Liquid feed distributor for lamella heat exchanger

Abstract

The invention discloses a liquid feed distributor for a lamella heat exchanger, comprising a feed access pipe and a feed distribution pipe. The liquid feed distributor is independently arranged outside a gas pipeline, and the feed distribution pipe of the liquid feed distributor is provided with a plurality of rows of distribution holes along the radial direction; one end of the feed access pipe of the liquid feed distributor is communicated with the pipe wall at the outer end of the feed distribution pipe; the feed distributor is connected with a plate bundle of the lamella heat exchanger through the feed distribution pipe; a part of the plurality of distribution holes of the feed distribution pipe along the radial direction are positioned in the plate bundle; both the outer end of the feed distribution pipe and the feed access pipe are positioned outside the plate bundle; and the outer end of the feed distribution pipe is provided with an end flange. The invention can solve the problem of distribution dead zones in the center of an original distributor structure and reduce the overhaul workload and the overhaul difficulty of the distributor on the premise of realizing uniform distribution.

Description

technical field [0001] The invention relates to a liquid feed distributor structure for a plate and shell heat exchanger. Background technique [0002] The plate and shell heat exchanger is an advanced heat exchanger structure in the world at present. The plate heat exchange element is used to replace the rubber gasket seal of the ordinary plate heat exchanger by welding and sealing, which greatly improves the performance of the plate heat exchanger. operating temperature and pressure capacity. [0003] In the plate and shell feed heat exchanger, the cold material is composed of two process media, liquid feed and circulating gas. Internal mixing, the mixing effect directly affects the heat exchange efficiency of the heat exchanger, and the mixing effect depends on the distribution of the liquid feed distributor. [0004] In the existing feed heat exchanger, the distributor usually adopts a central tube or T-shaped structure, and its main feature is that the feed pipeline i...
