Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise indicated, the terms "first," "second," and the like are used to distinguish one element from another without sequence or importance. Furthermore, in the following description, when referring to the drawings, the same reference numerals in different drawings denote the same or similar elements unless otherwise explained. The foregoing definitions are provided for the purpose of illustrating and explaining the present disclosure and should not be construed as limiting the present disclosure.

According to a specific embodiment of the present disclosure, referring to fig. 1, there is provided a boiler oil supply system including an oil reservoir 100, a boiler system 200, a variable frequency pump 300, and an oil supply line 400 for supplying oil to circulate and communicate the oil reservoir 100 and the boiler system 200, the variable frequency pump 300 being disposed on the oil supply line 400 for pumping oil to the oil supply line 400, the boiler oil supply system further comprising: a communication pipe 500, the communication pipe 500 communicating with the oil supply pipe 400, and one end of the communication pipe 500 being disposed upstream of the boiler system 200 and the other end being disposed downstream of the boiler system 200; the pressure stabilizing pump 510, the pressure stabilizing pump 510 is arranged on the communication pipeline 500; and a first control door 410, the first control door 410 being provided on the oil supply line 400 for selectively communicating or intercepting the oil reservoir 100 with the boiler system 200.

Through the above technical scheme, in the boiler oil supply system provided by the present disclosure, after the boiler oil supply system is put into use, fuel oil can enter the oil supply pipeline 400 from the outlet of the oil reservoir 100 under the pumping action of the variable frequency pump 300, and circulate into the boiler system 200 and the communication pipeline 500 through the oil supply pipeline 400, and then flow back to the inlet of the oil reservoir 100 through the oil supply pipeline 400 to supply the fuel oil for the boiler system 200. After the boiler system 200 stably operates, the boiler system 200 does not continue to consume fuel, at this time, the fuel supply pipeline 400 and the communication pipeline 500 are filled with fuel, the oil depot 100 is disconnected from the boiler system 200 through the first control door 410, and meanwhile, the variable frequency pump 300 is operated to be closed and the steady pressure pump 510 is operated to be opened, so that fuel can circulate in the communication pipeline 500, the boiler system 200 and the fuel supply pipeline 400 between the communication pipeline 500 and the boiler system 200, and the path length of one circle of fuel circulation can be shortened, so as to achieve the purpose of saving power consumption.

In the boiler oil supply system provided by the present disclosure, the first control gates 410 may be disposed at any suitable position, and as an exemplary embodiment, referring to fig. 1, the number of the first control gates 410 may be two, and the two first control gates 410 may be located upstream of the communication pipe 500 and downstream of the communication pipe 500, respectively. In this way, the first control door 410 can control the on-off between the oil depot 100 and the boiler system 200, but at the same time, the on-off of the communication pipeline 500 and the boiler system 200 is not affected. After the boiler system 200 is stably operated, both the first control doors 410 are simultaneously closed to ensure that neither fuel is flowing out of the reservoir 100 nor fuel is flowing in. The communication line 500, the boiler system 200, and the oil supply line 400 between the communication line 500 and the boiler system 200 may together constitute a circulation line in which fuel is circulated when the two first control doors 410 are simultaneously closed, so that the fuel in the circulation line may be introduced into the boiler system 200 when the boiler system 200 needs to use the fuel to prevent the boiler system 200 from extinguishing a fire.

In the boiler fuel supply system provided by the present disclosure, as an exemplary embodiment, referring to fig. 1, the boiler fuel supply system may further include an accumulator 600, the accumulator 600 may communicate with the fuel supply line 400, and the accumulator 600 may be disposed near the boiler system 200 and upstream of the boiler system 200 for storing fuel or supplying fuel to the fuel supply line 400. When the oil reservoir 100 is in communication with the boiler system 200, the fuel in the fuel supply line 400 enters the accumulator 600 to be stored; when the first control door 410 is closed, the oil reservoir 100 cannot continue to supply fuel to the boiler system 200. At this time, if the sudden oil consumption occurs in the boiler system 200, the accumulator 600 may be used to supply the boiler system 200 with the fuel, so that the first control door 410 and the variable frequency pump 300 do not need to be frequently opened and closed, which can further save the electricity consumption and prolong the service lives of the first control door 410 and the variable frequency pump 300.

In another embodiment, the accumulator 600 may also be connected to the oil supply line 400, and the accumulator 600 may be disposed near the boiler system 200 and downstream of the boiler system 200, and in other embodiments, the accumulator 600 may be disposed at other suitable locations, so long as the accumulator 600 is capable of providing fuel to the circulation line, for example, the accumulator 600 may be connected to the connection line 500, which is not particularly limited in this disclosure.

In the boiler oil supply system provided by the present disclosure, in order to realize automatic switching of the circulation line and the oil supply line 400, as an exemplary embodiment, the boiler oil supply system may include a control device, an inductor may be provided inside the accumulator 600, the inductor may be used to sense liquid level information of fuel, the first control door 410 may be configured as an electric door, the control device may be electrically connected with the inductor and the first control door 410, respectively, and the control device may be used to control opening and closing of the first control door 410 according to the liquid level information. In this way, when the fuel amount in the accumulator 600 decreases below the position where the sensor is located (i.e., when the fuel amount in the accumulator 600 is insufficient), the control device can control the first control door 410 to open, so that the oil reservoir 100 supplies oil to the boiler system 200, ensuring that the boiler system 200 can stably operate, and avoiding fire extinguishment of the boiler system 200.

In the boiler oil supply system provided in the present disclosure, in order to ensure stable operation of the boiler oil supply system, as an exemplary embodiment, referring to fig. 1, the boiler oil supply system may further include an oil supply pump 420 and an auxiliary variable frequency pump 460, and the oil supply pump 420 and the auxiliary variable frequency pump 460 may be both disposed on the oil supply line 400 and arranged in parallel with the variable frequency pump 300. In this way, the oil supply pump 420 and the auxiliary variable frequency pump 460 can both be used as backup pumps for the variable frequency pump 300, and when the variable frequency pump 300 fails or needs to be overhauled, the auxiliary variable frequency pump 460 can be used for pumping fuel into the oil supply pipeline 400; when both variable frequency pump 300 and auxiliary variable frequency pump 460 fail or require service, fuel can be pumped into fuel supply line 400 by fuel supply pump 420 to ensure that the pan fuel supply system is operating stably.

In the boiler oil supply system provided in the present disclosure, in order to facilitate maintenance or replacement of the oil supply pump 420, the auxiliary variable frequency pump 460, and the variable frequency pump 300, as an exemplary embodiment, referring to fig. 1, the boiler oil supply system may further include a second control gate 430 and a third control gate 440, and the oil supply pump 420, the auxiliary variable frequency pump 460, and the variable frequency pump 300 may be provided with the second control gate 430 and the third control gate 440, respectively, upstream and downstream of the oil supply line 400. In this way, when the oil feed pump 420, the auxiliary variable frequency pump 460 or the variable frequency pump 300 fails, the fuel in the oil feed line 400 can be prevented from entering the oil feed pump 420, the auxiliary variable frequency pump 460 or the variable frequency pump 300 by closing the corresponding second control gate 430, so as not to cause damage; when the oil supply pump 420, the auxiliary variable frequency pump 460 or the variable frequency pump 300 can be used normally, the corresponding second control gate 430 is kept in an open state; the opening and closing of the third control gate 440 can control whether the corresponding oil feed pump 420, auxiliary variable frequency pump 460 and variable frequency pump 300 are put into use, and in addition, the second control gate 430 and the third control gate 440 can be simultaneously closed to isolate the corresponding oil feed pump 420, auxiliary variable frequency pump 460 or variable frequency pump 300 separately for replacement.

The second control door 430 may be configured as a manual door, and the third control door 440 may be configured as an electric door. In this way, the electric door can respond faster when it is necessary to switch between the feed pump 420, the auxiliary variable frequency pump 460, or the variable frequency pump 300. In other embodiments, the second control gate 430 may be an electric gate, and the third control gate 440 may be a manual gate, which is not particularly limited in this disclosure.

In the boiler fuel supply system provided in the present disclosure, in order to prevent the reverse flow of the fuel, as an exemplary embodiment, referring to fig. 1, the boiler fuel supply system may further include a check valve 450, and the check valve 450 may be provided downstream of the fuel supply pump 420, downstream of the auxiliary variable frequency pump 460, and downstream of the variable frequency pump 300, respectively. In this way, the fuel in the fuel supply line 400 can flow only in one direction, i.e., in the direction from the outlet of the reservoir 100 to the inlet of the reservoir 100, so that not only can the stable operation of the boiler fuel supply system be ensured, but also the fuel can be prevented from flowing back into the fuel supply pump 420, the auxiliary variable frequency pump 460 or the variable frequency pump 300.

In the boiler oil supply system provided in the present disclosure, as an exemplary embodiment, referring to fig. 1, the boiler oil supply system may further include a fourth control door 520, and the fourth control door 520 may be provided on the communication pipe 500 to selectively communicate or intercept the communication pipe 500 with the oil supply pipe 400. Thus, when the communication line 500 needs to be put into use, the fourth control door 520 may be opened, otherwise the fourth control door 520 may be closed.

Wherein the number of fourth control gates 520 is two, and the two fourth control gates 520 may be disposed upstream and downstream of the regulated pump 510, respectively. In this way, two fourth control gates 520 may be utilized to isolate the regulated pump 510 individually to facilitate servicing and replacement of the regulated pump 510.

In the boiler oil supply system provided in the present disclosure, as an exemplary embodiment, referring to fig. 1, the boiler system 200 includes at least one boiler 210, each boiler 210 including a bypass pipe 220, both ends of the bypass pipe 220 communicating upstream and downstream of the corresponding boiler 210, respectively, for selectively conducting or intercepting the boiler 210 and the oil supply line 400. In this way, the bypass pipe 220 can isolate the corresponding boiler 210, and when the boiler 210 does not need oil or the boiler 210 has a problem and needs maintenance, the bypass pipe 220 can be used to prevent the fuel oil from flowing through the corresponding boiler 210, and meanwhile, the normal oil supply of the boiler oil supply system to other boilers 210 is not affected.

In summary, when the boiler oil supply system provided by the present disclosure is used, the first control door 410 is operated to open first, so that the oil supply pipeline 400 is communicated with the oil reservoir 100 and the boiler system 200, after the energy accumulator 600, the communication pipeline 500 and the oil supply pipeline 400 are filled with fuel oil and the boiler system 200 is stably operated, the first control door 410 is operated to close, if the boiler system 200 suddenly needs to use the fuel oil in the process, the circulation pipeline and the energy accumulator 600 are preferably utilized to provide the fuel oil for the boiler system 200 until the fuel oil in the energy accumulator 600 is insufficient, the first control door 410 is operated to open, so that the oil reservoir 100 provides the fuel oil for the boiler system 200.
