Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a multi-cycle cooling device for chemical production. Background Technology

[0002] Cooling devices are a common type of process equipment in the chemical industry, used to effectively reduce the heat generated during processes.

[0003] In chemical production, it is necessary to cool the heat sources generated during production; otherwise, sudden temperature changes can damage equipment, and thermal stress may lead to equipment fatigue and cracking, affecting the service life of the equipment. Therefore, we propose a multi-circulation cooling device for chemical production to solve the aforementioned technical problems. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the needle and its main purpose is to provide a multi-cycle cooling device for chemical production, which aims to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a primary cooling container, a secondary cooling container, a tertiary cooling container, and a quaternary cooling container, which are sequentially connected end-to-end, and each connection point has a partition fixedly installed on its inner side. The partition is provided with a flow guiding mechanism. Heat exchange tubes are fixedly installed inside each of the primary, secondary, tertiary, and quaternary cooling containers and above the partitions. The primary cooling container is connected to the secondary cooling container, the secondary cooling container is connected to the tertiary cooling container, and the tertiary cooling container is connected to the quaternary cooling container through a return flow mechanism provided on its outer side.

[0006] As a preferred embodiment, the flow guiding mechanism includes a flow guiding groove opened at the top of the partition, and a flow guiding pipe fixedly installed at the bottom of the partition, the flow guiding pipe being connected to the flow guiding groove.

[0007] As a preferred embodiment, thermometers are installed on the outer sides of the primary, secondary, tertiary, and quaternary cooling containers.

[0008] As a preferred embodiment, the primary cooling container, the secondary cooling container, the tertiary cooling container, and the quaternary cooling container are sequentially equipped with liquid inlets and liquid outlets. The liquid inlets are connected to the input end of the heat exchange tubes, and the liquid outlets are connected to the output end of the heat exchange tubes.

[0009] As a preferred embodiment, a cover is fixedly installed on the top of the primary cooling container, and a feed inlet is fixedly installed on the top of the cover.

[0010] As a preferred embodiment, the reflux mechanism includes a first circulation pipe installed on the primary and secondary cooling containers, a second circulation pipe installed on the secondary and tertiary cooling containers, and a third circulation pipe installed on the tertiary and quaternary cooling containers. A first solenoid valve is fixedly installed on each of the first, second, and third circulation pipes.

[0011] As a preferred embodiment, a support leg is fixedly installed at the bottom of the four-stage cooling container, and a discharge pipe is fixedly installed at the bottom of the four-stage cooling container and inside the support leg. A second solenoid valve is fixedly installed on the discharge pipe, and the discharge pipe is connected to the top of the cover.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0013] In this device, the heat source undergoes initial cooling in a primary cooling container, followed by secondary cooling in a secondary cooling container, tertiary cooling in a tertiary cooling container, and quaternary cooling in a quaternary cooling container. During the cooling process, the device controls whether to circulate the heat source to the next stage through a reflux mechanism based on the cooled temperature. When the temperature of the heat source inside the quaternary cooling container does not reach the set cooling temperature, the heat source in the quaternary cooling container is guided to the tertiary cooling container through the reflux mechanism to achieve circulatory cooling. This process continues, with the heat source inside the secondary and tertiary cooling containers of the previous stage circulating back to the previous stage when the temperature does not reach the set cooling temperature. By using primary, secondary, tertiary, and quaternary cooling containers for progressive cooling, the impact of rapid temperature changes on the equipment can be reduced, the risk of wear and corrosion can be lowered, and the equipment lifespan can be extended.

[0014] In addition, the temperature is gradually reduced through a series of cooling systems—primary, secondary, tertiary, and quaternary—maximizing the recovery and utilization of waste heat. This helps improve overall energy efficiency and reduce energy waste.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Please see Figures 1 to 5 This utility model provides a multi-stage circulating cooling device for chemical production, including a primary cooling container 1, a secondary cooling container 2, a tertiary cooling container 3, and a quaternary cooling container 4. The primary cooling container 1, the secondary cooling container 2, the tertiary cooling container 3, and the quaternary cooling container 4 are connected sequentially, and a partition 18 is fixedly installed on the inner side of each connection. A flow guiding mechanism is provided on the partition 18. Heat exchange tubes 17 are fixedly installed inside the primary cooling container 1, the secondary cooling container 2, the tertiary cooling container 3, and the quaternary cooling container 4 and above the partition 18. The primary cooling container 1 is connected to the secondary cooling container 2, the secondary cooling container 2 is connected to the tertiary cooling container 3, and the tertiary cooling container 3 is connected to the quaternary cooling container 4 through a return flow mechanism provided on its outer side.

[0025] In this embodiment, it is mainly used to cool the heat source generated in chemical production. The heat source is mainly high-temperature gas, high-temperature liquid, and heat generated by chemical reactions, reactors, or other production processes. The heat source is cooled for the first time through the first-stage cooling container 1, the second-stage cooling container 2, the third-stage cooling container 3, and the fourth-stage cooling container 4. During the cooling process, the reflux mechanism is used to control whether to circulate the heat source to the next stage for cooling based on the cooled temperature. When the temperature of the heat source inside the fourth-stage cooling container 4 does not reach the set cooling temperature, the heat source in the fourth-stage cooling container 4 is guided to the third-stage cooling container 3 through the reflux mechanism to achieve circulatory cooling. Similarly, when the temperature of the heat source inside the second-stage cooling container 2 and the third-stage cooling container 3 does not reach the set cooling temperature, it is refluxed to the previous stage for circulatory cooling. By cooling in stages through the first-stage cooling container 1, the second-stage cooling container 2, the third-stage cooling container 3, and the fourth-stage cooling container 4, the impact of rapid temperature changes on the equipment can be reduced, the risk of wear and corrosion can be reduced, and the equipment life can be extended.

[0026] In addition, the temperature is gradually reduced through a cycle of primary cooling container 1, secondary cooling container 2, tertiary cooling container 3, and quaternary cooling container 4, maximizing the recovery and utilization of waste heat. This helps improve overall energy efficiency and reduce energy waste.

[0027] Please see Figures 1 to 5 The flow guiding mechanism includes a flow guiding groove 19 opened at the top of the partition 18, and a flow guiding pipe 20 fixedly installed at the bottom of the partition 18, which is connected to the flow guiding groove 19. The return flow mechanism includes a first circulation pipe 8 installed on the primary cooling container 1 and the secondary cooling container 2, a second circulation pipe 9 installed on the secondary cooling container 2 and the tertiary cooling container 3, and a third circulation pipe 10 installed on the tertiary cooling container 3 and the quaternary cooling container 4. A first solenoid valve 11 is fixedly installed on the first circulation pipe 8, the second circulation pipe 9, and the third circulation pipe 10. The first solenoid valve 11 receives the temperature signal from the thermometer 14 and controls the heat flow by opening and closing the first solenoid valve 11. Whether the heat source is circulated depends on the flow guiding mechanism, which guides the heat source in the primary cooling container 1, secondary cooling container 2, tertiary cooling container 3, and quaternary cooling container 4. The heat flow rate output speed of the guide pipe 20 is less than the circulation speed of the heat source by the first circulation pipe 8, second circulation pipe 9, and third circulation pipe 10. The heat source in the quaternary cooling container 4 can be circulated to the tertiary cooling container 3 through the third circulation pipe 10, the heat source in the tertiary cooling container 3 can be circulated to the secondary cooling container 2 through the second circulation pipe 9, and the heat source in the secondary cooling container 2 can be circulated to the primary cooling container 1 through the first circulation pipe 8 for re-cooling.

[0028] Please see Figures 1 to 5Thermometers 14 are installed on the outside of the primary cooling container 1, the secondary cooling container 2, the tertiary cooling container 3 and the quaternary cooling container 4 respectively. Thermometers 14 are used to monitor the internal temperature of the heat source thermometer in the primary cooling container 1, the secondary cooling container 2, the tertiary cooling container 3 and the quaternary cooling container 4 in real time. When the temperature of the primary cooling container reaches the set value, the heat source is circulated to the next stage through the reflux mechanism.

[0029] Please see Figures 1 to 5 The primary cooling container 1, the secondary cooling container 2, the tertiary cooling container 3, and the quaternary cooling container 4 are sequentially equipped with liquid inlets 12 and liquid outlets 13. The liquid inlet 12 is connected to the input end of the heat exchange tube 17, and the liquid outlet 13 is connected to the output end of the heat exchange tube 17. The heat source is cooled by the heat exchange tube 17 and the coolant inside it. The coolant is an existing mechanism, which will not be described in detail in this article.

[0030] Please see Figures 1 to 5 A cover 6 is fixedly installed on the top of the primary cooling container 1, and a feed inlet 7 is fixedly installed on the top of the cover 6. A support leg 5 is fixedly installed on the bottom of the fourth-stage cooling container 4. A discharge pipe 15 is fixedly installed on the bottom of the fourth-stage cooling container 4 and inside the support leg 5. A second solenoid valve 16 is fixedly installed on the discharge pipe 15. The discharge pipe 15 is connected to the cover 6. The heat source enters through the feed inlet 7. After being cooled step by step by the primary cooling container 1, the secondary cooling container 2, the tertiary cooling container 3 and the fourth-stage cooling container 4, the second solenoid valve 16 is opened and the heat source is discharged through the discharge pipe 15.
