Abstract
The utility model discloses a spraying-downwards type biomass gasification furnace, including a furnace body having an ash outlet on its bottom, the bottom of the furnace body is provided with a nozzle, the nozzle is provided with a wind-eye capable of injecting downwards; the nozzle is connected with an aeration pipe, the other end of the aeration pipe is connected with a fan outside the furnace body; a top end of the furnace body is provided with a feed lid, a side face of the furnace body is provided with a buffering wind chest, the upper of the furnace body is communicated with the buffering wind chest, the top end of the buffering wind chest is provided with a kitchen range, and an air-supply valve and a wind-supply valve are arranged between the kitchen range and the buffering wind chest. By means of mounting the nozzle on the bottom of the furnace body, it is capable of combusting the vegetable charcoal of the furnace bottom completely, such that a raw material usage efficiency is improved, and a startup speed is rapid; the furnace of the utility model has a simple structure, avoids a problem of pipe coke tar leakage, a convenient operation and improves a heat utilization efficiency.
Description
Technical field
The utility model relates to a kind of stove and accessory, especially a kind of following spray biomass gasifying furnace.
Background technology
At present, the annual agricultural crop straw 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 polluted environment simultaneously.And for those economy fall behind relatively, more scattered rural subscribers on the geographical position, also be difficult to realize central gas supply.Therefore, household biomass gasifier has very strong economic implications, and application prospect is very wide.The following defective of existing household biomass gasifier ubiquity: tar is handled unclean, the aerogenesis persistence is poor, 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, both caused the loss of energy, gives in the operation again and brought trouble, cause cooking to be interrupted, even influence the healthy of kitchen.Though now have some stove and accessorys to solve smoke problem, their complex structure, production cost height; Though also have some stove and accessorys simple in structure, but material consumption height, the combustion gas that produces is few, and fuel gases calorific value is not high, and flame is red partially, and its energy-saving effect is unsatisfactory, and vapourizing furnace is longer each start time, lime-ash mostly is the charcoal of not grilling thoroughly, and is lower to the utilising efficiency of raw material, and very bothers in operation; 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.
The utility model content:
The purpose of this utility model is: a kind of following spray biomass gasifying furnace is provided, and it simple in structure, start time is short, can continue aerogenesis, gas producing efficiency and heat utilization efficiency height, and avoided the tar problem of the connecting tube of vapourizing furnace, to overcome the deficiencies in the prior art.
The utility model is achieved in that the following spray biomass gasifying furnace, comprises that the bottom is provided with the body of heater of ash output hole, is provided with a nozzle at bottom of furnace body, is provided with the eye of wind that can spray on nozzle downwards; Be connected with a ventpipe on nozzle, the other end of ventpipe is connected with body of heater blower fan outward; Top at body of heater is provided with feeding cover, is provided with the buffering gas holder in the side of body of heater, and the top of body of heater is communicated with the buffering gas holder, is provided with cooking stove on the top of buffering gas holder, is provided with steam supply valve and air feed valve between cooking stove and buffering gas holder.
On cooking stove, be connected with exhaust smoke valve, and on exhaust smoke valve, be provided with the combustible gas probe.
On blower fan, be connected with speed control switch.
Bottom at the buffering gas holder is provided with sewage draining exit.
Owing to adopted technique scheme, compared with prior art, the utility model has been installed one in the bottom of body of heater can jet downwards nozzle, the charcoal burning of furnace bottom can be exhausted, and improves prepared using efficient greatly, increased gas production rate, lasting aerogenesis that can be stable, and, therefore local temperature is got a promotion rapidly because point of ignition has only one, shorten the gasification time, accelerated toggle speed; And adopt all-in-one-piece syndeton between body of heater of the present utility model, buffering gas holder and the cooking stove, do not needed the user to install voluntarily, not only simple in structure, and avoided the problem of pipe leakage tar, and easy to operate, also improved efficiency of utilization.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structure of following spray biomass gasifying furnace as shown in Figure 1, produce the body of heater 1 that a bottom has ash output hole 14, and nozzle 2 of ventpipe 3 accesses of making by a refractory materials is installed in body of heater 1 bottom, produce the eye of wind that can spray on nozzle 2 downwards, the blower fan 4 that the other end of ventpipe 3 is outer with being placed on body of heater 1 is connected; A feeding cover 5 is installed on top at body of heater 1, lateral location at body of heater 1 is installed a buffering gas holder 6, a sewage draining exit 13 is offered in bottom at buffering gas holder 6, and the top of body of heater 1 is communicated with buffering gas holder 6, a cooking stove 7 is placed on top at buffering gas holder 6, cooking stove 7 is connected with buffering gas holder 6 by steam supply valve 8 and air feed valve 9, and on cooking stove 7, an exhaust smoke valve 10 is installed, on exhaust smoke valve 10, connect combustible gas probe 11; On blower fan 4, connect speed control switch 12; Steam supply valve 8, air feed valve 9 and speed control switch 12 all are fixed on the buffering gas holder 6, use with convenient.
In use, close steam supply valve 8 earlier, open exhaust smoke valve 10, open the feeding cover 5 at body of heater 1 top, put in the body of heater 1 after a spot of inflammable substance are lighted; In order to guarantee gasification result, the fire in a stove before fuel is added in the body of heater 1 must be abundant, for the fire in a stove before fuel is added is fully burnt, it is combustion-supporting to open blower fan 4 earlier, after the fire in a stove before fuel is added is lighted, close blower fan 4 earlier, again previously prepd fuel is put into body of heater 1, after fuel is installed, cover feeding cover 5, and open blower fan 4, have a large amount of flue gases in the exit of exhaust smoke valve 10 and discharge, excessively after 2～3 minutes, can open steam supply valve 8 lights a fire, after cooking stove 7 is lighted, the exhaust smoke valve 10 of vapourizing furnace is closed,, just illustrate that fuel gasification is also incomplete if 7 on cooking stove does not fire, need close steam supply valve 8, again through suitably lighting after the smoke evacuation; Flame size is controlled by steam supply valve 8, and the combustion air that while cooking stove 7 needs is regulated by air feed valve 9, and the lime-ash that is produced in the body of heater 1 is discharged by ash discharging hole 14, and the waste water in the buffering gas holder 6 are by sewage draining exit 13 discharges; Speed control switch 12 can be controlled the rotating speed of blower fan 4.
