Background technology

Adopt the application of shipment Unit Combination simplification mining technology, raising mine production efficiency have been played to positive effect.Because Underground Mine dump truck, scraper have motor-driven, flexible, multi-functional, economic dispatch characteristics, thereby be widely applied.Scraper, dump truck use Diesel engine to be used for underground work as power, although diesel equipment has the characteristics such as high efficiency, high power, the reliability high maintenance is convenient, but the tail gas Harmful ingredient content discharged in the diesel equipment use procedure is high, mainly contain soot PM, hydrocarbon HC, nitrogen oxide NOX, carbon monoxide CO and sulfur dioxide SO ₂.Particularly in the mine down-hole operating environment, various haulage vehicles and engineering machinery dealing are frequent, the restriction of mine ventilation condition in addition, the toxic and harmful severe overweight that these engineering equipments are discharged and can filling the air in whole operating environment, greatly endangered normally carrying out of the healthy of underground work personnel and construction, therefore, tool is controlled and purified to underground diesel machine equipment tail gas pollution is of great significance.

Normally descend the method for diesel equipment tail gas clean-up to have following several, emission controls by improving combustion, select the Diesel engine of low emission standard; External purification, adopt various post-treatment measures, installs various clarifiers additional in offgas duct; Recent years abroad is obtained large development in dry cleaning, in tail gas, the discharge capacity of toxic and harmful reduces to some extent, but the carbon black in oil smoke harm do not solved all the time at all, is badly in need of a kind of applicable effectively improvement purifier and technical scheme.

Summary of the invention

Technical problem to be solved of the present utility model is to provide a kind of multifunctional self-cleaned formula jet and induces the nebulization dust dirt sucking device, can solve preferably the difficult problem that underground diesel equipment oil smoke carbon black purifies, improve working environment at coal mines, be conducive to realize treating tail gas automation and intellectuality.

Solving the technical scheme that described technical problem of the present utility model takes is: under the liquid level of water tank that is filled with water, pipeline is set, device for cleaning pipeline is crossed the high-pressure fluid entrance that force (forcing) pump is connected to Venturi tube, the negative pressure entrance of Venturi tube is by the pipeline communication air intake, the outlet of Venturi tube is by the liquid level of pipeline communication water tank, and tank top arranges steam vent.

The high-pressure fluid inlet pressure of Venturi tube is 0.3～0.5MPa, is provided with the radar locating meter on the top of water tank, is provided with motor-driven valve at the pressurization delivery side of pump, and force (forcing) pump, motor-driven valve and radar locating score are not connected by data wire is corresponding with PLC.

The structure of Venturi tube is, the nozzle access connected with nut at an end of three-way pipe, and the other end two ends of three-way pipe become the bell-mouthed suction pipe of leading, and the right angle end of three-way pipe connects the pipeline of air intake, and the other end of leading suction pipe is connected to water tank wall.

Useful technique effect of the present utility model is: utilized the jet current principle suction of Venturi tube, when pressure 0.3～0.5MPa, working flow sprays at a high speed from nozzle, around it, forming negative pressure in air chamber, thereby the Tail Gas under suction well, around the high speed water column, wrap up in and taking aqueous vapor and rush in trunnion, the violent mixing of empty G&W is cut into microbubble in trunnion first half section, air is close to atomization within the second half section, air is soluble in water on this peak efficiency ground, after entering water tank, space increase pressure reduces, aqueous vapor is separated, air is discharged by steam vent, and carbon black granules enters water tank bottom with depositing in water.
