Description

Technical Field

[0001] This utility model belongs to the field of petrochemical technology, and in particular relates to a petrochemical oil and natural gas storage device. Background Technology

[0002] Petrochemicals is an industrial sector that uses petroleum and natural gas as raw materials to produce fuels, chemical raw materials and products through processes such as cracking, reforming and separation. Its core lies in converting hydrocarbon compounds into high-value-added products. Storage equipment is required in the storage of petroleum and natural gas to ensure their safe storage.

[0003] Traditional oil and gas storage equipment typically uses metal tanks with sealed structures. The tank surface usually has only a simple insulation layer or relies on natural convection for heat dissipation. In sustained high-temperature environments or during long-term storage, heat generated inside the equipment due to chemical reactions of the medium, external temperature conduction, and pressure changes is difficult to dissipate effectively, causing the tank temperature to rise continuously. When the temperature is too high, the light components in the stored medium evaporate rapidly, and the heavy components are prone to polymerization reactions, altering the physicochemical properties of the medium. Simultaneously, high temperatures significantly reduce the creep resistance of the tank material, posing safety hazards such as tank deformation and weld cracking. While existing equipment uses heat sinks or injects cooling water into the outer jacket of the tank for cooling, the heat sinks have limited heat transfer efficiency due to low contact with the tank surface and insufficient distribution density. The cooling water jacket relies on an external circulation pump to maintain water flow, resulting in high energy consumption and potential pipe blockage due to water impurities. Under extreme conditions, thermal stress may cause the tank to peel off from the jacket structure, further exacerbating localized heat accumulation and hindering its use.

[0004] To address these issues, we provide a petrochemical oil and gas storage device. Utility Model Content

[0005] The purpose of this utility model is to provide a petrochemical oil and gas storage device. By combining heat dissipation components and cooling components, it solves the problem that existing petrochemical oil and gas storage devices lack rapid heat dissipation and cooling functions, which can easily lead to a reduction in the safety performance of the storage device in high-temperature environments.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a petrochemical oil and natural gas storage device, comprising a shell, a heat dissipation assembly, and a cooling assembly. The shell has an inner cavity containing a tank, the surface of which is fixedly connected to the inner wall of the shell. The heat dissipation assembly includes a control box, the front of which is fixedly connected to the shell. An adjustment mechanism is located within the control box, and a nozzle is fixedly connected to the rear of the adjustment mechanism, penetrating the control box. An exhaust mechanism is connected to the bottom of the shell. The cooling assembly includes a cooling chamber, the left side of which is connected to the shell via a conduit. A cooler is located at the front of the cooling chamber, and the cold end of the cooler extends into the inner cavity of the cooling chamber. A pump is fixedly connected to the top of the cooling chamber, and the water inlet at the bottom of the pump extends into the inner cavity of the cooling chamber. A flexible hose is connected to the top of the pump, with the end of the hose furthest from the pump connected to the nozzle.

[0008] The present invention is further configured such that the adjusting mechanism includes a first motor, the bottom of the first motor is fixedly connected to the inner wall of the control box, and screws are fixedly connected to both sides of the output end of the first motor. A threaded sleeve is threadedly connected to the surface of the screw, and the rear side of the threaded sleeve passes through the control box and is fixedly connected to the nozzle. The first motor can cooperate with the screw to control the movement of the threaded sleeve. The movement of the threaded sleeve can adjust the position of the nozzle so that it can evenly spray cooling water onto the surface of the tank.

[0009] The present invention is further configured such that the exhaust mechanism includes an exhaust pipe, the top of which extends through the inner cavity of the housing, and the end of the exhaust pipe away from the housing is connected to a suction shell. A blower is fixedly connected between the two sides of the inner cavity of the suction shell, and a filter screen is fixedly connected to the top of the suction shell. The exhaust pipe can inject air into the housing, and the blower can cooperate with the suction shell to deliver external air into the exhaust pipe, so that the air on the surface of the tank flows rapidly, accelerating its evaporation rate, and allowing the cooling water to carry away the heat from the surface of the tank during evaporation.

[0010] The present invention is further configured such that a second motor is fixedly connected to the top of the cooling box, the bottom of the second motor is fixedly connected to the cooling box, and a stirring rod is fixedly connected to the bottom of the output end of the second motor through the cooling box. The second motor can control the stirring rod to rotate, and the stirring rod can stir the water inside the cooling box so that it can fully contact the cold end of the refrigerator and accelerate the cooling speed.

[0011] The present invention is further provided that a support frame is fixedly connected to both sides of the bottom of the shell, and a mounting hole is provided on both sides of the support frame. The support frame can stably support the shell, and the mounting hole can install and fix the support frame to prevent the shell from shifting.

[0012] The present invention is further configured such that a sliding rod is fixedly connected to the front side of the housing, and sliding sleeves are slidably connected to both sides of the surface of the sliding rod. The top of the sliding sleeves is fixedly connected to the nozzle. The sliding rod and sliding sleeves can limit the nozzle, so that it can move smoothly left and right and prevent it from shaking during the movement.

[0013] The present invention is further configured such that an injection pipe is connected to the top of the tank, and a heat sink is fixedly connected to the hot end of the front side of the cooler. The injection pipe facilitates the injection of oil and natural gas into the tank for storage, and the heat sink increases the heat dissipation effect of the hot end of the cooler.

[0014] The present invention is further configured such that the surface of the tank body is fixedly connected to the inner wall of the shell by a partition, and a drain opening is provided at the bottom of the left side of the partition. The partition can separate the shell and the tank body, increase the cooling effect on the tank body, and the drain opening can facilitate the delivery of cooling water.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model utilizes a heat dissipation component and an adjustment mechanism within the control box to drive the nozzle to move laterally and reciprocally, ensuring that cooling water evenly covers the surface of the tank. Combined with an exhaust mechanism, this continuously delivers airflow into the inner cavity of the shell, accelerating water film evaporation and carrying away heat. This solves the problem of insufficient heat transfer efficiency caused by the low fit of traditional heat sinks. The adjustment mechanism achieves precise nozzle displacement control through the threaded engagement of a screw and a threaded sleeve, avoiding localized heat dissipation blind spots. Simultaneously, the exhaust mechanism's fan and filter work together to filter impurities when introducing external air, preventing particulate matter from adhering to the tank surface and affecting heat dissipation. By combining spraying with forced convection, the surface temperature of the tank is effectively reduced, preventing material degradation and medium evaporation caused by high temperatures.

[0017] 2. This utility model utilizes a cooling component and an independent circulating cooling water system. The chiller continuously cools the water in the cooling tank, and the pump and hoses deliver the low-temperature water to the nozzles. This replaces the traditional jacketed cooling method that relies on an external water source, reducing energy consumption and avoiding the risk of pipe blockage. The second motor drives the stirring rod to rotate, ensuring a uniform water temperature distribution in the cooling tank and guaranteeing full contact between the cold end of the chiller and the water, thus improving cooling efficiency. At the same time, the design of the baffles and drainage openings allows for the orderly discharge of condensate from the shell, reducing the risk of structural delamination caused by temperature difference stress. While maintaining the low temperature of the tank, this significantly improves the operational stability of the equipment under extreme conditions. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a petrochemical oil and natural gas storage device, including a shell 1, a heat dissipation component 3, and a cooling component 4. The inner cavity of the shell 1 is provided with a tank 2, and the surface of the tank 2 is fixedly connected to the inner wall of the shell 1. The heat dissipation component 3 includes a control box 31, the front side of which is fixedly connected to the shell 1. The inner cavity of the control box 31 is provided with an adjustment mechanism 32, and the rear side of the adjustment mechanism 32 passes through the control box 31 and is fixedly connected with a nozzle 33. The bottom of the shell 1 is connected to an exhaust mechanism 34. The cooling component 4 includes a cooling box 41, the left side of which is connected to the shell 1 through a conduit. The front side of the cooling box 41 is provided with a cooler 42, and the rear cold end of the cooler 42 passes through the inner cavity of the cooling box 41. The top of the cooling box 41 is fixedly connected with a pump body 43, and the water inlet at the bottom of the pump body 43 passes through the inner cavity of the cooling box 41. The top of the pump body 43 is connected with a hose 44, and the end of the hose 44 away from the pump body 43 is connected to the nozzle 33.

[0028] Specifically: the shell 1 can temporarily store the water for cooling; the adjustment mechanism 32 can adjust the position of the nozzle 33 so that it can evenly spray cooling water onto the surface of the tank 2; the exhaust mechanism 34 can inject air into the shell 1 so that the air on the surface of the tank 2 flows rapidly, and the flowing air accelerates the evaporation rate of the water, so that the water evaporates and carries away the heat on the surface of the tank 2, preventing heat accumulation; the cooler 42 can lower the temperature of the cooling water inside the cooling box 41 so that it is in a low temperature state; and the pump body 43 and the hose 44 are used to transport the cooling water to the nozzle 33 and spray it onto the surface of the tank 2 to improve the cooling effect on the tank 2.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the adjustment mechanism 32 includes a first motor 321. The bottom of the first motor 321 is fixedly connected to the inner wall of the control box 31. Screws 322 are fixedly connected to both sides of the output end of the first motor 321. Threaded sleeves 323 are threadedly connected to the surface of the screws 322. The rear side of the threaded sleeves 323 penetrates the control box 31 and is fixedly connected to the nozzle 33. The exhaust mechanism 34 includes an exhaust pipe 341. The top of the exhaust pipe 341 penetrates into the inner cavity of the housing 1. The end of the exhaust pipe 341 away from the housing 1 is connected to a suction shell 342. A fan 343 is fixedly connected between the two sides of the inner cavity of the suction shell 342. A filter is fixedly connected to the top of the suction shell 342. The top of the cooling box 41 is fixedly connected to the second motor 5, the bottom of the second motor 5 is fixedly connected to the cooling box 41, the bottom of the output end of the second motor 5 passes through the cooling box 41 and is fixedly connected to the stirring rod 6, the bottom of the shell 1 is fixedly connected to both sides of the bottom of the shell 1, the support frame 7 is fixedly connected to both sides of the support frame 7, the front side of the shell 1 is fixedly connected to the sliding rod, the two sides of the sliding rod are slidably connected to the sliding sleeve, the top of the sliding sleeve is fixedly connected to the nozzle 33, the top of the tank 2 is connected to the injection pipe, the hot end of the front side of the cooler 42 is fixedly connected to the heat sink, the surface of the tank 2 is fixedly connected to the inner wall of the shell 1 through the partition 8, and the bottom of the left side of the partition 8 is provided with a drainage opening.

[0031] Specifically: the first motor 321 can cooperate with the screw 322 to control the movement of the threaded sleeve 323. The movement of the threaded sleeve 323 can adjust the position of the nozzle 33, so that it can evenly spray cooling water onto the surface of the tank 2. The exhaust pipe 341 can inject air into the shell 1. The exhaust fan 343 can cooperate with the suction shell 342 to deliver external air into the exhaust pipe 341, so that the air on the surface of the tank 2 flows rapidly, accelerating its evaporation rate, and allowing the cooling water to remove heat from the surface of the tank 2 during evaporation. The second motor 5 can control the rotation of the stirring rod 6, which can agitate the water inside the cooling box 41. The stirring process ensures full contact between the stirring head and the cold end of the cooler 42, accelerating the cooling rate. The support frame 7 provides stable support for the shell 1, and the mounting holes allow for the installation and fixation of the support frame 7, preventing displacement of the shell 1. The sliding rod and sliding sleeve limit the movement of the nozzle 33, allowing it to move smoothly left and right and preventing swaying during movement. The injection pipe facilitates the injection of oil and natural gas into the tank 2 for storage. The heat sink increases the heat dissipation effect of the hot end of the cooler 42. The partition 8 separates the shell 1 from the tank 2, increasing the cooling effect on the tank 2. The drain opening facilitates the delivery of cooling water.

[0032] The working principle of this utility model is as follows: the pump body 43 is started to transport the pre-stored cooling water in the cooling box 41 to the nozzle 33 through the hose 44. At the same time, the first motor 321 drives the screw 322 to rotate, and through the threaded engagement with the threaded sleeve 323, it drives the nozzle 33 to move laterally back and forth along the slide rod. The nozzle 33 sprays the cooling water evenly onto the surface of the tank 2, so that the cooling water forms a water film covering the tank 2. The cold end of the cooler 42 continuously cools the water in the cooling box 41, and at the same time, the water inside the shell 1 re-enters the cooling box 41 for circulation. The second motor 5 drives the stirring rod 6 to rotate to maintain a uniform water temperature. When the heat on the surface of the tank 2 causes the water film to evaporate, the exhaust fan 343 draws in external air through the filter screen 344, and pressurizes and delivers it to the inner cavity of the shell 1 through the suction shell 342 and the exhaust pipe 341, so that a high-speed airflow is formed on the surface of the tank 2, which accelerates the evaporation of water vapor and carries away heat. Through the dual effects of water film evaporation heat absorption and forced airflow heat exchange, efficient control of the surface temperature of the tank 2 is achieved.
