Abstract

The utility model discloses a household crop waste gasifier, which comprises a furnace body and a blowing pipe. The inside of the furnace body is provided with a furnace cavity, the lower part of thefurnace cavity is provided with an air collecting chamber, one end of the blowing pipe is connected with an air blower, the lower end of the furnace body is provided with an ash outlet, the inside ofthe furnace cavity is provided with an airflow diversion cover, the airflow diversion cover is communicated with the blowing pipe through a pipeline, the air collecting chamber is communicated with acook through an air outlet pipe, an empty cavity is formed between the furnace cavity and the inner wall of the furnace body, and the empty cavity is communicated with the blowing pipe. When the air flows into the empty cavity through the blowing pipe, the annular airflow is formed from top to bottom around the furnace cavity, and the smoke and air above the furnace can not overflow upwards, thereby reducing the air pollution. Simultaneously, the corrosive gas in the furnace can not get close to the inner wall of the furnace due to the heavy annular airflow, thereby prolonging the service lifeof the furnace.

Description

Family expenses wastes of crops gasification furnace

Technical field

The utility model relates to a kind of gasification furnace, particularly a kind of home-use small-sized wastes of crops gasification furnace.

Background technology

At present, the cook heating etc. of most of area, rural area is still adopted the original kitchen range top or stove mostly, is directly the plant fuel burning to be heated, and a large amount of cigarettes and dust all can be just given birth in burning at every turn, environment is caused very big pollution, and can influence the healthy of staff.In addition in the rural area some bio-fuels such as stalk, peanut shell, straw with usually go out of use need not, cause the waste of resource.People have invented gasification furnace for this reason, utilize living beings to pass through airtight anoxia, be used in a kind of fuel gas that produces after slide pyrolysismethod and the heat chemistry oxidizing process, this gas is a kind of air mixture, contain carbon monoxide, hydrogen, methane, etc., also claim biogas, heat, warm oneself through row by this air mixture.This gasification furnace has advantages such as smoke is few, environmental protection, has improved artificial working environment greatly.Existing gasification furnace generally is divided into two types: i.e. updraft type, downdraft.The updraft type gasification furnace should not be promoted because gas is discharged, polluted greatly from the stove top.The shortcoming of downdraft is: 1) feeding device can not satisfy the charging characteristics of gasification furnace; 2) the excessive gas of its stove top than updraft type better but have flue gas from stove discharge may so that cause indoor pollution; 3) be provided with steam generator in the stove, structures such as gas medium preheating chamber are too complicated, are unfavorable for operation, and furnace chamber has flame retardant coating, come off easily during use, need to repair again.Between above-mentioned shortcoming,, the downdraft stove still keeps personnel (old, a middle-aged person, educational level junior) operation so being unfavorable for the rural area.Therefore.Above two kinds of gasification furnaces very big resistance is arranged using to promote, even can't implement.

The utility model content

At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of gasification furnace of new structure, and the gasification furnace of this structure can prevent that cigarette, gas from upwards overflowing, thus avoid upwards overflowing the gaseous contamination environment.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of family expenses wastes of crops gasification furnace comprises a body of heater and a blower, forms a furnace chamber in the described body of heater, and the bottom of described furnace chamber is provided with a gas collection chamber, and an end of described blower is connected with air blast, and described body of heater lower end is provided with an ash hole; Being provided with the described airflow diversion cover of an airflow diversion cover in the described furnace chamber is communicated with described blower by pipeline, described gas collection chamber is communicated with kitchen range by escape pipe, form a cavity between described furnace chamber and the described inboard wall of furnace body, described cavity is communicated with described blower.

Based on above-mentioned major technique feature, lower furnace lever grate has metallic rod push-and-pull back and forth from ash hole, and stove fire is brushed lightly in the furnace bottom tank.

Based on above-mentioned major technique feature, its gas outlet is connected to the secondary air system, can increase discharge duct pressure at gas purification epistome or rear portion, strengthens gas combustion flame.

Technique scheme has following beneficial effect: because in technique scheme, form a cavity between furnace chamber and the inboard wall of furnace body, and this cavity and blower are connected, when this cavity passes through the blower air inlet, form annular airflow from top to bottom around the furnace chamber, such pressure reduction, when the stove top is lighted, cigarette, gas can't upwards overflow, thereby can reduce pollution to air, simultaneously bigger circulation makes the stove hollow heart foul smell body can't be near the stove inwall, thus the service life that also can improve stove.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Concrete enforcement side

As shown in Figure 1, as an embodiment of the present utility model, this family expenses wastes of crops gasification furnace comprises a body of heater 11 and a blower 21, forms a furnace chamber 12 in the body of heater 11, the bottom of furnace chamber 12 is provided with a gas collection chamber 13, and the body of heater lower end is provided with an ash hole 16.The top of furnace chamber 12 is provided with a pressing plate 17, and pressing plate 17 is connected with body of heater 21 by screw rod.Be provided with a lever grate 15 between described furnace chamber 12 and the gas collection chamber 13, ash hole 16 places are provided with a metallic rod and are connected with described lever grate 15.

One end of blower 21 is connected with air blast, be provided with a burning cover 22 in the furnace chamber 12, burning cover 22 is communicated with described blower 21 by pipeline, gas collection chamber 13 is communicated with kitchen range 33 by escape pipe 31, also be provided with a gas cleaning plant 32 on the escape pipe 31, form a cavity 18 between gas collection chamber 13 and described furnace chamber 12 and body of heater 11 inwalls, cavity 18 is communicated with blower 21.Escape pipe 31 passes through pipeline connection with blower 21, and pipeline is provided with switch 25, and this pipeline can be located at the front end or the rear end of gas cleaning plant.Also be provided with switch 23 and switch 24 on the blower 21, switch 25 and switch 26 lay respectively at the two ends up and down of cavity 18 air inlets 27.
