Abstract

The invention relates to a pneumatic coke powder removal device for a delayed coking fractionating tower.The device comprises a plurality of pneumatic cyclone coke powder removal units, a hollow cylinder, an upper sealing plate and a lower sealing plate, the pneumatic cyclone coke powder removal units, the upper sealing plate and the lower sealing plate are all arranged in the hollow cylinder, the number of the pneumatic cyclone coke powder removal units is multiple, the multiple pneumatic cyclone decoking powder units are tightly connected with the hollow cylinder through the upper sealing plate and the lower sealing plate, and the central axis of each pneumatic cyclone decoking powder unit is parallel to or coincides with the central axis of the hollow cylinder. According to the device, the content of coke powder in coker gas oil is reduced by reducing the content of coke powder in coker gas oil, and meanwhile, coking at the bottom of a fractionating tower can be controlled. The device is low in investment cost, high in reliability, long in continuous operation period and high in coke powder removal efficiency, and can be applied to the delayed coking fractionating tower or coke powder removal equipment outside the delayed coking fractionating tower.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a device for removing coke powder pneumatically in a delayed coking fractionation tower, a use method and an application. Background technique [0002] Due to its mature technology, low investment and operating costs, the delayed coking process can convert various heavy residues (or dirty oils) into liquid products and special petroleum coke, greatly increasing the diesel-to-gasoline ratio of refineries. Especially with the development and application of residual oil / petroleum coke gasification technology and coking-gasification-gas-electricity cogeneration process, the delayed coking process is still the primary method for deep processing of residual oil. At present, domestic delayed coking units There are generally problems such as large amount of coke powder carried by coking oil and gas, poor washing effect in the washing section of the fractionating tower, a...
