Description
Technical field
The invention belongs to waste oil Petrochemical Enterprises refinery gas recovery technology fields, relate generally to a kind of waste oil of achievable isolation
Water seal arrangement before recycling alembic.
Background technology
Clean manufacturing is the energy saving and environmentally friendly important topic of petrochemical industry.For a long time, domestic and international oil plant, petrochemical industry
The oil-processing enterprises such as factory, pitch factory, lubricating oil plant depressurize distilling apparatus, fractionating device in crude refining process
The refinery gas that tower top generates（On-condensible gas）The method of generally use high altitude discharge had not only caused a part of energy waste in this way, but also
Surrounding area air environment is caused seriously to pollute.
At present, oil plant, petrochemical plant are vacuumized in production run using water vapour mostly or machinery is taken out very narrow two kinds and subtracted
Pressure method.Former approach is that Top of Vacuum Tower is distillated the condensed device of gas and level-one vacuum ejector, enters back into intermediate condensation
Device, and enter post-condenser through second steam vacuum ejector, then the refinery gas at the top of post-condenser is discharged into air or
Person directly burns.Later approach is then that Top of Vacuum Tower is distillated gas to enter condenser, directly with vacuum pump by its napex
Refinery gas extraction be discharged into air or directly burn.It is measured according to assay, content is usually contained in Top of Vacuum Tower tail gas
The light petroleum hydro carbons very high, calorific value is larger discharges it into air or burning is a kind of energy waste in the air, directly arranges
Environmental pollution can be caused by putting, very unfavorable with environmental protection to increasing economic efficiency.
A kind of refinery atmospheric storage-tank waste gas is disclosed in the sinopec patent document of Publication No. CN204237054U
Retracting device, the mode using refinery gas recycling are to use to deposit tank and use or sell as fuel energy after reprocessing,
It is required that full-blown equipment, system complex, operational administrative are of high cost.It at present, can be by oil refining enterprise without particularly effective method
Refinery gas in production process is used safely directly as internal power source, the reason is that refinery gas is in the feelings without safe handling
Directly using can there are explosive accidents to occur under condition.Due to refinery gas be oil refining generation by-product, limits throughput and continue
The features such as property is not strong, is not suitable as main energy sources.It is difficult to control, is easily mixed into air and sets off an explosion danger.It is returned in refinery gas
It receives in the scheme directly utilized, only relies on setting valve group and alarm system still cannot ensure that refinery gas is completely safely made
With.Existing valve block structure is complicated, uses for a long time, the corrosive gas in ventilation pipe is bonded in the moving component in valve group
On, cause the stuck of valve group or failure.
Invention content
The present invention seeks to be directed to the recycling of current refinery gas directly using it is difficult the problem of, provide it is a kind of can be achieved every
From waste oil recycling alembic before water seal arrangement, it is simple in structure, can substitute using valve group and alarm.
The technical scheme is that：
Water seal arrangement before a kind of waste oil recycling alembic of achievable isolation, including water tank, air inlet pipe and air outlet pipe,
The water tank includes the intake chamber and seal groove that are separated by vertical baffle, and the upper end of intake chamber is equipped with water inlet, seal groove
Upper end be equipped with sealing plate, the upper end of vertical baffle is fixedly connected with sealing plate, slot of the lower face away from water tank of vertical baffle
The height at bottom is H1；Sealing plate is vertically coated with air inlet pipe fitting and outlet pipe fitting respectively, the lower face of air inlet pipe fitting away from
The height of the slot bottom of water tank is H2, and the height of slot bottom of the lower face away from water tank of outlet pipe fitting is H3, H1< H2< H3；
The upper end of air inlet pipe fitting and the lower end of air inlet pipe connect, and the upper end of outlet pipe fitting and the lower end of air outlet pipe connect.
Preferably, the outside of the side wall of the intake chamber is equipped with the drainpipe connected with intake chamber, and drainpipe is equipped with row
Conduit control valve.
Preferably, the height of slot bottom of the drainpipe away from water tank is H4, H1< H4< H2.
Preferably, the upper end of the air inlet pipe fitting is equipped with air inlet pipe coupling flange, and the lower end of air inlet pipe is equipped with air inlet
Pipe flange, air inlet pipe coupling flange are bolted with air inlet pipe flange；The upper end of outlet pipe fitting is equipped with outlet pipe fitting
Flange, the lower end of air outlet pipe are equipped with outlet pipe flange, and outlet pipe coupling flange is bolted with outlet pipe flange.
Preferably, the first gasket, outlet pipe fitting are equipped between the air inlet pipe coupling flange and air inlet pipe flange
The second gasket is equipped between flange and outlet pipe flange.
The beneficial effects of the invention are as follows：
Water seal arrangement realizes air inlet pipe and outlet by water seal before the waste oil recycling alembic of the achievable isolation of the application
The connection of pipe, when pressure, which occurs, in air inlet pipe to be increased suddenly, high pressure gas compressing water is moved from seal groove to intake chamber, so as to real
Now to being mutated the anticyclonic pressure stability for liquidating, effectively keeping air outlet pipe；It, will when the equipment of air outlet pipe rear end needs maintenance
Water level promoting in water tank is to the lower end for flooding admitting pipe joint, you can realizes the sealing of pipeline, reduces shutting down for equipment.This
Invention avoids valve group and uses internal adhesion for a long time without especially setting control valve, while can substitute traditional valve group
The problem of, it is simple in structure, it is capable of the normal use of security control refinery gas, it is ensured that pipeline safety, convenient operating maintenance are very suitable
Close promotion and implementation.
