Description
Technical field
What the present invention relates to is a kind of liquid distributor of desulfuration absorbing tower, especially relates to a kind of tube and tank type liquid distributor, belongs in packed tower and establish liquid distribution technical field.
Background technology
Packed tower is the mass transfer apparatus using the filler in tower as gas-liquid two-phase Contact component.The tower body of packed tower is vertical cylinder always, and supporting plate is equipped with in bottom, and filler is to huddle or the mode of whole block is placed on support plate.Hold-down grid is installed, in case blown by ascending air in the top of filler.It is large that packed tower has production capacity, the advantages such as separative efficiency is high, and pressure drop is little, and liquid holdup is little, and operating flexibility is large.
Liquid distribution trough is an important packed tower internals, uniform liquid can be distributed in packing layer top, effectively reduces the enlarge-effect caused by the bad distribution of liquid, thus gives full play to the efficiency of filler.The quality of liquid initial distribution not only affects the mass-transfer efficiency of filler, but also can have an impact to the operating flexibility of filler.
Pipe groove type liquid distributor is the new-type liquid distribution trough of one popular in recent years, combines the advantage of pipe distributor and groove type distributor, effectively can reduce the wall effect of tower, supernatant liquid is evenly distributed for the first time, thus improves gas-liquid mass transfer efficiency.But the feed liquid distribution between feed pipe and first-stage tank is extremely important to the cloth liquid effect of whole distributor, and a lot of distributor arranges downflow weir in first-stage tank, in order to make exactly, liquid is more steady, distribution is more even.
In recent years, a lot of Pipe groove type liquid distributor improves being uniformly distributed of liquid all to a certain extent, but such as do not consider that second-level groove differs in length, first-stage tank liquid distributing hole does not have enough distribution densities, and in feed pipe, feed liquid directly enters the development that the first-stage tank series of problems that makes first-stage tank liquid distribution uneven etc. still annoyings Pipe groove type liquid distributor.
Summary of the invention
In order to give full play to the effect of the stable and uniform distributes liquid of first-stage tank in Pipe groove type liquid distributor, improve the liquid distribution effect of whole distributor, promote the industrial applications of Pipe groove type liquid distributor, the present invention proposes a kind of liquid distributor of desulfuration absorbing tower.This distributor, by arranging liquid distributing hole between striker plate and between first order groove and second level groove, solves the technical problem that liquid mobile equilibrium distributes.
The scheme that technical solution problem of the present invention adopts is:
Feed pipe is communicated with catheter, separating tube is connected with in catheter bottom, separating tube both sides are respectively equipped with liquid barrier, liquid barrier is arranged in first order groove, second level groove is provided with in first order groove bottom, multiple second level groove is that subcircular is spaced, and is being connected between the groove of the second level by communicating pipe, is respectively equipped with liquid distributing hole in liquid barrier bottom and the first order groove territory section on groove top, the second level and the bottom of second level groove.
Two liquid barrier bottoms are cloth liquid zone, and top is overflow area, forms transition region between overflow area and cloth liquid zone.
The liquid stream that the liquid stream flowed out from liquid barrier and overflow area are overflowed flows in the groove of the second level jointly from the cloth liquid zone of the first collection groove.
Good effect, uneven liquid can be carried out equilibrium assignmen by liquid distributor of the present invention, and have liquid flow assignment effective, efficiency is high, the simple feature of structure.Be suitable for applying as liquid distributor at chemical field.

Detailed description of the invention
According to the figure, feed pipe 1 is communicated with catheter 2, separating tube 3 is connected with in catheter bottom, separating tube both sides are respectively equipped with liquid barrier 4, liquid barrier is arranged in first order groove 5, is provided with second level groove 6 in first order groove bottom, and multiple second level groove is that subcircular is spaced, connected by communicating pipe 7 between the groove of the second level, be respectively equipped with liquid distributing hole in liquid barrier bottom and the first order groove territory section on groove top, the second level and the bottom of second level groove.
Two liquid barrier bottoms are cloth liquid zone, and top is overflow area, forms transition region between overflow area and cloth liquid zone.
The liquid stream that the liquid stream flowed out from liquid barrier and overflow area are overflowed flows in the groove of the second level jointly from the cloth liquid zone of the first collection groove.
The course of work of the present invention and feature:
Feed liquid flows through catheter from feed pipe, flow down from separating tube, be injected into the cloth liquid zone between liquid barrier, part liquid stream flow into the cloth liquid zone of first order groove from the bottom liquid distributing hole of liquid barrier, the liquid stream exceeding liquid barrier suitable for reading forms overflow in overflow area, oppositely flow into the cloth liquid zone of first order groove, flow in the groove of the second level via liquid distributing hole set on the groove of the second level, then flow out from the liquid distributing hole set by groove bottom, the second level, form equally distributed liquid stream.
The effect of overflow area is the effect playing lower drainage stream buffering;
The effect of liquid barrier stops liquid stream turbulent flow, cuts down unbalanced pressure, liquid stream is evenly flowed out from the liquid distributing hole of liquid barrier;
The liquid distributing hole set by first order groove liquid distributing hole section on groove top, the second level, makes liquid stream flow to second level groove;
The effect of communicating pipe is communicated with liquid level between the groove of each second level at sustained height, and keep pressure balance.
Embodiment 1
Running environment: absorption tower tower diameter 1.2m, sulfur-bearing gas charging 3300m/h, absorbing liquid inlet amount 8t/h, MDEA mass fraction 30%.Absorption tower adopts three sections of 3 meters of structured packing structured packings, feeding temperature 20-25 DEG C, sulfide hydrogen 5000ppm in gas.Structure of distributor is before simple, and do not have first-stage tank and flow-stopping plate, cause absorbing liquid skewness, desulfurized effect does not reach industrial requirements always, causes absorbing liquid use amount higher, and hear rate and regeneration energy consumption remain high.Use this liquid distribution trough, hydrogen sulfide content in the gas after purification can be made to control within 10ppm, and absorbent consumption and energy consumption are obtained for and effectively control.
Embodiment 2
Running environment: absorption tower tower diameter 2m, sulfur-containing smoke gas charging 5000m/h, absorbing liquid inlet amount 10t/h, MDEA mass fraction 30%.Absorption tower adopts two sections of 4 meters of structured packings, feeding temperature 20-25 DEG C, containing sulfur dioxide 3000ppm in flue gas.Structure of distributor is before simple, does not have first-stage tank and flow-stopping plate, causes absorbing liquid skewness, desulfurized effect does not reach industrial requirements always, causes absorbing liquid use amount higher, and hear rate and regeneration energy consumption remain high, can not give full play to tower body efficiency, treating capacity is on the low side.Use liquid distribution trough of the present invention, the sulfur dioxide in flue gas content after purification can be made to control within 20ppm, and absorbent consumption and energy consumption are obtained for and effectively control, and improve treatment quantity.
