Industrial smoke exhaust gas recovery purifier and application method thereof

Abstract

The invention discloses an industrial smoke exhaust gas recovery purifier and an application method thereof. A scheme is characterized in that: tilting grid plates are arranged in a dedusting chamber; each grid plate is provided with a grid hole; separation plates divide a purification chamber into relatively independent compartments; a main shaft penetrating through the purification chamber is fixed with rotary blades and bearings in an interval mode; one rotary blade is arranged in one compartment; and one bearing is fixed corresponding to one separation plate. By utilizing mechanical and chemical reaction principles in the invention, the reaction area and the reaction speed are increased, so the industrial smoke exhaust gas is gradually adsorbed and purified in the compartments of the dedusting chamber and the purification chamber, and the recovery rate can reach above 95%. The smoke exhaust gas is adsorbed before being discharged to airspace, so the air pollution source is greatlyreduced. An absorbent used in the invention has the advantages of low cost and high adsorption efficiency, so the purifier of the invention, which has an important meaning to the industrial smoke exhaust gas pollution reduction and the air environment purification, is an ideal industrial smoke exhaust gas adsorption purifier.

Description

technical field [0001] The invention relates to an industrial environmental protection purification device, in particular to a device for recycling and purifying industrial smoke and dust waste gas and a method for using the device, belonging to the field of environmental engineering. Background technique [0002] Global environmental degradation is a common concern of people all over the world. The United Nations Climate Conference in Copenhagen in 2009 put the issue of improving the global climate and environment on the agenda. Industrial gas emissions such as smoke, carbon dioxide, sulfur dioxide, and nitride are the main factors causing air pollution. According to statistics, one-third of my country's urban population breathes heavily polluted air, and one-third of the country's land is eroded by acid rain. At present, the annual discharge of industrial smoke exhaust gas in the country is between 40 and 50 million tons, and the annual discharge of sulfur dioxide that c...

AI Technical Summary

Problems solved by technology

[0003] At present, people mainly have the following kinds of methods for reducing industrial gas emissions: three-way catalytic method (patent application number: 02149809.1), this method can only reduce the emission of pollutants to a limited extent, and the products after catalysis still have carbon dioxide and carbon monoxide. , hydrocarbons, nitrogen oxides and other components; filtration method (patent application number: 01802804.7), steam adsorption method (patent application number 02135942.3), re-incineration method (patent application number: 02135942.3), etc., these methods either have too high processing costs, or The treatment effect is not good, and it has not been widely used in fact; the spray treatment method (patent application number: 96104510.8) is widely used in industries all over the world, but the disadvantage of this method is that the contact area between the spray treatment liquid and the flue gas is small , so the efficiency is low, the spray treatment liquid is mainly water, water can make the dust fall, but the adsorption force for the waste gas is small, so the industrial smoke and dust waste gas treated by this technology still has a large amount of sulfur dioxide, carbon dioxide and other gases discharged into the atmosphere middle

[0004] At present, raw coal is still the main fuel for industry. The combustion of raw coal produces a large amount of smoke and dust, sulfur dioxide, etc., which are emitted into the air. At present, the main method to reduce the emission of raw coal after combustion is to use coal washing and desulfurization technology. This technology is not only very expensive, but also cannot be effectively Reduce industrial smoke and dust emissions. In addition, the above-mentioned technical treatments have no obvious effect on reducing carbon dioxide emissions.

Over the years, the world has invested a lot of manpower and material resources in reducing industrial smoke and dust, but it has not effectively solved this problem in practical applications. A low-cost, proven method for the treatment of objects has not yet been proposed

Especially in my country, due to the lack of low-cost and high-efficiency industrial smoke and dust waste gas treatment technology and solutions, the environmental pollution and acid rain caused by industrial smoke and dust waste gas in my country have become increasingly serious.
