Embodiment 1

[0013] This dust-removing foam generator includes the following components in weight percentage: 0.3% sodium dioctyl sulfosuccinate, 0.1% sodium dioctyl sulfosuccinate, 0.1% nonylphenol polyoxyethylene ether, coconut oil diethanol Amide 0.1%, triethanolamine 0.1%, fatty acid polyoxyethylene ester 0.02%, pentaerythritol oleate 0.1%, and the balance is water.

[0014] For on-site application, it needs to be configured as an aqueous solution, the concentration of the solution is diluted to 1% (wt%), it is added to the foam generator, and the generated foam is transported to the cutting head of the roadheader to cover the cutting head, and the cutting head is placed to generate The dust diffuses outwards and makes it settle. The specific on-site dust concentration measurement results are shown in Table 1 below:

[0015]

[0016] It can be seen from Table 1 that the formula has a good dust reduction effect, the dust reduction rate of the whole dust can reach 95.78%, and the dust...

Embodiment 2

[0018] This dust-removing foam generator includes the following components in weight percentage: 0.5% sodium dioctyl sulfoplatinate, 1% sodium dioctyl sulfosuccinate, 1% nonylphenol polyoxyethylene ether, coconut oil diethanol Amide 0.5%, triethanolamine 0.5%, fatty acid polyoxyethylene ester 0.1%, pentaerythritol oleate 0.2%, and the balance is water.

[0019] For on-site application, it needs to be configured as an aqueous solution, the concentration of the solution is diluted to 0.2% (wt%), it is added to the foam generator, and the generated foam is transported to the vicinity of the cutting head of the roadheader to cover the cutting head, and the cutting head is placed to generate The dust diffuses outwards and makes it settle. The specific on-site dust concentration measurement results are shown in Table 2 below:

[0020]

[0021] It can be seen from Table 2 that the formula has a good dust reduction effect, the dust reduction rate of the whole dust can reach 96.19%,...

Abstract

The invention discloses a dust-removal foaming agent and relates to the technical field of environment protection and dedusting. The dust-removal foaming agent is composed of 0.3% to 0.5% by weight of sodium dioctylsulfoplatinate, 0.1% to 1% by weight of sodium dioctylsulfosuccinate, 0.1% to 1% by weight of nonylphenol polyoxyethylene ether, 0.1% to 0.5% by weight of coconut oil diethanolamide, 0.1% to 0.5% by weight of triethanolamine and the balance of water. The dust-removal foaming agent can completely coat, wet and settle dust produced by a dust resource, improve dust removal efficiency and solve the problems of high investment, large water consumption and easy secondary pollution of water.

Description

technical field [0001] The invention relates to the technical field of environmental protection dust removal, in particular to a dust removal foam generating agent for mining. Background technique [0002] Mine dust is mainly composed of ore particles and other powders, and is divided into dry dust and wet dust in state. During mining and subsequent processing and production, dust generation is mainly concentrated in the drilling and blasting process, crushing, screening and belt transmission, transportation, and reloading processes. A complete mine processing production line needs to go through processes such as crushing, screening, grinding, transportation, and aggregates. Each process, accompanied by the fragmentation and movement of ore, will gradually separate fine particles, resulting in more and more Much dust. [0003] In the technical field of mine dust removal, there are solutions such as water spray dust removal, vacuum dust removal, filter dust removal, high-vo...
