Boiler waste gas processing device

Abstract

A boiler waste gas processing device comprises a dedusting box, a waste heat recovering box, an electrolysis box, a denitration box, and a spraying desulfurization box. The left-lower end of the dedusting box is provided with an air suction draught fan; the dedusting box is connected to the waste heat recovering box through a first gas pipe, which is arranged on the left side of the top end of the dedusting box; the waste heat recovering box is connected to the electrolysis box through a second gas pipe; the electrolysis box is connected to the denitration box through a third gas pipe; and the denitration box is connected to the spraying desulfurization box through a fourth gas pipe. The provided boiler waste gas processing device can effectively purify boiler waste gas, and is capable of effectively utilizing the thermal energy of boiler waste gas to heat cold water so as to avoid waste of thermal energy.

Description

Technical field [0001] The invention involves the field of chemical exhaust gas treatment, especially a boiler exhaust gas treatment device. Background technique [0002] The progress of human beings is inseparable from the development of the industry. At the same time as industrial development, it has also brought a series of hidden dangers to human beings. Heart disease and various respiratory diseases have become one of the largest killers in human health.At present, most of the boilers, burners, steam engines and other equipment used in industries are mostly used as raw materials such as coal carbon, natural gas or diesel, and even biomass fuels are more and more valued by humans.It contains harmful substances such as sulfur dioxide, carbon monoxide, dust, impurities, fine particulate matter. Once these substances are absorbed by the human respiratory organs, they will seriously affect human health.There are also various chimneys to discharge a large amount of dust into the a...

Problems solved by technology

At present, most of the boilers, burners, steam engines and other equipment used in industry use coal, natural gas or diesel as raw materials, and even biomass fuels are getting more and more attention from human beings. Contains harmful substances such as sulfur dioxide, carbon monoxide, dust, impurities, and fine particles. Once these substances are absorbed by the human respiratory organs, they will seriously affect human health.

There are also various chimneys that discharge a large amount of dust into the air, pollute the environment, and cause serious harm to people's health. Some companies only discharge the waste gas at high altitudes. Although the operating factory area is a little cleaner, but This approach is only a transfer of pollution, and will still pollute the atmosphere and the surrounding environment.
