Description
Technical field
The utility model belongs to boiler flue gas purification technology, specifically gasifying biomass kiln gas self-purifying device.
Background technology
Pyrolysis gas of biomass utilizes biomass material to pass through airtight anoxia, adopt dry pyrolysis method and the rear a kind of inflammable gas produced of thermochemistry oxidation of slipping, containing carbon monoxide, hydrogen, methane, hydrocarbon etc., except containing except above-mentioned inflammable gas, also containing nitrogen, carbonic acid gas and particulate matter, along with smoke emissioning pollution environment after burning, therefore biogas can be used safely after need purifying and becoming clean fuel gas.Traditional pyrolysis gas purification generally adopts the methods such as cyclonic separation, Electrostatic, condensation dehydration, spray washing, not only complex structure, floor space is large, working cost is high, easily cause secondary pollution, suddenly reduce because of pyrolysis gas temperature in scavenging process simultaneously and make the tar in combustion gas condense into liquid precipitation thus reduce the thermal value of pyrolysis gas, also can coking, blocking, corrosion pipeline and gas utensil eyelet.The particulate matter produced after biomass pyrolytic gas firing produces primarily of following approach:
1. the updraft type fixed-bed gasification furnace generally used at present has that investment is little, Energy harvesting is abundant, gasification efficiency is high, fuel gases calorific value is higher, the grey advantage such as few of gas belt, but because vapourizing furnace feed points is just in time gas outlet position, and opening for feed is higher than air outlet, enter burner burning because the mutual frictional impact of raw material produces chip with combustion gas discharge during charging, form biomass ash after burning and discharge with flue gas;
2. because charging is unbalanced, effectively can not filter combustion gas when stove internal combustion bed of material position is too low, the biomass ash produced during the burning of vapourizing furnace zone of oxidation is discharged with combustion gas;
3. due in traditional scavenging process pyrolysis gas temperature suddenly reduce make the coal-tar middle oil condensation of combustion gas after with combustion gas enter burner burning, formed carbon black fine particle discharge with flue gas.
Utility model content
The purpose of this utility model is to provide gasifying biomass kiln gas self-purifying device.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
Gasifying biomass kiln gas self-purifying device, be made up of biomass gasifying furnace, the first cyclonic separator, the second cyclonic separator, settling pocket, burner, dust stratification case and thermal insulation layer, described biomass gasifying furnace, the first cyclonic separator, the second cyclonic separator, settling pocket, dust stratification case are arranged in thermal insulation layer.

Described burner is made up of vane swirler, and described vane swirler one end is high-temperature fuel gas outlet, the other end is connected with gas pipeline; Described gas pipeline is provided with high temperature combustion air inlet and high-temperature biomass gas import.
The biogas outlet of described biomass gasifying furnace is connected with the biogas import of the first cyclonic separator; The biogas outlet of described first cyclonic separator is connected with the biogas import of the second cyclonic separator; The biogas outlet of described second cyclonic separator is connected with the biogas import of settling pocket; The biogas outlet of settling pocket is connected with the high-temperature fuel gas import of burner by gas pipeline; The high temperature comburent air duct of thermal insulation layer is connected with the high temperature combustion air inlet of burner.
The utility model advantage:
1. utilize the high warm air of high-temperature zone as pyrolysis catalysts, improve the scission reaction temperature of biomass, biomass fuel in oxidation zone with 1100 DEG C ~ 1300 DEG C, burn in the oxygen debt atmosphere of high temperature of gasification equivalence ratio 0.26, the oxynitride of generation is few; Biogas dust content after the fuel bed in vapourizing furnace filters is very low, the chip that gas dust-laden produces mainly due to the mutual frictional impact of raw material during charging causes, the chip that native system charging the produces water vapor that in absorption dehydration district, fuel drying process produces in negative area and rapidly sedimentation, thus minimizing gas dust content, then the flue gas of biological fuel gas post combustion emission after system purification meets the newly-built gas fired-boiler emission limit in GB13217-2014 " emission standard of air pollutants for boilers ": particulate matter 20mg/m
3, oxynitride 200mg/m
3, sulfurous gas 50mg/m
3, lingemann blackness 1 grade.
2. because biogas fully mixes with high temperature combustion air by eddy flow burner, tar in high-temperature fuel gas can not be separated out and Thorough combustion, during burning, flame temperature reaches 1100 DEG C ~ 1300 DEG C, in coke tar cracking process, intense reaction produces the oxynitride in free group reduction flue gas, reduces the quantity discharged of oxynitride further; While having maximally utilised biogas thermal value, also can not cause the coking of boiler heat exchange face, ensure boiler output.
