Description
Technical field
The utility model relates to refine oil, petrochemical industry, chemical industry, light industry, pharmacy, environmental protection, the gas-liquid distribution in the industry such as atomic energy
Device is widely used under normal pressure, decompression, pressurized conditions in the packed tower of the processes such as rectifying, absorption, desorption, washing.
Background technique
Liquid distribution trough device is the most important tower internals of packed tower, and operating flexibility determines the operating flexibility of packed bed.
Liquid distribution trough device is located at the upper end of filler, and phegma and liquid phase feeding are evenly distributed on the surface of filler by it, is formed
Liquid initialization distribution.And initial distribution needs to realize by liquid distribution trough, therefore, the design of liquid distribution trough is particularly important.
Good liquid distribution trough should have following features: liquid distribution is uniformly, the free cross-section that passes through of gas phase is big, resistance
Small, operating flexibility is big, is not easy to block, does not easily cause entrainment and foam.
Currently, common liquid distribution trough by structure type can be divided into tank type liquid distributor, tubular liquid in packed tower
Body distributor, injecting type liquid distribution trough, disc type liquid distribution trough.And tank type liquid distributor be common liquid distribution trough it
One, it is assembled by each unit component, can be distributed to packing layer by aperture with aperture, liquid in trench bottom or side wall
On.
The tank type liquid distributor of the prior art generally by several first-stage tanks and multiple second-level grooves above and below vertically fold fall and
At liquid phase is introduced into first-stage tank from top to bottom, is then prorated in second-level groove by first-stage tank, and liquid passes through in second-level groove
Aperture is evenly distributed on packing layer, although second-level groove distribution effects is pretty good, the distribution of first-stage tank is the aperture on its slot
It is assigned in the second-level groove of varying length, is difficult evenly distributed with hole count.If distribution unevenness easily causes local filler liquid measure excessive,
It is short-circuit to make phase, or even causes the dry plate phenomenon of certain side filler, declines separative efficiency sharply.And influence liquid distribution not
Equal most serious factor is that liquid distribution trough irrational mix designs and installation level is unbalance.
The tank type liquid distributor of the prior art has the characteristics that big flow, antiblocking and distribution performance are stable, is suitable for
Large stuffing tower.But structure is complicated, the liquid level of each branch slot be difficult to control it is completely the same, levelness is unbalance easily lead to drip heat transfer with
Mass transfer effect is not good enough.

The interior liquid that cannot be flowed out in time from bottom opening then enters major trough from lateral opening hole outflow, to improve the operation of steady liquid bath
Elasticity.
Tank type liquid distributor compared to the prior art, the utility model tank type liquid distributor have the advantage that
It is welded with equally distributed round steel in steady liquid bath above 1 major trough, is tiled different model on round steel according to processing performance
Silk screen, on the one hand on the other hand can stablize the liquid fluctuating in lautertuns with filtering solid particles and impurity.
The bottom and two sides of 2 steady liquid baths are evenly equipped with uniform circular hole, and the area and major trough distribution hole of bottom opening press technique
Desired ratio opens system.By improving liquid level when steady liquid bath minimum liquid level, make the liquid flow of steady liquid bath bottom distribution hole
Amount is evenly distributed, so that the stable purpose of major trough liquid level is played, so that the liquid distribution of tank type liquid distributor is more uniform.Surely
The purpose of liquid bath lateral opening hole be when the operation of high liquid measure, the liquid that cannot be flowed out in time from bottom opening in steady liquid bath then from
Lateral opening hole outflow enters major trough, to improve the operating flexibility of steady liquid bath.Major trough bottom is equally uniformly provided with a certain number of
Circular hole, liquid is finally evenly and smoothly distributed in each slot via the distribution hole of major trough in steady liquid bath.
3 slot groove bodies are in the groove-like for having constant slope, and equidistant spray apertures are opened on inclined groove body, can be according to technique
It is required that the twocouese spacing of adjustment spray apertures, the adjustable range of twocouese for spraying pitch of holes is 50mm ~ 120mm.Compared to
The arrangement of the tank type liquid distributor of the prior art, spray apertures is more uniform and more, and spray spacing also reaches unanimity.It is recessed
The branch slot groove body of channel-shaped will not make solid impurity in liquid hoard to block spray apertures, be connected in branch slot groove body two sides
Branch slot liquid barrier, liquid is uniformly fallen by inclined spray apertures along liquid barrier in branch slot groove body, divides liquid uniformly
Cloth is in filler upper surface.
