The present invention relates to a kind of dual rotary sealing valve biomass feeding system and feeding methods.There are feeding system blockings for existing biomass feeding system, most of biomass power generation system is required to the continuity of feed, if causing blockages, it will cause biomass incinerator or the even blowing out of biomass gasifying furnace operating condition fluctuation, feeding system leakproofness is bad, very likely in producer the phenomenon that high temperature gases recirculating to feeding system, and then biomass material is lighted, destroy feeding system by fire or even exploded.Present invention composition includes: level-one rotary seal valve (1), the outlet of the level-one rotary seal valve and the entrance of surge chamber (2) pass through flanged joint, the outlet of the surge chamber and the entrance of second level rotary seal valve (4) pass through flanged joint, the surge chamber side is equipped with pressurising hole (3), the pressurising hole is communicated with the surge chamber, and pressurized gas is air or nitrogen.The present invention is used for dual rotary sealing valve biomass feeding system.
Description
Technical field:
The present invention relates to a kind of dual rotary sealing valve biomass feeding system and feeding methods.
Background technique:
Biomass generation is a kind of advanced generation technology of energy-saving and environmental protection, is divided into biomass direct combustion power generation by technology path
The mixed combustion generation technology of technology, biomass and Biomass Gasification Power Generation Technology, these three biomass generations give biomass
The stability of material system and safety have very high requirement, if blocking, high temperature gases recirculating etc. occurs in biomass feeding system
Problem, not only will affect the operation of biomass incinerator or biomass gasifying furnace, also will cause feeding system kindling, even explodes
Etc. safety accidents；
Existing biomass feeding system still has two problems: (1) feeding system blocks: most of biomass power generation system is equal
It is required that the continuity of feed will cause biomass incinerator or biomass gasifying furnace operating condition fluctuation if causing blockages
Even blowing out, causes irremediable loss to production；(2) high temperature gases recirculating: boiler frequent for some pressure oscillations,
Especially positive pressure furnace, if feeding system leakproofness is bad, it is most likely that high temperature gases recirculating showing to feeding system in producer
As, and then light biomass material, destroy feeding system by fire or even explode.
Summary of the invention:
The object of the present invention is to provide a kind of dual rotary sealing valve biomass feeding system and feeding methods.
Above-mentioned purpose is realized by following technical scheme:
A kind of dual rotary sealing valve biomass feeding system, composition includes: level-one rotary seal valve, and the level-one rotation is close
The entrance of the outlet and surge chamber of sealing valve passes through flanged joint, the outlet of the surge chamber and the entrance of second level rotary seal valve
By flanged joint, the surge chamber side is equipped with pressurising hole, and the pressurising hole is communicated with the surge chamber.
The dual rotary sealing valve biomass feeding system, the level-one rotary seal valve and the second level rotate
Sealing valve includes feed valve chest, and the feed valve chest is interior to be connected with one group of revolving vane, the rotation by central axis
Turn to be inlaid with gasket at the top of blade.
The dual rotary sealing valve biomass feeding system, revolving vane quantity described in one group are for 6 and uniform
It is distributed in the feed valve enclosure interior, the gasket material is polytetrafluoroethylene (PTFE), and what the pressurising hole entered fills
Body of calming the anger is air or nitrogen, and the pressurized gas is 5 ~ 15Kpa.
A kind of dual rotary sealing valve biomass feeding system and feeding method, this method comprises the following steps: being fed first
The material of system selects rice husk, biomass block, biological particles, and material uses after the blanking entrance entrance of material valve chest
Surge chamber pressurising and rotary seal valve dual-seal, pressurized gas are filled with surge chamber through pressurising hole, and buffering chamber pressure is higher than level-one
Rotary seal valve inlet pressure and second level rotatory sealing valve outlet pressure.
The utility model has the advantages that
1. the present invention is a kind of dual rotary sealing valve biomass feeding system, mainly system is simple and reliable, and feed is stablized, and uses
The environmental protection material such as rice husk, biomass block, biological particles, the material do not generate the sundries of heat without other, are stale-proof
Boiler is lost, the service life of biomass feeding system is able to extend.
2. the system sealing that the present invention uses is good, surge chamber pressurising and rotary seal valve use dual-seal, are suitable for
To the higher positive pressure feeding system of sealing requirements, avoid in high temperature gases recirculating producer high temperature gases recirculating to feeding system
Biomass material is lighted, the thing that feeding system explodes is destroyed by fire and occurs.
3. the present invention uses two-stage rotary seal valve, the dual-seal of charging, feed is realized, and one is accumulated in surge chamber
Quantitative material forms material envelope, meanwhile, maintain buffering room pressure to be higher than feed by the pressurized gas that pressure is 5 ~ 15Kpa
Mouthful, guarantee the leakproofness in entire feed process, while this biomass feeding system can guarantee the continuity of feed, Bu Huifa
The phenomenon that raw feeding system blocking.
4. being inlaid with the gasket of polytetrafluoroethylene (PTFE) material at the top of revolving vane of the invention, the gasket of the material can
It is close with the sealing of feed valve inner walls, and frictional force is small, can make revolving vane rotation flexibly, it will not be because of material card
Stagnant phenomenon.
