Abstract

The utility model discloses a lateral feeding type combustor of biomass gas... A gas inlet pipe (3) is installed on the outer wall of a shell (1) and is communicated with an inner chamber of the shell (1); an inner container (2) is arranged in the inner chamber of the shell (1); gas inlets (6) of which the number is larger than or equal to one are machined on the inner container (2); an air input pipe (4) stretches into the inside part of the shell (1) from the center of the bottom of the shell (1); a plurality of air injecting holes are formed on the air input pipe (4); a plurality of chassis pores (5) which are communicated with the inner chamber of the inner container (2) are machined on the bottom surface of the shell (1); and an opening shell (7) or a shrinking shell (7a) is fixedly connected with the top end of the shell. According to the lateral feeding type combustor, as oxygen in pure gas is increased, the combustion temperature of the gas is improved; the gas use time is shortened; the gas consumption is saved; and the lateral feeding type combustor can be used as a gas use tool for industrial heating or material drying and has practicability and popularization value.

Description

Biological fuel gas side-feeding type combustor

Technical field

The utility model relates to a kind of same biomass gasifying furnace (gas furnace) and matches and advance the formula combustor at the bottom of the biological fuel gas that uses.

Background technology

For clean biological fuel gas is provided to people, the research of biomass gasification technology has at present caused that each side payes attention to, and also has many reports; Though its gasification process and practical gap are also very big; But start to walk after all, the focus of concern draws attention, and the upsurge of exploitation is not flame-out; Also have few report but how the combustion gas of being produced by gasification furnace (or gas furnace) is carried out good burning, it is the link of biomass gasification technology after all, also is that biomass gasification technology is improved a great problem in the process.Traditional general cooking stove that adopts the infrared ceramic plate to process of biomass gasification burning burning, there is secondary oxygen supply distribution inconvenience in this equipment (or method), ignition temperature is lower and the aperture of ceramic wafer is prone to problems such as blocked.

Summary of the invention

The purpose of the utility model is to provide a kind of side-feeding type combustor that can gasify to the living beings of biomass gasification burning active combustion, raising ignition temperature, enhancing living beings harmless treatment effect.

For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: described a kind of biological fuel gas side-feeding type combustor comprises that shell, inner bag, combustion gas go into pipe, air input pipe and open enclosure or shrink shell; The inner chamber that pipe stretches into shell is gone in combustion gas in that side wall of outer shell is installed; The inner chamber of shell is furnished with inner bag, has quantity on the wall of inner bag more than or equal to 1 fuel gas inlet, and a bottom centre position from shell of air input pipe stretches into the inner chamber of shell inner bag; The quantity of on the bottom surface of shell, processing is communicated with the inner chamber of inner bag more than or equal to 1 chassis osculum, is fixed with open enclosure on the top of shell or shrinks shell.

Adopt a kind of biological fuel gas side-feeding type combustor that as above technical scheme provides compared with prior art, technique effect is:

1. the inner chamber at shell is provided with inner bag; On inner bag, be processed with a plurality of fuel gas inlets; Clean combustion gas can increase the oxygen composition in the combustion gas around these fuel gas inlets arrival air input pipe tops, improve the fuel gas buring temperature; Can shorten the usefulness gas time and save gas consumption, the convenience of daily gas is provided for people.

2. cancelled traditional infrared ceramic plate kitchen range, reduced the obstruction of tar and ash content, prolonged the service life of gas burner system, reduced the cost of gasification furnace ceramic panel.

3. applied range can be used as industrial combustion or gas combustion apparatus is used in oven dry.

Description of drawings

Fig. 1 is the described a kind of cross-sectional schematic that the biological fuel gas side-feeding type combustor of open enclosure is arranged of the utility model, also is the Figure of abstract of the utility model.

Fig. 2 is the cross-sectional schematic that the biological fuel gas side-feeding type combustor that shrinks shell is arranged.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to describe in detail.

Shown in accompanying drawing; Described a kind of biological fuel gas side-feeding type combustor is the combustion gas side-feeding type combustor of open enclosure to be arranged or the combustion gas side-feeding type combustor that shrinks shell is arranged, and comprises that shell 1, inner bag 2, combustion gas go into pipe 3, air input pipe 4 and open enclosure 7 or shrink shell 7a.Be equipped with combustion gas at the sidewall of (cylindrical) shell 1 and go into pipe 3, the inner chamber that pipe 3 stretches into shell 1 is gone in combustion gas, goes into the inner chamber of the clean combustion gas of pipe 3 inputs to shell 1 from combustion gas.Inner chamber at shell 1 is fitted with (cylindrical) inner bag 2, around inner bag 2, has quantity on the wall more than or equal to 1 fuel gas inlet 6, goes into combustion gas that pipe 3 comes in is got into inner bags 2 by each combustion inlet 6 inner chamber from combustion gas.Air input pipe 4 stretches into the inside of shell 1 from the bottom centre position of shell 1; The individual chassis of the N that on the bottom surface of shell 1, has (integer of N >=1) osculum 5 is communicated with the inner chamber of inner bags 2, can get into the inner combustion gas of inner bag 2 in open enclosure 7 or shrink required oxygen is provided when burn in shell 7a place from trend.The head of air input pipe 4 be processed with quantity more than or equal to 1 and can be evenly or the venthole of non-uniform Distribution, this is a known technology.Improve the oxygen content the biological fuel gas from the air of each venthole ejection of air input pipe 4 heads with the combustion gas mixing that gets into each combustion inlet 6 on the inner bag 2, improve the ignition temperature of biological fuel gas.Be fixed with open enclosure 7 on the top of shell 1 or shrink shell 7a.(like Fig. 1) suitably amplified the gas outlet of combustor, be mainly used in the bigger operating modes of heating surface (area) (HS such as boiler heat energy supply, (like Fig. 2) suitably shrinks the gas outlet of combustor, mainly in the oven dry occasion.

During use; Pipe 3 is gone in combustion gas link to each other, in air input pipe 4, send air, behind gasification furnace (gas furnace) normal gas producing, open the hand-operated valve (or switch) on the fuel gas of gasifying furnace efferent duct with (miniature) blower fan with the clean combustion gas efferent duct of gasification furnace (gas furnace); Close the air discharge cook on the gasification furnace; Make clean combustion gas go into pipe 3 from combustion gas and arrive open enclosure 7 together with the air from air input pipe 4 or shrink the periphery of shell 7a through fuel gas inlet 6, igniting can reach the purpose of heating or oven dry.
