Technical Field
The utility model relates to a biomass gasified gas purification system in a high-temperature state, wherein biomass comprises crop straws and shells, forestry three residues, minor firewood, bamboo residues, sludge, household garbage and the like.
Background
At present, when biomass gasification, biomass gasification gas can mix with a large amount of dust when producing, if not handling, these dusts can get into burning in boiler or the kiln along with biomass gasification gas, and then adhere to boiler inner wall, lead to boiler inner wall scale deposit, increased boiler operation and maintenance volume and cost, influence boiler availability factor, perhaps get into burning in the kiln, influence the quality of calcination product in the kiln. Therefore, the biomass gasified gas needs to be purified before entering the boiler, so that the requirements of the boiler and the kiln on safety, economic operation and product quality are met, and the boiler economy, safe operation and product quality have important significance on economic development and environmental protection.
The conventional dust removal device filters smoke by adopting a filter bag made of chemical fiber materials, and the highest service temperature is not more than 260 ℃ generally in order to prolong the service life of the filter bag.
Disclosure of Invention
The utility model aims to provide a biomass gasified gas purification system in a high-temperature state, and mainly solves the technical problems that in the prior art, the temperature of biomass gasified gas is too high when dust is removed before the biomass gasified gas enters a boiler and a kiln, a conventional dust removal device cannot bear the high temperature of more than 260 ℃, the use of subsequent gasified gas is influenced without removing dust, the system efficiency is influenced by reducing the temperature of the gasified gas, and the like.
The purpose of the utility model can be realized by the following technical scheme: the utility model provides a living beings gasification gas clean system under high temperature state, includes living beings feed bin, living beings gasification equipment, living beings gasification gas pipeline, high temperature dust collector, air-blower and boiler or kiln, and living beings feed bin passes through the feed inlet and connects living beings gasification equipment, and living beings gasification equipment passes through living beings gasification gas pipeline and connects high temperature dust collector, and high temperature dust collector passes through pipeline and air-blower connection boiler or kiln. The high-temperature dust removal device is internally provided with a high-temperature metal bag type dust remover or a ceramic bag type dust remover, all pipelines are provided with valves, and the materials of the pipelines are seamless stainless steel pipes.
The utility model has the beneficial effects that: because the biomass gasified gas is subjected to the dust removal process before entering the boiler, the ash removal is not needed in the boiler, and the rear flue of the boiler is not needed to be arrangedA dust removing device. The utility model has the following two characteristics: 1. the high-temperature metal or ceramic dust remover can effectively remove dust of biomass gasified gas at a high temperature, and has long service life. 2. The operation, maintenance and cost of the boiler can be reduced, so that the efficiency of the boiler is improved, and the quality of the calcined product of the kiln is ensured. The highest temperature resistance of the high-temperature metal or ceramic filter bag can reach 800 ℃; the dust removal efficiency is high, and the optimal dust removal efficiency can reach 5mg/Nm2(ii) a The running resistance is as low as 600-1500 Pa; the service life can reach more than 5 years.
