Anti-leakage adjustable multi-point thermocouple for reactor catalyst measuring point nozzle

Abstract

The invention discloses a leakage-resistant adjustable multi-point thermocouple for a reactor catalyst measuring point nozzle in the field of leakage-resistant thermocouples. The leakage-resistant adjustable multi-point thermocouple for the reactor catalyst measuring point nozzle comprises a junction box. By arranging a multi-point temperature measuring mechanism and a rotating mechanism, a third temperature transfer rod moves downwards and is close to a reaction center, when a temperature transfer plate is separated from a second temperature transfer rod and enters the reactor, the temperature transfer plate is in contact with air in the reactor, and the temperature is quickly transferred into the third temperature transfer rod, at the moment, the temperature of the second temperature transfer rod is gradually increased; meanwhile, trapezoidal clamping blocks are separated from the clamping grooves, and air springs are opened in a limiting manner, so a temperature transfer plate is expanded outwards, the temperature transfer range is expanded, the temperature transfer plate rotates while moving downwards under the action of the rotating mechanism, air in the reactor is mixed, flowing of the air is accelerated, and the temperature around the temperature transfer plate is kept uniform; therefore, measurement accuracy is improved, and the catalyst of the reaction gas can fully react.

Description

technical field [0001] The invention discloses a leak-proof and adjustable multi-point thermocouple used for a reactor catalyst measuring point nozzle in the field of leak-proof thermocouples. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument. The shapes of various thermocouples are often very different due to needs, but their basic structures are roughly the same, usually composed of main parts such as thermal electrodes, insulating sleeve protection tubes, and junction boxes, and are usually associated with display instruments, recording instruments, and electronic regulators. used together with the device. [0003] In the prior art, in order to ensure that the catalyst in the measuremen...

Problems solved by technology

[0005] The purpose of the present invention is to provide a leak-proof adjustable multi-point thermocouple for the catalyst measuring point nozzle of a reactor, to solve the above-mentioned background technology. In the actual process, due to the diffusion and exchange of temperature, the closer to the reaction position, the temperature The more accurate it is, the temperature in the reactor needs to be measured at multiple points to ensure the authenticity of the measurement and avoid the problem of insufficient catalyst reaction due to measurement errors
