The invention relates to a semi-coke diffuser in a coal-gas gasification system. The coal-gas gasification system comprises a cyclone separator and a pyrolysis gasification bed, wherein the semi-coke diffuser is arranged under the cyclone separator and above the pyrolysis gasification bed; a conical air distribution body is arranged in the pyrolysis gasification bed; the semi-coke diffuser consists of an upper chamber, an intermediate chamber and a lower chamber which are communicated one another; the upper chamber is a big end up conical chamber, part semi-coke separated from the cyclone separator partially falls on the conical air distribution body of the pyrolysis gasification bed through the semi-coke diffuser, partially falls on the conical surface of the upper chamber, slides down along the conical bevel and spreads above the pyrolysis gasification bed under the inertia effect. According to the semi-coke gasifiction system, the semi-coke falling from the cyclone separator is collected to the intermediate chamber through the big end up cone of the upper chamber, falls into the lower chamber from the intermediate chamber, and falls onto the conical air distribution body in the pyrolysis gasification bed, so that the semi-coke can be burnt once again on the pyrolysis gasification bed and is further and completely gasified.
Description
Technical field
The present invention relates to coal gas equipment technical field, specially a kind of whirlwind being arranged in coal gas gasification system point
Semicoke collecting-distributing device between reason device and pyrolytic gasification bed.
Background technology
Cyclone separator in the ciculation fluidized bed gasification system of coal gas, is the high-temperature coal for separating from gasification furnace out
Separation equipment containing solid coal ash particles in gas.It adopts vertical drum structure, and inside is divided into cyclone separator exocoel and rotation
Wind interior separator cavity.The coal gas of high temperature and solid coal ash particles for flowing out is exported from gasification furnace coal gas of high temperature, from cyclone separator
Upper portion side wall entrance is introduced tangentially into cyclone separator exocoel and forms rotary motion, makes the coal ash solids with larger centrifugal inertial force
Granule gets rid of to outside wall surface and separates, so as to realize the purpose of solid particle and coal gas of high temperature gas solid separation.But in actual separation process
In, due to the air velocity of coal gas of high temperature it is relatively low, the centrifugal inertial force that tangential rotation is formed not enough, often prevent solid particle from
Separation is thrown out of, causes still to contain substantial amounts of coal ash dust granules in the coal gas of high temperature flowed out from cyclone separator.Therefore, pass
The ciculation fluidized bed gasification system of system coal gas, needs the uncombusted dust granules coal that will be flowed out from gasification furnace, in gasification furnace and rotation
Tens of times of cyclic, could improve constantly the efficiency of carbon con version of feed coal between wind separator.Obviously, such cycle gasification mode
Its gasification efficiency is extremely low, carbon gasification rate is not high.It is 201710048002.1 in Chinese Patent Application No. to solve the above problems
Patent of invention in, disclose " a kind of pyrolytic gasification bed for being arranged on cyclone separator bottom ".It is under cyclone separator
Portion arranges pyrolytic gasification bed, the coal ash solid particles that cyclone separator is separated, without fluidized-bed gasification furnace circulating air
Change, and pass through the further combustion and pyrolysis gasification of pyrolytic gasification bed, it is achieved thereby that completing raw material in circle fluidized-bed gasification furnace
The desulfurization of coal and preliminary gasification, feed coal are completed on pyrolytic gasification bed and are fully and completely gasified the purpose of after-flame.Concrete structure is：
Pyrolytic gasification bed is arranged on cyclone separator bottom, and pyrolytic gasification bed is provided with taper cloth wind body, taper cloth wind body bottom with it is outer
The gasifying agent pipeline connection in portion is communicated, and the coal ash solid particles for falling is separated from cyclonic separation exocoel and is degenerated in pyrolytic gasification bed
On taper cloth wind body.Wherein solid particle is degenerated in what manner on the taper cloth wind body of pyrolytic gasification bed, is to determine heat
Can solution gasifier bed by the key of the complete pyrolytic gasification of coal ash solid particles.Very obviously, separate from cyclonic separation exocoel and fall
If coal ash solid particles can equably degenerate and be distributed on the taper cloth wind body of pyrolytic gasification bed, coal ash solid particles combustion
Burn most thoroughly, the gasification efficiency of pyrolytic gasification bed and efficiency of carbon con version are certainly optimal.Therefore, a kind of the effect above of realizing is designed
Device is most important.
The content of the invention
It is an object of the invention to provide a kind of coal ash solid particles that fall can cyclone separator, are uniformly distributed in heat
Semicoke collecting-distributing device on solution gasifier bed taper cloth wind body, the thorough burning for coal ash solid particles provides condition, to improve gasification
Efficiency and efficiency of carbon con version.
To achieve these goals, the present invention takes technical scheme below to implement：In a kind of coal gas gasification system half
Burnt collecting-distributing device, described coal gas gasification system includes：Cyclone separator and pyrolytic gasification bed, described semicoke collecting-distributing device is placed in
The bottom of cyclone separator, the top of pyrolytic gasification bed；Taper cloth wind body is provided with described pyrolytic gasification bed, its feature exists

Described semicoke collecting-distributing device is made up of the chamber of epicoele, lumen, three sections of intercommunications of cavity of resorption, the upper end of lumen and the lower end of epicoele
It is connected, the lower end of lumen is connected with the upper end of cavity of resorption；
The epicoele is up big and down small taper chamber, and from the semicoke that cyclone separator is isolated, a part is collecting and distributing through semicoke
Device is fallen on the taper cloth wind body of pyrolytic gasification bed, and a part falls on the conical surface of epicoele, and is glided along cone inclined-plane, and in inertia
In the presence of to pyrolytic gasification bed taper cloth wind body top surrounding send out；
The lumen is up-small and down-big back taper fluid chamber, and cavity of resorption is upper arch hemisphere chamber；
Described semicoke collecting-distributing device is respectively arranged at two ends with adpting flange, and the adpting flange of upper end is by many bolts and cyclonic separation
The adpting flange fixed seal connection of device lower end, the adpting flange of lower end passes through the connection of many bolts and pyrolytic gasification bed upper end
Flange fixed seal connection.
The semicoke fallen from cyclone separator is brought to lumen by the up big and down small conical surface of epicoele by the present invention, then by
