Abstract
The utility model discloses a device for purifying tar of fuel gas of a household biomass gasification furnace. The device comprises a gasification furnace body, a purification chamber, a recovery pipe, a cracking pipe inside the gasification furnace and the like. After being exhausted from the top of the gasification furnace, gasified fuel gas flows into the purification chamber arranged outside the furnace; a plurality of left baffle plates, right baffle plates and longitudinal partition plates are arranged in the purification chamber; appropriate size of partition plates can enable the flowing areas of fuel gas to keep basically the same; after fuel gas is deflected several times in the purification chamber, the tar and the water which are condensed gradually due to the lowering of temperature flow into the recovery pipe provided with a U-shaped liquid seal section, along the purification chamber wall; and after the collection of the recovery pipe, the tar flows into a semicircular cracking pipe positioned in the high-temperature oxidation zone of the gasification furnace and tightly clinging to the inner container of the gasification furnace in a circulating manner. The device with simple structure, little resistance to the flowing of system and easy implementation realizes the purification of tar of fuel gas of the household biomass gasification furnace, cannot cause secondary pollution, and can improve the gas generation efficiency and gas heating value of the gasification furnace.
Description
Affiliated technical field
The utility model relates to vapourizing furnace, is specifically related to the apparatus structure of a kind of family with the coal-tar middle oil purification of biomass gasification furnace gas, belongs to the biomass gasification technology field of renewable energy utilization.
Background technology
Tar is the inevitable byproduct of gasifying biomass, and updraft type is often adopted with biomass gasifying furnace in existing family, and the tar that causes cracking zone to generate is not directly sneaked into and discharged in the gasification burning through the gasification zone, so the coal-tar middle oil content height of aerogenesis.Tar with combustion gas from the flow process that vapourizing furnace is discharged as without effective processing, temperature is reduced to condensing temperature gradually and is deposited on pipeline, valve, gas kitchen ranges etc. and locates, not only the long-term stability operation to gas burning system causes very big harm, and has reduced the efficient of biomass gasification system.
Summary of the invention
The utility model is used absorbing biomass gasification furnace at existing family can't adopt complicated refining plant, the problem that has tar content height, easy blocking pipe, kitchen range, the tar purifying device that provides a kind of vapourizing furnace to discharge combustion gas is to improve gasification efficiency, to satisfy the demand of vapourizing furnace steady running.
The technical scheme that the utility model adopted is:
1. vapourizing furnace body of heater (6) is cylindrical, the below of fire grate (3) is cinder chamber (17), cinder chamber is provided with ash discharging hole (2), the top is useful on the bell (7) of sealing, biomass material adds from furnace roof portion material inlet (8), vaporized chemical (air) blasts from the air intlet pipe (16) of body of heater bottom, enters burner hearth (5) through fire grate (3), and the combustion gas of output is discharged from top of gasification furnace.
2. the vapourizing furnace aerogenesis compiles inflow decontamination chamber (10), back from furnace roof portion, multi-disc left side traverse baffle (9), right traverse baffle (13) and wash plate (12) are arranged in the decontamination chamber, and left traverse baffle, right traverse baffle should make gas-flow out of date circulation area keep identical substantially with the size Selection of wash plate.
3. the gas-flow that contains tar is in the process of left traverse baffle (9), right traverse baffle (13), wash plate (12), flow direction constantly changes, the tar and the condensed water of condensation are thrown to the purification locular wall under mass force and centrifugal action with the temperature reduction in the combustion gas, flow into the recovery tube (14) that links to each other with the bottom, decontamination chamber along wall, collect by recovery tube.
4. a U type fluid-tight section is established at recovery tube (14) middle part, and its outlet links to each other with the import of cracking tube (4) in the stove.The tar of collecting drips with condensed water and flows into the semicircle camber cracking tube that is positioned at vapourizing furnace high temperature oxidation district downwards through recovery tube.
5. combustion gas that vapourizing furnace produces realizes the separation of tar drop from combustion gas at the repeatedly baffling of inside, decontamination chamber, and flows into the cracking tube that the furnace high-temperature section is provided with through the recovery tube circulation, is cracked into inflammable gas under the effect of furnace high-temperature and catalyzer; (11) flow to kitchen range through the air outlet in combustion gas after the purification.
The utility model realized the family with biomass gasifying furnace to the coal-tar middle oil requirement that purifies of combustion gas, and can not cause secondary pollution, and can improve the gas producing efficiency and the fuel gases calorific value of vapourizing furnace, have that apparatus structure is simple, system flow resistance characteristics little, easy to implement.
