The device is the design of the equipment of the pressure gasification plant of the device is the design of the limited liability pany of the tripod Engineering Co.. The device is posed of a 22 sets of pulverized coal pressurized gasification furnace (including coal chute, coal lock, gasifier, washing cooler, ash lock, waste heat boiler etc. equipment), according to the arrangement of the framework of three, of which a and C frame each 7 units of the gasifier, the B framework for 8 sets of gasifier. Total gas production 946524Nm3/h (dry basis), single furnace production capacity of 43024Nm3/h, total coal consumption 582t/h, total oxygen consumption 126280Nm3/h, total steam consumption gasification furnace while the configuration of the ash lock and auxiliary hydraulic deslagging system. The ash lock and hydraulic slag removal system of closely coordinated, for gasification furnace slag ash like human excretory system is essential, in order to guarantee the normal production of the gasification furnace. First introduced ash lock and hydraulic slag removal in the gasification furnace section position, status and role, secondly for Xintian coal chemical coal gas, ash lock ash and hydraulic slag removal process involved in the technology detailed preliminary analysis (including the ash lock, principle and process of hydraulic slag removal process, open parking operation procedures, technical parameters and mon troubleshooting). Then the ash lock, used in hydraulic slag removal system of bridge type grab machine equipment open parking operation step points to conduct a detailed analysis, at the end of this paper, the ash lock and hydraulic slag removal system of the exception handling. Keywords: The ash lock。 Hydraulic discharge。 Process。 Gist。 Fault handling 克拉瑪依職業(yè)技術學院畢業(yè)設計（論文） 5 目錄 一 .概述 .......................................................................................................................................................................................... 1 裝置概況 ........................................................................................................................................................................... 1 灰鎖及水力排渣 .............................................................................................................................................................. 1 灰鎖排灰 ..................................................................................................................................................................1 排渣系統(tǒng) ..................................................................................................................................................................1 崗位職責 ........................................................................................................................................................................... 2 灰鎖崗位職責 .........................................................................................................................................................2 排渣崗位職責 .........................................................................................................................................................2 管轄范圍 ........................................................................................................................................................................... 2 灰鎖崗位管轄范圍 ................................................................................................................................................2 排渣崗位管轄范圍 ......................................................................
