Description

Technical Field

[0001] This utility model belongs to the field of quench tower technology and relates to a novel quench tower. Background Technology

[0002] In industries such as chemical engineering, petroleum refining, and metallurgy, handling high-temperature gases or steam is an unavoidable part of the production process. These high-temperature gases not only carry a large amount of heat energy but may also contain pollutants harmful to the environment. Traditional cooling methods are often inefficient and cannot meet the requirements of modern industry for high efficiency and environmental protection. Therefore, a technology that can quickly and effectively reduce gas temperature is particularly important.

[0003] Quenching towers have emerged as a key piece of equipment for solving this problem. They are specifically designed to rapidly cool high-temperature gases by exchanging heat through direct contact between the cooling medium and the high-temperature gas, thus achieving the purpose of cooling. This cooling method not only effectively prevents the decomposition of heat-sensitive substances but also significantly reduces the emission of pollutants in exhaust gases, contributing to environmental protection.

[0004] Traditionally, quench towers typically use a spray system to spray a cooling medium (usually water) onto the material to be cooled for rapid cooling. This system uses a high-pressure pump to atomize the cooling water into fine droplets, increasing the contact area between the cooling medium and the high-temperature gas, thereby improving heat exchange efficiency. However, despite its excellent cooling effect, this method also has a significant drawback—it consumes a large amount of water. Utility Model Content

[0005] The purpose of this invention is to provide a new type of quench tower that does not require water resources during quenching and can quickly cool high-temperature gases or steam by directly using air cooling.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel quench tower, including a tower body, a quench filling section in the middle of the tower body, an inlet chamber above the quench filling section, a heat pipe connected to the upper end of the tower body communicating with the inlet chamber, an outlet chamber below the quench filling section, a cold pipe connected to the upper part of the outlet chamber at the lower end of the tower body, and a drain pipe connected to the bottom of the outlet chamber at the lower end of the tower body. Valves are provided on the cold pipe and the drain pipe.

[0007] Several quenching channels are provided extending downward through the quenching filling section. Each quenching channel is equipped with a heat exchange tube. The inner diameter of each heat exchange tube is smaller than that of the quenching channel. Heat-conducting fins are provided between the outer wall of each heat exchange tube and the inner wall of the quenching channel. The lower end of each heat exchange tube extends downward through the discharge chamber and out of the tower body to communicate with the outside. A fan channel is provided in the upper part of the tower body. A cooling fan is installed in the fan channel. The upper end of each heat exchange tube extends upward through the inlet chamber and communicates with the fan channel.

[0008] By adopting the above technical solution, during rapid cooling, hot water or hot air enters the room through heat pipes. The hot water and hot air gradually flow downwards through the rapid cooling channel. The cooling fan in the fan channel works to generate a rapid airflow in the heat exchange tubes. After contacting the hot water and hot air in the rapid cooling channel, the airflow carries away the temperature of the hot water or hot air, causing it to cool down rapidly. If only gas is discharged from the room after cooling, the valve on the drain pipe is closed, allowing the cold air to be discharged through the cold pipe. If liquid is discharged from the room after cooling, the valve on the cold pipe is closed, allowing the liquid to be discharged through the drain pipe.

[0009] The present invention is further configured such that the heat pipe is connected downward to multiple nozzles in the indoor entrance.

[0010] The present invention is further configured such that a uniformly distributed layer is provided below the nozzle and above the heat exchange tube in the indoor space, and a plurality of leakage holes are provided through the uniformly distributed layer.

[0011] The present invention is further configured such that one fan channel is provided on each of the opposite sides of the upper end of the tower body, and each heat exchange tube is U-shaped with an opening to one side. The upper end of the heat exchange tube inside the tower body is symmetrically connected to the corresponding fan channel, and the lower end of the heat exchange tube inside the tower body is symmetrically connected to the outside.

[0012] The present invention is further configured such that the heat-conducting fins are multiple strip-shaped fins distributed on the outer periphery of the corresponding heat exchange tube and arranged along its height direction.

[0013] The present invention is further configured such that the heat-conducting fins are spiral fins wound in a spiral shape around the outer periphery of the corresponding heat exchange tube.

[0014] Compared with existing technologies, this utility model adopts a new air-cooling method instead of traditional water spraying for rapid cooling, which does not consume water resources. Furthermore, the multi-channel rapid cooling structure design can effectively improve the cooling speed. At the same time, since no large amount of water vapor is generated during the rapid cooling process, there is no need for additional treatment of the generated water vapor.

[0021] The present invention provides a novel quench tower in further detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar parts.

[0022] Example 1, refer to Figure 1-4 A novel quenching tower includes a tower body 1, a quenching filling section 2 located in the middle of the tower body 1, an inlet chamber 3 located above the quenching filling section 2 within the tower body 1, a heat pipe 4 connected to the inlet chamber 3 at the upper end of the tower body 1, an outlet chamber 5 located below the quenching filling section 2 within the tower body 1, a cold pipe 6 connected to the outlet chamber 5 at the lower end of the tower body 1, and a drain pipe 7 connected to the bottom of the outlet chamber 5 at the lower end of the tower body 1. A valve 8 is installed on both the cold pipe 6 and the drain pipe 7. During quenching, liquid generated in the outlet chamber 5 is discharged through the drain pipe 7.

[0023] Several quenching channels 9 are provided through the downward-penetrating quenching filling section 2. Each quenching channel 9 contains a heat exchange tube 10. The inner diameter of each heat exchange tube 10 is smaller than that of the corresponding quenching channel 9. The gap between the quenching channel 9 and the heat exchange tube 10 facilitates the passage of hot water or hot air. Heat-conducting fins are provided between the outer wall of each heat exchange tube 10 and the inner wall of the corresponding quenching channel 9. The heat-conducting fins are four strip-shaped fins 11 distributed around the outer periphery of the corresponding heat exchange tube 10 and arranged along its height direction. A fan channel 12 is provided on both the left and right sides of the upper part of the tower body 1. Four cooling fans 13 are installed in each fan channel 12. Each heat exchange tube 10 is U-shaped and opens to one side. The upper end of the heat exchange tube 10 in the tower body 1 is symmetrically connected to the corresponding fan channel 12, and the lower end of the heat exchange tube 10 in the tower body 1 is symmetrically connected to the outside. The heat pipe 4 is connected downward to three nozzles 14 inside the inlet chamber 3. A uniform layer 15 is provided below the nozzles 14 and above the heat exchange pipe 10 inside the inlet chamber 3. Several holes 16 are opened through the uniform layer 15 so that hot water or hot air can fall evenly into each quenching channel 9 after contacting the uniform layer 15.

[0024] Example 2, refer to Figure 5 The technical features of Embodiment 2 are the same as those of Embodiment 1 and will not be repeated. The difference lies in the fact that the heat-conducting fins are spiral fins 17 that are spirally wound around the outer periphery of the corresponding heat exchange tube 10, which increases the passage time of hot water or hot air and makes the cooling more complete.

[0025] Working principle: During rapid cooling, hot water or hot air enters the inlet chamber 3 through heat pipe 4. The hot water and hot air gradually flow downward through the rapid cooling channel 9. The cooling fan in the fan channel 12 operates, causing a rapid airflow to be generated in the heat exchange tube 10. After contacting the hot water and hot air in the rapid cooling channel 9, the airflow carries away the temperature of the hot water or hot air, causing it to cool down rapidly. If only gas is present in the outlet chamber 5 after cooling, the valve 8 on the drain pipe 7 is closed, allowing the cold air to be discharged through the cold pipe 6. If liquid is present in the outlet chamber 5 after cooling, the valve 8 on the cold pipe 6 is closed, allowing the liquid to be discharged through the drain pipe 7.

[0026] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0027] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
