Environment-friendly bulk coal overlapping restrainer and method of producing the same

Abstract

The invention discloses an environment-friendly type separate coal covering inhibitor, which comprises the following components in weight percentage: 0.05 to 2.00 percent of carboxymethyl cellulose, 0.50 to 2.50 percent of glycerin, and the balance being water. The invention also provides a method for preparing the environment-friendly type separate coal covering inhibitor. The preparation method comprises the followings steps: a reaction kettle is added with water accounting for 80 percent of total water quantity, added with the carboxymethyl cellulose, started to be stirred, added with the glycerin when the carboxymethyl cellulose is completely dissolved, evenly stirred, added with the remained water accounting for 20 percent of total water quantity, and evenly stirred so as to obtain the finished product. The inhibitor has reasonable formula and is easy to purchase; because the materials are organic matters, the inhibitor does not affect the fuel value of coal after spraying; moreover, the inhibitor also has the advantages of low cost, convenient use, obvious dustlaying and loss prevention effects, obvious economic and ecological benefits, simple production process, no secondary pollution during processing and using, safe use and no toxic and side effects.

Description

technical field [0001] The invention relates to a coal dust prevention inhibitor and a preparation method thereof, in particular to an environment-friendly loose coal covering inhibitor and a preparation method thereof. Background technique [0002] For a long time, coal, as a basic energy source, has always occupied a dominant position in my country's energy production and consumption structure. According to the prediction of relevant experts, by 2050, the proportion of coal in my country's primary energy will still occupy more than 50%. During the storage and transportation of coal, a large amount of coal dust will be generated, which will not only cause coal loss, waste natural resources, but also cause serious pollution to the environment. In addition, for coal piles, dust may also cause safety accidents. In the open-air coal storage plants of some thermal power plants, due to the flying coal dust, the heating pipes, cables, etc. can cause fires due to the spontaneous ...

Problems solved by technology

The wetting agent is mainly composed of surfactants and some inorganic salts and halides; the inorganic binders mainly include halides, calcium oxide, coal ash, soil, clay, gypsum, kaolin, acid, etc., and the organic binders mainly include crude oil, olive Oil waste residue, petroleum residue oil, lignin derivatives, cinder oil, asphalt, paraffin, polymer, etc.; these dust suppressants are either complicated in processing technology, high in cost, or have certain toxic side effects and corrosion Therefore, in order to save precious coal resources and reduce environmental pollution, it is imperative to study cheap and easy-to-obtain loose coal covering dust suppressants without secondary pollution
