Sealed discharging method and continuous sealed discharging device

Abstract

The invention provides a sealed discharging method and a continuous sealed discharging device. The sealed discharging method comprises the following steps: arranging a hollow horizontal channel between a feed inlet and a discharge outlet and a reciprocatingly-moving discharging tackle in the horizontal channel and allowing the discharging tackle and the inner wall of the horizontal channel to be in sealed contact; allowing the discharging tackle to seal the feed inlet before discharging; during discharging, allowing the discharging tackle to move in the horizontal channel towards a direction away from the discharge outlet, opening the feed inlet and allowing a material to fall into the horizontal channel; and then allowing the discharging tackle to move towards the discharge outlet so as to push the material to the feed inlet. The sealed discharging method and the continuous sealed discharging device used for a biomass carbonization furnace in the invention enable excellent sealing effects to be obtained during working and shutdown by using the manners of static sealing and dynamic sealing.

Description

technical field [0001] The invention relates to the field of biomass carbonization, in particular to a sealed discharge method and a continuous sealed discharge device for a biomass carbonization furnace. Background technique [0002] Energy and environmental issues have become the focus of global attention. The massive consumption of fossil fuels has brought serious environmental pollution and ecological damage, coupled with the dwindling of resources such as coal, oil, and natural gas, the development of clean and renewable energy has become an urgent need for sustainable development. Biomass energy is an important renewable energy source on earth. The total production of organisms on the earth is as high as 1400t to 1800t per year, which is equivalent to 10 times of the world's total energy, and has great potential for development and utilization. Therefore, the development and utilization of biomass energy is of great significance for alleviating energy, environmental ...

AI Technical Summary

Problems solved by technology

However, kiln firing carbonization and dry distillation carbonization have the disadvantages of serious pollution, low yield in the carbonization process, and non-continuous production.

Microwave carbonization requires very high energy consumption, the energy consumption ratio is low, and there is no possibility of large-scale application

Bio-pyrolysis carbonization has high requirements on raw materials and complicated technology, so it can only stay in the laboratory stage

[0004] At present, the more efficient carbonization method adopted is to use the method of carbonization in the carbonization furnace for production. However, the traditional carbonization furnace cannot realize continuous discharge during discharge because of the simple movable furnace tray discharge method, and it is easy to cause material The collapsing vortex of the layer makes the biomass raw material and biomass carbonized material mix and fall, which affects the carbonization effect of biomass raw material

And because there is no separate discharge sealing device, there is the disadvantage that it cannot be effectively sealed during discharge and carbonization, resulting in too high oxygen content during the carbonization process, thereby reducing the carbon content of the final carbonization material and increasing the ash content, so it must be There is a more efficient carbonization furnace sealing device used with the carbonization furnace to improve the quality of the carbonization material
