Gasification furnace built-in tar gasification circulating system

Abstract

The invention relates to a gasification furnace built-in tar gasification circulating system which comprises a feeder, a gasifier and a separation cooler which are sequentially connected, wherein the gasifier comprises a furnace body; the top of furnace body is provided with an automatic cover opening / closing mechanism; the outside of the furnace body is connected with an air intake mechanism and a cooling mechanism; the bottom of the furnace body is provided with an ash discharge mechanism; a tar gasifier is arranged above the ash discharge mechanism; the tar gasification mechanism comprises an inner liner and an outer liner; the top and bottom of the region between the inner liner and outer liner are respectively provided with a seal-structure upper cover and a bottom plate which is uniformly distributed with small holes; a gasifying agent is arranged on the bottom plate; wood charcoal generated by gasified biomass falls on the ash discharge mechanism and is accumulated in the inner liner; and the outer side of the outer liner is provided with a gas outlet pipe and the separation cooler. The gasification furnace built-in tar gasification circulating system is reasonable in design, simple to operate and convenient for maintenance, and has the advantages of high safety linkage coefficient, high automation degree, high continuous gas production capacity and high gas purity. The gasification furnace built-in tar gasification circulating system performs circulating gasification on the tar generated by the reaction, so the fume and tar emissions are low, thereby greatly lowering the environment pollution and especially air pollution.

Description

technical field [0001] The invention relates to the technical field of solid fuel combustion equipment, in particular to a built-in tar gasification circulation system of a gasification furnace. Background technique [0002] The combustible gas produced by the biomass gas furnace belongs to green new energy and has strong vitality. Since the raw materials of plant gas are crop straw, forest waste, edible fungus residue, cattle, sheep and livestock dung and all combustible substances, it is an inexhaustible renewable resource. Each farmer only needs 3-5 kilograms of plant raw materials per day to solve the daily energy consumption (cooking, heating, showering), and burn like liquefied petroleum gas, which can completely change the smoky life style in rural areas of our country. Traditional firewood stoves can be banned and liquefied petroleum gas can be replaced. [0003] The existing biomass gasifier has high technical requirements in the operation process, troublesome use...
