Abstract

The invention provides a heat accumulating type heat exchanger for pipeless waste heat utilization in a cement manufacturing process. The heat exchanger comprises a heat accumulating material, 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 casing, wherein the heat accumulating material is arranged in the casing; the heat accumulating material is a solid heat accumulating material; a plurality of communicated first holes and a plurality of second holes of heat accumulating material are formed in the heat accumulating material; the first holes and the second hole are intercrossed but not communicated. According to the heat accumulating type heat exchanger, residual heat in the cement manufacture is fully utilized, the heat exchange efficiency is maximized, the energy is saved and the goals of environmental protection and energy conservation 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...
