Embodiment 1

[0038] A low-cost coal dust suppressant comprises the following components by weight: 1.5 parts of powder and 98.5 parts of water.

[0039] Described pulvis is calculated by weight component:

[0040]

Embodiment 2

[0042] A low-cost coal dust suppressant comprises the following components by weight: 1 part of powder and 99 parts of water.

[0043] Described pulvis is calculated by weight component:

[0044]

[0045] In the second aspect of the embodiment of the present application, a method for preparing a low-cost coal dust suppressant is also provided. The method for preparing the low-cost coal dust suppressant is used to prepare the low-cost coal dust suppressant provided in the first aspect of the embodiment of the application. Dust agent, described method comprises the following steps:

[0046] At room temperature, add 40-50 parts of sodium carboxymethylcellulose, 0-0.01 parts of surfactant, 0.8-1 part of corrosion inhibitor, 0.5-1 part of polyacrylamide, 20-30 parts of Sodium sulfate, 20-30 parts of sodium tetraborate, and fully stirred for 30 minutes to obtain a powder.

[0047] Add 0.8-1.5 parts of the powder into 98.5-99.2 parts of water according to the ratio of parts by w...

Abstract

The invention discloses a low-cost coal dust suppressant and a preparation method thereof. The low-cost coal dust suppressant comprises sodium carboxymethyl cellulose, sodium tetraborate, sodium sulfate, a corrosion inhibitor, polyacrylamide, a surfactant and water. The preparation method of the coal dust suppressant comprises the following steps: sequentially adding the sodium carboxymethyl cellulose, the surfactant, the corrosion inhibitor, the polyacrylamide, the sodium sulfate and the sodium tetraborate, and fully conducting stirring for 30 minutes to obtain powder; and adding the powder into water while stirring, and continuously conducting stirring for 20-30 minutes after the powder is completely added. According to the low-cost coal dust suppressant and the preparation method thereof provided by the invention, sodium tetraborate and sodium sulfate are added, so that the use of sodium carboxymethyl cellulose is reduced to a great extent, and the preparation cost of the dust suppressant is reduced.

Description

technical field [0001] The application relates to the field of environmental protection, in particular to a low-cost coal dust suppressant and a preparation method thereof. Background technique [0002] Coal dust generated during coal transportation is a major source of dust pollution. In my country, coal transportation is carried by gondola cars. During the transportation process, due to factors such as bumps, wind, and pressure differences, coal particles will cause dust, which will pollute the environment. [0003] For coal dust pollution, the traditional countermeasures are to cover coal trucks with tarpaulins or spray water on coal trucks. These methods have solved the problem of coal dust flying in the process of pulling coal to a certain extent, but there are still some deficiencies. For example, the tarpaulin used to cover the surface of the coal car may be blown apart or broken by the wind during the operation of the vehicle. For another example, when spraying wat...
