Waste heat recovery device for cement production in building field

Abstract

The invention provides a waste heat recovery device for cement production in building field. The waste heat recovery device comprises a top shell structure, a lower shell structure arranged below thetop shell structure, a rotating structure arranged in the top shell structure and a heat exchange structure arranged below the rotating structure; the top shell structure comprises a top shell, a connecting pipe arranged on the top shell and a water pump arranged on the connecting pipe; a first through hole is formed in the side face of the top shell; the upper end of the connecting pipe is aligned with the first through hole and is fixedly connected with the side face of the top shell; the lower shell structure comprises a lower shell; the upper end of the lower shell penetrates through the inner surface and the outer surface of the top shell and is fixedly connected therewith; a second hole is formed in the side face of the lower shell; and the lower end of the connecting pipe is alignedwith the second through hole and is fixedly connected with the side face of the lower shell. According to the waste heat recovery device for cement production in building field, a floating frame anda rotating frame are arranged, so that the floating frame can float on the water surface, the rotating frame is immersed in water, the water in the top shell can continuously enter the rotating framethrough a sixth through hole in the rotating frame, and the water can fully contact and absorb the hot air.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a waste heat recovery device for cement production in the construction field. Background technique [0002] As a common building material, cement has been widely used, but the production process of cement will generate a lot of waste heat. If the waste heat is not recycled, it will cause waste of energy, resulting in low energy utilization rate and not meeting the requirements of the current green environment. economic needs. The existing waste heat recovery device mainly absorbs heat into the water for storage or post-processing through water heat absorption, but this method has low heat absorption efficiency, and the waste heat recovery effect is not ideal, and the water flows after not completely absorbing the heat. Going away leads to low utilization of water resources and increases the cost of water heat absorption. [0003] Therefore, it is necessary to provide a new ...
