The phosphate fertilizer and fluoroplastics of industry produce；Cupola furnace of foundry industry etc. will discharge a large amount of waste gas containing fluoride.
The main method of purifying waste gas containing fluorine has wet absorption and Dry Adsorption.Dry cleaning processing, is straight with aluminium oxide
Absorption hydrogen fluoride is connect, and obtains fluoro-containing alumina.Wet absorption technique system uses liquid absorption method, washes by liquid fluorine-containing useless
Gas can reach the purpose of Recovery Purifying.Waste gas absorption in the prior art is mostly directly absorbed, however for the height of generation
If warm exhaust gas is also directly absorbed, the problem of absorbing liquid being caused to overheat.When the temperature increases, adsorption effect is deteriorated.Together
When, when high-temp waste gas is just contacted with absorbing liquid, or even absorbing liquid can be made to generate slightly boiling, common absorption equipment will produce not
The influence of profit.
Therefore, it is necessary to develop a kind of processing unit specifically for high temperature waste gas containing fluoride.
Invention content
In order to overcome the above problem, the present invention to provide a kind of processing unit suitable for high temperature waste gas containing fluoride, cooling early period
Effect is good, and the later stage absorbs abundant.
