Problems solved by technology

However, due to the establishment of the internal ash discharge pipe, according to the requirements of the installation process of the internal ash discharge pipe, the total area of ​​the ash discharge pipe is limited, and the ash discharge effect is poor. Moreover, the design of the air pipe passing through the vibrating screen makes the installation process difficult. Relatively complex, especially for the complex environment in the gasifier furnace, it is difficult to ensure the free vibration of the vibrating screen

Abstract

The invention discloses a biomass gasification furnace convenient for air inlet and ash discharge. A bottom-top feeding way is adopted. A hearth comprises a feeding pipe, a hearth air inlet device and an ash discharge device, wherein the hearth air inlet device and the ash discharge device are arranged on the bottom inside the hearth and arranged surrounding the feeding pipe or a feeding opening in the hearth; annular air ducts (21) in the hearth air inlet device is arranged above a vibrating sieve (7) in the ash discharge device, and the annular air duct (21) is connected with the vibrating sieve (7). The annular air duct and the vibrating sieve vibrate simultaneously, the annular air ducts and the air pipe also can vibrate simultaneously, so that not only can the uniformity in air feeding in the hearth be favored, but also a good effect of loosening the ash in the hearth can be realized, and the ash can be conveniently discharged.

Description

technical field [0001] The invention belongs to household furnaces or stoves with solid fuels, and relates to a biomass gasification furnace which is beneficial to uniform air intake and ash discharge, and is mainly aimed at improving the device of the annular air duct in the furnace and the ash discharge method. Background technique [0002] At present, only one annular air duct is installed in the furnace of the biomass gasifier that uses annular air duct to blow air, which will cause uneven wind field and air pressure in the furnace. If the furnace is to work normally, the local temperature of the fuel in the furnace will exceed 800 degrees, which is easy Generate slagging (fuel slagging temperature is generally 680 degrees), because slagging will affect the ventilation performance of the furnace, so that the gasifier cannot work continuously for a long time. Therefore, there is a need for a furnace air intake and ash discharge device that is conducive to discharging the ...
