Abstract
The sleeved air seal set and sealing gland method of positive pressure biomass gasifying furnace feeding system.In recent years, biomass gasification technology reaches its maturity, and positive pressure biomass gasification technology has its unique advantage compared to Gasification at the negative pressure.But positive pressure gasification technology prevents the toxic easy burning fume anti-channeling of the positive pressure in furnace from entering feed pipe, causes to leak and be fed unsmooth problem since the positive pressure in furnace makes feeding system that need to carry out sealing.Present invention composition includes feed pipe (3), feedblock (2) are cased with outside the nozzle of the feed pipe, one group of cushion block (4) is lined between the feed pipe and the feedblock, form gap, the feedblock has one group of inert gas import pipe (1), and the inert gas import pipe is communicated with the nozzle of feed pipe by the gap.The present invention is applied to the sleeved sealing gland of positive pressure biomass gasifying furnace feeding system.
Description
Technical field:
The present invention relates to a kind of sleeved air seal set of positive pressure biomass gasifying furnace feeding system and sealing gland methods.
Background technique:
In recent years, biomass gasification technology reaches its maturity, and positive pressure biomass gasification technology has its unique excellent compared to Gasification at the negative pressure
Gesture.But positive pressure gasification technology prevents the positive pressure in furnace toxic inflammable since the positive pressure in furnace makes feeding system that need to carry out sealing
Flue gas anti-channeling enters feed pipe, causes to leak and be fed unsmooth problem.
Summary of the invention:
In order to overcome the above problem of the existing technology, the object of the present invention is to provide one kind to be used for positive pressure biomass gasifying furnace
The sleeved air seal set of feeding system.
Above-mentioned purpose is realized by following technical scheme:
A kind of sleeved air seal set for positive pressure biomass gasifying furnace feeding system, composition includes: feed pipe, feature
It is: is cased with feedblock outside the nozzle of the feed pipe, one group is lined between the feed pipe and the feedblock
Cushion block, forms gap, and the feedblock has one group of inert gas import pipe, the inert gas import pipe and feed
The nozzle of pipe is communicated by the gap.
The sealing gland method of the above-mentioned sleeved air seal set for positive pressure biomass gasifying furnace feeding system, passes through indifferent gas
The inert gas of certain speed is introduced positive pressure biomass gasifying furnace feeding system by body inlet tube, to avoid in positive pressure gasification furnace
Flue gas anti-channeling enters feeding system and guarantees the smoothness of feed, inert gas fed by the inert gas import pipe of surrounding in
Gap between feed pipe and casing carries out sealing gland to the nozzle of feed pipe using the pressure head and flow of inert gas.
Beneficial effects of the present invention:
The present invention is used for the sleeved air seal set of positive pressure biomass gasifying furnace feeding system, is mainly used for positive pressure gasification furnace feed
The sealing of system avoids flue gas anti-channeling.Inert gas channel is formed using feed pipe and the casing of outside, wherein surrounding is provided with
Cushion block avoids causing channel blockage due to expansion etc., inert gas is fed interior feed pipe and set by the pipeline of surrounding
Gap between pipe, using inert gas pressure head and flow carry out sealing gland, to avoid the flue gas anti-channeling in positive pressure gasification furnace into
Enter feeding system and guarantees the smoothness of feed.It is simple that advantages of the present invention is mainly reflected in structure fabrication, practical reliable, passes through choosing
Reasonable pressure head and flow are taken, can effectively ensure that sealing effect.
Detailed description of the invention:
Attached drawing 1 is main view of the invention.
Attached drawing 2 is the top view of attached drawing 1.
Specific embodiment:
Embodiment 1:
A kind of sleeved air seal set for positive pressure biomass gasifying furnace feeding system, composition includes: feed pipe 3, special
Sign is: being cased with feedblock 2 outside the nozzle of the feed pipe, is lined with one between the feed pipe and the feedblock
Group cushion block 4, formed gap, the feedblock have one group of inert gas import pipe 1, the inert gas import pipe with
The nozzle of feed pipe is communicated by the gap.The outlet muzzle of feedblock is in the outside of feed pipe nozzle, inert gas
Inlet tube is vertical with feed pipe.
Embodiment 2:
The sealing gland method of the above-mentioned sleeved air seal set for positive pressure biomass gasifying furnace feeding system, by inert gas into
The inert gas of certain speed is introduced positive pressure biomass gasifying furnace feeding system by mouth pipe, to avoid toxic in positive pressure gasification furnace
Easy burning fume anti-channeling enters feeding system and guarantees the smoothness of feed, is given inert gas by the inert gas import pipe of surrounding
Enter the gap between interior feed pipe and casing, sealing gland is carried out to the nozzle of feed pipe using the pressure head and flow of inert gas.
