Description
Technical field
The present invention relates to a kind of from removing tar formula biomass fixed-bed gasification furnace system.
Background technology
Biomass are ten minutes important renewable energy, have characteristics such as recyclability, low contaminative and extensive distributivity.Utilize the biomass energy as an alternative, to low carbon emission reduction, reduce " Greenhouse effect " and improve the atmosphere acid rain environment and have very important meaning.Biomass gasification system utilizes biomass airtight anoxia burning in vapourizing furnace exactly, by producing inflammable gas after destructive distillation pyrolysis and the thermochemistry oxidation.
Fixed-bed gasification furnace is the important kind of biomass gasification system.In the fixed-bed gasification furnace, fuel exists with the state of piling up in stove, finishes gasification in the mode of grate firing.Fixed-bed gasification furnace because the fuel thermal decomposition time longer, binder is more, so the coal-tar middle oil content of combustion gas is higher, add the institute fuel gas temperature that produces lower, cause tar very easily to be separated out, thus the obstruction gas pipeline.
At present the gasifying biomass furnace system adopt more outside except tar as washing etc., perhaps by increase by two, tertiary air improves the biological fuel gas temperature and solves or alleviate the tar problem.
For example, Chinese patent application 201010251310.2 discloses a kind of large-scale fixed bed biomass gasifying electricity generation production technique and suite of equipment, and it is made up of four parts: (1) raw material pretreatment portion mainly comprises raw material collection, oven dry and formation system; (2) gasifying biomass part is mainly macro-organism matter fixed-bed gasification furnace and relevant auxiliary facility thereof; (3) gas sweetening part mainly comprises ash disposal, removes equipment such as tar, desulfurization, dechlorination; (4) fuel gas generation part, the combustion gas behind the deep purifying mainly utilizes combustion power generation in the oil engine.
Chinese patent application 201110385439.7 discloses the fixed bed biomass gasification Processes and apparatus that a kind of tar classification is collected, the high temperature filtration fly-ash separator that setting links to each other with vapourizing furnace, a plurality of tar wells of contacting in the air outlet of high temperature filtration fly-ash separator, distinguished and admirable to top or the bottom feeding gasification of vapourizing furnace through gasification wind inlet tube, the high-temperature gas mixture body that contains tar in the vapourizing furnace is discharged, under the condition that keeps temperature, enter the high temperature filtration fly-ash separator through first airway and carry out high-temperature dust removal, enter a plurality of tar well staging treating of polyphone afterwards through second airway, obtain the tar of different components.The section of heating up in a steamer according to the coal-tar middle oil composition of combustion gas is different, utilizes the tar in the type of cooling classification collection combustion gas, effectively utilizes according to the difference of the composition of collecting again.
In the technique scheme, adopt the outside tar that removes, the tar of separating out by the outside washing enters in the environment with water, causes the pollution of recirculated water and the deterioration of Working environment, and outside atmosphere is caused serious pollution.
And improve fuel gas temperature by increase by two, tertiary air, the calorific value that is actually to sacrifice combustion gas is cost, and improve fuel gas temperature to the also raising greatly of requirement of gas pipeline and follow-up equipment, cost also will increase thereupon, and follow pipeline to prolong, the combustion gas cooling inevitably appears, in case cooling will produce tar.
These two kinds of technology all are the tar problems that solves under the prerequisite of sacrificialing environment, cost of investment (work-ing life of equipment) or output efficiency, and very obvious defects is arranged.
Therefore, how to provide a kind of can the realization to remove the tar effect preferably, can become the problem that industry need solve at the biomass gasification system that does not reduce output efficiency and service life of equipment and environment is not polluted again.
