Abstract
The utility model relates to a column tube type graphite tube heat exchanger, which aims to solve the problems of difficult process and installation, easy leakage, no method of repairing equipment, etc. The utility model is characterized in that parts of both ends of a graphite tube inserted in a tube plate are sealed by fluoroelastomer sleeves which are of a hollow cylinder shape, and one end of each fluoroelastomer sleeve is provided with a round boss. The fluoroelastomer sleeves are arranged in a tube hole of the tube plate at one end of the heat exchanger so as to cause the boss to be embedded in an annular groove of the tube hole and overlapped on the plate surface of the tube plate on the tube plate at the other end; the graphite tube penetrates through two fluoroelastomer sleeve holes. The utility model can be used for occasions that acid and alkali corrosiveness medium needs heat exchange.
Description
The utility model relates to a kind of tube-type graphite heat exchange of heat pipe.
Existing tube-type graphite heat exchange of heat pipe, be to adopt clay to connect and seal between tube sheet and graphite-pipe, processing technology requires very strict, the error in length of graphite-pipe must not be greater than 2 millimeters, the consumption of the connection sealing place clay of graphite-pipe and tube sheet must strictly be controlled, otherwise can squeeze broken graphite-pipe or cause leakage.In the use because of the difference of the coefficient of expansion between graphite-pipe, tube sheet and the clay three, and cause graphite-pipe fracture or clay to crack and can't use, after this thing happens, can only adopt the way of plugging plate hole, the plug-hole clay needs 48 hours ability to solidify, and this not only has a strong impact on production, also greatly reduce the efficient of equipment, tube plug too much, have a strong impact on result of use, can only cause equipment scrapping.
The purpose of this utility model is to provide a kind of processing simple, and installation, maintenance is convenient, service-strong tube-type graphite heat exchange of heat pipe.
The utility model is achieved in that a kind of tube-type graphite heat exchange of heat pipe.It comprises end socket, graphite tube plate and graphite-pipe, the part of tube sheet is inserted by the sealing of fluorubber cover in the graphite-pipe two ends, the fluorubber cover is hollow garden cylindricality, one end has garden shape convex, the pore of tube sheet is stairstepping, the heat exchanger wherein counterbore inwall of an end tube sheet has the garden annular recess, the fluorubber cover is put into counterbore makes convex be embedded into groove to realize axial location, the tube sheet of the heat exchanger other end, the fluorubber cover is put into counterbore, convex is taken on the plate face of tube sheet, and graphite-pipe passes from two fluorubber trepannings, and the fluorubber cover is pressed on the tube sheet counterbore wall.
The utility model has the advantages that: 1. do not have strict size constrained relation between tube sheet counterbore, graphite-pipe and the fluorubber cover three, therefore processing is simple.2. owing to be to carry out resilient connection by the fluorubber cover between tube sheet and the graphite-pipe, therefore, graphite-pipe can be installed separately one by one, therefore installs easily.And prior art, all graphite-pipes and tube sheet must once strictly be located, and just can not move as long as the clay of a graphite-pipe solidifies other again.3. owing to be dismountable resilient connection between tube sheet and graphite-pipe, rather than the rigid attachment of solidifying, so maintenance is easily.4. owing to replace clay with fluorubber cover and connect the operating temperature that can make heat exchanger and mention 160 ℃ from 120 ℃, make operating pressure bring up to 0.55MPa from 0.3MPa.5. the service life of equipment and service efficiency obviously improve.
Fig. 1 is the schematic diagram of tube-type graphite heat exchange of heat pipe.
Below in conjunction with embodiment the utility model is described further.
The tube-type graphite heat exchange of heat pipe, comprise end socket 4, graphite tube plate 1, graphite-pipe 3, the part of tube sheet 1 is inserted by 2 sealings of fluorubber cover in graphite-pipe 3 two ends, fluorubber cover 2 is hollow garden cylindricality, one end has garden shape convex, and the pore of tube sheet 1 is stairstepping, and the heat exchanger wherein counterbore inwall of an end tube sheet 1 has the garden annular recess, fluorubber cover 2 is put into counterbore makes convex be embedded into groove to realize axial location, the tube sheet 1 of the heat exchanger other end, fluorubber cover 2 is put into counterbore, and convex is taken on the plate face of tube sheet 1, graphite-pipe 3 overlaps 2 holes from two fluorubber and passes, and fluorubber cover 2 is pressed on the tube sheet 1 counterbore wall.
