At present the main mode of utilizing of biomass energy is comprised: liquefaction technology, heat chemistry transformation technology (pyrolysis), the direct skill of burningArt, conversion technology. Wherein, biomass pyrolytic technology is compared with other technology, and energy conversion efficiency is high, and equipment is simple,Input cost is few, easy to operate, and process conditions are not subject to area and climatic influences. Biomass pyrolytic technology is by after biomass pyrolyticProduct mainly comprises four kinds of biomass carbon, tar, acetate solution and biological fuel gas.
Tar is a kind of mixture producing in pyrolytic process, and is the vaporific gas-flow that enters. Tar starts cohesion lower than 90 DEG C,Because tar content in biomass-pyrolysis fuel gas is high, the particle diameter of impurity is little simultaneously, the purification difficulty of biomass-pyrolysis fuel gas, tarMake it in the time of practical application, can produce irritating taste, contaminated environment, affects result of use, also can occluding device, affect itNormal operation. Therefore the research emphasis of biological fuel gas heating is to reduce tar content in biological flue gas.
In fact all physics decoking methods can not really remove tar, just tar have been transferred to condensation phase from gas phase.Current WATER-WASHING METHOD decoking technology, is to adopt clear water washing, make to bump, tackle and condense between water and tar, tar withDrop settles out, and water to be recycled, after finite concentration, send treating stations processing by sewage, and WATER-WASHING METHOD decoking can cause secondary pollutionAnd energy dissipation. And tar purifying efficiency is only 70%-80%, purification efficiency does not reach production requirement, technological process complexity,Need supporting water processing establishment.

After tar, vinegar liquid and water condensation in the utility model whirlwind condensation coke removing appts in high-temperature gas mixture along whirlwind decoking deviceInner tank wall flow to bottom with helical form and discharges, and has avoided these water and tar to follow gaseous mixture and has directly entered in conveyance conduit, makesBecome the obstruction of pipeline.
In the utility model whirlwind condensation coke removing appts, whirlwind decoking device and condenser are incorporated in a covering device, have saved number of devicesAmount, has reduced floor space.
Below in conjunction with accompanying drawing, whirlwind condensation coke removing appts of the present utility model is described further.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model whirlwind condensation coke removing appts;
Fig. 2 is A-A profile in Fig. 1;
Fig. 3 is B-B profile in Fig. 1.
Detailed description of the invention
As shown in Figure 1, the utility model whirlwind condensation coke removing appts comprises condenser and whirlwind decoking device, and condenser comprises condensationCylindrical shell 1, cooling water inlet pipe 7 and cooling water outlet pipe 6, cooling water inlet pipe 7 is arranged on condensation cylindrical shell 1 lower end, cooling waterOutlet pipe 6 is arranged on condensation cylindrical shell 1 upper end, and whirlwind decoking device 3 is arranged on condensation inner barrel, on whirlwind decoking device 3, arrangesHave air inlet pipe 4 and escape pipe 5, air inlet pipe 4 tangentially arranges along whirlwind decoking device, through condensation cylindrical shell 1 and whirlwind decoking device 3Upper end is connected, and escape pipe 5 is inserted into whirlwind decoking device 3 inside through condenser overhead, and whirlwind decoking device 3 lower ends are tapered,Stretch out from condenser bottom, whirlwind decoking device bottom is provided with sewage draining valve 9.
In condenser condenses cylindrical shell, be provided with one group of deflector 2, a side breach of deflector 2, shape between breach and condensation cylindrical shellBecome space, deflector is fixed on condensation inner barrel up and down successively, space alternately appears at cylindrical shell both sides, guiding current roundabout toUpper flowing, increases the cooling effect to whirlwind decoking device cylindrical shell by the effect of deflector.
Be provided with flange 8 in the bottom of this taper, for making sewage draining valve for convenience detach 9, facilitate the maintenance of sewage draining valve and moreChange, prevent from can not normally using because the obstruction of tar in valve causes whole equipment. Sewage draining valve 9 will ensure that air-tightness is good simultaneously,To prevent that whirlwind decoking device bottom from leaking out, affect decoking effect.
Whirlwind decoking barrel diameter is controlled at below 800mm, in order to avoid affect decoking effect.
Mixed flue gas after pyrolysis enters in whirlwind decoking cylindrical shell 1 by air inlet pipe 4, and cooling water enters from cooling water inlet pipe 7,Flow out from cooling water outlet pipe 6, mixed flue gas condenses into little water droplet by the effect of cooling water by water, acetate solution and tar, increasesAdd the granularity of coke tar particles, and whirlwind decoking device is used for good removal effect, coarse granule for the coarse granule of granularity >=10 μ mFlow in cone through separating, fall into separator bottom, discharge through sewage draining valve 9, the combustion gas after purification is discharged by escape pipe 5.
Mixed flue gas intake velocity is controlled at 10m/s-20m/s, avoids the too low impact effect of speed, the mill of the too high increase cylindrical shell of speedDamage. , because tar viscosity is large, be easily attached on an inwall meanwhile, can play certain protective effect to barrel.
The flue gas producing in biomass pyrolysis process contains a large amount of vinegar liquid, tar and water, and not opening for a long time sewage draining valve can makeThis installs obstruction; The single sewage draining valve of opening, can reduce the decoking effect of this device. So generally by parallel two these devices,Smoke inlet pipe is equipped with stop valve, when a job, and another rest. When the device of work need to be opened bottom blow-down valveWhen blowdown, open the air inlet pipe of another table apparatus, close the air inlet pipe of this equipment and carry out blowdown, realize continuously and producing.
For increasing the decoking effect of this device, each operation workshop section can adopt 2 above whirlwind condensation coke removing appts series connection.
Cooling water enters in tank body from outside, and high-temperature gas mixture temperature is reduced rapidly, because the pipeline in tank body is by cooling waterWith gaseous mixture isolation, cooling water does not directly contact with gaseous mixture, and cooling water can recycle, in reduction mixture temperatureMeanwhile, avoid the generation of waste water, greatly alleviated the pressure of wastewater treatment, reduced cost; Tar in high-temperature gas mixture,After vinegar liquid and water condensation, flow to bottom along whirlwind decoking device inner tank wall with helical form and discharge, avoided these water and tar to followGaseous mixture directly enters in conveyance conduit, causes the obstruction of pipeline; Whirlwind decoking device and condenser are incorporated in a covering device, jointEconomize number of devices, reduced floor space.
Above-described embodiment is described preferred embodiment of the present utility model, not to of the present utility modelScope limits, and is not departing under the prerequisite of the utility model design spirit, and those of ordinary skill in the art are to the utility modelTechnical scheme various distortion and the improvement made, all should fall in the definite protection domain of the utility model claims.
