The method utilizes the gasification technology, which converts the forestry and agricultural residues comprising wasted straws, sawdust, haulms, rice husks, bagasse, etc. into the flammable gas approaching the coal gas; after the dust and the tar of the flammable gas is removed by a purifier, the flammable gas is conveyed in a gas internal combustion engine or a gas turbine for generation. The invention has strong raw material adaptability, can dispose the biomass raw material of different types, and has the advantages of large production intensity, high gas heat value, little tar content, high gasification efficiency, strong load adaptability, easy start and stop, large adjustable range, stable operation, extremely high flexibility in scale. Furthermore, the generation scale depends on the quantity of the raw material and the requirement of the power, and can be designed and matched according to the requirement of the user.
Description
Technical field
The present invention is a kind of method of utilizing biomass power generation.
Background technique
Along with the continuous progress and the development of society, a large amount of uses of conventional fossil energy have brought serious day by day energy crisis and environmental pollution.How finding the discharging that substitutes conventional fossil energy and reduce various harmful wastes is the difficult problem that very urgently will solve now.Various living beings (comprising agriculture and forestry organic waste material and trade waste) are the reproducible energy of a kind of cleaning, utilize these living beings to generate electricity, and are the effective ways that solves an above-mentioned difficult problem.Use the mode of biomass power generation mainly based on direct burning at present, the mode of this direct burning, similar to traditional coal-burning power plant, its minimum installation scale is 24MW, demand to raw material is very big, be to satisfy the demand of power plant to raw material in certain collection transportation radius, main is that directly burning still brings great pollution to environment.
Summary of the invention
The objective of the invention is in order to overcome the defective that direct biomass burning generates electricity, invent a kind of various biomass materials are collected pretreatment after, in gasification oven, gasify the method for utilizing the inflammable gas that produces to generate electricity.
The objective of the invention is to realize as follows: the described method of utilizing biomass power generation comprises living beings gasification, gas purification, gas internal-combustion engine or gas turbine power generation, UTILIZATION OF VESIDUAL HEAT IN four parts:
One. the living beings gasification comprises feedworks and gasification installation:
Feedworks adopts screw feeder, power equipment is an electromagnetic adjustable speed motor, screw feeder both had been convenient to evenly charging continuously, can effectively gasification oven be sealed with outside completely cutting off again, make the gasification required air only enter gasification oven by the control of air intake machine, electromagnetic adjustable speed motor then can be regulated the living beings inlet amount arbitrarily;
Gasification installation can adopt the gasification oven of circle fluidized-bed gasification furnace or other continuously-runnings, it mainly is made of air intake machine, gasification oven and deslagging spiral, living beings generate inflammable gas through high temperature pyrolysis and gasification in gasification oven, the remaining ash in gasification back is then in time discharged out of the furnace by the deslagging spiral.
Two. gas purification
Gas needs just can be used for generating after purified treatment, gas-purification comprises dedusting, ash disposal and removes tar, multistage dedusting technology is adopted in gas purification: as inertial dust separator, cyclone separator, venturi scrubber, electric precipitation, through multistage dedusting, solid particle in the combustion gas and fine dust are cleaned totally substantially; Tar in the combustion gas adopts the way of absorption and washing to remove, and capital equipment is two spray aeration towers that are together in series.
Three. electricity generating device
Combustion gas internal combustion engine generator group or gas turbine are adopted in generating, and generator system can be made up of separate unit or many unit parallel connections according to the material quantity in the certain limit.
Four. residual heat using device
No matter be gas internal-combustion engine, or gas turbine, generating back discharge tail gas temperature is all between 500-600 ℃, if power generating equipment band air increases the gas pressurization system, the tail gas temperature all generally between 450-500 ℃, contains a large amount of callable energy, so increase waste heat recovering device behind fuel gas generation equipment in the tail gas, as exhaust heat boiler etc., can improve system effectiveness; In the living beings gasification power generation system, except power generating equipment tail gas has a large amount of waste heats, the fuel gas temperature of biomass gasifying furnace outlet is also very high, reach about 700-800 ℃, so the waste heat of this part gasification sensible heat and fuel gas generation equipment is combined, utilize exhaust heat boiler and superheater to produce steam, utilize steam turbine to generate electricity again.
Good effect of the present invention is as follows: adaptability to raw material of the present invention is strong, can handle different types of biomass material; Production intensity is big, the gas heating value height, and tar content is less, the gasification efficiency height; Load performance is strong, starts to stop easily, and regulation range is big, operates steadily; Have very high flexibility on the scale, the generating scale is decided by raw material quantity, need for electricity, can design according to user's needs and mate.
