Description
Technical field
The present invention relates to combustion fumes processing technology field, more particularly to a kind of large-scale combustors dust separation device.
Background technology
The fuel garbage sorting of garbage incinerating power plant is not strict, and the oxidation of substantial amounts of flue dust, sulphur and nitrogen is produced during burning
The pernicious gases such as thing, dioxin, particularly dioxin, toxicity are very big, are 130 times, 900 times of arsenic of cyanide, there is " generation
The title of the poison of discipline ", IARC has been classified as mankind's one-level carcinogenic substance, and great wound is produced to health
Evil；In addition, burning power plant has focused largely on city and suburban area, low-altitude discharged is belonged to again, therefore, reduction waste incineration production
Raw dioxin concentration, continue its discharge, it is stable meet dioxin standard, be to closing weight to guaranteeing personal safety
Want.
The content of the invention
It is an object of the invention to provide a kind of large-scale combustors dust separation device, it can effectively understand that boiler combustion is produced
Raw flue dust and toxic and harmful gas.
To achieve the above object, technical scheme is as follows：
A kind of large-scale combustors dust separation device, including boiler, the smoke discharging pipe being connected with boiler, pond, the row
Smoke pipeline includes the first cleaning shaft being sequentially connected, the second cleaning shaft, the first purge pipe, the second purge pipe, in institute
The side for stating the first cleaning shaft and the second cleaning shaft is equipped with some hydraulic spray nozzles, and hydraulic spray nozzle is longitudinal along cleaning shaft
Arrangement, first cleaning shaft is connected with the second cleaning shaft with the pond；In first purge pipe and second
A gas purifier is equipped with purge pipe；The gas purifier includes 4 purification square tubes arranged in a straight line, described net
Change square tube be externally provided with one layer of heat preservation layer be used for by 4 purification square tube integral loops around, one layer of steel plate is additionally provided with outside the heat-insulation layer,
A flame-thrower nozzle is provided with a certain distance in the purification square tube outer purification square tube longitudinal direction；In first purge pipe
The port of export of gas purifier is additionally provided with a sealing plate in the arrival end of gas purifier and the second purge pipe, for by only
Change the gap seals between square tube and inner-walls of duct.
Preferably, the length of the purification square tube is 6 meters, and point three sections of progress welding are assembled, 2 meters every section.
Further, it is provided with a flame-thrower nozzle every 2 meters in the purification square tube outer purification square tube longitudinal direction.
Preferably, some supporting constructions are additionally provided between every two purifications square tube, are longitudinally equidistantly distributed along purification square tube.
Further, the supporting construction is support bar.
Compared with prior art, the device have the advantages that：In the present invention, the smoke exhaust that boiler combustion is produced is first
Through the first cleaning shaft and the second cleaning shaft, the hydraulic spray nozzle in purge pipe persistently sprays to the smoke exhaust in pipeline
Spill, can be effectively along the bulky grain flue dust in smoke exhaust, the sewage after sprinkling is discharged into pond, and then smoke exhaust is again through
One purge pipe and the second purge pipe, due to the barrier of sealing plate, waste gas can only enter from purification square tube, and flame-thrower nozzle is to guarantor
Space jet flames in warm layer, even flame other side's pipe outer wall heating, control flame temperature reach 800 DEG C, waste gas can be made
In the toxic and harmful gas such as dioxin decomposed, the tail gas of discharge is reached discharge standard, structure of the present invention uses steel
Material structure, can industrialized production, reduction production cost.
