The sensors monitor the dust concentration in the areas in real time and transmit data in the form of electric signals to the master controller 6, which is used to adjust the water flow in each area bin 401 according to the dust concentration.

[0038] The master controller 6 receives data from the dust concentration sensors and sends control signals to the pressure regulating pump 207 controller, the air valve controller 306 and the on-off electromagnetic valve 7. For example, when the dust concentration in a certain area is high, the master controller 6 controls the pressure regulating pump 207 in the water supply branch pipe 204 corresponding to the area to increase the water pressure, increases the opening of the water flow valve 206 and increases the water flow; at the same time, the master controller 6 controls the air valve controller 306 in the air supply branch pipe 303 to increase the opening of the air flow valve 305, increases the air pressure and increases the air flow, so as to increase the spray intensity and the spray amount in the area. Conversely, when the dust concentration in a certain area is low, the water flow and the air flow are reduced correspondingly.

[0039] Referring to Figure 2 , the water pipe 203 and the air pipe 302 are provided with on-off electromagnetic valves 7, the water pipe 203 comprises a plurality of water supply branch pipes 204, the air pipe 302 comprises a plurality of air supply branch pipes 303, and the water supply branch pipes 204 and the air supply branch pipes 303 are respectively communicated with the area bins 401.

[0040] Referring to Figure 3 , the area bin 401 comprises a gas-liquid mixing chamber 403, an air inlet chamber 404 is communicated with an inlet end of the gas-liquid mixing chamber 403, a water inlet jet pipe 405 is connected with an end of the air inlet chamber 404, a conical nozzle 406 is formed at an end of the water inlet jet pipe 405, the conical nozzle 406 extends into the air inlet chamber 404, the gas-liquid mixing chamber 403 forms a Laval tube structure, and the gas-liquid mixing chamber 403 is connected with the spray pipe 101 through the water-air branch pipe 402.

[0041] Each area warehouse 401 is provided with a gas-liquid mixing chamber 403, the inlet end of the gas-liquid mixing chamber 403 is communicated with the air inlet chamber 404, the end of the air inlet chamber 404 is connected with the water inlet jet pipe 405, the tapered nozzle 406 at the end of the jet pipe 405 extends into the air inlet chamber 404, the water and air are fully mixed in the gas-liquid mixing chamber 403, the gas-liquid mixing chamber 403 forms a Laval tube structure, which can further optimize the gas-liquid mixing effect and form a fine water-in-air form, and at the same time accelerate the water flow, and is connected to the spray pipe 101 through the water-air branch pipe 402.

[0042] The water pressure sensor 205, the water flow valve 206 and the pressure regulating pump 207 are arranged on the water passage branch pipe 204, and the pressure regulating pump 207 is connected with a pressure regulating pump 207 controller.

[0043] The air pressure sensor 304, the air flow valve 305 and the air valve controller 306 are arranged on the air passage branch pipe 303.

[0044] The pressure regulating pump 207 controller, the air valve controller 306 and the on-off electromagnetic valve 7 are electrically connected with the main controller 6.

[0045] The air compressor 301 is a screw type air compressor 301. Compared with other types of compressors, the screw type air compressor 301 has the advantages of stable operation, low noise, high energy saving and efficiency.

[0046] The filter 8 is arranged between the water storage tank 201 and the water pump 202, and the filter 8 includes a cloth bag type filter 801 and a precision filter 802.

[0047] The water storage tank 201 is used for storing dust falling water, and the cloth bag type filter 801 and the precision filter 802 are arranged between the water storage tank 201 and the water pump 202. The cloth bag type filter 801 can preliminarily filter larger particle impurities in the water, and the precision filter 802 can further remove small particles, so that the water entering the water pump 202 has high cleanliness, and damage of impurities to the water pump 202 and subsequent pipelines is prevented, and the service life of the equipment is prolonged.

[0048] Referring to Figure 4 The spray head 102 includes a water inlet pipe 103, a nozzle 104 arranged at the end of the water inlet pipe 103, two arc-shaped grooves 105 oppositely arranged on the outer wall of the water inlet pipe 103, a sliding block 106 matched with the arc-shaped grooves 105, a impeller 107 fixed in the nozzle 104, an elongated channel 110 arranged in the middle of the impeller 107, and an elastic member 108 arranged in the arc-shaped groove 105.

[0049] The spray head 102 is a striker head, and the elongated channel 110 and the inner wall of the nozzle 104 form a Laval tube structure.

[0050] Referring to Figure 5 , the elongated channel 110 in the middle of the impeller 107, which is in communication with the inner wall of the nozzle 104, forms a Laval tube structure. When the water flow passes through the elongated channel 110 into the nozzle 104, the flow rate will increase due to the characteristics of the Laval tube, and a mist is generated after impacting the needle head of the striker 109. The elastic member 108 in the arc-shaped groove 105 can provide a certain resistance and return action when the impeller 107 drives the nozzle 104 to rotate. The water flow impacts the impeller 107, thereby driving the nozzle 104 to rotate, and the elastic member 108 makes the nozzle 104 rotate in a reciprocating motion.

[0051] From the nozzle itself, according to the working principle of the Laval tube, when the water enters the converging section at subsonic speed, that is, the elongated channel 110 corresponds to the converging section, the flow rate gradually increases, and the pressure gradually decreases. At the throat of the channel, the flow rate reaches the speed of sound. In order to make the water smoothly accelerate to the speed of sound after entering the Laval tube structure, the water flow needs to be accelerated for the first time in the area bin 401 to provide enough power to overcome the speed of the pipeline resistance. For the striker nozzle, the water pressure impacting the striker 109 needs to reach 40 to 60 kilograms to fully atomize, and 70% of the atomized particles reach below 10 microns.

[0052] Working process: after the system is started, the screw air compressor 301 starts to work, compresses air and delivers it to the water-gas distribution device 4 through the air pipe 302. The water in the water storage tank 201 is pressurized by the water pump 202 after two-stage filtration and is sent to the water pipe 203. The dust concentration sensor monitors the dust concentration in different areas of the grain bin in real time and transmits the data to the main controller 6. The main controller 6 adjusts and controls the required water and gas flow of each area according to the dust concentration data, and sends control instructions to the pressure regulating pump 207 controller, the gas valve controller 306 and the on-off electromagnetic valve 7. The pressure regulating pump 207 controller adjusts the working state of the pressure regulating pump 207 according to the instructions to change the water pressure, and the water flow valve 206 adjusts the opening degree according to the instructions to control the water flow; the gas valve controller 306 adjusts the opening degree of the gas valve to control the gas flow. The water and gas enter the area bin 401 of the water-gas distribution device 4 through the water branch pipe 204 and the air branch pipe 303, respectively. In the gas-liquid mixing chamber 403 of the area bin 401, the water and gas are fully mixed, the water flow is accelerated through the Laval tube structure, and then delivered to the spray pipe 101 through the water-gas branch pipe 402. After receiving the water-gas mixture, the spray head 102 on the spray pipe 101 uses the structure of the Laval tube itself to accelerate the water flow for the second time, further converts the water-gas into fine water mist, and sprays out through the striker 109 to realize atomization, thereby realizing dust reduction in different areas of the grain bin.

[0053] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
