Description

Technical Field

[0001] The utility model relates to the technical field of gas processing, in particular to an exhaust cooling structure of a gas-driven booster pump. Background Art

[0002] In production and life, the use of special gases usually needs to be prepared first and then stored in specific tanks. During this process, the prepared gas needs to be filtered, dried, pressurized, etc., so that the gas stored in the specific tank is a high-pressure gas that meets the requirements, and it also facilitates the loading of the gas into the specific tank.

Although the above structure can meet the use requirements of pressurizing gas, the driving exhaust gas discharged from the exhaust hole is directly discharged to the outside when it is used, resulting in a waste of resources. In addition, since the volume of the gas will be compressed during the pressurization process, the gas temperature will increase, and the high-pressure gas subsequently discharged from the booster pump needs to be cooled by an additional heat exchanger, which makes the overall pipeline structure complicated and increases the cost of gas preparation.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 3 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0022] Figure 1 This is a structural diagram of an embodiment of an air-driven booster pump exhaust cooling structure of the utility model. Figure 1 As shown, the gas-driven booster pump exhaust cooling structure provided in this embodiment includes a heat exchange tube 1, through which the driving exhaust gas of the gas-driven booster pump 2 is utilized, thereby realizing cooling of the high-pressure and high-temperature gas obtained by the operation of the gas-driven booster pump 2, meeting the requirements of energy conservation and environmental protection and reducing the cost of gas preparation.

[0023] Specifically, the heat exchange tube 1 is arranged at the driving gas exhaust port 21 of the gas-driven booster pump 2, so that the driving exhaust gas discharged from the driver exhaust port when the gas-driven booster pump 2 is working can be blown to the heat exchange tube 1, so as to realize the heat exchange operation with the heat exchange tube 1, and provide conditions for the subsequent cooling treatment of the gas flowing through the heat exchange tube 1. At this time, the two ends of the heat exchange tube 1 are respectively connected to the high-pressure gas outlet 22 of the gas-driven booster pump 2 and the external transmission pipeline, that is, when the gas-driven booster pump 2 is working, the high-pressure gas compressed by the gas-driven booster pump 2 will increase the gas temperature due to the volume compression, so that the high-pressure gas discharged from the high-pressure gas outlet 22 of the gas-driven booster pump 2 is high-pressure and high-temperature gas. At present, it is usually adopted to set up another heat exchanger in the subsequent transportation pipeline of the high-pressure and high-temperature gas, that is, to use other resources to cool the high-pressure and high-temperature gas. Although it can meet the cooling demand, it is necessary to invest additional resources for cooling, which will cause waste of resources and increase the cost of gas preparation. In this embodiment, the heat exchange tube 1 is connected between the high-pressure outlet 22 of the gas-driven booster pump 2 and the external transportation pipeline, so that the high-pressure and high-temperature gas compressed by the gas-driven booster pump 2 can be discharged from the high-pressure outlet 22 and then flow into the external transportation pipeline through the heat exchange tube 1. At this time, since the heat exchange tube 1 is heat exchanged by the driving exhaust gas discharged from the exhaust port of the driver, the high-pressure and high-temperature gas flowing through the heat exchange tube 1 is also cooled, which can not only meet the reuse of the driving exhaust gas of the gas-driven booster pump 2 and avoid waste of resources, but also meet the cooling demand for high-pressure and high-temperature gas, and there is no need to add additional equipment such as a heat exchanger, which simplifies the overall pipeline structure and reduces the cost of gas preparation.

[0024] Figure 2 This is a structural diagram of a heat exchange tube in a preferred embodiment of the utility model. Figure 1 and Figure 2 As shown, the heat exchange tube 1 is a spiral tube structure, that is, the heat exchange tube 1 is a tubular structure formed by winding a straight tube along a spiral line, so that the lateral space can be fully utilized within the same length layout space, so that the heat exchange area of ​​the heat exchange tube 1 is larger, that is, the heat exchange tube 1 can arrange more heat exchange surfaces at the driving gas exhaust port 21 of the gas-driven booster pump 2, thereby improving the heat exchange efficiency and the heat exchange effect. In addition, the spiral extension layout direction of the heat exchange tube 1 and the exhaust direction of the driving gas exhaust port 21 are set to be consistent, so that the driving exhaust gas can be blown out from the driving gas exhaust port 21 along the layout length layout direction of the heat exchange tube 1, which maximizes the extension of the heat exchange time between the driving exhaust gas and the heat exchange tube 1, realizes the full utilization of the driving exhaust gas, and further improves the heat exchange effect.

[0025] More specifically, a muffler 3 is installed on the driving gas exhaust port 21 of the air-driven booster pump 2, so that the driving exhaust gas blown out from the driving gas exhaust port 21 will be silenced by the muffler 3 when discharged, thereby reducing working noise and improving the comfort of the working environment.

[0026] More specifically, after the muffler 3 is installed on the driving gas exhaust port 21 of the gas-driven booster pump 2, the heat exchange tube 1 arranged at the driving gas exhaust port 21 is wound around the outside of the muffler 3. That is, when the driving exhaust gas is discharged through the muffler 3, the heat exchange tube 1 can exchange heat with the driving exhaust gas discharged from the muffler 3, which can not only meet the use requirement of reducing working noise, but also realize the reuse of the driving exhaust gas, thereby improving the use comfort and reducing the gas preparation cost.

[0027] More specifically, quick-connect connectors 4 are provided at both ends of the heat exchange tube 1, that is, each end of the heat exchange tube 1 is provided with a quick-connect connector 4. At this time, when the heat exchange tube 1 is installed between the high-pressure air outlet 22 and the external delivery pipeline, the quick-connect connectors 4 at both ends can be respectively connected to the high-pressure air outlet 22 of the air-driven booster pump 2 and the external delivery pipeline, which facilitates the disassembly and assembly of the heat exchange tube 1, improves the assembly effect, and provides convenience for the subsequent inspection and maintenance of the pipeline, and the structural design is more reasonable.

[0028] More specifically, the quick-connect joints 4 provided at both ends of the heat exchange tube 1 are screw-in conical joints, which can realize the rotational installation of the quick-connect joints, making it more convenient to disassemble and assemble. Moreover, the screw-in conical joints are existing products on the market, which can be directly purchased and used without additional processing, making production and manufacturing more convenient.

[0029] Figure 3 This is a structural diagram of another heat exchange tube of a preferred embodiment of the utility model. Figure 1 and Figure 3 As shown, this embodiment also provides a heat exchange tube 1 structure in another state, in which the heat exchange tube 1 is a reciprocating folding structure, that is, the heat exchange tube 1 adopts a reciprocating folding method to fully utilize the lateral space within the same length arrangement space, so that the heat exchange area of ​​the heat exchange tube 1 is larger, so that the heat exchange tube 1 can arrange more heat exchange surfaces at the driving gas exhaust port 21 of the gas-driven booster pump 2, which can also improve the heat exchange efficiency and ensure the heat exchange effect. It is worth pointing out that the folding direction of the heat exchange tube 1 arranged in a reciprocating folding structure is consistent with the exhaust direction of the driving gas exhaust port 21, and the arrangement direction of the heat exchange tube 1 can also be consistent with the exhaust direction of the driving exhaust gas from the driving gas exhaust port 21, thereby maximizing the contact time between the driving exhaust gas and the heat exchange tube 1, realizing full utilization of the driving exhaust gas, and also improving the heat exchange effect.

[0030] More specifically, if the heat exchange tube 1 has a repeatedly folded structure, several groups of heat exchange tubes 1 arranged in a reciprocating folding structure may be provided. At this time, several groups of heat exchange tubes 1 are distributed in a ring array, so that several groups of heat exchange tubes 1 can form a circle, and several groups of heat exchange tubes 1 are arranged on the outside of the driving gas exhaust port 21, so that the heat exchange tubes 1 arranged on the outside of the driving gas exhaust port 21 can not only surround the driving gas exhaust port 21, but also maintain their own reciprocating folding structure, thereby further increasing the heat exchange area in the unit space, further improving the heat exchange efficiency, achieving full utilization of the driving exhaust gas, and having a better cooling effect on the high-pressure and high-temperature gas.

[0031] More specifically, when several groups of heat exchange tubes 1 are provided, adjacent groups of heat exchange tubes 1 are connected in an end-to-end manner, that is, several groups of heat exchange tubes 1 are connected in series, so that the high-pressure and high-temperature gas can repeatedly flow back and forth at the driving gas exhaust port 21 when flowing through the heat exchange tubes 1, and the cooling time is longer and the cooling effect is better.

[0032] More specifically, in order to improve the gas processing efficiency, several gas-driven booster pumps 2 can be provided. At this time, the high-pressure gas outlets 22 of several gas-driven booster pumps 2 are connected in parallel and then connected in series with one end of the heat exchange tube 1, so that multiple gas-driven booster pumps 2 can work simultaneously, and more high-pressure and high-temperature gas can be generated, and the processing efficiency is higher. At the same time, the heat exchange tube 1 is set at the driving gas exhaust port 21 of a gas-driven booster pump 2, so that the high-pressure and high-temperature gas obtained by the operation of multiple gas-driven booster pumps 2 can enter the heat exchange tube 1 and be cooled through the heat exchange tube 1, which also meets the use requirements.

[0033] The gas-driven booster pump exhaust cooling structure provided in the present embodiment includes a heat exchange tube 1; by connecting the two ends of the heat exchange tube 1 with the high-pressure outlet 22 of the gas-driven booster pump 2 and the external transmission pipeline respectively, the high-pressure and high-temperature gas compressed by the gas-driven booster pump 2 can flow into the heat exchange tube 1 after being discharged from the high-pressure outlet 22, and the heat exchange tube 1 is arranged at the driving gas exhaust port 21 of the gas-driven booster pump 2. When the high-pressure and high-temperature gas flows through the heat exchange tube 1, the driving exhaust gas used for the operation of the gas-driven booster pump 2 can be blown toward the heat exchange tube 1 after being discharged from the driving gas exhaust port 21, and the high-pressure and high-temperature gas flowing through the heat exchange tube 1 is cooled. This can not only realize the reuse of the driving exhaust gas of the gas-driven booster pump 2 and avoid the waste of resources, but also avoid the need to set up an additional heat exchanger while meeting the need to cool the gas, thereby simplifying the overall pipeline structure and reducing the gas preparation cost.
