Description

Technical Field

[0001] This utility model relates to the field of condensate tank technology, and in particular to an automatic condensate draining device for an online analytical instrument condensate tank. Background Technology

[0002] In the petrochemical industry, various online analytical instruments, gas processing units, and small condensate tanks all require regular condensate drainage. If the condensate is not drained in time, it will affect the normal operation of the equipment and may even cause safety accidents. Therefore, condensate drainage is an important part of ensuring the stable operation of the system. Currently, the condensate drainage methods commonly used in the industry mainly include manual drainage, float-type physical drainage, and peristaltic pump drainage.

[0003] In existing technologies, automatic float-type condensate draining tanks rely on the buoyancy of the condensate to drain it. When the condensate adheres to the float or the sample gas pressure is high, the float may become stuck or sink to the bottom, inevitably leading to air entry or blockage and poor condensate drainage, which can cause the device to shut down. Peristaltic pump condensate drainage requires significant maintenance, as the pump tubing needs to be replaced periodically. Therefore, an automatic condensate draining device for online analytical instrument condensate tanks is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the technical issues in existing technologies where automatic float-type condensate draining tanks rely on the buoyancy of the condensate for draining, and where the float may become stuck or sink to the bottom when the condensate adheres to the float or the sample gas pressure is high, and peristaltic pump draining methods require significant maintenance and periodic replacement of the pump tubing, this application provides an automatic condensate draining device for online analytical instrument condensate tanks.

[0005] This utility model proposes an automatic condensate draining device for an online analytical instrument condensate tank, comprising a frame, with a monitoring mechanism provided on the upper surface of the frame. The monitoring mechanism includes a high liquid level sensor, which monitors the condensate level in real time and outputs a signal.

[0006] The upper surface of the frame is provided with a condensate drainage mechanism, which includes a solenoid valve. The solenoid valve realizes automatic condensate drainage by receiving the signal from the high liquid level sensor.

[0007] Preferably, the monitoring mechanism further includes a liquid collection tank, which is fixedly installed on the upper surface of the frame.

[0008] The above technical solution involves fixing the liquid collection tank to the frame. The liquid collection tank is used to collect the condensate flowing out of the gas separator of the analytical instrument. The material can be selected according to the actual application, such as glass, stainless steel or plexiglass. It is recommended to choose a corrosion-resistant material.

[0009] Preferably, the upper surface of the liquid collection tank is fixedly connected to an inlet pipe, the bottom curved surface of the liquid collection tank is fixedly connected to a condensate drain pipe, and the top curved surface of the liquid collection tank is fixedly connected to an outlet pipe.

[0010] The above technical solution connects the collection tank and the inlet pipe. The inlet pipe can be connected to the equipment that needs to drain condensate via a flexible hose to ensure that the condensate can flow smoothly into the collection tank. A condensate drain pipe is fixedly connected to the bottom of the collection tank to drain the condensate from the collection tank.

[0011] Preferably, the high liquid level sensor is attached to the top curved surface of the liquid collection tank, and a low liquid level sensor is attached to the bottom curved surface of the liquid collection tank. Indicator lights are provided on the outer surfaces of both the high liquid level sensor and the low liquid level sensor.

[0012] The above technical solution involves attaching a low-level sensor to the bottom of the collection tank and fixing it in place. When condensate flows into the collection tank from the inlet pipe, the solenoid valve is in a normally closed, de-energized state, and the solenoid valve indicator light remains off. As the condensate level in the collection tank gradually increases, when the low-level sensor detects the level, its indicator light illuminates, the solenoid valve remains inactive, and the solenoid valve indicator light remains off. A high-level sensor is attached to the top of the collection tank and fixed in place to monitor the condensate level. When the level gradually rises to a set value, it outputs a signal. When the indicator light illuminates, the solenoid valve is energized and opens, its indicator light flashes, triggering the condensate drainage process. When the liquid level drops below the high-level sensor, the high-level sensor indicator light goes out, the solenoid valve remains energized and open, and the solenoid valve indicator light flashes, continuing the condensate drainage. When the liquid level drops below the low-level sensor, the low-level sensor indicator light goes out, the solenoid valve activates, switches to the de-energized closed state, the solenoid valve indicator light goes out, and the condensate drainage ends. Both the high-level and low-level sensors are non-contact sensors, and can be either capacitive or ultrasonic, avoiding direct contact with the condensate.

[0013] Preferably, the condensate drainage mechanism further includes a signal light, which is disposed on the right side surface of the solenoid valve, and the solenoid valve is fixedly mounted on the upper surface of the frame.

[0014] With the above technical solution, an indicator light is installed on the right side of the solenoid valve and electrically connected to it to indicate the working status of the solenoid valve. For example, flashing indicates that condensate is being discharged. The solenoid valve is fixedly installed to the frame. A relay can be set to receive signals from the high liquid level sensor and the low liquid level sensor to control the opening and closing of the solenoid valve. The MY2N series relay can be selected, and a 220V to 24V DC power supply, such as the S-series switching power supply, can be used.

[0015] Preferably, the inlet of the solenoid valve is fixedly connected to the condensate drain pipe via a flexible hose, and is also fixedly connected to the process pipeline.

[0016] Through the above technical solution, the inlet of the solenoid valve is fixedly connected to the condensate drain pipe through a flexible hose, and is also fixedly connected to the process pipeline to control the discharge of condensate. After receiving the signal from the high liquid level sensor, the valve opens to discharge the condensate into the process pipeline.

[0017] Preferably, the output terminals of both the high liquid level sensor and the low liquid level sensor are electrically connected to the control terminal of the solenoid valve via wires.

[0018] With the above technical solution, the output terminals of both the high-level sensor and the low-level sensor are electrically connected to the control terminal of the solenoid valve via wires. When the liquid level in the collection tank reaches the set high level, the high-level sensor outputs a high-level signal, triggering the solenoid valve to open and begin condensation drainage. When the liquid level drops to the set low level, the low-level sensor outputs a low-level signal, triggering the solenoid valve to close and stop condensation drainage.

[0019] The beneficial effects of this utility model are as follows: 1. By setting up a monitoring mechanism, the condensate level is monitored in real time and a signal is output. The collection tank is used to collect the condensate flowing out of the gas separator of the analytical instrument. The inlet pipe can be connected to the equipment that needs to drain condensate through a hose to ensure that the condensate can flow smoothly into the collection tank. The drain pipe is used to drain the condensate from the collection tank. The high liquid level sensor is attached to the top of the collection tank to monitor the liquid level height of the condensate in the collection tank. When the liquid level gradually rises to the set value, a signal is output and the indicator light on it lights up. When the liquid level is drained to below the low liquid level sensor, the indicator light of the low liquid level sensor goes out, the solenoid valve is activated, switching to the power-off closed state, the solenoid valve signal light goes out, and the condensation draining ends. This solves the technical problem in the existing technology that the automatic float drain tank must rely on the buoyancy of the condensate to drain condensate. When the condensate sticks to the float or the sample gas pressure is high, it will force the float to float or sink to the bottom. The peristaltic pump condensation draining method has a large maintenance load and requires the pump pipe to be replaced regularly.

[0020] 2. By setting up a condensate drainage mechanism, automatic condensate drainage is achieved. An indicator light is located on the right side of the solenoid valve and electrically connected to it to indicate the working status of the solenoid valve. For example, flashing indicates that condensate drainage is in progress. The inlet of the solenoid valve is fixedly connected to the condensate drainage pipe through a flexible hose and is also fixedly connected to the process pipeline to control the condensate drainage. After receiving a signal from the high liquid level sensor, the valve opens to drain the condensate into the process pipeline. When the liquid level in the collection tank reaches the set high level, the high liquid level sensor outputs a high-level signal, triggering the solenoid valve to open and start condensate drainage. When the liquid level drops to the set low level, the low liquid level sensor outputs a low-level signal, triggering the solenoid valve to close and stop condensate drainage. This solves the technical problems in the existing technology where the automatic float condensate drainage tank must rely on the buoyancy of the condensate to drain condensate. When the condensate adheres to the float or the sample gas pressure is high, the float will be forced to remain suspended or sink to the bottom. The peristaltic pump condensate drainage method requires a large amount of maintenance and the pump pipe needs to be replaced regularly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-13 An automatic condensate draining device for an online analytical instrument condensate tank includes a frame 1. A monitoring mechanism is provided on the upper surface of the frame 1. The monitoring mechanism includes a high liquid level sensor 4, which monitors the condensate level in real time and outputs a signal.

[0025] To collect the condensate flowing out of the gas separator of the analytical instrument, the monitoring mechanism also includes a collection tank 2, which is fixedly installed on the upper surface of the frame 1. The collection tank 2 is fixed to the frame 1 and is used to collect the condensate flowing out of the gas separator of the analytical instrument. The material can be selected according to the actual application, such as glass, stainless steel or plexiglass. It is recommended to choose a corrosion-resistant material.

[0026] To discharge the condensate from the collection tank 2, an inlet pipe 3 is fixedly connected to the upper surface of the collection tank 2, a condensate drain pipe 31 is fixedly connected to the bottom curved surface of the collection tank 2, and an outlet pipe is fixedly connected to the top curved surface of the collection tank 2. The collection tank 2 is fixedly connected to the inlet pipe 3, and the inlet pipe 3 can be connected to the equipment that needs to drain condensate through a flexible hose to ensure that the condensate can flow smoothly into the collection tank 2. The condensate drain pipe 31 is fixedly connected to the bottom of the collection tank 2 for discharging the condensate from the collection tank 2.

[0027] To monitor the condensate level in the collection tank 2, a high-level sensor 4 is attached to the top curved surface of the collection tank 2, and a low-level sensor 41 is attached to the bottom curved surface of the collection tank 2. Indicator lights 42 are installed on the outer surfaces of both the high-level and low-level sensors 41. The low-level sensor 41 is fixed to the bottom of the collection tank 2. When condensate flows into the collection tank 2 from the inlet pipe 3, the solenoid valve 51 is normally closed and de-energized, and the indicator light 5 of the solenoid valve 51 is off. As the condensate level in the collection tank 2 gradually increases, when the low-level sensor 41 detects the level, its indicator light 42 illuminates, the solenoid valve 51 remains inactive, and its indicator light 5 is off. The high-level sensor 4 is attached to the top of the collection tank 2, and the low-level sensor 41 is fixed to the bottom curved surface of the collection tank 2. Fixed, used to monitor the liquid level of condensate in collection tank 2. When the liquid level gradually rises to the set value, it outputs a signal, the indicator light 42 on it lights up, the solenoid valve 51 is energized and opens, the indicator light 5 on it flashes, triggering the condensate drainage operation. When the liquid level is discharged below the high liquid level sensor 4, the indicator light 42 of the high liquid level sensor 4 goes out, the solenoid valve 51 remains energized and open, the indicator light 5 on the solenoid valve 51 flashes, and the condensate drainage continues. When the liquid level is discharged below the low liquid level sensor 41, the indicator light 42 of the low liquid level sensor 41 goes out, the solenoid valve 51 is activated, switches to the de-energized and closed state, the indicator light 5 on the solenoid valve 51 goes out, and the condensate drainage ends. Both the high liquid level sensor 4 and the low liquid level sensor 41 are non-contact sensors, which can be capacitive or ultrasonic, avoiding direct contact with the condensate.

[0028] By setting up a monitoring mechanism, the condensate level is monitored in real time and a signal is output. The collection tank 2 is used to collect the condensate flowing out of the gas separator of the analytical instrument. The inlet pipe 3 can be connected to the equipment that needs to drain condensate through a hose to ensure that the condensate can flow smoothly into the collection tank 2. The drain pipe 31 is used to drain the condensate from the collection tank 2. The high liquid level sensor 4 is attached to the top of the collection tank 2 to monitor the liquid level height of the condensate in the collection tank 2. When the liquid level gradually rises to the set value, a signal is output and the indicator light 42 on it lights up. When the liquid level is drained to below the low liquid level sensor 41, the indicator light 42 of the low liquid level sensor 41 goes out, the solenoid valve 51 is activated, switching to the power-off closed state, the indicator light 5 of the solenoid valve 51 goes out, and the condensation is finished. This solves the technical problem in the existing technology that the automatic float drain tank must rely on the buoyancy of the condensate to drain condensate. When the condensate sticks to the float or the sample gas pressure is high, the float will be forced to float or sink to the bottom. The peristaltic pump condensation method has a large maintenance load and requires the pump pipe to be replaced regularly.

[0029] In order to achieve automatic discharge of condensate, a condensate discharge mechanism is provided on the upper surface of the frame 1. The condensate discharge mechanism includes a solenoid valve 51, which realizes automatic discharge of condensate by receiving the signal from the high liquid level sensor 4.

[0030] To indicate the working status of the solenoid valve 51, the condensate drainage mechanism also includes an indicator light 5. The indicator light 5 is located on the right side surface of the solenoid valve 51, which is fixedly mounted on the upper surface of the frame 1. The indicator light 5 is located on the right side of the solenoid valve 51 and electrically connected to it to indicate the working status of the solenoid valve 51. For example, flashing indicates that condensate is being drained. The solenoid valve 51 is fixedly mounted to the frame 1. A relay can be installed to receive signals from the high liquid level sensor 4 and the low liquid level sensor 41 and control the opening and closing of the solenoid valve 51. A MY2N series relay can be selected, and a 220V to 24V DC power supply, such as an S-series switching power supply, can be used.

[0031] To control the discharge of condensate, the inlet of solenoid valve 51 is fixedly connected to condensate drain pipe 31 via a flexible hose and is also fixedly connected to the process pipeline. The solenoid valve 51 controls the discharge of condensate. After receiving the signal from high liquid level sensor 4, it opens to discharge condensate into the process pipeline.

[0032] To control the discharge of condensate, the outputs of both the high-level sensor 4 and the low-level sensor 41 are electrically connected to the control terminal of the solenoid valve 51 via wires. When the liquid level in the collection tank 2 reaches the set high level, the high-level sensor 4 outputs a high-level signal, triggering the solenoid valve 51 to open and begin condensate discharge. When the liquid level drops to the set low level, the low-level sensor 41 outputs a low-level signal, triggering the solenoid valve 51 to close and stop condensate discharge.

[0033] By setting up a condensate drainage mechanism, automatic condensate drainage is achieved. The indicator light 5 is located on the right side of the solenoid valve 51 and is electrically connected to it to indicate the working status of the solenoid valve 51. For example, flashing indicates that condensate drainage is in progress. The inlet of the solenoid valve 51 is fixedly connected to the condensate drainage pipe 31 through a flexible hose and is also fixedly connected to the process pipeline to control the condensate drainage. After receiving the signal from the high liquid level sensor 4, it opens to drain the condensate into the process pipeline. When the liquid level in the collection tank 2 reaches the set high level, the high liquid level sensor 4 outputs a high-level signal, triggering the solenoid valve 51 to open and start condensate drainage. When the liquid level drops to the set low level, the low liquid level sensor 41 outputs a low-level signal, triggering the solenoid valve 51 to close and stop condensate drainage. This solves the technical problem in the prior art where the automatic float condensate drainage tank must rely on the buoyancy of the condensate to drain the condensate. When the condensate adheres to the float or the sample gas pressure is high, the float will be forced to float or sink to the bottom. The peristaltic pump condensate drainage method requires a large amount of maintenance and the pump pipe needs to be replaced regularly.

[0034] Working principle: When there is no condensate in the collection tank 2 or the liquid level is lower than the low liquid level sensor 41, the indicator lights 42 of both the high liquid level sensor 4 and the low liquid level sensor 41 are off, the solenoid valve 51 is in the de-energized normally closed state, and the indicator light 5 of the solenoid valve 51 is not lit. The condensate flows from upstream equipment, such as a gas-liquid separator, into the collection tank 2 through the inlet pipe 3. The liquid level gradually rises. When it reaches the detection position of the low-level sensor 41, the sensor detects the liquid level, its indicator light 42 illuminates, the solenoid valve 51 remains closed, and the indicator light 5 on the solenoid valve 51 remains off. The liquid level continues to rise. When it reaches the detection position of the high-level sensor 4, the sensor detects the liquid level, its indicator light 42 illuminates, and the high-level sensor 4 outputs a high-level signal, which is transmitted to the solenoid valve 51 via a wire or relay. The solenoid valve 51 is energized and opens, and the indicator light 5 on the solenoid valve 51 begins to flash. When the condensate drainage process begins, the condensate is discharged into the process pipeline through the condensate drain pipe 31 and solenoid valve 51. The liquid level gradually decreases. When it falls below the detection position of the high liquid level sensor 4, the indicator light 42 of the high liquid level sensor 4 goes out, the solenoid valve 51 remains energized and open, and the indicator light 5 of the solenoid valve 51 continues to flash. The condensate drainage continues, and the liquid level continues to decrease. When it falls below the detection position of the low liquid level sensor 41, the indicator light 42 of the low liquid level sensor 41 goes out, the low liquid level sensor 41 outputs a low-level signal, which is transmitted to the solenoid valve 51 through a wire or relay. The solenoid valve 51 is de-energized and closes, the indicator light 5 of the solenoid valve 51 goes out, and the condensate drainage ends. The above process is automatically repeated, ensuring that the liquid level in the collection tank 2 is always within the set range without manual intervention; Control logic: The high liquid level sensor 4 outputs a high-level signal, triggering the solenoid valve 51 to open; the low liquid level sensor 41 outputs a low-level signal, triggering the solenoid valve 51 to close. Relays are used to amplify sensor signals or implement more complex control logic to improve system reliability, and can be installed as needed. A 220V to 24V DC power supply is used to provide stable power to the sensor, solenoid valve 51 and indicator light 5; Routinely check whether the high level sensor 4 and low level sensor 41 are firmly attached to prevent loosening or displacement, observe whether the indicator light 42 is working properly to ensure accurate signal output, check whether the solenoid valve 51 switches smoothly without jamming, observe whether the indicator light 5 of the solenoid valve 51 displays the working status normally, check whether the hose connection is firm and without leakage or blockage, and ensure that the condensate drain pipe 31 and process pipeline are unobstructed. Regularly clean the surfaces of the high-level sensor 4 and the low-level sensor 41 to prevent dust or dirt from affecting the detection accuracy. Non-contact sensors do not need to be disassembled; they can be wiped directly. Regularly check the sealing performance of the solenoid valve 51, replace aged or damaged seals, and clean the inside of the solenoid valve 51 to prevent impurities from accumulating and affecting its operation. Check whether the relay contacts are normal, without oxidation or burning, and test whether the relay switching action is sensitive. If indicator light 42 is not lit or the signal is abnormal, check the sensor power supply and connection lines, and replace the damaged sensor; if solenoid valve 51 cannot be opened or closed, check the control signal and power supply, and clean or replace the stuck solenoid valve 51; if the condensate is not drained properly, check if the hose is bent or blocked, and clean or replace the blocked pipe. Each component can be disassembled and replaced independently for easy maintenance. in Figure 7 The NPN output drives a small relay. When the coil current is ≤100mA, the working principle is as follows: When the black wire is suspended, it is a normally open output: when liquid is sensed, the transistor is turned on and closed, and the relay is energized and engaged; when no liquid is sensed, the transistor is turned off and disconnected, and the relay is de-energized and not engaged. When the black wire is grounded, i.e. connected to the negative terminal of the power supply (0V), it is a normally closed output: when liquid is sensed, the transistor is cut off and the relay is de-energized and does not engage; when no liquid is sensed, the transistor is turned on and closed, and the relay is energized and engages. The electronic devices, their power supply methods, and control methods described in this article are all existing technologies with mature applications. Therefore, they will only be briefly explained here without further elaboration.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
