Then, by starting the control starter 25, the catalytic device 24 works to catalyze the mixture in the waste gas and ammonia, thereby increasing the denitrification rate. Embodiment 2

[0032] As Figures 1-6As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the dust removal assembly includes a box body 31, a baffle 32 is fixedly connected to the inner wall surface of the box body 31, an installation plate 35 is fixedly connected to the inner wall surface of the box body 31, a spring column 36 is detachably connected to the upper surface of the installation plate 35, an electrostatic dust removal plate 34 is fixedly connected to the upper surface of the spring column 36, the collection group includes a dust collection box 33, the upper surface of the dust collection box 33 is detachably connected to the bottom surface of the box body 31, a vibration pump is detachably connected to the upper surface of the installation plate 35.

[0034] Next, specifically describe the working principle of the desulfurization and denitrification treatment equipment.

[0035] As Figures 1-6As shown in the figure, when using the desulfurization and denitrification treatment equipment, the waste gas is introduced into the housing 21, and at the same time, nitrogen gas is introduced into the housing 21 through the ammonia input device 22 to mix with the waste gas. Then, by starting the control starter 25, the catalytic device 24 is made to work to catalyze the mixture in the waste gas and ammonia, thereby increasing the rate of denitrification.

By starting the liquid extraction pump 43, the purified liquid stored in the purified liquid storage tank 42 is pumped into the connecting pipe 45. Then it is transported to the drain pipe 46 by the connecting pipe 45 and finally atomized and sprayed out by the atomizing nozzle 47, so as to facilitate the mixing reaction with the sulfide in the waste gas, thereby achieving the purpose of desulfurization.
