Abstract
The invention discloses a large-scale tube array graphite heat exchanger for extruding graphite tubes by using modified resin. The invention has reasonable structure, good heat transfer effect, convenient maintenance and good sealing effect between the tube plate and the shell.
Description
Technical field:
The present invention relates to a kind of graphite heat exchanger.
Background technology:
Existing large-scale tubular graphite heat exchanger, tubulation adopts the common graphite pipe, and heat-transfer effect is undesirable, seal by plane packing seal form between its tube sheet (comprising fixed tube sheet, floating tubesheet) and the housing, and utilize holddown spring to seal, easily reveal, and the maintenance trouble.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, the large-scale tubular graphite heat exchanger that heat-transfer effect is good with modified resin extruded anisotropic graphite pipe.
Technical solution of the present invention is:
A kind of large-scale tubular graphite heat exchanger with modified resin extruded anisotropic graphite pipe comprises housing, tubulation, tube sheet, it is characterized in that: tubulation adopts the phenol-formaldehyde resin modified graphitic pressed pipe.
Described tubulation is the phenol-formaldehyde resin modified graphitic pressed pipe of handling through temperature in 300 ℃, and its heat endurance and chemical stability are all improved, and linear expansion coefficient reduces greatly.
The sealing of " O " type circle is adopted in tube sheet and housing junction.
" O " type circle is arranged on the outer circumference surface of tube sheet.
Tube sheet adopts flush type conical surface adhesive form to be connected with tubulation.
The stringing mode of tubulation on tube sheet is that equilateral triangle is arranged, and the spacing between tubulation is 59mm, can increase the circulation flow velocity of shell side, has improved heat transfer coefficient, has guaranteed the compactedness of heat exchanger simultaneously.
The present invention is rational in infrastructure, and heat-transfer effect is good, good sealing effect between easy to maintenance, tube sheet and the housing.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of one embodiment of the invention.
Fig. 2 is the enlarged drawing of I portion among Fig. 1.
Fig. 3 is the enlarged drawing of II portion among Fig. 1.
Fig. 4 is the enlarged drawing of III portion among Fig. 1.
The specific embodiment:
A kind of large-scale tubular graphite heat exchanger with modified resin extruded anisotropic graphite pipe comprises housing 1, tubulation 2, fixed tube sheet 3, floating tubesheet 4, and tubulation adopts the phenol-formaldehyde resin modified graphitic pressed pipe.Described tubulation is the phenol-formaldehyde resin modified graphitic pressed pipe of handling through temperature in 300 ℃.Fixed tube sheet 3, floating tubesheet 4 and housing junction adopt " O " type circle sealing 5,6 respectively.Fixed tube sheet 3, floating tubesheet 4 adopt flush type conical surface adhesive form to be connected with tubulation 2.
