At the inner sleeve plug-in type is mounted in outer tube and interface connects by welding above, and guarantees inner sleeve
Manage coaxial with outer tube, the gas feed section includes four gas feeds, and with the outer straight pipe and interior straight pipe it
Between the circular passage cooperation that is formed, it can be achieved that gas Uniform Flow in circular passage, the cone angle of the contract section is less than outer
The cone angle of contraction section forms tapering type circular passage, so that the gas at throat's necking that tapering type circular passage lower end is formed
Flow velocity is higher, and the outer flared section uses downward divergent structure, reduces the pressure loss, it is ensured that dispenser outlet maintains positive pressure.
Rice husk, biology can be selected in a kind of feeding method of injection type biomass feeding apparatus, the first material of feeding system
The environmental protection bulk cargo such as matter briquetting, biological particles, biomass bulk cargo feed inlet above inner sleeve enter charging gear, air or
Nitrogen enters charging gear by gas feed section, by the gas flow and pressure head of regulating gas inducer, changes throat's contracting
Vacuum magnitude at mouthful realizes that biomass feed inlet and the pressure difference between aditus laryngis are adjustable, is advantageously implemented different furnace pressures
Under the conditions of biomass steady and continuous feed.
The beneficial effects of the present invention are: by using technical solution of the present invention
1. simple and reliable for structure, applicability is extensive, is applicable to a variety of environmental protection such as rice husk, biomass block, biological particles and dissipates
Material.
2. the device carries out biomass feeding using gas injection principle, machine existing for traditional biomass feeding system is avoided
The problems such as tool bite and material are wound, it can be achieved that biomass bulk cargo steady and continuous is fed, improve feeding system service life and
Operational safety.

Specific embodiment
Below in conjunction with attached drawing, the present invention is described in further detail: the present embodiment is being with technical solution of the present invention
Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As Figure 1-Figure 4, a kind of injection type biomass feeding apparatus involved in the present embodiment, including inner sleeve 1 with
Outer tube 2, the inner sleeve 1 are used as biomass feed pipe, are connected from top to bottom by interior straight pipe 3,4 integral type of contract section
Structure, can directly with biomass bulk cargo belt conveyor cooperate complete charging, the outer tube 2 from top to bottom by gas feed section 5,
Outer straight pipe 6, outer contraction section 7 and 8 integral type of outer flared section connect and compose, and 1 plug-in type of inner sleeve is mounted in outer tube 2
And interface connects by welding above, and guarantees that inner sleeve 1 and outer tube 2 are coaxial, the gas feed section 5 is wrapped
The circular passage for including four gas feeds, and being formed between the outer straight pipe 6 and interior straight pipe 3 cooperates, it can be achieved that gas
Body Uniform Flow in circular passage, the cone angle of the contract section 4 are less than the cone angle of outer contraction section 7, form tapering type annular
On the one hand channel makes gas flowing more uniform, on the other hand can increase gas flow rate, so that under tapering type circular passage
Hold gas flow rate at the throat's necking formed higher, according to bernoulli principle it is found that larger negative pressure can be formed at throat's necking, with
Biomass feed inlet forms larger pressure difference, avoids biomass from occurring fluffy material phenomenon in inner sleeve 1, to be conducive to biomass
