Technical Field
The utility model belongs to the technical field of the rectifying column accessory and specifically relates to a be applicable to the collection of accurate rectification in-process liquid, concretely relates to collect liquid collector of liquid fast.
Background
The liquid collector is one of the important internal parts of the rectifying tower, mainly used for completely collecting and mixing the liquid flowing down from the upper bed layer when the packing of the rectifying tower is segmented so as to be redistributed or extracted, and meanwhile, the liquid collector is also one of the main factors influencing the gas distribution in the rectifying tower.
In the operation process of the rectifying tower, the deviation of gas-liquid flow rate can cause different local gas-liquid ratios, so that the radial concentration difference appears on the section of the tower, if the gas-liquid ratios are not mixed in time, the efficiency of the filler can be influenced, and the uniformity of gas distribution in the tower directly influences the performance of the filler tower.
The pressure drop is also a very important indicator for a rectification column, in particular a rectification column operating under vacuum conditions. When the packing is selected, the design of the liquid collector must also take into consideration that the resistance to the fluid (especially gas) must be small, and therefore the liquid collector for collecting the liquid rapidly must have a large enough gas passage area.
At present, the liquid collector mainly comprises a fin type liquid collector and a disc type liquid collector, wherein most of the liquid collectors are complex in structure, inconvenient to install and maintain, large in resistance in the working process and uneven in gas distribution, and the liquid collecting plate is extremely easy to deform due to large gas-liquid scouring amount, so that the separation effect of the filler is influenced. Therefore, there is a need to develop a liquid collector which has a simple structure, is convenient to install and maintain, has small resistance in the working process, and can quickly collect liquid with uniform gas distribution.
CN203620642U provides a fin-type liquid collector in the prior art, which includes a liquid collecting main plate, a liquid collecting sub-plate, a liquid collecting main tank, a liquid collecting sub-tank and a liquid collecting tray, wherein the liquid collecting main plate is radially and symmetrically arranged on the tank plate of the liquid collecting main tank, the liquid collecting sub-tanks are fixedly arranged on the support rods at two sides of the liquid collecting main tank at intervals, the liquid collecting sub-tank is obliquely arranged on one of the tank plates of each liquid collecting sub-tank, and the liquid collecting sub-plates are also at intervals, i.e. a gap exists between adjacent liquid collecting sub-plates, liquid in the tower easily splashes when the liquid washes the liquid collecting sub-plates, and splashed liquid leaks to the next bed layer through the gap.
