The utility model content
The purpose of this utility model is to provide a kind of can realize the stable pulvis particle transport device of carrying of pulvis granule materials.
The purpose of this utility model is achieved through the following technical solutions: a kind of pulvis particle transport device, comprise powder-storage bin, the granule materials of described powder-storage bin links to each other by the top inlet end of discharge duct with the winding-up jar, the bottom granule materials exit end of winding-up jar links to each other with the pulvis delivery pipe by the powder control cock, it is characterized in that: be connected with winding-up jar pressurising pipe and winding-up jar relief tube on the winding-up jar, in the winding-up jar injection tank pressure table is installed, the line pressure table is installed on the pulvis delivery pipe.
Further, the bottom of described pulvis delivery pipe is provided with and carries the ascending pipe blowdown pipe.
Further, a described winding-up jar pressurising pipe is provided with pressurising pipe control cock, according to the signal of injection tank pressure table and line pressure table feedback pressurising pipe control cock is regulated.
Further, described a kind of pulvis particle transport device, described powder control cock is a kind of valve of variable throat.
Principle of work of the present utility model is as follows: at first a winding-up jar blowdown valve is in open state, open discharge valve, material in the powder-storage bin enters the winding-up jar through discharge duct, when the material in the winding-up jar reaches the appointment material level, close discharge valve and blowdown valve, open the equalizer valve in the pressurising pipeline, pressure controller is regulated a winding-up jar equalizer valve according to the force value of injection tank pressure table and pulvis line pressure table output, makes pressure in the winding-up jar less times greater than (about 0.1～1kg/cm
2) the pulvis line pressure.After pressure satisfies specified requirements, open the powder control cock a winding-up jar interior pulvis is flowed out from the bottom, open delivery pipe ascent stage blowdown pipe valve simultaneously, pulvis is exported via spray gun at last.The aperture of the powder control cock by regulating the outlet of winding-up pot bottom is to guarantee to enter pulvis in the winding-up pipeline in the safe range that thin strength is carried.
The utility model not only can effectively utilize coke oven flue gas waste heat and ascending pipe coal gas waste heat to realize the drying of coal simultaneously, also reduced the ammoniacal liquor consumption that is used for the raw coke oven gas cooling in the bridge tube simultaneously, provide an effective way for further realizing the coal chemical enterprise synthetic energy-saving discharge-reducing.
