Abstract

The utility model relates to a cooking stove, particularly a novel environment-friendly stalk gasification furnace. The novel environment-friendly stalk gasification furnace comprises a combustion furnace, a filter, a furnace body and a connecting pipe. A feed port is formed at the upper part of the combustion furnace. A seal cover is arranged on the feed port. A fuel-pressing rod is inserted on the seal cover. One end of the fuel-pressing rod is positioned at the upper part of a furnace cover. The top end of the fuel-pressing rod serves as the handle and the bottom end thereof is used for pressing the fuel. When the fuel is loosened during the combustion inside the furnace, the fuel-pressing rod is pressed downwards to compact the fuel, thereby ensuring the continuous combustion of the fuel inside the furnace. The stalk gasification furnace has the advantages of simple structure, reasonable design, reduced labor and time consumption, environment friendliness and low energy consumption; and is suitable for farmers.

Description

A kind of environment-protective stalk gasification furnace

Affiliated technical field

The utility model relates to a kind of kitchen range, relates in particular to a kind of environment-protective stalk gasification furnace.

Background technology

The main fuel of materials such as stalk, coal, faggot as cooking stove generally used in the rural area, is used for warming oneself cooking, and the direct burning of these materials can produce a large amount of flue gases, and it is very dirty, waste time and energy, not only polluted environment, and long-term the use also can be brought injury to human body.At present, some stalk gasifiers are also arranged on the market, but also there are some problems in these gasification furnaces, the one, fuel is put into stove after a period of time (general 1-3 hour), because the combustion volume of fuel diminishes, form the cavity in the gasification furnace, at this moment, be difficult to produce again fuel gas, use as continuing, necessary blowing-out machine is opened feeding cover, the air-supply of reinforced back, just can burn away, but open bell, cause air pollution, also influence the continuous use of gasification furnace, brought artificial trouble; What also have some gasification furnaces employings is wet filter, the winter cold in the north is owing to the aqueous vapor in the stalk is condensed at low temperatures, be difficult to burned utilization, the impurity such as tar that contain band in the fuel also can result in blockage, and the gas that discharges in burn tar, the impurity process has also caused severe contamination to environment.

Summary of the invention

The purpose of this utility model is to provide for vast farmers a kind of a kind of novel straw gasification furnace of simple in structure, reasonable in design, time saving and energy saving, environmental protection and energy saving.

For achieving the above object, the technical solution adopted in the utility model is: a kind of environment-protective stalk gasification furnace, comprise combustion furnace, filter, stove, tube connector etc., the top of combustion furnace is provided with charging aperture, on mouthful capping is arranged, be inserted with compressing rod in the capping, compressing rod one end is on bell top, the top is a handle end, the bottom is the binder end, the binder end can be annular, when fuel when the stove internal combustion produces the cavity, press downwards with compressing rod, again compacting fuel, the sustained combustion that keeps fuel in the stove, be provided with ash hole and air inlet in the stove bottom, body of heater is connected by escape pipe with filter, and escape pipe one end stretches to upper of furnace body, and the other end stretches to the filter bottom, and the termination has several apertures of giving vent to anger, filter bottom is provided with and feeds back pipe and communicate with combustion furnace, on the feedback pipe valve is arranged, when the condensate water in the filter and tar reach some, by feeding back the valve on the pipe, water and tar are fed back in the combustion furnace, the burning that acts as a fuel, filter top is provided with appendix, the tube wall of the appendix in filter is beaten N air admission hole, gas is transported to stove by the mouth of pipe and air admission hole, and stove and appendix are provided with switch valve, and stove top is provided with preheating ring, the bottom is a kitchen range, gas by after the preheating ring preheating, enters into following kitchen range earlier, takes fire.

The furnace body inside of described combustion furnace is provided with heat-insulation layer, generally to make with steel material. described appendix is provided with safety air vavle, when air pressure was excessive, safety effect was played in the decompression that opens the safety-valve. the fire-resistant metal material of the general employing of the material of combustion furnace, filter and pipeline.Described filter is a dry filter, can place the wire netting filter material in the filter, also can not put.

The beneficial effects of the utility model are: owing to adopted dry filter, the problem that winter owing to condensation of moisture cause filter bursting by freezing of wet filter in cold can not occur; Be provided with in filter and the burner and feed back pipe, the tar in the filter, water can be passed through the feedback pipe of filter bottom, feed back in the furnace chamber of burner, water and tar resolve into combustible gas under the high temperature of combustion furnace like this, increase the calorific value of Straw Gas, saved fuel, reduced environmental pollution.Kitchen range of the present utility model is owing to be provided with preheating ring, and during use, combustible gas further cracking of heating back in preheating ring earlier improves combustion efficiency, has also avoided kitchen range by the tar blockage problem, plays the effect of environmental protection and energy saving more.

Description of drawings

Figure below is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment

As seen from the figure, a kind of environment-protective stalk gasification furnace is mainly by combustion furnace 1, filter 12 and stove 17 constitute, wherein combustion furnace 1 inboard is provided with refractory insulating layer 4, combustion furnace 1 top is provided with charging aperture 21, on mouthful capping 3 is arranged, be inserted with compressing rod 2 in the capping 3, when stove 1 internal combustion of fuel produces the cavity, press downwards with compressing rod 2, again compacting fuel, the sustained combustion that keeps fuel in the stove, be provided with ash hole 5 and air inlet 7 in Fuel Furnace 1 bottom, public attention 6 on the air vents 7 is sent in the combustion furnace 1, combustion furnace 1 is connected by escape pipe 10 with filter 12, escape pipe 10 1 ends stretch to body of heater 1 top, an other end stretches to filter 12 bottoms, and the termination of escape pipe 10 has several ventholes 11, filter 12 bottoms are provided with and feed back pipe 8 and communicate with combustion furnace 1, feed back pipe 8 and be provided with feedback tube valve 9, when the condensate water of filter 12 and tar reach some, by feeding back the feedback tube valve 9 on the pipe 8, water and tar are fed back in the coal furnace 1, as combustion fuel, filter 13 tops are provided with appendix 13, are equipped with a lot of air admission holes 14 at the tube wall of the appendix 13 of filter 12, gas is transported to stove 17 by the mouth of pipe and the air admission hole 14 of appendix 13, stove 17 is provided with stove switch valve 16 with gas transmission 13 and controls the conveying of stalk combustible gas and close, and stove 17 tops are provided with preheating ring 18, and the bottom is a kitchen range 20, preheating ring 18 links to each other with kitchen range 20 by tube connector 19, gas by after preheating ring 18 preheatings, enters into following kitchen range 20 earlier, begins to burn.
