Problems solved by technology

[0002] In the process control steps of the coal chemical industry and other industries, the temperature control of various reactors, converters and synthesizers requires the participation of thermocouples. The temperature measuring points on the thermocouples can measure the temperature of the gas flow in the converter synthesis tower. Most of the thermocouples are only equipped with a single temperature measuring core. The single temperature measuring core has low measurement accuracy and low reliability. The temperature measuring core with a double structure can effectively avoid the above shortcomings. How to ensure the temperature of the two cores Consistent orientation of the temperature measurement points is a key technical issue. The direction of the temperature measurement points toward the airflow in the synthesis tower can further improve the measurement accuracy. A methanol converter synthesis multi-point thermoelectric system can solve the above problems and effectively improve the measurement accuracy. Occasionally subject to further research and development

Abstract

The invention discloses a methanol converter synthetic multipoint thermocouple comprising a first armored core body, a second armored core body, and temperature measuring points. The first armored core body and the second armored core body are both provided with a plurality of temperature measuring points. The number of the temperature measuring points on the first armored core body and the number of the temperature measuring points on the second armored core body are the same and the measuring points on the first armored core body and the temperature measuring points on the second armored core body are disposed correspondingly one to one. The methanol converter synthetic multipoint thermocouple has beneficial effects that the first armored core body and the second armored core body are disposed, that the measuring points on the first armored core body and the temperature measuring points on the second armored core body are disposed correspondingly one to one, namely each same position is provided with two temperature measuring points so that the methanol converter synthetic multipoint thermocouple is improved in measurement accuracy and operation reliability, and that temperature measurement operation is not affected once a temperature measurement point generates a fault.
