Below the further optimization of the utility model to such scheme:
Described baffle unit comprises its baffling circle be connected with tubular shell inwall, and keeping at a certain distance away in described baffling circle is provided with some rod baffle.
Further optimization: described baffling circle comprises the first baffling circle, the second baffling circle, the 3rd baffling circle and the 4th baffling circle that are circularly set successively.
Further optimization: some rod baffle in the first baffling circle keep at a certain distance away longitudinal setting, described some heat exchanger tubes intert the left side being arranged on adjacent rod baffle.
Another kind of to optimize: some rod baffle in the second baffling circle keep at a certain distance away horizontally set, described some heat exchanger tubes intert the downside being arranged on adjacent rod baffle.
Another kind of to optimize: some rod baffle in the 3rd baffling circle keep at a certain distance away longitudinal setting, described some heat exchanger tubes intert the right side being arranged on adjacent rod baffle.
Another kind of to optimize: some rod baffle in the 4th baffling circle keep at a certain distance away horizontally set, described some heat exchanger tubes intert the upside being arranged on adjacent rod baffle.
The utility model adopts such scheme, there is gap hardly in rod baffle and heat exchanger tube, in tube bank, the upper and lower, left and right of every root heat-transfer pipe are obtained for reliable support, and fundamentally change the flow condition of fluid, the lateral flow changing baffle heat exchanger is the axial flow being parallel to heat exchanger tube, thus eliminates the root producing liquid induced vibration.
The utility model adopts such scheme, has following beneficial effect:
1, because shell fluid is based on axial flow, shell side pressure drop is reduced;
2, compared with baffle heat exchanger, there is the heat-transfer character of higher shell side unit pressure drop and overall heat-transfer coefficient than K/ △ p;
3, in heat exchanger, there is not serious Stagnation zones and heat exchange dead band, heat exchange efficiency is high, and less scaling.Improve heat exchange efficiency.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
