Gas injection device and method for preventing and controlling urban haze

Abstract

The invention discloses a gas injection device for preventing and controlling urban haze. An environment-friendly active agent and water are mixed to prepare an aqueous surfactant solution, and mixedgas lighter than air is introduced into the aqueous surfactant solution by a tube aerator, so that a large quantity of bubbles are produced; after the mixed gas, the surfactant solution and water areaerated, the bubbles are suspended at the top inside a gas-liquid mixing box, then the bubbles are conveyed to the outside through an exhaust motor, an exhaust wheel and a gas outlet pipeline, float in air and rise to the sky gradually, surface energy of the bubbles is large when the bubbles are mixed into the outside (atmosphere), tiny particles with size of PM10 or smaller in air can be adsorbed, when the bubbles adsorb sufficient tiny particles, the surface energy is reduced and weight is increased, the bubbles can be broken, and the tiny particles become heavier particles and freely fall to the ground like raindrops. The injection device is one good device for preventing and controlling PM2.5 at present and has broad market application space.

Description

technical field [0001] The invention relates to a gas injection device, in particular to a gas injection device for preventing urban smog. Background technique [0002] Nature is the source of beauty, it is sublime and elegant, majestic and soft. Human beings have been thinking about how to get along with nature, especially in today's increasingly advanced material civilization, the relationship between human beings and nature needs to be paid more attention to. [0003] The smog that has occurred in recent years is due to the fact that the natural environment cannot withstand the environmental collapse caused by human over-exploitation and utilization. The optimization and maintenance of the urban environment not only requires urban managers to scientifically formulate planning outlines and effectively control economic industries and key points, but also requires the conscious participation of urban residents to advocate green, low-carbon and friendly living and travel hab...

AI Technical Summary

Problems solved by technology

[0004] At present, in the process of preventing and controlling smog, most of people use air purification devices and protective masks, etc., and some devices used in a small part are only used in local small areas, which is extremely insufficient for the control of smog. Therefore, it is necessary to find a There is still a long way to go to effectively solve the current smog problem.
