used to close contact in order to promote the mutual transfer of vapor or gas and liquid. Column is provided with a multi-layer horizontal plate, the plate has a plurality of vapor supply (or gas) by short, cover the bottom margin of a slot or small slot in the bubble cap, and is provided with an overflow pipe.

Operation, liquid from the upper part of the tower in a row of, through the overflow pipe by plate on the decline, and fluid accumulation layers on each plate, forming sealing liquid; steam (gas) is from the bottom of the tower into, through the bubble on the bottom of the cover on the edge of the slot or minor groove dispersed into small bubbles, and liquid full contact, and through the liquid layer and up to the surface and ascend to a layer of tower plate. The short pipe is arranged tower, referred to as the inner overflow; there are also installed in the tower in, outside overflow. Bubble column are widely used in distillation and gas absorption.

Features:

1. Efficient

2. The whole tower pressure reduction, generally 5 block, the whole tower pressure drop is less than 400mm water column.

3. Easy to operate, stable and reliable.

4. Tray with reinforcing structure, safe and reliable and optional Hastelloy alloy heat exchange tube, reduce the concentration of H₂SO₄ temperature and partial pressure, improve the drying efficiency.

5. The blister cover is made of special technology, which is very simple to maintain and replace once injection molding.

6. The blister cover is made of special technology, which is very simple to maintain and replace once injection molding.
