Abstract
The invented tower is composed of tower body, tower board and liquid dropping pipes, the tower board is fixed between the liquid dropping pipes, on the tower board there are fixed sloped holes and floated sloped holes for gas passing through. The liquid dropping pipe is a square trough and is composed of liquid dropping board and bottom board, the liquid dropping board is fixed on the tower body, the bottom board is connected to the liquid dropping board, on the bottom board the liquid flowing out port is opened. Said tower can effectively lower the tower height, reduce the tower diameter, save investment. Compared with double overflow floating valve tower, said tower increases the processing capability by 50%, saves energy by 10% and lowers the tower resistance by1/3 odd.
Description
The invention relates to a kind of multiple overflow compound inclined holes tower for distillation, belong to the chemical industry equipment field.
Existing plate column kind is a lot, the tower that wherein has a downspout by the overflow pattern can be divided into single overflow, double overflow, overflow stream and multi-overflow etc. are several.The downflow weir length of single overflow tower generally is no more than 0.8 times of tower diameter, only is applicable to the less system of liquid phase load.The downflow weir length of double overflow tower is longer than single overflow tower, but also is not suitable for the very big system of liquid phase load.The stream tower that overflows can be used for the very big system of liquid phase load, but the shared area of downspout and seal pot is bigger, and the utilization rate of tower is lower.
The multi-overflow sieve-plate tower is a kind of more advanced tower of big liquid phase load system of handling.The downspout of this tower is made of many square downcomer parallel to each other, and the diverse location every downspout bottom has liquid flowing outlet and flows out for liquid.The total length of this tower downflow weir is more a lot of greatly than general tower, and the liquid layer on the column plate is lower, can adopt less distance between plates.This tower does not have seal pot, so tower diameter is also little than the common stream tower that overflows.The shortcoming of this tower is that downspout quantity is too many, the complex structure of tower, installation and maintenance inconvenience, the cost height, distance between the downspout is shorter in addition, the time of staying of liquid on column plate is shorter, therefore plate efficiency is lower than common tower, because column plate adopts sieve plate, the flux ratio of vapour phase load is less.
The object of the present invention is to provide a kind of multiple overflow compound inclined holes tower for distillation simple in structure, overcome the shortcoming of above-mentioned prior art, both improved the liquid phase load disposal ability of tower, improve the vapour phase load disposal ability of tower again.
Multiple overflow compound inclined holes tower for distillation of the present invention is made up of tower body, column plate and downspout.Having fixedly on the column plate, inclined hole and unsteady inclined hole supplied gas pass through; Downspout is a square groove, is made up of down-flow plate and base plate, and the downflow weir of its down-flow plate is the profile of tooth weir, and downspout is fixed on the tower body, also can be fixed on the column plate.Base plate is connected the bottom of down-flow plate, and liquid flowing outlet is arranged on the base plate.Gas from column plate below by the perforate on the column plate with enter the last layer column plate after liquid on the column plate fully contacts; Liquid fully contacts the back with gas and flows into contiguous downspout on column plate, the liquid flowing outlet on the downspout base plate flows to down the diverse location of one deck column plate then.
The quantity of downspout is generally one or two, is no more than the six roots of sensation at most.
Illustrate that accompanying drawing is as follows:
Fig. 1 is a compound inclined holes tower structural representation of the present invention.
Fig. 2 is the shape schematic diagram of liquid flowing outlet on the downspout base plate.
Accompanying drawings is implemented as follows:
Fig. 1 is a structural representation of the present invention, and wherein 1 is tower body, and 2 is column plate, and 3 is downspout, 4 is the downspout base plate, and 5 is the liquid flowing outlet on the downspout base plate, and 6 are the inclined hole that floats, 7 are fixing inclined hole, and 8 is down-flow plate, and liquid flowing outlet can be rectangle, garden shape, shape fond of gossip, tubaeform etc.The downflow weir of down-flow plate (8) can be that the profile of tooth weir also can be flat weir.The quantity of downspout can be more than one or one, is no more than the six roots of sensation at most.
Fig. 2 is the shape schematic diagram of liquid flowing outlet on the downspout base plate, and wherein 9 is Long Circle, and 10 is circular, and 11 is rectangle, and 12 is tubaeform, and 13 is shape fond of gossip.
The course of work that this tower is described is as follows:
By contacting with liquid on the column plate 2 after fixing inclined hole 7 and the unsteady inclined hole 6, the generation mass transfer enters a column plate later on to gas from the below of column plate 2; Liquid contacts with gas on column plate 2, takes place to cross down-flow plate 8 and enter downspout base plate 4 after the mass transfer, and by flowing into one deck column plate down after the liquid flowing outlet 5.Liquid during by liquid flowing outlet 5 since resistance act on the certain liquid layer of formation in the downspout, prevent that gas from directly passing downspout.
The length of downspout of the present invention is far longer than common tower, can process very big liquid phase load and with The time guarantee that the efficient of tower does not reduce. Because downspout generally only has one or two, tower relatively simple for structure, Cost compare is low, and installation and maintenance are all more convenient. In addition, because the quantity of downspout is few, liquid is at tower Mobile distance on the plate is long, and the efficient of column plate is higher. Column plate adopts the very big composite inclined of disposal ability Hole column plate, entrainment is little, and distance between plates can be lower than common column plate. Downflow weir adopts the profile of tooth weir, so that overflow Liquid layer on the stream weir distributes more even. Adopt the present invention can effectively reduce the height of tower, reduce tower diameter, Reduce investment outlay, compare with the double overflow valve tower, can improve disposal ability 50%, energy-conservation 10%, the resistance of tower Reduce more than 1/3.
The present invention can be widely used in many row such as oil refining, petrochemical industry, fine chemistry industry, pharmacy, chemical fertilizer The rectifying column of industry, absorption tower, desorber etc. are specially adapted to the very big system of liquid phase load. The present invention both Can be used for transforming old tower, improve disposal ability, reduce investment outlay, can be used for again designing new tower, reduce tower Footpath and tower height reduce cost.
