Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and more specifically, to a quench cooler. Background Technology

[0002] In existing technologies, indirect quench coolers are generally used to enable the reuse of heat exchange medium and heat recovery in quench coolers. High-temperature raw materials flow through the heat exchange zone via internal pipes, while low-temperature heat exchange medium flows outside the heat exchange zone. The high-temperature raw materials exchange heat with the low-temperature medium through the pipe walls. However, the presence of pipes leads to slow heat transfer between the two, and the direct flow of the low-temperature cooling medium through the outer wall of the pipe results in a short heat exchange time between the low-temperature medium and the high-temperature raw materials. Consequently, the utilization rate of the low-temperature medium is low, and the heat exchange efficiency is also low. Therefore, a technical solution is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a quencher that can slow down the flow of low-temperature media.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a quencher, including a heat exchange section, a feeding section, and a discharging section. The heat exchange section includes a shell and a heat exchange tube assembly. The heat exchange tube assembly includes multiple pipes, multiple first baffles, and multiple second baffles. The two ends of the pipes are respectively connected to the feeding section and the discharging section. The pipes are used for high-temperature raw materials, and the space between the pipes and the shell is used for low-temperature media. The first baffles and the second baffles are arranged along the length of the pipes, with a second baffle spaced apart between two first baffles. Both the first baffles and the second baffles have notches, and the notches of the first baffles and the second baffles are staggered.

[0006] Furthermore, the cryogenic medium flowing through the first baffle plate flows to the second baffle plate through the gap in the first baffle plate, and the cryogenic medium flowing through the second baffle plate flows to the next first baffle plate through the gap in the second baffle plate.

[0007] Furthermore, the outer casing includes a first water inlet and a first water outlet, which are located on the side wall of the outer casing. The first water inlet is close to the feeding part, and the first water outlet is close to the discharging part. A baffle is provided on the inner wall of the outer casing, and the baffle is located between the first water inlet and the pipe.

[0008] Furthermore, the baffle plate is fixedly connected to the inner wall of the outer casing, and the end of the baffle plate connected to the outer casing is away from the feed section.

[0009] Furthermore, the distance between adjacent first and second baffles is L, and the length of L gradually increases from the feed section to the discharge section.

[0010] Furthermore, it includes a guide pipe located at the center of the outer shell, the guide pipe covering a portion of the pipe located at the center of the outer shell, and a second water outlet provided at one end of the guide pipe near the discharge section, the second water outlet extending out of the side wall of the outer shell, and the second water outlet being connected to an external water pump.

[0011] Furthermore, the guide pipe is provided with multiple second water inlets, which are arranged in a ring around the upper sidewall of the guide pipe.

[0012] Furthermore, the feeding section includes a feeding port and a feeding chamber, the feeding port being connected to the feeding chamber, and a plurality of pipes being connected to the feeding chamber. The discharging section includes a discharging port and a discharging chamber, the plurality of pipes being connected to the discharging chamber, the discharging port being connected to the discharging chamber, and the portion of the discharging chamber connected to the discharging port being a cone with a gradually decreasing diameter.

[0013] The beneficial effects of this utility model are:

[0014] 1. The heat exchange section of this utility model is internally equipped with interlaced first and second baffles, which slows down the flow velocity of the low-temperature medium flowing between the shell and the pipe, thereby increasing the contact time between the low-temperature medium and the pipe and improving the utilization rate of the low-temperature medium.

[0015] 2. In this embodiment, the guide pipe installed in the heat exchange tube group can allow a portion of the low-temperature medium that has just entered the outer shell to enter the guide pipe through the second water inlet, thereby reducing the temperature of the low-temperature medium flowing in the guide pipe, improving the heat exchange efficiency of the middle part of the heat exchange tube group, and thus improving the cooling effect of the entire heat exchange tube group.

[0021] The technical solutions in this embodiment 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.

[0022] like Figures 1-4 As shown, this embodiment discloses a quencher, including a heat exchange section 1, a feeding section 2, and a discharging section 3. The heat exchange section 1 includes a shell 11 and a heat exchange tube assembly 12. The heat exchange tube assembly 12 includes multiple pipes 121, multiple first baffles 124, and multiple second baffles 125. The feeding section 2 and the discharging section 3 are located at opposite ends of the heat exchange section 1. The two ends of the pipes 121 are connected to the feeding section 2 and the discharging section 3, respectively. The pipes 121 extend along the length of the shell 11. The multiple pipes 121 are arranged in a ring array from the inside to the outside. The end of the pipe 121 near the feeding chamber 22 is connected and fixed by a fixing plate 122, so that the pipe 1... The feeding end structure of 21 is more stable. The feeding part 2 includes a feeding port 21 and a feeding chamber 22. The feeding port 21 is connected to the feeding chamber 22. Multiple pipes 121 are connected to the feeding chamber 22. The feeding chamber 22 can pre-store the material and disperse the high-temperature material entering the feeding chamber 22 into multiple pipes 121. The discharging part 3 includes a discharging port 31 and a discharging chamber 32. Multiple pipes 121 are connected to the discharging chamber 32. The discharging port 31 is connected to the discharging chamber 32. The part of the discharging chamber 32 connected to the discharging port 31 is a cone with a gradually decreasing diameter. The cone-shaped discharging chamber 32 can collect the material after heat exchange through the cone-shaped discharging chamber 32 and concentrate it for discharge at the discharging port 31.

[0023] The outer casing 11 includes a first inlet 111 and a first outlet 112, which are located on the side wall of the outer casing 11. The first inlet 111 is close to the feed section 2, and the first outlet 112 is close to the discharge section 3. The low-temperature medium flows from the first inlet 111 to the first outlet 112. A baffle 113 is provided on the inner wall of the outer casing 11, which is located between the first inlet 111 and the pipe 121 to prevent the low-temperature medium from entering the outer casing 11. The direct impact of the warm medium on the pipe 121 can protect the pipe 121. The baffle 113 is fixedly connected to the inner wall of the outer shell 11. The end of the baffle 113 connected to the outer shell 11 is far away from the feed part 2, so that the low temperature medium entering the first inlet 111 will not flow directly to the first outlet 112 along the flow path, but can enter the outer shell 11 to the sides of the baffle 113 and the direction close to the feed part 2, so that the low temperature medium that just enters the outer shell 11 can be fully utilized for heat exchange.

[0024] High-temperature raw materials pass through pipe 121, while low-temperature media pass between pipe 121 and outer shell 11. Heat exchange occurs between the high-temperature raw materials and the low-temperature media through the side wall of pipe 121. Multiple first baffles 124 and multiple second baffles 125 are arranged along the length of pipe 121, with a second baffle 125 spaced between every two first baffles 124. Both first and second baffles 124 and 125 have notches, formed between the first or second baffle and the inner wall of outer shell 11. The notches of the flow plates 125 are staggered. The first baffle 124 and the second baffle 125 are arranged perpendicular to the axial direction of the outer shell 11. The first baffle 124 and the second baffle 125 can partially block the flow of the low-temperature medium. Most of the blocked low-temperature medium needs to pass through the notches to flow downward. The first baffle 124 and the second baffle 125 can slow down the flow rate of the low-temperature medium, increase the contact time between the low-temperature medium and the pipe 121, ensure that the low-temperature medium fully exchanges heat with the high-temperature material in the pipe 121, and improve the heat exchange utilization rate of the low-temperature medium.

[0025] The first baffle 124 and the second baffle 125 are symmetrically arranged on both sides of the length of the heat exchange tube assembly 12. The low-temperature medium flowing through the first baffle 124 flows to the second baffle 125 through the gap in the first baffle 124, and the low-temperature medium flowing through the second baffle 125 flows to the next first baffle 124 through the gap in the second baffle 125. Thus, the flow direction of the low-temperature medium inside the outer shell 11 is generally a maze-shaped tortuous flow direction, which increases the contact time of the low-temperature medium with the pipe 121.

[0026] like Figure 3As shown, the distance between adjacent first baffle 124 and second baffle 125 is L. The length of L gradually increases from the feed section 2 to the discharge section 3. Since the low temperature medium has the lowest temperature when it enters from the first inlet 111, the distance between the first baffle 124 and second baffle 125 near the first inlet 111 is the smallest. That is, the flow rate of the low temperature medium flowing through this part is the slowest, so that the low temperature medium that just entered can be fully utilized. The closer to the discharge section 3, the longer L becomes.

[0027] This embodiment also includes a guide pipe 123, which is located at the center of the outer shell 11. The guide pipe 123 covers a portion of the pipe 121 located at the center of the outer shell 11. Since the low-temperature medium enters the interior from the side wall of the outer shell 11, and since the pipe 121 has a structure that spreads outward from the center, the heat exchange temperature of the pipe 121 located at the center is significantly higher than that of the pipe 121 located on the outer side. This results in a poor heat exchange effect for the pipe 121 located in the middle. The guide pipe 123 is provided with multiple second inlets 1231, which are arranged in a ring on the upper side wall of the guide pipe 123. The positions of the second inlets 1231 are the same as those of the first inlets 1231. Corresponding to 11, a portion of the low-temperature medium that has just entered the outer shell 11 can enter the guide pipe 123 through the second inlet 1231, thereby lowering the temperature of the low-temperature medium flowing in the guide pipe 123 and improving the heat exchange efficiency of the pipe 121 in the middle of the heat exchange tube group 12. The guide pipe 123 is provided with a second outlet 1232 at one end near the discharge section 3. The second outlet 1232 extends out of the side wall of the outer shell 11 and is connected to an external water pump. The water pump connected to the guide pipe 123 can pull the water in the guide pipe 123. The water pump connected to the guide pipe 123 and the water pump connected to the first outlet 112 are connected to the same cold source.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
