Description
Technical field
Incinerator is purified the present invention relates to one kind, more particularly to a kind of asphalt smoke gas purifying being used in carbon industry administers asphalt smoke gas purifying incinerator.
Background technology
In aluminum electrolysis industry, electrolytic aluminum anode uses carbon material, in the production process of carbon annode, the coal tar pitch of modification is widely used as bonding agent, and this is due to that coal tar pitch has the advantages that aboundresources, cheap, phosphorus content are high, can increase product volume density and mechanical strength.But can produce bitumen flue gas when pitch heating and bituminous substance combustion, the complicated component of bitumen flue gas contains substantial amounts of organic pollution, main component is alkane and benezene material, and glance coal can have a strong impact on growing for animals and plants, while also being polluted to atmospheric environment.Therefore, in aluminum electrolysis industry, the bitumen flue gas of generation has to pass through purified treatment.
For the purified treatment of bitumen flue gas, according to the characteristic of nuisance, through frequently with processing method be absorption method and burning method, the shortcoming of absorption method is that treatment effect is not special ideal, and burning method is relatively good for the treatment effect of nuisance.The principle of burning method is that, by organic exhaust gas heat resolve generation carbon dioxide and water in combustion chamber, the high-temperature gas of generation flows through special ceramic heat storage body, makes ceramic body heating accumulation of heat, the organic exhaust gas subsequently entered for preheating.Burning method has the advantages that waste gas decomposition efficiency height, heat recovery rate are high, but the high cost and device structure of ceramic heat storage body complexity make it that the cost of investment of current burning method is huge, simultaneously because existing burning facility is at least divided into more than two compartments, the turnover of gas is required for the control of valve, causes the problems such as complicated control of equipment, maintenance inconvenience.
The content of the invention
In order to solve the above-mentioned technical problem the invention provides a kind of asphalt smoke gas purifying incinerator, purpose is in order to purify the bitumen flue gas or other organic exhaust gas that are produced in carbon industry, high pollution organic substance combustion decomposition in waste gas is produced into free of contamination gas, and the condensation problem of bitumen flue gas in the duct in anode production is solved, reduce the discharge of pollutant.
To reach above-mentioned purpose, a kind of asphalt smoke gas purifying incinerator of the present invention, including heat-exchanger rig and incinerator, the heat smoke outlet of heat-exchanger rig is connected by gas-guide pipeline with the air inlet of incinerator, heat exchanger tube is provided with heat-exchanger rig, the purification gas entrance of heat exchanger tube is connected by pipeline with the purified gas outlet of incinerator, and the offgas outlet of heat exchanger tube stretches out heat-exchanger rig, and heat-exchanger rig is provided with pitch cold flue gas entrance.
The heat smoke outlet of heat-exchanger rig is located at the top of heat-exchanger rig.
The pitch cold flue gas entrance of heat-exchanger rig is located at the bottom of heat-exchanger rig.
The air inlet of heat exchanger tube is located at the bottom of heat-exchanger rig.
The offgas outlet of heat exchanger tube is located at the top of heat-exchanger rig.
Burner is provided with incinerator.
Purified gas outlet is located at the bottom of incinerator.
Heat exchanger tube is vertically arranged.
Advantages of the present invention effect：Heat exchange is carried out by the bitumen flue gas of the high-temperature flue gas after burning and systematic collection, preheating and heating to flue gas is realized；By using burner, realize and uncontaminated gases are produced to bitumen flue gas or organic exhaust gas combustion decomposition；With control mode it is easy, invest small, long lifespan, easy to maintenance, drag losses it is small, simple to operation, it is practical the features such as.The pollution of bitumen flue gas can effectively be handled.Ensure the green anode product workshop pollutant emission index of carbon, with important economy and social value.
