The bracing frame of restraining in extraordinary heat exchanger
Technical field
The utility model relates to extraordinary technical field of heat exchangers, is specifically related to the bracing frame of restraining in extraordinary heat exchanger.
Background technology
Heat transferring medium in the shell-side cylinder of extraordinary heat exchanger is Powdered, the structure of the bracing frame of restraining in traditional extraordinary heat exchanger is: plate body, plate body offers some pores and opening, tube bank is located in pore, and Powdered heat transferring medium circulates from opening.The defect that the bracing frame of restraining in traditional extraordinary heat exchanger exists is: adopt the structure offering opening on plate body, plate body beyond pore and opening can be formed the flowing of Powdered heat transferring medium and hinder, the structure of therefore traditional bracing frame easily causes the blocking of Powdered heat transferring medium, causes extraordinary heat exchanger to be difficult to normal work; In addition, this kind of structure makes the circulation area of Powdered heat transferring medium less, and heat transfer effect is poor.
Utility model content
The purpose of this utility model is: provide a kind of circulation area that greatly can increase Powdered heat transferring medium, avoids Powdered heat transferring medium to be obstructed the bracing frame of restraining in the extraordinary heat exchanger of blocking.
For achieving the above object, the technical solution adopted in the utility model is: the bracing frame of restraining in extraordinary heat exchanger, comprise a central support tube, the lateral support pipe that the arranged outside of central support tube has some circles to be circular layout around central support tube, connecting plate is fixedly connected with between lateral support pipe adjacent in each circle, central support tube is adjacent between each lateral support pipe in outer ring and is all connected with connecting plate, and each lateral support pipe often in circle is adjacent between lateral support pipe close in outer ring and is all fixedly connected with connecting plate; Described connecting plate plate, central support tube, lateral support Guan Jun are arranged along powdery medium flow direction.
Further, the bracing frame of restraining in aforesaid extraordinary heat exchanger, wherein, the mouth of pipe at central support tube, lateral support pipe two ends is respectively groove.
Further, the bracing frame of restraining in aforesaid extraordinary heat exchanger, wherein, the length of central support tube, lateral support pipe is 50mm ~ 60mm.
Further, the bracing frame of restraining in aforesaid extraordinary heat exchanger, wherein, the thickness of every block connecting plate is 5mm ~ 8mm.
The utility model has the advantage of: heat exchanger tube is located in central support tube and lateral support pipe, Powdered heat transferring medium passes from the interval that connecting plate is formed, this structure substantially increases the circulation of Powdered heat transferring medium, and can effectively avoid Powdered heat transferring medium to be obstructed blocking in shell-side cylinder, for the normal work of extraordinary heat exchanger provides safeguard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bracing frame of restraining in extraordinary heat exchanger described in the utility model.
Fig. 2 is A-A schematic cross-section in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the bracing frame of restraining in extraordinary heat exchanger, comprise a central support tube 1, the lateral support pipe 2 that the arranged outside of central support tube 1 has some circles to be circular layout around central support tube 1, in the number of turns of lateral support pipe 2 outside central support tube 1 and often circle, the quantity of lateral support pipe 2 can be determined according to the tube bank of the diameter of heat exchanger shell pass cylindrical shell and heat exchanger tube.Connecting plate 3 is fixedly connected with between lateral support pipe 2 adjacent in each circle, central support tube 1 is adjacent between each lateral support pipe 2 in outer ring and is all connected with connecting plate 3, and each lateral support pipe 2 often in circle is adjacent between lateral support pipe 2 close in outer ring and is all fixedly connected with connecting plate 3; Described connecting plate 3, central support tube 1, lateral support pipe 2 are all arranged along Powdered heat transferring medium flowing direction.In order to the mouth of pipe place preventing Powdered heat transferring medium to be deposited in the two ends of central support tube 1 or lateral support pipe 2, in the present embodiment, the mouth of pipe at lateral support pipe 2 and central support tube 1 two ends is groove respectively.In order to ensure the intensity of whole bracing frame, in the present embodiment, the length of central support tube 1, lateral support pipe 2 is 50mm ~ 60mm, and the thickness of every block connecting plate 3 is 5mm ~ 8mm.
The utility model has the advantage of: heat exchanger tube is located in central support tube 1 and lateral support pipe 2, Powdered heat transferring medium passes from the interval that connecting plate 3 is formed, this structure substantially increases the circulation of Powdered heat transferring medium, and can effectively avoid Powdered heat transferring medium to be obstructed blocking in shell-side cylinder, for the normal work of extraordinary heat exchanger provides safeguard.
