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 easy to dehydrate and crack, and the environmentally friendl

Abstract

The invention relates to haze-removal liquid, belonging to the technical field of air pollution treatment. The haze-removal liquid contains sodium fluosilicate, sodium water glass and water in a mass ratio of (3-5) to 25 to (250-300). The invention further discloses a preparation method of the haze-removal liquid. Compared with a water-phase haze-removal agent in the prior art, the haze-removal liquid has the advantages that the haze removal efficiency is relatively high and rapid, and meanwhile, the moisture in air is increased.

Description

technical field [0001] The invention belongs to the technical field of air pollution control, and relates to a haze removal liquid and a preparation method thereof. Compared with the existing water-phase haze removal agent, the haze removal liquid of the present invention has higher and faster haze removal efficiency, and at the same time increases moisture in the air. Background technique [0002] With the development of industrial technology and the improvement of people's living standards, atmospheric haze pollution mainly caused by PM10 and PM2. 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. However, the increasingly serious ambient air haze pollution is actually still difficult to effectively control. Haze dust drifts in the air for a long time and a long distance, with a wide range of influence. [0003] At present, the gene...
