Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, specifically a gas pretreatment cooling device. Background Technology

[0002] Chemical plants generate a large amount of wastewater and gas during production and operation. These wastewater and gas need to be analyzed. However, high temperature and high humidity samples can cause inaccurate testing of precision instruments, and in severe cases, damage to the instruments, which can seriously endanger safe production. Therefore, when testing samples, it is necessary to cool and dehydrate the samples. Existing chemical plant exhaust gas pretreatment cooling devices have low cooling efficiency and high cost, failing to meet production needs. Under some harsh working conditions, commercially available cooling equipment is prone to damage and cannot meet the requirements for continuous high-efficiency operation.

[0003] In summary, to improve the stability and economy of chemical plant waste gas pretreatment systems, it is necessary to address the problems of low efficiency, high cost, and susceptibility to damage under harsh operating conditions of existing cooling devices, enabling them to operate continuously and efficiently and meet the stringent requirements of modern chemical production.

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] Refer to the instruction manual appendix Figures 1 to 5 A gas pretreatment cooling device includes a cooling shell 1, a top cover 2 on the top of the cooling shell 1, a sealing component on the top cover 2, an air inlet pipe 4 arranged in a double helix pattern inside the cooling shell 1, a locking mechanism for fixing the cooling shell 1 and the top cover 2, a partition component for positioning the air inlet pipe 4 inside the cooling shell 1, water inlet and outlet components on the bottom of the cooling shell 1 and the top cover 2, and a connecting component for fixing the cooling shell 1 and the top cover 2 to an external support.

[0018] It should be noted that by utilizing the double-helix arrangement of the air intake pipe 4, the airflow impact speed is reduced, significantly extending the gas flow path and time. Combined with the circulating water in the internal cavity space of the cooling shell 1, efficient heat exchange is carried out to achieve rapid cooling. The entire heat exchange process operates automatically based on the principle of thermal circulation, without the need for additional power supply or manual intervention.

[0019] Refer to the instruction manual appendix Figure 1 The sealing assembly includes two fixing rings 31 fixed on the top cover 2 and a sealing sleeve 32 fixed on the fixing rings 31. Both ends of the air intake pipe 4 pass through the corresponding sealing sleeve 32 and are sealed to the sealing sleeve 32.

[0020] It should be noted that the sealing sleeve 32 can ensure that the air intake pipe 4 maintains a tight seal when passing through the top cover 2, prevent the leakage of cooling medium and ensure the airtightness of the internal heat exchange process.

[0021] Refer to the instruction manual appendix Figures 1 to 4 The locking mechanism includes a docking assembly disposed on the outside of the cooling shell 1 and a fixing assembly disposed on the top cover 2. The fixing assembly is used to fix the docking assembly and the top cover 2.

[0022] It should be noted that the locking mechanism provides a reliable connection and quick disassembly capability between the top cover 2 and the cooling shell 1, ensuring the stability of the overall structure of the device.

[0023] Refer to the instruction manual appendix Figures 1 to 4 The docking assembly includes a fixing frame 51 fixed to the outside of the cooling shell 1 and positioning holes 52 opened at the top corners of the top cover 2 and the fixing frame 51, with the corresponding positioning holes 52 axially aligned.

[0024] It should be noted that the docking component enables precise alignment between the top cover 2 and the cooling shell 1, providing a basis for the fixing operation of the locking mechanism.

[0025] Refer to the instruction manual appendix Figures 1 to 4The fixing components include fixing bolts 53 connected to the top cover 2 and fixing nuts 54 connected to the fixing bolts 53. The top cover 2 and the fixing frame 51 are connected by fixing bolts 53.

[0026] It should be noted that the fixing components are connected by simple fixing bolts 53 to firmly lock the aligned docking components, thus completing the final fixing of the top cover 2 and the cooling shell 1.

[0027] Refer to the instruction manual appendix Figure 5 The partition assembly includes a first positioning shell 61 fixed to the bottom of the top cover 2 and a second positioning shell 62 fixed inside the cooling shell 1, with the air intake pipe 4 wrapped around the outside of the first positioning shell 61 and the second positioning shell 62.

[0028] It should be noted that the first positioning shell 61 and the second positioning shell 62 provide stable support and precise positioning for the arrangement of the double helix intake pipe 4, ensuring that it effectively extends the gas flow and is stably surrounded by the cooling medium, thereby optimizing the heat exchange effect.

[0029] Refer to the instruction manual appendix Figure 5 The water inlet and outlet assembly includes water inlet and outlet ports 71 opened on the bottom of the cooling shell 1 and the top cover 2, and internal threads 72 provided inside the water inlet and outlet ports 71. The water inlet and outlet ports 71 are fixedly connected to the external circulating water pipe through the internal threads 72.

[0030] It should be noted that the inlet and outlet 71 serve as the interface channel for the circulation of cooling medium, enabling the cooling water to flow from top to bottom. The natural temperature difference formed by the thermal circulation drives the cooling water to circulate and continuously remove heat.

[0031] Refer to the instruction manual appendix Figure 4 and Figure 5 The connecting assembly includes a fixing plate 81 disposed on the side of the cooling shell 1 and the top cover 2 and a fixing hole 82 opened on the fixing plate 81. The fixing plate 81 is fixed to the external bracket by screws.

[0032] It should be noted that the fixing plate 81 provides an installation interface between the device and the external support structure, ensuring the stable placement of the entire cooling device during operation.

[0033] Working principle: High-temperature exhaust gas first enters the intake pipe 4, which is wrapped in a double spiral shape around the outside of the first positioning shell 61 and the second positioning shell 62 inside the cooling shell 1. This unique arrangement significantly prolongs the flow path and residence time of the exhaust gas in the device, effectively reducing the impact of airflow. At the same time, cooling water is injected through the inlet and outlet 71 of the top cover 2 and flows through the cavity space inside the cooling shell 1 surrounding the intake pipe 4. The heat carried by the exhaust gas is efficiently transferred to the flowing cooling water through the wall of the intake pipe 4. The heated cooling water completes the heat circulation through the temperature difference and finally flows out from the inlet and outlet 71 at the bottom of the cooling shell 1, completing a self-circulating cooling process without external power. The sealing sleeve 32 tightly wraps the two ends of the intake pipe 4 that passes through the top cover 2 to ensure the airtightness of the entire heat exchange cavity. The entire device is firmly installed on the external bracket by the side fixing plate 81 and screws for stable operation.
