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

Embodiment 1

[0033] The negatively charged film method haze removal agent of the present embodiment is mainly made up of negatively charged film-forming agent and foaming agent; select Capresin 1205A type and sodium carboxymethyl cellulose as the negatively charged film-forming agent, select dodecyl Sodium sulfate, rosin thermal polymer, alkylphenol polyoxyethylene ether OP-2 are foaming agents, and the negative film-forming agent is 29% by mass percentage (of which 10% of Cape resin 1205A type, sodium carboxymethyl cellulose 19%), foaming agent 71% (among them sodium lauryl sulfate 45%, rosin thermal polymer 10%, OP-2 16%) proportional ingredients, add water equivalent to twice the mass of negatively charged membrane haze removal agent , and mix evenly to obtain a paste-like negatively charged film-based haze remover.

[0034] Take the paste negative electrophoretic membrane haze removal agent obtained in this embodiment, and carry out a test in a ravine landform area where mining, simple...

Embodiment 2

[0038] The negative film method haze removal agent of this embodiment is mainly composed of negative film forming agent and foaming agent. Anionic polyacrylamide and sodium alginate are selected as negatively charged film-forming agents, and fatty alcohol sodium sulfate (K 14 ), sulfosuccinate 403, and alkylphenol polyoxyethylene ether OP-2 are foaming agents, and the negative film-forming agent is 40% by mass percentage (including anionic polyacrylamide 30%, sodium alginate 10%) : Foaming agent 60% (of which fatty alcohol sodium sulfate 40%, sulfosuccinate 403 10%, OP-2 10%) proportioned ingredients, add water equivalent to 3 times the mass of negative membrane haze removal agent, mix well That is, the paste-like film method haze removal agent is obtained.

[0039] Get the paste film method haze removal agent of present embodiment, carry out test to certain mountainous town. The town prospers due to individual mining and smelting, but the regional air mobility in the town i...

Embodiment 3

[0043] In this embodiment, polyvinylpyrrolidone (PVP) and polyanionic cellulose are selected as the negatively charged film-forming agent, and sodium dodecylbenzenesulfonate is selected as the foaming agent, and the negatively charged film-forming agent is 38% by mass percentage (wherein polyethylene Pyrrolidone PVP-K30 18%, polyanionic cellulose 20%): Foaming agent 62% (sodium dodecylbenzene sulfonate 62%) proportioned ingredients, mix evenly to get powder membrane haze remover.

[0044] Get the powdery membrane method haze removal agent obtained in this embodiment, and carry out the test to a certain mountainous county. Because there are many coal mining and coking individual enterprises in the surrounding area, the atmosphere in the area is gray and hazy all the year round, and there is a peculiar smell in the air. The detection of PM2.5 > 500 is off the table. It is planned to release a negatively charged water-soluble membrane phase-bubble carrier on the top of 3 high-ris...

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...
