The corresponding first through hole 132 of tube sheet.One end of 132 supporting pipeline 150 of first through hole of front tube sheet in this way.The correspondence of back tube sheet
132 supporting pipeline 150 of first through hole the other end.
In present embodiment, the inner passage that can flow through pipeline 150 to preheating gas of preheater.Pipeline is flowed through in this way
150 inner passage it is vertical to the flow direction of preheating gas and the flow direction of heat source, heat source can be utilized as far as possible
Heating in the inner passage of pipeline 150 to preheating gas.
Preferably, as shown in Figure 1, tube sheet 130 has opening towards the tube sheet groove 133 outside preheater.First through hole
132 are arranged in the bottom surface of tube sheet groove 133.Preheater further includes the sealing plate 160 for the opening that tube sheet groove 133 is arranged in.
Sealing plate 160 is provided with and corresponding second through-hole 161 of first through hole 132.Pipeline 150 is arranged in the second through-hole 161 and first
Through-hole 132.Pipeline 150 and the second through-hole 161 are fully welded connection, and the opening of sealing plate 160 and tube sheet groove 133 is fully welded connection.By
This, the heat source that can be avoided in the inner space of cuboid leaks to the outer of preheater from the second through-hole 161 of sealing plate 160
Portion, and increase the bonding strength of sealing plate 160 and pipeline 150.
In present embodiment, preheater further includes being filled between the tube sheet groove 133 of tube sheet 130 and sealing plate 160
The corrosion-resistant filling member in space.As a result, corrosion-resistant filling member can further avoid the heat source in the inner space of cuboid from
The first through hole 132 of tube sheet 130 leaks to the outside of preheater.Preferably, corrosion-resistant filling member by casting glue or acidproof pours
Material is built to be made.Facilitate the sky corrosion-resistant filling member being filled between the tube sheet groove 133 of tube sheet 130 and sealing plate 160 as a result,
Between.In present embodiment, corrosion-resistant filling member is made of casting glue.
Preferably, as shown in Figure 12 to Figure 14, after tube sheet 130 goes out tube sheet groove 133 by bending technique bending by plate,
The interface being fully welded between connection bending edges is made.Avoid having gap between the interface between bending edges as a result,.
In present embodiment, as shown in Figure 1 to Figure 4, shown in Figure 13 and Figure 14, tube sheet 130 includes tube sheet side wall and tube sheet bottom wall.
The inner surface of tube sheet side wall and the inner wall of tube sheet bottom wall surround tube sheet groove 133, and the inner wall of tube sheet bottom wall is tube sheet groove
133 bottom surface.Tube sheet 130 includes tube sheet connection surface 131.Tube sheet connection surface 131 is the appearance of the tube sheet side wall of tube sheet 130

110 flanged joint surface 111 is bonded, and side plate connection surface 141 and flanged joint surface 111 are fully welded connection.As shown in figure 4,
The upper and lower ends of the side plate connection surface 141 of side plate 140 and the second column coating surface fitting of column 120, side plate connection table
The part in face 141 and the second column face of weld of column 120 are bonded and are fully welded connection.
In present embodiment, side plate connection surface 141 (side plate 140 and 120 connection surface of column and the side of side plate 140
The connection surface of plate 140 and hollow flange 110) not enamel processing.Other surface enamel of side plate 140 are handled.Thereby, it is possible to
Facilitate side plate 140 and column 120, while the welded connecting of side plate 140 and hollow flange 110, reduce side plate 140 and heat source
Contact metal surface, reduce corrosion of the heat source to side plate 140, increase the service life of preheater.
Preferably, the width dimensions of side plate connection surface 141 are 1-5mm.Further decrease side plate 140 as a result, with heat
The metal surface of source contact, further avoids side plate 140 and is corroded by heat source, increase the service life of preheater.
