DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] An air purification and dust removal device for environmental protection engineering, comprising a box 1:

[0021] A cylinder 2 extending to the inner bottom of the box body 1 is arranged above the box body 1, wherein a plurality of groups of flow guide scoops 3 connected to the corresponding inner wall of the box body 1 are radially arranged on the outer wall of the cylinder 2, and a round tube I4 corresponding to the flow guide scoop 3 is arranged on the side wall of the box body 1, and a round tube II5 is screwed inside the round tube I4, wherein a filter screen 6 is arranged inside the round tube II5;

[0022] The side wall of the cylinder 2 is provided with a communication port 7 connected to the guide bucket 3, wherein two groups of spray mechanisms 8 are arranged in parallel in the cylinder 2 at the top of the communication port 7, and an air suction component 9 is arranged between the two groups of spray mechanisms 8, and a filtering mechanism 10 is also arranged at the top of the cylinder 2;

[0023] The spray mechanism 8 includes a circle of spray pipes 81 arranged in the cylinder 2, wherein a plurality of groups of spray heads 82 are arranged on the side wall of the spray pipe 81 obliquely downward, and two groups of spray pipes 81 are connected to the bottom of the cylinder 2 through a circulation pipe 84, and a water pump 83 is arranged on the circulation pipe 84;

[0024] The filtering mechanism 10 includes a dust filter bag 101 which is sleeved on the top of the cylinder 2, and the dust filter bag 101 is fixed to the top of the cylinder 2 by a clamp, wherein a bracket 102 is also provided at the top of the cylinder 2, and a vertical rod 103 is fixed to the top of the bracket 102 by a screw tube 104, and an arc rod 105 is provided at the top of the vertical rod 103 for supporting the inner top wall of the dust filter bag 101.

[0025] like Figure 1 As shown, a truncated cone-shaped protective cover 11 is arranged at the top of the cylinder 2 and is located above the spray mechanism 8 , wherein a bracket 102 is arranged on the protective cover 11 .

[0026] In this embodiment, a sewage pipe and an overflow pipe extending to the outside of the box body 1 are arranged at the bottom of the cylinder 2, wherein the overflow pipe is located below the connecting port 7, and a water inlet pipe connected to the liquid storage tank is arranged on the circulation pipe 84.

[0027] The air suction assembly 9 includes a motor 91 , wherein the motor 91 is fixed on a crossbar in the cylinder 2 , and a fan blade 92 is provided at the bottom end of the output shaft of the motor 91 .

[0028] like Figure 1 As shown, a circular ring 12 located outside the circular tube I4 is provided on one end of the circular tube II5, wherein the installation position of the filter screen 6 is below the installation position of the circular ring 12, and an annular seat 13 is provided in the circular tube II5 on the same side as the circular ring 12.

[0029] like Figure 1As shown, an inclined plate 14 is provided at the bottom of the communication port 7, wherein the bottom end of the inclined plate 14 extends into the cylinder 2, and the top end of the inclined plate 14 extends into the corresponding guide bucket 3. The inclined plate 14 can shield and guide the liquid sprayed by the spray mechanism 8, so that the liquid is turned back to the bottom of the cylinder 2, and the liquid is prevented from flowing back into the guide bucket 3.

[0030] The working principle of the present invention is as follows: the suction component 9 generates negative pressure suction force, so that the external gas containing dust and other impurities enters the guide bucket 3 through the circular tube II5. At this time, the filter screen 6 in the circular tube II5 can play a preliminary filtering role on the gas, wherein the filtered gas enters the cylinder 2 through the connecting port 7 and flows upward, then the water pump 83 draws the liquid at the bottom of the cylinder 2 to the lower spray mechanism 8 through the circulation pipe 84, and the upper spray mechanism 8 is in a closed state, so that the liquid in the lower spray mechanism 8 is sprayed out through several nozzles 82 on the spray pipe 81, thereby washing the upstream gas in the cylinder 2, and at the same time, the washed gas flows into the dust removal filter bag 101 through the protective cover 11, and is filtered and discharged thereafter, thereby improving the gas dust removal effect and efficiency through the above-mentioned stepwise filtering, washing and secondary filtering of the gas.

[0031] In the above process, when the liquid at the bottom of the cylinder 2 is relatively turbid, it is discharged through the sewage pipe, the water inlet pipe is opened to pump fresh liquid into the spray pipe 81 through the circulation pipe 84 and the water pump 83 and sprayed out from the nozzle 82, and when the liquid level at the bottom of the cylinder 2 reaches the standard, the water inlet pipe is closed, and the liquid at the bottom of the cylinder 2 is recycled through the spray mechanism 8;

[0032] After stopping work, the liquid can be pumped into the upper spray pipe 81 through the water pump 83 and the circulation pipe 84 and sprayed out by a plurality of nozzles 82 to clean the fan blades 92. When there are many impurities on the filter screen 6, the circular tube II5 can be rotated out of the circular tube I4 to clean the impurities on the filter screen 6. Similarly, the dust filter bag 101 can be removed and cleaned when it is dirty. In the above process, the dust filter bag 101 is supported by the bracket 102, the vertical rod 103 and the arc rod 105 to prevent it from collapsing and failing to filter the gas well and effectively.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
