Description
Technical field
The utility model relates to a kind of heat exchanger, is a kind of through-type double tubesheet heat exchanger specifically.
Background technology
That proves along with domestic pharmaceutical industry new edition GMP gos deep into further, and new requirement is also made to energy-saving and cost-reducing by country simultaneously; And in pharmaceutical industry, heat energy is main, the most effective control of microorganisms means, satisfactory product is selected in production run process, not only require that this product can not become the place of microbial growth, meet hygienic requirements, also to require product reduction energy ezpenditure of changing products, finally can also reduce production cost, meet national energy-saving standard.
Heat exchanger majority is tube-plate type heat-exchanger on the market at present, the connected mode of its pipe and tube sheet can use the modes such as welding, expanded joint, and junction (weld seam or expanded joint face) can be reached there is enough intensity, to ensure, when running, there is stronger La Tuoli and more reliable tightness.
If but directly apply to pharmaceutical industry, there are problems, easily there is seepage in the junction of such as pipe and tube sheet, and when being used in pharmaceuticals industry, between tube side material and shell side medium, the bidirectional crossed pollution effect of seepage is particularly serious, may cause that material is by the gross defective causes a large amount of economic losses.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of through-type double tubesheet heat exchanger, primary side material is by flowing in the seamless steel pipe bundle of electropolishing process, secondary side medium passes through the outer tube runs of shell side in contrary direction, heat-exchanging tube bundle end adopts double tubesheet fastening, make shell side, tube side thoroughly separates, even if because the reason such as expanded joint, welding causes leaking, the medium of health side also can not be polluteed.There is certain distance between expanded joint tube sheet and welding tube sheet, form a unlimited structure, as monitoring of leakage point, primary side material and the bidirectional crossed pollution of secondary side medium can be prevented.In addition, complete emptying design avoids product contact side to occur dead angle, can the growing of preventing microorganism in advance, is easy to cleaning and sterilizing, meets up-to-date GMP definitely.
To achieve these goals, the technical solution of the utility model is as follows:
Through-type double tubesheet heat exchanger, comprise two outer shroudings, two welding tube sheets, two expanded joint tube sheets, two bellowss, shell side sleeve pipe, tube side interface, shell side interface, heat-exchanging tube bundle, two blast pipes, the two ends of heat-exchanging tube bundle are welded on a welding tube sheet respectively, an outer shrouding is provided with outside each welding tube sheet, a tube side interface is provided with outside each outer shrouding, be connected by bolt flange formula between corresponding outer shrouding with welding tube sheet, shell side sleeve pipe is arranged with outside in the middle part of heat-exchanging tube bundle, the two ends of shell side sleeve pipe are tightly connected respectively by an expanded joint tube sheet, the top of shell side sleeve pipe and bottom are also respectively equipped with a shell side interface, the position that on shell side sleeve pipe, each shell side interface is relative is respectively equipped with a blast pipe, shell side outside of sleeve is located at by described bellows.
As preferred embodiment, the utility model also comprises deflection plate, and deflection plate is disposed on heat-exchanging tube bundle.
As preferred embodiment, shell side jacket exterior is also provided with incubator.
The effect of bellows is: if the temperature difference between shell side and tube side is very large, arranging of bellows can reduce shell side and the stress welding tube sheet and heat exchanger tube junction.
Expanded joint tube sheet, when designing, it should be noted that reduce welding deformation, because welding deformation can causing hole and plate out of plumb, makes that intensity is swollen can not get a desired effect.
Heat-exchanging tube bundle selects the tubing of import ASME BPE standard, and BPE standard meets most one of standard of bio-pharmaceuticals industry now, meets the various requirement of pharmaceutical industry completely, such as material, electropolishing etc.
Preferred embodiment the most, arranges deflection plate in shell side as disturbing flow device, greatly improves effectiveness of heat exchanger, reduces the heat exchange area of product, the shortening heat interchanger time.
The utility model has the advantages that: primary side material is by flowing in the seamless steel pipe bundle of electropolishing process, secondary side medium passes through the outer tube runs of shell side in contrary direction, heat-exchanging tube bundle end adopts double tubesheet fastening, make shell side, tube side thoroughly separates, even if because the reason such as expanded joint, welding causes leaking, the medium of health side also can not be polluteed.There is certain distance between expanded joint tube sheet and welding tube sheet, form a unlimited structure, as monitoring of leakage point, primary side material and the bidirectional crossed pollution of secondary side medium can be prevented.In addition, complete emptying design avoids product contact side to occur dead angle, can the growing of preventing microorganism in advance, is easy to cleaning and sterilizing, meets up-to-date GMP definitely.
