Description

The following spray integration biomass gasification stove

Technical field

The utility model relates to a kind of biomass gasifying furnace, refers in particular to a kind of following spray integration biomass gasification stove.

Background technology

China is a large agricultural country, and biomass resource is very abundant.According to statistics, the annual crop stalk that produces of China is about 700,000,000 tons, and traditional treatment process (cooking with, open-airly burn, the open-air accumulation) not only cause the poor efficiency utilization of biomass resource, also seriously polluted environment simultaneously.For those economy fall behind relatively, more scattered rural subscribers on the geographical position, the realization central gas supply is more unrealistic.Therefore, development cost is lower, and the household biomass gasifier that efficient is higher, suitability is stronger has very strong economic implications, is subjected to peasant's favor deeply, and application prospect is very wide.But up to the present, still be in the initial stage that research is used in the household biomass gasifier design, many technical matters await further solution.The following defective of existing household biomass gasifier ubiquity: tar is handled unclean, aerogenesis does not continue, must open feeding cover during stirring, vapourizing furnace produces very big flue gas when work, take off lid and must cause flue gas to leak this moment, and the loss of existing energy has operational trouble again, cause cooking to be interrupted, even influence kitchen's physical and mental health.Therefore, a lot of vapourizing furnaces all are in does not work or half working order, does not exist the stove kind of above-mentioned defective to have the problem of cost of manufacture than high several times of conventional oven again individually, so in this field bigger room for improvement is arranged still.

It is simpler to have occurred a kind of structure now again, cost is not high again, operate easier producer, just have simple in structure as Chinese patent ZL02277000.3 " producer ", ZL02277525.0 " shaking blanking producer ", ZL01244199.6 " family expenses stalk gasifier ", cost is lower, use more convenient, characteristics such as energy-saving effect is better, but this vapourizing furnace still exists: the material consumption is higher, gas production rate is on the low side, the fuel gases calorific value that produces not high, flame is red partially, energy-saving effect is not really desirable; Vapourizing furnace is longer each start time; Lime-ash mostly is the charcoal of not grilling thoroughly, and utilising efficiency is lower; The user is after buying this producer, must after contriver's strict training, can normally use in advance, the existence of these shortcomings, will influence the penetration and promotion of this energy-efficient equipment to a certain extent, most of in addition domestic biomass gasification stove all needs to be connected with cooking stove by pipeline, and the connecting tube of this split type vapourizing furnace is easy to be stopped up by tar.

Summary of the invention

For fear of with overcome above-mentioned deficiency, the purpose of this utility model provides a kind of reinforced son of uncapping that need not, start time is short, the material gasification fully, the following spray integration biomass gasification stove of no tar blocking pipe.

The realization the technical solution of the utility model is:

The following spray integration biomass gasification stove mainly comprises: exhaust smoke valve, cooking stove, steam supply valve, the air feed valve, feeding cover, the hopper of band screw feeder, body of heater, nozzle, ash discharging hole, blower fan, sewage draining exit, buffering gas holder, speed control switch, it is characterized in that: the Lower Half of body of heater is a vertebra shape structure, has a nozzle that links to each other with blower fan, nozzle to be provided with an eye of wind that sprays downwards in the body of heater bottom; The top of body of heater is a feeding cover, and top right-hand side is the hopper of a band screw feeder, and upper left limit is a cooking stove; Cooking stove bottom is the buffering gas holder, and cushion gas cashier's office in a shop portion is equipped with exhaust smoke valve, and bottom establishes sewage draining exit, and the buffering gas holder directly links to each other both top intercommunications with the vapourizing furnace body of heater; Steam supply valve, air feed valve, speed control switch are fixed on cushion gas cashier's office in a shop, and the rotating speed of blower fan is controlled by speed control switch, and the firepower size of cooking stove is controlled by steam supply valve, and the combustion air that the while cooking stove needs is regulated by the air feed valve.

The utility model has the advantages that:

(1) have only a point of ignition, local temperature is raise rapidly, reach gasification temperature, greatly reduce start time;

(2) nozzle sprays downwards, the charcoal burning of furnace bottom can be exhausted, and improves prepared using efficient greatly;

(3) be provided with the hopper of a band screw feeder, use so at ordinary times that can to beat feeding cover reinforced, solved the problem of wanting blowing out and furnace gas leakage when reinforced;

(4) integrated design does not need to install after the user buys and can directly use, and has avoided the problem of split type vapourizing furnace pipe leakage tar simultaneously.
