Abstract
The invention relates to a froth dedusting agent used in mine, belonging to the field of coal mining, and is suitable for coal mine underground mining dedusting, metallurgical mines mining dedusting and digging tunnel dedusting. The forth dedusting agent comprises 10 to 20 percent of dodecyl benzene sulfonate, 2 to 5 percent of succinic acid diester sulfonate, 4 to 8 percent of CDEA, 1 to 2 percent of addition agent and water. The mine dedusting agent has the advantages of high frothing percentage, long dedusting time, simple technical process and operation, no corrosion action or toxicity and side effect of the independent components and the solution and good dedusting effect, the dust laying rate to all dust can reach above 95 percent, and the dust laying rate to respirable dust can reach above 85 percent. The dedusting agent can improve the operating environment of underground working face effectively and has good effect on reducing dust hazard and realizing safe production.
Description
Technical field:
The invention belongs to the coal mining field, relate to a kind of underground mine use foam dedusting agent, can produce the foam of high stability, have higher efficiency of dust collection, can be used for the treating flour dust of coal mining, metal mine exploitation and tunnel digging etc.
Background technology
Coal Production is the key industry of industrial dust harm.Coal in China exploitation at present is based on pit mining.Because the down-hole coal excavation space is narrow and small, the job site is changeable, and ventilation effect is poor, so in the down-hole coal excavation, driving, reprinting, transportation, produces a large amount of dust, is not having under the situation of dust prevention, and the dust concentration of fully-mechanized mining working can reach 2500～3000mg/m
3, some colliery even up to 8000～10000mg/m
3More than.Dust concentration too high meeting in down-hole causes pneumoconiosis, and serious threat influences operating environment simultaneously to miner's personal safety and health.The dust prevention of mainly using in China mine at present has spray sprinkler, dust removal by ventilation and cleaner dedusting etc.The spray sprinkler water consumption is big especially, is not suitable for the water-deficient area; Dust removal by ventilation is influenced by wind speed, and dust removing effects is poor, and respirable dust is not had positive effect; Adopt the cleaner dedusting, it is less to be subjected to equipment to influence the dedusting scope.Because that foam dust-removing has is simple in structure, water consumption is few, to characteristics such as respirable dust efficiency of dust collection height, begin one's study abroad and be used widely since the fifties.China is about the research of chemical dust suppressant and start late, and does not also obtain deep research and good The field.
Summary of the invention:
The objective of the invention is to use the foam dedusting agent that foam dust-removing technology provides nontoxic, non-corrosiveness, high foaming rate, high stability for coal mining or other mining.
This foam dedusting agent raw material is industrial chemicals common, soluble in water both at home and abroad, and processing and preparing and construction method are simple.
The consisting of of foam dedusting agent for mine (wt%):
Dodecyl benzene sulfonate 10～20%
Succinic diester sulfonate 2～5%
Coconut oil diethanol amide 4～8%
CMS 0.1～0.5%
Formaldehyde 0.1～0.5%
Urea 1～2%
Water surplus
This foam dedusting agent is to be formed by surfactant compound, belong to the chemicals category, dodecyl benzene sulfonate wherein is meant neopelex, DBSA ammonium or neopelex, both mixtures of DBSA ammonium, and mixed proportion is not limit.Succinic diester sulfonate is the succinic diester sodium sulfonate.
The dust removal mechanism of this foam dedusting agent is: by add compound surfactant in water, reduce the surface tension of water, the contact angle of water and dust is diminished, make the aqueous solution have higher wetability and adhesiveness to dust, improve the affinity of water to dust; Foam has the characteristics of low-density, high surface area, utilize the huge cumulative volume of foam and the gross area, increase the contact-making surface and the adhesive force of foam solution and grit, increase dust and catch the chance that the dirt foam contacts, dust source is covered, cut off the propagation and the diffusion admittance of dust, thereby reach the depositing dust purpose.
Each raw material components of foam dedusting agent can also can be prepared into solution by proportioning and store by the component separate storage before enforcement.After the activated pre-molten processing of raw material components, mix to stir in proportion the foam dust-removing agent solution.For impelling each composition in water, to dissolve, should heat a little in the mixed process.
Foam dust-removing will be according to different dedusting agents of situation preparation performance such as dirt source requirements, down-hole situation difference, and the requirement of dedusting agent is also different.According to raw material sources situation and actual needs, can be processed into the concentrated foam agent by formula rate, thin up use again when using, solution concentration is diluted to 1.3～1.7% (wt%).
This foam dedusting agent pH value is 6.4, and is relatively neutral, avoided not causing secondary pollution to people's stimulation injury with to the chemical contamination of environment.This foam dedusting agent bubbles effective, and frothing percentage is higher, and foam has high stability, and the depositing dust time is long, and independent component and solution thereof do not have any corrosiveness and toxic and side effect.Water consumption is few, compares with the spray sprinkler depositing dust, and its water consumption reduces 3/4.Wide in the down-hole application scope, can be applicable to combine and adopt unit, driving unit, ribbon conveyer and dirt source than fixing place.
