Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flue gas cooling, in particular to a cooling device. BACKGROUND

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

[0003] The cooling area is an important factor affecting the cooling effect of the flue gas cooling device, and the size of the cooling area determines the heat exchange area of the flue gas and the cooling medium, so the cooling area directly determines the cooling effect of the flue gas cooling device. The common flue gas cooling device has the disadvantage that the cooling area is fixed and cannot be adjusted. For example, the prior art high-efficiency flue gas cooler (CN110282859A) is such a structure. The above-mentioned shortcomings of the cooling device reduce the cooling flexibility of the flue gas cooling device. CONTENT OF THE UTILITY MODEL

[0004] One of the technical problems to be solved by the present application is how to adjust the cooling area of the cooling device.

[0005] To solve the above technical problems, the present application provides a cooling device, which comprises a conveying channel and a cooling assembly. The inlet end of the conveying channel is provided with a first detection component. The cooling assembly comprises 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 communicated, the inlet of the first cooling channel and the outlet of the second cooling channel are respectively communicated with the conveying channel, the conveying channel is provided 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 respectively located on the two sides of the switching component, and the transition channel is provided with a second detection component.

[0006] In some embodiments, the transition channel and the conveying channel are oppositely arranged along a first direction, and the cooling assembly further comprises a plurality of fans, and the plurality of fans are arranged along the first direction.

[0007] In some embodiments, the transition channel and the conveying channel are oppositely arranged along a first direction, and the first cooling channel and the second cooling channel are arranged between the transition channel and the conveying channel.

[0008] In some embodiments, the conveying channel comprises a first segment and a second segment which are communicated, the first cooling channel and the second cooling channel are respectively communicated with the first segment, the transition channel and the first segment are oppositely arranged along a first direction, and the second segment extends along the first direction.

[0009] In some embodiments, the conveying channel is provided with a discharge channel.

[0010] In some embodiments, the discharge channel is provided in plurality, and the plurality of discharge channels are arranged along the conveying direction of the conveying channel.

[0011] In some embodiments, the cross-sectional area of the inlet end of the discharge channel gradually increases from the side close to the middle of the discharge channel to the side away from the middle of the discharge channel.

[0012] In some embodiments, the switching component comprises a partition plate, and the partition plate is rotationally connected to the conveying channel.

[0013] In some embodiments, the conveying channel is provided with a flue gas treatment component, and the flue gas treatment component comprises a denitration catalyst.

[0014] In some embodiments, the conveying channel comprises a first segment and a second segment in communication, the first cooling channel and the second cooling channel are respectively in communication with the first segment, and the denitration catalyst is arranged in the second segment.

[0015] Through the above technical solutions:

[0016] 1. By arranging the first cooling channel and the second cooling channel, the cooling area of the cooling device can be adjusted. For example, in the case of using air cooling for the first cooling channel and the second cooling channel, only the first cooling channel can be air cooled, only the second cooling channel can be air cooled, or the first cooling channel and the second cooling channel can be cooled at the same time. Thus, the cooling area of the cooling device can be adjusted as needed.

The first detection component is arranged at the inlet end of the conveying channel, and the temperature of the flue gas can be detected by the first detection component to determine whether the flue gas needs to be cooled by the cooling assembly. The cooling effect of the flue gas is controlled by the second detection component. If the temperature of the flue gas reaches the requirement after being cooled by the first cooling channel, the flue gas does not need to be cooled by the second cooling channel. If the temperature of the flue gas still cannot meet the requirement after being cooled by the first cooling channel, the flue gas can be further cooled by the second cooling channel.

[0030] Reference Figure 1 and Figure 2 , the embodiment of the present application provides a cooling device, comprising a conveying channel 3 and a cooling assembly. The inlet end of the conveying channel 3 is provided with a first detection component 7. The cooling assembly comprises a first cooling channel 4, a second cooling channel 6 and a transition channel 5, the first cooling channel 4, the transition channel 5 and the second cooling channel 6 are communicated in sequence, the inlet of the first cooling channel 4 and the outlet of the second cooling channel 6 are communicated with the conveying channel 3 respectively, 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 6 are located on the two sides of the switching component 13 respectively, and the transition channel 5 is provided with a second detection component 8.

[0031] The conveying channel 3 is used for conveying flue gas.

[0032] The cooling assembly is used for cooling treatment of flue gas. That is, when the flue gas is in the first cooling channel 4 and the second cooling channel 6, it can be cooled and treated, so that the temperature of the flue gas can meet the requirements.

[0033] The communication position of the first cooling channel 4 and the conveying channel 3 can be close to the inlet of the conveying channel 3, and the communication position of the second cooling channel 6 and the conveying channel 3 can be away from the inlet of the conveying channel 3.

[0034] The first cooling channel 4, the second cooling channel 6 and the transition channel 5 can form a flue gas cooling loop, 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 6.

[0035] The first cooling channel 4 and the second cooling channel 6 are communicated through the transition channel 5, which facilitates adjustment of the spacing between the first cooling channel 4 and the second cooling channel 6 compared to directly communicating the first cooling channel 4 and the second cooling channel 6.

[0036] The switch component 13 is used to control the opening and closing of the conveying channel 3, and the inlet of the first cooling channel 4 and the outlet of the second cooling channel 6 are respectively located on both sides of the switch component 13, so that the conveying channel 3 can have two states, one is that the switch component 13 closes the conveying channel 3, which is the state that the flue gas needs to be cooled, at this time the flue gas cannot directly move to the outlet end of the conveying channel 3, the flue gas enters the flue gas cooling loop from the first cooling channel 4, and the flue gas is cooled through the first cooling channel 4 and the second cooling channel 6, and then returns to the conveying channel 3. The other is that the switch component 13 is opened, and the flue gas can directly move to the outlet end of the conveying channel 3, which is the state that the flue gas does not need to be cooled, and the flue gas does not need to enter the flue gas cooling loop, reducing the path length of the flue gas movement, so that the flue gas can be discharged faster, increasing the processing efficiency of the flue gas.

[0037] It should be noted that when the switch component 13 is opened, only a very small part of the flue gas may enter the flue gas cooling loop, because the equipment connected to the outlet end of the conveying channel 3 has an attraction to the flue gas, and at the same time when the flue gas enters the conveying channel 3 from the inlet end of the conveying channel 3, the flue gas has kinetic energy to move to the outlet end of the conveying channel 3, so only a very small part of the flue gas may enter the flue gas cooling loop. The loss of this small part of the flue gas can be ignored.

[0038] The first cooling channel 4 and the second cooling channel 6 can use air cooling, or liquid cooling, or other heat exchange equipment to exchange heat with the first cooling channel 4 and the second cooling channel 6 for cooling, and thus the medium in the first cooling channel 4 and the second cooling channel 6 can also be cooled.

[0039] The flow rates of the first cooling channel 4 and the second cooling channel 6 can be the same or different.

[0040] By setting the first cooling channel 4 and the second cooling channel 6, the cooling area of the cooling device can be adjusted. Taking the example of using air cooling for the first cooling channel 4 and the second cooling channel 6, air cooling can be performed only on the first cooling channel 4, or only on the second cooling channel 6, or on both the first cooling channel 4 and the second cooling channel 6, so that the cooling area of the cooling device can be adjusted as needed.

[0041] The first detection component 7 is configured to detect the temperature of the flue gas in the conveying passage 3.

[0042] The second detection component 8 is configured to detect the temperature of the flue gas in the transition passage 5.

[0043] The first detection component 7 and the second detection component 8 can be selected from existing products. For example, the first detection component 7 and the second detection component 8 can each include a sensor and a processor, the sensor is electrically connected to the processor, the sensor is configured to measure the temperature of the flue gas, and the specific principle of the sensor for measuring the temperature and the specific principle of the processor for controlling the sensor are known to those skilled in the art, which will not be described here.

[0044] The first detection component 7 is arranged at the inlet end of the conveying passage 3, and the temperature of the flue gas can be detected by the first detection component 7 to determine whether the flue gas needs to be cooled by the cooling assembly.

[0045] Since the transition passage 5 is arranged between the first cooling passage 4 and the second cooling passage 6, the cooling effect of the flue gas can be controlled by the second detection component 8. That is, if the temperature of the flue gas reaches the requirement after being cooled by the first cooling passage 4, the flue gas does not need to be cooled by the second cooling passage 6. If the temperature of the flue gas still cannot meet the requirement after being cooled by the first cooling passage 4, the flue gas can be further cooled by the second cooling passage 6.

[0046] Referring to Figure 1 and Figure 2 In some embodiments, the transition passage 5 and the conveying passage 3 are arranged opposite to each other along a first direction, and the cooling assembly further includes a plurality of fans, and the plurality of fans are arranged along the first direction.

[0047] The transition passage 5 and the conveying passage 3 are arranged opposite to each other along the first direction, so that the first cooling passage 4 and the second cooling passage 6 are at least partially arranged between the transition passage 5 and the conveying passage 3.

[0048] The first direction can be the direction indicated by the Z axis in the figure, and the first direction can also be a vertical direction.

[0049] The fan can be selected to be of a type with adjustable gears.

[0050] The plurality of fans are arranged along the first direction, which facilitates adjusting the cooling effect of the cooling passage corresponding to the fan. For example, the plurality of fans are used for air-cooled first cooling passage 4, if it is necessary to increase the cooling effect, the number of started fans or the gear of the fan can be increased. Conversely, if it is necessary to reduce the cooling effect, the number of started fans or the gear of the fan can be reduced.

[0051] Similarly, the second cooling channel 6 can also be provided with multiple fans in the first direction to adjust the cooling effect.

[0052] In some embodiments, the transition channel 5 and the conveying channel 3 are arranged opposite to each other in the first direction, and the first cooling channel 4 and the second cooling channel 6 are arranged between the transition channel 5 and the conveying channel 3. Figure 1 Figure 2 The first cooling channel 4 and the second cooling channel 6 are arranged between the transition channel 5, on one hand, so that the first cooling channel 4 and the second cooling channel 6 can be arranged side by side, and on the other hand, by adjusting the length of the transition channel 5, the spacing between the first cooling channel 4 and the second cooling channel 6 can be adjusted, thereby reducing the risk of interference between the first cooling channel 4 and the second cooling channel 6.

[0053] The first cooling channel 4 and the second cooling channel 6 are arranged between the transition channel 5, on one hand, so that the first cooling channel 4 and the second cooling channel 6 can be arranged side by side, and on the other hand, by adjusting the length of the transition channel 5, the spacing between the first cooling channel 4 and the second cooling channel 6 can be adjusted, thereby reducing the risk of interference between the first cooling channel 4 and the second cooling channel 6.

[0054] In some embodiments, the conveying channel 3 includes a first segment 1 and a second segment 2 that are in communication, the first cooling channel 4 and the second cooling channel 6 are respectively in communication with the first segment 1, the transition channel 5 and the first segment 1 are arranged opposite to each other in the first direction, and the second segment 2 extends in the first direction. Figure 1 Figure 2 The extension direction of the first segment 1 can be perpendicular to the first direction.

[0055] The second segment 2 extends in the first direction, so that the first segment 1 and the second segment 2 can form a bent structure, thereby reducing the space occupied by the conveying channel 3 and making the cooling device more compact.

[0056] In addition, in embodiments where the first direction is a vertical direction, the first cooling channel 4, the second cooling channel 6, and the second segment 2 can be arranged above the first segment 1, and the solid matter generated in the first cooling channel 4, the second cooling channel 6, and the second segment 2 can fall into the first segment 1, thereby facilitating collection and cleaning.

[0057] In some embodiments, the conveying channel 3 is provided with a discharge channel 9.

[0058] The discharge channel 9 is used to discharge the solid matter in the conveying channel 3. Figure 1 Figure 2 The discharge channel 9 can be provided with a valve 10 to control the opening and closing of the discharge channel 9.

[0059] The discharge channel 9 is used to discharge the solid matter in the conveying channel 3.

[0060] The discharge channel 9 can be provided with a valve 10 to control the opening and closing of the discharge channel 9.

[0061] ​​​The discharge channel 9 can also be provided with a discharger to control the discharge of the solid objects. The structure and working principle of the discharger are known to those skilled in the art, and will not be described here.

[0062] In some embodiments, the discharge channel 9 is provided in multiple numbers, and the multiple discharge channels 9 are arranged along the conveying direction of the conveying channel 3. Figure 1 Figure 2 The multiple discharge channels 9 increase the discharge effect of the solid objects, and when part of the discharge channels 9 are under maintenance, the other discharge channels 9 can continue to work, so that the equipment does not need to be shut down during the maintenance of the discharge channels 9, and the production efficiency is improved.

[0063] In some embodiments, the discharge channel 9 can be provided in three numbers, and the three discharge channels 9 are respectively arranged at the positions corresponding to the first cooling channel 4, the second cooling channel 6 and the second segment 2.

[0064] In some embodiments, the discharge channel 9 can be provided in three numbers, and the three discharge channels 9 are respectively arranged at the positions corresponding to the first cooling channel 4, the second cooling channel 6 and the second segment 2. Figure 1 Figure 2 The three discharge channels 9 are respectively arranged at the positions corresponding to the first cooling channel 4, the second cooling channel 6 and the second segment 2, which means that the positions where the first cooling channel 4, the second cooling channel 6 and the second segment 2 communicate with the first segment 1 are respectively arranged opposite to the positions where the three discharge channels 9 communicate with the first segment 1. This arrangement has the advantage that the solid objects in the first cooling channel 4, the second cooling channel 6 and the second segment 2 can directly fall into the corresponding discharge channels 9, thereby reducing the risk of accumulation of the solid objects in the conveying channel 3.

[0065] In some embodiments, the discharge channel 9 can be provided in three numbers, and the three discharge channels 9 are respectively arranged at the positions corresponding to the first cooling channel 4, the second cooling channel 6 and the second segment 2.

[0066] In some embodiments, the discharge channel 9 can be provided in three numbers, and the three discharge channels 9 are respectively arranged at the positions corresponding to the first cooling channel 4, the second cooling channel 6 and the second segment 2.

[0067] In some embodiments, the inlet end of the discharge channel 9 gradually increases in cross-sectional area from the side close to the middle of the discharge channel 9 to the side away from the middle of the discharge channel 9. Figure 1 Figure 2 For example, the inlet end of the discharge channel 9 can be frustum-shaped or prism-shaped.

[0068] The inlet end of the discharge channel 9 gradually increases in cross-sectional area from the side close to the middle of the discharge channel 9 to the side away from the middle of the discharge channel 9, so that the diameter of the inlet end of the discharge channel 9 gradually decreases from the edge to the middle of the discharge channel 9. This structure makes it easier for the solid objects to fall into the discharge channel 9, thereby increasing the discharge effect of the solid objects.

[0069] In some embodiments, the inlet end of the discharge channel 9 gradually increases in cross-sectional area from the side close to the middle of the discharge channel 9 to the side away from the middle of the discharge channel 9.

[0070] In some embodiments, the inlet end of the discharge channel 9 gradually increases in cross-sectional area from the side close to the middle of the discharge channel 9 to the side away from the middle of the discharge channel 9. Figure 1 ​​​and Figure 2 In some embodiments, the switching component 13 comprises a partition, which is rotatably connected to the conveying passage 3.

[0071] The driving structure of the partition can be selected from existing structures, which will not be described here.

[0072] When the partition rotates, the conveying passage 3 can be blocked by the partition, or the conveying passage 3 can be opened by the partition.

[0073] Referring to Figure 1 and Figure 2 In some embodiments, the conveying passage 3 is provided with a flue gas treatment component, which comprises a denitration catalyst 11.

[0074] The denitration catalyst 11 can be used to remove nitrogen oxides in flue gas. The specific chemical principle of the denitration catalyst 11 for treating flue gas is known to those skilled in the art, which will not be described here.

[0075] The flue gas treatment component can further comprise a support portion 12, which is arranged in the conveying passage 3 and used to support the denitration catalyst 11.

[0076] Referring to Figure 1 and Figure 2 In some embodiments, the conveying passage 3 comprises a first segment 1 and a second segment 2 which are in communication, the first cooling passage 4 and the second cooling passage 6 are respectively in communication with the first segment 1, and the denitration catalyst 11 is arranged in the second segment 2.

[0077] By arranging the denitration catalyst 11 in the second segment 2, the reaction can be completed in an environment with a higher temperature, so that the reaction speed is faster, and the processing efficiency is improved.
