Biological trickle-bed reactor for purification of gas method for purification of gas

摘要

The subject of the invention is a trickle-bed reactor and a method of purifying gas particularly the air from volatile organic compounds and their sparingly water soluble mixtures.A trickle-bed reactor for purifying gas according to the invention is characteristic in that in the tank (1) there is at least one layer of inert packing (3) covered with an active biofilm of microorganisms and a sprinkler (2) placed in the top part of the tank (1) between the gas inlet (4) and the packing (3), wherein the outlet of the purified gas (5) is located in the bottom part of the side surface of the tank (1), and in the cone-shaped bottom (6) there are valves (7) for the system controlling the level of the circulating liquid. The method of purifying gas is characteristic in that the gas is transported cocurrently with the liquid through aninert packing bedcovered with an active biofilter of microorganisms, wherein the packing bed is being continuously sprinkled with mineral salts solution in the amount ranging between 5 and 20 m3/m2 h, and the gas to be purified is distributed evenly around each sprinkling point.
