Description

Technical Field

[0001] This utility model relates to the field of coolers, and in particular to a cooler structure for cooling gas. Background Technology

[0002] Acetylene is an important organic chemical raw material. Under normal temperature and pressure, acetylene is a colorless and odorless gas. However, in industrial applications, it usually has a distinctive pungent odor due to the presence of small amounts of impurities such as phosphine and hydrogen sulfide. An acetylene generator is a device used to produce acetylene gas and is widely used in industrial and laboratory fields.

[0003] Because acetylene gas contains carbide slag powder and a large amount of saturated water vapor during production, cooling and purification are necessary to ensure its purity and safety. A common method for cooling acetylene gas is through cooling towers. Existing common cooling towers have a multi-layer tray structure, where acetylene gas comes into contact with water flowing from bottom to top on the trays to achieve cooling and dust removal. However, the large number of trays and complex gas flow structure result in significant gas flow resistance, which in turn affects the pressure of the gas generator. Furthermore, because acetylene gas contains impurities, insufficient water quality can lead to tray blockage, requiring frequent equipment maintenance. Utility Model Content

[0004] This invention provides a cooler structure for gas cooling, which can solve the problem of high gas flow resistance in existing coolers.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cooler structure for cooling gas includes:

[0007] The housing has a cooling chamber inside, an air inlet at the bottom, and an air outlet at the top.

[0008] A water inlet pipe is used to connect to a water supply system, and the outlet of the water inlet pipe is located at the middle of the top of the cooling chamber.

[0009] The water distribution cap is located below the outlet of the water inlet pipe, and its top is a conical structure.

[0010] A flow guide plate is fixedly installed on the inner wall of the housing, and the height of the end of the flow guide plate away from the housing is lower than the height of the end connected to the housing.

[0011] A water outlet pipe is located at the bottom end of the housing and communicates with the cooling chamber.

[0012] In one embodiment of this utility model: a water collector is provided below the outlet of the water inlet pipe, and the outlet of the water collector faces the water distribution cap.

[0013] In one embodiment of this utility model, the cooling chamber has a cylindrical structure.

[0014] In one embodiment of this utility model, the diameter of the water inlet pipe is 80mm.

[0015] In one embodiment of this utility model: the water flow velocity at the outlet of the water inlet pipe is 0.5 to 1.2 m / s, and the spray water pressure is 0.1 to 0.3 MPa.

[0016] In one embodiment of this utility model: the number of water-dividing caps is multiple, and a guide plate is correspondingly provided below each water-dividing cap.

[0017] In one embodiment of this utility model, the distance between the uppermost water-dividing cap and the water inlet outlet is 100-150mm.

[0020] In one embodiment of this utility model: an inspection port is provided on the bottom side of the housing.

[0021] According to the cooler structure for gas cooling of this utility model, at least one of the following technical effects is achieved:

[0022] This application features a simple structure and low maintenance costs. It incorporates a water-distributing cap and guide plates to form a continuous and uniform dynamic water curtain, which then constitutes a vertical spray system. The counter-current gas-liquid contact achieves cooling and purification of the gas. The dynamic water curtain provides high coverage and sufficient gas-liquid contact, ensuring the outlet gas temperature remains within a safe range. Furthermore, while maintaining effective gas cooling, the removal of all tray layers eliminates the stepped resistance to gas flow, reducing the pressure within the cooling tower from 6 kPa to below 1 kPa, thereby further lowering the overall pressure of the acetylene generator.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] One common structure of existing acetylene coolers is a multi-layer tray structure, where acetylene gas comes into contact with water flowing from bottom to top on the trays to achieve cooling and dust removal. However, due to the large number of tray layers and the complex gas flow channel structure, the gas flow resistance is relatively high, which in turn affects the pressure of the gas generator. Furthermore, since acetylene gas contains certain impurities, it is prone to tray blockage. If the water quality is insufficient, the blockage rate will be further accelerated. Once the trays are blocked, the gas-liquid contact efficiency will decrease, thus affecting the cooling effect. Therefore, frequent equipment maintenance is required. To solve the above problems, this application provides a cooler structure for gas cooling.

[0030] like Figs. 1-2As shown, this utility model provides a cooler structure for gas cooling, including a shell 1, a water inlet pipe 4, a water distribution cap 5, a guide plate 7, and a water outlet pipe 8. The shell 1 has a cooling chamber inside, which can be a cylindrical structure, or more specifically, a circular structure. The shell 1 has an air inlet 2 at its bottom and an air outlet 3 at its top for air intake and exhaust; the air inlet 2 can be an air inlet pipe located near the bottom side. The air outlet 3 can be an air outlet pipe located in the middle of the top. The bottom side of the shell 1 can have an inspection port 9, which is fitted with a closed door, to allow for maintenance of the internal structure of the shell 1 when needed. Specifically, as an example, the diameter of the shell 1 can be 1.4m and the height can be 4.9m.

[0031] Please see Figs. 1-2 In one embodiment of this utility model, the water inlet pipe 4 is used to connect to the water supply system to supply water to the cooling chamber, and the outlet of the water inlet pipe 4 is located at the middle of the top of the cooling chamber; specifically, the diameter of the water inlet pipe 4 can be 80mm. The water flow velocity at the outlet of the water inlet pipe 4 can be 0.5 to 1.2m / s, and the spray water pressure can be 0.1 to 0.3MPa.

[0032] Please see Figs. 1-2 In one embodiment of this utility model, the water-dividing cap 5 is located below the outlet of the water inlet pipe 4, and its top end is conical. Specifically, the top end of the water-dividing cap 5 can be set as a conical structure to disperse the water flow transported by the water inlet pipe 4 into a water curtain. The water-dividing cap 5 can be made of corrosion-resistant material (such as 316L stainless steel or Hastelloy) to adapt to high-impurity water environments. The water-dividing cap 5 can be connected to the inner wall of the housing 1 through a rod-like structure. That is, the two ends of the connecting rod are respectively connected to the inner wall of the housing 1 and the water-dividing cap 5.

[0033] Please see Figs. 1-2 In one embodiment of this utility model, the guide plate 7 is fixedly disposed on the inner wall of the housing 1, and the height of the end of the guide plate away from the housing 1 is lower than the height of the end connected to the housing 1, that is, the guide plate 7 can be inclined, and its inclination angle can be 45°; the guide plate 7 can be an annular structure, specifically, the guide plate 7 can be a trumpet-shaped structure. The guide plate 7 is used to collect the water flow on the inner wall and guide it to the water distribution cap 5 of the next layer, while forming a water curtain and ensuring uniform water flow distribution, avoiding local resistance concentration.

[0034] Please see Figs. 1-2In one embodiment of this utility model, the water outlet pipe 8 is disposed at the bottom end of the housing 1 and communicates with the cooling chamber for water discharge. The water outlet pipe 8 can be connected to a water supply system for water recycling. The height of the water outlet pipe 8 can be lower than the height of the air inlet 2 to ensure low air intake resistance. Alternatively, the height of the water outlet pipe 8 can be higher than the height of the air inlet 2, so that the acetylene air inlet 2 is below the liquid surface and can fully contact the water, achieving cooling and purification effects.

[0035] Please see Figs. 1-2 In one embodiment of this utility model, a water collector 6 can be provided below the outlet of the water inlet pipe 4, and the outlet of the water collector 6 faces the water distribution cap 5. The water collector 6 can be a box structure with an opening at the top and an outlet at the bottom for water discharge. The water collector 6 is provided for water flow transition to ensure water flow stability.

[0036] Please see Figs. 1-2 In one embodiment of this utility model, there are multiple water-dividing caps 5, and a guide plate 7 is correspondingly arranged below each water-dividing cap 5. As an example, there can be two water-dividing caps 5, with the distance between the uppermost water-dividing cap 5 and the outlet of the inlet pipe 4 being 100-150mm. Similarly, the longitudinal distance between the lower water-dividing cap 5 and the guide plate 7 above it is 100-150mm. This ensures that a water curtain can be sufficiently formed. The lower water-dividing cap 5 can be larger than the upper water-dividing cap 5, or all water-dividing caps 5 can be set to the same size; there is no limitation here.

[0037] The working principle of this utility model:

[0038] Water flows into the cooling chamber through inlet pipe 4. For example, the spray water volume can be 20.0 m³ / h. 3 The water pressure can be 0.2 MPa. After being guided and diverted by the water distribution cap 5, a continuous and uniform dynamic water curtain with a thickness of 5-8 mm is formed. One end of the first water curtain is located at the water distribution cap 5, and the other end is located on the inner wall of the shell 1. Then, the water flows through the inner wall of the shell 1 and is guided by the guide plate 7 to the water distribution cap 5 located at the second layer, forming the second water curtain. Then, under the guidance of the second water distribution cap 5, a third water curtain is formed. After flowing through the inner wall of the shell 1 and the second guide plate 7, a fourth water curtain is formed, thus constituting a vertical spray system. Acetylene gas enters through the air inlet 2 located at the bottom of the shell 1, and the acetylene gas flow rate can be 1000-1600 m³ / h. 3 / h, the inlet temperature is 80±5℃, and then the gas flows upward in the cooling chamber. The airflow and water flow flow in opposite directions and come into contact. The airflow passes through the water curtain, thereby completing the cooling, slag removal and foam removal of the gas. The acetylene after cooling and purification is discharged through the gas outlet 3 at the top of the shell 1. The temperature of the gas outlet 3 is 60±5℃.

[0039] This application features a simple structure and low maintenance costs. It incorporates a water-distributing cap 5 and guide plates 7 to form a continuous and uniform dynamic water curtain, which then constitutes a vertical spray system. The counter-current gas-liquid contact completes the cooling and purification of the gas. The dynamic water curtain has high coverage, ensuring sufficient gas-liquid contact, and the outlet gas temperature can be controlled within a safe range. Furthermore, while ensuring effective gas cooling, the removal of all tray layers eliminates the stepped resistance to gas flow, reducing the pressure inside the cooling tower from 6 kPa to below 1 kPa, thereby further reducing the overall pressure of the acetylene generator. Simultaneously, the removal of the tray layer structure eliminates the problem of mud accumulation and tray blockage, allowing the device to adapt to high-turbidity water environments, reducing the need for frequent maintenance, and significantly improving production efficiency and safety.
