Online test system of high temperature calcined coke heat exchanger

Abstract

An online test system of a high temperature calcined coke heat exchanger belongs to the technical field of waste heat utilization of solid high temperature materials and is characterized in that a high temperature calcined coke waste heat utilizing water-steam circulation system is connected with a water-steam parameter test system and a material temperature test system. The water-steam parameter test system comprises a first heat resistor (8), a second heat resistor (42), an ultrasonic flowmeter (18), a two-phase-flow flowmeter (29) and a sight glass (34), the first heat resistor (8) and ultrasonic sensors (11) are arranged on an outer heat exchange water inlet pipe (9) between a third adjusting valve (16) and an outer heat exchanger (4), the first heat resistor (8) and an ultrasonic sensor (11) are arranged on an inner heat exchanger water inlet pipe (10) between a fourth adjusting valve (17) and an inner heat exchanger (7), and the two ultrasonic sensors (11) are connected with the ultrasonic flowmeter (18) through signal wires (27). The online test system is capable of conducting comprehensive performance tests on high temperature calcined coke special heat exchangers on a pot type calcining furnace.

Description

technical field [0001] The high-temperature calcined coke heat exchanger online test system belongs to the technical field of waste heat utilization of solid high-temperature materials, and specifically relates to an on-line test system for a high-temperature calcined coke heat exchanger of a tank type calciner. Background technique [0002] Petroleum coke is calcined at high temperature (about 1350°C) to remove its volatile matter, and its graphitization degree is improved, thereby improving density, mechanical strength, heat resistance and chemical stability, and improving electrical conductivity. Calcined coke is mainly used in the production of aluminum electrolytic anodes, graphite electrodes for steelmaking, recarburizers, smelting industrial silicon, carbon paste products, emery and other carbon products, and is an important basic raw material. The temperature of the calcined coke discharged from the pot calciner is as high as 1000°C, and the remaining heat has high u...
