Product introduction:Jiangsu absorber tower (Suzhou absorption tower, Wuxi absorption tower, Changzhou absorber) glass fiber reinforced plastic co.! Yixing absorption tower, Jiangyin tower, Changshu absorption tower, Kunshan absorption tower, Nantong
Absorption tower is a device for absorbing operation. There are three types according to the gas-liquid contact morphology. The first is the gas dispersion in liquid phase plate tower, bubble absorption tower, bubble absorption tower to form bubbles; the second is the liquid dispersion in the injector, venturi tube, spraying tower gas phase to liquid droplet; third kinds of liquid film in motion and gas phase contact filler the absorption tower and the falling film absorption tower. Flow pattern of gas-liquid countercurrent flow and can also be. Countercurrent operation is usually adopted, the absorber is added to the top of the tower to flow from top to bottom, and the gas flowing from the bottom to the top is contacted. Jiangsu FRP Co., Ltd.
Absorption tower should have the following basic requirements:
The 1 column of gas and liquid in sufficient contact area and contact time.
2 gas-liquid two has strong disturbance, reduce mass transfer resistance and improve absorption efficiency.
3 wide operating range, stable operation.
4 equipment resistance, low energy consumption.
5 with sufficient mechanical strength and corrosion resistance.
6 simple structure, easy to manufacture and maintenance.
Common types of absorption tower:
[packing tower]
The import by the shell, packing, packing support, liquid distributor, intermediate support and re distribution, the gas and the liquid inlet pipe and other parts, multi tower shell made of metal material, can also be used in plastic manufacturing.
Packing is the core of the packing tower, which provides a gas-liquid contact surface, the structure of filler and determines the performance of the tower tower.
Filler must have a larger specific surface, high porosity, good wettability, corrosion resistance, certain mechanical strength, low density, low price, etc..
The commonly used packing with Rasching rings, Bauer ring, arc saddle and Intalox saddle packing model, in 1980s after the development of QH-1 type flat ring packing and 84 inner ring, hedgehog shaped filler metal plate, corrugated plate packing, packing, regular grid filling, provide the basis for the design of advanced packing tower.
The packed column is suitable for fast and transient absorption processes.
The tower has the advantages of simple structure, easy fabrication of corrosion resistant material, gas-liquid contact area, the contact time is long, strong adaptability of gas tower, tower resistance, pressure loss is 300 ~ 700Pa, and compared the plate tower volume small, empty tower gas velocity is usually 0.5 ~ 1.2m/s, the formation of flooding gas velocity and the spray density of 6 ~ 8m3/ (m2, H) to ensure that the filler wetting, liquid gas ratio control in 2 ~ 10L/m3.
The packed tower should not be handled a large amount of dust, should be designed to overcome the problem of uneven distribution of gas-liquid.
Turbulent ball tower
It is a special form of packing tower, tower packing operation in motion, in order to strengthen the absorption process.
Put a certain number in the tower gate plate between the light ball filler (29 ~ 38mm in diameter), absorbent from the top of the tower under the spray, wet ball surface, gas enters from the bottom of the tower, the ball is blown turbulence due to rotation, full contact of the gas liquid solid phase, small liquid film on the surface of constantly updated, increasing the absorption driving force, improve the absorption efficiency.
The utility model has the advantages of convenient manufacture, installation and maintenance, and the utility model can change the operating range with small size and different quality balls.
The tower to deal with large air volume, air velocity of air tower 1.5 ~ 6.0m/s, spray density of 20 ~ 110m3/ (M2 ~ H), the pressure loss of 1500 ~ 3 800Pa, but also can deal with dust laden gas.
The disadvantage is that plastic balls can not withstand high temperatures, the ball is easy to crack (generally 0.5 ~ 1 years), need to be replaced frequently, high cost.
[plate tower]
The plate tower is equipped with plate layers of liquid from the tower top in the tower. When the gas enters from the bottom of the tower, the mass transfer and heat transfer of the gas and liquid are carried out on each tray.
There are many types of plate tower.
Can be divided into two categories: one is the downcomer, such as bubble tower, sieve plate tower, float valve tower, S tower, one-way flow plate tongue plate tower, floating spray tower; the other is through flow type plate tower, such as the turbogrid plate (shower trays tower), corrugated turbogrid tower, diamond slant hole plate tower, short turbogrid tower etc..
The sieve plate tower
Sieve diameter generally 5 ~ 10mm, the total area of the sieve area accounted for 10% ~ 18% plate.
In order to make the plate liquid layer on a uniform thickness, is provided with a sieve overflow weir, the liquid layer thickness is about 40Mn, the wind screen empty tower is about 1 ~ 3.5m/s, sieve holes gas velocity of 6 ~ 13m/s, 300 ~ 600Pa per layer plate resistance.
The sieve plate tower mainly has the advantages of simple structure, large air handling, and gas processing dust.
The deficiency is clogging clean up more trouble, the tower installation requirements strictly, tray level should be maintained; the operation elasticity is small.
The cable trays
Cable trays is another form of sieve plate tower. Inclined hole width 10 ~ 20m, length of 10 ~ 15mm, high 6mm. Empty tower gas velocity is 1 ~ 3.5m/s, 10 ~ 15m/s sieve air velocity.
The gas ejected from the horizontal oblique hole, hole direction of two adjacent holes in staggered liquid through the overflow weir for to tray (weir height 30mm), and the airflow direction vertical flow, turbulence caused by the height of the gas to liquid surface is constantly updated, full gas-liquid contact, better mass transfer effect, high purification efficiency, at the same time gas processing dust, easy to plug, each layer plate resistance is about 400 ~ 600Pa.
The tower structure is more complex than the sieve plate tower, difficult manufacture, installation requirements strictly, prone to drift.
The venturi tube absorber
Absorption tower should have the following basic requirements:
The 1 column of gas and liquid in sufficient contact area and contact time.
2 gas-liquid two has strong disturbance, reduce mass transfer resistance and improve absorption efficiency.
3 wide operating range, stable operation.
