Tail gas scrubbing tower adopting gas-liquid separation membrane

Abstract

The invention relates to a tail gas scrubbing tower adopting gas-liquid separation membrane. The tail gas scrubbing tower is composed of a tower body (1) and a fixing part located on the lower portionof the tower body (1), the tower body (1) comprises a top portion (11), a bottom portion (13) and a middle portion (12), wherein the top portion (11) is in an arc cover shape and located on the upperportion of the tower body (1), the bottom portion (13) is in an arc cover shape and located on the lower portion of the tower body (1), and the middle portion (12) is in a hollow cylindrical shape and located between the top portion (11) and the bottom portion (13); the tail gas scrubbing tower is characterized in that the inner portion of the tower body (1) is separated into a top escaping cavity (1m), a first separation cavity (1n), a second separation cavity (1p) and a bottom sedimentary cavity (1q) through a first separation membrane (1j), a second separation membrane (1k) and a third separation membrane (1l) which are arranged sequentially from top to bottom; and the first separation membrane (1j), the second separation membrane (1k) and the third separation membrane (1l) are provided with micropores allowing gas to pass through but not allowing liquid to pass through; the gas-liquid separation membrane is adopted, the gas-liquid separation effect is improved, thereby being conductive to the effective discharge of gas, the cost is low, the later cleaning and maintenance are convenient, and the use is convenient.

Description

technical field [0001] The invention relates to the field of tail gas purification, in particular to a tail gas scrubber using a gas-liquid separation membrane. Background technique [0002] The washing tower is a new type of gas purification treatment equipment, which is improved on the basis of the floating packing layer gas purifier, and is widely used in the pre- and post-processing work of industrial waste gas purification and dust removal; in the prior art There is usually no special gas-liquid separation device inside the exhaust gas scrubber, which results in poor gas-liquid separation after washing. The washed gas contains more washing liquid components, which is not convenient for the effective discharge of gas and affects the equipment. Service life; while the tail gas scrubber with a special gas-liquid separation device is installed inside, the gas-liquid separation device is expensive, and installed inside the tail gas scrubber, it is not easy to clean and maint...
