Description

Technical Field

[0001] This utility model relates to the technical field of gas hydrate concentration devices, and more specifically, to a safety monitoring system for a gas hydrate concentration device. Background Technology

[0002] Existing gas hydrate concentration devices utilize the formation of ice crystal-like cage-like structures by gas molecules and water molecules in a solution under certain pressure and temperature. These structures are then removed by mechanical means such as filtration and centrifugation to obtain a concentrated liquid. This technology, which uses low pressure and low temperature concentration, is suitable for the preparation of highly heat-sensitive, high-moisture, and high-sugar liquid materials.

[0003] During operation, gas hydrate concentration devices require the supply of gas to increase the pressure within the device's chamber, bringing it to the required concentration level. To prevent excessive pressure and potential safety hazards, pressure sensors are typically used to monitor pressure changes. However, relying solely on pressure sensors for pressure control is not very safe. If a pressure sensor malfunctions, it cannot accurately and promptly reflect the true pressure within the chamber, potentially leading to accidents. Utility Model Content

[0004] Based on the aforementioned technical problem that controlling gas pressure safety solely through a pressure sensor has low safety, and that if the pressure sensor malfunctions, it will be unable to accurately and promptly reflect the true pressure condition inside the cavity, which can easily lead to accidents, this utility model proposes a safety monitoring system for a gas hydrate concentration device.

[0005] This utility model proposes a safety monitoring system for a gas hydrate concentration device, comprising:

[0006] Concentration equipment;

[0007] A pressure relief subsystem, which is installed inside the concentration equipment, includes a pressure relief pipe that extends through the concentration equipment to its outside.

[0008] A pressure conversion subsystem includes a connecting pipe, which is fixedly connected to a pressure relief pipe; a micro generator is installed inside the connecting pipe, a fan blade is fixedly connected to the shaft end of the micro generator, a fixing sleeve is fixedly connected to the outer wall of the micro generator, a support rod is fixedly connected to the outer wall of the fixing sleeve, and the end of the support rod is fixedly connected to the connecting pipe.

[0009] The monitoring and alarm subsystem includes an alarm light, the alarm light's wiring terminal is fixedly connected to a power cord, and the end of the power cord is connected to a micro generator.

[0010] Preferably, the pressure relief subsystem further includes an installation pipe installed inside the concentration equipment. A pressure relief pipe is fixedly connected to the inner wall of the installation pipe, and a sealing plug is fixedly connected to the inner wall of the installation pipe. Two plugs are slidably connected to the inner wall of the sealing plug, and a sliding rod is fixedly connected to the top of the plugs. A first collar is slidably connected to the inner wall of the installation pipe, and the top of the sliding rod passes through the first collar and is fixedly connected to it. A spring is sleeved on the outer wall of the sliding rod, and the spring is located between the first collar and the second collar. A second collar is fixedly connected to the inner wall of the installation pipe, and the top of the sliding rod passes through the second collar and is slidably connected to it. A limit sleeve is fixedly connected to the upper end of the sliding rod at the second collar.

[0011] Preferably, one end of the spring is fixedly connected to the first collar (13), and the other end of the spring is fixedly connected to the second collar.

[0012] Preferably, an mounting sleeve is fixedly connected to the inner wall of the second ring, and the outer wall of the mounting sleeve is slidably connected to the first ring.

[0013] Preferably, an exhaust nozzle is fixedly connected to the bottom of the mounting pipe, and the bottom of the exhaust nozzle is connected to the gas conveying equipment.

[0014] Preferably, an air inlet pipe is fixedly connected to the top of the mounting pipe, and the gas storage cylinder supplies gas to the concentration equipment through the air inlet pipe. The outer end of the air inlet pipe penetrates the concentration equipment and extends to its outer side, while the inner end of the air inlet pipe extends into the interior of the mounting pipe.

[0015] Preferably, a mounting frame is fixedly connected to the outer wall of the concentration equipment, a support plate is fixedly connected to the top of the mounting frame, a connecting pipe is fixedly connected to the top of the support plate, and the connecting pipe is fixedly connected to the pressure relief pipe.

[0016] Preferably, an exhaust pipe is fixedly connected to the end of the connecting pipe, the end of the exhaust pipe is connected to the gas storage tank, and a one-way valve is installed on the outer wall of the exhaust pipe.

[0017] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0018] 1. Gas is injected into the concentration equipment through the inlet pipe to increase the pressure inside the chamber. The gas enters the chamber through the inlet pipe, the mounting pipe, and the exhaust nozzle. When the pressure inside the chamber reaches the preset value, the pressure inside the chamber acts in reverse on the plug. Under the action of air pressure, the plug slides outward from the sealing plug until the gas inside the chamber is discharged through the pressure relief pipe. This allows for safe control of the air pressure and avoids accidents caused by the pressure sensor failing to accurately and timely reflect the true pressure status inside the chamber.

[0019] 2. The gas discharged through the pressure relief pipe is rapidly ejected into the connecting pipe under pressure. The gas blows the fan blades to rotate, and at this time the micro generator supplies power to the alarm light through the power line. The alarm light then lights up and sounds an alarm.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. In this utility model, unless otherwise expressly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1-4 As shown, a safety monitoring system for a gas hydrate concentration device includes a pressure relief subsystem, a pressure conversion subsystem, and a monitoring and alarm subsystem. The pressure relief subsystem is installed inside the concentration device 2 and includes an installation pipe 4. The concentration device 2 is a gas hydrate concentration device, which is existing technology and will not be described in detail here.

[0027] The mounting pipe 4 is installed inside the concentrator 2. A pressure relief pipe 5 is fixedly connected to the inner wall of the mounting pipe 4. The end of the pressure relief pipe 5 passes through the concentrator 2 and extends to its outer side. The pressure relief pipe 5 can discharge gas exceeding the pressure value from the concentrator 2.

[0028] A sealing plug 12 is fixedly connected to the inner wall of the mounting tube 4. Two plugs 17 are slidably connected to the inner wall of the sealing plug 12. A sliding rod 16 is fixedly connected to the top of the plug 17. A first collar 13 is slidably connected to the inner wall of the mounting tube 4. The top of the sliding rod 16 passes through the first collar 13 and is fixedly connected to it. A spring 18 is sleeved on the outer wall of the sliding rod 16. The spring 18 is located between the first collar 13 and the second collar 14. One end of the spring 18 is fixedly connected to the first collar 13, and the other end of the spring 18 is fixedly connected to the second collar 14. A second collar 14 is fixedly connected to the inner wall of the mounting tube 4. The top of the sliding rod 16 passes through the second collar 14 and is slidably connected to it. A limit sleeve 19 is fixedly connected to the upper end of the sliding rod 16 at the second collar 14.

[0029] The elastic force of spring 18 can be set according to the pressure value set in the cavity. This pressure value is not the limit pressure value in the cavity, but the pressure value required to generate concentrate in the cavity. When the pressure value in the cavity exceeds the safe range, spring 18 is compressed, causing plug 17 to move slowly from the sealing plug 12. As the pressure value gradually increases, plug 17 is disengaged from the sealing plug 12, thus achieving the purpose of pressure relief.

[0030] The inner wall of the second ring 14 is fixedly connected to the mounting sleeve 15, and the outer wall of the mounting sleeve 15 is slidably connected to the first ring 13.

[0031] The mounting sleeve 15 can seal the cavity between the first sleeve ring 13 and the second sleeve ring 14 of the mounting tube 4, preventing gas in the cavity from entering the cavity and causing poor exhaust. Therefore, the mounting sleeve 15 facilitates the smooth exhaust of gas from the cavity.

[0032] In some embodiments, the mounting sleeve 15 located at one end of the pressure relief pipe 5 can be configured as a horn shape, the tip of the horn can be connected to the pressure relief pipe 5, and the end of the air intake pipe 3 passes through the horn end of the mounting sleeve 15 and extends below it, so that gas can be quickly discharged into the pressure relief pipe 5 through the horn end of the mounting sleeve 15.

[0033] The bottom of the mounting pipe 4 is fixedly connected to the exhaust nozzle 11, and the bottom of the exhaust nozzle 11 is connected to the gas inside the concentration device 2.

[0034] In some embodiments, the mounting tube 4 located in one end cavity of the exhaust nozzle 11 can be configured as a cone shape, which facilitates the rapid discharge of gas in the intake pipe 3 into the exhaust nozzle 11 and reduces the resistance during gas flow.

[0035] An air inlet pipe 3 is fixedly connected to the top of the mounting pipe 4. The gas storage cylinder supplies gas to the concentration equipment 2 through the air inlet pipe 3. The outer end of the air inlet pipe 3 passes through the concentration equipment 2 and extends to its outer side, while the inner end of the air inlet pipe 3 extends into the interior of the mounting pipe 4.

[0036] The outer wall of the concentration equipment 2 is fixedly connected to the mounting bracket 1, the top of the mounting bracket 1 is fixedly connected to the support plate 7, the top of the support plate 7 is fixedly connected to the connecting pipe 6, and the connecting pipe 6 is fixedly connected to the pressure relief pipe 5.

[0037] In the above embodiments, the mounting pipe 4 and its internal structure together constitute the pressure relief subsystem of this application.

[0038] A micro generator 20 is installed inside the connecting pipe 6. A fan blade 23 is fixedly connected to the shaft end of the micro generator 20. A fixing sleeve 21 is fixedly connected to the outer wall of the micro generator 20. A support rod 22 is fixedly connected to the outer wall of the fixing sleeve 21. The end of the support rod 22 is fixedly connected to the connecting pipe 6. An alarm light 8 is fixedly connected to the outer wall of the connecting pipe 6. A power line 24 is fixedly connected to the terminal of the alarm light 8, and the end of the power line 24 is connected to the micro generator 20. Gas discharged through the pressure relief pipe 5 is rapidly ejected into the connecting pipe 6 under pressure, causing the fan blade 23 to rotate. At this time, the micro generator 20 supplies power to the alarm light 8 through the power line 24, causing the alarm light 8 to illuminate and sound an alarm. In this application, the connecting pipe 6 and its internal structure together constitute a pressure conversion subsystem, and the alarm light 8 and power line 24 constitute a monitoring and alarm subsystem.

[0039] The alarm light 8 and the micro generator 20 are existing technologies and will not be discussed in detail here. The alarm light 8 can convert the power output from the micro generator 20 into a suitable voltage through a voltage regulator for use.

[0040] An exhaust pipe 9 is fixedly connected to the end of the connecting pipe 6. The end of the exhaust pipe 9 is connected to the gas storage tank. A one-way valve 10 is installed on the outer wall of the exhaust pipe 9.

[0041] Working principle: Gas is injected into the concentration device 2 through the air inlet pipe 3 to increase the pressure inside the chamber. The gas enters the chamber through the air inlet pipe 3, the mounting pipe 4 and the exhaust nozzle 11. When the pressure inside the chamber reaches the preset value, the pressure inside the chamber acts in reverse on the plug 17. Under the action of air pressure, the plug 17 slides outward of the sealing plug 12 until the gas inside the chamber is discharged through the pressure relief pipe 5. This allows for safe control of the air pressure and avoids accidents caused by the pressure sensor failing to accurately and timely reflect the real pressure inside the chamber.

[0042] When the air pressure inside the cavity reaches a safe value, the plug 17 will press against the sealing plug 12 again under the elastic force of the spring 18 to prevent gas leakage from the cavity.

[0043] The gas discharged through the pressure relief pipe 5 is rapidly ejected into the connecting pipe 6 under pressure. The gas blows the fan blade 23 to rotate. At this time, the micro generator 20 supplies power to the alarm light 8 through the power line 24. The alarm light 8 then lights up and sounds an alarm.

[0044] The gas enters the exhaust pipe 9 through the connecting pipe 6 and passes through the one-way valve 10 into the external gas collection tank for temporary storage.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
