And current graphite heat exchanger is global design, be not easy to maintenance and change, once wherein a part breaks down and just needs complete machine to change, cost and maintenance cost are very high.
Utility model content
The utility model is for defect and the deficiency of prior art, provide a kind of can be high pressure resistant, heat shock resistance, high heat-transfer performance, the compound graphite heat exchanger being convenient to maintenance and changing.
The technical solution of the utility model is:
A compound graphite heat exchanger, comprises cylindrical shell, upper cover, low head, described upper cover, with cylindrical shell, upper end be tightly connected; Described cylindrical shell lower end and low head are tightly connected; Described inner barrel is divided into upper, middle, and lower part, and top is piece cellular type graphite heat exchange unit piece; Distributing chamber is again mixed for medium in middle part; Bottom comprise tube-type graphite heat exchange unit joint and under the tube sheet that moves about; Described medium mixes the top and bottom of distributing chamber again and by joining of graphite ring coupling block cellular type graphite heat exchange unit piece and tube-type graphite heat exchange unit, saves respectively; The tube sheet that moves about under described connects described tube-type graphite heat exchange unit joint and low head by Elastic Bolts.
On the basis of above scheme, the quantity of described piece cellular type graphite heat exchange unit piece is some.
On the basis of above scheme, described tube-type graphite heat exchange unit joint quantity be some joints.
Top heat exchange structure is taked polylith or monolithic piece block hole type graphite heat transfer block, can bear larger impact; Bottom heat exchange structure is taked more piece or single-unit tube-type graphite heat exchange joint, with lower cost, obtains larger heat exchange area, is convenient to maintenance and changes; Top and the bottom heat exchange structure all adopts cellular structure, can directly to the unit damaging, change; Guaranteeing that, on heat transfer effect basis, outfit of equipment cost declines to a great extent simultaneously.
Medium mixes distributing chamber again can isolate cooling medium mobile between heat transferring medium and outside cylindrical shell, can make heat transferring medium within medium mixes distributing chamber again, carry out mixed distribution again simultaneously, strengthening mass transfer, heat transfer.
The tube sheet that moves about under described adopts the design of moving about, and by Elastic Bolts, connects tube-type graphite heat exchange unit joint and low head, avoids because temperature stress variation causes short graphite-pipe destruction seal failure and seepage.
On the basis of above scheme, described tube-type graphite heat exchange unit joint comprises fixedly graphite cake, graphite support column, short graphite-pipe and lower fixedly graphite cake, fixed graphite cake and the lower graphite support column that is fixedly fixedly connected with between graphite cake; Fixed graphite cake and lower fixedly between graphite cake elasticity connect short graphite-pipe.
Upper fixedly graphite cake, fixedly between graphite cake, there is a graphite support column down, avoid pressure to be all pressed on short graphite-pipe, damage short Graphtic heat exchanging pipe by pressure.
On the basis of above scheme, fixed graphite cake and fixedly connect short graphite-pipe by corrosion-resistant seal circle or clay elasticity between graphite cake down.
The beneficial effects of the utility model are: compound graphite heat exchanger of the present utility model, combine the advantage of piece cellular type and tube-type graphite heat exchanger, and product strength is high, can high pressure resistant, heat shock resistance; Heat transfer property is extremely superior, high efficient heat exchanging, and corrosion resistance is strong; Can change impairment unit piece, unit joint, maintenance is simple; Manufacturing cycle is short, and cost performance is high.The shortest effective length of original graphite-pipe is 3 meters, and yield rate cannot promote all the time, and the graphite-pipe that is shorter than 3 meters has to directly scrap, and forming rubbish cannot process, and is unfavorable for the utilization of resources and protection of the environment.The design of employing new construction, the graphite-pipe that is not shorter than 1 meter all can use, and graphite-pipe yield rate and utilization rate significantly promote, and product cost declines to a great extent.
