DETAILED DESCRIPTION
[0016] The utility model provides the following description of reference drawing to help comprehensively understand various embodiments of the utility model as defined by the claim and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.
[0017] In the description of the utility model, the orientation description, such as the orientation or positional relation of up, down, front, back, left, right and the like indication based on the orientation or positional relation shown in the drawing, is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.
[0018] It should be understood that when an element (e.g., a first element) is "connected" with another element (e.g., a second element), the element can be directly connected with the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.
[0019] The embodiment of the utility model provides a kind of styrene buried tank cooling system, as shown in Figure 1 The buried tank 100 is buried in the ground, and a deep pit can be dug on the ground in advance, and the buried tank 100 is buried in the deep pit. The buried tank 100 is used for storing styrene, and the buried tank 100 has a discharge port and a return port. The discharge port is used for styrene to flow out of the buried tank 100, and the return port is used for styrene to flow back to the buried tank 100.
[0020] The discharge port, the first circulating pump 300, the heat exchange cooling system 200 and the return port are sequentially connected. The first circulating pump 300 is used to circulate and pump the styrene stored in the buried tank 100, and deliver the styrene to the heat exchange cooling system 200. The heat exchange cooling system 200 is used to cool the styrene pumped out by the first circulating pump 300. The cooled styrene flows back to the buried tank 100 through the return port. The temperature sensor 400 is arranged at the top of the buried tank 100 and inserted into the buried tank 100. The temperature sensor 400 is used to detect the temperature of the styrene stored in the buried tank 100. The heat exchange cooling system 200, the first circulating pump 300 and the temperature sensor 400 are electrically connected with the control module 500.
[0021] The temperature sensor 400 can send the detected temperature data to the control module 500, and the control module 500 can send corresponding control instructions to the heat exchange cooling system 200 and the first circulating pump 300 according to the set program, so that the heat exchange cooling system 200 and the first circulating pump 300 start working or stop working. When the temperature detected by the temperature sensor 400 is greater than the set temperature, the styrene stored in the buried tank 100 needs to be cooled, and the control module 500 can control the heat exchange cooling system 200 and the first circulating pump 300 to start working. The first circulating pump 300 circulates and pumps the styrene stored in the buried tank 100, and the heat exchange cooling system 200 cools the styrene pumped out by the first circulating pump 300, so as to gradually cool the styrene stored in the buried tank 100. This way does not need to lift the buried tank 100 and weld it for modification, greatly reduces the cost, has very low safety risk, and has both economy and safety. At the same time, the whole system can work automatically, the temperature control is accurate, the styrene stored in the buried tank 100 can be cooled in time, and it is more intelligent. The whole scheme can adopt a fully enclosed pipeline, greatly reducing the risk of leakage and organic matter volatilization.
[0022] When the temperature detected by the temperature sensor 400 is less than the preset temperature, the styrene stored in the buried tank 100 does not need to be cooled, and the control module 500 can control the heat exchange cooling system 200 and the first circulating pump 300 to stop working, so as to avoid waste of electric energy.
[0023] It should be noted that the control module 500 of the embodiment can be a PLC, the input / output interface of which is connected with the heat exchange cooling system 200, the first circulating pump 300 and the temperature sensor 400, and through the built-in control program, the control process described above can be automatically implemented, which is a common technical means in the industry, and the specific structure will not be described again. The heat exchange cooling system 200 can be a system capable of refrigeration and heat exchange.
[0024] In some embodiments, the heat exchange cooling system 200 can include a cooling water tank and a refrigeration device, the cooling water tank is loaded with cooling water, and the refrigeration device is used for refrigerating the cooling water. The pipeline connected with the first circulating pump 300 and the material return port can pass through the cooling water tank, and the styrene in the pipeline is cooled by the cooling water.
[0025] In some embodiments, the heat exchange cooling system 200 comprises a heat exchanger 210, a cooling water unit 220 and a second circulating pump 230, the heat exchanger 210 has a first heat exchange channel and a second heat exchange channel which can exchange heat with each other, one end of the first heat exchange channel, the cooling water unit 220, the second circulating pump 230 and the other end of the first heat exchange channel are connected in sequence, two ends of the second heat exchange channel are connected with the first circulating pump 300 and the return port respectively, and the cooling water unit 220 and the second circulating pump 230 are electrically connected with the control module 500. The second circulating pump 230 is used for circulating and conveying the cooling water in the first heat exchange channel, and the cooling water unit 220 is used for refrigerating the cooling water.
[0026] When the temperature detected by the temperature sensor 400 is greater than the set temperature, the control module 500 can control the first circulating pump 300, the cooling water unit 220 and the second circulating pump 230 to start working, the cooling water is continuously conveyed to the first heat exchange channel, the styrene stored in the buried tank 100 is continuously conveyed to the second heat exchange channel, the cooling water in the second heat exchange channel exchanges heat with the styrene in the second heat exchange channel, so as to reduce the temperature of the styrene.
[0027] In some embodiments, the styrene buried tank cooling system further comprises a buried pool 600, the buried pool 600 is arranged underground, the buried tank 100 is placed in the buried pool 600, and the buried pool 600 is further filled with a buried material 610. The buried pool 600 is used to isolate the soil and underground water, so as to avoid eroding the buried tank 100, ensure the safety of the buried tank 100 and prolong the service life thereof. The buried pool 600 can be piled up by concrete. The buried material 610 also plays a certain protective role for the buried tank 100, and helps to limit the movement of the buried tank 100, so that the buried tank 100 can be kept in a relatively fixed position. In addition, the buried material 610 also has a certain heat preservation effect.
[0028] In some embodiments, the buried material 610 is sand and gravel, which is easy to obtain, has a certain strength, can be used for a long time, and has a lower cost.
[0029] In some embodiments, a sunshade cover (not shown in the figure) is further fixed above the buried pool 600, the sunshade cover can be in a flat plate shape or an umbrella shape, a support can be fixed on the top surface of the side wall of the buried pool 600 or the ground, and the sunshade cover is fixed on the top of the support to shield the buried pool 600, so as to play a role of shading and rainproof for the buried tank 100.
[0030] In some embodiments, the top of the buried tank 100 is also connected with a feed pipe 110 and a discharge pipe, both of which extend laterally above the buried pool 600 to the outside of the buried pool 600. Since the size of the entire buried tank 100 is large, if the feed pipe 110 and the discharge pipe are directly arranged on the top of the buried tank 100 without extending outward, it is inconvenient to receive and feed materials. Both the feed pipe 110 and the discharge pipe extend to the outside of the buried pool 600, so there is more space for receiving and feeding materials.
[0031] In some embodiments, the discharge port and the return port are arranged on the top of the buried tank 100, which can avoid the discharge port and the return port being squeezed by the buried material. Two connecting pipes are arranged in the buried tank 100, the upper ends of the two connecting pipes are connected with the discharge port and the return port respectively, and the lower ends of the two connecting pipes extend to the position of the bottom of the buried tank 100, so that the transportation of styrene can be carried out when the buried tank 100 is not filled with styrene.
[0032] The terms and words used in the above description and claims are not limited by the literal meaning, but are used by the applicant only to enable a clear and consistent understanding of the present application. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present application is provided only for illustration, not for limitation of the present application as defined by the appended claims and their equivalents.
