Description
Technical field
The present invention relates to a kind of corollary equipment of coal gas recirculating fluidized bed, specially one kind is arranged under cyclone separator
The pyrolytic gasification bed in portion, belongs to coal gasification apparatus technical field.
Background technology
Cyclone separator in the ciculation fluidized bed gasification system of coal gas, is for separating the high-temperature coal 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
Particle 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, in causing from cyclone separator the coal gas of high temperature for flowing out, still contains substantial amounts of coal ash dust granules.To understand
Certainly the problems referred to above, the ciculation fluidized bed gasification system of traditional coal gas, need the uncombusted dust granules coal that will be flowed out from gasification furnace,
Tens of times of cyclic between gasification furnace and cyclone separator, therefore, traditional cyclone separator can only be by feed coal whirlwind
Separate and repeatedly circulate to send in gasification furnace and regasify burning, the efficiency of carbon con version of feed coal could be improved constantly.Obviously, so follow
Its gasification efficiency of ring gasification mode is extremely low, carbon gasification rate is not also high.
The content of the invention
It is an object of the invention to provide a kind of pyrolytic gasification bed for being arranged on cyclone separator bottom, it is intended to by this dress
Put the gasification efficiency and efficiency of carbon con version for improving the ciculation fluidized bed gasification system of coal gas.
The present invention is implemented by the following technical programs：A kind of pyrolytic gasification bed for being arranged on cyclone separator bottom, including
Cyclone separator and pyrolytic gasification bed, are provided with cyclonic separation exocoel and cyclonic separation inner chamber, from gas in described cyclone separator
Change the coal gas of high temperature rich in solid particulate matter that the outlet of stove coal gas of high temperature is flowed out, cut from the upper wall portions entrance of the cyclone separator
Rotary motion is formed to introducing in cyclonic separation exocoel, the coal ash solid particles with larger centrifugal inertial force is got rid of to outside wall surface
Separation falls, and the coal gas of high temperature after separation flows into lower road equipment vertically upward from cyclonic separation inner chamber；On the pyrolytic gasification bed
It is provided with taper cloth wind body, taper cloth wind body bottom is connected with the gasifying agent pipeline of outside and communicates, and taper cloth wind body bottom is provided with slag
Disk, it is characterised in that：
The pyrolytic gasification bed is arranged on the bottom of cyclone separator, and the coal ash solid particles for falling are separated from cyclonic separation exocoel
Degeneration is on the taper cloth wind body of pyrolytic gasification bed；
The cyclone separator bottom constitutes the pyrolytic gasification bed gasification furnace furnace chamber with cone shaped distributor upper space；
Coal gas solid particle on the taper cloth wind body further combustion heat under the gasifying agent effect that gasifying agent pipeline is introduced
Solution gasification；
Coal gas of high temperature after the bed pyrolytic gasification from pyrolytic gasification flows into lower road equipment through cyclonic separation inner chamber, after-flame coal
Slag falls into slag pan.
The present invention arranges pyrolytic gasification bed, the coal ash solids that cyclone separator is separated in the bottom of cyclone separator
Particle, without fluidized-bed gasification furnace cycle gasification, and passes through the further combustion and pyrolysis gasification of pyrolytic gasification bed, so as to realize
The desulfurization and preliminary gasification of feed coal are completed in circle fluidized-bed gasification furnace, feed coal is completed on pyrolytic gasification bed fully and completely
The purpose of gasification after-flame.
The present invention has new reasonable design concept, gasificating desulfurization good combination property, gasification efficiency and efficiency of carbon con version height etc.
Advantage.
Description of the drawings
