Atmospheric pollution purificant and preparation method, application of purificant and application method thereof

Abstract

The invention discloses an atmospheric pollution purificant and a preparation method, the application of a purificant and an application method thereof, wherein the purificant is formed by covering hydroxypropyl alkyl cellulose with a sorbitan fatty acid ester outer film; the preparation method of the purificant comprises the following steps of: adding 20-40 parts by weight of hydroxypropyl alkyl cellulose to 200-400 parts by weight of water at a temperature ranging from 80 to 90 DEG C, stirring under more than two barometric pressures for dissolving for 10-20 minutes, next, adding 600-700 parts by weight of water for dissolving for 20-40 minutes by stirring, and then adding 0.5-2 parts by weight of sorbitan fatty acid ester, and stirring for 10-20 minutes to obtain the purificant solution. The atmospheric pollution purificant is sprinkled to the atmosphere by the dosage of 50-200g / m3 of atmosphere, and capable of effectively adsorbing and removing suspended particles in the atmosphere; the removal rate of the suspended particles in the atmosphere can be 98%.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a cleaning agent for air pollution. Background technique [0002] Exhaust gas from automobiles, gas emitted from burning coal in power plants, gas emitted from burning coal in households and factories, and even smoke emitted from smoking, etc., diffuse into the atmosphere in large quantities, resulting in an increasing concentration of harmful smoke in the atmosphere , These are very harmful to the human body. For environmental science, suspended particles specifically refer to those fine pollutants in the air, which are a major source of air pollution. Among them, suspended particles with a diameter of less than 10 microns are defined as respirable suspended particles, which can accumulate in the lungs and endanger human health. Particles with a diameter of less than 2.5 microns are the most harmful to the human body because they can directly enter the alveoli. Scien...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no good removal method for suspended particles in the atmosphere, especially particles with a diameter of less than 2.5 microns. We can only control them from the source and limit the factories and automobile exhaust gases that produce pollution sources. However, the effect of this restriction is It is not ideal, so there is actually no fundamental solution to the problem of air pollution, and there is no effective way to improve and purify the polluted atmosphere
