Description

Technical Field

[0001] The utility model relates to the field of petrochemical storage and transportation, in particular to a petrochemical storage and transportation anti-leakage monitoring device. Background Art

[0002] Petrochemical storage and transportation refers to the storage and transportation of petroleum and chemical products from production sites to consumption sites. This process encompasses the collection, refining, storage, and transportation of crude oil, as well as the storage and distribution of refined oil and chemical products. Storage and transportation is a critical component of the petrochemical industry chain, directly impacting energy security and economic profitability. However, improper connection between gasoline storage tanks and the extraction pipes can sometimes lead to gasoline leaks during extraction, resulting in economic losses and safety hazards. Utility Model Content

[0003] In order to overcome the problem that during the process of extracting gasoline from the oil tank, improper connection operation with the oil extraction pipe may sometimes cause gasoline to leak from the connection between the tank and the oil extraction pipe, thereby causing economic losses and safety hazards.

[0004] The technical solution of the utility model is: a petrochemical storage and utilization leakage monitoring device, comprising a leakage detection component, a leakage liquid recovery component, and a liquid inlet component; a leakage liquid recovery component for recovering leaked liquid is provided on one side of the leakage detection component; and a liquid inlet component is provided on the other side of the leakage detection component.

[0005] Preferably, the anti-leakage detection component is used to detect whether the equipment is leaking and to issue an alarm to alert the staff when a leak is detected. The leakage recovery component is used to recover the leaked liquid, and the liquid inlet component is used to add liquid into the equipment.

[0006] Preferably, the leak detection assembly includes a storage tank, a base plate, a bucket surface, a sealing cover, a U-shaped liquid outlet pipe, a sealing ring, a reflux groove, a photoelectric water immersion sensor, and an audible and visual alarm. The base plate is fixedly connected to the upper end of the storage tank, and the upper end surface of the base plate is provided with a bucket surface. When the oil extraction pipe of the extraction equipment is fitted with the clearance between the upper end of the U-shaped liquid outlet pipe and the oil extraction pipe is pressed against the upper end surfaces of the two sealing rings simultaneously, the leaked liquid during the oil extraction process will flow onto the bucket surface and, due to the slope of the bucket surface, will be collected by gravity and flow into the reflux groove. When the liquid collected in the reflux groove submerges the photoelectric water immersion sensor, the photoelectric water immersion sensor activates the audible and visual alarm to sound an alarm, and then causes the electronically controlled valve to open and the liquid pump to operate.

[0007] Preferably, a sealing cover is fixed to the upper end of the bucket surface; a U-shaped liquid outlet pipe penetrating the base plate is fixed to the inside of the base plate; and sealing rings are fixed to the upper ends of the U-shaped liquid outlet pipe and the sealing cover.

[0008] Preferably, a reflux groove is provided on one side of the U-shaped liquid outlet pipe; a photoelectric water immersion sensor embedded in the base plate is provided at the rear end of the reflux groove; an audible and visual alarm is fixed to one side of the storage tank; the photoelectric water immersion sensor is electrically connected to the audible and visual alarm.

[0009] Preferably, the leakage liquid recovery component includes an electric control valve, a liquid pump, a reflux pipe, a buffer tank, a Tesla valve pipe, and a lower buckle cover; one side of the reflux tank is connected to an electric control valve fixed to the base plate; the electric control valve, the liquid pump and the electric control valve are electrically connected to the photoelectric water immersion sensor; one side of the liquid pump is connected to the reflux pipe. When the liquid pump is operating, the liquid gathered in the reflux tank passes through the electric control valve, the liquid pump and the reflux pipe in sequence into the buffer tank. When the liquid level in the storage tank is higher than the buffer tank, the refluxed liquid will be temporarily stored in the buffer tank, and the Tesla valve pipe will prevent the liquid in the storage tank from flowing into the buffer tank. When the liquid level in the storage tank is lower than the buffer tank, the liquid in the buffer tank will flow into the storage tank through the Tesla valve pipe and the lower buckle cover.

[0010] Preferably, one side of the return pipe is connected to a buffer tank fixedly connected to the storage tank; the lower end of the buffer tank is connected to a Tesla valve pipe; the lower end of the Tesla valve pipe is connected to the storage tank; and a lower buckle cover is fixed to one side of the storage tank interior, and the lower buckle cover is connected to the lower end of the Tesla valve pipe. After the liquid in the reflux tank is drained and the photoelectric water immersion sensor is no longer submerged, the liquid pump stops operating and the electronically controlled valve closes to prevent steam from flowing from the return pipe into the reflux tank.

[0011] Preferably, the liquid inlet assembly includes a U-shaped liquid inlet pipe and a sealing cap. The U-shaped liquid inlet pipe is disposed on one side of the base plate and extends through the storage tank. The sealing cap is fitted into the gap at the upper end of the U-shaped liquid inlet pipe. Both the U-shaped liquid outlet pipe and the U-shaped liquid inlet pipe utilize their inherent U-shaped bends to reduce the probability of evaporated gas within the storage tank escaping through the outlet and inlet pipes.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up a leak detection mechanism and a reflux recovery mechanism, the device can immediately issue an alarm when a liquid leak occurs to prompt the staff to carry out maintenance, and recover the leaked liquid in time, thereby reducing safety hazards and economic losses;

[0014] 2. After the oil extraction pipe of the extraction equipment is matched with the upper end clearance of the U-shaped liquid outlet pipe and the oil extraction pipe is pressed against the upper end surfaces of the two sealing rings at the same time, the leaked liquid will flow onto the bucket surface during the oil extraction process and be collected by gravity due to the slope of the bucket surface and flow into the reflux groove. When the liquid collected in the reflux groove submerges the photoelectric water immersion sensor, the photoelectric water immersion sensor will activate the sound and light alarm, and open the electronically controlled valve to operate the liquid pump, thereby reducing safety hazards;

[0015] 3. When the liquid pump is operating, the liquid gathered in the reflux tank passes through the electronically controlled valve, liquid pump and reflux pipe in turn into the buffer tank. When the liquid level in the storage tank is higher than the buffer tank, the refluxed liquid will be temporarily stored in the buffer tank, and the Tesla valve pipe will prevent the liquid in the storage tank from flowing into the buffer tank. When the liquid level in the storage tank is lower than the buffer tank, the liquid in the buffer tank will flow into the storage tank through the Tesla valve pipe and the lower buckle cover, thereby reducing losses.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-2The utility model provides an embodiment: a petrochemical storage and utilization leakage monitoring device, comprising a leakage detection component 1, a leakage liquid recovery component 2, and a liquid inlet component 3; a leakage liquid recovery component 2 for recovering leaked liquid is provided on one side of the leakage detection component 1; a liquid inlet component 3 is provided on the other side of the leakage detection component 1. The leakage detection component 1 is used to detect whether the equipment is leaking and issue an alarm to alert the staff when a leak is detected; the leakage liquid recovery component 2 is used to recover the leaked liquid; and the liquid inlet component 3 is used to add liquid into the equipment. The leakage detection component 1 comprises a storage tank 101, a base plate 102, a bucket surface 103, a sealing cover 104, a U-shaped liquid outlet pipe 105, a sealing ring 106, a reflux groove 107, a photoelectric water immersion sensor 108, and an audible and visual alarm 109; the upper end of the storage tank 101 is fixedly connected to the base plate 102, and the upper end surface of the base plate 102 is provided with a bucket surface 103. After the extraction equipment's oil extraction pipeline is fitted with the clearance between the upper ends of the U-shaped liquid outlet pipe 105 and the pipeline is simultaneously pressed against the upper end surfaces of two sealing rings 106, the leaked liquid during the extraction process will flow onto the bucket surface 103. Due to the slope of the bucket surface 103, it is gathered by gravity and flows into the reflux groove 107. When the liquid gathered in the reflux groove 107 floods the photoelectric water immersion sensor 108, the photoelectric water immersion sensor 108 activates the sound and light alarm 109, sounds an alarm, opens the electric control valve 201, and activates the liquid pump 202. The upper end of the bucket surface 103 is fixedly connected to the sealing cover 104; the interior of the base plate 102 is fixedly connected to the U-shaped liquid outlet pipe 105 that passes through the base plate 102; and the upper ends of the U-shaped liquid outlet pipe 105 and the sealing cover 104 are fixedly connected to the sealing ring 106. A reflux groove 107 is provided on one side of the U-shaped liquid outlet pipe 105; a photoelectric water immersion sensor 108 embedded in the base plate 102 is provided at the rear end of the reflux groove 107; an audible and visual alarm 109 is fixedly connected to one side of the storage tank 101; the photoelectric water immersion sensor 108 is electrically connected to the audible and visual alarm 109.

[0023] See also Figure 3-4In this embodiment, the leakage liquid recovery component 2 includes an electric-controlled valve 201, a liquid pump 202, a reflux pipe 203, a buffer tank 204, a Tesla valve tube 205, and a lower buckle cover 206; one side of the reflux groove 107 is connected to the electric-controlled valve 201 fixedly connected to the base plate 102; one side of the electric-controlled valve 201 is connected to the liquid pump 202, and the liquid pump 202 and the electric-controlled valve 201 are both electrically connected to the photoelectric water immersion sensor 108; one side of the liquid pump 202 is connected to the reflux pipe 203. When liquid pump 202 is operating, the liquid collected in reflux tank 107 passes through electronically controlled valve 201, liquid pump 202, and reflux pipe 203 in sequence and enters buffer tank 204. When the liquid level in storage tank 101 is higher than buffer tank 204, the refluxed liquid is temporarily stored in buffer tank 204, and the Tesla valve pipe 205 prevents the liquid in storage tank 101 from flowing into buffer tank 204. When the liquid level in storage tank 101 is lower than buffer tank 204, the liquid in buffer tank 204 flows into storage tank 101 through Tesla valve pipe 205 and lower buckle cover 206. One side of reflux pipe 203 is connected to buffer tank 204, which is fixed to storage tank 101. The lower end of buffer tank 204 is connected to Tesla valve pipe 205, and the lower end of Tesla valve pipe 205 is connected to storage tank 101. The lower buckle cover 206 is fixed to one side of the interior of storage tank 101 and is connected to the lower end of Tesla valve pipe 205. After the liquid in the reflux tank 107 is drained and the photoelectric water sensor 108 is no longer submerged, the liquid pump 202 stops operating and the electrically controlled valve 201 closes to prevent steam from flowing from the reflux pipe 203 into the reflux tank 107. The liquid inlet assembly 3 includes a U-shaped liquid inlet pipe 301 and a sealing cap 302. The U-shaped liquid inlet pipe 301 is provided on one side of the base plate 102 and extends through the storage tank 101. The sealing cap 302 is fitted into the gap at the upper end of the U-shaped liquid inlet pipe 301. Both the U-shaped liquid outlet pipe 105 and the U-shaped liquid inlet pipe 301, through their inherent U-shaped bend structures, reduce the probability of evaporated gas in the storage tank 101 flowing out of the liquid outlet and inlet pipes.

[0024] During operation, the oil extraction pipe of the extraction equipment is fitted with the upper end clearance of the U-shaped liquid outlet pipe 105, and the oil extraction pipe is pressed against the upper end surfaces of the two sealing rings 106 at the same time. During the oil extraction process, the leaked liquid will flow onto the bucket surface 103 and be collected by gravity due to the slope of the bucket surface 103 and flow into the reflux groove 107. When the liquid collected in the reflux groove 107 submerges the photoelectric water immersion sensor 108, the photoelectric water immersion sensor 108 activates the sound and light alarm 109 to sound an alarm, and opens the electric control valve 201 and activates the liquid pump 202.

[0025] When the liquid pump 202 is operating, the liquid collected in the reflux tank 107 passes through the electronically controlled valve 201, the liquid pump 202 and the reflux pipe 203 in sequence and enters the buffer tank 204. When the liquid level in the storage tank 101 is higher than the buffer tank 204, the refluxed liquid will be temporarily stored in the buffer tank 204 and the Tesla valve tube 205 will prevent the liquid in the storage tank 101 from flowing into the buffer tank 204. When the liquid level in the storage tank 101 is lower than the buffer tank 204, the liquid in the buffer tank 204 will flow into the storage tank 101 through the Tesla valve tube 205 and the lower buckle cover 206.

[0026] After the liquid in the reflux tank 107 is drained and the photoelectric water sensor 108 is no longer submerged, the liquid pump 202 stops operating and the electronically controlled valve 201 is closed to prevent steam from flowing from the reflux pipe 203 into the reflux tank 107 .

[0027] Through the above steps, a leak detection mechanism and a reflux recovery mechanism are set up, so that the device can immediately issue an alarm after a liquid leak occurs to prompt the staff to carry out maintenance, and recover the leaked liquid in time, thereby reducing safety hazards and economic losses.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
