Description

technical field [0001] The present invention relates to a negatively charged membrane-based haze removal agent and an ambient air haze removal method, in particular to a method for manufacturing a membrane-based haze removal agent with a certain toughness and stability of a negatively charged water-soluble membrane phase carrier—a film bubble And ambient air haze removal method. Background technique [0002] At present, with the development of industrial technology and the improvement of people's living standards, the air haze pollution mainly caused by the positively charged PM10 and PM2.5 fine dust particles produced in people's production and life and natural disasters has It is very serious and seriously affects people's health. Large and medium-sized cities have to relocate or shut down coal-fired industrial kiln enterprises, and implement stricter emission restrictions for enterprises and vehicles. Nevertheless, the increasingly serious ambient air haze pollution is ac...

Problems solved by technology

Its technical problem: the one, its two kinds of environment-friendly surfactant aqueous solution foams are the same as common surfactant aqueous solution foams, even change into air in the aqueous solution, its environment-friendly surfactant aqueous solution foams still only have common surfactant The adhesion of the agent foam, and the foam still has low mechanical strength and poor stability, and cannot effectively complete the role of drifting and adhering dust in the atmosphere

It is well known that a large amount of surfactant foam is better than water spray dust removal, and can be used to remove dust in a limited local space, or dust generated by ground surface operations and mine operations. This method is usually called foam. Dust removal, but it is not feasible to purely use surfactant foam to purify the fine dust in the open super large space, especially the dust in the laminar flow of the atmosphere, because it is impossible to create a large amount of foam necessary for foam dust removal; It is trying to use the principle of hydrogen balloons to inject a light gas that is much lighter than air into the surfactant aqueous solution, and the foam strength of the surfactant is extremely low and cannot bear much expansion force in the air. Under high atmospheric humidity, it is very easy to dehydrate and burst. The environmentally friendly surfactant foam produced by it rapidly expands and breaks up within 1000m height during the ascent process. It is said that it is not feasible from theory to practice

Secondly, the cost of its light gas is high, and the order of magnitude of the foam produced by its process method is too low compared to the amount of foam necessary for foam dust removal using a large amount of foam in a limited space, which is far less than the foam dust removal unit volume space. The necessary amount of foam is also impossible to meet the requirements of purifying urban smog
