Detailed ways

Figure 1 shows the control schematic diagram of an intelligent dust removal device composed of a smoke and dust sensing device, a controller, a dust removal device and a data display unit. The smoke and dust sensing device is connected to the controller, and the controller is connected to the dust removal device through a drive port and a feedback port. The controller is also connected with a data display unit. The dust sensing device detects the pollution degree of the air in the factory building, and sends the real-time data of the detected smoke to the controller for comparison with the set value. The controller automatically starts or closes the corresponding dust removal fan according to the comparison value, or outputs a variable signal Control the speed of the fan for the frequency converter.

The dust removal device shown in Figure 2 is composed of a dust removal fan 1, a dust removal main air duct 3, a plurality of dust removal branch air ducts 4, a fan frequency converter 2, and a controller 7. The dust removal main air passage 3 is connected to the dust removal fan 1 air inlet 8, and a plurality of dust removal branch air passages 4 are connected to the dust removal main air passage 3, and an electric control valve 5 is respectively set in each dust removal branch air passage 3, and the electric control valve 5 is linked with the corresponding dedusted equipment, controlled by the working state of the dedusted equipment, when the dedusted equipment is working, the electronically controlled valve 5 is opened, and when the dedusted equipment is stopped, the electronically controlled valve 5 is closed. A wind pressure sensor 6 is arranged in the dust removal main air passage 3, and is arranged near the air inlet of the dust removal fan 1. The wind pressure sensor 6 sends the collected wind pressure signal to the controller 7 in real time, and the controller 7 sends the wind pressure sensor 6 The wind pressure signal collected is compared with the set value preset in the controller 7, and a variable signal is output to the fan inverter 2 according to the comparison value, and the fan inverter 2 controls the speed of the dust removal fan 1.

Figure 3 shows the control flow chart of the intelligent dust removal equipment. According to the linkage between the electronically controlled valve and the dedusted equipment, it is judged whether there is any equipment shutdown. When the dedusted equipment is working, the electronically controlled valve is opened, and when the dedusted equipment is stopped, the electronically controlled valve is closed. When one or more dust removal devices in the dust removal system stop working, the corresponding electric control valves are closed, the wind pressure sensor detects wind pressure fluctuations, and the controller outputs frequency up or down frequency signals to the fan inverter according to the wind pressure changes. , so as to control the fan speed. When no equipment in the dust removal system stops working, the wind pressure detected by the wind pressure sensor does not fluctuate. At this time, according to the real-time detection data of the smoke sensor device and the set value in the controller, when the set value is greater than the detection data, There is no need to turn on the dust removal fan; when the set value is less than the detection data, the controller sends a signal to turn on the dust removal fan to automatically turn on the fan, and sends a frequency up or down signal to the fan inverter according to the change of smoke and dust, and the frequency converter adjusts the fan speed rise or fall.

The electronically controlled valve 5 includes an actuator and a valve, and the actuator controls the opening or closing of the valve.
