Abstract

A waste-heat utilization steam and water circulating system for high-temperature calcined-coke of multiple tank-type calcining furnaces; a set of steam collecting bags (1) is respectively disposed at an intermediate position between every two tank-type calcining furnaces (11) and on the outer side of the two outermost tank-type calcining furnaces (11); the steam collecting bags (1) are all disposed on a platform (13), all heat exchangers arranged below each tank-type calcining furnace (11) being divided into two groups from the middle of the furnace body of the tank-type calcining furnace (11); a falling main (2), an internal heat exchanger rising main (4), and an external heat exchanger rising main (3) are provided for each group of heat exchangers; the falling main (2) communicates with all external heat exchanger water inlet pipes (9) and all internal heat exchanger water inlet pipes (10) in the group; the internal heat exchanger rising main (4) communicates with all internal heat exchanger water outlet pipes (6) in the group; and the external heat exchanger rising main (3) communicates with all external heat exchanger water outlet pipes (5) in the group. The system can work with multiple tank-type calcining furnaces, requires less investment, and has a compact structure and small footprint.

Description

technical field [0001] The utility model relates to a steam-water circulation system for utilizing waste heat of high-temperature calcined cokes of multiple tank-type calciners, which belongs to the technical field of waste heat utilization of solid high-temperature materials, and specifically relates to a steam-water circulation system for utilizing waste heat of high-temperature calcined cokes of multiple tank-type calciners. Background technique [0002] Calcined coke is widely used in the production of aluminum electrolytic anodes, graphite electrodes for steelmaking, recarburizers, industrial silicon and other carbon products, and is an important basic raw material. The output of calcined coke in my country ranks first in the world. In 2010, the total output was 10.32 million tons, and more than 2 / 3 were produced by tank calciners. The pot calciner is composed of many calciner pots, which are arranged in two rows, and there is a calcined coke discharge port under each c...
