Description
Technical field
The present invention relates to combustion equipment, especially relate to a kind of biomass non-pressure gas making machine that uses inferior solid-state biomass to carry out extensive aerogenesis as raw material.
Background technology
Biomass gasification technology is meant under unburnt condition, utilizes airborne oxygen or oxygen carrier to make vaporized chemical, with Wood Adhesives from Biomass for containing H
2, CO, CH
4Process Deng inflammable gas.At present biomass thermal chemical conversion technology is a kind of of tool practicality in the gasification technology; It is that inferior solid-state biomass is converted into high-quality inflammable gas; It can be widely used in and drive oil engine, Stirling hot-air engine generating and agricultural irrigation equipment, or directly is used for cooking, heating, used for drying corps and Industrial products oven dry etc.And inferior solid-state biomass is exactly the waste (like husk, wood chip, stalk) of grain and farm-forestry crop, all kinds of combustible life, medical rubbish and all types of industries product deutero-incendivity waste etc.; They are a kind of inexhaustible substitute energys; Be a kind of renewable resource of preciousness, and China is to the technological lag that utilizes of biomass energy, utilization ratio less than 10%; All the other mostly go out of use or commit to the flames, very unfortunately.
Biomass gasification technology mostly is through the air combustion direct gasification, and the combustion gas that is produced all is low heating value gass, and the general heating amount is 5MJ/m
3About.The biomass indirect gasification technology that adopts outside heat supply is also arranged, owing to do not contain N in its combustion gas composition
2, thereby calorific value can reach 10-15MJ/m
3Particularly when water vapor is made gasifying medium, can obtain H
2Content reaches the combustion gas about 50%.At present, all biomass gasification device all exists the temperature of thermal chemical reaction in the gasification installation and effective product combustion gas (H
2, CO, CH
4) matching problem of turnover ratio, and this just directly caused in the gas generation process part effectively the product combustion gas be converted into carbonic acid gas, waste water and tar, make the productive rate of effective product combustion gas descend and form second environmental pollution.
Owing to contain impurity such as a large amount of tar, ash content and water vapor in the combustion gas of gasifying biomass, must it be removed and just can obtain effective product combustion gas.Tar is a kind of complex compound of being made up of aromatic hydrocarbon and verivate thereof and polycyclic aromatic hydrocarbons, and the component that can analyze just reaches kind more than 100, also has a lot of compositions to be difficult to confirm.Wherein massfraction is respectively benzene, naphthalene, toluene, YLENE, vinylbenzene, phenol and indenes greater than 5% nearly 7 kinds.Biomass coke tar is gaseous state being liquid below 200 ℃ more than 300 ℃, at high temperature can resolve into the small molecules permanent gases.In biomass gasification process, the subject matter that tar produces the back existence has: (1) tar accounts for the 5%--10% of combustible gas energy, is difficult at low temperatures utilized by burning with combustion gas, and waste is serious; (2) tar condenses into liquid at low temperatures, and Yi Heshui, carbon granule etc. combines, and stops up gas pipe line, blocks valve, corroding metal, and causing can't trouble-free burning; (3) tar is difficult to perfect combustion, and produces particle such as carbon black, and is serious to the gas-fired equipment infringement; (4) smell of tar and the generation of burning back thereof has the trace infringement to human body.This shows that the tar in the combustible gas has sizable hazardness, is the biggest obstacle that gasification is used.Therefore, how tar is changed into effective product combustion gas (H
2, CO, CH
4) become a urgent problem.
At present, the Technology of removing tar and dust both at home and abroad mainly contains three kinds of wet purification, dry purification and cracking purifications.
System for wet purification mainly is to adopt the method for water washing to remove tar and dust; This purification system generally is to link together two or more washing purifiers; System cost is lower, and is simple to operate, this mode of the general employing of the purification system at biomass gasification technology initial stage; But this mode is eliminated owing to there is following shortcoming gradually: 1, contain the waste water directly discharging usually of tar, cause secondary pollution; 2, a large amount of tar lose with current, cause the waste of energy; 3 change effects are bad.
Dry cleaning system is the purifying method of the cascade filtration that adopts for the pollution problem of avoiding tar; Like the two stage cyclone fly-ash separator dedusting of in fixed bed lower suction type biomass gasifying furnace, adopting; One-level tubular cooler and box filter purification system without grit and tar in the thick gas of water washing, can be avoided the secondary pollution to water and soil earth like this; But it is bad that this purification system is removed the effect of tar, and the deposition of tar is very serious.
To the tar in the gasification; The good method that can take is to be converted into combustible gas to it; Both can improve the vapourizing furnace gasification efficiency, can reduce the coal-tar middle oil content of combustion gas again, improve the utility value of combustible gas; The cracking purification techniques is to make it be cracked into available disposable gas someway the tar utilization that is produced in the gasification, and its method has thermo-cracking, catalytic pyrolysis, electric cracking etc.Ways such as simple in the past washing or filtration are just separated tar from gas; Not only waste the energy of tar itself but also produced a large amount of pollutions; Thermo-cracking needs very high temperature and enough residence time, has implemented certain difficulty, and catalystic pyrolysis has reduced the coal-tar middle oil content of combustion gas; Be the most effective, state-of-the-art at present method, in large and medium-sized vapourizing furnace, be used gradually.In catalytic pyrolysis, most critical be the problem of selecting for use of catalyzer, a large amount of experiment proofs; A lot of materials all have katalysis to coke tar cracking, as: Ni base and heavy oit pyrolysis catalyzer, they are active high; Effective, existing very high cleavage rate in the time of 700 ℃, but their costs are higher; Carbon deposit causes its inactivation again easily, in general biomass gasification technology, is difficult to use.
