Simultaneously because substantial amounts of heat is included in the tail gas that phosphorus stove is produced, if directly discharge will necessarily aggravate in an atmosphere
Greenhouse effect is, it is necessary to make full use of this partial tail gas waste heat to reduce production, the bigger productivity effect of acquisition.Yellow phosphorus exhaust gas
Boiler technology and its system complete set of equipments are phosphorus production enterprises increasingly competitive, under entry criteria increasingly strict situation
Seek one of energy-saving and emission-reduction, the important technology on road of consumption reduction.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the utility model provides the tail gas reality that a kind of effective utilization phosphorus stove is produced
Now preheating is recycled, and is reached that energy-saving and emission-reduction improve production environment, boiler water is heated using waste heat, so as to reduce boiler
The reduction of fuel, realizes double down phosphorus furnace exhaust gas purification recovery device.
The utility model solves the technical scheme that its technical problem used：A kind of phosphorus furnace exhaust gas purification recovery device,
Including filtering sedimentation pipe, blower fan, scrubber tower, combustion chamber, recuperative furnace and the blast pipe being connected in turn, it is heavy that blower fan is located at filtering
Between drop pipe and scrubber tower；
Filtering sedimentation pipe is vertically installed above phosphorus stove, and one group of inclined tube, two are set apart from bottom symmetrical on filtering sedimentation pipe
Root inclined tube is in splayed structure, and inclined tube, which is extend into phosphorus stove two ends access tail gas, filtering sedimentation pipe, to be located above inclined tube junction
Filter is set；
Filtering sedimentation pipe is connected with scrubber tower, and scrubber tower and combustion chamber, combustion chamber set a micro Gas Pipe,
Light tail gas；
Combustion chamber is linked into recuperative furnace, the dividing plate mutually staggered is set in recuperative furnace, it is ensured that tail gas is on the road of recuperative furnace
Line is S-shaped, is vertically arranged steam pipe between adjacent two pieces of dividing plates, steam pipe is linked into drum in parallel way, steam pipe bottom
Portion is provided with tubule, tubule access cold water, and the water inlet pipe of tubule is entered vertically into heat exchange furnace bottom from recuperative furnace outlet one end, most
Whole recuperative furnace is linked into blast pipe.
Four inclined tubes are set on the filtering sedimentation pipe, in crossing distribution.So the tail gas of phosphorus stove is not from bottom row
Go out, but from the side wall discharge close to top, reduce the dust content in tail gas, the processing for so reducing dust in tail gas is difficult
Degree, has largely been stayed in phosphorus stove.
The filtering sedimentation pipe distance from bottom phosphorus stove 15-50cm, and bottom can open.Filtering is entered by inclined tube heavy
The tail gas of drop pipe is fallen by filter screen filtration, so as to fall on bottom, ash that can be to clean out accumulation in time is opened in such bottom
Dirt.
The water inlet pipe of the tubule is located at recuperative furnace gas outlet netted in filtering.This ensure that tail gas exchanges heat in discharge
When stove, heat is predominantly absorbed as far as possible, the temperature of discharge is reduced, while waste heat can be heated somewhat in tubule
Water, custom is ejected into steam pipe, can be heated to form vapor or hot water.
The utility model has the advantages that：It is easy that top discharge tail gas is solved well using the design of inclined tube
Substantial amounts of dust is taken away, the dust content of tail gas is reduced, reduces intractability, while tail gas is entered vertically by writing
Filter sedimentation pipe when, be forced filtering, dust by filtered dropped into filtering sedimentation pipe bottom accumulated, so reduce tail
Dust increases the service life for the destruction of post facility in gas.It is not the water circulation using routine in recuperative furnace, and uses
The tubule of separate type is sprayed onto, and can so obtain more preferable vapor, it is ensured that the efficiency of heat exchange.
