Abstract

The invention provides a heat accumulation type heat exchanger for utilizing waste heat in the cement production process. The heat exchanger comprises heat accumulation material, first holes and second holes are formed in the heat accumulation material and are of multi-row structures, a row of second holes are arranged between every two rows of first holes, a row of first holes are arranged between every two rows of second holes, the first holes and the second holes are arranged to form an angle of 90 degrees, the distance between the centers of circles of every two adjacent holes in the same row of first holes is L2, and L2 and the diameter D1 of the first holes meet the relation that 1.5<L2 / D1<2.7. According to the solid material heat accumulation type heat exchanger, waste heat in the cement production process is fully utilized so that the heat exchange efficiency of the heat exchanger can be maximized, and thus energy is saved, and the purposes of environmental protection and energy conservation can be achieved.

Description

Technical field [0001] The invention involves a heat exchanger for the use of the waste heat of the efficient cement production process, which belongs to the F28D heat exchanger. Background technique [0002] The cement industry is a highly energy -consuming, high -pollution industry.The new method is a advanced cement production process.Cement's clinker is fired through dry method to reduce dehydration, thereby greatly reducing energy consumption. Therefore, advanced new dry-type cement production is 50%-60%of energy saving than wet production, but there is still a broad energy-saving space.In order to further improve the energy utilization efficiency of cement enterprises and reduce the cost of cement enterprises, the Ministry of Industry and Information Technology released the "Implementation Plan for the Promotional Promotion of Pure Low -temperature Heritage Power Generation Technology of New drying cement kilns" to promote the application of cement production line residual ...
