Han Zun medicine dedicated screw thread tube condenser

Han Zun medicine dedicated screw thread tube condensers Han Zun HZ Spiral Wrapping condenser heat exchangers is an efficient, small footprint, the new devices, especially the old system expansion not only can reduce the investment, and compact spiral wound structure is more advantageous equipment layout. Spiral Wrapping type heat exchanger has a heat sufficiently small difference in the characteristics of hot and cold side can not only save energy, but also can optimize systems and processes, has a good energy saving effect. ? ???? 1. Structure and performance characteristics of the structural characteristics ???? ???? 1.1 compared to the traditional shell and tube heat exchange tube bundle, ribbed tube heat exchanger spiral heat transfer tubes are in each of the helical structure by a certain law uniformly wound within the housing. This structure on the one hand to extend the length of the heat transfer tubes, heat sufficient; on the other hand has greatly changed the state of the fluid flow, and enhance the turbulence effects, and strengthen the heat. Meanwhile, the spiral wound elastic tube bundle design may have? Effect eliminate turbulence buffeting heat stress, heat stress, stress to achieve self-cancellation. ???? ???? Between 1.2 Features 1.2.1 highly efficient heat exchanger, saving ???? spiral heat exchanger layers of heat transfer tubes wound in opposite directions, this unique winding structure design, pole changing the flow of the ground state of a fluid,? form a strong turbulence effect within the housing, due to the strong flow of the helical tube? of effects, so that the heat transfer coefficient of the tube of film also increases, thereby increasing the? integrated heat transfer coefficient. In soft drinks such as steam heat exchange water conditions, often? Conventional shell and tube heat exchanger heat transfer coefficient k value is generally up to 6? 000? W /? (M2? ℃). SECESPOL heat the heat transfer coefficient k value of up to? 14? 000? W / (m? 2 ℃), is more than three times that of conventional shell and tube heat exchanger. ???? Because of its unique spiral winding structure, heat transfer tube bundle extend it? Length is 4 to 6 times the length of the housing, heating enables the heat medium in the heat transfer tubes? Long in the residence time also when condensation by cooling medium makes even more? fully, without going through the second heat, to ensure that the full exchange of heat, lifting? high energy efficiency, saving energy. ???? Thread elastic tube diameter 8? Mm, 10? Mm, 12? Mm? 3 kinds of wall? Thickness of only 0.6? Mm. ???? 1.2.2 Unique 90 ° connector with the ends of the two heat exchanger flange using 90 ° angle between the center axis of the connection, you can make all participate heat exchanger, leaving; automatic flushing fluid line, reduce clogging tendency for fluid cushion and reduce noise. Due to its unique 90 ° connection and screw thread structure, a unique surface treatment technology and media on both sides of the countercurrent heat exchanger, and therefore have a high flow rate (soda heat transfer process, the shell side of the design flow rate of water up to 5.5m / s ) ,? temperature gradient is small, dirt coefficient characteristics of small. Internal structure designed with acoustic resonance allowable guidelines (Eisinger? Bevins guidelines and criteria), effectively inhibited the acoustic standing wave vibration phenomenon, minimize operating noise and heat exchanger can be operated in a low noise condition. ???? 1.2.3 temperature, high pressure ???? screw thread tube heat exchanger heat transfer tube bundle and housing-wide use of stainless? Steel, with a uniform coefficient of expansion, not due to pressure and temperature instability deformation caused by the heat exchanger. Heat exchanger temperature, high pressure, no? To install pressure reducer, the maximum temperature 400 ℃, pressure 2.0? MPa. ? Use Owen (OWEN) principle of turbulence buffeting frequency standards, using the heat transfer tube bundle minimum clearance design, spiral wound elastic tube bundle approach effectively eliminates the thermal stress turbulence buffeting phenomenon, extending the life of the heat exchanger. 1.2.4 compact structure, small size and compact way ???? spiral wound structure to meet the conditions the same heat load?, This heat exchanger volume only the traditional shell and tube heat exchanger? About 1/10, covering small size, saving space. But also because of small size, light weight, easier installation, removal, reducing installation costs. ???? 1.2.5 low fouling tendency, easy to maintain due to the screw thread ???? tube heat exchanger winding tube design, the tube through the fluid in a spiral pattern, as well as reducing the possibility of fouling tendency of the wall surface, shell fluid through the wound crosswise counterflow tube adjacent the tube? between, continuous separation and confluence between the layers, so that the fluid turbulence strengthening housing, at the same flow rate also reduces the probability of precipitation, guarantee long cycle of the equipment, high-load operation. Spiral ribbed tube heat exchanger fouling tendency is very low, it does not mean that does not bear? Scale, once fouling phenomenon, since the equipment is relatively small, clean too? Very simple, usually by chemical cleaning methods, low concentrations prepared dilute nitric acid soak 2 ~ 3? h can be, low maintenance costs. ???? 2? Applications ???? Because screw thread tube heat exchanger advanced heat transfer technology, currently in a solvent condensate recovery domestic pharmaceutical raw materials and other fields are widely used. ???? Success Stories: Qilu Pharmaceutical, Cloud River Pharmaceutical, North China Pharmaceutical Huasheng, Wei Qi medicine, Worldbest Pharmaceutical, TUL and so on.
