Prefabricated brick for cement kiln and masonry method

Abstract

The invention provides a prefabricated brick for a cement kiln and a building method. The prefabricated brick for the cement kiln comprises a composite layer and a nano heat insulation layer, the composite layer comprises a working layer, a heavy supporting layer and a light heat preservation layer which are sequentially arranged, and the side, away from the heavy supporting layer, of the light heat preservation layer is bonded to the nanometer heat insulation layer. The composite layer is provided with an anchoring hole and a first anchoring groove, the nanometer heat insulation layer is provided with a second anchoring groove, and the anchoring hole, the first anchoring groove and the second anchoring groove are sequentially communicated. The composite layer is provided with a meshing part, and two adjacent prefabricated bricks for the cement kiln can be meshed and connected through the meshing part. The prefabricated brick for the cement kiln has the characteristics of good anti-skinning performance and light weight; the prefabricated bricks for the cement kiln are connected with the anchoring parts on the kiln wall in an anchoring mode through the anchoring holes, the first anchoring grooves and the second anchoring grooves, every two adjacent prefabricated bricks for the cement kiln are connected in a meshed mode through the meshing parts, assembly type building of the kiln lining body is achieved, the construction efficiency is improved, and the overall stability of the kiln lining body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a prefabricated brick for cement kiln and a masonry method. Background technique [0002] With the acceleration of urbanization in my country, the continuous increase in the total amount of garbage has become a social problem that plagues urban development, pollutes the urban environment, and affects the lives of residents. Cement kilns have become the main equipment for co-processing industrial, domestic and other hazardous wastes. Due to the existence of a large amount of harmful components such as sulfur, alkali and chlorine in the waste, the smoke chamber of the cement kiln is seriously crusted. Due to the frequent cleaning of the crust, the operation rate of the kiln is reduced. It takes a lot of heat to evaporate the water vapor to remove the crust in the smoke chamber with high pressure water. And increase the thermal energy consumption. [0003] In the prio...
