[0053] Piston compressor devices are widely used in technical fields such as petroleum and chemical industry. In some working conditions, it is necessary to first cool and then separate the liquid in the gas, and then buffer the high-speed airflow before it can enter the system. This requires the airflow to pass through the pre-cooler and the pre-separator in sequence; however, due to some work site restrictions, it is impossible to install the pre-cooler and the pre-separator at the same time, which may result in the lack of one of the processing steps when processing the gas, making it impossible to cool and separate the gas to be processed at the same time. At the same time, the device is not convenient for buffering the high-speed flowing gas, so that the high-speed flowing gas may cause impact on some structures and cause damage.

[0054] In view of this, an embodiment of the present application provides a cooling separator for a piston compressor to overcome at least one of the above-mentioned technical problems.

[0055] See also Figure 1 In the embodiment of the present application, the cooling separator of the piston compressor includes a first cylinder 1, a cooling assembly 2, and a separation assembly 3. The first cylinder 1 has a first accommodating chamber 11, and the first accommodating chamber 11 is used to accommodate the gas to be processed, so that the gas flows inside the first accommodating chamber 11, and the first accommodating chamber 11 has a connecting port 111; the cooling assembly 2 includes a accommodating portion 21 and a cooling portion 22, and the accommodating portion 21 is connected to the first cylinder 1 and sealed at the connecting port 111. Specifically, the accommodating portion 21 and the first cylinder 1 can be connected by bolts. When a fault occurs inside the device, it is convenient to open the accommodating portion 21 to expose the connecting port 111, so that the staff can inspect the inside of the device through the connecting port 111; wherein the cooling portion 22 is connected to the accommodating portion 21 and is located in the first accommodating chamber 11, and the cooling portion 22 is used to cool the gas entering the first cylinder 1, and the accommodating portion 21 is used to accommodate the cooling liquid; that is, since the accommodating portion 21 can accommodate the liquid used to cool the gas, and the cooling liquid in the accommodating portion 21 can enter the accommodating portion 21 located in the first cylinder The cooling part 22 inside the cavity 11, and the gas to be treated will also be passed into the first accommodating cavity 11, so that the cooling part 22 can cool the gas. Specifically, when the cooling liquid flows inside the cooling part 22, it will absorb the heat in the gas, so that the temperature of the gas is reduced to achieve the cooling effect; the separation component 3 is located in the first accommodating cavity 11 and is connected to the inner wall of the first cylinder 1, and the cooling part 22 is penetrated by the separation component 3. During the cooling process of the gas through the cooling part 22, the temperature of the gas is reduced and liquid will be precipitated. At the same time, the gas also continuously flows inside the first accommodating cavity 11. When flowing through the separation component 3, the separation component 3 will separate the gas into gas and liquid, so that the liquid can be adsorbed on the separation component 3, and the gas can continue to flow. Therefore, this structure concentrates the functions of cooling and separation on the same device, reduces the footprint of the device, and can cool and separate the gas to be treated at the same time.

[0056] See also Figure 1 In some embodiments, the cooling separator of the piston compressor also includes a buffer assembly 5, and the buffer assembly 5 includes a bumper plate 51.

Since the gas entering the first accommodating chamber 11 may have a higher flow rate, the bumper plate 51 arranged toward the air inlet can prevent the air flow from directly scouring the cooling part 22, which can play a buffering role for the gas.

[0057] Please continue reading Figure 1 In some embodiments, the accommodating portion 21 includes a tube sheet 214, a second cylinder 211, a water inlet pipe 212, and a water outlet pipe 213.

The plurality of cooling pipes 221 can be used to cool the gas entering the first accommodating chamber 11. The plurality of cooling pipes 221 are arranged through the separation assembly 3, so that the gas can be separated into gas and liquid through the separation assembly 3 at the same time during the cooling process. The cooling pipe 221 has a water inlet and a water outlet. The water inlet and the water outlet penetrate the tube sheet 214 and are connected to the second accommodating chamber 2111. Specifically, for the flow of the cooling liquid, please refer to Figure 8 The arrow direction in the figure is the flow direction of the cooling liquid.

Specifically, the gas entering the first accommodating chamber 11 will enter the third accommodating chamber 311 through the first opening 3111, flow in the third accommodating chamber 311, and then flow out of the third accommodating chamber 311 from the second opening 3112; the first end plate 32 is connected to the third cylinder 31 and covers part of the first opening 3111, and the first end plate 32 only covers part of the first opening 3111, so that the gas can still enter the third accommodating chamber 311 through the first opening 3111 and be cooled by the cooling pipe 221 passing through the third accommodating chamber 311; the second end plate 33 is connected to the third cylinder 31 The body 31 is connected to and covers a part of the second opening 3112, and the second end plate 33 also only covers a part of the second opening 3112, so that the gas can still be discharged from the inside of the third accommodating chamber 311 through the second opening 3112. The first end plate 32 and the second end plate 33 are connected to the two ends of the third cylinder 31, and are simultaneously connected to the inner wall of the first cylinder 1, which can be used to support and limit the third cylinder 31; the separation net 34 is located in the gap and connects the third cylinder 31 and the first cylinder 1 respectively. The outer wall of the third cylinder 31 has a plurality of perforations, which are respectively connected to the gap and the third accommodating chamber 311. Specifically, the gas entering the third accommodating chamber 311 can enter the inside of the gap from the plurality of perforations on the outer wall of the third cylinder 31, and thus be filtered by the separation net 34 arranged inside the gap, so as to filter out water droplets in the gas and separate particles with a diameter greater than 3 to 5 μm in the gas.

[0061] Please continue reading Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the first end plate 32 has a first flow hole 321 for gas to pass through, and the first flow hole 321 is respectively connected to the third accommodating chamber 311 and the first accommodating chamber 11, so that the gas entering the first accommodating chamber 11 can enter the third accommodating chamber 311 through the first flow hole 321; the second end plate 33 has a second flow hole 331 for gas to pass through, and the second flow hole 331 is respectively connected to the third accommodating chamber 311 and the first accommodating chamber 11, so that the gas entering the third accommodating chamber 311 can be discharged from the third accommodating chamber 311 through the second flow hole 331 and re-enter the first accommodating chamber 11.
