Technical Field

The utility model belongs to the technical field of the environmental protection technique and specifically relates to indicate an active carbon industrial kiln flue gas white system that disappears.

Background

With the increasing environmental protection requirements of China, the flue gas generated in the manufacturing process of the activated carbon can be discharged into the atmosphere after being treated by a desulphurization device. The flue gas at the outlet of the wet desulphurization device is generally saturated wet flue gas at the temperature of 45-55 ℃, is mixed with low-temperature air in the environment after being discharged from a chimney, and carries liquid drops formed by partial condensation, so that the flue gas cannot be rapidly dissipated, particularly, water vapor is condensed and separated out in the mixing process or in the time period of haze weather when the temperature and the vapor pressure in a region are low, and white wet smoke plume, commonly called white smoke, can be seen. The existence of high-humidity environment can also promote pollutant generation and secondary aerosol conversion, and the treatment difficulty of the smoke is greatly increased.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide an active carbon industrial kiln smoke whitening system.

In order to achieve the above object, the present invention provides a technical solution: the utility model provides an active carbon industrial kiln flue gas white elimination system, it is including the carbide furnace, burn burning furnace, the exhanst gas outlet department of carbide furnace is connected with the flue gas and converges the house steward, flue gas converges house steward exit and is connected with the separation three-way valve, wherein one end of separation three-way valve is down with burn one of them entry linkage of burning furnace, the separation three-way valve other end upwards is connected with light cigarette conveyer pipe one end, the light cigarette conveyer pipe other end is connected with the cooler bin, be equipped with cooling coil in the cooler bin, the exhanst gas outlet department that burns burning furnace is connected with the condensation tobacco pipe, the condensation tobacco pipe is connected with the condenser, the exhanst gas outlet of condenser is connected with middle cyclone through the transition pipe, middle cyclone's exhanst gas outlet passes through middle connecting pipe and cooling coil entry linkage, cooling coil exports through returning the tobacco pipe and burn another entry linkage of burning furnace.

And a smoke exhaust three-way valve is connected at a smoke outlet of the cooling box, one end of the smoke exhaust three-way valve is downwards connected with a gas return pipe, and the other end of the smoke exhaust three-way valve is connected with an exhaust cyclone dust collector.

The return air pipe is connected with an air inlet of the carbonization furnace or an air inlet of the incinerator.

After the above technical scheme is adopted, when flue gas and tiny particle that the carbide furnace produced pass through the separation three-way valve, under the effect of separation three-way valve, tiny particulate matter falls under the dead weight and gets into burning furnace, carry out high temperature incineration through burning furnace, lighter flue gas gets into the cooler bin through the light cigarette conveyer pipe, burn burning furnace to tiny particulate matter, the flue gas that burns the production inserts the condenser through the condensation tobacco pipe and cools down (the condenser adopts water-cooling heat transfer type), flue gas after the temperature drop gets into cyclone and removes dust, the cold flue gas after the dust removal gets into the cooling coil of cooler bin, carry out the heat transfer with the high temperature flue gas in the cooler bin (the flue gas that the light cigarette conveyer pipe sent in), flue gas after the heat transfer in the cooler bin gets into the three-way valve that discharges fume, get into the cyclone dust removal of airing exhaust through the three-way valve control of discharging fume, perhaps send into carbide furnace or burn burning furnace again through returning the trachea and circulate, make the flue gas no longer discharge; the flue gas in the cooling coil gets into through returning the cigarette pipe recirculation and burns burning furnace, forms the circulation, and the flue gas after this scheme of adoption can not form the condensation liquid drop again, can not produce the white cigarette again, and through the multi-channel circulation, the flue gas preheats the raw materials in the hot-blast carbonization stove of formation through the circulation moreover.
