Abstract
The utility model relates to a side-draw or middle feeding device placed in a packing layer, which is characterized by mainly comprising a porous baffle plate, a multi-tube baffle plate and a feeding and discharging tube, wherein the porous baffle plate is mounted on the inner wall of a rectifying tower, the multi-tube baffle plate parallel to the porous baffle plate is mounted on the inner wall of the rectifying tower, the feeding and discharging tube is horizontally mounted on the wall of the rectifying tower, one end of the feeding and discharging tube is arranged between the porous baffle plate and the multi-tube baffle plate in the rectifying tower, and the other end of the feeding and discharging tube extends out of the rectifying tower. Compared with the prior art, the side-draw or middle feeding device has the advantages of high operation flexibility, low pressure drop, no entrainment, less equipment investment, small occupied space, high practicability and applicability to not only draw in the packing layer but also feeding in the packing layer.
Description
Technical field:
The utility model relates to a kind of chemical industry equipment, is specifically related to a kind of device of realizing side line discharging in the packing layer or intermediate feed, is applied in the material filling type rectifying column.
Background technology:
Separate a plurality of products on the rectifying column for being implemented in, usually side line extraction device can be set on rectifying column, realize quantitative extraction.If through feeding material in the material extraction Guan Xiangta of this extraction device, this moment, this extraction device just became the intermediate feed device.
More side line extraction device adopts groove type distributor and liquid header to cooperate or adopts slotted disc type gas-liquid redistributor at present, selects for use the structure of which kind of form to depend on the filler model usually.No matter adopt which kind of structure, the axial height of needed tower for example adopts liquid header and tank type liquid distributor structure combining all than higher, and the height that it needs is about 1.8 meters; Adopt the structure of slotted disc type vapour-liquid redistributor, the height that it needs is about 1.2 meters.
According to factors such as filler model and tower diameter sizes, every section filler piling height is slightly different, usually about 5 meters.Usually be arranged on normal segmentation place of filler when at present side line extraction device being set on rectifying column, realize the quantitative extraction of side line through the design of this section tower internals.But may not be the position of best extraction here, perhaps raw material is formed when changing, and the quantitative extraction that moves side line herein may cause the increase of operating cost.
Patent No. ZL200720043425.6 " side line discharging gatherer ", this utility model need connect with flange, is applied to trourelle more.The liquid phase time of staying is short, and gas phase entrained drip phenomenon is difficult to avoid.Because it does not possess the function of packing support plate and filler pressing, so can not be applied between packing layer.And vapour, liquid phase loading elasticity are low.
Patent No. ZL200820034292.0 " side line discharging and partial reflux distribution coupling apparatus ", this utility model realizes full extraction, partial reflux is to realize forced refluence through pump after the full extraction of liquid phase.Can not the design through tower internals realize satisfying remaining fluid after the quantitative extraction and continue the function that refluxes mutually.
The utility model content
It is big in high-efficiency packing tower, to take the tower body axial space to present side line extraction device, is not arranged on the realistic situation in the packing layer flexibly, and the purpose of the utility model is to provide a kind of tower internals, as extraction of packed tower side line or intermediate feed device.
The purpose of the utility model realizes through following technical scheme:
A kind of side line extraction or intermediate feed device that places packing layer; It is characterized in that; Mainly comprise with lower component: be installed on the perforated baffle on the rectifying column inwall; Parallel multitube baffle plate and the level that is installed on the rectifying column inwall with perforated baffle is installed in the feed and exhaust tube on the rectifying column wall, and the one of which end is located between interior perforated baffle of rectifying column and the multitube baffle plate, and the other end stretches out outside the rectifying column.
Compared with prior art, the beneficial effect of the utility model is: be not only applicable to the situation of extraction in the packing layer, also be applicable to the situation of charging in the packing layer; Operating flexibility is high, and pressure drop is low, and nothing is carried secretly; Equipment investment is few, and it is low to take up room, practical.

The specific embodiment
Referring to Fig. 1; A kind of side line extraction or intermediate feed device that places packing layer; It is characterized in that, mainly comprise with lower component: be installed on the perforated baffle 2 on rectifying column 1 inwall, the parallel multitube baffle plate 6 that is installed on the rectifying column inwall with perforated baffle is installed in the feed and exhaust tube 4 on the rectifying column wall with level; The one of which end is located between interior perforated baffle of rectifying column and the multitube baffle plate, and the other end stretches out outside the rectifying column.Feed and exhaust tube both can the extraction liquid material, also can feed liquid, gas material.
Referring to Fig. 2, described perforated baffle is a plectane that is provided with 2 above through holes 3, and these through holes can let vapour-liquid material easy on and off walk; The perforated baffle level is installed on the rectifying column inwall, and its diameter is identical with the rectifying column internal diameter.
Referring to Fig. 3, described multitube baffle plate 6 is the plectanes that are vertically installed with 2 above pipes 5 above, and its diameter is identical with the rectifying column internal diameter, and these pipe two ends are all open-minded.
The position of described feed and exhaust tube is lower than the upper end of the pipe 5 on the multitube baffle plate.
The upper end of the pipe on the described multitube baffle plate is all equally high, and the lower end all follows the baffle plate lower surface concordant, and these pipes can let vapour-liquid material easy on and off walk.
The above filler of placing of described perforated baffle, the multitube baffle plate is not placed filler with the held filler between perforated baffle and the multitube baffle plate.
During the rectifying column operation,, accumulate on the multitube baffle plate, when liquid level exceeds the upper surface of pipe on the multitube baffle plate, just flow to downwards in the following filler through pipe through the liquid material that perforated baffle flows down; The gas material can pass through multitube baffle plate and perforated baffle, upwards flows swimmingly.The input and output material mouth of pipe buries in the liquid on the multitube baffle plate, can make things convenient for the liquid in the extraction tower.Perhaps, can in tower, feed liquid or gas material through feed and exhaust tube easily.
