Description
Technical field
The present invention relates to carbon roasting furnace bitumen flue gas pollution abatement equipment and technology, belong to the carbon industry environmental technology field.
Background technology
The plain green billet of charcoal has only through the roaster roasting, and after outwards excluding low-volatile in the binding agent (pitch), just has mechanical strength, electric conductivity and thermal conductivity.Therefore, roasting is an indispensable important process process during carbon product is produced; Simultaneously, it is inevitable that carbon roasting furnace produces bitumen flue gas.
The plain factory of charcoal generally adopts circular furnace (tunnel cave) or down-draft furnace as roaster both at home and abroad.As everyone knows, when common carbon product calcining furnace is produced, the bitumen flue gas that is produced during the plain green billet roasting of the charcoal of charging in the cavity, do not realize separating with the combustion product gases that produces in the roaster burner hearth combustion process, it all is quirk through building by laying bricks or stones, the common roaster of discharging is outward then through the waste gas pollution control and treatment system, deviate from harmful substance based on bitumen flue gas after, through smoke stack emission.According to relevant creation data statistics, institute's bituminous low-volatile is 100～500mg/Nm in this waste gas
3, in per in other words combustion product gases more than 2600 kilograms, the pitch low-volatile about 1 kilogram is arranged.The quantity of combustion product gases is considerably beyond the quantity of bitumen flue gas.In addition, the tar particle in the bitumen flue gas is the volatilization condensate, and its particle diameter is about 0.1～1 μ m, have extremely strong adhesiveness, resistance is big during high temperature, therefore, no matter adopt what method, itself just be difficult to it is removed from gaseous state, in addition be mingled in a large amount of combustion product gases again.
Summary of the invention
The objective of the invention is to overcome existing bitumen flue gas and administer technical defective, realize the bitumen flue gas of carbon roasting furnace and separating of combustion product gases.On common carbon roasting furnace, generation time is long, quantity few (for combustion product gases), pollute the heaviest, administer the most difficult bitumen flue gas, collect separately, gather, administer.And, discharge after bitumen flue gas being delivered to the burner hearth high temperature incineration of roaster according to charcoal ink factory's furniture body situation; Behind the burner hearth high temperature incineration, discharge again after perhaps bitumen flue gas being recycled.
The present invention is achieved by the following technical solutions:
1, on any one face of each charging cavity of roaster or on a plurality of, install at least one, have ventilative (as partly cuing open) the bitumen flue gas gatherer of one side at least, and connect with the bitumen flue gas gatherer, at least one bitumen flue gas convergence device.The plain green billet of charcoal in the charging cavity, the pitch low-volatile (bitumen flue gas) of Chan Shenging at a certain temperature, through gatherer collect, convergence device converges, and through be connected with the bitumen flue gas convergence device, at least one arm of drawing that passes this charging cavity sealing surface, it is drawn this charging cavity.
Being installed in bitumen flue gas gatherer, the bitumen flue gas convergence device of a charging in the cavity, passing the arm of drawing of cavity sealing surface, is the passage that the bitumen flue gas of this charging cavity generation is collected, gathered and draws.
2, the bitumen flue gas that produces in cavity of each charging, through drawing after arm draws seal chamber of this cavity, converge and enter be installed in roaster outer, at least one feeder.Thereby the bitumen flue gas of carbon roasting furnace generation and separating of combustion product gases have been realized.
3, on the external pipeline, connect at least one flow tank, explosion-proof apparatus, blower fan, valve, be installed in the injector of burner hearth.Blower fan with valve regulated, control bitumen flue gas gatherer, bitumen flue gas convergence device, draw bitumen flue gas flow and pressure in arm, feeder, external pipeline and the device that is connected thereof, keep apparatus of the present invention and normally move; Flow tank has the dedusting cooling performance, and explosion-proof apparatus is a safety device, and injector has the fuel burner nozzle feature, and the burner hearth of roaster is bitumen flue gas high temperature incineration place.
4, on 3 described external pipelines, can also connect the bitumen flue gas treatment system, this system is meant with firing method electric fishing method, absorption method, absorption process etc. and reclaims the device of administering bitumen flue gas, or various waste gas pollution control and treatment equipment and combination thereof.Be according to the concrete condition setting of the plain manufacturer of charcoal in the present invention, but be not the essential device that is provided with.
The present invention bitumen flue gas and combustion product gases collected, that gather, draw, converge have been realized separating.Because of its concentration height, quantity are few, so administer easily; Apparatus structure is simple, the dismounting maintenance is easy, equipment investment is little, operating cost is low, realize the bitumen flue gas recycling easily.Finally through the burner hearth high temperature incineration of roaster, pollution control is thorough for bitumen flue gas.Meet " major polluting sources keypoint treatment " and the principle of " comprehensive utilization " in the environment protection treating.

The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present invention is further specified for example, but be not limited to given embodiment of embodiment or implementation result.
In roaster filled each charging cavity 10 of the plain green billet 11 of charcoal, one deck inserts 12 tiled on the plain green billet 11 of charcoal earlier.The ventilative face 2 of bitumen flue gas gatherer 1 is downward, lie in and fill on the bed of material 12.All bitumen flue gas gatherers insert in the socket joint hole 6 of bitumen flue gas convergence device 5 after 1 bell-and-spigot pipe 3 on it is coupled to each other, and with fastener 4 gatherer 1 are fixed with convergence device 5.Then between device, and look technological requirement on device, the one deck that tiles is again filled the bed of material.Draw arm 7 pass the charging cavity sealing surface 8, converge with bitumen flue gas feeder 9.
Under the high-temperature roasting state, pitch low-volatile in each charging cavity of roaster in the plain green billet of charcoal, through processes such as evaporation, thermal crackings, with gaseous state enter bitumen flue gas gatherer 1, bitumen flue gas convergence device 5, draw arm 7, feeder 9, behind flow tank 14 dedusting coolings, explosion-proof apparatus 15, bitumen recovery device 16 recovery section pitches, through at least one injector 17, enter at least one roaster burner hearth 18, make the bitumen flue gas of failing to reclaim realize high temperature incineration.Blower fan 20 and valve 19, the flow and the pressure of the bitumen flue gas in adjusting, control pipeline and the jockey thereof.Through the high-temp combustion harmless waste gas that bitumen flue gas produced completely, together discharge through chimney 21 with the fuel combustion flue gas.
