Domestic coking tower bottom valve reaches the international advanced level

As of August 14th, the coking tower bottom valve developed and produced by the Lanzhou Petrochemical Company Machinery Plant and reaching the international advanced level used the delayed coking unit of the company for more than one month to smoothly unwind the 20 towers, and its technical performance fully satisfied the production. need.
China's current coking capacity has exceeded 21 million tons annually. More than 30 refineries have more than 60 sets of coking devices, and more than 100 coke drums have been used. Coke towers have not adopted a closed pipeline system for coking towers. Dismantling the bottom blind cover and feed pipe flange, which weighs several tons, is not only cumbersome and labor-intensive, but also requires long time for auxiliary operations. Moreover, the operator is easily burned by water and steam, and a large amount of cold coke water discharge is not conducive to Environmental protection.
In 2005, Lanzhou Petrochemical Machinery Factory began to work on the development of coking tower valves. After nearly three years of hard work, it finally completed assembly in early May of this year and passed expert appraisal. With the support of this company and related units, the delayed coking unit was put into the industrial assessment test in early July.
The coking tower bottom valve uses a fast high-power electrohydraulic actuator to open or close the tower bottom valve within 4 minutes. The interlocking design of the relevant process parameters of the coking unit is used to ensure safety and reliability. Steam consumption at the bottom of the coking drum The indicators such as opening and closing time are better than those of foreign countries. At present, there are already a number of refineries who express their intentions of ordering. Lanzhou Petrochemical Machinery Factory is making efforts to put it into production. In the development and production process of the coking tower bottom valve, Lanzhou Petrochemical Machinery Plant applied for a patent and formed 6 proprietary technologies.
