A system and method for continuous production of daily-use porcelain based on waste heat classification and utilization

Abstract

The invention belongs to the field of daily-use porcelain production, and specifically discloses a daily-use porcelain continuous production system and method based on waste heat classification and utilization, which includes a front box of a dryer, a back box of a dryer, a kiln and a heat exchanger. Among them: the front box of the dryer is used for demoulding the blank, the rear box of the dryer is used for dehumidifying the demoulded blank; the kiln is used for firing the demoulded and dehumidified blank to obtain For daily-use porcelain, the flue gas produced during firing includes residual heat flue gas and moisture exhaust gas. The residual heat flue gas is used to provide heat for the dehumidification of the blank in the back box of the dryer to obtain wet flue gas. The exhaust gas enters the heat exchanger; the humid exhaust gas enters the heat exchanger from the front of the kiln, and the heat exchanger uses the heat of the exhaust exhaust gas and the wet flue gas to heat the dry air and preheat the low-temperature water. The air enters the front box of the dryer to provide heat for the front box of the dryer to release the blank. The invention realizes the uninterrupted continuous production of daily-use porcelain, and improves the production efficiency and energy utilization rate.

Description

technical field [0001] The invention belongs to the field of daily-use porcelain production, and more specifically relates to a continuous production system and method for daily-use porcelain based on waste heat graded utilization. Background technique [0002] With the improvement of living standards in modern society, people's material needs continue to increase. As daily necessities, daily-use porcelain is widely used because of its beautiful, hygienic and durable characteristics. In recent years, the demand in domestic and overseas markets has also been increasing. The production process of daily-use porcelain is mainly based on primary firing, secondary firing and tertiary firing. The firing temperature of daily-use porcelain usually needs to reach 1100°C to 1300°C, which consumes a lot of energy. In recent decades, in response to the requirements of environmental protection and energy efficiency and the improvement of the firing process, the firing fuel for daily-use ...
