Problems solved by technology

[0004] At present, the research and development of coal dust pollution control agent technology is relatively scattered, the level is uneven, and the variety and efficacy are relatively single; those that play a role in dust fixation cannot simultaneously play a good role in flame retardancy, and vice versa
At present, no systematic research has been done on coal dust pollution control agent technology, and there is no industrial application
There is no new dust-fixing pollution control agent technology that can not only play a flame-retardant role, but also play a good role in dust fixation

Abstract

The invention relates to a preparation method of a control agent for coal dust pollution. The preparation method adopts the components with the following weight portions: 1 to 3 portions of polyvinyl alcohol (PVA), 2 to 3 portions of industrial starch, 1 to 1.5 portions of glutinous rice flour, 85 to 95 portions of water, 1 to 2 portions of polyoxyethylene nonylphenol ether and 1 to 2 portions of sodium humate. The control agent is prepared by mixing and evenly stirring the materials. The sodium humate contains 40 percent to 60 percent of humic acid and 10 percent to 20 percent of natrium. The control agent is characterized by low cost, wide material source, stable performance, wide application, innocuity and harmlessness, low corrosion rate, no odor and the like, as well as high inhibition rate, remarkable dust suppression effect, good frost resistance performance and the like. The technique that blending the control agent and spraying the control agent on the surface are combined is adopted in large-sized coal mines, ports and coal storage in China, thus realizing dust control and flame retardancy during production, storing and transporting processes of coals.

Description

Technical field [0001] The invention relates to a preparation method of a coal dust pollution control agent. Background technique [0002] Particulate matter pollution and dust pollution are serious environmental pollution problems faced by the majority of cities in my country, especially the production of raw coal in my country reached 2.5 billion tons in 2008, and more than 80% of it must pass through the storage and transportation system to reach users. These raw coals are spontaneously combusted during production, storage and transportation. The loss of sprinkling and dust is about 1% in preliminary statistics. The annual loss of coal exceeds 20 million tons, which not only wastes energy, but also seriously pollutes the environment. [0003] Taking a 10,000-ton coal storage yard as an example, the annual loss of pulverized coal due to wind is 100-200 tons, and the loss is nearly 100,000 yuan. The coal yard in Shijiazhuang area has an annual turnover of nearly 100 million tons...
