Straw gasification furnace

Abstract

The invention discloses a straw gasification furnace which comprises a furnace body, a furnace cover, an air inlet port, a fuel gas outlet port, a furnace grate arranged on the lower part of the furnace, an ash-removing port and a sealing door. The fuel gas outlet port of the furnace body is provided with a tar filter; the tar filter comprises a box body and tar filtering plates superposed at theinner part of the box body; and the upper part of the box body is provided with an air outlet port, and the lower part is provided with an air inlet port communicated with the fuel gas outlet port ofthe furnace body. Tar filtered by the straw gasification furnace directly returns to fuel to be involved in schizolysis and combustion, and the content of water vapour in combustible gas can not be increased when the tar in the combustible gas is filtered.

Description

technical field [0001] The invention relates to a stove, in particular to a straw gasification furnace. Background technique [0002] The straw gasification furnace converts raw materials such as various crop straws, wood processing residues and industrial organic wastes into high-quality, clean and efficient gas through closed anaerobic combustion. The advantage of low cost. However, the straw gasification furnace will produce tar while producing combustible gas. After the tar is evaporated, it will be mixed with the combustible gas and reach the gas stove through the gas supply pipeline, which will emit a pungent smell. When the temperature of the gas supply pipeline is low, the tar vapor will Condensation in the pipeline, causing pipeline blockage, Chinese utility model patent CN2813615 discloses an aspirated multi-stage filter straw gasifier with tar filtering function, the straw gasifier uses combustible gas passing through the water level partition water Membrane to ...

However, the straw gasification furnace will produce tar while producing combustible gas. After the tar is evaporated, it will be mixed with the combustible gas and reach the gas stove through the gas supply pipeline, which will emit a pungent smell. When the temperature of the gas supply pipeline is low, the tar vapor will Condensation in the pipeline, causing pipeline blockage, Chinese utility model patent CN2813615 discloses an aspirated multi-stage filter straw gasifier with tar filtering function, the straw gasifier uses combustible gas passing through the water level partition water Membrane to filter out tar, using this method to filter tar exists, the filtered tar is mixed with water, it is not easy to collect and treat, and it is easy to cause environmental pollution, and the combustible components in tar cannot be fully utilized. The water vapor content in the gas is not conducive to combustion, and it is necessary to add drying or condensation equipment to remove water vapor, which increases the manufacturing cost
