Description
Technical field
The utility model is related to relevant device field more particularly to a kind of fixing seal knots for air preheater of generating electricity
Structure.
Background technology
Currently, in sending out point process, need to preheat air, but existing pre-heating device is carrying out hot friendship to air
During changing, it is easy to happen leakage, and heat exchange effect is bad, it would be highly desirable to improve.
Utility model content
The main purpose of the utility model is to provide a kind of fixing seal structures for air preheater so that air
Heat exchange effect is good, and will not leak, and service life of equipment is elongated.
To achieve the above object, the utility model provides a kind of fixing seal structure for air preheater, including cylinder
Shell, support column, upper cover plate, lower cover, the polylith heat-conducting plate of shape, support column one end is fixedly connected with upper cover plate, the other end is fixed
Lower cover, shell one end fixed cover plate are connected, one end fixes lower cover, shell, support column, upper cover plate, lower cover is made to be formed
Cyclic annular mother's chamber, support column are coaxially disposed with shell, and heat-conducting plate is fixedly connected with upper cover plate, tubular shell, lower cover, support column, more
Female chamber is divided into multiple independent sub- chambers by block heat-conducting plate, and on the section of support mast axis, all sub- chambers are transversal
The fan annular of area equation, the first sealant coat inner walls and upper cover plate part and lower cover part so that first is close
Sealing seals up the seam between heat-conducting plate and shell and the seam between upper cover plate and shell and between lower cover and shell
Seam；Second sealant coats support column lateral wall and upper cover plate part and lower cover part so that the second sealant is close
Seal the seam between heat-conducting plate and support column and the seam between upper cover plate and support column and between lower cover and support column
Seam.
Preferably, including block heat-conducting plate.
Preferably, several air inlets and gas outlet are opened up on upper cover plate and/or lower cover so that an air inlet and one
Same sub- chamber of gas outlet connection.
The advantageous effect of the above-mentioned technical proposal of the utility model is：
Greatly increase heat exchange area so that heat exchanger effectiveness is splendid, in heat exchanging process, between each adjacent sub- chamber
Gas will not leak, environmentally friendly, and service life of equipment greatly increases.
Description of the drawings
Fig. 1 is the fixing seal structural schematic diagram that the utility model is used for air preheater.
Fig. 2 is the fixing seal structural schematic diagram that the utility model is used for air preheater.
Specific implementation mode
To make the technical issues of solving, technical solution and advantage clearer, below in conjunction with Fig. 1,2 and specific implementation
Example is described in detail.
A kind of fixing seal structure for air preheater, including the shell 1 of tubular, support column 2, upper cover plate 3, lower cover
Plate 4, polylith heat-conducting plate 5,2 one end of support column is fixedly connected with upper cover plate 3, the other end is fixedly connected with lower cover 4, and 1 one end of shell is solid
Determine upper cover plate 3, lower cover 4 is fixed in one end, and shell 1, support column 2, upper cover plate 3, lower cover 4 is made to form cyclic annular female chamber, support column 2
It is coaxially disposed with shell 1, heat-conducting plate 5 is fixedly connected with upper cover plate 3, tubular shell 1, lower cover 4, support column 2, polylith heat-conducting plate 5

Seal up seam between the seam between heat-conducting plate 5 and shell 1 and upper cover plate 3 and shell 1 and lower cover 4 and shell 1 it
Between seam；Second sealant 7 coats 2 lateral wall of support column and 3 part of upper cover plate and 4 part of lower cover so that second is close
Sealing 7 seals up seam and lower cover 4 between the seam between heat-conducting plate 5 and support column 2 and upper cover plate 3 and support column 2
With the seam between support column 2.Including 36 pieces of heat-conducting plates 5.Several air inlets and outlet are opened up on upper cover plate 3 and/or lower cover 4
Mouthful so that same sub- chamber of an air inlet and a gas outlet connection.
Greatly increase heat exchange area so that heat exchanger effectiveness is splendid, in heat exchanging process, between each adjacent sub- chamber
Gas will not leak, environmentally friendly, and service life of equipment greatly increases.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, under the premise of not departing from principle described in the utility model, several improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
