Smoke purifying method and smoke purifying equipment

Abstract

A smoke purifying method comprises the following steps that the sectional area of smoke is increased, the flow speed of the smoke is reduced, and part of gas and dust are naturally separated; the smoke passes through a smoke filter screen, and the gas and the dust in the smoke are separated; water mist is sprayed to the smoke, and when the smoke passes through the sprayed water mist, the dust in the smoke can be thoroughly purified out; the purified smoke passes through the filter screen for secondary purifying. The invention further provides smoke purifying equipment adopted in the smoke purifying method. By means of the smoke purifying method, 70% or above of dust in the smoke can be removed, the dust collected in the purifying process can be recycled, and meanwhile the method has the advantages of being safe, stable, reliable, easy to operate, high in adaptability and the like are achieved. The smoke purifying equipment achieves the aim of removing the dust in the smoke through the characteristic of the smoke, and is simple in structure and convenient to operate, a very good smoke purifying effect can be achieved through the equipment, and purifying cost is very low.

Description

Technical field: [0001] The invention relates to the technical field of flue gas purification, in particular to a flue gas purification method and flue gas purification equipment. Background technique: [0002] In today's society, with the development of industry, environmental pollution is becoming more and more serious, especially the pollution of flue gas is the most serious. Flue gas is a mixture of gas and smoke that directly enters the air. There are many types of furnaces in modern industry, and the exhausted flue gas is also They are different. The flue gas in the industry is emptied, but the flue gas contains a lot of smoke and dust, which will cause great pollution to the environment. With the gradual improvement of the society's awareness of energy conservation and environmental protection, and the adjustment of the country's energy policy in recent years , enterprises pay more and more attention to environmental protection awareness, but the purification of flue ...
