Abstract
Description
Technical Field
[0001] This invention relates to the field of flare storage tank technology, and specifically to a self-regulating antifreeze device for liquid phase temperature in flare storage tanks. Background Technology
[0002] In industrial production processes such as petrochemicals and coal chemicals, flare systems serve as crucial facilities for ensuring the safe operation of equipment. They play a critical role in handling combustible gases emitted under abnormal operating conditions and emergency venting gases in case of accidents. When the liquid phase thermometer of the storage tank is below 5°C, it is necessary to manually open the steam tracing valve to heat the liquid and prevent it from freezing. During winter operation, employees need to frequently conduct inspections and operate the steam valve, which consumes a lot of manpower and increases labor costs. Furthermore, manual temperature observation and valve operation during winter operation may lead to freezing of the liquid or damage to the equipment if monitoring and operation are not done properly or in a timely manner.
[0003] The prior art disclosure number "CN222123187U" discloses "a liquid separator for a flare system", which has the characteristics of simple structure, reasonable design, and heating and heat preservation of liquid phase as much as possible under the premise of energy saving, so as to reduce subsequent liquid phase processing and ensure stable operation of the liquid separator.
[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist:
[0005] During use, the insulation and heating structure only heats the outside of the storage tank through a steam pipe, which takes a long time. Furthermore, although the steam pipe is a serpentine pipe, it can only heat the area near the steam pipe and cannot heat the entire inside of the storage tank. Summary of the Invention
[0006] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the heating speed of the liquid storage tank is too slow and that only the area near the steam pipe can be heated during the heating process. To this end, we propose a self-controlled antifreeze device for liquid phase temperature of flare storage tank.
[0007] To achieve the above objectives, this application adopts the following technical solution: a self-regulating antifreeze device for liquid phase temperature of a flare storage tank, comprising a storage tank body: a support leg is connected to the top of the storage tank body, a protective shell is connected to the top of the support leg, a drive mechanism is provided inside the protective shell, a heating mechanism is provided below the drive mechanism, a connecting pipe is provided above the heating mechanism, a steam valve is connected to the center of the connecting pipe, a sensor is also provided above the storage tank body, and a steam pipe is also connected below the connecting pipe.
[0008] Preferably, the drive mechanism includes a first gear, a second gear, a first rubber layer, a second rubber layer, a horizontal plate, and a vertical plate. A motor is also connected above the first gear, and the motor is located inside the protective shell. The motor drives the first gear to rotate, enabling the equipment to operate automatically.
[0009] Preferably, the first gear and the second gear are connected by meshing, the second gear and the steam pipe are integrated into a rotating structure, and the connection between the steam pipe and the storage tank body is provided with sealing rubber. By using the cooperation of the first gear and the second gear, the steam pipe can rotate slowly.
[0010] Preferably, the first rubber layer is located on the outside of the steam pipe, the inner diameter of the steam pipe is larger than the diameter of the connecting pipe, and a second rubber layer is connected to the outside of the connecting pipe. The first rubber layer and the second rubber layer cooperate to seal the connection between the steam pipe and the connecting pipe during rotation.
[0011] Preferably, the horizontal plate and the steam pipe are installed as an integral part, the horizontal plate and the vertical plate form an inverted structure, and the vertical plate and the connecting pipe are installed as an integral part, using the inverted structure to form a secondary seal, further ensuring the steam sealing performance.
[0012] Preferably, the heating mechanism includes an automatic valve, a circulation port, and a stirring rod. The automatic valve is located at the bottom of the steam pipe and automatically opens the steam pipe to discharge condensate.
[0013] Preferably, the circulation ports are evenly and equidistantly distributed on both sides of the steam pipe, and the two sides of the steam pipe are also connected to stirring rods. The stirring rods are shaped with the outer side higher than the inner side, and the stirring rods are used to stir the steam, increase the steam contact surface, and improve the heating efficiency.
[0014] Preferably, a steam valve is also connected above the connecting pipe. The connecting pipe and the protective shell are installed as an integral part. The protective shell is installed as an integral part of the storage tank body through support legs. The steam valve automatically opens the connecting pipe, allowing steam to enter the interior of the connecting pipe.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] This invention features high heating efficiency and a wide heating range: by incorporating a stirring rod that works in conjunction with a steam pipe, the steam pipe drives the stirring rod to rotate during use, thus stirring the inside of the storage tank. This increases the contact area of the steam inside the stirring rod, achieving higher heating efficiency, and also prevents condensation and freezing through stirring, thereby enabling rapid heating.
[0017] In this invention, heating is performed automatically without manual operation: a sensor is installed above the main body of the storage tank. When the temperature reaches a critical value, the sensor drives the steam valve and motor to open through the controller, causing the steam pipe to rotate automatically and steam to be automatically discharged for heating. When the temperature rises to the critical value, the steam valve closes and the heating operation stops. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a technical solution: a self-controlled antifreeze device for liquid phase temperature of a flare storage tank, including a storage tank body 1; a support leg 7 is connected to the top of the storage tank body 1, a protective shell 4 is connected to the top of the support leg 7, a drive mechanism 2 is arranged inside the protective shell 4, a heating mechanism 3 is arranged below the drive mechanism 2, a connecting pipe 5 is arranged above the heating mechanism 3, a steam valve 8 is connected to the center of the connecting pipe 5, a sensor 6 is also arranged above the storage tank body 1, and a steam pipe 9 is also connected below the connecting pipe 5.
[0026] Reference Figure 2 and Figure 3 As shown in this embodiment: the drive mechanism 2 includes a first gear 201, a second gear 202, a first rubber layer 203, a second rubber layer 204, a horizontal plate 205, and a vertical plate 206. A motor is also connected above the first gear 201, and the motor is located inside the protective shell 4. The motor drives the first gear 201 to rotate, so that the equipment can operate automatically. The first gear 201 and the second gear 202 are connected by meshing. The second gear 202 and the steam pipe 9 have an integrated rotating structure. The connection between the steam pipe 9 and the storage tank body 1 is provided with sealing rubber. By cooperating with the first gear 201 and the second gear 202, the steam pipe 9 can rotate slowly.
[0027] Reference Figure 2 , Figure 3 and Figure 4 As shown in this embodiment: the first rubber layer 203 is located on the outside of the steam pipe 9, the inner diameter of the steam pipe 9 is larger than the diameter of the connecting pipe 5, and the outside of the connecting pipe 5 is connected to the second rubber layer 204. Through the cooperation of the first rubber layer 203 and the second rubber layer 204, the connection between the steam pipe 9 and the connecting pipe 5 is sealed during the rotation. The horizontal plate 205 is installed integrally with the steam pipe 9, and the horizontal plate 205 and the vertical plate 206 form an inverted structure. The vertical plate 206 is installed integrally with the connecting pipe 5. The inverted structure forms a secondary seal, which further ensures the steam sealing performance.
[0028] Reference Figure 2 As shown in this embodiment, the heating mechanism 3 includes an automatic valve 301, a circulation port 302, and a stirring rod 303. The automatic valve 301 is located at the bottom of the steam pipe 9. The automatic valve 301 automatically opens the steam pipe 9 to discharge condensate. The circulation ports 302 are evenly distributed on both sides of the steam pipe 9. The stirring rods 303 are also connected to both sides of the steam pipe 9. The stirring rods 303 are shaped with the outer side higher than the inner side. The stirring rods 303 are used to stir the steam, increase the steam contact surface, and improve the heating efficiency.
[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment: a steam valve 8 is also connected above the connecting pipe 5. The connecting pipe 5 and the protective shell 4 are installed as an integral unit. The protective shell 4 is installed as an integral unit with the storage tank body 1 through the support leg 7. The connecting pipe 5 is automatically opened by the steam valve 8, so that steam enters the interior of the connecting pipe 5.
[0030] Working principle: First, during use, sensor 6 monitors the temperature of the tank body 1. When the temperature reaches the critical value, sensor 6 transmits the temperature signal to the PLC controller. The PLC controller opens the steam valve 8, allowing steam to enter the steam pipe 9 through the connecting pipe 5. At the same time, the PLC controller turns on the motor, which drives the first gear 201 to rotate. The first gear 201 meshes with the second gear 202, causing the second gear 202 to drive the steam pipe 9 at its center to rotate slowly. At this time, the steam enters the inner side of the stirring rod 303 through the circulation ports 302 on both sides of the steam pipe 9 for heat exchange. Then, the condensate accumulates along the stirring rod 303 above the automatic valve 301 at the bottom. The automatic valve 301 is a gravity sensing valve. When too much condensate accumulates, it automatically opens to discharge the condensate and then closes.
[0031] As mentioned above, when the temperature rises to the critical value, sensor 6 transmits the temperature signal to the PLC controller, causing the motor to stop working and the steam valve 8 to close. When the steam pipe 9 rotates, it drives the horizontal plate 205 to rotate. The vertical plate 206 above the horizontal plate 205 is in a fixed state, cooperating with the first rubber layer 203 and the second rubber layer 204 to ensure a seal and prevent steam leakage.
[0032] It is important to note that the fact that sensor 6 works with the PLC controller to open and close steam valve 8 is basic information known to those in the field, and will not be elaborated upon here.
[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
