Abstract
The invention discloses a ceramic liquid distributor, which is manufactured into one piece by using a ceramic material and comprises a basin-shaped distributor body (1), wherein vents (5) are formed in the distributor body at intervals; convection holes (3) are formed around the vents at intervals; the upper ends of the convection holes (3) are provided with overflowing openings (2); and a baffling groove (4) is formed on the lower end face of the distributor body around the convection holes (3). The ceramic liquid distributor is high in strength, high temperature resistance, acid resistance, alkali resistance and corrosion resistance, and the service life of the ceramic liquid distributor is more than 20 times higher than that of the conventional metal liquid distributor; the ceramic liquid distributor makes the components of the liquid uniformly distributed on an entire cross section of a tower, avoids generating channel flow, deflected flow and wall flow, relieves amplification effect and end effect and therefore ensures the efficiency of separation; meanwhile, lots of metal material can be saved, the production cost and use cost can be reduced, the structure of the ceramic liquid distributor is simple and the manufacturing and installation of the ceramic liquid distributor are convenient.
Description
Technical field
The present invention relates to the packed tower internals, especially relates to a kind of ceramic liquid distributor.
Background technology
Because stream, bias current and wall flow phenomenon can appear colluding in liquid flow in the tower packing layer, cause packed tower to produce enlarge-effect and end effect, thereby can reduce separative efficiency.Therefore big city arranges liquid distribution trough in packed tower, make liquid energy homogenising distribution liquid components on whole tower section by liquid distribution trough, prevent from colluding stream, bias current and wall flow phenomenon and produce, reduce the impact of enlarge-effect and end effect, thereby improve separative efficiency.At present, the liquid distribution trough that is used for packed tower mainly contains the metal liquid distributor of being made by sheet metal, although the metal liquid distributor can improve mass transfer, heating surface, improve the phase Contact, have preferably and collect, mix and evenly the distribute function of liquid and separative efficiency preferably, but in use there is following point in it: the one, and metal liquid distributor acid and alkali-resistance and corrosivity are relatively poor, for some strongly corrosion liquids, its metal liquid distributor easily corrodes, not only affect separative efficiency, and service life is short, and use cost is high; The 2nd, the metal liquid distributor need to consume a large amount of Thin Stainless Steel plate materials, makes trouble, and manufacturing cost is high.
Summary of the invention
For the problem that liquid distribution trough in the above-mentioned prior art exists, the invention provides and a kind ofly not only have preferably separative efficiency, and also good corrosion resistance, can increase the service life, reduce the ceramic liquid distributor of cost.
The technical scheme that the technical problem to be solved in the present invention is taked is: described ceramic liquid distributor forms with whole manufacturing of ceramic material, it comprises the distributor body that is basin shape, the interval is provided with passage in the distributor body, be provided with convection holes in the passage peripheral intervals, described convection holes upper end is provided with overfall, is provided with the choked flow groove in the distributor body lower surface of convection holes peripheral position.
Described liquid distribution trough body is formed by the ceramic material Integratively manufacturing of high-temperature firing, and its intensity is high, and high temperature resistant, acid and alkali-resistance, corrosion resistance are good, are difficult for broken and distortion, and load capacity is large, thereby long service life; For making in the packed tower liquid flow distribution even, reduce gas-flow resistance in the tower, guarantee up and down balance of the interior gas pressure of tower, improve the packed tower separative efficiency, some the passages that the aperture is larger are set in the distributor body, when fluid flow is larger, for gas-liquid convection being evenly distributed and keeping certain height liquid, be provided with overfall at convection holes, make in the packed tower and can keep equally distributed gas-liquid convection all the time, when liquid distribution trough is placed out-of-flatness, for preventing that liquid at distributor body bottom surface crossfire, is provided with the choked flow groove in the distributor body lower surface of convection holes peripheral position.
Ceramic liquid distributor of the present invention is mixed through ball milling by the Xinning mud of 20%wt, boundary's spoil disposal of 30%wt, Changsha mud, 15%wt Changning mud, East Lake mud of 11%wt and the feldspar of 9%wt of 15%wt, plus fiber element and tung oil, mediate and form pug, again that the pug pugging is agglomerating, old, extrude into the mud section, again with the pressure forming of mud section, microwave setting drying, make semi-finished product, semi-finished product are inserted in the kiln to fire at 800-1000 ℃ of lower integral heat insulation 10-20 hour form.
The present invention mainly applicable tower diameter uses at the packed tower below 1.5 meters, it is high that it not only has intensity, high temperature resistant, acid and alkali-resistance, corrosion resistance is good, can reach service life more than 20 years, ten times of existing metal liquid distributor service life, and can make liquid homogenising distribution liquid components on whole tower section, can not produce and collude stream, bias current and wall flow phenomenon, reduced the impact of enlarge-effect and end effect, thereby guaranteed separative efficiency, simultaneously can save in a large number metal material, reduced production cost and use cost, it is simple in structure, manufacturing and easy for installation.
Description of drawings
Fig. 1 is plan structure schematic diagram of the present invention,
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
In the drawings, 1, distributor body 2, overfall 3, convection holes 4, choked flow groove 5, passage.
The specific embodiment
In Fig. 1 and Fig. 2, described ceramic liquid distributor forms with whole manufacturing of ceramic material, and it is comprised of some dimensions series.Described ceramic liquid distributor comprises the distributor body 1 that is basin shape, in the present embodiment, distributor body 1 diameter is 600 millimeters, highly be 120 millimeters, to be provided with eight diameter of bores be 80 millimeters passage 5 at the interval in the distributor body, the passage lower end is concordant with the distributor body, the upper end is a little less than the distributor body, in the distributor body of passage periphery, be provided with 26 convection holes spaced apart 3, the convection holes diameter of bore is 38 millimeters, the convection holes lower end is concordant with the distributor body, the upper end is lower than the passage height, be provided with two overfalls 2 every convection holes upper end, the overfall height is not more than 1/3rd of convection holes height, overfall lower end and distributor chamber body bottom surface distance are 30 millimeters, be provided with the choked flow groove 4 of annular in the distributor body lower surface of described every convection holes peripheral position, choked flow groove cross section is circular arc, depth capacity is 5 millimeters, when the distributor body was inclined, liquid can accumulate in the choked flow groove and can be at the mutual crossfire in distributor body bottom surface.Quantity, diameter of bore and the distributing position of certain described passage and convection holes and overfall size and shape are looked the distributor body size and are determined.
