Mist purification tower installation considerations and purification process sequence principle (1) hood - inlet pipe - fan (or inlet section) - the first paragraph of the inlet section of the filter layer (first stage reaction section) - The second stage filter layer (the second stage and the reaction stage) cyclone - a hood cover - exhaust pipe (or suction fan section) (2) mist purification tower works: mist purification tower uses sodium hydroxide solution for absorption and liquid mist to purify exhaust gases. Gas from the centrifugal fan pushed or sucked into the wind section, and then flows upward to the first filter layer, with the first stage nozzle and spray the liquid contact reactions. After absorption of the exhaust gas continues to flow upwardly through the second filter layer, and in liquid contact with the ejection nozzle of the second stage, the neutralization reaction occurs again, and then through the swirl plate, the hood and into the exhaust duct or fan atmosphere. Installation Notes 1, for polypropylene-based mist purification tower mounting surface, should ensure that the same horizontal plane, clean bottoms Conditions foot bolts or fixed on the basis of Da connected to the buried plate. 2, polypropylene fan installation, should prevent debris fall into the fan. After purification tower installation is complete, the test must be removed before the tower dirt. Due to general polypropylene flammable, installation and maintenance process, prohibited the use of fire. 3, the concentration of NaOH solution liquid storage tank should be kept within the range of 8-16%, while less than 2% NaOH concentration, must be filled with NaOH solution or replacement of the NaOH solution. Waste liquid storage tank should be replaced based on actual usage. 4, such as polypropylene fan installed in the room, the fan motor rain measures should be taken. For PP purification tower metal stents were embalmed at least twice a year.
