Description
Technical field
The present invention relates to a kind of biomass gasification and gas-supply coproduction electricity, charcoal, heat, the process of fertilizer, belong to biomass
Energy field.
Background technology
Under the dual-pressure of the energy and environment, the regenerative resource of Devoting Major Efforts To Developing cleaning has turned into pendulum in countries in the world political affairs
A very urgent world subject in face of mansion.Biomass energy is compared with other new energy, have it is renewable, pollution less,
Can transport and store, with present energy industry most compatibility the features such as, thus especially attract attention.China is that an agricultural is big
State, agricultural-forestry biomass aboundresources, enormous amount, variety diversity.Under the Policy Background of advantage, biomass recycling use
Significant progress is obtained in China, but also produces technique, many problems on equipment simultaneously.
Biogas is turned to a kind of method of thermochemical study in biomass recycling use, and Duo Suo colleges and universities enter at home
Further investigation is gone.People sequentially develop many gasifying electricity generation techniques and equipment.Make a general survey of current biomass recycling gas
Elelctrochemical power generation technique and equipment：Product is single, and economic benefit is low；Using system for wet purification, water pollution is produced；It is not thorough due to purifying
Bottom is poor using internal combustion engine and gas turbine generating system stability.Han Wenke such as Lin Yuan Science and Technology Development Co., Ltd.s et al. develops
Patent《Scale fixed bed biomass gasification power generation technique and complete set of equipments》, Taiwan Huang Jia sheng, a reed pipe wind instruments et al. exploitation patent《One
Kind biomass energy circulation electrification technique and electricity generation system》, Kunming electricity Yan New Energy Technology Co., Ltd.s《Biomass energy gasification is sent out
Electric installation》：Product is single, increases depth-averaged model technique simultaneously more using wet purification heat loss, is generated electricity using internal combustion engine, surely
Qualitative difference.
Gasifying stalk power generation project on Current Domestic, use following technique：Biomass material pre-processes（Chip, do
The dry moisture content that arrives is below 20%）+ fixed bed or fluid bed+gas cleaning plant+internal combustion engine generate electricity（Gas turbine）.These gas
Elelctrochemical power generation technique only has generating not have charcoal product；Contain dust and Jiao in these runnings in the combustible gas of gasification furnace output
Oil, deep purifying must be carried out to combustible gas by being generated electricity for internal combustion engine, and presently preferred combustible gas purifying mode is washing power-up
Jiao is caught, electric tar requires to oxygen content in combustion gas, security incident may occur Ru exceeded, this causes electric tar method not push away
It is wide to use.Combustible gas passes through water washing cleaning, eliminates most dust and combustible gas really, but also leaves a small amount of tar,
The a small amount of tar in this part has had a strong impact on the operation of internal combustion engine generator so that internal combustion engine generator stability, efficiency decline and safeguarded
Expense improves, special scale online generating can not stable operation be difficult to popularization and application；This handicraft product is single, economic benefit
Difference.
The content of the invention
Proposed by the present invention is a kind of biomass gasification and gas-supply coproduction electricity, charcoal, heat, the process of fertilizer, and its purpose is intended to
Solves drawbacks described above existing for prior art, without that to being dried outside biomass stove, Diversified Products can be produced, improve economic effect
Benefit, system is stable, environmental protection, meets to adapt to the requirement that large-scale promotion uses.
The technology of the present invention solution：A kind of biomass gasification and gas-supply coproduction electricity, charcoal, heat, the process of fertilizer, using certainly
Dry, spray-moving type Poly-generation gasification installation, fuel of the hot combustion gas as boiler made from gasification, Steam Actuation vapour caused by boiler
Turbine generates electricity, while obtains electricity, charcoal, heat, thick fertile four products, and concrete technology step includes as follows：
1）The collection of biomass material, chip to 5cm or so；
2）It is more to be admitted to self-desiccation, spray-moving type under Belt Conveying, elevator effect for biomass material
In coproduction gasification installation, biomass material produces combustible gas in 600-800 DEG C of condition gasification, and flammable gas calorific value is
1100-1300Kcal, 300 DEG C or so of temperature；
3）By thick fertile collector, fertilizer vinegar liquid is trapped within thick fertile collector the hot combustion gas that 300 DEG C or so of temperature；Institute
The thick fertile collector stated is a kind of labyrinth settler；
4）After hot combustion gas is quickly through thick fertile collector, it is sent directly into burner and supplies gas fired-boiler, combustion gas is in boiler internal combustion
Burn and produce medium pressure steam, medium pressure steam（435℃、3.43Mpa）, promote steam turbine to generate electricity, steam turbine discharge
Steam waste heat is used for heating;
5）After charcoal cooling is collected, Belt Conveying to forming machine, charcoal for roasting, industrial charcoal etc. are machined to by forming machine；
6）Boiler afterheat is heated by air preheater to air, and hot-air is sent into gasification furnace by air blower.
Advantages of the present invention：
1）This technique productions electricity, charcoal, heat, fertile four products, diversity product, improve economic benefit.
2）Raw material self-desiccation system is provided with using gasification installation, for the raw material of moisture content 50% or so, it is not necessary to raw material
Dry, self-desiccation can be carried out using gasification installation reative cell heat, adaptability to raw material is wider.
3）Spray-moving type gasification system so that flammable air pipe Blower-free, gasification furnace security improves, maintenance rate reduces, behaviour
Make simple.
4）Using hot combustion gas burning boiler, the thermal efficiency greatly improves.
5）Electricity generation system provides Steam Actuation steam turbine power generation by gas fired-boiler, and equipment stably greatly improves, beneficial to scale
Metaplasia is produced.
