The rectifying tower is the essential separation and purification equipment of chemical industry, and in the rectifying tower rectification process, after the material enters the tower, must be with feeding evenly, just can reach better mass transfer heat transfer process effect, carry out subsequent separation and purification work. Therefore, the liquid distribution disc is needed to uniformly distribute the liquid to the materials so as to ensure the effect of the subsequent process. If need carry out the rectification purification to the product many times in trichloroethylene's production, and the rectifying column is important separation and purification equipment, in order to guarantee the purification effect, need set up cloth liquid dish in the rectifying column and carry out even cloth liquid to the material to guarantee the separation and purification effect of follow-up process.
In actual production, the liquid distribution disc is often subjected to uneven impact of materials to one side of the liquid distribution disc due to changes of factors such as feeding amount and pressure during feeding, so that the liquid distribution disc is inclined and eroded, and the single-side impact on the liquid distribution disc is increased along with the increase of flow and pressure. The inclination of the liquid distribution disc can lead the materials not to uniformly enter the rectifying tower, thus leading the effect of the mass and heat transfer process of the materials in the rectifying tower to be reduced, causing the conditions that the low-boiling-point substances of the rectified and extracted products exceed the standard, the purity does not reach the standard and the like, affecting the product quality, even affecting the yield, the normal production and the like. Meanwhile, the efficiency and the service life of the liquid distribution plate and the filler can be greatly reduced because the material impacts one side of the liquid distribution plate and the filler for a long time, however, most of the rectifying towers are produced continuously for a long time, and the problem that the liquid distribution plate is damaged is difficult to find and treat in time in production. Therefore, the separation and purification effect of the rectifying tower is improved by eliminating the inclination of the liquid distribution disc and prolonging the service life of the liquid distribution disc, and the problem to be solved at present is urgently solved.

The utility model provides a technical scheme that its technical problem adopted is: a liquid distribution device of a rectifying tower comprises a liquid distribution disc and a feed pipe, wherein the feed pipe is bent downwards after entering the rectifying tower and is vertically downwards, and an outlet of the feed pipe is opposite to the central position of the liquid distribution disc; a pre-liquid distributor is arranged at the outlet of the feeding pipe, the pre-liquid distributor is in an inverted funnel shape, one end of the pre-liquid distributor is connected with the outlet of the feeding pipe, and the other end of the pre-liquid distributor is provided with a cover plate with an opening; the diameter of the cover plate is 60% -80% of the diameter of the liquid distribution plate.
Further, the opening on the cover plate is positioned on the circumference of 70% of the diameter of the cover plate.
Further, the number of the openings is 8, and the openings are arranged at equal intervals.
Further, the diameter of the opening is 1/2 of the pipe diameter of the feeding pipe.
Further, the openings in the cover plate include an inner opening at a circumference of 40% of the diameter of the cover plate and an outer opening at a circumference of 75% of the diameter of the cover plate.
Further, the number of the openings of the inner hole is 6 which are equidistantly arranged, and the number of the openings of the outer hole is 8 which are equidistantly arranged.
Further, the diameter of the inner hole is 1/4 of the pipe diameter of the feeding pipe, and the diameter of the outer hole is 1/2 of the pipe diameter of the feeding pipe.
Furthermore, the cross sections of the cover plate and the liquid distribution disc are circular, and the center lines of the cover plate and the liquid distribution disc are collinear.
The inventor researches and finds that the diameter of the cover plate is 60-80% of the diameter of the liquid distribution plate, holes are formed in the circumference of 70% of the diameter of the cover plate, or inner holes are formed in the circumference of 40% of the diameter of the cover plate and outer holes are formed in the circumference of 75% of the diameter of the cover plate, so that when pressure or feeding quantity is greatly changed, the material entering the liquid distribution plate is uniform and stable, if the holes are few, the feeding quantity of a rectifying tower cannot be met, if the holes are too many, the flow of the material outside the liquid distribution plate is suddenly reduced, and the outer side filler cannot play a role; 8 trompils are arranged to the equidistance on the circumference of 70% apron diameter, or the trompil quantity of hole is 6 that the equidistance was arranged, 8 that the trompil quantity of outer hole was arranged for the equidistance, and the trompil has both guaranteed the feed rate as the passageway of material flow direction cloth liquid dish, has satisfied the even entering cloth liquid dish of material simultaneously.
The diameter of the opening is 1/2 of the pipe diameter of the feeding pipe, or the diameter of the inner hole is 1/4 of the pipe diameter of the feeding pipe, and the diameter of the outer hole is 1/2 of the pipe diameter of the feeding pipe, so that the feeding quantity of the liquid into the rectifying tower after the liquid pre-distributor is added can be ensured not to change.
The utility model has the advantages that: the utility model adopts the elbow feeding, the material enters the liquid distribution disc after the liquid pre-distribution device pre-distributes liquid, so that the material uniformly and stably enters the rectifying tower, and the separation and purification effect of the rectifying tower is improved; and when the pressure or the feeding amount is greatly changed, the materials can be ensured to uniformly enter the rectifying tower, the liquid distribution plate cannot be inclined and eroded, and the service life of the liquid distribution plate is prolonged.
