Activated carbon desulfurization system and temperature detection device thereof

一种活性炭脱硫系统及其温度检测装置

Abstract

本发明公开了一种温度检测装置,包括保护套管及设于所述保护套管中的热电偶,还包括导热环,多个所述导热环在所述保护套管内部沿轴向间隔设置于各检测点位,并且与所述保护套管内壁相接触;各所述热电偶的测温端部固定在与之相应的所述导热环上部,并位于同一水平面上。该温度检测装置可以检测同一水平面上的活性炭温度,能够快速测量到吸附塔内的温度,而且,更接近真实的活性炭温度,保证了温度检测的可靠性、准确性、实时性,避免了现有温度检测装置存在的滞后、响应慢、误差大等问题。本发明还公开了设有所述温度检测装置的活性炭脱硫系统。
The invention discloses a temperature detection device. The device comprises a protection casing pipe, thermocouples arranged in the protection casing pipe and thermal conduction rings. The plurality of thermal conduction rings are arranged at detection point sites with intervals along an axial direction in the protection casing pipe and are contacted with an inner wall of the protection casing pipe. A temperature measurement end portion of each thermocouple is fixed to an upper portion of the corresponding thermal conduction ring and the two are located in a same horizontal plane. The temperature detection device can detect an activated carbon temperature on the same horizontal plane and can rapidly measure a temperature in an adsorption tower. The temperature is close to the actual activated carbon temperature. Reliability, accuracy and real-time performance of temperature detection are guaranteed and problems that an existing temperature detection device is lag; a response is slow; an error is large and so on are avoided. The invention also discloses an activated carbon desulfurization system provided with the temperature detection device.
