Problems solved by technology

[0012] Simply relying on the purification method of "gas separation, condensation, gas collection, and suspension separation", although "the process is simple", it is only a passive method of using physical suspension. This purification method cannot improve the tar cracking rate and gasification. Comprehensive economic benefits of rate and gas calorific value

Embodiment Construction

[0024] Below in conjunction with embodiment the present invention will be further described:

[0025] figure 1 It is a schematic diagram of the biomass gasification furnace purification system.

[0026] When the gas flow of the biomass gasification furnace 1 passes through the pipeline 2 and flows through the catalyst 4 of the biomass gasification furnace in the catalytic converter 3, the tar in the gas flow is catalytically cracked, and the cracked tar is decomposed into combustible Gas and other substances are transported from the pipeline 6 to the labyrinth gas holder 7 along with the gas flow, and tar, alkali metals, heavy metals, waste water and dust that have not been cracked are blocked by numerous particle catalysts in the labyrinth. Combined with the effect of gravity, it flows into the waste tar and waste water chamber 5, and flows from the lower pipe 12 of the catalytic converter to the collection pool 14 of waste tar and waste water.

[0027] The gas flow purifie...

Abstract

This invention discloses a biomass gasification furnace purification system. the main points of its technical proposal is that the system is consisted by catalysis ware, catalyst, labyrinth type gasometer, adsorption filter, adsorption filtering agent, waste tar and waste water collecting pit. Fuel gas current of biomass gasification furnace is transferred to labyrinth type gasometer through catalyst in the catalyst ware, then it istrasferred to adsorption filtering agent in the adsorption filter, the fuel gas current after three times purification is transferred to burner, and the whole purification course is finished. This invention is used to biomass gasification furnace purification system, its structure is simple, cost is low, and operation is simple. Water bath is not used in the system, the waste tar and water is few, and can be value things after proposed. The tar cracking ratio and gas current heating value is high, and the rate of gasification of the furnace can be improved. There is no environmental pollution.

Description

Technical field: [0001] The invention relates to a biomass gasification furnace, in particular to a biomass gasification furnace purification system. Background technique: [0002] In the early 1980s, my country began to study biomass thermal decomposition gasification technology, and developed various forms of gasifiers. Biomass is a kind of renewable energy with abundant reserves. It can be used as an alternative energy source to realize CO 2 Zero emissions, and low S, N content, greatly reduce the greenhouse effect and environmental pollution. [0003] At present, the main problem of domestic biomass gasification technology is that the calorific value of gas is low, and the tar produced in the gasification process is more, which makes it difficult to purify the gas and affects the normal operation of the gasifier. The gas purification system usually adopts simple water washing treatment, which not only causes serious pollution of the washing water, but also is not condu...
