Abstract
The utility model relates to a composite tower plate used in a mass transfer separation device, and more especially, a float valve and screen hole composite tower plate is designed, wherein circular screen holes and float valves are arranged on the tower plate; the gradient of the liquid level from an inlet to an outlet of the tower plate can be reduced by the special arrangement of the float valves; no liquid stagnation region and uniform gas distribution promote the gas-liquid mass transfer on the tower plate, and the efficiency of the tower plates is high. The combination of the float valves and the screen holes can increase the operation load range of the tower plates and the treatment capability is large. The manufacture cost of the tower plates is low, and is between the cost of a screen plate tower and the cost of a float valve tower.
Description
Technical field
The utility model patent relates to a kind of composite plate that is used for mass transfer separation equipment, and the composite plate of round sieve and float valve is arranged on particularly a kind of column plate.
Background technology
The advantage of industrial sieve-plate tower is simple in structure, and dependable performance is cheap.But there is the uneven distribution of gas and liquid in sieve-plate tower, and back-mixing is bigger, and average mass transfer force is reduced, and plate efficiency is low, and have sieve-plate tower structures shape the less shortcoming of operating flexibility of sieve-plate tower.
Valve tower is provided with unsteady cover plate-float valve above the column plate perforate, can regulate aperture voluntarily according to the flow of gas.Valve block is in low level when low discharge, and aperture is less, and gas still passes through annular space with enough gas speed, avoids in the dead of night too much; Valve block floats automatically when high tolerance, and aperture increases, and makes gas speed unlikely too high, thus the pressure drop when having reduced high gas speed, and the liquid flooding gas speed of column plate improves, so under high gas-liquid ratio L/V, the production capacity of valve plate is big.In sum, the advantage of valve tower is that operating flexibility is big, the plate efficiency height.But it is complicated that its structure is still disliked, owing to adopted movement parts, increased difficulty of processing.
Along with the development of industrial technology, design shortcoming that a kind of composite plate has the advantage of sieve-plate tower and valve tower simultaneously concurrently and overcome single type become chemical separating an urgent demand.
Summary of the invention
The utility model technical issues that need to address are design a kind of float valve-sieve aperture composite plates, to overcome the above-mentioned defective that prior art exists.
Float valve of the present utility model-sieve aperture composite plate comprises column plate and the float valve that is provided with sieve aperture, and column plate is provided with valve opening, and said float valve is floatable to be fixed in the valve opening.
Advantage of the present invention is very significant,
Because round sieve aperture and float valve are integrated on the column plate, sieve aperture and float valve are arranged on the column plate, not only can reduce the gradient of liquid level that column plate enters the mouth to and exports, the no liquid stagnant area, distribution of gas is even, promotes the gas-liquid mass transfer on the column plate, the plate efficiency height, and the combination of float valve and sieve aperture can improve the operational load scope of column plate greatly, and disposal ability is big.The processing cost of column plate is lower, between sieve-plate tower and valve tower.Experimental result shows that the composite plate that the utility model relates to combines the advantage of sieve-plate tower and valve tower, can be widely used in reducing pressure, the absorption under normal pressure and the pressurized conditions, rectifying etc. separate process.Simple in structure, reliable, float valve is installed maintenance conveniently, and processing cost is low, compares with single valve tower, saves cost 10～30%.Disposal ability is big, and the disposal ability of comparing composite plate with common sieve-plate tower can increase more than 10%.The gas-liquid contact condition is good on the plate, and gradient of liquid level obviously reduces, no liquid stagnant area on the plate, thereby plate efficiency obviously improves, and compares with common sieve-plate tower, plate efficiency can increase by 10～30%.
