A distributor of horizontal falling film evaporator

Abstract

The present invention discloses a distributer of a horizontal falling film evaporator. The distributer comprises distribution pipe, a distribution tank and a falling film evaporation pipe, wherein the bottom of the distribution pipe is provided with primary distribution holes, various pipe holes are uniformly distributed, the distribution tank is arranged below the distribution pipe, presents a tapered shape, and is connected with the distribution pipe through a welding manner, the lower half portion of the distribution tank is filled with a porous material, a separation plate is longitudinally arranged to separate the distribution tank into mutually-noncommunicated areas, the bottom of the distribution tank is provided with uniformly-distributed secondary distribution holes, both sides of the secondary distribution holes are embedded with draining projections for providing a draining effect, the falling film evaporation pipe is positioned just below the distributer, the positions of the secondary distribution holes and the draining projections are just toward the axis center of the falling film evaporation pipe, both ends of the falling film evaporation pipe are sealed by using flanges and washers, and the distribution pipe and the distribution tank are respectively connected with the horizontal falling film evaporation cylinder body through welding. The distributer has characteristics of simple structure, easy installation processing, uniform film distribution, increased evaporator efficiency, and energy source saving.

Description

technical field [0001] The invention relates to a distributor of a horizontal falling film evaporator, which is a matching device of the falling film evaporator and belongs to the technical field of evaporation equipment. Background technique [0002] Falling film evaporator, as an efficient evaporation equipment, is widely used in various industries such as food, chemical industry, light industry and seawater desalination. The function of the distributor of the horizontal falling film evaporator is to distribute the feed liquid evenly on the falling film evaporation tube, and evenly distribute the film along the outside of the tube. Whether its structure is reasonable or not will directly affect the distribution of the liquid and the film forming effect. The heat transfer efficiency is related to the production capacity, product quality and equipment life of the evaporator. [0003] At present, in the existing tubular spray distributor in the horizontal falling film evapor...
