Embodiment 1

[0024] 25% ammonium lignosulfonate, 5% ethylene glycol and water are compounded according to weight percentage to form ammonium lignosulfonate compound dustproof agent. Then put the prepared ammonium lignosulfonate compound dustproof agent in the container for dilution, and the diluted use concentration is 5%.

[0025] The diluted ammonium lignin sulfonate compound dustproof agent solution with a concentration of 5% is sprayed on the loose dust material through a high-pressure spray gun. The experimental results are as follows: figure 1 shown. It can be seen from the figure that spraying with ordinary water has poor effect, high moisture content, simple maintenance, but high cost. After adding common chemicals for spraying, the effect is good, the moisture content is significantly reduced, and the maintenance is simple, but the overall cost is high. Using the dustproof agent of the invention has good effect, lowest water content, simple maintenance and low cost.

Embodiment 2

[0028] 30% ammonium lignosulfonate, 10% ethylene glycol and water are compounded according to weight percentage to form ammonium lignosulfonate compound dustproof agent. Then place the prepared ammonium lignosulfonate compound dustproof agent in the container for dilution, and the diluted use concentration is 1%.

[0029] Use the diluted ammonium lignin sulfonate compound dustproof agent solution with a concentration of 1% to carry out dustproof treatment on loose dust materials by using a high-pressure spray water gun. The results are shown in Table 1 and Table 2 below through the detection of coal wind loss at a coal ore wharf in a certain port.

[0032] The above experiments are comparisons carried out on a single coal stack. According to the experimental results, after spraying the first few transfer points with the ammonium lignosulfonate compound dustproof agent solution, the subsequent ...

Embodiment 3

[0037] 60% ammonium lignosulfonate, 15% ethylene glycol and water are compounded according to weight percentage to form ammonium lignosulfonate compound dustproof agent. Then place the prepared ammonium lignosulfonate compound dustproof agent in the container for dilution, and the diluted use concentration is 0.1%.

[0038] The diluted ammonium lignin sulfonate compound dustproof agent solution with a concentration of 0.1% was used for dustproof treatment and detection on the road surface of a mining area through a high-pressure water spray gun, and the results were as follows: image 3 shown.

[0039] The experimental results show that after spraying the ammonium lignosulfonate compound dustproof agent solution on the road surface, the dustproof water and power consumption are reduced by 30-50%, thereby reducing the dustproof cost and improving the environmental quality.

Abstract

The invention discloses an ammonium lignin sulphonate compound dust-proof agent and an application thereof. The ammonium lignin sulphonate compound dust-proof agent is prepared by compounding 25%-75% of ammonium lignin sulphonate, 5-15% of ethylene glycol and the balance of water by weight. The working concentration of the ammonium lignin sulphonate compound dust-proof agent is 0.1-10%. The using steps of the ammonium lignin sulphonate compound dust-proof agent are as follows: (1) preparing the ammonium lignin sulphonate compound dust-proof agent; (2) diluting the prepared ammonium lignin sulphonate compound dust-proof agent till meeting the working concentration; (3) spraying the diluted ammonium lignin sulphonate compound dust-proof agent on the surfaces of dust material particles through a high-pressure spray gun. The dust removal effect of the ammonium lignin sulphonate compound dust-proof agent disclosed by the invention can reach above 80%; as the air loss is obviously reduced in a dust source conveying process, the air quality of a dust source location is greatly improved, and the economic loss is reduced.

Description

technical field [0001] The invention relates to a dustproof agent, in particular to an ammonium lignosulfonate compound dustproof agent and an application method thereof. Background technique [0002] At present, among various types of air pollution, dust pollution is becoming more and more serious with the deterioration of the environment. It mainly comes from the process of grinding, crushing, stacking, loading and unloading of loose dust materials. One of the most direct causes of atmospheric particle pollution in my country's coastal cities is the diffusion and migration of coal and ore wharf dust pollutants in the atmospheric environment, and the dust source diffusion during the loading and unloading of coal and ore often constitutes The main body of port dust pollution. At the same time, during the loading, unloading and transportation of coal after mining, the fugitive loss of coal accounts for 0.3% of the total coal transportation. According to the current annual c...
