Background technology
The heating system of existing pharmacy corporation generally all adopts coal firing boiler, due to a large amount of acid dusts can be produced in coal combustion process, in order to preventing pollution environment, generally lime is all adopted to process acid dust, therefore, pharmacy corporation all supportingly can have the lime feeding mechanism of boiler ash settling basin accordingly.
The structure of the lime feeding mechanism of existing boiler ash settling basin has generally comprised lime dense preparing tank and lime dilute preparing tank, the lower end of lime dense preparing tank is provided with the first carrier pipe be connected with lime dilute preparing tank, this first carrier pipe is provided with dehvery pump, the bottom of lime dilute preparing tank is connected with liquor calcis dropper, by this liquor calcis dropper, liquor calcis is added dropwise in boiler ash settling basin, processes.There is following problem in this mode:
In boiler ash settling basin, boiler Dust is often easy to sedimentation, and liquor calcis is added dropwise in boiler ash settling basin, needs to be dissolved in the water body in boiler ash settling basin, and just can carry out Pollutant Treatment, its reaction efficiency is lower, thus have impact on Pollutant Treatment efficiency.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of lime feeding mechanism that can improve a kind of boiler ash settling basin of Pollutant Treatment efficiency.
For achieving the above object, the technical solution of the utility model is a kind of lime feeding mechanism of boiler ash settling basin, include lime dense preparing tank and lime dilute preparing tank, the first agitator is provided with in lime dense preparing tank, the second agitator is provided with in lime dilute preparing tank, the lower end of lime dense preparing tank is provided with the first carrier pipe be connected with lime dilute preparing tank, this first carrier pipe is provided with dehvery pump, the bottom of lime dilute preparing tank is connected with liquor calcis output tube, described liquor calcis output tube is provided with force (forcing) pump, the lower end of this liquor calcis output tube is connected with swirl flow nozzle, this swirl flow nozzle includes annular nozzle seat and liquid-inlet pipe, the fluid inlet be connected with liquid-inlet pipe is provided with in described annular nozzle seat, on the inwall of this annular nozzle seat, circumference offers spiral slot, the liquid stream that the zygomorphy of this annular nozzle seat opposed helical groove is provided with circular cone shape disperses guide face, this spiral fluted degree of depth extends spirally direction along it and successively decreases gradually, and spiral fluted initiating terminal is connected with fluid inlet, the tail end of the inwall opposed helical groove of described annular nozzle seat is provided with tiltedly leads wall a pair for what toward two liquid streams of annular nozzle seat both sides, liquid was dispersed that guide face carries out water conservancy diversion, described spiral fluted tail end projection is provided with triangle flange, tiltedly leading wall for described a pair is arranged on two isometrical limits of this triangle flange, the back side gear of described triangle flange is located at the top of the fluid inlet of annular nozzle seat.
By this setting, pass through swirl flow nozzle, liquor calcis enters annular nozzle seat from this liquid-inlet pipe after force (forcing) pump pressurization, then liquid is guided by spiral slot circumference, and finally by tiltedly lead wall shunt and from the liquid stream of both sides disperse guide face become the conical surface disperse be shot out, liquid in liquid-inlet pipe can be become the torrent water curtain of flat cone curtain shape by this swirl flow nozzle, and the own of liquid in torrent water curtain also has helix angle speed, it is very even that this helix angle speed impels liquid dispersion to obtain, the current of this liming fully can contact with the contamination by dust thing in pond and react after entering into boiler ash settling basin, drastically increase reaction efficiency.
Further setting is that described the first carrier pipe is provided with control valve.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
