[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-8In this embodiment of the utility model, a water curtain dust removal device includes a dust removal cabinet 1, on the upper surface of which a dust removal centrifugal fan 2 is installed; a spray circulation mechanism 3 is installed on one side of the dust removal cabinet 1.

[0034] The spray circulation mechanism 3 includes a sewage collection tank 31. The sewage collection tank 31 has a sediment discharge port on the rear side and a filter box 32 connected to the rear side. The filter box 32 has multiple filter screens 33 arranged in a rectangular array on the inner side and a handle and maintenance cover 34 installed at the top. The rear side of the filter box 32 is connected to the circulating water pump 35 through a quick-connect coupling.

[0035] The upper end of the circulating water pump 35 is connected to the main water supply pipe 36, and the upper end of the main water supply pipe 36 is connected to the branch water pipe 37 and the branch water pipe 39 respectively through quick-connect couplings.

[0036] The other end of the branch water pipe 37 is connected to the spray pipe 38, which is located inside the purification channel 16.

[0037] The lower end of the branch water pipe 39 is connected to the water curtain generating pipe 310. Multiple water curtain nozzles are installed on the water curtain generating pipe 310 in a rectangular array, and the front side of the water curtain generating pipe 310 is mounted on the mounting plate 14.

[0038] By adopting the above technical solution, the dual effects of the water curtain formed by the water curtain generating pipe 310 and the water mist of the spray pipe 38, combined with the air guiding design of the air guide plate in the purification channel 16, greatly improve the dust capture rate, especially the purification effect of fine dust.

[0039] In the spray circulation mechanism 3, the sewage collection tank 31, the filter box 32 and the circulating water pump 35 form a closed loop system. The water purified by the filter screen 33 can be reused, saving more than 60% of water compared with traditional spray equipment.

[0040] The handle and inspection cover 34 at the top of the filter box 32 make it easy to quickly open for cleaning or replacement of the filter screen 33; all pipes are connected by quick-connect couplings, which improves disassembly and assembly efficiency by 50% and reduces maintenance costs.

[0041] The handle and inspection cover 34 at the top of the filter box 32 make it easy to open quickly for cleaning or replacement of the filter screen 33; all pipes are connected by quick-connect couplings, which improves disassembly and assembly efficiency by 50% and reduces maintenance costs.

[0042] In this embodiment, the mounting plate 14 is fixedly installed on the inner side of the upper end of the main frame 11, the inner side of the lower end of the main frame 11 is provided with a water receiving groove 12, and the inner side of the lower end of the main frame 11 is provided with a drainage groove 13, which is connected to the left side of the sewage collection box 31.

[0043] A flow equalization plate 15 is fixedly installed on the inner side of the main frame 11. The flow equalization plate 15 is located at the lower end of multiple water curtain nozzles on the water curtain generating pipe 310. A purification channel 16 is installed on the rear side of the flow equalization plate 15. Multiple air guide plates are installed in the purification channel 16.

[0044] The purification channel 16 is provided with an exhaust port at the upper end, and a dust removal centrifugal fan 2 is provided at the upper end of the exhaust port; a control box 17 is installed on the upper outer surface of the right side of the frame 11.

[0045] By adopting the above technical solution, the fan speed and spray flow can be flexibly adjusted through the control box 17, which is suitable for scenarios with different dust emission levels such as mines and workshops. In addition, the main frame 11 adopts a modular design, which is convenient for installation and expansion.

[0046] The working principle of this utility model is as follows: the centrifugal fan 2 generates negative pressure, which draws the dust-laden gas from the outside into the dust collection cabinet 1 and guides it to the top of the flow equalization plate 15 via the main frame 11; the circulating water pump 35 delivers the clean water treated by the filter box 32 to the main water supply pipe 36, wherein the branch water pipe 39 guides the water into the water curtain generating pipe 310, and a uniform water curtain is formed through the rectangular array water curtain nozzles; when the dust-laden gas passes through the water curtain, large dust particles are directly intercepted by the water curtain, and some dust falls into the water receiving tank 12 with the water flow.

[0047] After the gas is initially treated by the water curtain, it is evenly distributed by the flow equalization plate 15 and enters the purification channel 16. At this time, the branch water pipe 37 delivers water to the spray pipe 38, which sprays water mist into the purification channel 16, making full contact with and condensing the fine dust in the gas. The air guide plate further extends the gas residence time and improves the purification efficiency. The sewage after intercepting the dust is collected in the water receiving tank 12 and then flows into the drainage tank 13, and finally into the sewage collection tank 31. After some sediment is discharged through the sediment discharge port, the sewage enters the filter box 32 and is filtered step by step through multiple filter screens 33. The purified water is pumped back to the main water supply pipe 36 by the circulating water pump 35 to realize the water resource recycling.

[0048] The dual effects of the water curtain formed by the water curtain generating pipe 310 and the water mist from the spray pipe 38, combined with the air guide plate design inside the purification channel 16, greatly improve the dust capture rate, especially for fine dust purification.

[0049] In the spray circulation mechanism 3, the sewage collection tank 31, the filter box 32 and the circulating water pump 35 form a closed loop system. The water purified by the filter screen 33 can be reused, saving more than 60% of water compared with traditional spray equipment.

[0050] The handle and inspection cover 34 at the top of the filter box 32 make it easy to quickly open for cleaning or replacement of the filter screen 33; all pipes are connected by quick-connect couplings, which improves disassembly and assembly efficiency by 50% and reduces maintenance costs.

[0051] The flow equalization plate 15 ensures that the gas flows evenly through the water curtain, avoiding excessively high local concentrations that could affect the purification effect; the drainage trough 13 is directly connected to the sewage collection box 31, reducing the risk of sewage residue and secondary pollution.

[0052] The fan speed and spray flow can be flexibly adjusted through the control box 17, which is suitable for scenarios with different dust emission levels, such as mines and workshops. The main frame 11 adopts a modular design, which is convenient for installation and expansion.
