摘要： PROBLEM TO BE SOLVED: To pre-treat organic gas which becomes a nutrient source for the growth of microorganisms contained in gas and to prevent the clogging of a treatment unit by providing a water spray means in an introduction pipe of odorous gas and also providing washing means of a packed bed in the upper and lower parts of the packed bed in a pretreatment device provided with the water spray means in the upper part of the packed bed in a tower body. SOLUTION: Odorous gas collected from a bit system and a conveyor system is sent into a hollow duct 13 which is an introduction pipe of odorous gas supplied to a pretreatment device 1. Odorous gas is primarily washed by hollow sprinklers 7 provided in the hollow duct 13 and a hollow water spray pump 8. Primarily washed odorous gas is secondarily washed through a packed bed 2 in which a water screen is formed by water spray sent from a sprinkler 5 for the packed bed and thereafter odorous gas is sent to a biodeodorization tower. Further, when multiplying and growing microorganisms stick to the packed bed 2 by operation for a long period and choking is caused in the pretreatment device 1, these stuck microorganisms are removed by water spray of high pressure water 11 sent from self-pressure rotation type high pressure washing nozzles 4 and thereby choking is prevented.

摘要： PURPOSE:To prevent generation of a trouble of fusing of ash component and to relize a stable operation in a treatment of combustible waste by using a thermal cracking furnace. CONSTITUTION:When combustible waste is thermally cracked by a thermal cracking furnace and a thermally cracked remain is afterburned in an afterburning chamber 6, a part connecting a generated gas outlet space of the thermal cracking furnace and a space for afterburning of the thermally cracked remain is given gas flow resistance by a thermally cracked remain filled layer 20 or a breaking valve 27, so that gases in the both spaces can be prevented from mixing with each other. A recombusting chamber 5 to burn gas generated in the course of the thermal cracking and the after-burning chamber 6 to afterburn the remain are arranged in the same furnace space. In addition, the thermal cracking furnace and the afterburning chamber 6 are connected through a remain transfer conveyor 21 to keep heat held by the remain as much as possible and to promote ashing.

摘要： PURPOSE:To prevent the blockage due to dust deposition in an oven gas duct of a dry distillation oven of continuous molded-coke production equipment. CONSTITUTION:A gas chamber 21 is installed in an oven gas duct 22 of a dry distillation oven 3. The blockage in the duct is prevented by keeping the inner wall of the gas chamber 21 always covered with a film of a part 23 of a recirculating tar 24 from a heat recovery tower 5 or with a film of a hot ammonia water 23-a from a gas-cooling unit 5a. Since the inner walls of the oven gas ducts 22 and 25 are always covered with the film of the tar or the hot ammonia water, the adherent dust is always flown and removed, thus preventing the blockage.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for cleaning gasified gas, by which the adsorption capacity is effectively recovered and a maintaining gas-cleaning performance of the apparatus is achieved, even when the adsorption capacity is decreased by adsorbing high-boiling hydrocarbon compounds in gasified gas. SOLUTION: A gasified gas obtained by thermally decomposing organic waste or solid organic matter such as coal is cooled to a temperature of 60°C or lower to remove water mist, tar components of a liquid hydrocarbon, and solid dusts included in the cooled gasified gas, before the gas is passed through activated carbon adsorption device 1 composed of activated carbon adsorption columns 1a and 1b. The cooled gasified gas is then heated, and passed through the activated carbon adsorption device 1. Feed of the gasified gas is interrupted and steam is fed to those adsorption columns the adsorption capacity of which is decreased due to the adsorption of high-boiling hydrocarbon compounds to release the high-boiling hydrocarbon compounds. The released high-boiling hydrocarbon compounds are discharged to the steam side as waste steam. After the adsorption capacity is restored, feed of the gasified gas is resumed.
