Description

Technical Field

[0001] This utility model belongs to the field of drainage device technology, specifically relating to a multi-channel real-time monitoring and alarm device for gas drainage devices. Background Technology

[0002] Gas drainers are auxiliary devices primarily used to collect and drain condensate and impurities from gas pipelines, ensuring unobstructed gas flow. Whether it's coke oven gas, blast furnace gas, or converter gas, the collected condensate contains a certain amount of chemical components or other particulate impurities. This is especially true for coke oven gas drainers, where the condensate contains large amounts of tar, naphthalene, benzene, phenol, and other chemicals. After the condensate is discharged, as the temperature drops, some of these chemicals precipitate and adhere to the pipeline or the bottom of the drainer, easily causing blockages at the bottom of the drainer, the downpipe, and the overflow pipe, especially during the cold winter months. In northern regions, insulation measures must be taken for gas drainers in winter to prevent significant losses due to freezing and blockage.

[0003] Utility model patent CN118912397A discloses a real-time monitoring and alarm device and method for a gas drainer. This alarm device can monitor the liquid levels inside the drainer, in the drain pipe, and in the overflow pipe in real time to prevent accidents such as "untimely detection of drainer blockage affecting pipeline gas transportation, low water level causing gas leakage, untimely detection of gas rupture causing poisoning, and overflow of condensate due to overflow pipe blockage." However, in the cold winter season, if the drainer's insulation measures malfunction, the alarm device can only detect and trigger an alarm after the drainer has frozen and become blocked.

[0004] Therefore, designing an intelligent alarm device that can monitor the temperature and liquid level of the drainer in real time and can issue separate alarms for different monitoring points is an urgent technical problem to be solved. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model discloses a multi-channel real-time monitoring and alarm device for gas drainers, specifically employing the following technical solution:

[0006] A multi-channel real-time monitoring and alarm device for a gas drainer includes an overflow pipe temperature alarm device, a heat tracing pipe temperature alarm device, a drain pipe blockage alarm device, an overflow pipe blockage alarm device, a water seal level alarm device, and an alarm system.

[0007] The gas drainer includes a gas pipeline, a drainer body, a downpipe, an overflow pipe, and a heat tracing pipe. The gas pipeline is located above the drainer body. The upper end of the drainer body is provided with an air inlet and an overflow outlet. The downpipe is connected to the gas pipeline and is inserted into the drainer body through the air inlet. The overflow pipe is connected to the overflow outlet. The heat tracing pipe is located on the outer wall of the drainer body.

[0008] The overflow pipe temperature alarm device is located at the overflow port inside the drain body; the heat tracing pipe temperature alarm device is located on the heat tracing pipe; the downpipe blockage alarm device is located on the downpipe; the overflow pipe blockage alarm device is located on the overflow pipe; and the water seal level alarm device is located inside the drain body. The alarm system is connected to the overflow pipe temperature alarm device, the heat tracing pipe temperature alarm device, the downpipe blockage alarm device, the overflow pipe blockage alarm device, and the water seal level alarm device, respectively.

[0009] The overflow pipe temperature alarm device is used to detect the temperature at the overflow pipe inlet to check whether the drainer's insulation system is operating normally. The temperature at the overflow pipe inlet can be used to detect the drainer's temperature, preventing freezing due to abnormal heating or insulation, or pressure fluctuations in the pipeline caused by prolonged blockage of the gas pipeline drain pipe. The heat tracing pipe temperature alarm device is used to detect the temperature of the heat tracing pipe.

[0010] Furthermore, the overflow pipe temperature alarm device includes a sealed corrosion-resistant isolator, a wire, and a heat-conducting container located within the corrosion-resistant isolator. The heat-conducting container includes a heat-conducting cavity and an insulating cover connected to the heat-conducting cavity. A first temperature control switch is provided within the heat-conducting cavity, and a pressure-guiding port is provided on the insulating cover. The pressure-guiding port extends out of the corrosion-resistant isolator, and the wire passes through the corrosion-resistant isolator and the insulating cover to connect with the first temperature control switch. The pressure-guiding port is used to prevent abnormal pressure inside the heat-conducting container from affecting the sensitivity of the first temperature control switch.

[0011] Furthermore, the upper end of the drain body is provided with an installation hole, the anti-corrosion isolator is inserted into the drain body through the installation hole, and the wire extends to the outside of the drain body.

[0012] Furthermore, the heat tracing pipe temperature alarm device includes a sealed box, a temperature sensing wire located outside the sealed box, and a second temperature control switch. The sealed box is provided with a pipe opening and a temperature sensor, and the temperature sensor is connected to the second temperature control switch through the temperature sensing wire.

[0013] Furthermore, the alarm system includes a controller, a transmitter, and several client devices. The controller is equipped with a first signal interface connected to the overflow pipe temperature alarm device, a second signal interface connected to the heat tracing pipe temperature alarm device, a third signal interface connected to the downpipe blockage alarm device, a fourth signal interface connected to the overflow pipe blockage alarm device, and a fifth signal interface connected to the water seal level alarm device. The first, second, third, fourth, and fifth signal interfaces are connected in parallel. The controller is connected to the transmitter, and the transmitter is connected to several client devices.

[0014] Furthermore, the controller is equipped with a maintenance switch, which is signal-connected to the controller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model's multi-channel real-time monitoring and alarm device for gas drainers can monitor the overflow pipe inlet temperature, heat tracing pipe temperature, downpipe liquid level, overflow pipe liquid level, and water seal liquid level inside the drainer body in real time. It can also provide accurate alarms for fault points, ultimately achieving unmanned, wireless, intelligent, and automatic inspection of gas drainers.

[0017] This utility model can be uniformly promoted and applied to all gas drainers managed by the same production plant, which can greatly reduce the number of personnel required to operate and inspect gas equipment and facilities, promptly detect problems that occur during the operation of gas drainers, and lay the foundation for optimizing the company's human resources.

[0028] The overflow pipe temperature alarm device 6 is located at the overflow port 202 inside the drain body; the heat tracing pipe temperature alarm device 7 is located on the heat tracing pipe 5; the downpipe blockage alarm device 8 is located on the downpipe 3; the overflow pipe blockage alarm device 9 is located on the overflow pipe 4; and the water seal level alarm device 10 is located inside the drain body 2.

[0029] The overflow pipe temperature alarm device 6 includes a sealed corrosion-resistant isolator 601, a wire 605, and a heat-conducting container disposed within the corrosion-resistant isolator 601. The heat-conducting container includes a heat-conducting cavity 602 and an insulation cover 603 connected to the heat-conducting cavity 602.

A bracket (not shown in the figure) for fixing the first temperature control switch 604 is provided on the heat-conducting cavity 602 or the insulation cover 603. A pressure-guiding port 606 is provided on the insulation cover 603, and the pressure-guiding port 606 extends out of the corrosion-resistant isolator 601. The wire 605 passes through the corrosion-resistant isolator 601 and the insulation cover 603 and is connected to the first temperature control switch 604. The heat-conducting container is connected to the outside through the pressure-guiding port 606 to prevent abnormal pressure inside the heat-conducting container from affecting the sensitivity of the first temperature control switch 604. The heat-conducting medium inside the heat-conducting cavity 602 is air.

[0030] The heat tracing pipe temperature alarm device 7 includes a sealed box 701, a temperature sensing wire 702 located outside the sealed box 701, and a second temperature control switch 703. The sealed box 701 has a pipe opening 704 and a temperature sensor 705. The pipe opening 704 is for the heat tracing pipe 5 to pass through, and the temperature sensor 705 is connected to the second temperature control switch 703 through the temperature sensing wire 702. The temperature sensor 705 is used to detect the temperature of the heat tracing pipe 5.

[0031] The specific structures of the downpipe blockage alarm device 8, the overflow pipe blockage alarm device 9, and the water seal level alarm device 10 are described in CN118912397A and will not be repeated in this embodiment.

[0032] The alarm system includes a controller 11, a transmitter 12, and several client terminals 13. A power supply system 15 supplies power to the controller 11 and the transmitter 12. The controller 11 has a first signal interface (specifically connected via wire 605) connected to the overflow pipe temperature alarm device 6, a second signal interface connected to the heat tracing pipe temperature alarm device 7, a third signal interface connected to the drain pipe blockage alarm device 8, a fourth signal interface connected to the overflow pipe blockage alarm device 9, and a fifth signal interface connected to the water seal level alarm device 10. The first, second, third, fourth, and fifth signal interfaces are connected in parallel.

The controller 11 has a maintenance switch 14, which is signal-connected to the controller 11.

[0033] The working process of the multi-channel real-time monitoring and alarm device for gas drainers of this utility model is as follows:

[0034] Overflow pipe temperature alarm device 6, heat tracing pipe temperature alarm device 7, downpipe blockage alarm device 8, overflow pipe blockage alarm device 9, and water seal level alarm device 10 respectively send the detected overflow pipe inlet temperature value, heat tracing pipe temperature value, downpipe level value, overflow pipe level value, and water seal level value inside the drain body to the first signal interface, second signal interface, third signal interface, fourth signal interface, and fifth signal interface of the controller 11. After signal conversion by the controller 11, the converted signals are transmitted to the transmitter. The transmitter sends the signals to the mobile APP. The mobile APP has 5 information channels that can display the overflow pipe inlet temperature information, heat tracing pipe temperature information, downpipe level information, overflow pipe level information, and water seal level information inside the drain body. If the temperature value or level value is within the normal range, "normal" will be displayed in the corresponding information channel. If the temperature or liquid level value is abnormal, "abnormal" will be displayed in the corresponding information channel. When an abnormal situation occurs, the controller 11 will remotely dial an alarm to the mobile APP, such as directly calling the staff to remind them to pay attention in time.

[0035] Meanwhile, the mobile app also has functions for dispatching maintenance orders and signing off on completed maintenance orders, forming a closed loop.

[0036] When the temperature or liquid level value is abnormal and maintenance is required for the gas drainer, the maintenance switch 14 is turned on. When the controller 11 detects that the maintenance switch 14 is turned on, the controller 11 stops sending alarm signals to the transmitter 12 and simultaneously sends maintenance signals to the transmitter 12. The transmitter sends the maintenance signals to the client 13. At this time, "Maintaining maintenance" is displayed on the mobile APP of the manager and maintenance personnel. After the maintenance is completed, the maintenance switch 14 is turned off, the controller 11 stops sending maintenance signals to the transmitter 12, and resumes the transmission of temperature and liquid level signals, restoring the alarm function.

[0037] Additionally, an alarm data statistics function can be added to count the number of faults at each point within a time period, providing data support for fault analysis.
