Abstract
The invention discloses an exhaust hood for a biomass energy converter. The exhaust hood for the biomass energy converter comprises a hood body (1) in which a cavity is formed, and is characterized in that: a plurality of grooves (3) are distributed at the periphery of an outer surface of the hood body (1); and exhaust holes (5) are reserved on side walls (4) of the grooves (3) and are communicated with the cavity in the hood body (1). The exhaust holes are reserved on the side walls of the grooves formed on the outer surface of the hood body, so wind enters a combustion chamber in a centrifugal radiation shape to form rotary wind, and a combustible material in the combustion chamber can be combusted sufficiently; the opening direction of the exhaust holes is changed to the horizontal direction from the conventional vertical direction, so the blockage due to dust is avoided; and through the structure, the gas generation performance is greatly improved.
Description
Technical field
The present invention relates to a kind of but the organic fuel of biology be changed into the biomass energy conversion system of combustible gas, specifically be meant a kind of exhaust hood for biomass energy converter.
Background technology
Along with China's rapid economy development, resource supply and demand breach such as oil, Sweet natural gas, coal increase year by year, and price also rises steadily, and many peasant households are reluctant to also not consume expensive coal gas and coal.Therefore, existing market a kind of biomass energy that improves the renewable energy utilization rate occurs and transforms roasting kiln, the rural area can be used not only clean but also cheap new forms of energy.But prior biological mass-energy converter is because the wind apparatus that looses is structural unreasonable, its diffusing wind weak effect.In use: wind direction can only perpendicular flow when loosing wind apparatus for the wind that gas blower produced, be positioned at high-rise burning material vertical combustion down the wind like this in the biomass energy converter combustion chamber, and lower curtate and high-rise surrounding edge the burning material fail all burnings, it is low to be directed at biomass energy converter efficient, and the material burning just produced naked light in 20-40 minute and can not work.And the air-guiding hole of traditional diffusing wind apparatus towards, when the burning material easily stops up at the carbon ash that high temperature reflection process produces, directly influence the work of biomass energy converter.
Summary of the invention
The objective of the invention is to above-mentioned exhaust hood for biomass energy converter is improved, a kind of effective, not susceptible to plugging exhaust hood for biomass energy converter of wind simple in structure, diffusing is provided.
To achieve these goals, the technical solution used in the present invention is: exhaust hood for biomass energy converter, include cover body, the inside of cover body is a cavity, along circle distribution a plurality of grooves are arranged on the outside surface of described cover body, the sidewall of described groove is provided with the wind hole of loosing, and this diffusing wind hole communicates with the intravital cavity of cover.
The outside surface of described cover body constitutes an impeller shape structure, and a sidewall of described groove is vertical with the bottom surface, and the corresponding sidewall of opposite side is an arc.
Described cover body is to be made by metal sheet or concrete or other high temperature material.
The outside surface of described cover body is provided with ring and wind-guiding outer shroud in two concentric wind-guidings.
Beneficial effect of the present invention: because the wind hole of loosing is located on the recess sidewall of cover body outside surface, can makes wind be centrifugal the thanking property of putting and enter formation rotation wind in the combustion chamber, make the comprehensive abundant burning of burning material in the combustion chamber; Owing to changed the opening direction in diffusing wind hole, laterally avoided the dust phenomenon of blocking by original vertically having made into; This structure has been improved gas generation property greatly; Cover body is provided with air guide ring can allow wind along ring rotation, can make fully burnings equably such as various burning materials that volume varies in size such as twigs, leaf, Pericarppium arachidis hypogaeae, husk, rice bran.

Among the figure: 1, cover body; 2, cavity; 3, groove; 4, sidewall; 5, diffusing wind hole; 6, corresponding sidewall; 7, ring in the wind-guiding; 8, wind-guiding outer shroud.
Embodiment
Embodiment 1: as shown in Figure 1 and Figure 2, exhaust hood for biomass energy converter includes cover body 1, and the inside of cover body is a cavity 2, along circle distribution a plurality of grooves 3 is arranged on the outside surface of described cover body 1, constitutes an impeller shape structure; The sidewall 4 of described groove 3 is provided with the wind hole 5 of loosing, and this diffusing wind hole 5 and cover body 1 interior cavity 2 communicates.One sidewall 4 of described groove is vertical with the bottom surface, and the corresponding sidewall 6 of opposite side is arcs.Described cover body is to be formed by concrete prefabricated.
Embodiment 2: as shown in Figure 3, exhaust hood for biomass energy converter includes cover body 1, and the inside of cover body is a cavity, along circle distribution a plurality of grooves 3 is arranged on the outside surface of described cover body 1; The sidewall 4 of described groove 3 is provided with the wind hole 5 of loosing, and this diffusing wind hole 5 and cover body 1 interior cavity communicates.Described cover body is to be made by metal sheet.
Embodiment 3: as shown in Figure 4, exhaust hood for biomass energy converter includes cover body 1, and the inside of cover body is a cavity, along circle distribution a plurality of grooves 3 is arranged on the outside surface of described cover body 1; The sidewall 4 of described groove 3 is provided with the wind hole 5 of loosing, and this diffusing wind hole 5 and cover body 1 interior cavity communicates.Described cover body is to be formed by concrete prefabricated.The outside surface of cover body 1 is provided with ring 7 and wind-guiding outer shroud 8 in two concentric wind-guidings.
Embodiment 4: as shown in Figure 5, exhaust hood for biomass energy converter includes cover body 1, and the inside of cover body is a cavity, along circle distribution a plurality of grooves 3 is arranged on the outside surface of described cover body 1; The sidewall 4 of described groove 3 is provided with the wind hole 5 of loosing, and this diffusing wind hole 5 and cover body 1 interior cavity communicates.
Working process: the exhaust hood of biomass energy converter, bottom and vent-pipe are tightly connected, and the wind that produces when gas blower (regulating wind energy conversion system for three grades) enters in the combustion chamber of biomass energy converter from air-guiding hole by the exhaust hood bottom cavity.Because it is leaf that cover body is fan, make wind diffusion rapidly from different perspectives, burning material in the combustion chamber obtains abundant high temperature thermalization generation high-temperature flue gas and enters smoke chamber in the secondary air distribution like this, after high-temperature flue gas in the smoke chamber enters the indoor catalyst-assembly of gas reforming by smoke hole, the inflammable gas that produces enters the gas reforming chamber then, uses to stove and accessory by the inflammable gas pipe-line transportation.
