Drying system for gypsum boards without paper surface

Abstract

A drying system for gypsum boards without a paper surface belongs to the field of gypsum board production and comprises a gypsum board solidification plant, a solidification room conveying device, a drying tail gas conveying pipeline, a drying room, a fuel gas drying device, a fan, an air energy drying device indoor unit, an air energy drying device outdoor unit, a drying room conveying device, a drying room air outlet and a solidification room air outlet. The gypsum board solidification plant and the drying room are arranged side by side, and a roof is made of transparent materials and is a relatively closed space. The solidification room conveying device is installed in the gypsum board solidification plant and can convey gypsum boards from one end of the gypsum board solidification plant to the other end of the gypsum board solidification plant. The system has the characteristics of energy conservation and full utilization of solar energy and waste heat.

Description

technical field [0001] The invention belongs to the field of gypsum board manufacturing equipment, in particular to a paper-free gypsum board drying equipment used for producing paper-free gypsum boards. Background technique [0002] Paperless gypsum board is a new type of gypsum board newly developed to overcome the defects of paper-faced gypsum board. It has the advantages of low cost and convenient secondary decoration compared with paper-faced gypsum board; The existing gypsum board drying equipment has long drying time and high energy consumption, especially as the requirements of environmental protection policies become higher and higher. The cost of drying is relatively high. According to the current gas price, the cost of drying each square meter of plate is nearly 1 yuan. According to the annual output of 10 million square meters, the drying cost alone needs nearly 10 million yuan. , Moreover, in the case of a large number of gas applications, the supply of gas can...
