Abstract
The utility model relates to an environmental protection technology field, a cold burnt tail gas recycle system of coke drum specifically says so. Including the coke drum, the coke drum divides fluid reservoir and water wash column to be connected through putting void tower, and the other end of water wash column links to each other with the compressor through distillating fractionally the top of the tower water -cooling. Cold burnt tail gas recycle system of coke drum has solved environmental pollution's problem, and tail gas is retrieved simultaneously, incorporates the tail gas that discharges into suction port of compressor, has reached energy saving and consumption reduction's purpose, has avoided the fluctuation of pipe network simultaneously, and it is not enough to add system hydrogen raw, and it is undulant to have avoided relating to each device that uses fuel gas simultaneously, avoids abnormal conditions to take place, has reduced the economic loss of company, alleviates pipe network pressure, reaches energy saving and consumption reduction, and discarded object, meet the State standards are not discharged in assurance simultaneously. Easy operation invests in for a short time, has high repayment.
Description
Technical field
This utility model relates to environmental technology field, the cold burnt tail gas recycling system of a kind of coke drum.
Background technology
At present, Coking Tower for Delayed Coking Unit, during cold Jiao, steams out greatly, coke drum oil gas rushes to torch and burns
Falling, for full factory system, fuel gas only has one unit feeding of coking, can bring fuel gas system pipe network when steaming out greatly
Larger fluctuation, can cause the dry gas insufficient raw material of device for producing hydrogen simultaneously, in order to meet hydrogen feedstock demand, it has to supplement natural
Gas, coking fluid infusion activating QI, which adds energy consumption, also create unnecessary loss.Cause environmental pollution, affect chemical plant
Neighbouring surrounding, has a strong impact on individual physically and mentally healthy, and tail gas produced by cold Jiao is passed through to be emitted into by those skilled in the art
Torch pipe network reclaims, but is so also not reaching to the purpose saved energy and reduce the cost.Still have a certain amount of harmful gas to discharge, dirty
Dye air, burning simultaneously to waste substantial amounts of goods and materials, and it is imperative to utilize the process of tail gas.
Utility model content
This utility model, for the deficiencies in the prior art, proposes the cold burnt tail gas recycling system of a kind of coke drum.
The technical solution of the utility model is achieved in that
The cold burnt tail gas recycling system of a kind of coke drum, including coke drum, coke drum is by emptying tower separatory tank and water
Washing tower to connect, the other end of water scrubber is connected with compressor by fractional distillation tower top water-cooled.
Described emptying tower separatory tank lower end is connected with fluid recycling can.
Described fractional distillation tower top water-cooled lower end is connected with water recovery tank.
The beneficial effects of the utility model are:
The cold burnt tail gas recycling system of coke drum of the present utility model, the problem solving environmental pollution, simultaneously tail gas
Reclaim, the tail gas of discharge is incorporated to suction port of compressor, reached energy-saving and cost-reducing purpose, avoided the ripple of pipe network simultaneously
Dynamic, add hydrogen manufacturing insufficient raw material, avoid each device fluctuation being directed to use with fuel gas, it is to avoid abnormal conditions occur, and reduce simultaneously
The economic loss of company, alleviates ductwork pressure, reaches energy-saving and cost-reducing, ensure not discharge garbage simultaneously, be up to state standards.
Simple to operate, invest little, have high repayment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, coke drum；2, emptying tower separatory tank；3, water scrubber；4, fractional distillation tower top water-cooled；5, compressor；6, fluid
Recycling can；7, water recovery tank.
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Detailed description of the invention
Below in conjunction with this utility model embodiment, the technical solution of the utility model is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on this practicality
Embodiment in novel, the every other reality that those of ordinary skill in the art are obtained under not making creative work premise
Execute example, broadly fall into the scope of this utility model protection.
The cold burnt tail gas recycling system of a kind of coke drum, including coke drum 1, coke drum 1 by emptying tower separatory tank 2 with
Water scrubber 3 connects, and the other end of water scrubber 3 is connected with compressor 5 by fractional distillation tower top water-cooled 4.Described emptying tower separatory tank 2
Lower end is connected with fluid recycling can 6.Described fractional distillation tower top water-cooled 4 lower end is connected with water recovery tank 7.
Work process is, when coke drum 1 reacts the complete emptying tower separatory tank 2 that is passed through by tail gas, emptying tower separatory tank 2 can be by
The tail gas entered carries out gas-liquid separation, and liquid portion enters fluid recycling can 6, and gas is partially into water scrubber 3, enters water scrubber
Gas in 3 removes hydrogen sulfide therein and partial impurities after water scrubber 3 is washed, then is passed through fractional distillation tower top water-cooled 4, enters and divides
Evaporating cooled oil gas and the water of being separated into of gas of tower top water-cooled 4, water enters water recovery tank 7, and oil gas squeezes into compressor 5.Can be real
Existing tail gas again with.
Performance analysis: vent gas treatment is directly burnt, need to use fuel gas expense 2.74 yuan/cubic metre, needs 10 to stand per hour
Side's rice, 2.75*10*24=660, one day usage amount of output oil gas is 5 tons simultaneously.
Achieve in sum, the purpose of this utility model.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
