[0035] The following will further illustrate the present utility model in conjunction with the drawings.

[0036] The present utility model provides a water foam dust removal system, as Figure 1 shown, which includes:

[0037] Water foam dust collector. The water foam dust collector includes a vertically arranged body 1 and two atomizing nozzle assemblies disposed within the body 1 for generating water mist particles. The two atomizing nozzle assemblies are located at different heights, and the spraying range of the atomizing nozzle assemblies covers the internal cross-section of the body 1. The side of the body 1 is connected to an air inlet duct 3, and the upper end of the body 1 is connected to an air outlet duct 10 for discharging air. The connection between the air inlet duct 3 and the body 1 is lower than the atomizing nozzle assemblies. A sewage discharge port 101 is provided at the lower end of the body 1. The air inlet duct 3 can admit the dust generated after processing grains in a grain crushing workshop;

[0038] Water supply assembly. The water supply assembly includes a water tank 5 and a water pump 8. The input end of the water pump 8 is connected to the water tank 5, and the output end of the water pump 8 is connected to the input end of the atomizing nozzle assembly;

[0039] Dust collection hopper 6. The dust collection hopper 6 is disposed in the water tank 5 and is located directly below the sewage discharge port 101;

[0040] Wherein, the dust collection hopper 6 and the water tank 5 can be cleaned regularly.

[0041] It can be understood that after the dust enters the body 1 from the air inlet duct 3, it will collide, agglomerate and settle with the water mist particles generated by the atomizing nozzle assembly, and fall into the dust collection hopper 6 in the water tank 5 through the sewage discharge port 101. After the air is treated by multiple groups of atomizing nozzle assemblies, the dust therein is removed and discharged from the air outlet duct 10. That is, this water foam dust removal system can efficiently remove dust, which is beneficial to significantly reduce the dust concentration in the workshop, thereby improving the working environment, reducing safety risks, protecting the respiratory health of operators, and reducing the occurrence of occupational diseases. In addition, after the water in the water tank 5 is supplied to the atomizing nozzle assembly by the water pump 8 and sprayed out, it will fall back into the water tank 5, which is beneficial to the recycling of water and thus beneficial to reducing water resource consumption.

[0042] It should be noted that since the dust collection hopper 6 is disposed in the water tank 5, the water in the water tank 5 can play a certain role in inhibiting the dust in the dust collection hopper 6 from spreading into the air.

[0043] It should also be noted that both the water pump 8 and the exhaust fan 9 can be frequency-controlled to conveniently adjust the operating parameters according to the actual situation. In addition, a dust concentration detector can be installed at the end of the air inlet duct 3 close to the body 1, and this dust concentration detector and the water pump 8 are commonly electrically connected to a controller to make the water spraying amount of the atomizing nozzle assembly match the dust concentration.

[0044] In one embodiment, the atomizing nozzle assembly includes a plurality of atomizing nozzles 12 with the same height and the output ends facing downwards. The input ends of the plurality of atomizing nozzles 12 are all connected to the output end of the water pump 8.

[0045] It can be understood that several atomizing nozzles 12 in the same group can jointly spray water mist particles downward in multiple directions, so that the spraying range of the atomizing nozzle assembly covers the inner cross-section of the container body 1, thus avoiding spraying loopholes.

[0046] In one embodiment, the atomizing nozzle assembly includes a spray pipe 11, and the spray pipe 11 communicates with the output end of the water pump 8 and the input ends of several atomizing nozzles 12.

[0047] It can be understood that the water pumped out by the water pump 8 can be supplied to several atomizing nozzles 12 through the spray pipe 11.

[0048] In one embodiment, an exhaust fan 9 is connected to one end of the air outlet pipe 10 far away from the container body 1 to provide negative pressure, so as to ensure smooth air discharge.

[0049] In one embodiment, the lower end of the container body 1 is in a conical shape with a larger upper part and a smaller lower part, which is beneficial to making the dust converge and fall into the dust collection hopper 6.

[0050] In one embodiment, the horizontal position and size of the dust collection hopper 6 respectively match the horizontal position and size of the sewage outlet 101, which is beneficial to making the dust fall into the dust collection hopper 6 as much as possible under the action of gravity.

[0051] In one embodiment, the input end of the water pump 8 communicates with the middle part of the water tank 5.

[0052] It can be understood that since dust may settle at the lower part of the water tank 5, the input end of the water pump 8 is communicated with the middle part of the water tank 5, so that the water pump 8 pumps the relatively clear water in the middle part of the water tank 5 to supply the water mist nozzle assembly.

[0053] In one embodiment, a filter 7 is arranged at one end of the water pump 8 close to the water tank 5, which is beneficial to supplying clean water to the water mist nozzle assembly.

[0054] In one embodiment, an overflow pipe 4 is arranged on the side surface of the top of the water tank 5.

[0055] In one embodiment, several mounting seats 2 are arranged on the container body 1, which is beneficial to mounting the water foam dust collector in the workshop by using the mounting seats 2.
