Abstract

Coking plant low pressure loss gas recycling and processing device, including blower fan are the utility model is related to, collects conveying low pressure loss gas;Lye pump, for conveying desulfurization alkali lye;Cooler is evacuated, for cooling down the low pressure loss gas that pressurizes;The swirl injection absorber being connected with evacuating cooler, for removing loss sulfide in gas, particulate matter etc.;The ADSORPTION IN A FIXED BED tank being connected with swirl injection absorber, for removing VOCs in loss gas.The swirl injection absorber is single-stage, plural serial stage and/or parallel connection.

Description

A kind of coking plant low pressure loss gas recycling and processing device
The present utility model application requires entitled " a kind of high performance vulcanization hydrogen absorption plant ", and the applying date is 2016 9 Months 21 days, application number was 201610494578.6 invention, as in the utility model swirl injection absorber structure it is preferential Power.
Technical field
The utility model belongs to petrochemical industry and field of Environment Protection, is related to the recycling of coking plant low pressure loss gas and sets It is standby, suitable for low pressure loss gas removal process.Specifically, the utility model provides coking plant low pressure loss gas and returned Receive processing unit.
Background technology
Delayed coking is a kind of oil secondary operation technology, is one of the main method of current world's residual oil deep processing. So-called delay refers to the boiler tube that residual oil is flowed through to heating furnace with high flow velocity, is heated to react required temperature, in reaction boiler tube Inside not green coke, and delaying to pyrogenetic reaction is carried out again into coke drum, there is a delayed-action, therefore referred to as Delayed Coking Technology.
Delayed coking can improve the yield and decarburization efficiency of light oil, operate that serialization, treating capacity be big, flexibility with it By force, the characteristics of investment cost is low is always the main path of world's heavy oil lighting, and the most important processing of heavy oil hand in China Section.Warm sludge oil carries out pyrogenetic reaction in coke drum, and the lighter products of generation out enter fractionating column from top, fractionate out richness Gas, raw gasoline, diesel oil and heavy distillate.
Delayed coking is a kind of continuous production, the method for intermittent operation, typically at least two coke drums, and one online raw Another is devoked when burnt.Delayed coking unit in Jiao, cold-cut water system, decoking process is unlimited operation due to cutting, Arrange loss outside decoking waste gas, burnt pond air storage, coke powder disperse, in petroleum coke volatile matter volatilization, cause coking plant to produce Macroscopic dust pollution thing, and the air peculiar smell that smell can be perceived substantially, are polluted, serious threat behaviour to environment Make the health of personnel.
The method and apparatus for coking decoking exhaust-gas treatment domestic at present are seldom, and many treating method and apparatus are simultaneously paid no attention to Think.Such as patent 201320049476.5, a kind of coking decoking emission-control equipment is described, but the device is related to multiple equipment, And floor space is larger;Patent 201510654944.5 is related to petrochemical refining's coking plant gas sampling governing system device, The utility model equipment is more, and method is complicated;It is net that patent 201520780147.7 introduces a kind of petrochemical refining's coking plant waste gas Makeup is put, and equally exists above mentioned problem.
Utility model content
In order to overcome the shortcomings of above-mentioned existing method and device, the utility model provides coking plant low pressure loss gas Recovery and treatment method and device.Loss gas reclaimed water, sulfur-bearing thing, VOCs and other malodor components can be removed, reduce fuel gas and dust Content, gas total sulfur content is less than 1mg/m after making purification3, VOCs is less than 60mg/m3, dust is less than 20mg/m3
A kind of coking plant low pressure loss body recycling and processing device, the device include:
Blower fan 1, collect conveying low pressure loss gas;Lye pump 2, for conveying desulfurization alkali lye;Cooler 3 is evacuated, is used for Cooling pressurization low pressure loss gas;The swirl injection absorber 4 being connected with evacuating cooler, vulcanizes for removing in loss gas Thing, particulate matter etc.;The ADSORPTION IN A FIXED BED tank 5 being connected with swirl injection absorber, for removing VOCs in loss gas.
Preferably, the evacuation cooler utilizes high pressure coke cooling water caused by original coke cooling water pump in coking plant, carries out Pumping supercharging.
Preferably, the desulfurization absorption efficiency of the swirl injection absorber is more than 99%.
