Polluted air purifying system and work method thereof

Abstract

The invention provides a polluted air purifying system and a work method thereof. The system has an advanced filter system to eliminate toxic emissions in exhaust gas. A new technology is used to capture toxic substances emitted from a pollution source or a chimney of a fire coal boiler, a nano-technology and advanced chemical reactions are used to remove pollutants in the exhaust gas, and principles of the interaction between the gas and a liquid and the interaction between the gas and a solid are applied, so a clean gas is finally emitted, and sulfuric acid and nitric acid generated in the above reaction process are recovered to make a filtering recovery system become beneficial circulation. The polluted air purifying system has a low cost, and benefits for popularized use.

Description

(1) Technical field: [0001] The invention relates to a purification system and its working method, in particular to a system and its working method for purifying polluted air. (two) background technology: [0002] In the form of China's sustained and rapid economic development, the demand for energy consumption has risen sharply; taking coal as an example, the annual increase in demand for coal since the reform and development has been about 8-12%, and the biggest problem resulting from this is serious air pollution. pollute. [0003] China today is one of the countries with the worst air pollution in the world (after India). Not long ago, at the regular meeting of the State Council of China, the theme of "eliminating people's heart and lung problems" was specifically raised; combining pollution control with public attitudes and livelihoods, we are determined to get rid of the hat of a big polluting country. The Chinese government has decided not only to take off economica...

AI Technical Summary

Problems solved by technology

However, the efficiency of cheap dust removal equipment is very low, usually less than 80%; good equipment such as electrostatic dust removal, although the efficiency can be as high as 99%, but it also has its fatal shortcomings: (1) The equipment is huge, consumes a lot of steel, and requires high voltage transformers. Electricity and rectification equipment, so the investment is high

(2) The dust removal efficiency is restricted by the specific resistance of the dust. Generally, the specific resistance of dust is less than 104-105 ohms per centimeter or greater than 1010-1011 ohms per centimeter. If certain measures are not taken, the dust removal efficiency will be affected. (3) Not available Off-line maintenance function, once the equipment fails, or runs with a disease, or can only be shut down for maintenance

[0014]The current purification equipment is expensive, and the waste after purification cannot be recycled and reused, which easily leads to the trouble of secondary pollution
