Abstract
The utility model relates to a plate type spiral ladder-shaped fractionating tower. Tower plates are arranged in adjacent fractionating zones in a body of the tower, wherein the tower plates are spatially staggered and are arranged in parallel. Pipe gas-phase distributors and baffle weirs are arranged on the tower plates, and all the tower plates form a sealed spiral ladder shape in the body of the tower. The utility model can make gas-phase flow in the body of the tower ascend in a spiral ladder shape and make liquid-phase flow descend in a spiral ladder shape, liquid phases form an S-shaped flow direction from a liquid receiving zone to a liquid descending zone, therefore the liquid phases can be distributed on the tower plates more uniformly to further improve fractionating effects. Therefore, the utility model overcomes the defect of the prior art that the gas-phase flow ascends in a linear shape and the liquid-phase flow descends in an S shape to cause big space of liquid descending differential pressure. Under the condition of ensuring the same efficiency of the tower plates, the height of the body of the fractionating tower is decreased by about 70%. Simultaneously, the fractionating tower has the advantages of convenient installation, convenient maintenance and low cost.
Description
Technical field
The utility model relates to the trapezoidal fractionating column of a kind of fractionating column, particularly slab type spiral, and it is applicable to the separated of the various solution of chemical industry.
Background technology
Usually, chemical industry is to the normal board-like fractionating column that adopts of the separated of solution, mainly, be positioned at tower body and be the upper and lower column plate of layout and the gas phase distributor that upward is provided with thereof, the compositions such as liquid phase downflow weir, downspout of paralleling in twos of vertical type by skirt and connected tower body.Because the distance between the adjacent upper and lower layer column plate that parallels in twos is to set according to relevant specification requirement, and all column plate is again to be the upper and lower in twos shape that parallels of vertical type to arrange, so the body of the tower of this fractionating column is taller and bigger, this brings difficulty not only for the installation of fractionating column, and, also make maintenance very inconvenient, cost is than higher.
The utility model content
The purpose of this utility model is to provide a kind of slab type spiral trapezoidal fractionating column, and it can overcome the deficiency of prior art, guaranteeing under the situation of plate efficiency effectively the height of tower body to be reduced significantly, reaches about 70%.
Its solution is: the column plate in the adjacent fractionation zone in tower body is that the space interlaces and parallel layout again, and column plate is provided with tubular type gas phase distributor and baffling weir, and all column plates form the cocke-stair shape that seals in tower body.And the tower body inner chamber is divided into fractionation zone more than the secondary by circumference.
Described tubular type gas phase distributor is responsible for by the gas phase distributor and arm intersects connects and constitutes, and is distributed with gas-phase distribution hole on the gas phase distributor branch pipes.
The utility model mainly is, is provided with the column plate that is that the space interlaces and parallels layout again in the adjacent fractionation zone in the fractionation tower body, and tubular type gas phase distributor and baffling weir are arranged on the column plate, and all column plates form the cocke-stair shape that seals in tower body.It can make the trapezoidal in the shape of a spiral rising of gas phase flow process in the tower body, and the trapezoidal in the shape of a spiral decline of liquid phase flow process, because every layer of column plate is provided with the baffling weir, liquid phase forms the serpentine flow direction from liquid receiving area to falling the liquid zone, thereby liquid phase is more evenly distributed on column plate, can further improve fractionating effect.Thus, can overcome prior art and be the serpentine very big defective of falling the hydraulic pressure difference space that causes that descends because of the gas phase flow process liquid phase flow process that linearly rises.Under the situation that guarantees identical plate efficiency, can make the tower body height of fractionating column reduce about 70%.This can not only make the fractionating column installation, maintenance convenient, and can also reduce production costs.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Among Fig. 1, Fig. 2, with tower body 13 that skirt 14 is connected in, by division board 7 inner chamber of tower body 13 is divided into three parts, form three grades of fractionation zones.Column plate 11 in the adjacent fractionation zone is that the space interlaces and parallel layout again, and the center angle α of every block of column plate 11=120 °, column plate 11 is provided with tubular type gas phase distributor, it by the gas phase distributor be responsible for 6 and gas phase distributor branch pipes 4 intersect and connect and constitute, on gas phase distributor branch pipes 4, be evenly equipped with gas-phase distribution hole 12, also be provided with downflow weir 3 and baffling weir 5 on 11 on the column plate, and downspout 15 is connected between the two adjacent column plates 11.Tower body 13 is by end socket 8 sealings.Liquid phase outlet 1 is arranged in the bottom surface of tower body 13, and bottom one side has gas phase inlet 2, and gaseous phase outlet 9 is arranged on the end face of tower body 13, and upper side has liquid phase inlet 10.
After gas phase enters tower body 13 by gas phase inlet 2, through the gas phase distributor with enter after liquid phase on the bottom column plate 11 carries out Medium Exchange, spiral escalation step by step, and after carrying out Medium Exchange from the gas phase that liquid phase inlet 10 enters liquid phase on the top layer column plate 11 and rising, descend step by step by downspout 15, thereby can realize the separated of solution.
Among Fig. 3, Fig. 4, in tower body 13, tower body 13 inner chamber five equilibriums are isolated into four parts, form the level Four fractionation zone by division board 7, and the center angle of every block of column plate 16 be β=90 ° other all with embodiment 1.
Among Fig. 5, Fig. 6, in tower body 13, tower body 13 inner chamber five equilibriums are isolated into five parts, form the Pyatyi fractionation zone by division board 7, and the center angle r=72 of every block of column plate 17 °, other is all with embodiment 1.
