The invention belongs to the field of chemical equipment and relates to a tower bottom gas distributor which is used after material gas of a rectifying tower enters the rectifying tower and before pipeline gas, namely rising gas in the tower, enters a filler layer. The tower bottom gas distributor comprises a bottom plate, wherein a ventilation supporting ring is fixedly arranged on a through hole in the middle of the bottom plate; the upper end face of the ventilation supporting ring is provided with a plurality of gas-liquid collection and expansion inclined plates in a welding manner; a connection plate is arranged between the adjacent two gas-liquid collection and expansion inclined plates; connection pressing strips are welded on the upper parts of the gas-liquid collection and expansion inclined plates; two liquid overflowing holes are uniformly formed in the bottom plate; liquid baffling rings are welded on the upper surface of the bottom plate and correspond to outer rings of the liquid overflowing holes. According to the distributor, the gas does not go off course in the tower; the gas raises at one circle close to a tower wall except a middle channel; the aims that a load enters the filler layer to carry out gas-liquid exchange and the uniform distribution is reached are realized.
Description
technical field [0001] The invention belongs to the field of chemical equipment, and relates to a gas distributor used for rectification tower feed gas entering the tower from pipeline gas as rising gas in the tower before entering the packing layer. Background technique [0002] Due to the unreasonable structural design of the gas distributor often used in the rectification tower in the prior art, the gas bias flow occurs in the first packing layer at the bottom of the tower and the gas-liquid distribution effect is reduced; some companies even suffer from the lack of suitable gas distribution instead of using a gas distributor in the column. According to relevant industry standards, gas distributors must be used for towers above φ1500mm. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a gas distributor at the bottom of the tower with a simple, ingenious and reasonable structure. Liquid ...
