Abstract
The invention discloses a small-hole liquid inlet groove pipe type liquid distributor, and belongs to the field of novel efficient liquid distribution. The device comprises a main liquid supply pipe, a liquid dividing groove and a downcomer, wherein the liquid dividing pipe is connected out from the main liquid supply pipe, an outlet of the liquid dividing pipe is placed in the liquid dividing groove, the downcomer is arranged on the peripheral side of the liquid dividing groove, one end of the downcomer is fixed in the liquid dividing groove, and the other end of the downcomer is a liquid outlet hole. By adopting the technical scheme of the invention, the influence of liquid level fluctuation on the change of liquid flow entering each downcomer is small, and the liquid on each liquid outlet is uniformly distributed.
Description
Technical Field
The invention relates to the field of novel efficient liquid distribution, in particular to a small-hole liquid inlet groove pipe type liquid distributor which can uniformly distribute liquid in a plane.
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.
Disclosure of Invention
The invention provides a small-hole liquid inlet groove pipe type liquid distributor aiming at the existing technical problems.
The purpose of the invention 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 technical scheme of the invention is as follows: 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 invention has the beneficial effects 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. By adopting the technical scheme of the invention, the side surface of the downcomer is provided with the small hole, the height from the liquid surface to the small hole is h, and as shown in figure 3, according to the hydrostatic principle, the flow in the downcomer is in direct proportion to the 1/2 th 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 the technical scheme of the invention is adopted, the influence of liquid level fluctuation on the change of liquid flow entering each downcomer is small, and the liquid is uniformly distributed on each liquid outlet point.

Detailed Description
The invention is further illustrated by the following examples, without limiting the scope of the invention:
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, the liquid distributor is composed of a main liquid supply pipe 1, a liquid dividing pipe 2, a liquid dividing groove 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. The liquid enters the liquid separating groove at a high flow rate, the liquid level in the groove obviously fluctuates, if the peak value of the liquid level height h (see figure 3) is 80mm, and the valley value is 70mm, the flow in the valley liquid level downcomer is only about 6.5 percent less than the flow in the peak liquid level downcomer by adopting the liquid distributor adopting the technical scheme of the invention, the liquid flow difference of the liquid outlet is small, and the liquid distribution is uniform. 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.
