A ceramic energy-saving kiln with high-efficiency relay recovery of cooling waste heat

Abstract

The invention discloses a ceramic energy-saving kiln for recovering cooling waste heat in high-efficiency relay. Hot air blower; the slow cooling area is equipped with a slow cooling area outlet pipe, multiple slow cooling area air supply pipe groups, multiple slow cooling area outlet pipe groups, slow cooling area exhaust pipes and heat exchange fans; the rapid cooling area is equipped with Combustion-supporting fan, air supply supervisor and burner, the air supply supervisor is equipped with air supply pipe group in quenching area and air outlet pipe group in quenching area. By adopting the present invention, a pipeline structure for recovering hot air is formed in an efficient continuous and relay manner, and all the cooling heat when cooling ceramics at each stage is recycled and utilized, which significantly reduces the fuel consumption in the drying and firing process, and can also effectively reduce the impact of heat sources on Environmental pollution can also improve product quality.

Description

technical field [0001] The invention relates to the technical field of ceramic firing, in particular to a ceramic energy-saving kiln for efficiently relaying and recovering cooling waste heat. Background technique [0002] In the ceramic industry, ceramic products need to be sintered at high temperature through a kiln, cooled and shaped to achieve a certain strength for people to use. Ceramic products need to absorb heat during the firing process, and the heat needs to be released during the cooling process. [0003] In order to improve the cooling efficiency, the ceramic products are generally cooled by segmental cooling according to the characteristics of the ceramic products. The cooling zone of the existing horizontal kiln (such as roller kiln, tunnel kiln) is generally subdivided into a rapid cooling zone, a slow cooling zone and a tail cooling zone. Among them, the rapid cooling zone is the first cooling stage after high-temperature firing. The cold zone is the secon...
