Description

Technical Field

[0001] The utility model relates to the technical field of propylene compressors, and particularly relates to a rapid evaporation device for propylene liquid of a propylene compressor. Background Technique

[0002] A propylene compressor is a mechanical device specifically used for compressing propylene gas. It has a wide range of applications in industries such as chemical engineering, petroleum, and natural gas. It is mainly used to increase the pressure of propylene gas for storage, transportation, and further chemical reactions. Propylene is an important chemical raw material commonly used in the production of plastics, synthetic fibers, resins, and other products. In these production processes, propylene needs to undergo a polymerization reaction under high pressure, which requires the use of a propylene compressor to provide the necessary pressure. The working principle of a propylene compressor is similar to that of other types of compressors, which is to mechanically reduce the volume of the gas to increase its pressure. According to different working methods, propylene compressors can be divided into various types such as reciprocating, centrifugal, and screw types.

[0003] During the start-up and operation of a propylene compressor, liquid accumulation often occurs in the first-stage inlet separator. If the liquid level in the first-stage inlet separator is too high, there is a risk of liquid carry-over in the compressor, which may damage the compressor. The propylene condensate pump at the bottom of the first-stage inlet separator is a canned motor pump, and frequent start-stop is not beneficial to the canned motor pump. Frequent start-stop of the canned motor pump will cause the motor to be heated and cooled multiple times in a short period, which is likely to cause the motor to overheat and reduce the service life of the motor. At the same time, each time the pump is started, the internal parts of the pump will experience an impact, and frequent start-stop will accelerate the wear of these parts, resulting in a decline in the pump's performance. Moreover, each start requires additional energy consumption, and frequent start-stop will increase energy consumption. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rapid evaporation device for propylene liquid of a propylene compressor to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rapid evaporation device for propylene liquid of a propylene compressor, including a chassis, one side of the chassis is fixed with a bottom plate, and further includes:

[0006] An acrylic compressor body is provided on the top of the chassis. An inlet section and a second-stage inlet are respectively provided on the inner wall of the acrylic compressor body. A recovery mechanism for evaporating excess acrylic liquid is provided between the inlet section and the second-stage inlet. The recovery mechanism includes an exhaust pipe connected to the second-stage inlet. One end of the exhaust pipe is respectively connected to a first gas transmission pipe and a second gas transmission pipe. One end of the first gas transmission pipe is connected to a vertical pipe, and the vertical pipe is connected to the inner wall of the inlet section. A limiting plate is fixed on the inner wall of the inlet section. A clean gas pipe is connected to the inner wall of the inlet section. Support mechanisms are provided at the bottoms of the first gas transmission pipe and the second gas transmission pipe.

[0007] Preferably, solenoid valves are provided on the inner walls of the exhaust pipe, the vertical pipe, and the clean gas pipe.

[0008] Preferably, the support mechanism includes an upper clamping ring and a lower clamping ring provided on the outer side of the first gas transmission pipe. Heat insulation plates are provided on the inner sides of the upper clamping ring and the lower clamping ring.

[0009] Preferably, connection blocks are fixed on the outer sides of the upper clamping ring and the lower clamping ring. A first bolt is threadedly connected to the inner wall of the connection block.

[0010] Preferably, a bottom block is fixed to the bottom of the lower clamping ring. A stud is fixed to the bottom of the bottom block. A threaded seat is threadedly connected to the outer side of the stud. A base is fixed to the bottom of the threaded seat.

[0011] Preferably, threaded holes are provided in the inner walls of the base and the bottom plate. A second bolt is threadedly connected to the inner wall of the threaded hole.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By setting the recovery mechanism, the present utility model can lead high-temperature acrylic gas to the inlet separator of the first stage before the vent valve at the second-stage outlet of the acrylic compressor to accelerate the evaporation of acrylic liquid, thereby reducing the start-stop frequency of the acrylic condensate pump, making the acrylic condensate pump not easily damaged. At the same time, the risk of the acrylic compressor carrying liquid is also reduced, avoiding the problem that the frequent start-stop of the acrylic condensate pump causes the motor to be heated and cooled multiple times in a short time, which is likely to cause the motor to overheat, improving the service life of the motor, improving the performance of the pump, and reducing energy consumption.
