Abstract
The utility model provides a propylene recovery system device capable of avoiding intense vibration, comprising a first compressor, a second compressor, a first valve, a second valve, a first check valve, a second check valve and a propylene condenser, wherein the first compressor is connected in series with the first valve and the first check valve and subsequently connected with the propylene condenser; and the second compressor is connected in series with the second valve and the second check valve and subsequently connected with the propylene condenser. A first damping tank is connected in series between the first valve and the first check valve; and a second damping tank is connected in series between the second valve and the second check valve. In the propylene recovery system device, by arranging outlets additionally, the vibration degree of a compressor outlet pipeline of each damping tank is greatly reduced; only slight vibration occurs; the normal production and the normal running are facilitated; and the normal safety production can be guaranteed to a certain degree.
Description
Technical field
The utility model relates to Propylene Recovery System technical field in the polypropylene production process, is specifically related to a kind of Propylene Recovery System device that can avoid sharp pounding.
Background technology
At present; Propylene reclaims and mostly is to use propylene compressor recovery part gas-phase propene in polypropylene production process; But in view of this compressor delivery pressure height, and the inflammable and explosive unsafe factor of medium, be in for a long time in the intensive vibrations for outlet conduit; Pipeline and compressor plant fixed part are loosening often, have unsafe factor.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of Propylene Recovery System device that can avoid sharp pounding is provided.
Its technical scheme is: comprise first compressor, second compressor, first valve, second valve, first vacuum breaker, second vacuum breaker and propylene condenser; First compressor is connected in series with first valve and first vacuum breaker and then is connected with propylene condenser, and second compressor is connected in series with second valve and second vacuum breaker and then is connected with propylene condenser.Also be in series with first surge tank between said first valve and first vacuum breaker; Also be in series with second surge tank between said second valve and second vacuum breaker.
The utility model has very big minimizing through the vibrations degree of the surge tank compressor outlet pipeline of increasing export, and has only slight vibrations, helps the ordinary production operation, and normal safety in production is had certain guarantee.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1; A kind of Propylene Recovery System device that can avoid sharp pounding; Comprise first compressor 1, second compressor 5, first valve 2, second valve 6, first vacuum breaker 4, second vacuum breaker 8 and propylene condenser 9; First compressor 1 is connected in series with first valve 2 and first vacuum breaker 4 and then is connected with propylene condenser 9, and second compressor 5 is connected in series with second valve 6 and second vacuum breaker 8 and then is connected with propylene condenser 9.Also be in series with first surge tank 3 between said first valve 2 and first vacuum breaker 4; Also be in series with second surge tank 7 between said second valve 6 and second vacuum breaker 8.
Vibrations degree through the surge tank compressor outlet pipeline of increasing export has very big minimizing, has only slight vibrations, helps the ordinary production operation, and normal safety in production is had certain guarantee.
