Problems solved by technology

[0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied to the chemical industry that produces many nitrogen oxides and sulfur oxides. In the published patents CN208260340U, CN207042254U and CN209093111U, the disclosed dust removal and denitrification devices are for the denitrification part It is difficult to replace the filler in the later stage, and it is impossible to ensure the maintenance of the denitrification effect. Secondly, it cannot play a preliminary purification role for the dusty sewage after spraying, which is not comprehensive enough. Therefore, we propose a dust removal and denitrification device

Embodiment 1

[0019] Such as figure 1 , 2 As shown, a dust removal and denitrification device includes a device main body 1, a denitrification device 2 is arranged on the upper end of the device main body 1, and a spray device 4 is arranged on the inner side of the device main body 1 close to the bottom of the denitrification device 2, and the inner side of the device main body 1 is far away from the spraying device. The filter device 3 is arranged below the shower device 4 .

[0020] The spraying device 4 includes a water inlet pipe 41 and two sets of branch pipes 42. The branch pipe 42 communicates with the water inlet pipe 41. The water inlet pipe 41 is fixedly connected to the outer surface of the device main body 1. The direction of the water inlet pipe 41 is far away from the device main body. The lower end of one side of 1 is bent in an L shape to facilitate the connection of the external water pipe. One end of the branch pipe 42 is closed and fixedly connected with the inner wall o...

Embodiment 2

[0022] On the basis of Embodiment 1, such as image 3 As shown, the denitrification device 2 includes a top cover 21, a connecting column 22, a material tray 23, a ventilation net 24 and a filter packing 25. The top cover 21 is movable to cover the upper end of the device main body 1, and the connecting column 22 is vertically connected to the lower end of the top cover 21. The center of the outer surface is fixedly connected, and the connecting column 22 runs through the inside of the two groups of trays 23. The outer surface of the lower end of the tray 23 is provided with a ventilation net 24, and the filter filler 25 is filled in the inner side of the tray 23. The surface is provided with an exhaust port 26, and the exhaust port 26 is connected to the bottom of the top cover 21 in a cylindrical shape. The quantity of the exhaust port 26 is two groups to ensure that the gas is better discharged.

Embodiment 3

[0024] On the basis of embodiment one and embodiment two, such as Figure 4 As shown, the filter device 3 includes an outer frame 31 attached to the inner wall of the device main body 1, and a filter screen 33 fixedly arranged on the inner side of the outer frame 31, and half of the outer frame 31 in the shape of a semicircle passes through the outer surface of the device main body 1 And it extends to the outside, and the extension position of the outer frame 31 is provided with an embedding edge 32, and the outer surfaces of the upper and lower ends of the embedding edge 32 are movably fitted between the device main body 1 to ensure the tightness of the connection and prevent gas from overflowing .

[0025] It should be noted that the present invention is a dust removal and denitrification device. When in use, the gas enters through the air inlet 5, sprays and removes dust through the spray device 4, and after denitrification by the denitrification device 2, the gas is discha...

Abstract

The invention discloses a dust removal and denitration apparatus. The apparatus comprises an apparatus body, a denitration device is arranged at the upper end of the apparatus body, a spraying deviceis arranged at the inner side, close to the lower portion of the denitration device, of the apparatus body, and a filtering device is arranged on the inner side, away from the lower portion of the spraying device, of the apparatus body. The dust removal and denitration apparatus makes an internal filtering filler conveniently replaced by arranging the denitration device, and has a preliminary filtering effect on sewage by arranging the filtering device, so convenience is brought to subsequent treatment of water.
