Description

Technical Field

[0001] This application relates to the field of flue gas cooling technology, and more particularly to a cooling system. Background Technology

[0002] In industrial production, high-temperature flue gas is often generated. High-temperature flue gas needs to be cooled. On the one hand, this can reduce the risk of secondary pollution caused by high-temperature flue gas. On the other hand, by reducing the flue gas temperature, the risk of high-temperature damage to flue gas treatment equipment can be reduced.

[0003] A common drawback of flue gas cooling systems is their limited range of adjustment for cooling effectiveness. For example, a high-efficiency flue gas cooler (CN110282859A) disclosed in the prior art suffers from the disadvantage of inconvenient adjustment of its cooling effect. These drawbacks of flue gas cooling systems reduce their adaptability and flexibility. Utility Model Content

[0004] One of the technical problems this application aims to solve is: how to facilitate the adjustment of the cooling effect of the cooling system on the flue gas.

[0005] To address the aforementioned technical problems, this application provides a cooling system including a conveying channel and a cooling assembly. The cooling assembly includes a first cooling channel, a second cooling channel, and a transition channel. The first cooling channel, the transition channel, and the second cooling channel are sequentially connected. The inlet of the first cooling channel and the outlet of the second cooling channel are respectively connected to the conveying channel. The conveying channel is equipped with a switching component. Along the conveying direction of the conveying channel, the inlet of the first cooling channel and the outlet of the second cooling channel are located on opposite sides of the switching component. The transition channel is located at the bottom of the first and second cooling channels and includes a first discharge channel.

[0006] In some embodiments, the connection between the first discharge channel and the transition channel is provided corresponding to the first cooling channel and the second cooling channel.

[0007] In some embodiments, the first discharge channel is provided with a valve and a discharger. The valve is used to open and close the first discharge channel. The discharger is located in the first discharge channel along the conveying direction of the first discharge channel, and the valve is located behind the discharger.

[0008] In some embodiments, the transition channel and the conveying channel are disposed opposite to each other along a first direction, and the first cooling channel and the second cooling channel are disposed between the transition channel and the conveying channel.

[0009] In some embodiments, the conveying channel includes a first segment and a second segment connected together, a first cooling channel and a second cooling channel respectively connected to the first segment, a transition channel and the first segment being disposed opposite to each other along a first direction, and the second segment extending along the first direction.

[0010] In some embodiments, the conveying channel is provided with a flue gas treatment component, which includes a denitrification catalyst.

[0011] In some embodiments, the conveying channel includes a first segment and a second segment connected together, the first cooling channel and the second cooling channel are respectively connected to the first segment, and the denitrification catalyst is disposed in the second segment.

[0012] In some embodiments, the cooling assembly further includes a cooling component for cooling the first cooling channel and / or the second cooling channel.

[0013] In some embodiments, the cooling component includes a blower section.

[0014] In some embodiments, the conveying channel is provided with a second discharge channel.

[0015] Through the above technical solution:

[0016] 1. By setting up a first cooling channel and a second cooling channel, the cooling effect of the flue gas can be adjusted. Taking the first and second cooling channels as air-cooled as an example, air can be blown into the first and second cooling channels to cool them, thereby cooling the flue gas. At this time, air can be blown into the first cooling channel only, or into the second cooling channel only, or into both cooling channels simultaneously, as needed. This allows the cooling effect of the cooling system on the flue gas to be adjusted within a wide range, increasing the adaptability and flexibility of the cooling system.

[0017] 2. The transition channel is located at the bottom of the first cooling channel and the second cooling channel, so that solids in the flue gas can fall from the first cooling channel and the second cooling channel into the transition channel, and then be discharged through the first discharge channel located in the transition channel. On the one hand, the transition channel facilitates the collection of solids. On the other hand, when the flue gas enters the transition channel from the first cooling channel and then enters the second cooling channel from the transition channel, some solids cannot follow the flue gas into the second cooling channel under the action of gravity, so that the transition channel can filter the flue gas.

[0030] See Figure 1 and Figure 2 This application provides a cooling system including a conveying channel 3 and a cooling assembly. The cooling assembly includes a first cooling channel 4, a second cooling channel 5, and a transition channel 6. The first cooling channel 4, the transition channel 6, and the second cooling channel 5 are connected in sequence. The inlet of the first cooling channel 4 and the outlet of the second cooling channel 5 are respectively connected to the conveying channel 3. The conveying channel 3 is provided with a switching component 13. Along the conveying direction of the conveying channel 3, the inlet of the first cooling channel 4 and the outlet of the second cooling channel 5 are respectively located on both sides of the switching component 13. The transition channel 6 is located at the bottom of the first cooling channel 4 and the second cooling channel 5, and the transition channel 6 is provided with a first discharge channel 7.

[0031] Conveying channel 3 is used to convey flue gas.

[0032] The cooling assembly is used to cool the flue gas. That is, when the flue gas is in the first cooling channel 4 and the second cooling channel 5, it can be cooled so that the temperature of the flue gas meets the requirements.

[0033] The connection point between the first cooling channel 4 and the conveying channel 3 can be close to the entrance of the conveying channel 3, while the connection point between the second cooling channel 5 and the conveying channel 3 can be far away from the entrance of the conveying channel 3.

[0034] The first cooling channel 4, the second cooling channel 5, and the transition channel 6 can form a flue gas cooling circuit, so that after the flue gas enters the first cooling channel 4, it can return to the conveying channel 3 from the second cooling channel 5.

[0035] The first cooling channel 4 and the second cooling channel 5 are connected by a transition channel 6, which makes it easier to adjust the distance between the first cooling channel 4 and the second cooling channel 5 compared to directly connecting the first cooling channel 4 and the second cooling channel 5.

[0036] The switch component 13 controls the opening and closing of the conveying channel 3. The inlet of the first cooling channel 4 and the outlet of the second cooling channel 5 are located on both sides of the switch component 13, allowing the conveying channel 3 to have two states. One state is when the switch component 13 closes the conveying channel 3, indicating that the flue gas needs cooling. In this state, the flue gas cannot directly move to the outlet of the conveying channel 3; instead, it enters the flue gas cooling circuit from the first cooling channel 4, is cooled by the first cooling channel 4 and the second cooling channel 5, and then returns to the conveying channel 3. The other state is when the switch component 13 opens, allowing the flue gas to move directly to the outlet of the conveying channel 3, indicating that the flue gas does not need cooling. In this state, the flue gas does not need to enter the flue gas cooling circuit, reducing the path length of the flue gas movement and allowing it to be discharged more quickly, thus increasing the efficiency of flue gas treatment.

[0037] It should be noted that when the switch component 13 is opened, only a very small portion of the flue gas may enter the flue gas cooling circuit. This is because the equipment connected to the outlet end of the conveying channel 3 has an attractive effect on the flue gas. At the same time, when the flue gas enters the conveying channel 3 from the inlet end, the flue gas has kinetic energy to move towards the outlet end of the conveying channel 3. Therefore, only a very small portion of the flue gas may enter the flue gas cooling circuit, and this very small portion of flue gas loss can be ignored.

[0038] The first cooling channel 4 and the second cooling channel 5 can be cooled by air cooling, liquid cooling, or other heat exchange equipment, so that the medium in the first cooling channel 4 and the second cooling channel 5 can also be cooled.

[0039] By setting up a first cooling channel 4 and a second cooling channel 5, the cooling effect of the flue gas can be adjusted. Taking the use of air cooling for the first cooling channel 4 and the second cooling channel 5 as an example, air can be blown into the first cooling channel 4 and the second cooling channel 5 to cool them, thereby cooling the flue gas. At this time, air can be blown into the first cooling channel 4 only, or into the second cooling channel 5 only, or into both cooling channels 4 and 5 simultaneously, so that the cooling effect of the cooling system on the flue gas can be adjusted within a large range, increasing the adaptability and flexibility of the cooling system.

[0040] The first discharge channel 7 is used to discharge solids from the transition channel 6.

[0041] In this embodiment, the connection points between the first cooling channel 4 and the second cooling channel 5 and the conveying channel 3 can be located at the top of the first cooling channel 4 and the second cooling channel 5, respectively.

[0042] The transition channel 6 is located at the bottom of the first cooling channel 4 and the second cooling channel 5, allowing solids in the flue gas to fall from the first cooling channel 4 and the second cooling channel 5 into the transition channel 6, and then be discharged through the first discharge channel 7 located in the transition channel 6. On the one hand, the transition channel 6 facilitates the collection of solids; on the other hand, when the flue gas enters the transition channel 6 from the first cooling channel 4 and then enters the second cooling channel 5 from the transition channel 6, some solids cannot follow the flue gas into the second cooling channel 5 under the action of gravity, so that the transition channel 6 can filter the flue gas.

[0043] See Figure 1 and Figure 2 In some embodiments, the connection between the first discharge channel 7 and the transition channel 6 is provided corresponding to the first cooling channel 4 and the second cooling channel 5.

[0044] That is, the connection between the first cooling channel 4 and the transition channel 6, and the connection between the second cooling channel 5 and the transition channel 6 are respectively set opposite to the connection between the first discharge channel 7 and the transition channel 6.

[0045] The advantages of this design are twofold. First, the inlet of the discharge channel can be made as large as possible, allowing the first discharge channel 7 to correspond to the first cooling channel 4 and the second cooling channel 5. This makes it easier for solid materials to enter the first discharge channel 7, increasing the efficiency of solid material discharge. Second, the first cooling channel 4 and the second cooling channel 5 can share a single first discharge channel 7, reducing costs.

[0046] See Figure 1 and Figure 2In some embodiments, the first discharge channel 7 is provided with a valve 11 and a discharger 12. The valve 11 is used to open and close the first discharge channel 7. The discharger 12 is provided in the first discharge channel 7, and the valve 11 is located behind the discharger 12 along the conveying direction of the first discharge channel 7.

[0047] Valve 11 can be selected from existing products of a suitable type, the structure and working principle of which are well known to those skilled in the art and will not be described in detail here.

[0048] The valve 11 can control the opening and closing of the first discharge channel 7, thereby controlling the discharge of material from the first discharge channel 7.

[0049] The unloader 12 facilitates the quantitative discharge of materials through the first discharge channel 7. The structure and working principle of the unloader 12 are well known to those skilled in the art and will not be described in detail here.

[0050] Valve 11 is located behind unloader 12, that is, above unloader 12, so that when valve 11 is closed, solid material cannot enter unloader 12.

[0051] See Figure 1 and Figure 2 In some embodiments, the transition channel 6 and the conveying channel 3 are arranged opposite to each other along a first direction, and the first cooling channel 4 and the second cooling channel 5 are arranged between the transition channel 6 and the conveying channel 3.

[0052] The first direction can be the direction shown by the Z-axis in the figure, or it can be the vertical direction.

[0053] The first cooling channel 4 and the second cooling channel 5 are positioned between the transition channel 6. This arrangement allows the first and second cooling channels 4 and 5 to be arranged side-by-side. When the temperature of the first and second cooling channels 4 and 5 is reduced by air cooling, the direction of airflow can be adjusted to control the cooling effect, making it easier to adjust the cooling efficiency. Furthermore, adjusting the length of the transition channel 6 allows for adjustment of the distance between the first and second cooling channels 4 and 5, reducing the risk of interference between them.

[0054] See Figure 1 and Figure 2 In some embodiments, the conveying channel 3 includes a first segment 1 and a second segment 2 connected together, a first cooling channel 4 and a second cooling channel 5 respectively connected to the first segment 1, a transition channel 6 and the first segment 1 are arranged opposite to each other along a first direction, and the second segment 2 extends along the first direction.

[0055] The switch component 13 can also be located in the first segment 1.

[0056] The first segment 1 can be located at the top of the first cooling channel 4 and the second cooling channel 5.

[0057] The extension direction of the first segment 1 can be perpendicular to the first direction.

[0058] The second segment 2 extends along the first direction, allowing the first segment 1 and the second segment 2 to form a bent structure, reducing the space occupied by the conveying channel 3 and making the cooling system structure more compact.

[0059] In the embodiment where the first direction is vertical, the second segment 2 can extend downwards vertically. When flue gas enters the second segment 2, solids in the flue gas can move towards the bottom of the second segment 2, facilitating collection and aggregation of solids. Furthermore, a second discharge channel 10 can be provided at the bottom end of the second segment 2 to facilitate the discharge of solids. The flue gas outlet of the second segment 2 can be located on the side wall of the second segment 2.

[0060] See Figure 1 and Figure 2 In some embodiments, the conveying channel 3 is provided with a flue gas treatment component, which includes a denitrification catalyst 8.

[0061] The denitrification catalyst 8 can be used to remove nitrogen oxides from flue gas. The specific chemical principle by which the denitrification catalyst 8 treats flue gas is well known to those skilled in the art and will not be elaborated here.

[0062] The flue gas treatment component may also include a support 9, which is disposed in the conveying channel 3 and is used to support the denitrification catalyst 8.

[0063] See Figure 1 and Figure 2 In some embodiments, the conveying channel 3 includes a first segment 1 and a second segment 2 connected together, a first cooling channel 4 and a second cooling channel 5 respectively connected to the first segment 1, and a denitrification catalyst 8 disposed in the second segment 2.

[0064] By placing the denitrification catalyst 8 in the second section 2, the denitrification catalyst 8 comes into contact with the cooled flue gas, which can reduce the risk of deactivation of the denitrification catalyst 8 under high temperature conditions.

[0065] See Figure 1 and Figure 2 In some embodiments, the cooling assembly further includes a cooling component 16 for cooling the first cooling channel 4 and / or the second cooling channel 5.

[0066] The cooling component 16 cools the first cooling channel 4 and the second cooling channel 5, thereby allowing the flue gas to be cooled through the first cooling channel 4 and the second cooling channel 5.

[0067] The cooling component 16 can adjust its cooling channels. For example, the cooling component 16 can cool only the first cooling channel 4, or only the second cooling channel 5, or simultaneously cool the first cooling channel 4 and the second cooling channel 5, so that the cooling effect of the cooling component on the flue gas can be adjusted.

[0068] See Figure 1 and Figure 2 In some embodiments, the cooling component 16 includes a blower section.

[0069] The blower section can be equipped with a second fan, and the speed of the second fan can be adjusted to regulate the cooling effect of the blower section.

[0070] Airflow is blown from the blower into the first cooling channel 4 and the second cooling channel 5, so that the first cooling channel 4 and the second cooling channel 5 can be cooled by air.

[0071] Multiple blower sections can be set.

[0072] See Figure 1 and Figure 2 In some embodiments, the conveying channel 3 is provided with a second discharge channel 10.

[0073] In this embodiment, the second discharge channel 10 may also be equipped with a valve 11 and a discharger 12.

[0074] See Figure 1 and Figure 2 In some embodiments, a first detection component 14 and a second detection component 15 may be respectively provided on both sides of the switch component 13 for detecting the temperature of the flue gas.

[0075] The first detection component 14 can be used to detect the temperature of the flue gas before it enters the first cooling channel 4.

[0076] The second detection component 15 can be used to detect the temperature of the cooled flue gas to determine whether the cooled flue gas temperature meets the requirements, and thus control the cooling effect.

[0077] The first detection component 14 and the second detection component 15 can be selected from existing products. For example, the first detection component 14 and the second detection component 15 can each include a sensor and a processor. The sensor is electrically connected to the processor. The sensor is used to measure the flue gas temperature. The specific principles of the sensor measuring temperature and the specific principles of the processor controlling the sensor are well known to those skilled in the art and will not be described here.

[0078] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described.
