Splitting decomposition gasification furnace shaftless spiral wind-locking feeding device and feeding method thereof

Abstract

The invention provides a splitting decomposition gasification furnace shaftless spiral wind-locking feeding device and a feeding method thereof. The splitting decomposition gasification furnace shaftless spiral wind-locking feeding device comprises a machine shell, a driving mechanism and two or more shaftless spiral bodies. The machine shell is provided with a feeding port and a discharging port.All the shaftless spiral bodies are arranged in parallel and side by side in a cavity of the machine shell. The driving mechanism and the shaftless spiral bodies are connected so that the shaftless spiral bodies can be driven. Rotating directions of any two adjacent shaftless spiral bodies are opposite. In the running process, materials entering from the feeding port enter a splitting decomposition gasification furnace gradually from the discharging port under the propelling action of the shaftless spiral bodies; continuous feeding as required can be effectively achieved; uniform distributionand the reaction process of the materials in the splitting decomposition gasification furnace are benefited; and material blocking and winding are avoided so that feeding is smoother. The feeding port of the splitting decomposition gasification furnace can be effectively segregated from outside air by the materials and the shaftless spiral bodies, the wind-locking effect is achieved, and it is avoided that the furnace body is frequently opened for feeding and thus the oxygen-free or anaerobic environment in the furnace is destroyed.

Description

technical field [0001] The invention relates to the field of fixed waste disposal, in particular to a shaftless spiral airlock feeding device for a cracking gasification furnace and a feeding method thereof. Background technique [0002] The current pyrolysis gasifier generally adopts the way of feeding by garbage crane or conveying mechanism. When the material enters the cracking gasifier, it is necessary to open the feed port on the top of the cracking gasifier. At this time, some air will enter the cracking gasifier, thus destroying the anaerobic or anaerobic atmosphere in the cracking gasifier. oxygen environment. In the process of using garbage cranes or conveying mechanisms to transport materials, because of the large amount of material entering the furnace at a time, it is easy to cause material accumulation in the furnace, which is not conducive to the realization of the cracking process. In addition, when the material is pushed through the conventional rotating sh...
