Description
Technical field
The invention belongs to gas purification technique field, more particularly, to a kind of cryogenic condensation tar collector.
Background technology
Coal combustion produces a large amount of pollution noxious materials, and ecological environment can be caused to have a strong impact on.Coal Gasification Technology can be by
Coal changes into high-grade gaseous fuel by thermochemical process, is a kind of clean coal technology.Biomass are rich as a kind of resource
Proportion of the clean reproducible energy carrier of rich, wide material sources in energy consumption structure increasingly increases, and gasification of biomass is same
The gaseous fuel of high-quality can be obtained, is considered as a kind of very promising thermochemical study technology.Coal gasification and biomass
The gas products of gasification can serve as generating electricity, also can be used as important industrial chemicals.However, either coal gasification or biomass
Gasification all inevitably produces part tar, and these tar can reduce coal or biology in being entrained in gaseous products in high temperature
Charcoal percent conversion in matter, so as to reduce the yield and quality of gas.In order to improve coal gasification or gasification of biomass efficiency of carbon con version and
GAS QUALITY, it is necessary to which property and formation mechanism to tar are furtherd investigate, and it is critical only that and tar is separated simultaneously from gas
Collect.
At present, used tar collection mode mainly includes condensation method, molten in coal gasification or gasification of biomass research
Agent absorption process and solid phase adsorption method.These methods respectively have deficiency：1) condensation method is that more method is used in studying, usually used
Water, mixture of ice and water or liquid nitrogen are used as cooling medium.The temperature of water is generally room temperature, and the temperature of mixture of ice and water is normally close to zero
Degree, both cooling mediums are poor less than the tar ingredients condensation effect of zero degree for dew point；The temperature of liquid nitrogen is extremely low, Ji Huke
Condensed with by all tar, but (- 196 DEG C) boiling points less than most gaseous products of the temperature of liquid nitrogen, by tar
Also most of gaseous product is condensed out while condensation, is caused the loss of gas and is unfavorable for being collected gas and divides
Analysis；2) solution absorption method is also conventional tar collection method, and because the composition of tar is generally organic matter, this method is generally adopted
With organic solvents such as acetone, dichloromethane, methyl alcohol, toluene as tar lyosoption, while using mixture of ice and water, brine ice
Strengthen the assimilation effect of tar Deng cooling medium, but tar ingredients are extremely complex, and different compositions is molten in organic solvent
Solution property is different so that organic solvent shows selective absorbing to heterogeneity in tar, so as to be difficult to ensure that tar is effectively inhaled
Receive；On the other hand, the organic solvent for being used has volatility, loss occurs in absorption process and causes tar collecting effect
Difference；And solution absorption method is usually using more absorption bottle, the later stage separates and collects from organic solvent tar relatively complicated；3)
Condensation method or solution absorption method are typically to be placed in absorber in the container equipped with cooling medium, the general effect of heat insulation of these containers
Difference, cooling medium temperature is raised during absorbing tar, can cause the reduction of tar absorption efficiency；On the other hand, cooling medium exists
Remained static in container, it is poor with containing heat transfer effect between tar gas；4) the tar adsorption effect of solid phase adsorption method is closed
Key is the absorption property of adsorbent, and conventional solid-phase adsorbent is the larger adsorbents of specific surface area such as activated coke, molecular sieve,
Although its tar adsorption effect preferably, needs to reclaim tar using thermal desorption, operating process is complicated and the tar rate of recovery is difficult to
Ensure.
