Description

Technical Field

[0001] This utility model relates to the field of joint shaft protection technology, and more specifically, to a boiler heat tracing condensate temperature monitoring device. Background Technology

[0002] Steam boiler heat tracing systems are a widely used equipment heat tracing technology in industries such as chemical, petroleum, and pharmaceutical. It uses steam as the heat medium to provide heat to process pipelines or equipment that require insulation. These devices often contain liquids, which, if kept at excessively low temperatures during operation or storage, may crystallize, solidify, or increase in viscosity, thus affecting the normal operation of the process. By using steam heat tracing, it is possible to ensure that pipelines or equipment are maintained at suitable operating temperatures.

[0003] In steam tracing systems, the steam contains a large amount of condensate. If this condensate is not drained in time, it will affect the normal operation of the steam and the heating effect of the medium. Therefore, a steam trap and a drain pipe need to be installed at the steam tracing outlet to remove the condensate.

[0004] Most existing boiler heat tracing temperature monitoring devices employ simple temperature detection structures, lacking safe and stable monitoring and early warning mechanisms. Their practicality and durability also need improvement. Meanwhile, invention patent CN114942397A discloses a novel heat tracing monitoring device, including a fixing unit comprising a threaded handle, a toothed plate post, a connector, and a heat tracing cable head. One end of the threaded handle extends into a receiving cavity, and the toothed plate post is disposed within the receiving cavity. The device includes a rotating connecting toothed plate column, a connector located within a receiving cavity, a heat tracing cable head extending into the receiving cavity and connected to the connector, and a clamping unit comprising a pressing column, a semi-open cavity located inside the clamping housing, a push block, and a clamping member. One end of the pressing column extends into the receiving cavity and is connected to the toothed plate column, while the other end is located within the semi-open cavity. The push block is located within the semi-open cavity, and the clamping member is located within the semi-open cavity and rotatably connected to the inner wall of the clamping housing. This device is not suitable for boiler heat tracing drain pipes and lacks a low-temperature early warning structure. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] This embodiment installs the device on the drain pipe of the boiler heat tracing system. The drain temperature is monitored by a temperature sensor connected to the inner wall of the drain pipe. When the water temperature is too low, an alarm is triggered to alert staff, allowing for timely intervention and preventing the low drain temperature from affecting the boiler heat tracing system's operating efficiency. The specific implementation method is as follows:

[0032] like Figures 1 to 4As shown in the figure, a monitoring device for the temperature of the boiler tracing steam condensate includes a monitoring box 1, a mounting base 2, and a temperature monitoring component. The monitoring box 1 is closely attached to the surface of the steam condensate pipeline of the boiler tracing system through the mounting base 2. A temperature monitoring component is provided on the monitoring box 1. The temperature monitoring component includes an alarm 6 and a temperature sensor 8. The alarm 6 is installed on the top of the monitoring box 1, and the temperature sensor 8 is arranged inside the monitoring box 1. The detection end of the temperature sensor 8 passes through the mounting base 2 and is connected to the inside of the steam condensate pipeline of the boiler tracing system. By installing the device on the steam condensate pipeline of the boiler tracing system, the temperature of the steam condensate can be monitored by connecting the temperature sensor 8 inside the monitoring box 1 to the inner wall of the steam condensate pipeline. When the water temperature is too low, an alarm can be issued through the alarm 6 for reminder, which is convenient for the staff to handle in time and avoid the influence of too low steam condensate temperature on the operation efficiency of the boiler tracing.

[0033] Too low steam condensate temperature means that the condensate water after saturation temperature condensation must continue to exchange heat in the heat exchanger to reduce the discharge temperature of the condensate water, which also means that there is water accumulation inside the steam equipment, resulting in a decrease in the heating efficiency of the heat exchanger. The condensate water occupies part of the heat exchange area but provides only a small amount of heat, which makes the heating efficiency of the equipment low and further affects the production efficiency. The too low temperature of the heat exchanger wall surface and temperature gradient are completely unacceptable for some processes such as product heating and sterilization in the pharmaceutical process. Obviously, the subcooled discharge temperature of the steam trap reduces the output rate of the equipment. To meet the process requirements, it is necessary to increase the opening of the steam supply valve, increase the steam pressure, and even open the bypass of the steam trap, ultimately resulting in an increase in steam consumption. The water accumulation will cause a temperature difference between the upper and lower parts of the heat exchange equipment, affecting the stability of product quality and the service life of the equipment, and is also prone to water hammer.

[0034] Generally, for steam heat exchangers, loads, and their stable applications that are for heat preservation, heat retention, and non-critical applications, energy can be saved by reducing the discharge temperature of the condensate water. The steam traps for reducing the discharge temperature of the condensate water include bimetallic steam traps, thermostatic diaphragm steam traps, throttle hole steam traps, and fixed temperature discharge steam traps based on the principle of liquid expansion.

[0035] A controller 14 is installed inside the monitoring box 1. The temperature sensor 8 is electrically connected to the alarm 6 through the controller 14. A temperature display 4 is provided on the front of the monitoring box 1, and the temperature display 4 is electrically connected to the temperature sensor 8. Under the action of the controller 14, the temperature display 4 and the temperature sensor 8 can be controlled, and it can also be connected to the boiler tracing system for linkage control. Under the action of the temperature display 4, the temperature data can be displayed, which is convenient for the staff to view.

[0036] A temperature detection channel 9 is formed at the center of the back of the monitoring box 1 and the middle position of the mounting base 2. The detection end of the temperature sensor 8 is inserted into the temperature detection channel 9. The detection end of the temperature sensor 8 is a temperature-sensing probe. The temperature detection channel 9 allows the detection end of the temperature sensor 8 to pass through easily. With the precise contact of the temperature-sensing probe after it is inserted into the pipe, the accuracy of temperature detection can be improved.

[0037] A sealing ring 10 is provided on the inner wall of the temperature detection channel 9, and the sealing ring 10 fits tightly against the detection end of the temperature sensor 8. The sealing ring 10 can limit and seal the outside of the detection end of the temperature sensor 8, improve the sealing performance at its connection with the pipeline, and prevent leakage.

[0038] The outer surface of the monitoring box 1 is provided with a reinforcing plate 12, and the inner wall of the monitoring box 1 is provided with an anti-interference plate 13. The anti-interference plate 13 is made of an anti-electromagnetic interference material. The reinforcing plate 12 on the outer surface of the monitoring box 1 can improve its strength and enhance its pressure resistance, making it less prone to damage. The anti-interference plate 13 inside the monitoring box 1 can prevent electromagnetic interference from affecting the normal use of the device, further improving the durability of the device. The inner wall of the monitoring box 1 is also provided with an insulating coating to prevent leakage and other problems.

[0039] The monitoring box 1 has a heat dissipation grid 5 on its side wall, and a dustproof net is installed on the inner side of the heat dissipation grid 5. The heat dissipation grid 5 can improve the heat dissipation effect of the monitoring box 1 and avoid overheating. The dustproof net can prevent dust from entering the monitoring box 1 and affecting the use of the internal components of the device.

[0040] The top of the monitoring box 1 is equipped with an alarm light 7, which is electrically connected to the temperature sensor 8. The alarm light 7 can illuminate in abnormal situations such as excessively low temperatures, thus making it easier to remind staff.

[0041] The mounting base 2 has a fixing plate on its side, and several fixing holes 3 are formed on the fixing plate. By using the mounting base 2 located on the back of the monitoring box 1, the device can be installed and fixed on the surface of the drainage pipe through the fixing plate and fixing holes 3. At the same time, the middle of the mounting base is provided with a channel to facilitate the passage of the temperature sensor probe, which facilitates the stable use of the device on the pipeline.

[0042] The mounting base 2 has an arc-shaped groove on the side that fits against the pipe, and the inner wall of the arc-shaped groove is provided with a heat insulation plate 11. The heat insulation plate 11 can prevent heat from the pipe from being transferred to the device and affecting the service life of the device.

[0043] Working Principle: The device is installed on the drain pipe of the boiler heat tracing system. The temperature of the drain water is monitored by a temperature sensor connected to the inner wall of the drain pipe inside the monitoring box. When the water temperature is too low, an alarm will sound to alert staff, allowing for timely intervention and preventing the drain water temperature from affecting the boiler heat tracing efficiency. The mounting base on the back of the monitoring box allows for secure installation on the drain pipe surface. A channel in the center of the mounting base facilitates the passage of the temperature sensor probe, ensuring stable operation of the device on the pipe. A reinforcing plate on the outer surface of the monitoring box enhances its strength and pressure resistance, making it less prone to damage. An anti-interference plate inside the monitoring box prevents electromagnetic interference from affecting the normal operation of the device, further improving its durability.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
