Description
Technical Field
The utility model relates to a novel high-efficient liquid subsection field specifically is a pinhole feed liquor groove tubular liquid distributor, can be in the plane evenly distributed liquid.
Background
Existing channel liquid distributors are typically slotted into the side of the downcomer through which the liquid flows into the downcomer, with the downcomer outlet distributing the liquid. In practical engineering application, the liquid in the liquid dividing tank has high flow rate, obvious liquid level fluctuation along the liquid flowing direction, and different liquid levels of liquid flowing into the downcomer, so that the liquid flow difference in the downcomer is obvious, and although the liquid outlets are uniformly arranged in a plane, the flow on each liquid outlet is different, so that the liquid is not uniformly distributed, and the use effect of the liquid distributor is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a little hole feed liquor groove tubular liquid distributor to the technical problem that above-mentioned exists.
The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a micropore feed liquor groove tubular liquid distributor, this distributor includes the liquid supply main pipe, divides the liquid pipe, divides cistern and downcomer, divide the liquid pipe to connect out from the liquid supply main pipe, divide the liquid pipe export to place in dividing the liquid groove, divide the week side in cistern to have arranged the downcomer, the one end of downcomer is fixed in dividing the cistern, the other end arranges to go out the liquid outlet hole.
The utility model discloses among the technical scheme: the down-flow spout in the liquid dividing groove is provided with a liquid inlet hole.
In some preferred embodiments: the top end or the side wall of the downcomer positioned in the liquid dividing groove is provided with a liquid inlet hole.
The utility model has the advantages that:
the existing trough pipe type liquid distributor is usually provided with a groove on the side surface of the downcomer, the height from the liquid surface to the bottom of the downcomer is h, and as shown in fig. 2, according to the hydrostatic principle, the flow rate in the downcomer is in direct proportion to the 3/2 th power of h. Adopt the technical scheme of the utility model the aperture is opened to the downcomer side, and the liquid level is h to the height in the aperture, as shown in fig. 3, according to the hydrostatic principle, the flow in the downcomer is directly proportional with the 1/2 power of h. When the liquid level in the liquid dividing tank fluctuates, the flow in each downcomer in the prior art changes obviously, and the flow of each liquid outlet point in the liquid distribution plane is uneven. When adopting the technical scheme of the utility model, the liquid level fluctuation is little to the liquid flow change influence in getting into each downcomer, and liquid distribution is even on each play liquid point.

Detailed Description
The present invention will be further explained with reference to the following embodiments, but the scope of the present invention is not limited thereto:
referring to fig. 1, 4 and 5, a small-hole liquid inlet groove pipe type liquid distributor comprises a liquid supply main pipe (1), a liquid distribution pipe (2), a liquid distribution groove (3) and a downcomer (4), wherein the liquid distribution pipe (2) is connected out from the liquid supply main pipe (1), the outlet of the liquid distribution pipe (2) is arranged in the liquid distribution groove (3), the downcomer (4) is arranged on the peripheral side of the liquid distribution groove (3), one end of the downcomer (4) is fixed in the liquid distribution groove (3), and the other end of the downcomer is arranged in a liquid outlet hole. The side surface or the top end of the downcomer (4) positioned in the liquid dividing groove (3) is provided with a liquid inlet hole.
Referring to fig. 4, the present invention provides a solution, in which the liquid distributor comprises a main liquid supply pipe 1, a liquid distribution pipe 2, a liquid distribution tank 3 and a downcomer 4.
The inlet of the liquid supply main pipe 1 is connected with an external liquid inlet pipeline, liquid enters the liquid supply main pipe 1 and then enters the acid separation tank 3 through the liquid separation pipe 2, the liquid level of the liquid separation tank 3 is formed in the liquid separation tank due to liquid flowing resistance, the small hole in the top end or the side wall of the downcomer 4 is immersed below the liquid level of the liquid separation tank 3, and the liquid enters the downcomer 4 through the small hole and flows to each liquid outlet in a plane. Liquid gets into and divides the liquid tank flow rate very fast, and the inslot liquid level is obvious undulant, and the peak value is 70mm for 80mm valley value like liquid level height h (see fig. 3), adopts the utility model discloses technical scheme's liquid distributor, in valley value liquid level precipitation intraductal flow only than about 6.5% less than the flow in peak value liquid level precipitation intraductal, liquid outlet liquid flow difference is little, and liquid distribution is. And the prior art scheme of slotting the side surface is adopted, the flow in the downcomer of the valley liquid level is only about 30 percent less than that in the downcomer of the peak liquid level, the liquid flow difference of the liquid outlet is large, and the liquid is distributed unevenly.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
