Air outlet holes are uniformly distributed in an ash tray shell of the ash tray mechanism for the biological gasification furnace, so that air entering from an air inlet at the bottom can be ensured to uniformly enter a furnace body of the gasification furnace, and the combustion efficiency is improved; simultaneously, ash on the ash tray can automatically drop, the problems of accumulation, blockage and the like of an ash bin can be avoided, and the service life is long.
Description
Technical Field
The utility model relates to an ash tray, in particular to an ash tray mechanism for a biological gasification furnace.
Background
With the rapid development of industry and the high-speed advance of urbanization process, energy is short, and the problem of environmental pollution is the focus of current social attention. The phenomena of straw burning and old firewood stove use in rural areas exist, and a large amount of dust and greenhouse gas are discharged. At present, biomass energy waste is mainly crop waste, and a large part of the biomass energy waste can be used as energy. In addition, the vast majority of forestry and wood processing waste can also be used as energy.
The biomass fuel gas produced by the biomass gasification furnace belongs to green new energy. The raw materials generated by the biomass gas are crop straws, forest waste, edible fungus residues, cattle, sheep and livestock manure and all combustible substances, so the biomass gas is an inexhaustible renewable resource. The biomass gas can solve the problem of energy consumption (cooking, heating and shower) of all natural life, and can be burnt like liquefied gas, thereby completely changing the life style of sooting and burning in rural areas of China, replacing the traditional firewood stove with liquefied gas. In addition, the biomass gas has wider application prospect in the industrial aspect, not only can be directly used as industrial gas, but also can be supplied to power generation equipment for power generation.
The ash tray mechanism is a main body part of the biomass gasification furnace, ash slag generated after biomass fuel put into the furnace body is incompletely combusted is discharged from the ash tray mechanism, and air also enters the furnace body through the ash tray mechanism. In actual use, the ash tray mechanism in the prior art often has massive ash to fall into an ash discharging hopper, so that the ash breaking effect is poor, and the ash discharging operation is inconvenient. And the air supply is not uniform, so that the gasification effect of the biomass fuel is influenced.
Disclosure of Invention
To exist not enough among the prior art, the utility model provides an ash tray mechanism for bio-gasification furnace solves current ash tray broken slag and arranges grey effect poor, the inhomogeneous problem that influences biomass fuel's gasification effect of air supply. The utility model adopts the technical proposal that:
an ash tray mechanism for a biological gasification furnace is positioned at the bottom of an updraft type gasification furnace and used for discharging ash and guiding air; comprises an ash tray shell, a top cover and a connecting flange; the two ends of the ash tray shell are provided with openings; the top end of the ash tray shell is hermetically connected through the top cover, and the edge support at the bottom end is connected with the internal structure of the gasification furnace through the connecting flange; and a plurality of air outlets are uniformly distributed on the ash tray shell.
Further, the top cover is a circular end cover with the diameter of 250 mm.
Furthermore, a plurality of the air outlets are distributed on the surface of the cone layer by layer.
Further, the transverse holes of the air outlet holes are equally spaced from one another.
Furthermore, the gas outlet holes are arranged from bottom to top, the distance between the hole layer and the hole layer is increased layer by layer, and the number of the holes is gradually decreased.
Further, an included angle between the bottom of the ash tray shell and the connecting flange is 30-35 degrees.
The utility model has the advantages that:
1) air outlets are uniformly distributed in the ash tray shell of the ash tray mechanism for the biological gasification furnace, so that air entering from the air inlet at the bottom can uniformly enter the gasification furnace body, and the combustion efficiency is improved.
2) The ash on the ash tray of the ash tray mechanism for the biological gasification furnace can automatically drop, the problems of accumulation, blockage and the like of an ash bin can be avoided, and the service life is long.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 and 2, in an ash tray mechanism for a bio-gasification furnace according to an embodiment of the present invention, the ash tray mechanism for a biomass gasification furnace is located at the bottom of an updraft type gasification furnace, and is used for discharging ash and guiding air; comprises an ash tray shell 1, a top cover 2 and a connecting flange 3; the two ends of the ash tray shell 1 are provided with openings; the top end of the ash tray shell 1 is hermetically connected through the top cover 2, and the edge support at the bottom end is connected with the internal structure of the gasification furnace through the connecting flange 3; a plurality of air outlets 4 are uniformly distributed on the ash tray shell 1.
Specifically, the top cover 2 is a circular end cover with the diameter of 250mm, and production experiments prove that the top cover is the most appropriate size, too small is inconvenient to produce, and too large ash slag is easy to accumulate; a plurality of venthole 4 distributes at the circular cone surface successive layer, the interval between 4 horizontal holes of venthole and the hole equals, supreme is down followed to venthole 4, and the interval successive layer between poroid layer and the poroid layer increases, and the hole number is decrement gradually. The law can guarantee that air entering from the air inlet at the bottom uniformly enters the gasifier body, and the combustion efficiency is improved.
Specifically, ash tray casing 1 bottom with the contained angle between flange 3 is 30-35 degrees, can guarantee that the ash on the ash tray drops automatically, and this design ash tray casing 1 is level and smooth simultaneously, can not take place the ash storehouse and accumulate the card scheduling problem, long service life.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
