Abstract
The present invention relates to a splash plate type overflow device which is applied to wet desulphurization and dust-removing devices of environmental protection industry and centrifugal or absorption towers of chemical industry, etc. to form annular or square overflow grooves so as to form required liquid membranes. The present invention can ensure the stability of the device performance; the splash plate type overflow device has the advantages of even overflow, scale prevention, clogging prevention, deposition prevention, air leakage prevention, splash prevention, etc., has preferable technical performance and reliability of easy examination, easy maintenance, etc. after the operation of the devices, and can solve various problems of the existing overflow groove during the operation of the devices.
Description
(1) technical field
The invention belongs to environmental protection equipment.
(2) background technology
The wet method sulphur removing and dust removing equipment in the past and the overflow launder of chemical tower, existing liquid stream easily to produce to contain in fouling and the liquid stream slag particle to produce deposition causes equipment to stop up, the overflow launder of different structure exists the easy access arrangement of outside air inside to cause liquid miscarriage life to be splashed, bring equipment to be in operation simultaneously and produce the principle confusion, changed the bad phenomenon such as main performance of equipment even.Find the deficiency of prior art splash board type overflow mechanism by long research and test, and solve the variety of issue that overflow launder in the past exists when equipment moves.
(3) summary of the invention
The objective of the invention is to develop a kind of novel splash board type overflow mechanism.
Splash board type overflow mechanism of the present invention, mainly spattering plate portion 1, barrel part 2 and cylindrical shell 3 by hydrojet forms, hydrojet spatters plate portion 1 and barrel part 2 adopts integral body or combining structure, spatter gapped e between plate portion 1 and the barrel part 2 in hydrojet, form spill cavity, feed flow hole h is arranged on the barrel part 2, feed flow hole h has inlet g and penetrates liquid mouth i, penetrate liquid mouth i and spatter plate portion 1 facing to hydrojet, hydrojet is spattered and is formed liquid outlet f between plate portion 1 and the cylindrical shell 3.
Hydrojet spatters plate portion 1 and barrel part 2 can adopt integral body or combining structure, hydrojet is spattered plate portion 1 connection or is fixed on cylindrical wall part 2 (comprising on the square barrel), spatter plate thickness ay, determine according to material, if it is a granite material, it is 350-10mm that hydrojet is spattered plate portion thickness, if it is metal and synthetic material, then to spatter the thickness of plate be 350-0.5mm to hydrojet; The length ah that hydrojet is spattered plate portion is 800-300mm; What hydrojet was spattered plate portion 1 and cylindrical shell 3 liquid outlet f spatters Ban Yanjiao cutter angle.The positive pitch α (or spattering plate along flat mouthful of limit plane annular circle) that it spatters the outside (being cylindrical shell 3 inboards) of plate guides liquid into the outer generation when preventing fluid and splashes.Cylindrical shell 3 spatters plate portion 1 inboard inferior horn fluid place with hydrojet, its cylindrical shell 3 inwalls are provided with the downward angle of inclination beta of the gradient, prevent that hydrojet from spattering between plate portion 1 and the barrel part 2 the liquid direct current of discharging annular or square and special-shaped overflow gap when feed flow hole h jet produces atomizing, the ad hoc liquid that is changed to evenly produces the liquid film overflow and falls.
The gap e that hydrojet is spattered between plate portion 1 and the barrel part 2 is that designing requirement does not wait according to the liquid liquid outlet quantity, and its gap e is 50-0.5mm.Liquid outlet f and hydrojet are spattered plate portion correlation centre-height position c and can not waited by flow stream pressure and flow and specification requirement; Feed flow hole h in the quantity of the annular circumferential or the square length of side and distribution and hole in the heart angle Φ (or distance between centers) determine by liquid supply pressure and integral layout (1500-100mm) requirement; In addition, according to the specification requirement difference, but inlet g point vertical direction moves to g1 or g2 point, horizontal direction moves to g3 or g4 simultaneously, to form different vertical direction spray angle ω and horizontal direction spray angle Ψ, promptly penetrate the center line of liquid mouth i and feed flow hole h and plane that hydrojet is spattered plate portion 1 and be not restricted to vertical orientations among Fig. 2, with flow stream pressure and hydrojet spatter between plate portion 1 and the barrel part 2 apart from e and device structure shape difference, can change design and penetrate the center line of liquid mouth i (or feed flow oral pore h) spattering the orientation of board plane, make its vertical direction with spray angle ω or horizontal plane on the direction oblique impact of 5 °-175 ° of spray angles, also can change the angle that plate 1 is spattered in design simultaneously.The structure that plate portion 1 and barrel part 2 are spattered in setting can adopt and be made as integral body or join installation.Its cylindrical shell 3 selections are to adopt granite or wear-resisting, heatproof, anticorrosion etc. about nonmetal and hard synthetic material, the also corresponding difference of cylindrical shell thickness d by the difference requirement.
Splash board type discharge device of the present invention is applied to the wet method sulphur removing and dust removing equipment and the chemical tower of environmental protection industry (epi), and looping or square polyrrhea groove are to form the liquid film that requires.
Succeeding in developing of splash board type discharge device of the present invention can guarantee that equipment performance is stable, and it is even that splash board type overflow mechanism has overflow, good antiscale property, anti-clogging, anti-deposition, anti-leaking out, anti-advantage and equipment such as splash is easily checked technical performance that easy care etc. are superior and reliability after operation.
(4) description of drawings
Fig. 1 is embodiment of the invention component drawings (annular overflow trough)
Fig. 2 splash board type overflow mechanism is " M-N " section zoomed-in view among Fig. 1.
(5) specific embodiment
In the embodiment in figure 1, annular overflow trough can be the splash board type overflow mechanism monomer manufacturing of Fig. 2 by section, constitutes the monoblock type overflow launder, also can be combined by several sections splash board type overflow mechanism pieces, constitutes the segmented overflow launder.The splash board type overflow mechanism that the present invention relates to mainly spatters plate portion 1 by hydrojet, and barrel part 2 and cylindrical shell 3 are formed.Wherein hydrojet is spattered plate portion 1 and barrel part 2 can adopt integral body or combining structure.Its basic functional principle is: supply water (or feed flow) under pressure, h enters spill cavity by the feed flow hole, is injected in hydrojet and spatters on the plate portion 1, and jet spatters between plate portion 1 and the barrel 2 repeatedly backwash through hydrojet, evenly overflow by liquid outlet f then, fall the formation liquid film along cylindrical shell 3 inwalls.
