Description

A steam drying device for formed gypsum board

technical field

The utility model relates to a steam drying device for formed gypsum boards, belonging to the field of steam heat source gypsum board production tools.

Background technique

In gypsum production, after the gypsum is molded and pasted on paper, it is necessary to dry the formed gypsum board to achieve complete solidification. The existing gypsum board drying device generally uses coal and natural gas as heat sources, and then passes through a heat exchanger. To perform heat exchange, so as to dry the formed gypsum boards. Based on years of relevant work experience and thinking, the applicant found that the existing devices have relatively large deficiencies. The specific performance is as follows: First, the baking room is relatively large and relatively long, and the final baking temperature in the cabin converted by the heat exchanger is 170 degrees Celsius, and it is difficult to increase the temperature, and the cost is relatively high, and the energy consumption is relatively high. At the same time, this temperature causes the baking time to be too long and the efficiency is low; Second, it does not take into account other forms of heat sources and how to convert the heat sources to the maximum, such as using hot steam from power plants and how to use hot steam more efficiently for steam drying of formed gypsum boards.

That is: there is a need for a shaped gypsum board drying device, which can use steam as a heat source, can make the baking room have a higher temperature, and improve the solidification efficiency of the shaped gypsum board.

Contents of the invention

The technical scheme of the utility model is: a steam drying device for formed gypsum boards, which includes a baking room, in which baking racks are arranged continuously, and a gypsum board baking layer is evenly distributed on the baking racks, Two layers of overlapping steam pipes are arranged on the lower surface of the gypsum board baking layer. The steam pipes are repeatedly arranged in an "S" shape on the lower surface of the gypsum board baking layer. The trachea is connected to the vertical air outlet pipe, and the lower end and the upper end of the vertical air outlet pipe are respectively provided with a condensed water discharge pipe and an exhaust pipe.

The pipe diameter of the above-mentioned vertical air outlet pipe is smaller than the pipe diameter of the vertical air intake pipe.

The upper and lower pipe diameters of the above-mentioned overlapping steam pipes are arranged alternately.

The upper end of the above-mentioned vertical air intake pipe is closed, and the steam pipes are evenly distributed on the pipe wall of the vertical air intake pipe. An air supply pipe is arranged at the lower end of the vertical air intake pipe, and an inverted "U"-shaped pipe is arranged on the air supply pipe. The lower end of the "U" shaped tube is provided with a condensate drain.

The above-mentioned connecting section between the steam pipe and the vertical outlet pipe is arranged obliquely, and the horizontal position of the connecting section and the connecting end of the steam pipe is lower than the horizontal height of the connecting position with the steam pipe.

The aforementioned condensed water drain pipe and exhaust pipe are respectively connected with the condensed water collecting tank and the tail gas recycling device.

Compared with the prior art, the utility model is a steam drying device for formed gypsum boards. A gypsum board baking layer is evenly distributed on the baking frame, and two overlapping steam pipes are arranged on the lower surface of the gypsum board baking layer. , after several tests, the overlapping placement of two layers of steam pipes on the lower surface of each gypsum board baking layer can make the temperature in the baking room easily reach 250 degrees Celsius, which is easier to increase than the existing heat exchanger conversion temperature, which can improve the solidification efficiency of the formed gypsum board;

The steam pipes are repeatedly arranged in an "S" shape on the lower surface of the gypsum board baking layer, which is conducive to making the baking temperature distribution of each gypsum board baking layer even;

The two ends of the steam pipe are respectively connected with the vertical air inlet pipe and the vertical air outlet pipe, and the condensed water discharge pipe and the exhaust pipe are respectively arranged at the lower end and the upper end of the vertical air outlet pipe, so that it is beneficial to discharge the steam after use , the condensed water is discharged from the lower end;

The pipe diameter of the vertical air outlet pipe is smaller than the pipe diameter of the vertical air inlet pipe. In this way, the exhaust of the vertical air outlet pipe is slower, which is conducive to the retention of hot steam in the distillation pipe and the increase of pressure, which is beneficial to releasing more heat. ;

The upper and lower pipe diameters of the overlapping steam pipes are arranged alternately, which is beneficial to the uniform temperature of the space around the steam pipes;

The upper end of the vertical air intake pipe is closed, the steam pipes are evenly distributed on the pipe wall of the vertical air intake pipe, the lower end of the vertical air intake pipe is provided with an air supply pipe, and an inverted "U" shaped pipe is arranged on the air supply pipe. The lower end of the inverted "U"-shaped pipe is equipped with a condensate discharge device, which can facilitate the discharge of condensed water generated in the air supply pipe and the vertical air intake pipe at the same time;

The connecting section between the steam pipe and the vertical outlet pipe is arranged obliquely, and the horizontal position of the connecting section and the connecting end of the steam pipe is lower than the horizontal height of the connecting position with the steam pipe, which is conducive to the downward flow of condensed water generated in the steam pipe into the vertical in the trachea;

The condensed water drain pipe and the exhaust pipe are respectively connected with the condensed water collecting tank and the tail gas recycling device, so that the condensed water and steam tail gas can be effectively recycled.
