Description
Technical field
The utility model relates to the burnt water circulation treatment device technical field of System of Cool Coking of Delayed Coking in a kind of refinery.
Background technology
The coke cooling water treatment unit is to adopt traditional open type circulating disposal process in China's refinery delayed coking unit, it is the open type discharging, the parallel flow intercepter oil removal, water cooling tower cools and water pump lifting is given water-cooled Jiao's circulating disposal process and device, coke tower is given in the process of water cooling coke layer after finishing the pyrogenic reaction process, cat head high temperature overflow water and big amount temperature are being carried oil whip secretly and micro-coke powder is discharged to oil trap along upflow tube at 150 degree left and right sides high-temperature steams, a large amount of volatile organic compounds VOC evaporations enter in the air in the sewage, oil trap ingress steam fills the air, and distributes the intensive stench.All adopt the extracting of coke cooling water pump to water cooling tower air blast cooling to the cooling of coke cooling water in the world, because evaporable organism quilt stripping, evaporation, loss constantly easily in the high temperature coke cooling water, form a stench face source that range of influence is bigger, stench concentration is the highest can be reached 2000 and (presses the GB/T14675 method, surrounding enviroment are caused severe contamination down together).Its concrete problem that exists has:
1, existing circulating disposal process and device oil removing cooling-down effect are poor, China System of Cool Coking of Delayed Coking Jiao Shui adopts circulating disposal process mostly, the coke cooling water oil concentration usually is higher than 400mg/l, even above 2000mg/l, water cooling tower is adhered to and stops up by oil easily, and cooling-down effect is poor, when device go into operation to later stage coke cooling water temperature can up to 90 the degree, restrict the processing power of device, influenced normal production;
2, existing circulating disposal process and device context pollution problem are outstanding, coke cooling water is carried heavy oil secretly, coke cooling water contains big gauging, sulphur, phenol, cyanogen, heavy metal, heterocycle and condensed-nuclei aromatics compound, wherein relatively enrichment of carcinogenic substance such as heterocycle and condensed-nuclei aromatics, in the burnt water process of the cooling of water cooling tower, evaporable heavy oil oil gas and hydrogen sulfide pollute surrounding environment, and population health is constituted a threat to;
3, the intractability of coke cooling water is big, and the coke cooling water intractability is bigger, and coke cooling water is obviously different with other oily(waste)water, and in its component, the initial stage is a three-phase mixture, vapor temperature 100 the degree more than, oily(waste)water, coke powder.Oil density in the oily(waste)water therein reaches 0.9396mg/cm
3Very approaching with the density of water, in coke powder, the oil suction of porous coke powder alleviates, part coke powder proportion is less than water, mix floating in the oil, the part coke powder is deposited on the bottom greater than water, the part coke powder is identical with water proportion, mix to float in the water, these characteristics have determined the closed processes difficulty of coke cooling water, also are the roots of sedimentation oil removal facility poor effect step by step;
4, coke cooling water hot tub steam fills the air, and is seriously polluted because the coke cooling water that the cold burnt initial stage overflows from the coke cat head is carried a large amount of steam secretly, advance retention basin after, make vaporizing oil-gas with a large amount of steam raisings in atmosphere, have a strong impact on surrounding environment.
