A kind of spray dust suppression agent and its preparation method and application

Abstract

The application belongs to the technical field of atmospheric dust pollution control, and in particular relates to a spray dust suppressant and its preparation method and application. The application provides a spray dust suppressant, which includes: 0.1-0.3 parts of coagulant; 0.02-0.06 parts of surfactant; 0.01-0.06 parts of defoamer; 100 part of water; the spray dust suppressant forms water mist with a particle size of 30-150 μm through atomization. The application provides a method for preparing a spray dust suppressant, comprising: mixing a coagulant, a surfactant, a defoamer and water to prepare a spray dust suppressant. The application provides a spray dust suppressant and its preparation method and application, which can effectively solve the traditional technical defect in the prior art that it is difficult to settle atmospheric dust particles below PM5.0 only by atomized water.

Description

technical field [0001] The application belongs to the technical field of atmospheric dust pollution control, and in particular relates to a spray dust suppressant and its preparation method and application. Background technique [0002] Haze is a large number of extremely fine dry dust particles evenly floating in the air, making the air with horizontal visibility less than 10 kilometers generally turbid. The composition of haze is very complex, including hundreds of atmospheric particles. Among them, the aerosol particles with a diameter of less than 10 microns are mainly harmful to human health, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, etc., which can directly enter and adhere to the upper and lower respiratory tracts and lung lobes of the human body. Because most of the atmospheric aerosols in the haze can be inhaled by the human respiratory tract, especially the submicron particles will be deposited in the upper and lower respirat...

AI Technical Summary

Problems solved by technology

The fog cannon machine has an obvious effect on the dust reduction of particles above PM10, but the effect on the dust below PM5.0 is not obvious.

[0004] To sum up, the traditional method of only relying on water atomization for dust reduction has the technical defect that it is difficult to settle dust below PM5.0
