White smoke removal equipment for flue gas from exhaust chimney of chemical plant

Abstract

The invention discloses white smoke removal equipment for flue gas from an exhaust chimney of a chemical plant. The white smoke removal equipment structurally comprises a suction fan, a flue gas treatment device, a flue gas white smoke removal machine body, a flue gas inlet, a drain outlet and supporting legs, wherein the suction fan is mounted at the inner top of the flue gas white smoke removalmachine body; and the flue gas treatment device connected with the flue gas white smoke removal machine body is arranged below the suction fan. Compared with the prior art, the invention has the following beneficial effects: water and particles can be quickly separated, so cyclic utilization of water and collection of particles are facilitated; a shaking head moves up and down, so up-and-down shaking of filter screen is realized, and thus, the filter screen can be effectively prevented from being blocked, timely drainage of water is realized, flowing of water is prevented, and particles can slide down from high potential to low potential and are discharged from the drain outlet; and by additionally arranging a flue gas uniform-dispersing plate, flue gas can uniformly ascend and diffuse, the phenomenon that a water uniform-spraying device is blocked due to accumulation of the flue gas at one position is avoided, particles can uniformly fall onto the high-strength filter screen, the phenomenon that the filter screen is overloaded and damaged due to concentrated falling of the particles fall onto a certain position of the filter screen is avoided, and the filter screen is further prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a flue gas dewhitening equipment for exhaust chimneys of chemical plants. Background technique [0002] In recent years, with the continuous development of the industrial industry, the construction scale of chemical plants has continued to increase, and the production capacity of chemical plants has continued to increase. The smoke pollution caused by the exhaust smoke of chemical plants has become increasingly serious, and the white smoke from chimneys will affect the environment. When cold air is mixed, during the cooling process, the water vapor contained in it is saturated and condensed, and the condensed water droplets refract and scatter the light, making the smoke plume appear white or gray, which is called "wet smoke plume", which will bring visual The problem of pollution will affect flight, highway transportation, etc., so it is necessary to d...

AI Technical Summary

Problems solved by technology

[0003] The dewhitening treatment will spray the flue gas. In order to recycle the water, it is necessary to separate the water from the particles, and often use a filter screen. However, the existing flue gas dewhitening equipment uses a static filter screen. The particles after spraying are all wet and easily stick to the filter screen, which will cause the filter screen to be blocked, so that the water cannot be discharged in time and is easy to flow back
