Environment-friendly treatment device for flue gas denitrification and nitrogen fertilizer co-production

Abstract

The invention relates to the technical field of flue gas denitrification environmental protection, and particularly relates to an environmental protection treatment device for flue gas denitrificationand nitrogen fertilizer co-production. A sealed smoke inlet pipe is arranged in the middle of the bottom end of a filter box in a penetrating mode, a sealed smoke outlet pipe is arranged in the middle of the top end of the filter box in a penetrating mode, and by arranging a regulating valve and a temperature measuring meter, the temperature in the filter box can be quickly observed by a worker,so that the temperature in the filter box can be adjusted, the worker can quickly master the temperature change more conveniently, and the temperature can be adjusted by quickly adjusting and controlling the water flow. Through the arrangement of the overall structure, a cooling cycle can be achieved on the whole, circulation and replacement of media in the cooling plate are kept, the temperaturein the filter box is kept in a replaced mode, and it is further avoided that the temperature of the media is higher than the temperature of flue gas all the time and the temperature cannot be guaranteed to be within a normal range. In addition, the structure is convenient and efficient and suitable for wide use.

Description

technical field [0001] The invention relates to the technical field of flue gas denitrification and environmental protection, in particular to an environmental protection treatment device for flue gas denitrification and co-production of nitrogen fertilizer. Background technique [0002] At present, among the pollutants that cause the above-mentioned atmospheric environmental problems, NOX occupies three items, which shows that it has a great impact on nature. NOX is not only the basis of nitric acid rain, but also one of the main substances that form photochemical smog and destroy the ozone layer. Strong toxicity, harmful to the human body, environment, ecology, and great damage to the social economy. Like SO2, NOX will fall to the ground through dry deposition and wet deposition in the atmosphere. The final destination is nitric acid Salt or nitric acid, nitric acid type acid rain is more harmful than sulfuric acid type acid rain, because it acidifies water bodies, leaches...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an environmental protection treatment device for flue gas denitrification and co-production of nitrogen fertilizer, so as to solve the problem that the working efficiency of the electrostatic precipitator is reduced due to excessive flue gas temperature, and to further prevent the flow in the process from being blocked due to too many particles in the flue gas. Blockage, which leads to the paralysis of the whole process and cannot denitrify the flue gas in time, thus increasing the hazard probability of harmful gases containing nitrate entering the atmosphere
