Description
Technical field
The present invention relates to a kind of spray tower tower tray device, the board-like spray tower internals as using on industrial production belong to the industrial equipment technical field.
Background technology
tower is widely used in chemical industry, pharmacy, the rectification and purification of the field of industrial productions such as food, absorption and separation, the unit operations such as evaporation and concentration, the kind of tower is divided into plate column and packed tower, plate column is to be applied to the earliest industrialized a kind of tower, comprise bubble-cap, sieve aperture, float valve, the various structures forms such as vertical sieve aperture, plate column is compared with packed tower, has operating flexibility large, stable operation is reliable, mass transfer parts easy to clean on column plate, be convenient to arrange the liquid cools heat sink, be convenient to arrange the advantages such as a plurality of side line feed inlet and outlets, therefore, at present still in extensive use, but the shortcomings such as the pressure drop of plate column ubiquity is large, plate efficiency is lower.although all belong to plate column, but vertical sieve aperture class column plate and bubble-cap, sieve aperture, float valve class column plate are essentially different again, bubble-cap, sieve aperture and float valve class column plate, the gas-liquid two-phase on column plate is all meet or contact in the cross-flow mode, the hydrodynamics operating mode of two-phase belongs to foam bubbling type, vertical sieve aperture class column plate belongs to jetting type tower plate, and jetting type tower plate is gas-liquid two-phase and stream, has increased gas load, has strengthened the contact of two-phase, jetting type tower plate is divided into again the various ways such as tongue type column plate, perform tray, slant-hole tray, combined trapezoid spray tray, vertical sieve aperture is a kind of structural shape of jetting type tower plate, according to the data introduction, to be developed in 1963 to nineteen sixty-eight by Mitsui Ship-building Company (MSE) the earliest, be characterized in that perforate (has circle on column plate, square hole, rectangular opening), arrange the circle that matches on the hole, square, the mass-and heat-transfer calotte of rectangle, circular, square, the calotte of rectangle is fixed on column plate, have difform hole on the sidewall of calotte, leave the gap between the bottom of calotte and column plate, each hole and supporting calotte have just formed an independently mass-and heat-transfer unit, liquid receiving area and liquid-droping groove are arranged in the both sides of column plate, liquid receiving area is substantially the same with setting and the common column plate of downspout.The efficient of calotte structure influence mass transfer unit, calotte bottom establish the gap so that liquid communication, and top blind flange rises and stops the gas-liquid mobilization that makes progress, and the circular hole of opening on cover body and column plate, square hole, rectangular opening are fixing with one heart, are triangle or rectangular arranged on column plate.Such structure can make the Liquid Flow on column plate be spray regime, and with and flow contact form.1971 U.S. fractionation company (FRI) measure to assert, this column plate with bubble-cap, sieve aperture, float valve class column plate is compared has the characteristics such as disposal ability is large, mass transfer effect good, pressure drop is low, be widely used at present.
although the vertical sieve aperture class jet tray of said structure has lot of advantages, but there are two large subject matters: the one, gas passes the calotte requirement very high gas flow rate, calotte stability circular, square or rectangle is very poor, must leave the gap between calotte and column plate simultaneously, so its connected mode can only be taked locally-attached form, this version causes the stability of calotte poorer, when gas speed changes suddenly, the violent phenomenon of vacillating now to the left, now to the right can appear in calotte, very easily causes calotte to come off, in actual applications, the phenomenon that calotte comes off is very general, and in a single day calotte comes off, and the mass-and heat-transfer efficient of column plate can descend rapidly, the 2nd, liquid receiving area and liquid-droping groove are arranged in the left and right sides of column plate, it is shaped as arc, occupied the very large area of column plate, liquid flows to the process of liquid-droping groove from liquid receiving area simultaneously, there is more serious stagnant area, mixed flow region etc., air-teturning mixed phenomenon is comparatively serious, the middle part flow velocity is fast, the both sides flow velocity is slow, the liquid of both sides time of staying on column plate is longer, the CONCENTRATION DISTRIBUTION of liquid on column plate is chaotic, do not form the concentration gradient on certain streamwise, part liquid does not contact with gas and carries out the heat and mass transport reaction, directly flow to liquid-droping groove by liquid receiving area, cause the mass transfer of liquid on column plate, heat transfer efficiency is restricted, although each air rising hole and supporting calotte form mass-and heat-transfer unit has very high efficient, but the efficient of whole column plate is not high.
in recent years, people are a lot of to research and the improvement of vertical sieve tray, but the two large problems that the above vertical sieve aperture class jet tray exists does not have solution fundamentally, as China Patent No. 99200122.6, 200620025314.8, 200620081465.5, 200820075320.3, 201010300365.8, 201220250049.9, 201210404542.6 etc., these improvement, air rising hole on column plate adopts remains circular hole, square hole or rectangular opening, improvement and the optimization just carried out on the calotte structure, the efficient of the mass-and heat-transfer unit that has improved that single air rising hole and supporting calotte form, fundamentally do not solve the calotte poor stability, easily come off, the problems such as plate efficiency is low, the somebody has designed and has separated stream without the back-mixing jet tray, as described in China Patent No. 201210513678.0, every layer arranges two tower trays in up and down and combines one deck column plate, and supporting a plurality of downspouts are set, be greatly improved aspect the solution liquid dispersion, but this tower plate structure is very complicated, the investment large, overhauls and clean very inconvenient, the advantage of plate column has been subject to restriction, and range of application is restricted.
Summary of the invention
