The utility model discloses the technical problem who easily causes the compressor to damage has mainly been solved when liquid is too much in the buffer tank of current suction port of compressor. The utility model discloses at the other lighter hydrocarbons collection tank that sets up of suction port of compressor buffer tank, and make the lighter hydrocarbons collection tank be located the following of suction port of compressor buffer tank, flow automatically to the lighter hydrocarbons collection tank in through the lime set of liquid level difference in with the suction port of compressor buffer tank, after full jar of lighter hydrocarbons collection tank, height after the compression of rethread compressor is calmed the anger for the pressure boost of lighter hydrocarbons collection tank, it is direct with in liquefaction atmospheric pressure to the cryogen flash tank in the lighter hydrocarbons collection tank, use as the raw materials once more, the damage compressor had both been avoided, the power consumption has been saved again, and the production cost is greatly reduced, maneuverability has been improved again.
Description
Technical field
The utility model belongs to sulfuric acid process alkylated reaction equipment technical field, is specifically related to a kind of compressor and coagulates
Liquid recovery system.
Background technology
In sulfuric acid process alkylation process, the gas phase (mainly iso-butane) from flash drum overhead enters pressure
Contracting machine inlet buffer, after the lime set that removing gas phase is carried, compresses supercharging by refrigeration compressor, then passes through
After air cooler is condensed into liquid phase, enter cryogen surge tank.Cryogen delivers to gasoline upgrading reactor by cryogenic fluid pump
Participate in reaction.Liquefied gas in existing refrigeration compressor inlet buffer is to be recycled to tank field by pump,
Because entrance back pressure is the lowest, pump is difficult to start, and is easily generated cavitation, it is impossible to reclaim liquefied gas in time to tank
District.When suction port of compressor, surge tank liquid level of liquefied gas is too high, can affect the work of refrigeration compressor, work as compression
Reclaim not in time when liquid in machine inlet buffer is too much, compressor will be damaged, and cause stopping work.
Summary of the invention
The purpose of this utility model is to solve to easily cause compression when existing suction port of compressor buffering pot liquid is too much
The technical problem that machine damages, it is provided that a kind of compressor lime set recovery system.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of compressor lime set recovery system, delays including cryogen flash tank, lighter hydrocarbons collecting tank, suction port of compressor
Rush tank, compressor, air cooler and cryogen surge tank, the gaseous phase outlet of described cryogen flash tank by pipeline with
The gas phase entrance of suction port of compressor surge tank connects, and the liquid phase entrance of cryogen flash tank is delayed with cryogen by pipeline
The liquid-phase outlet rushing tank connects, and the lime set of cryogen flash tank reclaims entrance by setting valvular pipeline and lighter hydrocarbons
The lime set of collecting tank reclaims outlet and connects, after cryogen is delivered to by the cryogen outlet connection cryogenic fluid pump of cryogen flash tank
Continuous reaction process, the liquid phase entrance of cryogen surge tank is connected with the liquid-phase outlet of air cooler by pipeline, lighter hydrocarbons
The pumping entrance of collecting tank is connected by setting valvular pipeline with the outlet of compressor, the gas of lighter hydrocarbons collecting tank
The entrance that balances each other is connected with the gaseous phase outlet of suction port of compressor surge tank by setting valvular pipeline, and lighter hydrocarbons are received
The lime set of collection tank reclaims entrance by setting the condensate outlet of valvular pipeline and suction port of compressor surge tank even
Connecing, and make lighter hydrocarbons collecting tank be positioned at below the surge tank of suction port of compressor, the gaseous phase outlet of surge tank is by setting
Valvular pipeline is connected with the gas phase suction inlet of compressor, and the outlet of compressor is by setting valvular pipeline
It is connected with the entrance of air cooler.
The utility model uses above technical scheme, arranges lighter hydrocarbons collecting tank by the surge tank of suction port of compressor,
And make lighter hydrocarbons collecting tank be positioned at below the surge tank of suction port of compressor, by liquid level difference, suction port of compressor is buffered
Lime set in tank, from flowing in lighter hydrocarbons collecting tank, after lighter hydrocarbons collecting tank canful, then passes through compressor compresses
After high pressure gas to lighter hydrocarbons collecting tank supercharging, directly the liquefied gas in lighter hydrocarbons collecting tank is depressed into cryogen flash tank
In, again use as raw material, both avoided damage compressor, saved again electricity consumption, made production cost big
Amplitude declines, and improves again operability.Therefore, compared with background technology, the utility model has saving
Electricity consumption and the advantage reducing production cost.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
