Description
Technical field
The gasification reactor apparatus of biological energy source is the present invention relates to the use of, more particularly, to the following gas using biological energy source
Change reaction unit：Solid biological energy source is subjected to heat, chemically energy conversion and generates gaseous hydrogen, carbon monoxide, methane etc.
Forming gas, and such forming gas is utilized as to the heat source of boiler or the fuel of internal combustion engine, so as to produce electric power.
Background technology
Usually, gasification refers to by heat, chemically solid material is generated as gaseous state by energy conversion method
Material forming gas, as the applicable object of gasification technology, can mainly enumerate coal, discarded object, wooden biological energy source (rice
Chaff, cornstalk, sawdust, sawdust) etc..
Here, gasification process is broadly divided into fixed bed mode and fluidized bed mode, fixed bed mode is subdivided into formula gas
Change method, downdraft mode gasification process, convection type gasification process, fluidized bed mode can be divided into circular flow gasification process, gasification
Bed fluidized bed gasification method etc..
Wherein, to formula gasification process it is to put into solid material from upside on, and is supplied to the direction opposite with solid material
The mode of gasification oxidant.
That is, arid region (Drying zone), thermal decomposition region are divided on the upside of input solid material
(Pyrolysis, Distillation zone), reduced zone (Reduction zone), oxide regions (Combustion
zone)。
In the upper gasification process to formula, the air as oxidant is mainly fed into the upside of input raw material from lower part,
Therefore high to the heat transfer efficiency of input solid material, outlet temperature is the relatively low temperature of 250~300 degrees Celsius of degree,
But in the characteristic of process, since the tar content in forming gas is high, so as to replace technology mainly as the heat source of boiler etc.
And use.
Secondly, downdraft mode gasification process is the incidence of the solid material side parallel with the incidence composition of air
Formula.
That is, arid region (Drying zone), thermal decomposition region are divided on the upside of input solid material
(Pyrolysis, Distillation zone), oxide regions (Combustion zone), reduced zone (Reduction
Zone), the incidence as the air of oxidant is the direction identical with the incidence of solid material.
In downdraft mode gasification process, the mistake in the arid region on the top by generation forming gas and thermal decomposition region
Cheng Zhong, from the oxide regions of lower part can not achieve solid fuel between sufficient heat transfer, cause the thermal efficiency relatively low, only form root
According to the heat transfer of radiant heat, thus the discharge temperature of forming gas is 700~750 degrees Celsius of higher temperature.
But in downdraft mode gasification process, the content of the tar in forming gas is less, and (tar reduction degree is
95~99% degree), therefore by downdraft mode gasification process be the hair that can be directly thrown into internal combustion engine the forming gas that generates
Motor and the degree that can be used, the cogeneration of heat and power thus, it is possible to used with heat and electricity.
However, convection type gasification process can be described as it is mixed with downdraft mode gasification process to formula gasification process, from side
Face puts into oxidant, and the characteristic that there is the tar destruction rate in forming gas to decline, is primarily adapted for use in rice chaff, sawdust etc. so
Low density solid material gasification.
Therefore, it have developed the gasification installation using the relatively low downdraft mode gasification process of tar content in recent years.
But in the gasification installation using such downdraft mode gasification process, solid material and the sky as oxidant
The incidence of gas is identical, thus causes the heat transfer efficiency of solid material with air to each other to decline, therefore such as above-mentioned, is discharged
Forming gas sensible heat temperature it is higher.
Therefore, a kind of sensible heat that can not only utilize the higher forming gas of such temperature of real need research and development, and
And the gasification installation for possessing the biological energy source solid material of various species and character can also be widely used in.

More specifically, reactor upper body (110) are to include the 1st fire resisting parietal layer (111) and the knot of refractory walls inclined-plane (112)
Structure.
Inner peripheral surface of the 1st fire resisting parietal layer (111) from the lower part of arid region (101) along reactor upper body (110) and shape
As certain thickness.
Refractory walls inclined-plane (112) is dipped down towards inner shell (130) side in the upper end of the 1st fire resisting parietal layer (111)
Tiltedly formed, it is to make input biological energy source (108) to be successfully directed into lower part to set refractory walls inclined-plane (112)
Side and fall.
Also, more specifically, inner shell (130) is the structure for including reducing diameter part (132) and wide diameter portion (134).
Reducing diameter part (132) possesses from upside forms burning inclined-plane (131) with becoming narrow gradually, and wide diameter portion (134) is with from burning
The mode that the edge of the bottom on inclined-plane (131) extends and gradually broadens is formed.Here, oxide regions (103) are located at reducing diameter part
(132) and wide diameter portion (134) top, reduced zone (104) is formed at the lower part of wide diameter portion (134).
In the following, more specific description is carried out to the structure of reactor upper body (110) and inner shell (130).
First, the symbol description illustrated to the lower right side of Fig. 1 is as follows.

In input biological energy source (108)；And torque sensor (150), it while rotating carries out the quantity delivered of biological energy source (108)
Detection, at least one torque sensor (150) is separately installed with the upper and lower end of funnel (140).
When torque sensor (150) is detected by funnel (140) to have put into biological energy source (108), while rotation, one
While quantitative control in real time is carried out to the input amount of biological energy source (108).
In addition, air is to promote the oxidation put into the burning of the part of the biological energy source (108) of oxide regions (103)
Agent, oxidation is put to by one or all in the 1st air feeding assembly (200) and the 2nd air feeding assembly (300)
Region (103).In other words, it is the things such as wooden biological energy source, that is, rice chaff, cornstalk, sawdust, sawdust in input biological energy source (108)
During matter, if injection for biological energy source (108) completely burned air quantity delivered 20% to 35% degree (0.7~
0.8Nm3/ kg), therefore utilize the 1st air feeding assembly (200) described later.
In addition, input biological energy source (108) is the carbon such as coal and discarded object concentrates, high as petroleum compound etc.
