Heat accumulating type heat exchanger for waste-heat utilization during cement production process

Abstract

The invention provides a heat accumulating type heat exchanger for waste-heat utilization during a cement production process. The heat exchanger comprises a first pipe bundle, a second pipe bundle, a high temperature flue gas inlet, a high temperature flue gas outlet, a low temperature working medium inlet, a low temperature working medium outlet and a housing, wherein the first pipe bundle and the second pipe bundle are arranged in the housing; the first pipe bundle is used for communicating flue gas generated during the cement production process; the second pipe bundle is used for being communicated with the low temperature medium; the first pipe bundle and the second pipe bundle are arranged in cross-connection; the flue gas enters from the high-temperature flue gas inlet, passes the first pipe bundle, and is discharged from the high temperature flue gas outlet; the low temperature medium enters from the low temperature medium inlet, passes the second pipe bundle, and is discharged from the low temperature medium; heat accumulating materials are placed in the space out of the first pipe bundle and the second pipe bundle. The heat accumulating type heat exchanger fully utilizes the waste heat during the cement production, and enables the heat exchange efficiency to the maximum, so as to save energy and achieve the goal of environmental protection and energy conservation.

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. Background technique [0002] 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 and emiss...
