Summary of the invention
The present invention needs the problem solved to be overcome the deficiencies in the prior art, quantitative, closed type feeding device that a kind of biomass garbage malleation gasifies are provided, the maximum feature of the present invention is that feed is smooth and easy, good airproof performance between feeding device and vapourizing furnace, can not cause security incident.
Technical scheme of the present invention:
Biomass garbage closed type metering device of the present invention is shown in accompanying drawing 1, by vertical elevator (1), feed bin (2), dosing mechanism (3), material blanking tube (4), duplex three thrusters (5), hydraulic type thruster (6), hermatic door (7). vapourizing furnace (8) is formed.
The using method of biomass garbage closed type metering device of the present invention utilizes vertical elevator (1) that biomass garbage is transported to feed bin (2) from underground stockpile, feed bin (2) be sealing and with tapering, feed bin (2) connects dosing mechanism (3) below, dosing mechanism (3) utilizes equal-volume method of carrying biomass garbage to be transported to material blanking tube (4), the bottom of material blanking tube (4) is connected with duplex three thrusters (5), hydraulic type thruster (6), finally utilize the thrust of duplex three thrusters (5) or hydraulic type thruster (6) to be opened by hermatic door (7) biomass garbage is transported in vapourizing furnace.
Biomass garbage closed type metering device of the present invention is applicable to the biomass garbage of delivery size at 2-50mm.
Biomass garbage closed type metering device dosing mechanism (3) of the present invention sees accompanying drawing 2, be made up of pneumatics and two quantitative boxes, two kinds of dissimilar biomass garbages can be carried according to the size difference of biomass garbage simultaneously, the effect Shi Shi dosing mechanism of pneumatics moves reciprocatingly, and biomass garbage is transported to material blanking tube (4) respectively.
The volume of biomass garbage closed type metering device material blanking tube (4) of the present invention is 1.5-2 times that in dosing mechanism (3), quantitative box body is long-pending, object be to ensure the sealing of whole feeding system and feed smooth and easy, prevent owing to occurring getting stuck or blockage problem in course of conveying, thus affect stopping property and the security of feeding system.
Biomass garbage closed type metering device duplex of the present invention three thrusters (5), hydraulic type thruster (6), according to the size difference of biomass garbage, two kinds of different biomass garbages can be carried to enter in vapourizing furnace simultaneously, jointly gasify, thus improve gasification efficiency; Duplex three thrusters (5) and hydraulic type thruster (6) end are equipped with hermatic door, and are inclined upwardly when installing, and the inflammable gas in vapourizing furnace can be avoided like this to overflow, thus initiation feed bin is on fire and detonation safety problem; Duplex three thrusters (5) are applicable to the conveying of less, the uniform biomass garbage of size; It is comparatively large that hydraulic type thruster (6) is applicable to size, random biomass garbage.
The present invention compared with prior art its beneficial effect is:
Use equal-volume dosing mechanism to carry out biomass garbage conveying, be conducive to biomass garbage gasifying process parameter stability; Use the volume difference of quantitatively box and material blanking tube in dosing mechanism, effectively prevent and get stuck, carry the problems such as not smooth.Use the devices such as duplex three thrusters, hydraulic type thruster and hermatic door, achieve good sealing, avoid feed bin and catch fire and the security incident such as detonation.Solve the maximum bottleneck problem in current biomass garbage gasification feeding technology and technical barrier.
