Description

Decarburization tower with high decarburization efficiency

Technical Field

The utility model relates to the technical field of decarburization towers, in particular to a decarburization tower with high decarburization efficiency.

Background

The current ion exchange system process is: cation exchanger- & gt decarburization tower- & gt intermediate water tank- & gt anion exchanger. The decarburization tower has the following functions: the effluent of the cation bed contains a large amount of bicarbonate HCO 3-which combines with H+ in the water to form carbonic acid H2CO3. The carbon dioxide remover is used for removing CO2 gas in the water of the positive bed so as to reduce heavy carbonate radicals entering the water of the negative bed. When raw water passes through the cation resin, cations in the water are adsorbed, H+ carried by the resin is replaced into the water, so that the water is acidic, when the PH is less than 4, the water almost exists in a carbon dioxide gas form, and if the PH is not removed, the carbon dioxide gas reacts with the anion resin, so that the exchange capacity of the anion resin is shortened, the working period is shortened, and the water production cost is increased.

The working principle of the existing decarbonization tower is that according to henry's law, in a certain volume of solution, the dissolved gas content is in direct proportion to the partial pressure of the gas on the liquid level, when a decarbonization fan blows air into the tower, packing is filled in the tower to increase the contact area between the water of a cation bed and the air, when the water of the cation bed flows downwards from the tower, and in the process of the air flowing upwards from the bottom, the partial pressure of CO2 gas in the air is far smaller than the partial pressure of CO2 in the water of the cation bed, so that the CO2 gas in the water escapes.

In the prior art, a part of air after the air enters the fan easily flows out from the water outlet, and the effect of carrying carbon dioxide cannot be achieved, so that the working efficiency of the decarburization tower is reduced.
