Description

Technical Field

[0001] This utility model relates to the field of air compressors, and specifically to an air compressor heat energy recovery and utilization device. Background Technology

[0002] When an air compressor is running, its exhaust temperature can reach over 110℃. It then needs to pass through an aftercooler using circulating cooling water to cool and remove moisture from the compressed air. This process requires a large amount of cooling water, and the heat is not recovered, resulting in both water consumption and wasted energy. Meanwhile, in factory air-conditioned workshops, during winter when temperatures are low, air conditioning units need to circulate hot water to maintain the required process temperatures, thus creating a heat energy demand for the air conditioning units.

[0003] Based on the above, this utility model proposes an air compressor heat energy recovery and utilization device. Utility Model Content

[0004] The main objective of this invention is to provide an air compressor heat energy recovery and utilization device to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air compressor heat energy recovery and utilization device, comprising a shell-and-tube heat exchanger, a spinning air conditioning hot water return pipeline, and a spinning air conditioning hot water supply pipeline. One end of the shell-and-tube heat exchanger is provided with an inlet pipeline and an outlet pipeline. One end of the inlet pipeline is provided with a first pipeline, and a circulation pump is provided on the first pipeline. One end of the first pipeline is connected to the spinning air conditioning hot water return pipeline, and the outlet pipeline is connected to the spinning air conditioning hot water supply pipeline.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the first pipeline is equipped with an outlet valve and an inlet valve.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the shell and tube heat exchanger is also equipped with a steam trap.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a control valve is provided on the outlet pipeline.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the shell and tube heat exchanger is provided with a compressed air inlet and a compressed air outlet on both sides respectively.

[0010] The beneficial effects of this utility model are as follows: When using this device, first open the inlet valve on the first pipeline, start the water pump, then open the outlet valve of the circulating pump, and then open the control valve on the outlet pipeline of the shell and tube heat exchanger to circulate the hot water. When the air compressor is running, high-temperature compressed air enters from the compressed air inlet of the shell and tube heat exchanger and exchanges heat with the circulating hot water inside the heat exchanger. The cooled compressed air is discharged from the compressed air outlet of the shell and tube heat exchanger, and the heated circulating hot water is used for spinning air conditioning. Since the high-temperature compressed air is cooled by the spinning circulating hot water through the shell and tube heat exchanger, the circulating cooling water valve of the air compressor aftercooler can be appropriately reduced or closed to save circulating cooling water.

However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0013] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0017] See attached diagram. Figure 1 The heat recovery and utilization device for a gas compressor in this embodiment includes a shell-and-tube heat exchanger 1, a hot water return pipeline for spinning air conditioning 2, and a hot water supply pipeline for spinning air conditioning 3. One end of the shell-and-tube heat exchanger 1 is provided with an inlet pipeline 4 and an outlet pipeline 5. One end of the inlet pipeline 4 is provided with a first pipeline 7, and a circulation pump 6 is provided on the first pipeline 7. One end of the first pipeline 7 is connected to the hot water return pipeline for spinning air conditioning 2, and the outlet pipeline 5 is connected to the hot water supply pipeline for spinning air conditioning 3.

[0018] Furthermore, the first pipeline 7 is equipped with an outlet valve 61 and an inlet valve 60.

[0019] The first pipeline 7 is equipped with a circulation pump 6, which, together with the outlet valve 60 and the inlet valve 61, can precisely control the working status of the heat recovery system and ensure the effective transfer of heat energy.

[0020] Furthermore, the shell-and-tube heat exchanger 1 is also equipped with a steam trap 10. The steam trap 10 on the shell-and-tube heat exchanger 1 can promptly drain the condensate in the heat exchanger, prevent scale accumulation, and maintain the efficient operation of the heat exchanger.

[0021] Furthermore, a control valve 50 is installed on the outlet pipe 5.

[0022] Furthermore, the tubular heat exchanger 1 is provided with a compressed air inlet 11 and a compressed air outlet 12 on both sides respectively.

[0023] Working principle: When in use, first open the inlet valve 60 on the first pipeline 7 to start the water pump, then open the outlet valve 61 of the circulating pump 6, and then open the outlet control valve 50 on the outlet pipeline 5 of the shell and tube heat exchanger 1 to circulate the hot water. When the air compressor is running, the high-temperature compressed air enters from the compressed air inlet 11 of the shell and tube heat exchanger 1 and exchanges heat with the circulating hot water inside the shell and tube heat exchanger 1. The cooled compressed air is discharged from the compressed air outlet 12 of the shell and tube heat exchanger 1, and the heated circulating hot water is used for the spinning air conditioning. Since the high-temperature compressed air is cooled by the spinning circulating hot water through the shell and tube heat exchanger 1, the circulating cooling water valve of the air compressor aftercooler can be appropriately reduced or closed to save circulating cooling water.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
