The dust removal equipment filters through a filter plate, and nozzle two sprays water on the gas so that the particles in the gas are adsorbed on the water droplets. Then the water with dust particles is filtered through the filter and falls to the bottom of the box. The filtered water is pumped to nozzle two through a pump for recycling, saving water resources. The filter is turned over, and the electric push rod drives nozzle one to move downward. The external water tank transmits water to nozzle one through a connecting pipe to flush the filter and flush the dust off. The filter can be removed and replaced through the lock.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a desulfurization, denitrification and dust removal device.

[0027] The utility model provides Figure 1-Figure 3 The desulfurization, denitrification and dust removal equipment shown comprises two symmetrically arranged processing boxes 1, the tops of the two processing boxes 1 are fixed with purification towers 3 through connecting rods 2, the bottoms of the processing boxes 1 are provided with air inlets, the bottoms of the purification towers 3 are connected with vertical pipes 4, the bottoms of the vertical pipes 4 are connected with switching covers 5, the lower ends of both sides of the switching covers 5 are connected with guide pipes 6, the guide pipes 6 are connected with the tops of the processing boxes 1, and the pipe walls of the vertical pipes 4 are fixed with air pumps 22;

[0028] A dust filter 7 is slidably passed through the back side of the treatment box 1, a desulfurizer 8 is laid on the top of the dust filter 7, a through hole for plugging the dust filter 7 is opened on the back side of the treatment box 1, a cover plate 19 is fixedly provided on the back side of the dust filter 7, and the cover plate 19 and the treatment box 1 are screwed and fixed by bolts 20;

[0029] An alkali liquid pool 9 is fixedly provided at the lower end of the outer wall of the purification tower 3, a water spray pipe 10 is fixedly penetrated through the side of the purification tower 3, a plurality of nozzles 11 are connected at the upper end of the water spray pipe 10, and the lower end of the water spray pipe 10 extends into the alkali liquid pool 9 and is fixedly provided with a liquid extraction pump 12.

[0030] Before treating the flue gas, dust filters 7 are installed in both treatment boxes 1, and the internal components of the switching cover 5 are adjusted so that the flue gas flows out only through the right treatment box 1. At this time, the vacuum pump 22 is started, so that the external flue gas contacts the dust filter 7 through the bottom air inlet of the right treatment box 1. First, the dust inside the flue gas is removed, and then the flue gas contacts the desulfurizer 8 to clean the sulfide inside the flue gas. Then, the flue gas enters the purification tower 3 through the guide pipe 6 and the vertical pipe 4, and the liquid extraction pump 12 is turned on at this time, so that the alkali liquid inside the alkali liquid pool 9 is sprayed into the purification tower 3 through the water spray pipe 10 and the nozzle 11, so as to treat the nitrogen compounds inside the flue gas, thereby completing the effective purification of the flue gas.

[0031] In order to be able to quickly switch between the two processing boxes 1, it is convenient to perform purification work and quickly replace the dust filter 7 at the same time. Figure 2 , Figure 3 As shown, a rotating rod 13 is rotatably provided on the side of the switching cover 5, and two symmetrically arranged sealing plates 14 are fixedly provided on the rod wall of the rotating rod 13. The side walls of the sealing plates 14 are in contact with the inner wall of the switching cover 5, and a rotating switching mechanism is provided at the end of the rotating rod 13. The rotating switching mechanism includes a connecting plate 15, which is located on the outer side of the switching cover 5 and is fixedly connected to the rotating rod 13. An insertion rod 16 is slidably penetrated inside the connecting plate 15. Two symmetrically arranged slots 17 are provided on the outer wall of the switching cover 5, and the insertion rod 16 is plugged into the slot 17. A spring 18 is sleeved on the rod wall of the insertion rod 16, and the two ends of the spring 18 are respectively fixedly connected to the switching cover 5 and the insertion rod 16, and a pull ring 21 is hinged at the end of the insertion rod 16.

[0032] When the dust filter 7 inside the right-hand processing box 1 is blocked after long-term use, the pull ring 21 can be used to pull the insertion rod 16 so that the insertion rod 16 is pulled out from the slot 17 and the spring 18 is stretched, and then the connecting plate 15 is pushed so that the connecting plate 15 drives the rotating rod 13 to rotate, and the sealing plates 14 on both sides of the rotating rod 13 can rotate, so that the left-side guide pipe 6 is connected with the vertical pipe 4. At this time, the left-hand processing box 1 can be used, and then the pull ring 21 is released, so that the insertion rod 16 is inserted into the slot 17 under the elastic force of the spring 18, and the position of the sealing plate 14 is determined. During the use of the left-hand processing box 1, the dust filter 7 inside the right-hand processing box 1 can be taken out for cleaning and replacement, thereby improving the operating convenience of the equipment.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
