Description

Technical Field

[0001] The utility model belongs to the technical field of drainers, and in particular relates to a real-time monitoring and alarm device for a gas drainer. Background Art

[0002] Gas drainers are mainly used to collect and drain condensate and dirt from gas pipes to ensure smooth flow of gas pipes. However, the following abnormalities are prone to occur during normal use of the drainer:

[0003] 1. The liquid level inside the drainer body drops, causing the liquid seal height of the drainer to become smaller. When the liquid level drops seriously, the gas cannot be sealed, and a gas leakage accident will occur. If there are people passing or staying nearby, it is easy to cause gas poisoning or fire and explosion accidents.

[0004] The current inspection method is: each drainer is equipped with a liquid level detection device, and during the inspection process, the on-duty personnel check the position of the liquid level detection device to determine whether the internal liquid level is normal.

[0005] 2. Increased foreign matter carried in the gas, coupled with inadequate cleaning of the drainer bottom, can lead to blockage of the secondary valve at the bottom of the downpipe, preventing the liquid in the gas pipeline from draining through the drainer. Severe downpipe blockage can prevent the liquid from draining out of the gas pipeline, causing it to accumulate inside. This can severely impact the normal flow of gas and significantly affect subsequent gas users.

[0006] 3. The overflow pipe of the drainer is blocked, causing condensed water to leak at the overflow port or the float connecting rod. The condensed liquid cannot enter the water seal pool, which can easily cause pollution to the surrounding environment and lead to environmental accidents.

[0007] The above three issues have a significant impact on production safety and environmental protection. To prevent these issues, we are currently implementing the following preventative measures: On-site personnel regularly inspect each drainer to check for changes in the drainer's float warning line, check for accumulated water flowing out of the downpipe sampling valve, and verify normal water flow at the overflow outlet.

[0008] Existing preventive measures cannot achieve real-time inspection and cannot guarantee the safe and stable operation of the drainer. In order to ensure the normal operation of the drainer and prevent the occurrence of abnormal problems, it is necessary to increase the frequency of inspections at the post. Due to the limited personnel of each unit, it is difficult to increase the frequency of inspections. In addition, if abnormal situations occur during the inspection intervals, if they cannot be discovered and measures taken in time, they can only be discovered during the next inspection by the post personnel. There are relatively large safety hazards on the drainer site.

[0009] Chinese patent document CN217234856U (202122984029.6) discloses an intelligent control and detection type anti-leakage gas drainer. When the gas drainer fails to drain properly, it can promptly alarm and avoid major safety accidents. However, this anti-leakage gas drainer cannot detect the specific location of the blockage, and personnel still need to conduct on-site inspections, resulting in long inspection and maintenance time, affecting production efficiency. Utility Model Content

[0010] The main purpose of the utility model is to provide a real-time monitoring and alarm device and method for a gas drainer. In order to solve the above problems of the gas drainer, the utility model mainly adds detection equipment and facilities to the drainer body, downpipe and overflow pipe, and monitors the liquid level changes at various locations on site in real time to achieve full-process detection of the drainer's working status. It can also identify the specific blockage position or liquid level sealing condition of the drainer, realize real-time monitoring of the drainer's operating status and rapid notification of abnormalities, thereby improving the safety of the drainer.

[0011] The utility model finds that no matter it is a coke oven gas, blast furnace gas or converter gas drainer, the condensate collected and generated contains a certain amount of chemical components or other granular impurities, especially the coke oven gas drainer, the condensate contains a large amount of tar, naphthalene or benzene, phenol and other chemicals, which are easy to adhere to the pipeline or the bottom of the drainer during the discharge process, especially in the low temperature season in winter, it is easy to cause blockage of the bottom of the drainer, downpipe and overflow pipe, that is, the main reason for the blockage is the drop in liquid temperature, and the tar, naphthalene or benzene, phenol and other chemicals in the condensate cannot be dissolved in the liquid, and cannot be discharged from the pipeline or container in time.

[0012] The current primary measure involves regular on-site inspections of drains by personnel, ensuring prompt resolution of any anomalies. However, because gas drains are located along the gas pipeline, they are often far from each other and from the duty station. This makes on-site inspections time-consuming and labor-intensive, and delayed inspections can easily lead to major production safety accidents. Therefore, timely detection of blockages is crucial for production safety. Furthermore, automated unblocking is crucial for reducing inspection and maintenance workloads.

[0013] The technical problem to be solved by the utility model is achieved by adopting the following technical solution: a real-time monitoring alarm device for a gas drainer, comprising a gas pipeline, a drainer body, a downpipe, an overflow pipe, a downpipe blockage alarm device, an overflow pipe blockage alarm device, a water seal liquid level alarm device and an alarm system;

[0014] The upper end of the drainer body is provided with an air inlet and an overflow port;

[0015] The downpipe is arranged between the gas pipeline and the drain body, and the lower end of the downpipe is inserted into the drain body from the air inlet. The gas pipeline and the drain body are both provided with a heating device;

[0016] The overflow pipe is connected to the overflow port, the overflow port is located above the lower end surface of the downpipe, and the lower end surface of the downpipe is located below the liquid level of the drainer body;

[0017] The downpipe blockage alarm device includes a first connecting pipe and a first liquid level measuring device provided in the vertical section of the downpipe, wherein the upper and lower ends of the first connecting pipe are respectively connected to the downpipe, and the first liquid level measuring device is used to measure the liquid level height in the first connecting pipe;

[0018] The overflow pipe blockage alarm device includes a second connecting pipe and a second liquid level measuring device provided in the vertical section of the overflow pipe, wherein the upper and lower ends of the second connecting pipe are respectively connected to the overflow pipe, and the second liquid level measuring device is used to measure the liquid level height in the second connecting pipe;

[0019] The water seal liquid level alarm device includes a third liquid level measuring device, which is used to measure the liquid level height in the drainer body;

[0020] The alarm system is electrically connected to the first liquid level measuring device, the second liquid level measuring device and the third liquid level measuring device respectively. When the liquid level heights measured by the first liquid level measuring device, the second liquid level measuring device and the third liquid level measuring device exceed the corresponding threshold requirements, the alarm system issues a fault alarm at the corresponding position.

[0021] Preferably, in the present invention, when the liquid level measured by the first liquid level measuring device exceeds the threshold requirement, the alarm system sends a first alarm signal;

[0022] When the liquid level measured by the second liquid level measuring device exceeds the threshold requirement, the alarm system sends a second alarm signal;

[0023] When the liquid level measured by the third liquid level measuring device exceeds a threshold, the alarm system issues a third alarm signal. By utilizing the alarm system, different alarm signals are sent for faults at different locations within the drain, enabling rapid identification of specific drain faults and facilitating the implementation of specific countermeasures.

[0024] Preferably, the third liquid level measuring device of the present invention includes a float, a float connecting rod and a travel switch;

[0025] The float is arranged in the drain body, the float connecting rod is arranged vertically and can be moved up and down on the drain body, and the lower end of the float connecting rod is connected to the float;

[0026] The travel switch is mounted on the float rod. When the travel switch contacts the top of the drain body, the alarm system is triggered. Using the travel switch to monitor whether the liquid level exceeds the threshold, this solves the problem of a float level gauge being unable to automatically monitor the liquid level.

[0027] The present invention preferably further includes a water seal container, the overflow pipe being connected to the water seal container, with the lower end opening of the overflow pipe being located below the liquid level of the water seal container. The water seal container is provided to collect condensed water flowing out of the overflow port and simultaneously seal the overflow pipe, thereby preventing the liquid level of the drain body from dropping and the lower end of the downpipe from rising above the liquid level, thereby preventing gas from leaking out of the overflow port.

[0028] Preferably, the present invention further includes a first temperature sensor and a first heating module;

[0029] The first temperature sensor and the first heating module are both installed in the downpipe. By installing the first temperature sensor and the first heating module, the temperature in the downpipe is monitored by the first temperature sensor. When the temperature in the downpipe is too low, which may cause impurities to precipitate, the first heating module is used to heat the downpipe. Alternatively, when the downpipe is blocked, the liquid in the downpipe is heated to dissolve impurities in the blockage, thereby clearing the downpipe. This can reduce maintenance workload and achieve automatic drainage.

[0030] Preferably, the present invention further includes a second temperature sensor and a second heating module;

[0031] The second temperature sensor and the second heating module are both disposed within the overflow pipe. By disposing the second temperature sensor and the second heating module, the temperature within the overflow pipe is monitored by the second temperature sensor. When the temperature within the overflow pipe is too low, which may cause impurities to precipitate, the second heating module is used to heat the interior of the overflow pipe. Alternatively, when the overflow pipe is clogged, the liquid within the overflow pipe is heated to dissolve impurities in the clogged area, thereby unclogging the overflow pipe, reducing maintenance workload and achieving automatic unclogging.

[0032] Preferably, the alarm system of the present invention includes a transmitter;

[0033] The transmitter is used to transmit alarm signals corresponding to the first, second, and third liquid level measuring devices, as well as the location or model information of the gas drainer, to the monitoring terminal. When an abnormality occurs, the transmitter can immediately send a message to the duty station, alerting personnel to immediately investigate and resolve the potential accident.

[0034] In the present invention, the first connecting pipe is preferably located between the first and second valves of the downpipe, and the second connecting pipe is located in the middle section of the overflow pipe. Since the downpipe is equipped with a heat tracing device, the first valve is closer to the gas pipeline and less susceptible to clogging, while the second valve is at a lower temperature and more susceptible to clogging. Therefore, the first connecting pipe is located between the first and second valves of the downpipe. Since the overflow pipe is farther from the drain body, the temperature at the lower end is also lower, and clogging is more likely to occur at the lower end of the overflow pipe. Therefore, the second connecting pipe is located in the middle section of the overflow pipe.

[0035] The utility model preferably further comprises a gas leakage monitoring device, and a gas leakage monitoring device is provided on the outside of each drainer body;

[0036] The gas leak monitoring device is electrically connected to the alarm system. When the gas leak monitoring device detects a gas leak, the alarm system issues a fault alarm for the corresponding location. By installing a gas leak monitoring device on each drain body, it can monitor for gas leaks, allowing for timely detection and alarm, thus preventing safety accidents.

[0037] In the present invention, when the gas leakage monitoring device detects a gas leak, the alarm system sends a fourth alarm signal. Using a separate alarm signal to identify the gas leak facilitates taking targeted countermeasures.

[0038] Compared with the prior art, the beneficial effect of the present invention is that since both the gas pipeline and the drainer body are provided with heating devices, blockage at the upper end of the downpipe and the upper end of the overflow pipe can be avoided.

[0039] The utility model sets a first connecting pipe in the vertical section of the downpipe, and uses a first liquid level measuring device to measure the liquid level height in the first connecting pipe. Since the upper and lower ends of the first connecting pipe are respectively connected to the downpipe, when the downpipe is not blocked, no water will be stored in the first connecting pipe; when the bottom of the downpipe is blocked, the accumulated water in the downpipe will enter the first connecting pipe, which will be detected by the first liquid level measuring device, and the alarm system will issue a warning of blockage at the corresponding position.

[0040] The utility model sets a second connecting pipe in the vertical section of the overflow pipe, and uses a second liquid level measuring device to measure the liquid level height in the second connecting pipe. Since the upper and lower ends of the second connecting pipe are respectively connected to the overflow pipe, it is possible to monitor in real time whether the lower end of the overflow pipe is blocked, and the alarm system issues a warning of blockage at the corresponding position.

[0041] The utility model also utilizes a third liquid level measuring device to monitor the liquid level in the drain body. When the liquid level in the drain body is too low and the bottom of the downpipe cannot be sealed, the alarm system issues a warning of a sealing problem at the corresponding position.

[0042] The utility model has a simple structure. By adding a real-time monitoring alarm device at the part of the drainer where problems are likely to occur, it replaces the work of regular on-site inspections by on-duty personnel, ensures that the gas facilities are under real-time safety control, and prevents the occurrence of production safety accidents during the use of the gas facilities.

[0043] The utility model can be uniformly promoted and applied to all gas drainers managed by a same production plant, which can greatly reduce the number of operators and inspectors of gas equipment facilities, and lay a foundation for optimizing the human resources of the enterprise.

The downpipe 3 is vertically disposed and is spaced apart from each other by a first valve and a second valve (not shown). The lower end of the downpipe 3 is inserted into the drain body 2 through the air inlet 201. Both the gas pipe 1 and the drain body 2 are equipped with a heat tracing device. This heats the gas pipe 1 and the drain body 2 to prevent impurities from condensing inside the gas pipe 1 and the drain body 2 and adhering to the inner walls, preventing them from being discharged.

[0057] The overflow pipe 4 is sealedly connected to the overflow port 202, and the overflow port 202 is located above the lower end surface of the downpipe 3, and the lower end surface of the downpipe 3 is located below the liquid level of the drainer body 2, so as to achieve sealing of the gas in the gas pipeline 1 and prevent gas leakage.

[0058] like Figure 1 As shown, the downpipe blockage alarm device 5 includes a first connecting pipe 51 and a first liquid level measuring device 52 arranged in the vertical section of the downpipe 3. The upper and lower ends of the first connecting pipe 51 are respectively connected to the downpipe 3. The first liquid level measuring device 52 is used to measure the liquid level height in the first connecting pipe 51.

[0059] like Figure 1 and Figure 3 As shown, the overflow pipe blockage alarm device 6 includes a second connecting pipe 61 and a second liquid level measuring device 62 arranged in the vertical section of the overflow pipe 4. The upper and lower ends of the second connecting pipe 61 are respectively connected to the overflow pipe 4. The second liquid level measuring device 62 is used to measure the liquid level height in the second connecting pipe 61.

[0060] Specifically, the first connecting pipe 51 is arranged between the first valve and the second valve of the downpipe 3 , and the second connecting pipe 61 is arranged in the middle section of the overflow pipe 4 .

[0061] like Figure 1 As shown, the water seal liquid level alarm device 7 includes a third liquid level measuring device 71, which is used to measure the liquid level height in the drainer body 2. The first liquid level measuring device 52, the second liquid level measuring device 62 and the third liquid level measuring device 71 are all electronic liquid level gauges.

[0062] The alarm system is electrically connected to the first liquid level measuring device 52, the second liquid level measuring device 62 and the third liquid level measuring device 71 respectively. When the liquid level heights measured by the first liquid level measuring device 52, the second liquid level measuring device 62 and the third liquid level measuring device 71 exceed the corresponding threshold requirements, the alarm system issues a fault alarm at the corresponding position.

[0063] When the liquid level measured by the first liquid level measuring device 52 exceeds a threshold requirement, the alarm system issues a first alarm signal.

[0064] When the liquid level measured by the second liquid level measuring device 62 exceeds a threshold requirement, the alarm system issues a second alarm signal.

[0065] When the liquid level measured by the third liquid level measuring device 71 exceeds a threshold requirement, the alarm system issues a third alarm signal.

[0066] Specifically, the alarm system includes a transmitter, which is electrically connected to the first liquid level measuring device 52 , the second liquid level measuring device 62 , and the third liquid level measuring device 71 .

[0067] The transmitter is used to send the alarm signals corresponding to the first liquid level measuring device 52, the second liquid level measuring device 62 and the third liquid level measuring device 71 and the location information or model information of the gas drainer to the monitoring terminal, which includes a mobile phone or a computer.

[0068] like Figure 1 and Figure 2 As shown, the third liquid level measuring device 71 includes a float 711 , a float connecting rod 712 and a travel switch 713 .

[0069] The float 71 is disposed in the drainer body 2 , and the float connecting rod 712 is vertically disposed and movable up and down on the drainer body 2 . The lower end of the float connecting rod 712 is connected to the float 711 .

[0070] The travel switch 713 is provided on the float connecting rod 712, and the alarm system is triggered when the travel switch 713 contacts the top of the drain body 2. Specifically, the travel switch 713 is electrically connected to the transmitter, and when the travel switch 713 is closed, the transmitter sends a signal.

[0071] The gas drainer real-time monitoring and alarm device further includes a water seal container 8, to which the overflow pipe 4 is connected, and the lower end opening of the overflow pipe 4 is located below the liquid level of the water seal container 8. The water seal container 8 is specifically a water seal tank, located below the overflow port 202.

[0072] The gas drainer real-time monitoring and alarm device further comprises a first temperature sensor and a first heating module.

[0073] The first temperature sensor and the first heating module are both arranged in the downpipe 3 .

[0074] The gas drainer real-time monitoring and alarm device further comprises a second temperature sensor and a second heating module.

[0075] The second temperature sensor and the second heating module are both arranged in the overflow pipe 4 .

[0076] The gas drainer real-time monitoring and alarm device also includes a gas leakage monitoring device. A gas leakage monitoring device (not shown in the figure) is provided on the outside of each drainer body 2, and the gas leakage monitoring device is fixedly arranged on the drainer body 2.

[0077] The gas leakage monitoring device is electrically connected to the alarm system. When the gas leakage monitoring device detects gas leakage, the alarm system issues a fault alarm at the corresponding location.

[0078] When the gas leakage monitoring device detects gas leakage, the alarm system sends a fourth alarm signal.

[0079] The method for real-time monitoring of a gas drainer using the above-mentioned real-time monitoring and alarm device for a gas drainer comprises the following steps:

[0080] The first liquid level measuring device 52 is used to measure the liquid level in the first connecting pipe 51 .

[0081] The second liquid level measuring device 62 is used to measure the liquid level in the second connecting pipe 61 .

[0082] The third liquid level measuring device 71 is used to measure the liquid level in the drainer body 2 .

[0083] The gas leakage monitoring device is used to monitor whether there is gas leakage in the drainer body 2.

[0084] When the liquid levels measured by the first liquid level measuring device 52 , the second liquid level measuring device 62 and the third liquid level measuring device 71 exceed corresponding threshold requirements or the gas leakage monitoring device detects gas leakage, the alarm system issues a fault alarm at the corresponding position.

[0085] A first temperature sensor and a first heating module are provided at the downpipe 3 or the first connecting pipe 51 .

[0086] A second temperature sensor and a second heating module are provided at the overflow pipe 4 or the second connecting pipe 61 .

[0087] When the temperature measured by the first temperature sensor is lower than the preset temperature, the first heating module is controlled to heat the liquid in the downpipe 3 or the first connecting pipe 51 .

[0088] When the temperature measured by the second temperature sensor is lower than the preset temperature, the second heating module is controlled to heat the liquid in the overflow pipe 4 or the second connecting pipe 61 .

[0089] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention designs and transforms three aspects of gas drainers that are prone to problems.

[0090] The first part of the design and modification is the liquid level display device (float connecting rod). The limit switch mounting bracket is fixed to the float connecting rod 712 through the connecting rod fixer on the upper part of the float connecting rod. The limit switch 713 is installed at the lower part of the limit switch mounting bracket. When the liquid level inside the drainer body 2 drops, the limit switch 713 drops along with the float connecting rod 712 and contacts the top steel structure of the drainer body 2, triggering the limit switch 713. The trigger signal of the limit switch 713 is transmitted to the transmitter through the wire. The transmitter calls the mobile phone number entered in advance and sends a message to the mobile phone through WeChat to issue an alarm prompt and locate the drainer position number.

[0091] The second area to be redesigned was the drainpipe. Between the first and second valves of downpipe 3, the downpipe was modified by adding a set of connecting pipes with a diameter of DN50 or greater. This connected the bottom and top of the connecting pipes to the downpipes, respectively. This ensures that if the downpipe becomes clogged and condensate cannot be drained, liquid will accumulate in the connecting pipes. When the liquid level in the connecting pipe reaches a certain height, the liquid level measuring device is triggered, which transmits a signal to the transmitter via a wire. The transmitter calls the pre-entered mobile phone number and sends a message to the mobile phone via WeChat, providing an alarm and locating the drainpipe's position number. Because the drainpipe draining steam is directly connected to the gas pipeline, the tightness of the installation position of the liquid level detection device must be ensured, and it must meet certain pressure resistance and corrosion resistance requirements.

[0092] The third area of ​​the design modification was the drainer's overflow pipe. A connecting pipe with a diameter of DN50 or larger was added 20-30 cm below the overflow pipe's inlet. This connects the bottom and top of the connecting pipe to the overflow pipe, respectively. This prevents condensate from entering the water seal tank if the overflow pipe becomes clogged, causing it to accumulate inside the connecting pipe. When the liquid level in the connecting pipe reaches a certain level, it triggers a level measurement device, which transmits a signal via wires to a transmitter. The transmitter then calls a pre-entered mobile phone number and sends a message to the same phone via WeChat, providing an alarm and locating the drainer's location.

[0093] The working process of this utility model:

[0094] In this embodiment, during the use of the gas drainer, when abnormal leakage occurs in the drainer body 2 and the bottom inspection port, or the winter heating equipment causes the evaporation of the liquid in the drainer to increase, and the liquid level inside the drainer body 2 decreases, the float connecting rod decreases with the liquid level, and the limit switch on the device falls, hitting the top steel plate of the drainer body 2, triggering the limit switch, and transmitting the alarm signal to the transmitter through the signal line. The transmitter calls the set mobile phone and sends a WeChat notification to remind the on-site personnel to investigate and handle the problem.

[0095] When the downpipe of the gas pipeline or the overflow pipe of the drainer is blocked and the liquid cannot be discharged, the liquid accumulates inside the pipeline, the liquid level rises, and the liquid enters the connecting pipe. As the liquid level rises, the liquid level detection device is triggered. The liquid level measuring device transmits the alarm signal to the transmitter through the wire. The transmitter calls the mobile phone number entered in advance and sends a WeChat notification to remind the on-duty personnel to go to the site for investigation and processing.

[0096] The alarm information of the three parts of each drainer can be connected to a transmitter. No matter which part has an abnormal situation, the relevant alarm information will be sent to the set collection, which can reduce the equipment investment cost.

[0097] The effect of the utility model is to reduce the inspection frequency, monitor the working condition of the drainer by changing the liquid level, prevent the blockage of the drainer from being discovered in time and affecting the pipeline gas transportation, prevent the gas leakage caused by too low water level and the gas breakdown from being discovered in time and causing poisoning accidents, and prevent the overflow pipe from being blocked and causing environmental accidents caused by condensate overflow. Through real-time monitoring of the drainer, the damage caused by the above problems can be avoided from being further expanded, and the fault location can be discovered in time.
