Abstract

The invention belongs to the field of measurement and calibration of heat content of high-temperature pyrolysis coal gases, and particularly relates to a device and a method for online measurement andcalibration of the heat content of a high-temperature pyrolysis coal gas. Part of the high-temperature coal gas passes through a quartz sand filter, a flue gas flow meter and heat exchange equipmentwhich is manufactured by arranging a temperature measuring element, a water system, a heat preservation system, a water side heat exchange element in parallel and the like, the heat exchange amount ofthe coal gas and the water is obtained according to a formula Q = Cm delta t, and the heat contained in all the coal gas is obtained according to the coal gas flow and heat data. According to the method, the heat of the high-temperature coal gas is accurately measured, clean and efficient gradient utilization of the heat is achieved, the heat utilization rate is maximized, and heat utilization equipment cannot be damaged due to the fact that the heat utilization equipment bears the limit temperature.

Description

technical field [0001] The invention belongs to the field of measuring and calibrating the heat content of high-temperature pyrolysis gas, and in particular relates to a device and method for on-line measuring and calibrating the heat content of high-temperature pyrolysis gas. Background technique [0002] In order to further improve the level of clean and efficient utilization of coal and effectively alleviate the state of my country's rich coal, poor oil and little gas, major domestic groups and scientific research institutes are using coal as raw material to produce oil, gas and other chemical products through pyrolysis and gasification processes. product. Due to different gasification and pyrolysis temperatures, the amount of components contained in the crude gas produced is different. The traditional calculation method is difficult to measure and calibrate the heat contained in the gas on-line, and the process is complicated; the temperature of the gas produced by the py...
