Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Using biomass if agricultural crop straw, rice husk, wormwood, fuel wood, forestry processing waste etc. are as biomass material, utilize the compact formed technology of biomass material cold conditions, by compressed moulding, it is 25～35mm that biomass material is made to diameter, length is the particle of 50～100mm, not only solve the difficult problems such as biomass material transportation, storage, also improved greatly the gasification intensity of biomass material in vapourizing furnace.
Adopt the compact formed technology of biomass cold conditions that the technical process of biomass material granulation is as follows: biomass material is broken, packing, dry, pulverizing, moulding, then carry out cooling and store.
Biomass material is prepared to after particle, and this raw material is added in stove from the furnace roof portion of two-part fixed bed updraft type vapourizing furnace.As shown in Figure 1, the furnace chamber of vapourizing furnace is divided into 103 3 sections of drying layer 101, pyrolytic layer 102 and zone of combustion, and when biomass material adds this vapourizing furnace, the drying layer temperature that need to control this vapourizing furnace is 120～275 ℃, pyrolytic layer temperature is 275～600 ℃, and zone of combustion temperature is 800～1000 ℃.The boundary of in fact above-mentioned drying layer 101, pyrolytic layer 102 and zone of combustion 103 is difficult to clearly divide, there is certain intersection in each stage, also there is certain intersection in the temperature range in each stage, when controlling the internal temperature of vapourizing furnace, if control each layer main body temperature range of vapourizing furnace and temperature from top to bottom increase progressively trend.From this vapourizing furnace bottom, pass into vaporized chemical, this vaporized chemical is the mixed gas of oxygen and water vapour, biomass material is carried out to pyrolytic gasification, in stove, keep normal pressure, at the zone of combustion upper epidermis place of vapourizing furnace, guarantee that oxygen is by perfect combustion, approach exhaustion, therefore through pyrolytic layer gas, be oxygenless gas, for the static decoking purification process in later stage provides safety control.
Oxygen in vaporized chemical is that VPSA oxygen generation system is mainly comprised of gas blower, vacuum pump, switching valve, adsorber and oxygen surge tank by the separated preparation of pressure swing adsorption oxygen VPSA.Air is removed after dust granule through suction port strainer, is pressurized to 30～50kPa and enters wherein in an adsorber by Root's blower.Filled with adsorbent in adsorber, wherein moisture, carbonic acid gas and on a small quantity other gaseous fractions in adsorber ingress, be loaded in the activated alumina of bottom and adsorb, nitrogen is loaded in the zeolite molecular sieve on activated alumina top and adsorbs subsequently.And oxygen (comprising argon gas) drains in oxygen surge tank temporarily storage from adsorber top exit as gas product for non-absorbed component, and be supplied to vapourizing furnace.
Biological particles raw material, after vapourizing furnace pyrolytic gasification, obtains biomass rough gas, now in biomass rough gas, contains the impurity such as dust, tar and water vapour of higher composition, need purify by purification process.

Except defocused biological fuel gas enters washing tower and air water separator washing and dehydration.Remove the trickle ionized impurity in biomass rough gas, gained biomass rough gas ash oontent≤1mg/Nm
3.With the combustion gas after air water separator dehydration, become finished product combustion gas, finished product combustion gas is imported in low pressure gasholder and stored.
Owing to containing inorganic sulfur and a large amount of organosulfurs in biological fuel gas, and chemical industry has strict requirement to the sulphur content of raw material, therefore finished product combustion gas can't directly be applied to the synthetic industry of the chemical industry such as ammonia and urea as industrial chemicals, must adopt appropriate means to carry out desulfurization processing to finished product combustion gas.
The present invention adopts dry desulfurization and smart desulfurization combination desulfurization method to carry out desulfurization to finished product combustion gas, dry desulfurization is the thick desulfurization of normal temperature, take ferric oxide as sweetening agent, deviate from the hydrogen sulfide in gas, generate iron sulphide, and iron sulphide contacts with the oxygen in combustion gas, under the condition that has moisture to exist, be oxidized to ferric oxide and separate out elemental sulfur, thereby sweetening agent is regenerated.Dry desulfurizing process is simple, desulfurization precision is high.Essence desulfurization is high temperature desulfurizing with pressure, and the organosulfur in finished product combustion gas is decomposed and obtains H
2after S by H
2be removed to≤0.1mg/Nm of S
3.According to the sulfur-bearing situation that enters the finished product combustion gas of gas-holder after evolving, adopt the refining scheme of cobalt molybdenum-zinc oxide desulfurization.For reducing process cost, guarantee the safety in production of device long period, a cobalt molybdenum desulphurization reactor is set, two ZnO desulphurization reactors, can connect, also can parallel operations, make ZnO utilization ratio can reach 100%, and can, in the situation that not stopping work, change sweetening agent.The H of the finished product combustion gas of process dry desulfurization and smart desulfurization
