Description
Affiliated technical field
The present invention relates to the mass transfer purification techniques in fields such as chemical industry and environmental protection, especially a kind of large eddy-flow column plate.
Background technology
To be Zhejiang University succeed in developing and at a kind of novel column plate of industrial acquisition extensive use, this column plate is difficult for obstruction because percent opening is big, and so disposal ability is big, pressure drop is low in early 1970s rotating stream tray.They have successively developed " plate-tubular construction " and " plate-vertebra structure " two kinds of multi-form rotating stream tray.(drawing) from " modern tower technology " high speed tower
Rotating stream tray is by cloth liquid blind plate, and swirl vane covers tube, collecting tank, and overflow pipe (awl) is formed.Produce when air communication is crossed blade and rotatablely move, liquid is assigned to each blade by blind plate and forms thin liquid layer, the air-flow that is blown out between blade is sprayed into small droplet, in swirling eddy, be subjected to centrifugal force to get rid of the pendular ring that Xiang Tabi forms rotation, and gravitate flow to collecting tank, flows on the blind plate of lower floor's column plate by overflow pipe (awl) again.In the eddy flow plate has to two kinds of mass transfer mixed type and export-oriented centrifugal separating types.The eddy flow plate technique plays a role in the tens kinds of different purposes in the whole nation, obtains the National Science conference fourth class and encourages in 1984.Chinese patent 94210374.2 " wet process of FGD dust arrester " is applied to filed of flue gas purification to rotating stream tray.
The rotating stream tray load is high, and pressure drop is low, and operating flexibility is used widely greatly, and particularly the tower of diameter phi 1000mm is widely used in absorption, gas-liquid transmission of heat by contact, demist, dedusting, and effect is remarkable.When column plate amplified, cracking of eddy flow plate increased along with the increase of diameter, and centrifugal force field dies down.To tower body hydrodynamics state, heat and mass regularity and enlarge-effect, still need and to promote (" middle nitrogenous fertilizer " 01 phase in 1987 " summary of major diameter round trip eddy flow plate cooling tower technology ") at big tower after further understanding fully." middle nitrogenous fertilizer " and 1994 02 phases " major diameter round trip rotating stream tray scrubber is in the application of Liu Huachang ", " Baogang's science and technology " 04 phase in 1999 documents such as " large-scale demist eddy flow plate are in the application of spray column " all takes round trip eddy flow plate to address this problem, the outer journey number of blade of round trip eddy flow plate is Duoed one times than interior journey blade, tower wall place blade pitgh can be dwindled, the distribution of gas-liquid with contact unlikely deterioration, still can guarantee higher mass-and heat-transfer efficient.The condensing tower diameter phi 3000mm of Shichuan Chemical Factory, the column for smoke purification diameter phi 6500mm of Sintering Plant of Baotou Steelworks.Can collection of thesis " design and research that rotating stream tray scrubber maximizes " (Chen Zhao of Hunan University should wait) have discussed station, national chemical Thermal Design technique center calendar year 2001 that the φ 5700mm of Handan steam power plant fume desulfurizing tower employing blade outer end diameter is respectively 2000mm, 3900mm and 5700mm three Cheng Xuanliu plates are handled 300,000 m
3/ h flue gas.
Because after rotating stream tray amplifies, eddy flow plate increases of cracking, and centrifugal force dies down, tower body fluidised form, the regular variation of heat and mass are bigger, and round trip and multipass eddy flow plate deleterious influence rotating stream tray scrubber maximization application.
Summary of the invention
In order to overcome the increase of cracking after rotating stream tray amplifies, centrifugal force dies down, and the problem of absorption, gas-liquid transmission of heat by contact, demist, dust removing effects variation the invention provides a kind of large eddy-flow column plate, can make the rotating stream tray diameter very big.
The present invention solves the technical scheme that its technical problem takes:
A kind of large eddy-flow column plate is clocklike arranged acting in conjunction by a plurality of standard type eddy flow plate clarifiers, and its collecting tank base plate is interconnected to the enclosed baffle of an integral body, and tower body is divided into two parts up and down, constitutes a large eddy-flow column plate; Air-flow is fitted on each standard type eddy flow plate clarifier synergy from large-size rotational flow column plate lower part, a plurality of large eddy-flow column plates are arranged above and below and form a large eddy-flow panel assembly.
Above-mentioned large eddy-flow column plate, its feature also is: several standard type inward turnings are mixed eddy flow plate clarifier and are constituted maximization quality transmission type rotating stream tray, several standard type outward turning separating spiral-flow plate clarifiers constitute maximization divergence type rotating stream tray, and maximization divergence type rotating stream tray is on large-scale plant top.
Above-mentioned large eddy-flow column plate, its feature also is: its horizontal section can be that circular, rectangle or other are close-shaped continuously arbitrarily.
Above-mentioned large eddy-flow column plate, its feature also is: individual layer large-size rotational flow column plate can be level, that tilt or stepped.
Above-mentioned standard type eddy flow plate clarifier, it is characterized in that: be provided with vertical ring baffle between the standard type outward turning eddy flow plate clarifier, in order to receive the drop of centrifugation, work to do cylindrical shell, be called " nominal cylindrical shell " or " justice tube ", justice tube section is decided with eddy flow plate clarifier arrangement mode, can be circular, square, regular hexagon.
Above-mentioned standard type eddy flow plate clarifier, it is characterized in that: eddy flow plate optimum diameter is 1～2 meter, generally is no more than 3 meters.
The invention has the beneficial effects as follows:
1. the present invention has thoroughly solved rotating stream tray maximization application problem, makes this load rotating stream tray high, that pressure drop is low, operating flexibility is big, purification efficiency is high that more wide application prospect arranged.
2. " the justice tube " of large eddy-flow column plate of the present invention makes large eddy-flow column plate can be used for the centrifugation of dedusting demist, uses more wide.
3. large eddy-flow column plate of the present invention has certain resistance, can make gas distribution more even, and the big more advantage of tower diameter is obvious more.
4. large eddy-flow column plate swirl vane of the present invention has two substandard cloth liquid functions, the gas-liquid mass transfer better effects if, and liquid-gas ratio can reduce greatly, thereby saves energy consumption.Because the gas-flow resistance of the reduction purifying column of liquid-gas ratio also reduces greatly, energy-saving effect is more obvious.
5. large eddy-flow column plate purifier of the present invention can build up rectangle, horizontal.
6. large eddy-flow column plate of the present invention can change by the mode that stops several standard type eddy flow plate clarifiers and adjust operational factor, makes system's operating flexibility bigger.
