Abstract

The invention discloses a composite-pipe type liquid distribution device. A feeding pipe is sleeved with a communication pipe, wherein two ends of the communication pipe are respectively connected with a connection flange plate and a plugging flange plate of the feeding pipe correspondingly; liquid distribution holes, which are distributed at equal intervals, are formed in the bottom of a plane of the communication pipe; liquid distribution pipes are respectively formed by butting a front-section liquid distribution pipe and a rear-section liquid distribution pipe which are arranged at the inner side and the outer side of the communication pipe; liquid outlet holes are formed in an upper half pipe body of the rear-section liquid distribution pipe; the rear-section liquid distribution pipe is sleeved with liquid distribution outer pipes and communicated with the communication pipe; liquid tanks and liquid distribution holes, which are distributed at equal intervals, are formed in the bottoms of pipe bodies of the liquid distribution outer pipes. The communication pipe and the liquid distribution outer pipes essentially form a secondary pipe type liquid distributor; kinetic energy of liquid in the distributor in any section is zero; the liquid in the distributor only has potential energy or static energy; liquid levels of the distribution outer pipes are kept on the same horizontal plane through the communication pipe, so that liquid volumes of the liquid flowing out of the distribution holes of the distribution outer pipes always remain equal. The composite-pipe type liquid distribution device has the characteristics of compact structure, uniformity in liquid distribution and great operating flexibility.

Description

technical field [0001] The invention belongs to a liquid distribution device of a packed tower, in particular to a composite tube type liquid distribution device. Background technique [0002] The high-performance gas-liquid distribution device is the guarantee to give full play to the performance of the packing, improve the mass transfer efficiency and production capacity of the packing. At present, great progress has been made in the research and development of gas-liquid distribution devices for towers at home and abroad, and the design and application are becoming more and more perfect. [0003] The existing tubular liquid distributors of various structural forms including gravity type and pressure type have different characteristics, but there are still deficiencies of one kind or another to varying degrees. For example, the height of the gravity type liquid level pipe still needs 200-500mm , resulting in an increase in the axial size of the tower, which increases the ...
