Description
Technical field
The utility model relates to a kind of propylene compressor driving dry gas seals gas gas handling system, belongs to technical field of chemical industry.
Background technique
When propylene compressor runs, dry gas seals is divided into one-level hermetic seal and secondary seal; one-level plays primary seal effect; need pressure very high; generally use machine set outlet gas; some also will enter unit, and secondary mainly prevents primary seal bad, may play second protection effect; prevent blanket gas from polluting the effect of seal face in addition, generally use nitrogen.But when propylene compressor is started shooting, generally all still adopt nitrogen (needing certain pressure) as sealing gas, so still nitrogen can be caused to enter propylene system, thus build-up of pressure is excessive, needs emptying, will large losses propylene gas.
Model utility content
For existing problem, the purpose of this utility model is to provide a kind of safe, propylene compressor dry gas seals gas gas handling system of saving propylene gas.
To achieve these goals, the technical solution of the utility model is: a kind of propylene compressor driving dry gas seals gas gas handling system, comprise propylene compressor driving dry gas seals gas suction tude and propylene compressor driving dry gas seals air intake valve, it is characterized in that: also comprise propylene separation device, propylene liquid pump and propylene vaporizer, the propylene liquid outlet of described propylene separation device bottom is connected with propylene liquid pump by pipeline, described propylene liquid delivery side of pump is connected with the cold side import of propene carburator, the hot side outlet of described propylene vaporizer is connected with propylene compressor driving dry gas seals air intake valve by pipeline, the hot side-entrance of described propylene vaporizer is connected with saturated steam pipe.,
Adopt technique scheme, the propylene liguid in propylene steam is separated by propylene separation device, is separated the propylene steam obtained and compresses or other places to go for propylene gas.Propylene liguid through propylene liquid pump pressurization after enter propylene vaporizer, then in propylene vaporizer by heat vaporized for propylene liguid be propylene steam, blanket gas when driving for propylene compressor.After adopting the method, propylene separation device can be utilized to be separated the propylene liguid obtained on the one hand, nitrogen can be avoided again to enter in propylene system simultaneously, thus avoid gas emptying, avoid the loss causing propylene.
In technique scheme: be provided with wire packing in described propylene separation device, the below of the wire packing of described propylene separation device is provided with propylene gas import, and the top of described propylene separation device and bottom are respectively equipped with propylene gas outlet and propylene liquid outlet.
In technique scheme: also comprise propylene storage tank, the cold side import of described propylene vaporizer is also connected with propylene storage tank by pipeline.The liquid propene be separated when propylene separation device so very little, or when propylene separation device is stopped using.Can by the propylene liquid in propylene storage tank.
The beneficial effects of the utility model are: the propylene liguid that the utility model adopts propylene separation device to separate, and after the pressurization of propylene liquid pump, re-vaporize the dry gas seals gas when propylene gas obtained is started shooting as propylene compressor, safety, can avoid emptying, reduce the waste of propylene, cost-saving.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Embodiment 1
As shown in Figure 1, propylene compressor driving dry gas seals gas gas handling system of the present utility model is made up of parts such as propylene compressor driving dry gas seals gas suction tude 1, propylene compressor driving dry gas seals air intake valve 2, propylene separation device 3, propylene liquid pump 4, propylene vaporizer 5, propylene storage tanks 7.
The structure of propylene compressor is prior art, and its dry gas seals system is also prior art, does not repeat at this.Propylene compressor driving dry gas seals air intake valve 2 arranges in propylene compressor driving dry gas seals gas suction tude 1, adopts external propylene gas to seal at propylene compressor when starting shooting, and after driving, then switches to machine set outlet gas and seals.
Be provided with wire packing 32 in propylene separation device 3, the below of the wire packing 32 of propylene separation device 3 is provided with propylene gas import 33, and the top of propylene separation device 3 and bottom are respectively equipped with propylene gas outlet 34 and propylene liquid outlet 31.Propylene separation device 3 is for the gas-liquid separation of propylene gas.
The propylene liquid outlet 31 of propylene separation device 3 bottom is connected with propylene liquid pump 4 by pipeline, the outlet of propylene liquid pump 4 is connected with the cold side import (import of propylene liquid) of propene carburator 5, the hot side outlet of propylene vaporizer 5 out be propylene gas, be connected with propylene compressor driving dry gas seals air intake valve 2 by pipeline, the hot side-entrance of propylene vaporizer 5 is connected with saturated steam pipe 6, the cold side outlet port of propylene vaporizer 5 out be steam condensate.
The cold side import of propylene vaporizer 5 is also connected with propylene storage tank 7 by pipeline.Propylene storage tank 7 is as subsequent use, and the liquid be separated when propylene separation device 3 is few, or adopts the propylene liquid in propylene storage tank 7 when propylene separation device 3 is stopped using.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
