Energy-saving clean Activated Carbon Production system
Technical field
The utility model relates to a kind of device that uses gaseous activator to prepare gac, particularly relates to a kind of Activated Carbon Production system that Stepple furnace and revolving activation furnace are used in combination.
Background technology
The flue gas that is used to produce the Stepple furnace of gac at present normally directly enters air after purifying, though also some is got back in the stove by jet, but also have after all 60~80%, water content be the flue gas of oxious components such as physics method activated media, sulfurous gas and carbonoxide such as 50~65% carbonic acid gas, nitrogen without purification utilization, enter in the atmosphere with 250 to 500 ℃ flue-gas temperatures.So not only wasted effective constituent and the heat in the flue gas, and caused the pollution of air,, also needed to be equipped with corresponding treating plant for flue gas is purified.One ton of gac of wherein every production needs 6 tons of consume water, 2 tons of standard coals of consume fuel.
Rotary activated furnace also is a kind of device of producing gac, and the burner of this device is provided with opening for feed, vapour pipe and aid distributing pipe, material is thrown in to body of heater fluming water steam and air in stove from vapour pipe and aid distributing pipe, the H in the water vapor from opening for feed
2C in O and the material carries out priming reaction at a certain temperature, and material obtains gac through behind the priming reaction.In whole priming reaction, need the temperature (about 900 ℃) that keeps higher in the stove, and need make up water steam in stove constantly, one ton of gac of every production needs 5 tons of consume water, 1.6 tons of standard coals of consume fuel.
The utility model content
The technical problems to be solved in the utility model provides a kind of activation tail gas that can effectively utilize Stepple furnace, alleviates the flue gas environmental pollution, reduces the energy-saving clean Activated Carbon Production system of Activated Carbon Production cost.
The utility model energy-saving clean Activated Carbon Production system, comprise Stepple furnace and revolving activation furnace, the regenerator bottom of described Stepple furnace is provided with the activation exhaust port, the burner of described revolving activation furnace is provided with vapour pipe, and the activation exhaust port of described Stepple furnace is connected with the vapour pipe of revolving activation furnace by flue.
The utility model energy-saving clean Activated Carbon Production system, wherein said flue is provided with induced draft fan.
The utility model energy-saving clean Activated Carbon Production system, the exhaust port of wherein said revolving activation furnace stove tail is connected with the inlet mouth of waste heat boiler.
The utility model energy-saving clean Activated Carbon Production system, the venting port of wherein said waste heat boiler is connected with the inlet mouth of desulfation dust-extraction device.
The utility model energy-saving clean Activated Carbon Production system, the venting port of wherein said desulfation dust-extraction device is connected with chimney.
The utility model energy-saving clean Activated Carbon Production system, wherein said desulfation dust-extraction device is an integrated gas purifying tower.
The utility model energy-saving clean Activated Carbon Production system difference from prior art is that the utility model energy-saving clean Activated Carbon Production system directly is delivered to the activation tail gas of Stepple furnace in the body of heater of revolving activation furnace, makes the CO in the Stepple furnace activation tail gas
2Enter in the revolving activation furnace with water vapour, participate in the middle of the priming reaction as activator, the waste heat of Stepple furnace activation tail gas can heat the body of heater of revolving activation furnace, provides priming reaction required temperature.Make active substance and heat in the activation tail gas of Stepple furnace be utilized effectively by the utility model energy-saving clean Activated Carbon Production system, and alleviated the pollution of flue gas to environment, simultaneously, make that again the running cost of revolving activation furnace is effectively reduced, produce one ton of gac by native system, only consume water is 2 tons, and consume fuel is taken 0.8 ton of standard coal, effectively reduced the consumption of water resources and the consumption of the energy, made cost obtain bigger decline.
Below in conjunction with accompanying drawing energy-saving clean Activated Carbon Production of the present utility model system is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model energy-saving clean Activated Carbon Production system.
Embodiment
As shown in Figure 1, the utility model energy-saving clean Activated Carbon Production system comprises Stepple furnace 1 and revolving activation furnace 2, the regenerator bottom of Stepple furnace 1 is provided with activation exhaust port 11, the burner of revolving activation furnace 2 is provided with vapour pipe 21, and the activation exhaust port 11 of Stepple furnace 1 is connected with the vapour pipe 21 of revolving activation furnace 2 by flue 3.Flue 3 is provided with induced draft fan 4, and the exhaust port of revolving activation furnace 2 stove tails is connected by the inlet mouth of pipeline with waste heat boiler 5.The venting port of waste heat boiler 5 is connected by the inlet mouth of pipeline with desulfation dust-extraction device 6, desulfation dust-extraction device 6 adopts the disclosed a kind of integrated gas purifying tower of Chinese patent CN200820110253.4, and the venting port of desulfation dust-extraction device 6 is connected with chimney 7 by pipeline.
The working process of the utility model energy-saving clean Activated Carbon Production system is summarized as follows: the material after the charing is added respectively in Stepple furnace 1 and the revolving activation furnace 2, to carry out priming reaction in water vapour and the air feeding Stepple furnace 1, the activation tail gas that produces behind the priming reaction is discharged from the activation exhaust port 11 of regenerator bottom, under the effect of induced draft fan 4, be rich in waste heat, CO
2Enter in the body of heater with the activation tail gas of water vapour vapour pipe 21 from revolving activation furnace 2 burners, carry out priming reaction with the material in the revolving activation furnace 2, discharge from revolving activation furnace 2 stove tails through the tail gas that priming reaction produces, enter waste heat boiler 5 recovery waste heats, purify the back through desulfation dust-extraction device 6 then and discharge from chimney 7.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
