Abstract

The invention provides a single-tube-bundle split solid heat accumulation heat exchanger for making use of waste heat produced in the cement producing process. The heat exchanger comprises a low-temperature working medium tube bundle, a high-temperature smoke inlet, a high-temperature smoke outlet, a low-temperature working medium inlet, a low-temperature working medium outlet and a shell, wherein the inside of the heat exchanger shell is provided with a plurality of heat accumulation materials which are solid, the heat accumulation materials are stacked together, each heat accumulation material is provided with a first hole and a second hole, the first hole and the second hole of each heat accumulation materials are crossed but not communicated, the low-temperature working medium tube bundle penetrates through the second hole of each heat accumulation material, the outer diameter of the low-temperature working medium tube bundle is equal to the diameter of the second hole of each heat accumulation material, and the first holes of the heat accumulation materials form a through channel. According to the heat exchanger, waste heat produced in the content production process is made full use of, maximization of heat exchange efficiency is achieved, and the aims of protecting environment and saving energy are achieved.

Description

technical field [0001] The invention relates to a regenerative heat exchanger for utilizing waste heat in a high-efficiency cement production process, and belongs to the field of heat exchangers of F28d. [0002] Background technique [0003] With the rapid development of my country's economy, energy consumption is increasing day by day, and the problem of deteriorating urban air quality is becoming more and more prominent. It is urgent to save energy and reduce the emission of harmful environmental substances. In the common thermal power field, one of the main reasons for high energy consumption and serious pollution is that the exhaust gas temperature of the flue gas is too high, which wastes a lot of energy and causes environmental pollution. The cement industry is a high energy consumption and high pollution industry. The waste heat power generation system in the cement industry can recover and reuse the waste heat of exhaust gas to achieve the purpose of energy saving...
