Kiln waste heat utilization system

Abstract

The invention relates to a kiln waste heat utilization system, which comprises a remote heat collection system, a mixing system, a conveying system and a dehumidification system. One end of an air pipe in the remote heat collection system is connected with a kiln waste heat collection air pipe, the other end of the air pipe is communicated with a mixing chamber of the mixing system, the mixing chamber is communicated with an induced draft fan of a boiler, an air pipe of the mixing chamber is provided with a cold air gate, the outlet pipe of the induced draft fan of the boiler is communicated with a plurality of drying chambers through a conveying pipe of the conveying system, and the drying chambers are divided into a mold drying chamber close to a grouting area and a blank drying chamber outside the mold drying chamber and are communicated with a dehumidification pipe of the dehumidification system. By adopting the kiln waste heat utilization system, heat in hot air produced by a kiln can be reused for drying blanks and molds produced with the kiln, the waste heat can be effectively utilized, the energy can be saved, and the production yield of the kiln can be improved.

Description

technical field [0001] The invention relates to a waste heat utilization system, in particular to a kiln waste heat utilization system. Background technique [0002] During the production process of the roller kiln, the hot air generated carries a large amount of heat energy, the waste heat is not fully utilized, the layout of the waste heat pipeline is unreasonable, and the heating system of the grouting table is widely distributed, resulting in a large heat loss, resulting in a low utilization rate of the overall waste heat , The frequency of plaster mold grouting per shift is small (twice per shift). It is difficult to achieve the desired effect in production under the existing heat source. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kiln waste heat utilization system, which can re-use the heat energy in the hot air produced by the kiln for drying the body and mold produced by the kiln, so that the was...
