Embodiment Construction

[0029] The present invention is described in further detail below in conjunction with accompanying drawing:

[0030] Such as figure 1 As shown, it is a film tube row falling film evaporation tube bundle according to the present invention, which includes a plurality of heat exchange tubes 1 and deflectors 2 .

[0031] The heat exchange tube 1 works in the falling film evaporator, the heat exchange tube 1 is arranged horizontally, a plurality of heat exchange tubes 1 are arranged in parallel in a row, and the two ends of the heat exchange tube 1 are the inlet and outlet of the cooled working fluid respectively, for It is connected to the pipeline that transmits the cooled working fluid. A row of heat exchange tubes 1 is a group of tube bundles, and multiple groups of tube bundles are arranged side by side.

[0032] Such as figure 2 with image 3 As shown, the top and bottom surfaces of the adjacent heat exchange tubes 1 in the same group of tube bundles are connected by def...

Abstract

The invention discloses a film type tube row falling film evaporation tube bundle. The film type tube row falling film evaporation tube bundle comprises a plurality of heat exchange tubes and flow guide plates; the heat exchange pipes are horizontally arranged; the plurality of heat exchange pipes are arranged in a row in parallel; the top faces and the bottom faces of the adjacent heat exchange pipes are connected through the flow guide plates; the long edges of the flow guide plates make contact with the heat exchange pipes; the short edges of the flow guide plates are vertically arranged; the flow guide plates are arranged at the bottom of the lowest heat exchange pipe; and the flow guide plates and the heat exchange pipes are made of the same material. The liquid film can completely cover the surfaces of the heat exchange tubes, and drying is avoided.

Description

technical field [0001] The invention belongs to the field of falling film evaporators and relates to a film tube row falling film evaporation tube bundle. Background technique [0002] As a kind of high-efficiency evaporation equipment, the falling film evaporator is widely used in the fields of sugar production, refrigeration, ocean heat energy conversion, food processing, sewage treatment, waste heat utilization, and solar heat utilization. The tube bundle of the horizontal tube falling film evaporator is a gas-liquid two-phase flow. The uneven distribution of the liquid film and the dryness of the heat exchange surface will affect the heat transfer efficiency and the safe operation of the equipment. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a film-type tube row falling film evaporation tube bundle, which is beneficial to completely cover the surface of the heat e...
