Abstract
The invention relates to a feeding device, in particular to a spiral feeder used for fluidized-bed-type fast biomass pyrolysis. A storage bin is arranged above an air seal machine, material in the storage bin is conveyed into the shell of the feeder by virtue of the air seal machine, and biomass is continuously pushed into a fluidized bed reactor by virtue of an auger arranged in the shell. By virtue of mechanical sealing of the air seal machine and pressure separation and air locking of material filled in a conveying pipe, the feeder does not generate back spraying phenomenon; a stirring bar member is arranged in the storage bin, and power is provided for the stirring bar member while the air seal machine rotates to discharge material, so that the stirring bar member moves up and down and stirs the material, and phenomena of bridging, hanging on the wall and the like can be avoided; meanwhile, a variable frequency motor is connected with a gear transmission box to provide power for the auger and the air seal machine, and feed rates of the auger and the air seal machine are guaranteed to be consistent by virtue of speed ratio.
Description
Technical field
The present invention relates to a kind of feeding unit, particularly a kind of feeding screw that is used for biomass fluid bed fast pyrogenation.
Background technology
China's biomass energy is very abundant, and present national agricultural crop straw can obtain about 6.87 hundred million t every year, and about 60% can recovery energy, promptly has every year 4.2 hundred million t stalks to can be used as biomass material approximately, amounts to about 2.1 hundred million t standard coal equivalents; The forestry residuum can obtain about 1.25 hundred million t every year, amounts to about 7,125 ten thousand t standard coal equivalents.It is predicted that China can develop the biomass resource amount and can reach 1,500,000,000 t at least to the year two thousand fifty.Effective utilization to biomass can not only solve energy problem, and can solve environmental problem, at aspects such as energy-saving and emission-reduction, reduction carbon emission, energy recovery good effect is arranged.The fluidized bed type fast pyrolysis technology can convert the biomass of low energy densities into high-grade bio oil and other energy product, to produce fuel or Chemicals, is considered to one of the most potential biomass energy utilization technologies.
In the biomass fast pyrogenation process, must guarantee that material gets into fluidized-bed reactor continuously, equably, and require feeder and fluidized-bed reactor strict seal.Characteristics such as density is little because biomass have, the slope of repose is big, flowability difference are easy to occur problems such as bridging, wall built-up, thereby cause reinforced instability or stop feed in the feed bin in reinforced process.Biomass fluid bed fast pyrogenation system is a positive pressure system, causes the hot gas flow in the reactor drum to be overflowed if seal bad meeting, and formation is regurgitated, and makes material be difficult to get into reactor drum.
Prior biological matter feeder can't thoroughly solve owing to problems such as the bridge formation that reasons such as biomass have that density is little, the slope of repose is big, mobile difference cause, wall built-ups.Simultaneously, prior biological matter feeder can not guarantee continuously, evenly prevent to regurgitate in the charging.These two kinds of factors to a great extent limit the development of biomass fluid bed fast pyrolysis technology.
Summary of the invention
The objective of the invention is in order to overcome the various deficiencies that existing biomass feeder exists, proposed a kind ofly not only can avoid charging smooth but also can prevent the feeding screw that is used for biomass fluid bed fast pyrogenation regurgitated.
The present invention realizes through following technical approach: feeder housing, air sealer, feed bin vertically connect through flange; Feeding packing auger is positioned at the feeder housing; Biomass push fluidized-bed reactor by auger again in air sealer gets into the feeder housing, guaranteed the continuous, even of charging.Simultaneously, the material envelope at a distance from pressing material in lock wind and the feeder housing of air sealer has played anti-effect of regurgitating; The agitator arm member that is positioned at feed bin is made up of straight agitator arm, curved agitator arm, connecting rod, contact, and an end is connected with bin wall through bolt, and the other end connects spring member.Straight agitator arm is connected by guide rail with curved agitator arm, welds connecting rod on the agitator arm, and the connecting rod two ends are contact; The lower end of curved agitator arm contacts with the blade of air sealer, through rotatablely moving to the agitator arm member provides power of air sealer, the agitator arm member is moved upward and the extrusion spring member.When the lower end of agitator arm member broke away from the blade of air sealer, spring member was pushed the agitator arm member to be about to the blade that rotation is come to, through the stirring material that moves up and down of agitator arm member, avoided occurring phenomenons such as bridging, wall built-up; Frequency modulation motor driven gear wheel box is that auger and air sealer provide power, guarantees that simultaneously the inlet amount of the two is consistent; Feeder housing and speed-changing gear box are through being bolted on the base.
Irregular, different angles layout that said connecting rod becomes guarantees good disturbance effect.
Said contact is the aluminium ball, is welded on the connecting rod two ends.
Described spring member is inner to be the thrust spring.
Compared with prior art, because air sealer has the favorable mechanical sealing function, the material of filling between auger and feed-pipe can play the effect of material envelope, and that has realized fluidized-bed reactor and feeding screw locks wind at a distance from pressing; Owing in feed bin, be provided with the agitator arm member, with the rotation of air sealer blade power is provided, promptly do not need the extra power that provides to realize the disturbance of material in feed bin again, avoid occurring phenomenons such as bridging, wall built-up.
