Abstract
The utility model relates to a fire grate of a biomass gasification furnace. The fire grate comprises an upper fire grate, a lower fire grate and a transmission motor, the upper fire grate is connected with the transmission motor, and the transmission motor drives the upper fire grate to reciprocate on the lower fire grate along the direction perpendicular to carbon discharge clearances of the lower fire grate so that carbon discharge clearances of the upper fire grate and the lower fire grate are staggered or overlapped. Besides, the upper fire grate and the lower fire grate are hollow steel pipe structures, and cooling water is led inside the hollow steel pipes. Ash is discharged alternatively by the clearances of the upper fire grate and the lower fire grate which are led in cooling water, thereby resolving the problem that raw materials which are not combusted completely are discharged from the conventional gasification furnace. Further, the upper fire grate and the lower fire grate have fine ash discharge effect, high biomass utilization rate, simple structure, deformation resistance in environments with high temperature, long service life and high practicability.
Description
Technical field
The utility model relates to a kind of fire grate, is a kind of fire grate that biomass gasifying furnace uses that is used for specifically.
Background technology
Biomass such as tradition crop stalk often adopt burning disposal, have a strong impact on the air ambient and the fire safety of rural area and surrounding cities.The most direct treatment process of existing biomass is the biomass material gasification to be generated inflammable gas replace traditional Sweet natural gas, be used for urban residents' cooking, hot water, heating etc., at present domestic method with biomass material gasification generation combustible gas is: adopt vapourizing furnace under the anaerobic situation burning of vaporizer endogenous substance to be produced combustible gas, can disposablely feed in raw material, continuous burning uses, straw is when the vapourizing furnace internal combustion, the straw of fire grate top is not that disposable perfect combustion is fallen, it is to burn gradually from the bottom to top, the dust stratification of bottom must in time be discharged, and therefore traditional individual layer fire grate can not satisfy the use of vapourizing furnace well.As the patent No. is 200820025777.3 disclosed biomass gasifying furnace fire grates, adopt individual layer water-cooled grate structure, by fire grate longitudinal tubule (L tubule) gap ash discharge, though water-cooled row can guarantee that it is indeformable under straw incendiary high temperature in vaporizer, when normal gasification, and combustion, the imperfect combustion straw on dust stratification upper strata is easily discharged by the longitudinal tubule (L tubule) gap, fire grate ash discharge weak effect, serious waste straw resource, and influence vapourizing furnace combustion by-product purity and gas yield, practicality is low.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model provides a kind of simple in structure, and the fire grate ash discharge is effective, and work-ing life is normal, can make full use of the biomass gasifying furnace fire grate of straw resource.
The technical solution adopted in the utility model is: a kind of biomass gasifying furnace fire grate, its technical characterstic is that described fire grate comprises upper and lower fire grate and driving motor, upper fire-grating connects driving motor, and driving motor transmission upper fire-grating goes out the to-and-fro movement of carbon gap direction in the lower fire grating upper edge perpendicular to lower fire grating makes the upper and lower fire grate carbon gap that goes out separately be staggered or overlap condition.On the fire grate biomass combustion fully after, driving motor drives upper fire-grating makes the carbon gap that of upper and lower fire grate be staggered or overlap condition along go out the to-and-fro movement of carbon gap direction perpendicular to lower fire grating, when the upper and lower gap of upper and lower fire grate was staggered state, the carbon on the upper fire-grating can't relief outlet; When the upper and lower gap of upper and lower fire grate in an overlapping during state, the carbon on the upper fire-grating is discharged by the upper and lower gap of upper and lower fire grate, dust stratification in time can be discharged, and prevents that imperfect combustion straw from discharging, and the fire grate ash discharge is effective, straw utilization ratio height.
Further, described upper and lower fire grate adopts the hollow steel pipe structure, the inner logical water quench of hollow steel pipe.Upper and lower fire grate adopts water coolant to cool off in real time, under the high-temperature work environment, can effectively reduce upper and lower fire grate temperature in vapourizing furnace, protects upper and lower fire grate indeformable, increases the service life.
Ash discharge hockets in the upper and lower fire grate of the utility model employing water flowing refrigerative gap, solved the problem that is discharged from when raw material is imperfect combustion in traditional vapourizing furnace, upper and lower fire grate ash discharge is effective, biomass utilization ratio height, it is simple in structure, indeformable under the fire grate hot environment, long service life, practical.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: upper fire-grating 1, last gap 11, lower fire grating 2, following gap 21, driving motor 3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 1, the biomass gasifying furnace fire grate mainly comprises upper fire-grating 1, lower fire grating 2 and driving motor 3.Upper fire-grating 1 and lower fire grating 2 adopt the hollow steel pipe structure, logical water quench in the hollow steel pipe, upper fire-grating 1 connects driving motor 3, the last gap 11 of upper fire-grating 1 and the following gap of lower fire grating 2 21 corresponding settings, driving motor 3 transmission upper fire-gratings 1 make the upper and lower gap of upper and lower fire grate be staggered closed sealing in lower fire grating 2 upper edges perpendicular to following gap 21 direction to-and-fro movements or overlapping opening goes out the carbon state.
Claims (2)
1. biomass gasifying furnace fire grate, it is characterized in that: described fire grate comprises upper and lower fire grate (1,2) and driving motor (3), upper fire-grating connects driving motor, driving motor transmission upper fire-grating goes out carbon gap (21) direction to-and-fro movement in the lower fire grating upper edge perpendicular to lower fire grating makes the upper and lower fire grate carbon gap (11,21) that goes out separately be staggered or overlap condition.
2. biomass gasifying furnace fire grate according to claim 1 is characterized in that: described upper and lower fire grate (1,2) adopts the hollow steel pipe structure, the inner logical water coolant of hollow steel pipe.
