Abstract
The utility model discloses a hot blast heater for drying white carbon black of black tail gas of burned carbon. The hot blast heater comprises a carbon black tail gas burner, an air distribution room is arranged above a burning room of the carbon black tail gas burner, and a heat exchanger is arranged at the tail end of the air distribution room. A hot air outlet communicated with a white carbon black drying tower is arranged on one sides of the heat exchanger, a heat exchange air blower is arranged above the other side of the heat exchanger, an air pre-heater and a smoke induced draft fan are sequentially arranged at the outlet end of the heat exchanger, an input pipe of the air pre-heater is communicated with the combustion fan, and the air pre-heater sends pre-heated carbon black to the carbon black tail gas burner through a convey pipe. The hot blast heater is provided with the carbon black tail gas burner and the heat exchanger, heat generated by tail gas burning is conveyed to the drying tower to dry the white carbon black through the hot air outlet after heat exchange is carried out on the heat, and energy is saved.
Description
Technical field
The utility model relates to a kind of hot-blast stove device that is applicable to provide the burning carbon black industry tail gas of hot blast to the white carbon black production drying process in white carbon black production.
Background technology
At present, the hot-blast stove that white carbon black production is used is all coal-fired or the hot-blast stove of combustion natural gas, and production cost is high.Carbon black tail gas has certain calorific value, contains the combustion composition in tail gas and is mainly carbon monoxide, and dust content is large.But present carbon black tail gas is emptying wastes all generally, can not be utilized effectively, and can contaminated air.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of white carbon drying hot-blast stove of recoverable carbon black tail gas.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the dry hot-blast stove of using of a kind of white carbon of the carbon black tail gas that burns, its key technology is: comprise a carbon black tail gas combustor, be provided with distribution plenum above the combustion chamber of carbon black tail gas combustor, be provided with heat exchanger at the end of distribution plenum; Be provided with in heat exchanger one side the hot-blast outlet that is connected with the white carbon drying tower, the opposite side top is provided with the heat exchange air blast, the port of export at heat exchanger is provided with air preheater and smoke induced draught fan successively, air preheater is communicated with combustion fan by intake line, and the carbon black tail gas of described air preheater after conveyance conduit is with preheating delivered to the carbon black tail gas combustor.
The beneficial effect that adopts technique scheme to produce is: the utility model is provided with carbon black tail gas combustor and heat exchanger, and the heat that produces after exhaust combustion is transported to drying tower by the hot-blast outlet that arranges white carbon is carried out drying after heat exchange; Outlet at heat exchanger is provided with air preheater, enters the carbon black combustor by the air after combustion fan after preheating and carries out air distribution, and the partially recycled amount of residual heat will of flue gas has been saved the energy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein, 1, carbon black tail gas combustor; 2, combustion chamber; 3, distribution plenum; 4, heat exchanger; 5, air preheater; 6, smoke induced draught fan; 7, heat exchange air blast; 8, hot-blast outlet.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to accompanying drawing 1, the utility model comprises a carbon black tail gas combustor 1, is provided with distribution plenum 3 above the combustion chamber 2 of carbon black tail gas combustor 1, is provided with heat exchanger 4 at the end of distribution plenum 3; Be provided with the hot-blast outlet 8 that is connected with the white carbon drying tower in heat exchanger 4 one sides, the opposite side top is provided with heat exchange air blast 7, the port of export at heat exchanger 4 is provided with air preheater 5 and smoke induced draught fan 6 successively, air preheater 5 is communicated with combustion fan 9 by intake line, and the carbon black tail gas of described air preheater 5 after conveyance conduit is with preheating delivered to carbon black tail gas combustor 1.
After adopting the utility model, carbon black tail gas is by carbon black tail gas combustor 1, enter the combustor rear flame that fully burns in certain air and tail gas ratio and enter combustion chamber 2, hot blast enters into heat exchanger 4 by air compartment 3 and carries out heat exchange, adopt the shell side flue gas of negative pressure work and the tube side air of malleation work to carry out heat exchange, guaranteed the cleanliness factor of heat exchange air, the pure air after heat exchange enters by hot-blast outlet 8 product drying that drying tower carries out white carbon.Flue gas is discharged by smoke induced draught fan 6, in the outlet of heat exchanger 4, air preheater 5 is installed, and the combustion air of combustion fan 9 enters into carbon black tail gas combustor 1 after by air preheater 5 preheatings and carries out air distribution.The utility model uses industrial carbon black tail gas to do fuel to carry out heat exchange by heat exchanger white carbon black product is carried out drying, guaranteed that namely white carbon black product has not been reduced again production cost by the contaminating impurity in carbon black tail gas, compared the burning carbon black tail gas with the manufacturer of similar gas-firing and can save production cost approximately 1/4.
