Description
Technical field
The utility model relates to a kind of liquid distribution trough, is specifically related to the branched cast liquid distribution trough of a kind of network structure, is applied in packed tower.
Background technology
In current oil, chemical engineering industry, packed tower obtains with features such as its high efficiency, low pressure drop, large flux and applies more and more widely.In packed tower gas-liquid two-phase fluid on tower section to be uniformly distributed with fully contacting be the necessary condition ensureing efficient mass transfer in packed tower.Along with novel, High Efficient Standard Packing exploitation and increasingly extensive to apply, the demand researching and developing novel, efficient tower internals (particularly gas, liquid distribution trough) is also more and more urgent.Liquid distribution trough is most important tower internals, and the liquid distribution trough with well distributed performance can provide uniform liquid initial to distribute, and weakens the harmful effect of enlarge-effect and end effect, can improve the separative efficiency of packed tower further.
Traditional liquid distribution trough comprises nozzle-type liquid distribution trough, calandria liquid distributors, disc type and tank type liquid distributor.Often kind of traditional liquid distribution trough all has self intrinsic defect, and such as, plain nozzle formula liquid distribution trough can not form being uniformly distributed of liquid in major diameter packed tower; Disc type liquid distribution trough easily causes entrainment; Current, although the Application comparison of tank type liquid distributor is extensive, it is not suitable for the operating condition of small flow rate, and the structure of tank type liquid distributor is more complicated, occupies space in larger tower, does not have the performance of anti-clogging simultaneously.The initial uniform distribution of liquid of the defective effect of these traditional liquid distributors, reduce the separative efficiency of packed tower, therefore developing distributes liquid distributor is significant work.
The Fluor Daniel of the U.S. be the whole world maximum be engaged in the engineering company that oil plant builds.Henry Z.Kister is chief rectifying expert of Fluor Daniel, and he writes two very important books " Distillation Operation " and " Distillation Design ".Two books have all done detailed discussion to the design of rectifying column with operation.In book, Mr.Kister points out that multi-nozzle distributor liquid point uniformity is not necessarily best, but it is very welcome for (as vacuum tower) in the short system of filling batch.Because at these short packed bed places, the liquid sprayed by nozzle just has very large heat and mass effect after self contacting with gas, this contributes to the heat and mass transport effect of obviously taking out high whole packed bed.In addition Mr.Kister to the selecting of multi-nozzle distributor, design and also proposed 8 guiding principles.Wherein just introduce multi-nozzle distributor for the 6th article, also likely blocked, the impact of corrosion, but lower to the sensitiveness of blocking.And blocking causes to multi-nozzle distributor to flow through in the liquid of nozzle contained solid often, instead of the solid of entrained with in ascending air.
But common multi-nozzle distributor, due to the problem of self structure, there will be the phenomenon of serious liquid distribution inequality.As shown in Figure 3,4, this type of distributor is employing one supervisor 7 chargings, and many arms 8 are connected side by side with supervisor, is responsible for and arm is connected corresponding nozzle 9.Liquid enters from the right-hand member of supervisor, and directly rush at high order end arm, the kinetic energy of liquid is all converted into pressure energy herein.This just causes pressure herein maximum, props up pipe pressure from left to right and reduces successively, and the pressure at low order end arm place is minimum.We know that liquid flow is that depended on pressure promotes, pressure greatly then in same time flow large, otherwise, pressure little then in same time flow just little.Pressure non-uniform causes non-uniform on tower section amasss of emitted dose, makes the flow on the left side large the right flow little.
If this type of distributor spray height is selected incorrect simultaneously, also there will be a large amount of Liquid inject on tower wall 10, cause wall flow phenomenon, (partial filler layer 11 liquid is more for a large amount of overlap of the liquid phase of the nozzle ejection simultaneously area of coverage, part is less), these drawbacks all have a strong impact on the mass-and heat-transfer efficiency of packing layer.
Summary of the invention

The technical solution of the utility model is: the branched cast liquid distribution trough of a kind of network structure, comprises supervisor, Liquid distribution case, many arms and several nozzles; Described supervisor is the feed pipe that one end is connected with nozzle flange, one end is connected with Liquid distribution case; Described Liquid distribution case is polygon column structure, top is connected with supervisor, the side correspondence that each limit of the section polygon of described polygon cylinder is corresponding connects first arm, and be connected with the second arm between all two adjacent the first arms, make the many arms be interconnected be made up of the first arm and the first arm form network structure; Described nozzle is evenly distributed on arm, and ejection even in liquid phase can be made to be distributed on the filler of below.
Further, the second arm is connected with between the distalmost end of two adjacent the first arm distance Liquid distribution casees.2/to three/2nds places and 5/2 to six/3rds places of each first arm distance Liquid distribution case respectively open a hole; Two adjacent the first arms: first arm distance Liquid distribution case 2/1 to three/2nds place a bit, with adjacent first arm distance Liquid distribution case 5/2 to six/3rds place a bit, between connect the second arm.The nozzle be arranged on arm is evenly distributed, ensures that ejection even in liquid phase is distributed on the filler of below.
Further, all arm sectional areas and be supervisor 1 ~ 2 times of sectional area.Ensure liquid communication speed and pressure uniform.
Further, described nozzle inclination is downward, and the angle between horizontal plane is 40 ° ~ 120 °.Liquid phase can be sprayed onto on the filler of below uniformly.
The beneficial effects of the utility model are: first charging squeezes into supervisor, then Liquid distribution case is entered, liquid is in the short stay of distributor box back warp, divergent shape is become to deliver to Ta Bichu by arm again after making each limit pressure of distributor box identical, and each arm is all mutual UNICOM, make whole distributor form one be communicated with overall and do not have pressure dead angle, the pressure namely arriving each nozzle is all identical, and namely fluid flow is all identical in same time.If spray height is suitable for, Ta Bishang will be sprayed onto without liquid phase, avoid wall flow phenomenon, and the liquid phase overlapping region being sprayed onto filler upper surface is little, liquid phase clear area is also little, make the sprinkle density of on filler often closer to, reach the object being uniformly distributed liquid phase.Adopt the nozzle lower to the sensitiveness of blocking, anti-clogging is good simultaneously.
