Abstract
The fractional column of float valve of one kind gas-liquid mass transfer (contact) equipment adopts the rectangle air rising hole, and the float valve on each hole is by two different sizes, and the rectangular flat type valve block of different-thickness is formed.According to the variation of gas load, two valve blocks can open simultaneously, or only open little valve block, and are bigger to the accommodation of load variations.This tower gas becomes single way jet, and the material lagging time is short, is difficult for forming new impurity.Hydraulic gradient and entrainment are little on the plate, and the gas-liquid boundary line helps strengthening mass transport process and improves plate efficiency greater than general valve tower.Float valve does not need a device of limiting in addition, and is simple in structure, easy to process.
Description
The invention relates to a kind of gas-liquid mass transfer (contact) equipment, particularly when gas load changes, can automatic adjustments of gas pass through regional a kind of float valve essence in a big way
Tower.
Valve tower is to use wider a kind of novel gas-liquid mass transfer apparatus on the chemical industry, and its performance is better than bubble column and packed tower.The general float valve pattern that adopts is a lot of in the prior art, and commonly used have a F
1Type, the V-4 type, cross type etc., but these float valves are in working order down, and gas is ejection towards periphery in horizontal direction under the shape valve disc of garden, and the gas of adjacent two valves ejection liquidates, and is easy to generate entrainment during high cycle speed.And the liquid phase material on the column plate is subjected to the injection that liquidates of all directions gas, and gas-liquid contact time is long, and not only air-teturning mixed phenomenon is serious, and may make storeroom produce new reaction, forms new impurity.Among the Japanese kokai publication sho 54-92573 disclosed a kind of valve plate be single current to column plate, it has solved the shortcoming that gas liquidates and sprays, but valve block is made with fan-shaped material, two sides are turned back, and form baffle plate, every valve device of must limiting in addition, complex structure, make trouble, and two side shields influences gas-liquid and contact, unfavorable to mass transfer.Also, big inadequately to gas load accommodation because its valve is the single valve sheet.
These shortcomings in view of valve tower in the prior art exists the objective of the invention is, and provide a kind of simple in structure, the plate efficiency height, and the stronger single current of the adaptive capacity that gas load is changed is to float valve type essence
Tower.
Solution of the present invention is essence
Have equally distributed rectangle air rising hole (5) on the column plate of tower, the orientation on the long and short limit of each rectangular opening is consistent.(dispose float valve (4) on 5, it is made up of a big young waiter in a wineshop or an inn who overlaps each other a rectangular flat type valve block each air rising hole.Big valve block (6) inserts two other valve pedal apertures of peritreme (9) of air rising hole (5) respectively with two the valves foots (8) that stretch out on long limit of its rectangle (7), and (10) Nei ， And are to the crooked certain angle β of this hole direction
1And can rotate to an angle around this peritreme (9) on the column plate and be fixed on, have rectangle air rising hole (11) on this big valve block (6), little valve block (12) inserts the two other valve pedal apertures of peritreme (7) of this hole (11) with two the valves foots (14) that stretch out on the long limit of one rectangle (13), and (16) Nei ， And are to the crooked certain angle α of this hole direction
1Can rotate to an angle around this peritreme (15) and be fixed on big valve block Shang ， And.When gas load was zero, large and small valve block was topped respectively on air rising hole (5) and (11).Because the size on each limit of rectangle of each valve block is slightly larger than the size of its topped air rising hole (5) and (11) each corresponding sides, the extreme lower position that valve block descends is to drop on the peritreme, so the double stopping means for valve decline of each peritreme, needn't set in addition and fall stopping means.H-Max angle [alpha], the β that each valve block rotates up is the bent angle alpha by its valve foot (8), (14)

1Placed restrictions on, i.e. α=α
1, β=β
1Needn't establish the rising stopping means in addition.
The slab-thickness of the big valve block of valve among the present invention (4) is less than the slab-thickness of big valve block (6), gas load hour, little valve block (12) is because of in light weight, resistance is little and at first open, when gas load increased to certain degree, big valve block (6) opened in succession.Therefore, essence of the present invention
Tower can adapt to bigger load variations, even under the less situation of load, also can carry out gas-liquid mass transfer effectively by little valve block.
Adopt above-mentioned flat double-valve float valve essence
Tower and since each valve valve block open the direction unanimity, single way jet impacts the liquid phase material on the column plate, makes material form one-way flow, thereby rate of flow of fluid increases, material onboard the holdup time short, make essence
The intensity that forms impurity in the process greatly weakens.Hydraulic gradient and entrainment are little on the plate, and its vapour-liquid contact boundary line helps strengthening mass transport process and improves smart than ending V-1 type valve tower increase about 1.2 commonly used
Separative efficiency.
In sum, float valve essence of the present invention
Tower, it is simple in structure, and is big to load accommodation owing to adopt the float valve of double valve sheet, the gas unidirectional ejection, material holdup time on column plate is short, be difficult for forming new impurity, and hydraulic gradient and entrainment is little on the plate essence
The efficient height.

In the present embodiment, the processing of outer cylinder body (1) and each column plate (2), chord downcomer (3) downflow weir (17) and packaging technology and general smart
Tower is identical, rectangle air rising hole (5) cross arrangement equably on each column plate (2), difference parallel (as Fig. 8) between each long limit of rectangular opening and each minor face, the valve pedal aperture leaves the same side in each rectangular opening, direction is opened facing to each valve in downspout position on the column plate, makes to form the following current column plate.Zone under the big valve opening in each column plate edge is arranged not remedies (as Fig. 8) with little valve opening (11), to increase percent opening and to avoid producing " dead angle " zone.
