Abstract

The utility model relates to a furnace of straw gas producer, in order to solve the problem that the lower part of straw collapses in the combustion process in the gas producer, the upper part is bridged and burnt, the utility model is characterized in that the furnace comprises an inner cylinder and an outer cylinder, the upper half part in the inner cylinder is provided with a replaceable fire-resistant lining, the lower half part is provided with an inverted frustum-shaped cast iron furnace, the upper end of the annular space between the inner cylinder and the outer cylinder is provided with an upper sealing plate, the lower end is provided with a spoiler and a guide plate, an air inlet pipe enters the replaceable heat-insulating lining from the outer cylinder, a fire-resistant heat-insulating material is arranged between the cast iron furnace. The utility model can realize high furnace temperature, less consumption, high gas production quality and reduced labor intensity in the gas production process.

Description

A kind of burner hearth of straw producer gas generator

The utility model relates to a kind of burner hearth of straw producer gas generator.

Existing straw producer gas generator is in the straw combustion processes, because the suction of negative pressure, in burner hearth, be easy to form to put up a bridge, burn and form the cavity, directly influence the quality of institute's producing coal gas, this mainly is because existing straw producer gas generator all adopts the vertical barrel type burner hearth, thus straw in combustion processes because ash content whereabouts and negative pressure-pumping very easily cause the top that subsides, bottom to put up a bridge, the result is that furnace temperature is low, the aerogenesis poor quality consumes high.

The purpose of this utility model is to propose a kind of solution straw in the producer gas generator combustion process, the technical scheme that prevents the bottom to subside top puts up a bridge and to burn, to realize the furnace temperature height, consume few, aerogenesis quality height.

The purpose of this utility model is achieved in that a kind of burner hearth of straw producer gas generator, burner hearth comprises inner barrel and outer cylinder body, removable refractory liner is arranged in the inner barrel first half, there is the lug in 6 strap bolt holes at the middle part of inner barrel inwall, the platform of falling the garden shape cast iron burner hearth of flanged bolt hole is sitting on 6 lugs of inner barrel, and there is bolt that the cast iron burner hearth is fixed on the lug, annular space between cast iron burner hearth and inner barrel is filled flame-proof thermal insulation material, and use the following shrouding that welds together with inner barrel that flame-proof thermal insulation material is sealed, constitute an annular space between inner barrel and outer cylinder body, the upper end of annular space is sealed with upper sealing plate, gas outlet tube is arranged at the top at outer cylinder body, there is half garden annular spoiler lower end at the annular space of gas outlet tube one side, promptly on half garden annular plate, have 3 through holes at least, in the annular space lower end, half garden of gas outlet tube opposite side by at least 4 flow deflectors are housed, from the outer cylinder body Lower Half to the removable refractory liner in inner barrel top in along at least 4 blast pipes of garden Zhou Junbu.

The utility model has the advantages that: gasification rapidly, aerogenesis is fast, light a fire and to produce coal gas within back one minute, the phenomenon that can avoid straw in combustion processes, to put up a bridge and bore a hole, owing to adopted the burner hearth of the platform of falling garden shape, making the straw lime-ash is to carry out in order in the process that falls, rather than the cindery bottom of straw subsides suddenly in the vertical barrel type burner hearth, putting up a bridge in top, and causes the burning perforation, thereby guaranteed the generation coal gas that straw gasification stove can be continual and steady, not only alleviated labor intensity of operating personnel, and make it the gas production process and realized the furnace temperature height, consume few, aerogenesis quality height.

Fig. 1 is the chamber structure synoptic diagram of straw producer gas generator.

Fig. 2 is that the A-A of Fig. 1 is to sectional view.

Below in conjunction with accompanying drawing the utility model is described further.

A kind of burner hearth of straw producer gas generator in the accompanying drawing, it comprises inner barrel 1 and outer cylinder body 3, removable refractory liner 10 is arranged in inner barrel 1 first half, there is the lug 12 in 6 strap bolt holes at the middle part of inner barrel 1 inwall, the platform of falling the garden shape cast iron burner hearth 11 of flanged bolt hole is sitting on 6 lugs 12 of inner barrel 1, and cast iron burner hearth 11 is fixed on the lug 12 with bolt, annular space 1 of cast iron burner hearth 11 and inner barrel is filled flame-proof thermal insulation material 4, and use the following shrouding 7 that welds together with inner barrel 1 that flame-proof thermal insulation material 4 is sealed, 3 of inner barrel 1 and outer cylinder bodies constitute an annular space, the upper end of annular space is sealed with upper sealing plate 9, on the top of outer cylinder body 3 gas outlet tube 2 is arranged, there is half garden annular spoiler 6 lower end at the annular space of gas outlet tube 2 one sides, promptly on half garden annular plate, have 3 through holes, in the annular space lower end, half garden of gas outlet tube 2 opposite sides by 4 flow deflectors 8 are housed, from outer cylinder body 3 Lower Halves to inner barrel 1 top in the removable refractory liner 10 along 4 blast pipes 5 of garden Zhou Junbu, coal gas direction shown in arrow in the accompanying drawing 1 flows out to gas outlet tube 2.

A kind of burner hearth of straw producer gas generator, there is half garden annular spoiler 6 lower end at the annular space of gas outlet tube 2 one sides, it is uniform promptly to have 5 through holes on half garden annular plate, annular space lower end, half garden at gas outlet tube 2 opposite sides is uniform by 5 flow deflectors 8 are housed, from the Lower Half of outer cylinder body 3 to the top of inner barrel 1 in the removable refractory liner 10 along 6 blast pipes 5 of garden Zhou Junbu, other the same embodiment.
