Closed petroleum coke dewatering-storage-transport facility

Abstract

The invention relates to a closed petroleum coke dewatering-storage-transport facility. According to the technical scheme, the facility comprises coke towers, inclined chutes, a closed shed, a bridge-type material pushing crushing machine, a push plate, petroleum coke, a material bin, metal needles, a sedimentation pond, a crane track column, an inclined support, a spiral material pushing machine,a grabbing crane, a buffer hopper, a spiral drain pipe, an external-transport operation chamber, an inclined spiral elevator, a flat gate valve, a coke removal water inlet, a coke removal water outlet, a tail gas output port, a coke storage pond, a grid and a crane track. The problems are emphatically solved that when petroleum coke is prepared into coke, oil gas volatilization is large, harmfulgas pollutes the environment, coke powder is blown by wind and flies everywhere in the outdoor storage process of the petroleum coke, the water content of the petroleum coke cannot be guaranteed on rainy days, and the coke powder is scattered everywhere when the bridge-type grabbing crane loads and transports the coke powder during external transport.

Description

technical field [0001] The invention belongs to the field of coke decoking and relates to a closed petroleum coke dehydration, storage and transportation facility. Background technique [0002] At present, there are more than 150 sets of delayed coking units in domestic refineries, and petroleum coke is the final product produced by delayed coking units. Since the petroleum coke produced in the coke tower has a temperature of more than 460 degrees, it must be cooled by steam and water, and then crushed by hydraulic decoking. The crushed petroleum coke and decoking water fall into the coke tower through the coke chute by gravity In the lower coke storage pool. The cooling of petroleum coke is carried out from bottom to top through the central hole in the coke tower. First, steam at 250 degrees is introduced at the bottom of the coke tower to take away part of the heat of the petroleum coke, and then continue to cool down with cooling water. Using the above cooling method, t...

AI Technical Summary

Problems solved by technology

[0007] Combined with the mature and reliable method of petcoke in the background technology falling into the coke storage pool through the coke chute, the focus is on solving the problem that when the coke in the background technology flows coke, the oil and gas volatilizes and the harmful gas pollutes the environment. The moisture content of petroleum coke cannot be guaranteed in rainy days, and the coke powder is scattered everywhere when transported by bridge grab cranes.
