Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
As shown in Fig. 1-Fig. 7, a kind of high performance tank type liquid distributor, comprise pre-distributor pipe, first-stage tank 3, second-level groove 4, first-stage tank 3 is arranged on the lower end of pre-distributor pipe, and second-level groove 4 is arranged on the lower end of first-stage tank 3; Described pre-distributor pipe comprises the main feed pipe 1 of pre-distribution, pre-distributor pipe arm 2, and the main feed pipe of described pre-distribution 1 connects the pre-distributor pipe arm 2 of more than two or two downwards, and the short tube 6 in pre-distribution arms 2 stretches in the overflow launder 9 of first-stage tank 3; Described first-stage tank 3 is arranged on the below of pre-distributor pipe arm 2, and the bottom opening of first-stage tank 3 is provided with overflow launder 9 in the inside of first-stage tank 3; Be interconnected between described second-level groove 4, the bottom board symmetry of second-level groove 4 offers liquid distribution hole.
During work, liquid enters from the main feed pipe 1 of pre-distribution, be drained into the overflow launder 9 of first-stage tank 3 from pre-distributor pipe arm 2, overflow to first-stage tank 3 from overflow launder 9 again, then flow into second-level groove corresponding to lower end 4 from the bottom opening of first-stage tank 3, finally evenly flow out from the liquid distribution hole of second-level groove 4 base plate.
See Fig. 2-Fig. 3, aperture 5 is offered at the top of described pre-distributor pipe arm 2, liquid can be directly observed whether to be full of by aperture 5, simultaneously can emptying inner air tube by aperture 5, at the liquid outlet of the bottom of pre-distributor pipe arm 2, short tube 6 is installed, welds adjustable area annulus 7 in short tube 6 exit.
Be processed with a through hole in the centre of described adjustable area annulus 7, the surrounding of through hole is provided with tapped through hole 13.By screwing bolt on tapped through hole 13, regulate the liquid outlet quantity of fluid pressure in pre-distributor pipe and short tube 6.
Short tube 6 is stretched in first-stage tank 3 overflow launder 9, be used for stable liquid go out stream, by regulating the size of adjustable area annulus 7 discharge area, the liquid outlet quantity of the fluid pressure in adjustable pipe and short tube 6, when pre-distributor pipe arm 2 top aperture 5 sprays the liquid of certain altitude, prove that its inside is filled with liquid.
The diameter of the intermediate throughholes of adjustable area annulus 7 is comparatively large, and the diameter of surrounding tapped through hole 13 is less, and adjustable area annulus 7 screws the bolt of varying number, can the discharge area of annulus.
See Fig. 4-Fig. 6, described overflow launder 9 comprises base plate 11, sieve plate 8, overflow launder weir 12, and overflow launder weir 12 is fixed on the both sides of base plate 11, forms overflow launder 9, described overflow launder weir 9 is flat weir or profile of tooth weir, and sieve plate 8 is arranged in overflow launder 9, higher than the position of base plate 11.Described sieve plate 8 is evenly equipped with through hole, and the both sides of sieve plate 8 are fixed on overflow launder weir 12, and the distance between sieve plate 8 and base plate is 1cm-2cm.
The installation site of sieve plate 8, immediately below pre-distributor pipe arm short tube 6, effectively can prevent liquid splash and first-stage tank 3 outlet at bottom liquid Biased flow phenomenon in first-stage tank 3.
See Fig. 7-Fig. 8, second-level groove 4 is with bolts, and is all communicated with between any two, and make liquid level in each second-level groove 4 consistent, steady, the uniform liquid of distribution is stablized, and second-level groove 4 bottom opening can be comparatively large, prevent liquid from blocking.The mid portion of two second-level groove 4 connections is gas phase channel 10, and aisle spare is comparatively large, and gas phase drag is little.
Tank type liquid distributor dispatch from the factory last as need to do distributing homogeneity test.During test, liquid enters in pre-distributor pipe arm 2 from the main feed pipe of pre-distributor pipe 1, flow in corresponding first-stage tank 3 from the short tube 6 of each arm again, if find each arm short tube 6 mass flow discrepancy during test, by regulating the discharge area of the adjustable area annulus 7 in short tube 6 end, a certain number of bolt of namely screwing on controls, when pre-distributor pipe arm 2 top aperture 5 sprays certain altitude fluid column, illustrate in pre-distributor pipe and be full of liquid, now the rate of discharge of each short tube 6 is even.This method of adjustment is simple, and determination methods is directly perceived, can also realize the uniform pore openings of each short tube 6 outlet or uneven perforate.First the liquid entering first-stage tank 3 prevent liquid splash through sieve plate 8, then flow in overflow launder 9, entered in first-stage tank 3, make liquid level stabilizing in first-stage tank 3 by overflow launder 9 overflow, and outlet is without Biased flow phenomenon.Enter second-level groove 4 from first-stage tank 3 outlet at bottom liquid out to distribute, be interconnected between second-level groove 4, so liquid level is substantially identical in each groove, the uniform liquid of second-level groove 4 small hole at bottom part distribution is stablized.In tower, gas phase is upwards flowed by the gas phase channel 10 between second-level groove 4, and resistance is little, and pressure drop is low.
