Hearth push-pull type ash discharging device for biomass gasifying furnace

Abstract

The invention discloses a hearth push-pull ash discharging device for a biomass gasifying furnace. The hearth push-pull ash discharging device is characterized in that an ash storing tank door is arranged on a sidewall of the lower end of a furnace body; a bottom fixing plate is fixedly connected to a transverse internal wall of an internal chamber at the lower end of the furnace body; a three-wall type ash storing box is manufactured on the bottom fixing plate; an ash storing box is positioned in an ash storing tank; the top end of one sidewall of the ash storing tank opposite to an ash storing tank door is close to a rear supporting plate; an ash falling plate guiding box is arranged on the sidewall of the furnace body; and an ash falling plate push-pull rod with a handle penetrates through an oil seal and then is connected to one end side of ash falling plates. A left supporting plate and a right supporting plate are fixedly connected to two longitudinal sidewalls of the furnace body; a front push-pull groove and a rear push-pull groove are fixedly connected to internal side edges of the left supporting plate and the right supporting plate; two end sides of the ash falling plates are positioned into the front push-pull groove and the rear push-pull groove; and the ash falling plates arranged in the front push-pull groove and the rear push-pull groove are positioned on the same level line as the ash falling plate push-pull rod. The push-pull ash discharging device is simple in structure and convenient to operate, and can effectively separate ash residue (dust) from a carbonized material or a semi-carbonized material, so that a continuous working capacity of the biomass gasifying furnace is improved.

Description

technical field [0001] The invention relates to an ash discharge device, in particular to a push-pull ash discharge device at the bottom of a biomass gasification furnace, which belongs to the C10J3 / 34 or C10J3 / 52 category. Background technique [0002] With the development of biomass gasification technology today, many scientific and technical personnel have paid more and more attention to both the process and the device. The biomass gasifier itself is becoming mature or has been actually applied; but the traditional biomass gasifier is used in practical applications. There are still many problems in the process. If these problems are not solved, it will affect the prospects of the biomass gasifier. For example, the "ashing" problem of the biomass gasifier is an example. Before the patent application of the present invention, such as ZL201120013927.0 "Double Helical Roller Ash Discharge Device for Gasifier", the ash discharge problem of biomass gasifier was discussed, and i...

Problems solved by technology

[0002] With the development of biomass gasification technology today, many scientific and technical personnel have paid more and more attention to both the process and the device. The biomass gasifier itself is becoming mature or has been actually applied; but the traditional biomass gasifier is used in practical applications. There are still many problems in the process. If these problems are not solved, it will affect the prospects of the biomass gasifier. For example, the "ashing" problem of the biomass gasifier is an example.

Before the patent application of the present invention, such as ZL201120013927.0 "Double Helical Roller Ash Discharge Device for Gasifier", the ash discharge problem of biomass gasifier was discussed, and it was practical, but in most cases, ash discharge from the side was adopted. method or device, that is, when the biomass gasifier is out of use, the ash in the biomass gasifier is pulled out from the ash outlet with a special hook or rake. Although this process or tool can remove the ash However, part of the carbonized or semi-carbonized materials in the furnace will also be discharged out of the furnace when the ash is removed, and in many cases the ash and slag cannot be removed cleanly, which will affect the use of the biomass gasifier and even affect the gasification Effect
