Dust prevention and suppression agent

Abstract

The invention discloses a dust prevention and suppression agent. The dust prevention and suppression agent consists of the following components in parts by mass: 40-70 parts of attapulgite clay-xanthan gum-acrylic acid / acrylamide modified water-absorbent resin, 10-30 parts of modified mineral clay, 5-10 parts of sodium polyacrylate, 5-20 parts of modified natural celluloses, and 5-10 parts of mucopolysaccharide. The dust prevention and suppression agent is water-soluble powder, is toxic-free, harmless, safe and environmentally friendly, is diluted with water by 50-100 times when used, and is sprayed to the surfaces of coal dumps, dust and the like to form a hard shell, and the dust prevention and suppression rate is greater than or equal to 85%.

Description

1. Technical field [0001] The invention relates to a dust-proof and dust-suppressing agent, which belongs to the field of environmental pollution control. 2. Background technology [0002] With the development of science and economy, smog weather has appeared in many places in my country, and the problem of air pollution has become increasingly serious. At present, the main pollutants in the national air pollution are particulate matter, sulfur oxides, nitrogen oxides, carbon monoxide, and hydrocarbons. Inhalable particulate matter (PM 10 ) and inhalable pulmonary particulate matter (PM 2.5 ) and its fine particles have become the main factors restricting the air quality of cities in my country. [0003] In recent years, many achievements have been made in the research of dust suppressants at home and abroad. Regularly sprinkle water on mine stacking plants, muck transportation, construction sites, workshop dust, road construction, etc. to prevent dust. Fast, dust suppre...

AI Technical Summary

Problems solved by technology

[0003] In recent years, many achievements have been made in the research of dust suppressants at home and abroad. Regularly sprinkle water on mine stacking plants, muck transportation, construction sites, workshop dust, road construction, etc. to prevent dust. Fast, long dust suppression cycle, especially in winter road sprinkling is easy to cause traffic accidents

At present, spray dust suppression and ultrasonic dust suppression are still in the experimental stage, and the principle of dust suppression is to rely on their respective equipment to convert spray water into ultra-fine water mist, seal the dust source and remove dust, and the cost is relatively high.
