Description
Technical field
The present invention relates to the liquid distribution device in a kind of Falling Film Evaporator of Horizontal Tube equipment, specifically relating to a kind of for making uniform liquid be distributed in current-sharing ramp type liquid distribution trough on horizontal heat exchange tube.
Background technology
It is high that Falling Film Evaporator of Horizontal Tube has heat transfer efficiency; Have a narrow range of temperature, be specially adapted to thermosensitive solution evaporation; Equipment is simple, and volume is little; After startup, do not need live steam; Power consumption is low, low cost and other advantages, is widely used in now the industries such as food, medicine, chemical industry, sewage disposal, desalinization.One of key equipment of Falling Film Evaporator of Horizontal Tube is liquid distribution trough (i.e. liquid distributor), and solution, through liquid distribution trough, is evenly distributed on horizontal heat exchange tube, forms the liquid film of thin layer, by heating evaporation.Falling Film Evaporator of Horizontal Tube heat exchange efficiency is high, and key is just that liquid distribution trough can make solution be uniformly distributed on each horizontal tube length direction, and forms uniform liquid film in horizontal tube circumference.The uniformity of solution distribution and the quality of film forming are the standards of a judgement liquid distribution trough performance quality.
At present, widely used liquid distribution trough mainly contains tubular type, board-like, slotted disc type, fountain etc.Various liquid liquid distributor respectively has pluses and minuses.Tubular type liquid distributor structure is simple, but anti-stifled ability, easily cause obstruction, make liquid film skewness; Board-like liquid distributor, flow rate of liquid is fast, and cloth liquid point is uneven, affects cloth liquid effect; Slotted disc type liquid distributor, Treatment Solution amount is large, and anti-stifled ability is strong, but easily occurs bias current and sheet stream, affects cloth liquid uniformity; Fountain liquid distributor, spray face is circular, sprinkler spacing and highly bad grasp, easily causes sprinkling uneven.
Summary of the invention
In order to prior art Problems existing, the object of the invention is to provide a kind of current-sharing ramp type liquid distribution trough, it has the advantages such as structure is simple, easy to process, operating flexibility is large, usability is wide, cloth liquid point is many, liquid distribution is even.
The technical solution adopted for the present invention to solve the technical problems is a kind of current-sharing ramp type liquid distribution trough, comprising: flange, feed pipe, horizontal branch pipe, taper liquid distributor, liquid distribute flute profile shape plate, connecting rod and cloth liquid tooth again; Described flange is arranged at porch; Described feed pipe one end and Flange joint, the other end is connected with horizontal branch pipe; Described horizontal branch pipe is connected with multiple taper liquid distributor; Equally spaced spray apertures is had below each taper liquid distributor; The described liquid castellated plates that distributes again is arranged on below taper liquid distributor, the liquid castellated plates that distributes again equidistantly fixes both sides by connecting rod, liquid distributes between castellated plates and connecting rod place horizontal plane again and has angle, each liquid castellated plates that distributes again is rotated in angular range, according to spacing and the highly decision of heat exchanger tube during specific works, such as when heat exchanger tube spacing is large or highly large time, distribute the again angle of inclination of castellated plates of liquid becomes large; On the contrary, angle of inclination diminishes.Each liquid distributes castellated plates again along spacing between slidable adjustment plate on connecting rod, and rotates on connecting rod and regulate angle of inclination; Described liquid distributes castellated plates again, and every block castellated plates lower end is provided with cloth liquid tooth, and it is protruding that castellated plates upper surface is provided with some dihedrals.
Described taper liquid distributor is set in parallel on horizontal branch pipe, and taper liquid distributor center line is vertical with horizontal branch pipe center line horizontal direction.
Described taper liquid distributor tapering is 1:10 ~ 1:20.
Described angle is 10 ° ~ 80 °.
The invention has the beneficial effects as follows, after solution enters conical liquid distributor pipe, although there is drag losses, but due to the effect of conical pipe, the flow velocity of solution does not lose, and maintains certain flow velocity, be evenly distributed after spray apertures flows out, meanwhile, the phenomenon of managing interior hydrops blocking spray apertures can also be prevented; The liquid castellated plates that distributes again is fixed by connecting rod, and can slide on connecting rod and rotate, conveniently can be applicable to the evaporimeter of different tube pitch, easy to operate, elastic space be large; Because the liquid castellated plates that distributes again has certain gradient, there is a fixed gap between plate and plate, water conservancy diversion circulation effect is played to steam, reduces the disturbance to cloth liquid drop; The liquid castellated plates plate face that distributes again is provided with dihedral projection, having rectification to divide equally effect, reducing solution flow rate simultaneously, solution is evenly distributed onboard dripping the solution poured on plate; Be provided with cloth liquid tooth in the liquid castellated plates bottom that distributes again, solution divides uniformly liquid distribution point through cloth liquid tooth, and dissolution homogeneity is distributed on the horizontal heat exchange tube of lower end.

Fig. 2 is taper liquid distributor top view;
Fig. 3 is that liquid distributes profile of tooth plate structure figure again;
In figure 1, flange, 2, feed pipe, 3, horizontal branch pipe, 4, taper liquid distributor, 5, liquid distributes flute profile shape plate again, 6, connecting rod, 7, cloth liquid tooth, 8, spray apertures, 9, dihedral is protruding.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is described in detail.
As Fig. 1, flange 1 is arranged at porch, solution is by feed pipe 2, enter horizontal branch pipe 3, horizontal branch pipe 3 is connected with multiple taper liquid distributor 4, and taper liquid distributor 4 is set in parallel on horizontal branch pipe 3, taper liquid distributor 4 center line is vertical with horizontal branch pipe 3 center line horizontal direction, the length of horizontal branch pipe 3 and taper liquid distributor 4 and number determine according to the length of heat exchanger tube in evaporimeter and number, the tapering of taper liquid distributor 4 at 1:10 ~ 1:20, according to concrete Operating condition adjustment; Spray apertures 8 is evenly distributed on taper liquid distributor 4 lower central line, and the diameter of spray apertures 8 can not be greater than the diameter of conical pipe the narrowest end place pipe, the number of spray apertures 8 according to taper liquid distributor 4 number and length determine.Solution is evenly sprayed by spray apertures 8 and distributes in castellated plates 5 again to liquid; The liquid castellated plates 5 that distributes again is fixed by connecting rod 6, and the liquid castellated plates 5 that distributes again is slided on connecting rod 6 simultaneously, and liquid distributes again, castellated plates 5 can be rotated on connecting rod 6; Slided on connecting rod and rotate rearrange liquids to be distributed profile of tooth distance between plates and angle of inclination again by the liquid castellated plates that distributes again, the cloth liquid tooth that liquid is distributed below castellated plates again aims at heat exchanger tube center; Spray the liquid that distributes again in castellated plates to liquid liquid distribute again the up and parallel staggered dihedral projection 9 of row of castellated plates effect under be rectified and divide equally, reduce flow velocity simultaneously, flowing uniformly to liquid distributes on the cloth liquid tooth 7 of castellated plates bottom again, is evenly distributed on each root heat exchanger tube through cloth liquid tooth 7.
