Description
Technical field
The invention belongs to technical field of chemical, especially relate to a kind of middle-size and small-size packed tower.
Background technology
Packed tower is one of the most frequently used gas-liquid mass transfer (contact) equipment, and it is widely used in the processes such as distillation, absorption, desorb, stripping, extraction, Chemical Exchange, washing and heat exchange.The tower body of packed tower is vertical type cylinder, and supporting plate is equipped with in bottom, and filler is to huddle or the mode of whole block is placed on support plate.Above filler, hold-down grid is installed, to limit the motion of filler with ascending air.Liquid adds from tower top, sprays on filler through liquid distribution trough, and flows down along filling surface.Gas is sent at the bottom of tower, after gas distributor distribution, is the space that adverse current continues through packing layer with liquid, and on filling surface, mass transfer is carried out in gas-liquid two-phase contact.
In order to save manufacturing cost and packed tower can be saved energy and reduce the cost in running, increasing middle-size and small-size packed tower obtains and uses widely.Then the tower internals being applicable to middle-size and small-size packed tower is still fewer, and structure is reasonable not, have impact on the rectification efficiency of middle-size and small-size packed tower.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, uses reliable, the middle-size and small-size packed tower that rectification effect is good.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A kind of middle-size and small-size packed tower, comprises tower body, liquid distribution trough, filler, gripper shoe and gas distributor; The top of described tower body is provided with liquid distribution trough; The below of described liquid distribution trough is provided with the gripper shoe for supporting filler; Gas distributor is provided with below described gripper shoe; Described filler is that catalytic filler layer and structured filling material layer from top to bottom stack gradually on the supporting plate; Described liquid distribution trough is the one piece of ring flat-plate be fixed on tower body inwall; Below the middle duct of this ring flat-plate, every sky, cylinder distributing slot is installed; The bottom land of described cylinder distributing slot is provided with liquid distribution orifice again; Described liquid again distribution orifice is provided with liquid pores.
Above-described catalytic filler layer is the spring that regular packing box comprises packing layer between upper and lower two boards net, expanded metals and expanded metals side and arranges along expanded metals even width, and the length of expanded metals is equal with its length, and even concentric circular fashion rolls in the shape of a spiral.
A shallow shape ringlet is connected with below the edge, middle duct of above-described ring flat-plate; The inner ring diameter of described shallow shape ringlet is less than the inner ring diameter of cylinder distributing slot.
The vertical grid blank that above-described gripper shoe comprises horizontal screen, bracing ring and is fixed in bracing ring, also comprises twice angular slope and rib symmetrical mutually; Described rib and horizontal screen, vertical grid blank form " rice " shape.
The angle of inclination of above-described rib is respectively 45 degree and 135 degree.
Relative to prior art, the present invention has the following advantages and beneficial effect:
1, structured packing disk seal is contained between two expanded metals by the present invention, adds the gap between concentrically ringed expanded metals and spring, and the whole filler being has abundant circulation passage, avoids dead band and the imperfect flow of liquid.Meanwhile, increase the voidage of filler, reduce pressure drop, liquid phase can fully react.
The Set scale of the gas-liquid channel of the liquid distribution trough 2, in the present invention more easily controls, and fluid passage is not by the constraint of gas passage, makes the setting of liquid pores more flexible, adds the distribution density of liquid, be applicable to middle-size and small-size packed tower.
3, gripper shoe of the present invention is provided with twice rib, makes to concentrate the polygonal net lattice structures such as triangular in shape or rhombus in the middle part of supportive grid, makes gripper shoe not yielding, can support filler better.
4, of the present invention rational in infrastructure, use reliable, rectification effect is good, is suitable for wide popularization and application.
