Background technology
In the parts of general boiler, superheater and economizer are made up of coiled pipe, but in the time of processing coiled pipe, tube interior can produce many dusts, dust.Because superheater and economizer are vitals in boiler operatiopn, need the water filling can overall operation, the accumulation of dust can affect the proper flow of water and steam, cause heat exchange bad, so needed to clear up dust, dust before parts finished product, and general manner of cleaning up adopts compressed air directly ash to be blown to towards the other end in pipe one end, dust, dust are directly discharged from from the other end of pipe, the dust being discharged from, the working environment that dust pollution is produced, and then staff's health is caused damage.
Summary of the invention
For the problems referred to above, the invention provides dust collecting installation in a kind of heating surface tubes in boilers, it is packaged in gathering-device dust, the dust of the pipeline inside for the treatment of deashing, can not pollute the working environment of producing, and then guarantee that staff's is healthy.
Dust collecting installation in a kind of heating surface tubes in boilers, its technical scheme is such: it comprises the cylindrical shell of upper opening, the bottom of described cylindrical shell is provided with base plate, it is characterized in that: the middle and upper part inner ring surface of the cylindrical shell of described upper opening is furnished with annulus location-plate, porous plate is supported on the upper surface of described annulus location-plate, described porous plate, cylindrical shell, the closed internal cavity that forms of base plate, in described internal cavity, water is housed, the center of described porous plate has center macropore, on the anchor ring of described porous plate, be evenly equipped with the aperture running through, sponge cover is loaded on the upper surface of described porous plate, straight tube runs through described center macropore from top to bottom, and stretch into below the water surface of described internal cavity, described straight tube is hollow tube, it also comprises flexible pipe, the port of export of described flexible pipe is set in the upper end import of described straight tube, the entrance point of described flexible pipe connects the port of export of the pipeline for the treatment of deashing.
It is further characterized in that: the bottom of described base plate has dewatering orifice, described in the stopple that discharges water plug screw is housed;
The lower surface of described annulus location-plate and the welding of the link position of described cylindrical shell are fastenedly connected;
Described straight tube runs through after the macropore of described center from top to bottom, the upper end anchor ring of its link position is fastening by welded seal;
Pressure ring press-fits in the upper end of described porous plate outer ring surface, and the outer wall of described pressure ring is close to the inwall of described cylindrical shell;
Described sponge is filled in the upper cavity of described porous plate, and the outer wall of described sponge is close to the top inner ring surface of described cylindrical shell.
Adopt after structure of the present invention, with compressed air by boiler superheater, dust in the pipeline of economizer wait deashing, dust passes through flexible pipe, straight tube is blown into below the water surface of the internal cavity that originally blows grey gathering-device, by the water seal effect in device, dust is incorporated in water, blow out for preventing flying dust, increase resistance by porous plate and carry out pressure balance, sponge is filtered unnecessary fine dusts, make the dust of the pipeline inside for the treatment of deashing, dust is packaged in gathering-device, can not pollute the working environment of producing, and then guarantee that staff's is healthy.
