Description
Technical field
The utility model relates to carbon roasting furnace bitumen flue gas pollution abatement equipment and technology, belongs 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, all be quirk, discharge jointly outside the roaster, then through the waste gas pollution control and treatment system through building by laying bricks or stones, after deviating from harmful substance, through smoke stack emission based on bitumen flue gas.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 purpose of this utility model is to overcome existing bitumen flue gas and administers technical defective, realizes 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 utility model is achieved through 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 the utility model device 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 utility model.
The utility model 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.
