Petroleum coke transportation, dehydration and storage equipment for delayed coking

Abstract

The invention relates to petroleum coke transportation, dehydration and storage equipment for delayed coking. The equipment consists of a coke water separator, dehydration tanks, a purified water temporary storage tank, a coke conveyor, coke storage tanks and the like. The coke water separator is internally equipped with a horizontal conveying mechanism suspended above the internal bottom surface,the horizontal conveying mechanism is equipped with sieve holes for water to pass through, the end of the horizontal conveying mechanism is connected to the coke storage tanks through the coke conveyor, a coke water mixture output from a lower water outlet of the coke water separator is conveyed to the dehydration tanks, and the dehydration tanks are respectively connected to the coke storage tanks and purified water temporary storage tank. The equipment changes the coke concentrated dehydration way to a distributed treatment way of dehydrating granular coke of different sizes separately, thetreatment speed is faster, the efficiency is higher, and the amount of coke needing treatment by dehydration tanks and other single component can be substantially reduced, thus being more conducive to optimal process control. When the amount of coke or water discharged by coke towers in a moment is too large, the volumetric overlay buffering effect of the components can effectively prevent spillover, thus ensuring continuous operation of the petroleum coke airtight conveying system.

Description

technical field [0001] The invention relates to a petroleum coke processing system of a delayed coking unit, in particular to a petroleum coke transportation, dehydration and storage equipment for delayed coking. Background technique [0002] Delayed coking is a kind of petroleum processing technology. It uses heavy oil as raw material. It is heated rapidly to the coking reaction temperature of about 500°C through a heating furnace, and then enters the coke tower for coking reaction. After the reaction is completed, the high-temperature coke is cooled by steam and water, and then cut and decoked by high-pressure water. The coke and water mixture produced in this process is discharged into the coke pool for separation of coke and water. The mixture of coke and water entrains a large number of odorous chemical substances, mainly hydrogen sulfide, mercaptans, sulfides, hydrocarbons, organic halogen derivatives and other volatile organic compounds (VOC), most of which are harmf...

Problems solved by technology

On the one hand, this processing method requires a large amount of coke-water mixture to be processed in the dehydration bin or dehydration tank, and the processing speed is slow; on the other hand, the centralized processing method requires relatively large processing equipment, and relatively high requirements for site area and layout. , it is more difficult to realize, and the equipment cost is also higher
