Preheating device for coking tower

Abstract

The invention provides a preheating device for a coking tower. The preheating device structurally comprises a wheel carrier, an air pressure tank, an electromagnetic heating box and an air pressure pump, wherein the wheel carrier is movably connected with the air pressure pump; the air pressure tank is connected with the air pressure pump; the electromagnetic heating box is arranged on the air pressure pump; the wheel carrier comprises movable wheels and rotary tables; the movable wheels are movably connected with the wheel carrier by the rotary tables; the air pressure tank comprises a controller, a retainer ring and an interface. According to the preheating device for the coking tower, lifting and uniform heating of equipment are realized by arranging the wheel carrier, the air pressuretank, the electromagnetic heating box, the air pressure pump, heating wires and a lifting pump rod; the equipment is provided with the air pressure tank for supplying pressure to the air pressure pump, and the lifting pump rod is controlled to lift the electromagnetic heating box, so that the electromagnetic heating box can switch at different heights for work; the electromagnetic heating box is provided with the electromagnetic heating wires for uniformly heating the coking tower; in addition, the equipment is also provided with the wheel carrier for moving the equipment more conveniently andfacilitating uniform heating of the coking tower.

Description

technical field [0001] The invention is a coke tower preheating device, which belongs to the field of coke towers. Background technique [0002] The coke tower is the equipment for delayed coking. Delayed coking is a secondary processing technology of petroleum. It uses hydrogen-poor heavy oil as raw material. The high-temperature medium-heavy oil undergoes deep thermal cracking and condensation reactions, and the gas, gasoline, diesel oil, and wax oil produced are transported to downstream devices for processing through pipelines, and hundreds of thousands of tons of coke produced remain in the coke tower. The coke in the coke tower is gradually cooled to below 120°C by steam and water, then the upper and lower switch cover equipment of the coke tower is opened, and the coke in the coke tower is cleaned by the hydraulic decoking equipment, and then the upper and lower switch cover equipment is closed to enter the next step Production cycle: oil feed, reaction, cooling, dec...

AI Technical Summary

Problems solved by technology

However, the device does not have a clear heating method, and it is only heated by a fixed heating device on the tower body, which easily leads to the problem of uneven heating, and it is also inconvenient to install and disassemble.
