Abstract
Description
Technical Field
[0001] This invention relates to the field of gas compression processing technology, specifically to an energy-saving gas compressor and its usage method. Background Technology
[0002] A multi-stage bidirectional gas compressor is a device that achieves high-efficiency gas pressurization through multi-stage compression and bidirectional structural design. It is widely used in industrial fields that require high pressure ratio, large flow rate or special gas processing. Its principle is to gradually pressurize the gas in stages, and cool it down through an intercooler after each stage of compression, avoiding the high temperature and low efficiency problems caused by single-stage excessive pressure ratio.
[0003] During gas compression, a large amount of heat is generated due to energy conversion, causing the gas temperature to rise sharply. In traditional processes, each stage of compression is equipped with an independent intercooler, and each cooler needs to be connected to a separate refrigeration source. This results in repeated refrigeration and waste of cooling capacity. Furthermore, the condensate after heating lacks systematic regeneration treatment and is often directly discharged or cooled by natural cooling, which also wastes condensate and has limitations.
[0004] The reason for this problem is that after the high-temperature gas from the first stage compression is cooled by an independent cooler, the low-temperature condensate is heated. However, the heated condensate is not introduced into the cooling stage of the second stage compression; instead, it is directly discharged or only undergoes simple treatment. When the second stage compression produces a second set of high-temperature gas, another independent cooler is still required for cooling. This forces the chiller to operate at full load for both stages of cooling, resulting in wasted cooling capacity. Most processes directly discharge the heated condensate into the sewer, leading to low water resource utilization and significant waste in water-scarce areas or large-scale production. A few systems use open-air water tanks for natural cooling, but this is significantly affected by ambient temperature, and the cooled water temperature fluctuates greatly. This cannot meet the constant temperature requirements of precision compression processes, resulting in unstable second-stage compression efficiency and even pressure fluctuations in the gas storage stage. Therefore, we propose an energy-saving gas compressor and its usage method to solve the above problems. Summary of the Invention

The water injection assembly inside the cooling water tank 21, and the cooling assembly for cooling the high-temperature condensate inside the cooling water tank 21; through the action of the cold water component 23, the condensate is circulated inside the cooling water tank 21, and the flow direction of the condensate in the right space of the cooling water tank 21 is opposite to the flow direction of the gas discharged from the second pressure cylinder 12; the cooling component 24 is located below the cooling water tank 21, and the cooling component 24 is used to cool the condensate in the left space of the cooling water tank 21, so that the cooled condensate can effectively exchange heat and cool the gas discharged from the second pressure cylinder 12.

The second pneumatic cylinder 12 has cooling units 2 at its upper and lower ends for gas cooling. The cooling unit 2 includes a cooling water tank 21, a partition plate 22, a cooling water component 23, and a cooling component 24. A cooling water tank 21 is located on one side of the body 1; a partition plate 22 is located inside the body 1, dividing the interior of the cooling water tank 21 into two independent spaces, left and right. Gas discharged from the first pressure cylinder 11 enters the left space of the cooling water tank 21 through a specific channel, and gas discharged from the second pressure cylinder 12 enters the right space of the cooling water tank 21 through another specific channel.

[0036] Step 1: The gas enters the first pressure cylinder 11 and is compressed into high temperature and high pressure gas. The high temperature and high pressure gas is discharged from the first pressure cylinder 11 and enters the space on the left side of the cooling water tank 21. On the left side of the cooling water tank 21, the gas exchanges heat with the condensate inside the cold water component 23 and is cooled into low temperature and high pressure gas.
[0037] Step 2: The cooled low-temperature high-pressure gas enters the second pressure cylinder 12 and is compressed again into high-temperature high-pressure gas.

The condensate that has heated up after the second cooling process flows back into the chiller 231 for further cooling, and then is reinjected into the cooling water tank 21, forming a cycle.
[0040] In this embodiment, the gas enters the first pressure cylinder 11 and is compressed into high-temperature, high-pressure gas. The high-temperature, high-pressure gas then enters the left space of the cooling water tank 21, where it is cooled by the condensate inside the chiller 23. The cooled gas becomes low-temperature, high-pressure gas and then enters the second pressure cylinder 12, where it is compressed again into high-temperature, high-pressure gas. The gas then enters the right space of the cooling water tank 21. The condensate cools the gas inside the first pressure cylinder 11, causing its temperature to rise. The condensate is then injected into the cooling box 241. The chiller 231 injects condensate into the cooling box 241, lowering the original temperature of the condensate. This lowered condensate is then injected into the right space of the cooling water tank 21, allowing it to cool the gas discharged from the second pressure cylinder 12. The cooled, low-temperature, high-pressure gas enters the gas storage cylinder 13 for storage. The heated condensate is injected back into the chiller 231, and after cooling, it continues to enter the cooling water tank 21, completing the cycle.

10. A method of using an energy-saving gas compressor, wherein the energy-saving gas compressor according to claims 1-9 is characterized in that, Includes the following steps: Step 1: The gas enters the first pressure cylinder (11) and is compressed into high temperature and high pressure gas. The high temperature and high pressure gas is discharged from the first pressure cylinder (11) and enters the space on the left side of the cooling water tank (21). On the left side of the cooling water tank (21), the gas exchanges heat with the condensate inside the cold water component (23) and is cooled into low temperature and high pressure gas. Step 2: The cooled low-temperature high-pressure gas enters the second pressure cylinder (12) and is compressed again into high-temperature high-pressure gas. The high-temperature high-pressure gas after the second compression is discharged into the right space of the cooling water tank (21) to prepare for the second cooling. Step 3: The condensate water that has cooled the gas discharged from the first pressure cylinder (11) is injected into the cooling box (241) due to the heat absorption and the temperature rise. The chiller (231) injects new low-temperature condensate water into the cooling box (241) to lower the temperature of the original condensate water. The cooled condensate water is then injected back into the right space of the cooling water tank (21) to cool the high-temperature and high-pressure gas discharged from the second pressure cylinder (12). Step 4: In the space on the right side of the cooling water tank (21), the high-temperature and high-pressure gas is cooled down to low-temperature and high-pressure gas by the condensate, and then enters the gas storage cylinder (13) for storage. The condensate that has been heated after the second cooling is returned to the chiller (231) for cooling, and then re-injected into the cooling water tank (21) to form a cycle.
