 of the dust collector 10 through the second opening; when the first valve 132 is closed, the fan 131 cannot draw the airflow to be dedusted. The dust removal airflow is sucked into the dust collector 10 and the clean airflow is sucked out from the body 110 of the dust collector 10 through the second opening.

After the above-mentioned dust collector 10 has been used for a period of time, a large amount of dust is deposited on the filter bag 120 disposed inside the body 110 , which affects the normal dust removal of the dust collector 10 . Therefore, the filter bag 120 can be cleaned. At this time, it is the backflushing and cleaning module 140 in the dust collector 10 that performs the process. The backflushing ash cleaning module 140 can generate a ash cleaning airflow to blow off the ash accumulated on the filter bag 120, and also form a dust mass to return to the material conveying line. Wherein, if the backflushing and cleaning module 140 and the dust collecting module 130 work at the same time, the air flow for cleaning dust and the air flow to be dedusted will cancel each other, so that the effect of cleaning the filter bag 120 is greatly reduced. The cleaned ash is sucked onto the filter bag 120 before being mixed with the material. Therefore, there is a problem that the cleaning rate of the filter bag 120 in the dust collector 10 is low.

Therefore, when the backflushing and cleaning module 140 is in operation, the operation of the dust collecting module 130 can be stopped by closing the first valve 132 . After the first valve 132 is closed, the fan 131 cannot generate the airflow from the first opening to the second opening inside the dust collector 10. Therefore, there is only a dust cleaning airflow inside the dust collector 10 that can clean the filter bag 120. The dust-cleaning airflow can effectively remove the dust on the filter bag 120, and can also avoid the opportunity of cleaning to return to the filter bag 120 again. That is, by closing the first valve 132 when the backflushing and cleaning module 140 is working, the cleaning rate of the filter bag 120 in the dust collector 10 can be improved.

It can be understood that the first valve 132 does not have to be closed every time the backflushing and cleaning module 140 works. Can be closed.

As an embodiment, please refer to FIG. 2 , which is a structural block diagram of another dust collector provided in the embodiment of the application. In the dust collector 10 , the backflushing and cleaning module 140 may include a nozzle 141 and a second dust collector 141 . valve 142. Wherein, the nozzle 141 may be arranged in the body 110 of the dust collector 10, and one or more air outlet holes may be arranged on the nozzle 141, and each air hole is directed toward the corresponding filter bag 120 for ejecting the dust-cleaning airflow to the filter bag 120. Wherein, the embodiments of the present application do not specifically limit the positions and sizes of the air holes, and those skilled in the art can make appropriate adjustments according to the actual situation. For example, one air hole corresponds to one filter bag 120, and each air hole is arranged at equal intervals.

The second valve 142 may be disposed at one end of the nozzle 141. As an embodiment, the second valve 142 may be a pulse solenoid valve. Among them, the realization principle of the pulse solenoid valve is as follows: the pulse signal is input to the coil in the pulse solenoid valve body through the wire, and the pulse solenoid valve is controlled by the output signal of the pulse injection controller, depending on the pressure change of the two air chambers before and after the valve, so that the rubber The flexural deformation of the diaphragm realizes the opening and closing of the pulse solenoid valve. The number of the second valves 142 is not specifically limited in the embodiment of the present application, and it may be one second valve 142, or multiple second valves 142, or the number of the second valves 142 and the filter bag 120. corresponding quantity. When the number of the second valves 142 is opposite to the number of the filter bags 120 , by controlling the opening and closing of the different second valves 142 , the backflushing cleaning module 140 can clean the different filter bags 120 respectively.

When the second valve 142 is opened, the nozzle 141 can spray the dust-cleaning airflow onto the filter bag 120, so that the dust-cleaning airflow blows off the integral on the filter bag 120, so as to achieve the effect of cleaning the filter bag 120; When the second valve 142 is closed, the nozzle 141 cannot spray the dust-cleaning airflow onto the filter bag 120 . In combination with the first valve 132 in the above-mentioned embodiment, when the first valve 132 is closed and the second valve 142 is opened, there is only a dust-cleaning airflow inside the dust collector 10 that can clean the filter bag 120, and the dust-cleaning airflow can The dust accumulation on the filter bag 120 can be removed efficiently, and the opportunity of cleaning can also be avoided to return to the filter bag 120 again.

It can be understood that the second valve 142 can be opened when the filter bag 120 needs to be cleaned by the backflush cleaning module 140, or it can be opened periodically. It only needs to be ensured that the cleaning module 130 stops once within a certain period of time. The second valve 142 may be in an open state during operation.

Therefore, the dust collecting module 130 of the dust collector 10 is provided with a first valve 132. When the dust collector 10 is working normally to remove dust, the first valve 132 can be opened, so that the clean air flow obtained after the dust removal air flow can be filtered by the fan 131. The first valve 132 sucks out the body 110 of the dust collector 10; when the backflushing and cleaning module 140 in the dust collector 10 wants to clean the filter bag 120, the first valve 132 can be closed. A second valve 142 is provided in the backflushing and cleaning module 140 of the dust collector 10. When the backflushing and cleaning module 140 in the dust collector 10 wants to clean the filter bag 120, the second valve 142 can be opened to make the dust The dust cleaning airflow generated by the nozzle 141 can be blown off the filter bag 120; when the dust collector 10 is working normally to remove dust, the second valve 142 can be closed. When the first valve 132 is closed and the second valve 142 is opened, since the fan 131 can no longer suck the clean air out of the dust collector 10, the backflushing dust cleaning module 140 can blow off the dust on the filter bag 120 in the dust collector 10, and The cleaning airflow generated by the backflushing and cleaning module 140 will not be offset by the cleaning airflow sucked out by the fan 131 , thereby improving the cleaning rate of the filter bag 120 in the dust collector 10 .

In addition, the dust collector 10 provided in this embodiment of the present application may further include a control module 150, the control module 150 is connected to the dust collection module 130 and the backflushing cleaning module 140, and controls the dust collection module 130 to perform dust removal and backflushing cleaning respectively. The ash module 140 cleans the filter bag 120 . It can be understood that when the dust collection module 130 includes the first valve 132, the control module 150 can be connected to the first valve 132 to control the opening and closing of the first valve 132; when the first valve 132 is a pneumatic valve, the control module 150 is connected to the coil of the pneumatic valve. Similarly, when the backflushing and cleaning module 140 includes the second valve 142, the control module 150 can be connected to the second valve 142 to control the opening and closing of the second valve 142; when the second valve 142 is a pulse solenoid valve, control the The module 150 is connected to the coil of the pulse solenoid valve.

As an embodiment, the process that the control module 150 controls the dust collection module 130 to perform dust removal and the backflushing dust removal module 140 to perform dust removal to the filter bag 120 can be manually controlled by the operator. For example: when it is necessary to start the dust collector 10 for dust removal, the operator can input corresponding commands to the control module 150 to turn on the fan 131, and the control module 150 outputs a control command to open the first valve 132 and close the second valve 142; When the bag 120 is being cleaned, the operator can input a corresponding command to the control module 150 again, and the control module 150 outputs a control command to open the second valve 142 and close the first valve 132 .

It can be understood that the above-mentioned process manually controlled by the operator is only an example provided by the embodiment of the present application, and those skilled in the art can make appropriate adjustments according to the actual situation, so as to realize the dust removal of the air and the removal of the filter bags in the dust collector 10 . 120 for cleaning.

As another embodiment, the process that the control module 150 controls the dust collection module 130 to perform dust removal and the backflushing dust removal module 140 to perform dust removal to the filter bag 120 can be controlled by an existing program. In this case, please refer to FIG. The module 150 may further include a single-chip controller, and the single-chip controller is connected to the dust collection module 130 and the backflushing and cleaning module 140 . Wherein, those skilled in the art can implement the function of the control module 150 on the above-mentioned single-chip controller in combination with common knowledge. The following describes in detail a control process that can realize the dust removal of the dust collection module 130 and the control of the dust removal of the filter bag 120 by the backflushing dust cleaning module 140 .

In the embodiment of the present application, each second valve 142 may be opened in turn according to a preset time interval, and in order to reduce the frequency of actions of the first valve 132, the method of closing the first valve 132 at intervals is used in the embodiment of the present application deal with. That is, the first valve 132 is not closed and all the second valves 142 are not opened every time the backflushing is performed. Due to the limited amount of compressed air generated, the second valve 142 can be opened in turn to generate the dust cleaning airflow. Each time one filter bag 120 is backflushed to clear dust, all filter bags 120 are backflushed once for one cycle.

As an embodiment, in each cycle, the first valve 132 is only closed when about one third of the filter bags 120 are backflushed, and the first valve 132 is not closed when the remaining filter bags 120 are backflushed.
