三套焦化高压泵房除焦控制方案(论文5000字)
摘  要
水力除焦系统是用高压水泵将把除焦水通过工艺管线在钻具的喷嘴处汇聚成高压高速的线束，利用此线束来将焦碳切碎，从而达到除焦的目的。
有井架水力除焦设备是以井架为基体，钻机绞车安装于井架底部的旁侧。钢丝绳一端固定于钻机绞车卷筒上，另一端通过导向滑轮，将固定式滑轮组、游动式滑轮组联结成一个滑轮组系，终端用钢丝绳夹、套环与游动式滑轮组固定。
滑轮组下端与风动水龙头连接，往下依次为钻杆、自动切换切焦焦器。
除焦时，除焦水由高压水泵泵出，经由除焦控制阀、工艺管线、风动水龙头，最后进入自动切换切焦器，由切焦器的喷嘴射出。
进行除焦的执行机构是钻孔切焦器，高压水通过切焦器斜向下的喷嘴射出高压水在成塔焦碳的中心处从塔顶至下钻出一个通孔，然后堵住切焦器钻孔喷嘴，打开切焦器水平喷嘴，从中射出高压水进行成塔焦碳的切焦，切下的焦碳从塔中心孔及除焦通道中滑至料场，此过程一直到整塔焦碳除完。

Abstract

Hydraulic decoking system with high pressure water pump will decoking water through the pipeline in the nozzle hole of the converging wire harness high speed, using the wire harness to the coke cutting, so as to achieve the purpose of removing coke. [资料来源：Doc163.com]
Hydraulic decoking equipment with derrick base derrick, drawworks side mounted on the bottom of the derrick. One end of the wire rope is fixed on the drawworks drum, the other end of the guide pulley and the fixed pulley group, moving pulley connected with a pulley, wire rope clamp, terminal ring and moving pulleys fixed.
The pulley and the lower end of the pneumatic faucet connection, turn down pipe, automatic switching device cut coke.
In addition to coke, coke removing water from the high-pressure water pump, through the decoking process pipeline and pneumatic control valve, faucet, and finally into the automatic switching of coke cutter, injection nozzle by coke cutter.
In addition to the actuator is drilling coke coke cutter, high pressure water through the coke cutter inclined downward pressure water injection nozzles in the coke tower from the top of the tower at the center of to drill a hole, and then blocked the coke cutter drilling nozzle, open coke cutter horizontal nozzle, cut from the high-pressure water injection coke tower, cut off from the coke tower center hole and decoking channel slip into the yard, this process has been to the end in coke tower.
