Abstract
The utility model relates to a forced circulation evaporator with an element, which belongs to the evaporation equipment technology field. The utility model is characterized in that a heat exchange tube (3) in an evaporator heating chamber (2) is provided with an in-tube insert with a heat transfer enhancing action, which makes the fluid body flow in the heat exchange tube with a lower Reynolds number in order to reach the higher heat transfer coefficients, and simultaneously reduces the flowed friction of the fluid body and is conducive to saving power consumption.
Description
Affiliated technical field:
The forced-circulation evaporator that has enhanced heat transfer component belongs to the evaporation equipment technical field.
Background technology:
Traditional forced-circulation evaporator since have less scaling, under the low temperature difference, also can realize normal running, therefore in industrial production, be widely used.But owing to require bigger circulation rate, cause power consumption very high, influenced operation economy.
Summary of the invention:
The purpose of this utility model provides that a kind of insert improves the less turbulence of tube fluid in the pipe by being equipped with in the heat exchanger tube of heating clamber, forced-circulation evaporator than high heat transfer coefficient also can be provided under the situation less in circulation rate, that flow resistance is lower, reduce power consumption and equipment investment significantly.
The utility model is achieved through the following technical solutions: the utility model mainly is made of forced circulation pump, heating clamber, vaporization chamber and circulation pipe, in the heat exchanger tube of heating clamber insert is housed, heating clamber one end links to each other with the forced circulation pump discharge, the other end links to each other with vaporization chamber by mozzle, and the inlet of forced circulation pump links to each other with the bottom of vaporization chamber by circulation pipe.Feed liquid enters vaporization chamber through charging aperture, after circulation pipe, forced circulation pump enter the heating clamber heating, enter vaporization chamber again and carry out gas-liquid separation, indirect steam is discharged from the outlet on vaporization chamber top, the material that is not evaporated is recycled pump again with fresh feed liquid and sucks, so move in circles, realize the evaporation and concentration of material.
The specific embodiment:
Below in conjunction with drawings and Examples, the auspicious the utility model of stating.
Fig. 1, Fig. 2 and Fig. 3 are general structure schematic diagrames of the present utility model.
The utility model is made of forced circulation pump (1), heating clamber (2), mozzle (7), vaporization chamber (9) and circulation pipe (5).Insert (4) is housed in the heat exchanger tube of heating clamber (3), and insert is fixed with the frictional force of heat exchanger tube inwall or by welding by it.For external hanging type heating clamber (Fig. 1, Fig. 2), an end of heating clamber links to each other with the forced circulation pump discharge, the other end links to each other with vaporization chamber by mozzle, and vaporization chamber links to each other with the inlet of forced circulation pump by circulation pipe.For with the heating clamber (Fig. 3) of the concentric placement of vaporization chamber, an end of heating clamber links to each other with the forced circulation pump discharge, the other end directly links to each other with vaporization chamber, vaporization chamber links to each other with the inlet of forced circulation pump by circulation pipe.Feed liquid enters vaporization chamber through charging aperture (8), after circulation pipe, forced circulation pump enter the heating clamber heating, feed liquid enters vaporization chamber through mozzle, indirect steam is discharged from by the outlet (10) of vaporization chamber, the feed liquid that is not evaporated with merge through feed liquid that charging aperture enters after enter circulating pump through circulation pipe again, move in circles with this, finish the evaporation and concentration of feed liquid, finish liquid and discharge through finishing liquid outlet (6).
By insert in the pipe that the augmentation of heat transfer effect has been housed in the heat exchanger tube of heating clamber, improved the less turbulence when tube fluid flows, can realize high heat transfer coefficient and low fluid resistance under the low reynolds number, improve heat transfer coefficient, also reduce energy consumption simultaneously.
The utility model has obtained application in the evaporation and concentration of feed liquids such as rifamycin, xanthans, gasohol, heat transfer coefficient is by 200 original～370W/m
2℃ bring up to 460～750W/m
2℃.
