Description

Technical Field

[0001] This utility model relates to a temperature measurement and protection device, and in particular to a temperature measurement and protection device for enamel towers. Background Technology

[0002] In existing technologies, the operating temperature of oxalic acid reaction towers is around 104°-108°C, and the working pressure is about 30 kPa. At this temperature, the oxalic acid solution is extremely corrosive. To avoid corrosion, the temperature measuring sleeve of traditional enamel-lined towers is made of carbon steel with an enamel lining. The top of the temperature measuring sleeve is bolted with tantalum material to directly contact the material to ensure timely temperature monitoring. This temperature sleeve is located above the bottom of the enamel-lined tower. Due to severe material erosion, the tantalum bolts are prone to loosening and the inner enamel wall may peel off. When leakage and corrosion occur, the temperature measurement of the platinum resistance thermometer will be inaccurate, triggering a chain reaction that can easily cause safety and environmental accidents and equipment shutdowns. Utility Model Content

[0003] In view of this, the main objective of this utility model is to provide a temperature measurement and protection device for enamel towers. Through this technical solution, the temperature measuring instrument is protected by a double-layered sleeve and an outer sleeve. The actual temperature of the corrosive medium is transmitted to the temperature measuring instrument in the intermediate sleeve via a corrosion-resistant temperature-conducting nail. The screwing table cooperates with the cover on the intermediate sleeve, and under the action of the conical guide plate, the temperature measuring head of the instrument is guided to always point towards the corrosion-resistant temperature-conducting nail and is fixed in contact, thereby effectively ensuring the timeliness and accuracy of temperature measurement. At the same time, it effectively improves the safety of temperature measurement protection. Even after the outer sleeve is eroded and corroded, the intermediate sleeve still functions, effectively extending the service life of the measurement and protection device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A temperature measurement and protection device for an enamel tower includes a measuring pipe, which is installed above the bottom of the enamel tower.

[0012] As a further technical solution, a stiffening plate is also included. The stiffening plate is fixed on the intermediate sleeve flange, and the intermediate sleeve and temperature measuring instrument can be easily hoisted and disassembled through the stiffening plate.
