Abstract

The invention discloses a method and device using selectivity active film to purifying gas. A selectivity active film reactor mainly comprises a selectivity active film generator and a gas purification absorption cavity. The gas to be purified is fed to the inlet of the selectivity active film reactor and passes through the active film generator. The gas to be separated is generated and wrapped by the active film in a bubble mode, the object component is absorbed by the generation liquor of the selectivity active film, and the absorption liquor flows out of a film separator; the purified gas is discharged through a vent. The method of the invention has the advantages of non-block, good separation effect, energy saving, easy operation and so on, and is applicable for treating various gas pollution, such as flue gas, natural gas, car exhaust and oil smoke etc., and air purification.

Description

Background technique

[0001] The invention relates to a method for purifying gas, in particular to a method and equipment for purifying gas by using a selective active membrane. technical field

[0002] At present, there are many kinds of known gas purification methods and purification equipment, and the purification mechanism involves many aspects such as solid adsorption, liquid absorption, physical separation and chemical conversion. Defects such as narrow range. For example, the well-known coal-fired boiler tail gas treatment adopts dry or wet desulfurization and denitrification technologies. The dry methods mainly include lime method and ammonia method. After lime method desulfurization, a large amount of waste residue is difficult to handle, causing secondary pollution; investment in dry ammonia method desulfurization Big and expensive to run. According to relevant literature published at home and abroad, most of the natural gas desulfurization technologies require re...
