Abstract

The invention discloses a cement rotary kiln with a high energy utilization rate. The cement rotary kiln comprises a rotary kiln, a kiln body arranged on the rotary kiln and capable of rotating, and abracket for supporting the kiln body; an afterheat recovery device is arranged on the rotary kiln; and the afterheat recovery device comprises a heat collecting cover arranged on the kiln body, and aheat collecting water pipe arranged in the heat collecting cover. Through arrangement of the heat collecting cover and the heat collecting water pipe, the effect of preferably absorbing heat dissipated from the kiln body is achieved, the secondary utilization of energy is realized, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial furnaces, in particular to a cement rotary kiln with high energy utilization rate. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns and lime kilns according to different processing materials; cement kilns are mainly used for calcining cement clinker, and are divided into two categories: dry production cement kiln and wet production cement kiln. [0003] However, the rotary kiln will consume a lot of capacity during the working process, and a lot of heat will be dissipated, resulting in a waste of energy, which is not conducive to environmental protection and energy saving and emission reduction. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the prese...
