Hualai Tower Interals Structured Packing Supporting Grids Fine Made

 

The main purpose of the packing support plate is to support the packing in the tower, and at the same time to ensure the smooth passage of gas and liquid phases. The basic requirements are:

 

1. It has enough strength and rigidity, and can support the quality of packing and liquid holding as well as the operating pressure, etc;

2. It has an opening ratio greater than the void ratio of the packing layer to prevent flooding at this position;

3. The structure is reasonable, which is conducive to the uniform distribution of gas and liquid phases, small resistance and easy to disassemble.

 

Due to the inherent structural characteristics of structured packing, the supporting device used is simple in structure. The supporting grid plate of corrugated structured packing has a spacing of 50-100mm, and the lower end of the grid bar is zigzag, so that the liquid can drop evenly from the tip of the tooth. For the small tower with flange connection (the diameter of the tower is usually less than 1 m), it can be made into an integral type. It is made of 3-10 mm thick flat steel. The height of the support ring and grid bar is 50-100 mm. It is placed on the tower ring welded on the tower wall or on 4-8 supports welded on the tower wall. These dimensions depend on the weight it bears.

For the tower with manhole, the supporting grid plate can be made into section type and assembled from the manhole into the tower. If the tower diameter is more than 2m, multiple supporting beams shall be added. The support beam can be made of I-beam, the support grid plate is placed on it, and the periphery is also placed on the tower support ring.

 

General failure analysis and treatment of packed tower:

 

Phenomenon Possible cause of failure Advice
Tower efficiency is low, product quality is poor, but packing pressure drop is normal

It is mainly caused by uneven liquid distributor

1. Poor design, liquid overload range;

2. Poor installation levelness;

3. The liquid distributor is blocked;

4. Liquid distributor leaks due to medium corrosion

1. Improve the design, increase or decrease the opening of distributor;

2. Reinstall and adjust the level;

3. Remove the blockage;

4. New distributor made of more corrosion resistant material

Low efficiency of tower and low pressure drop of packing Too loose packing installation or too large clearance with tower wall Install as required. Temporary measures to increase return flow can improve efficiency.
The packing pressure drop is large, and the operation upper limit capacity is reduced

1. The metal filler is installed too tightly and has large deformation;

2. There are many broken ceramic fillers

1. Install as required. Temporary measures to reduce the operating load can improve the efficiency of the tower;

2. Remove debris. Temporary measures to reduce the operation load.

The product yield of the upper side is low, that of the lower side is light and that of the lower side is high The oil collecting tank on the upper side is not sealed, and there is oil leakage downward. Repair unsealed areas or reinstall.
Unable to reach the design capacity, flooding ahead of time, low tower efficiency.

1. The opening rate of packing support plate is low;

2. Low opening rate of packing press plate

1. Replace with high opening rate support plate;

2. Replace with high opening rate pressing plate.

After a period of operation, the pressure drop increases gradually, the efficiency decreases, and the load capacity decreases Packing blocked and coking Clean or replace packing
After operation for a period of time, the pressure drop fluctuates from high to low, and the efficiency decreases The packing is corroded Replace the anti-corrosion material filler
After a period of operation, the quality of the product decreases and the color becomes heavier

1. The wire mesh of metal demister is corroded

2. The wire mesh of metal demister is blocked or twisted to form re-entrainment.

1. Replace the anti-corrosion material demister;

2. Replace the demister with high void ratio
