Example 1:
the embodiment provides a disc type liquid distributor, which is used for solving the technical problem that the disc type liquid distributor in the related art is poor in using effect. Specifically, the disc-type liquid distributor in the related art is only provided with one liquid distribution plate, and liquid drops on the liquid distribution plate and then flows to the working area through the fine holes arranged on the liquid distribution plate.
The disc-type liquid distributor provided by this embodiment guides the liquid to the middle space 42, after the liquid level in the middle space 42 is stable and the liquid therein reaches a certain amount, the liquid in the middle space 42 permeates into the upper space 41, and with the help of the first flow guide pipes 5 which are uniformly distributed, the liquid in the upper space 41 is guided into the lower space 43, so that the liquid can be distributed everywhere in the lower space 43.
Specifically, the disc liquid distributor that this embodiment provided includes first board 1, second board 2, feed liquor pipe 3 and first honeycomb duct 5, wherein:
the first plate 1 and the second plate 2 are both flat plates, the first plate 1 and the second plate 2 are both fixed on the inner wall of the container 4, and the first plate 1 and the second plate 2 divide the inner space of the container 4 into an upper space 41, a middle space 42 and a lower space 43, the first plate 1 is located above the second plate 2, specifically, the upper space 41 is the inner space of the container 4 above the first plate 1, the lower space 43 is the inner space of the container 4 below the second plate 2, and the middle space 42 is an interlayer between the first plate 1 and the second plate 2. It should be noted that, since the first plate 1 and the second plate 2 are both fixed to the inner wall of the container 4, the middle space 42 is a closed space. And the first plate 1 and the second plate 2 are arranged in parallel, so that the heights of the middle layer space 42 are the same, as an optional implementation manner of this embodiment, the height value range of the middle layer space 42 in this embodiment is 300mm-500 mm. A plurality of first through holes 11 are formed in the first plate 1, and the first through holes 11 are evenly distributed in the first plate 1. Of course, the first plate 1 and the second plate 2 may also be a bent plate or an arc-shaped plate, and the first plate 1 and the second plate 2 may also be arranged non-parallel, but it is necessary to ensure that the upper surface of the first plate 1 is a plane.
The liquid inlet pipe 3 is connected on the first plate 1, and this liquid inlet pipe 3 communicates with above-mentioned middle level space 42, like this, liquid inlet pipe 3 alright with leading-in above-mentioned middle level space 42 of liquid, with the help of the mobility of liquid, a period of time after, the liquid level in middle level space 42 will tend to stable, the last face that also is the second board 2 will be covered with to liquid, the volume of liquid in middle level space 42 accumulates to certain degree, liquid in middle level space 42 will permeate into upper space 41 through above-mentioned first through-hole 11, because the quantity of first through-hole 11 is a plurality of, evenly distributed is gone up on first board 1 to a plurality of first through-hole 11, like this, then, each position homoenergetic on can guaranteeing first board 1 has permeated liquid.
