Abstract

The utility model relates to a novel environmental protection composite gasification furnace, which mainly consists of a combustion furnace and a furnace body. A hearth is arranged in the furnace body; a miniature blower is arranged at the lower part of the furnace body; an automatic ignition opening is formed on the site of the blower; a seal cover is arranged on an upper opening of the furnace body; a material pressing rod is arranged on the seal cover; the combustion furnace is connected with the furnace body through a gas pipe; one end of the gas pipe extends to the upper part of the furnace body; the other end thereof extends above a mixed combustor and is connected with a gas spray nozzle; and a plurality of air inlet holes in vertical staggering arrangement are formed on the wall of the combustor, and communicated with the atmosphere. The gas spray nozzle is downwardly connected in the central position of the upper opening of the combustor for spray combustion, and air steam impacts the bottom of the cavity of the combustor and air inlet holes on the wall of the combustor, and then immediately rebound, so that the flame spreads the whole combustor. Through reasonable secondary and a plurality of circular air distributions, the flame is stronger, and tar vapor in the gas is completely burned in the high temperature flame. The utility model has the advantages of simple structure, easy use and no pollution to the environment.

Description

Novel environment friendly combined gasification cooking stove

One, technical field

The utility model relates to a kind of gasification furnace and kitchen range, relates in particular to a kind of kitchen range that the tar water vapour thoroughly can be burnt.

Two, background technology

Have a variety of in the current biomass gasifying furnace manufacturing, its result of use but has the branch of good job, gasification furnace ubiquitous problem in combustion process is: heat-insulating property is poor, burning time is short, it is insufficient to burn, the aerogenesis instability, calorific value is not enough, and too high to demanded fuel, aniseed or wet feed do not produce gas at all, in addition, tar water vapour problem generally is not resolved, though a lot of producer has taked multiple measure, as by water filtration, corncob, pine needle and industrial chemicals filter, but still contain the tar water vapour in the combustion gas, blocking pipe and kitchen range make it can not normal operation.Existing in addition burner of gasification furnace, generally by natural gas and the repacking of liquefied gas kitchen range, this type of kitchen range space is less, and kitchen range intake deficiency also causes combustible gas fully not burn, and after use a period of time, the tar water vapour is piled up, the adversely affecting its combustion performance.

Three, summary of the invention

The purpose of this utility model is to overcome above shortcoming, and a kind of novel environment friendly composite gasification furnace and kitchen range are provided, and the technical problem that it will solve is: heat-insulating property is poor, short unstable reaching of aerogenesis time requires too high problem to combustion material.

Another technical problem that will solve is, it is serious to accompany tar water vapour phenomenon in the gasification furnace combustion process, blocking pipe and kitchen range, problem that can not normal operation.

The technical scheme that first problem of the utility model adopts: it is characterised in that and comprises that being provided with burner hearth, body of heater bottom in cement body of heater, the body of heater is provided with small blower, lighting-up tuyere and ash hole automatically, body of heater mouth place is provided with seal cover, seal cover is provided with compressing rod, the body of heater bottom is provided with blast pipe, upper of furnace body is provided with appendix, connect by the secondary aid distributing pipe between blast pipe and the appendix, for regulating the size of air quantity, the secondary aid distributing pipe is provided with by-pass cock.

The advantage of first technical scheme of the utility model is: because body of heater adopts cement to manufacture, the heat transfer property of iron sheet is low relatively, good heat insulating, owing to improve heat-insulating property, its existing gasification furnace aerogenesis is stable, sufficient combustion, gas production is big, and the aerogenesis time is long, and can be applicable to various different fuels, the also available aniseed of both available particle, the combustible of also available wet feed of both available siccative and various wet conditions.

The technical scheme that second problem that will solve of the utility model will adopt is: the utility model includes stove, appendix, appendix one end stretches to upper of furnace body, the other end is slightly downward-sloping to stretch to that the kitchen range mixing burner is suitable for reading to be connected with gas nozzle, it is characterized in that comprising gas nozzle and mixing burner, the burner wall circumference is placed down several air admission holes of staggered branch, vertically downward with the gas spray combustion, mixing burner top is provided with movable infrared irdome to gas nozzle in mixing burner center suitable for reading.

The advantage of second technical scheme of the utility model is: the change of traditional structure mode, be that gas nozzle is at the downward spray combustion of the upper vertical of mixing burner, changed airflow direction first, flame by the gas nozzle ejection, carry out the secondary mixing combination burning in conjunction with the combustion air bump mixing burner wall of bringing into synchronously from air admission hole, airflow strikes at the bottom of mixed combustion wall and the chamber after moment rebound, fill the air whole burner, produced intense flame.

Because diameter that burner is suitable and height make burner have enough spaces and needed enough air to finish mixed combustion.

Without any need for measure and filter, also need not sewage disposal facility, directly burning is simplified literary writing by leaving out superfluous words, and joint has been given birth to expense, utilizes simple method to play good effect.

Mixed combustion wall circumference encloses fresh air inlet and directly communicates in ambient atmosphere, and required enough air of mixed combustion are provided.

Utilize the principle of jet combustion supporting, the organically fused weave in of flame on the flame of its injection and the combustor air inlet hole, make flame more fierce, calorific value is higher, the tar water vapour generation physical reactions that the air-flow that while is sprayed by air nozzle in the flame of high-temp combustion accompanies becomes fuel gas, thoroughly burns, improve efficiency of combustion, also avoided secondary pollution.

Be located at the movable infrared irdome on burner top,, make calorific value higher, widened function by the infrared heat radiation.

,, tar water vapour problem restricts the difficult problem that this technology can not enter the use field because of can not thoroughly solving because thereby the change of combustion system on traditional mechanism thoroughly broken through for a long time.
