Embodiment 1

[0030] Such as figure 1 As shown, the present invention provides a gypsum board drying device whose heat source is natural gas, including several drying areas 1 connected in sequence, three drying areas 1 in the embodiment of the present invention. Drying area 1 is equipped with dryer 2, inside of which is equipped with air distribution chamber 3 for air circulation and conveying roller table 4 for conveying plasterboard, and conveying roller table 4 passes through different drying areas 1 in sequence The air distribution chamber 3, and the paper-faced gypsum board is dried by the hot air in the air distribution chamber 3. The air distribution chamber 3 is provided with an air distribution gate 301 for distributing heat to the roller table space. The air distribution chamber 3 is connected with a combustion chamber 5 , and a circulation fan 501 is arranged in the combustion chamber 5 , and the circulation fan 501 is used to realize the circulating flow of hot gas in the air d...

Embodiment 2

[0036] A kind of heat source is the drying process of the gypsum board of natural gas, it is characterized in that: comprise the steps:

[0037] S100, upper roller: place the gypsum board to be dried in layers on the conveying roller table 4 in the dryer 2;

[0038] S200, sequential drying: use the heat generated by natural gas combustion to heat the gypsum board on the conveying roller table 4 during operation, and the gypsum board passes through the first drying zone 101, the second drying zone 102 and the third drying zone 103 in sequence Carry out drying in different directions and at different temperatures; in this embodiment, the running speed of the conveying roller table 4 is controlled at 70-90 m / min. The temperature of the first drying zone 101 is controlled to be 170-220°C, the temperature of the second drying zone 102 is controlled to be 180-225°C, the temperature of the third drying zone 103 is controlled to be 90-125°C, and the chimneys in each zone of the dryer 2 ...

Abstract

An embodiment of the invention discloses a paperbacked plasterboard drying device with natural gas as a heat source. The device comprises a plurality of drying areas which are sequentially connected,wherein drying machines are arranged in the drying areas, an air distribution chamber and conveying roller beds are arranged in each drying machine, the conveying roller beds sequentially pass throughthe air distribution chambers of different drying areas, and an air distribution damper used for distributing heat to roller bed space is arranged in each air distribution chamber; each air distribution chamber is connected with a combustion chamber, and a circulating fan is arranged in each combustion chamber; a burner is further arranged in each combustion chamber, a gas feeding pipeline and anair feeding pipeline are arranged on each combustion chamber, each air feeding pipeline is connected with the corresponding circulating fan, and a gas feeding damper and an air feeding damper are arranged on each gas feeding pipeline and the corresponding air feeding pipeline respectively; chimneys are further arranged on the drying machines. A drying process comprises steps as follows: S100, feeding the paperbacked plasterboard to the roller beds; S200, sequential drying; S300, tail gas treatment; S400, discharging from the roller beds. According to the paperbacked plasterboard drying device, paperbacked plasterboard is dried with heat produced by natural gas in combustion, and equipment is simplified and pollution is reduced by contrast with a production process of a coal-fired plant.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board production, in particular to a drying device and drying process for gypsum board with natural gas as the heat source. Background technique [0002] Paper-faced gypsum board is a board made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the board core, and made of special cardboard as the surface protection. Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance, and simple construction method. Gypsum boards need to be dried during the production process, which generally improves the overall performance of the gypsum boards. Drying uses coal or electromagnetic waves to generate heat to dry the plasterboard. [0003] For example, the patent number is: 201610194694.6, and the patent name is an invention patent of an electromagnetic microwa...
