Description
The utility model is the rotary packed bed gas-liquid heat-transfer mass transfer apparatus of gas axial flow type, belongs to the gas-liquid heat-transfer mass transfer apparatus.Be particularly related to and utilize rotary packed bed generation centrifugal force to strengthen the device of gas-liquid two-phase heat and mass.
It mainly is fixed filling-material structure that present gas-liquid two-phase heat and mass apparatus structure has varied, traditional device, as drop and diaphragm type cooling tower etc.In these cooling towers, liquid film flows downward under the gravitational field effect from top to bottom.But since gravitational field a little less than, the liquid film flow velocity is very slow, the gas-liquid heat-transfer mass-transfer efficiency is low, and filler material consumption is many, equipment volume is big, investment is big; Aspect rotary packed bed gas-liquid mass transfer device, all adopt at present both at home and abroad gas-liquid two-phase along the move mode of mass transfer of packed bed radial counterflow, (application number is: 95214611.8) etc. to be called the Chinese patent of " donut thin plate filler revolving bed gas-liquid mass transfer reactor " as name, though its liquid film flow velocity is very high, mass transfer effect is good, but when handling the gas-liquid two-phase heat and mass of atm number, when operating as cooling tower, it is big and because rotary packed bed inner and outer ring gas flow sectional area great disparity is bigger that gas need overcome the vapour lock of centrifugal force field, gas speed in interior ring place is too high and cause the bigger problem of vapour lock, so this class device is not suitable for the operation of gas-liquid heat-transfer mass transfer of the atm number of cooling tower one class.
The purpose of this utility model is exactly low excessively in order to solve and overcome the liquid film flow velocity that existing gravitational field gas-liquid heat-transfer mass transfer exists, the gas-liquid heat-transfer mass-transfer efficiency is low, filler material consumption is many, equipment volume is huge, invest the rotary packed bed big and inner and outer ring gas flow sectional area great disparity of centrifugal force field vapour lock that exists of big and existing super gravity field, interior ring high cycle speed, vapour lock is bigger, be not suitable for the problem and the shortcoming of atm number gas-liquid heat-transfer mass transfer operation, research and design is a kind of both can to increase substantially the liquid film flow velocity, gas-liquid heat-transfer mass-transfer efficiency height, invest little, can avoid the centrifugal force field vapour lock again, gas cross section of fluid channel in packed bed is even simultaneously, vapour lock is little, the rotary packed bed gas-liquid heat-transfer mass transfer apparatus of gas axial flow type that is fit to atm number gas-liquid heat-transfer mass transfer operation.
The utility model is realized by following structure technology scheme: the structural representation of the rotary packed bed gas-liquid heat-transfer mass transfer apparatus of this gas axial flow type as shown in Figure 1, its key has reversible passage rotary packed bed of axial gas runner and flow channel for liquids radially, it is by casing 1, rotary packed bed 2, gas-liquid centrifugation layer 3, fan blade 4, radially sparge pipe 5, feed tube 6, collecting tank 7, motor 8, discharging tube 9 connects and composes jointly, its mutual alignment and annexation are: rotary packed bed 2 are installed on the central authorities of casing 1 with casing 1 coaxial inner conductor, gas-liquid centrifugation layer 3 places rotary packed bed upper end, fan blade 4 places the upper end of gas-liquid centrifugation layer, radially sparge pipe 5 is positioned at the inner axle heart of rotary filler layer 2, above-mentioned rotary packed bed 2, gas-liquid centrifugation layer 3, fan blade 4, radially sparge pipe 5 connects and composes rotary body and is positioned at casing 1 central authorities by same axle center is coaxial, feed tube 6 is fixed in the internal upper part of casing 1, the port of export of feed tube 6 is aimed at the radially top end opening of sparge pipe 5, collecting tank 7 is installed on the bottom of casing and is connected with discharging tube 9, and motor 8 is installed on the bottom of casing; Wherein, above-mentioned gas-liquid centrifugation layer is radial plate wing structure or porous, granulated filler structure, and gas flows vertically, and liquid radially separates.
The utility model is compared following advantage and beneficial effect with prior-art devices: (1) and existing cooling tower etc. fixedly filler are compared, the utility model employing centrifugal force field makes under the liquid film velocity ratio gravitational field and improves about ten times, can increase the about order of magnitude of gas-liquid two-phase heat and mass transfer coefficient, can reduce equipment volume and consumptive material significantly, reduce production costs; (2) with existing rotary packed bed comparing, airflow direction of the present utility model radially changes into axially from existing, overcome the bigger shortcoming of vapour lock that factors such as centrifugal force and packed bed inner and outer ring sectional area great disparity is big cause, made the utility model can be fit to the gas-liquid heat-transfer mass transfer operation process of atm number.
Below Figure of description is further specified as follows: Fig. 1 is the structural representation of the rotary packed bed gas-liquid heat-transfer mass transfer apparatus of this gas axial flow type.Among the figure: 1 is casing, and 2 is rotary packed bed, and 3 is gas-liquid centrifugation layer, and 4 is fan blade, and 5 are sparge pipe radially, and 6 is feed tube, and 7 is collecting tank, and 8 is motor, and 9 is discharging tube.
Embodiment of the present utility model is comparatively simple, by shown in Figure 1, adopt general process for machining method design processing component, we recommend its design parameter to be: rotary packed bed inner and outer ring footpath can be respectively φ 70mm and φ 300mm, it highly can be 200mm～300mm, rotary packed bed runner is web plate shape or porous media, nutty structure, behind good each parts of processing and fabricating, by described its interconnected relationship of top specification connection is installed, just can implements the utility model preferably.After fabrication and installation are finished, need do dynamic balance running in case when rotating at a high speed vibration excessive.The utility model that the above-mentioned parameter of recommending by us designs and produces under general rotating speed, can be handled the cooling of 2～5 tons of water.Running operating principle of the present utility model is: liquid injects radially sparge pipe 5 by feed tube 6, under action of centrifugal force, radially enter rotary packed bed 2 interior ring, and by interior hoop outer shroud Radial Flow, the transmission of making heat and quality with the air-flow of axial flow exchanges, then by external loop diameter to discharge, along entering collecting tank 7 under the enclosure wall surface current, discharge from discharging tube 9 again, in gas is drawn into from the air inlet of casing bottom, it is rotary packed bed to flow through up vertically again, through spreading behind the hot mass transfer with liquid, through gas-liquid centrifugation layer 3 the liquid mist is separated again, pump out outside the casing by fan blade 4 then.
