Method for suppressing haze in atmosphere

Abstract

The invention discloses a method for suppressing haze in the atmosphere and belongs to the technical field of haze treatment. According to the method, thylamine and diethylamine are dropwise added into acrylic monomers, a reaction is performed under a minus temperature condition, then a reaction is performed under the effect of initiator tert-butyl hydrogen peroxide, temperature is raised, nitrogen is introduced, oxygen is made to be completely discharged out of a reaction vessel, modified acrylic acid polymers are prepared through a polymerization reaction, water, salt, glycerin and the modified acrylic polymers are put in a vehicle-mounted atomizing haze removing spraying device to be dissolved evenly, then atomization is performed, and the atomized mixture is evenly sprayed into the atmosphere to treat haze. The method has the advantages that PM2.5 particles, dust, aerosol and the like in the atmosphere can be effectively captured, adsorbed and aggregated, the moistening, adhering and coagulating effects are achieved, and the purpose of removing haze is achieved; the time needed is shorter than that needed by other haze removing methods by 20% or above, the haze removing efficiency is higher than that of other methods by 18% or above, and the haze removing effect is good.

Description

technical field [0001] The invention relates to a method for suppressing haze in the atmosphere, and belongs to the technical field of haze control. Background technique [0002] Smog is a weather phenomenon that occurs when particles such as PM2.5, dust, aerosols and other particles in the floating atmosphere are relatively stable under certain weather conditions such as humidity and temperature. Smog disaster is the result of long-term air pollution. How to control air pollution is one of the urgent problems faced by all mankind. The smog weather is mainly caused by extensive development methods, unreasonable industrial structure and energy structure. The root cause is still fossil energy, one is coal burning, the other is fuel oil. In addition, the development method is relatively extensive, and a large amount of pollutants are discharged. Specifically The reasons are as follows: one is that the atmospheric air pressure is low, and air stagnation is the main factor. Due...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: aiming at the disadvantages of long time required for haze removal, low haze removal efficiency, and poor haze removal effect in the current haze control method in the atmosphere, a method of dripping ethylamine, Diethylamine reacts at sub-zero temperature, and then reacts under the action of initiator tert-butyl hydroperoxide, then raises the temperature, feeds nitrogen gas to completely exclude oxygen from the reaction vessel, and conducts polymerization reaction to obtain modified acrylic acid Polymers, water, salt, glycerin and modified acrylic acid polymers are loaded into a vehicle-mounted atomization haze removal spray device and dissolved evenly, and then atomized and evenly sprayed in the atmosphere to control haze.
