The utility model discloses the technology that a secondary upper end tube wall of a cyclone separator (6) is welded and communicated with one end of a heat-return pipe B (7), while the other end of the heat-return pipe B (7) is welded and communicated with a tube wall of a fuel pre-heater (2); an exhaust pipe of an engine (4) is communicated with one end of a heat-return pipe A (5), while the other end of the heat-return pipe A (5) is welded and communicated with an upper end tube wall of a stock bin pre-heater (1). The biomass gasification power generation device is characterized by simple and compact structure, convenient device manufacturing and significant effect of using the waste heat, etc.
Description
One, technical field
The utility model relates to the living beings gasification and generation device, especially a kind of biogas elelctrochemical power generation utilize the waste heat preheating fuel device.
Two, background technology
Regenerative resource is the important energy source of human sustainable development from now on, biogas elelctrochemical power generation and comprehensive utilization, not only developed regenerative resource, also can be with its multiple byproduct comprehensive utilization, reduce the discarded of living beings and pollute, increase farming, forestry products added value, biogas elelctrochemical power generation comprehensive utilization meets the theory of building a resource-conserving and environment-friendly society and developing a circular economy.
By biomass gasifying furnace or the next pyrolysis biological fuel gas of retort, the dust and the gas phase tar that contain suitable concentration, no matter as the source of the gas of centralizedly supply life combustion gas, or as the gaseous fuel of internal combustion engine generating, all require it is purified cooling processing, promptly strict dedusting, remove tar and cooling.At the Chinese patent publication number is CN2680671, " a kind of economic and practical purification and cooling device " patented technology was disclosed on February 23rd, 2005, adopted gas outlet to be in series with two to three grades of separation cyclone scrubbers at gasification furnace, separate the outlet of deduster lower end and be connected with one to secondary moisture film spray washing cooling tower, the gas outlet of moisture film spray washing cooling tower is in series with the two-stage Venturi scrubber, this scrubber port of export links with two to three grades of moisture film spray washing cooling towers again, link through Roots's air-introduced machine and auto-excitation type decoking device then, the auto-excitation type decoking device is communicated with gas storage holder by dedusting and the moisture trap that removes tar, and it can remove dust and tar in the combustion gas.Exist the water spraying cooling, make water contain tar and the not easily separated removal of other material, contaminated environment, equipment is huge, weak points such as investment cost height.Underusing the high-temperature tail gas that the exhaust pipe of engine is discharged simultaneously, is a kind of energy waste.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, and the high-temperature gas that makes full use of high-temperature tail gas that engine discharges and cyclone separator returns feed bin and comes preheating fuel device.
Technical scheme that order of the present utility model adopts is, include feed bin preheater, fuel preheater, gasification furnace, engine, cyclone separator, logical heat return pipe B one end of upper end, second level barrel welding of its cyclone separator, the logical fuel preheater tube wall of heat return pipe B other end welding, waste pipe is connected heat return pipe A one end, the logical feed bin preheater of heat return pipe A other end welding upper end barrel.
The utility model is to make full use of the high-temperature tail gas that the exhaust pipe of engine is discharged, utilize high-temperature gas that the fuel in the feed bin preheater is carried out The pre-heat treatment, fuel through The pre-heat treatment is carried at helical feed machinery, enter fuel preheater and be subjected to again heating from the high-temperature gas that cyclone separator comes, this moment, fuel was subjected to high temperature preheating twice, entered gasification furnace, the easier pyrolysis of fuel becomes biological fuel gas, shorten pyrolysis time, make full use of waste heat, utilize the energy, help environmental protection.It is simple and compact for structure, makes easy to assemblyly, utilizes waste heat, characteristics such as its effect is obvious.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
Among the figure: 1-feed bin preheater 2-fuel preheater 3-gasification furnace 4-engine 5-heat return pipe A 6-cyclone separator 7-heat return pipe B
Five, the specific embodiment
As shown in drawings, include feed bin preheater 1, fuel preheater 2, gasification furnace 3, engine 4, cyclone separator 6, logical heat return pipe B7 one end of upper end, second level barrel welding of its cyclone separator 6, logical fuel preheater 2 tube walls of heat return pipe B7 other end welding, the blast pipe of engine 4 is connected heat return pipe A5 one end, the logical feed bin preheater 1 upper end barrel of heat return pipe A5 other end welding.
