Abstract

The invention discloses a vertical pipe falling film evaporator, which comprises a plurality of evaporation units which are detachably connected with one another to form a rectangular array, a shell of each evaporation unit comprises a cylinder body, an upper sealing head and a lower sealing head, the upper sealing head and the lower sealing head are arranged at the two ends of the cylinder body, the cylinder body is cuboid, and each evaporation unit comprises a film distribution section, a heating section and a separation section from top to bottom; a first connecting assembly is used for communicating the heating steam of each row of evaporation units; a second connecting assembly is used for communicating the condensed water of each row of evaporation units; and a third connecting assemblies communicate the secondary steam of each row of evaporation units, and the third connecting assemblies are arranged in each row of evaporation units in an up-down staggered mode, so that the secondary steam reversely flows in the adjacent evaporation units. According to the vertical pipe falling film evaporator, the modular evaporation units are detachably connected into the rectangular array, the heating steam, the condensate water and the secondary steam in the rectangular array form a specific path to be communicated, large-scale production of the vertical pipe falling film evaporator is achieved, and the handling capacity of the evaporator is improved.

Description

technical field [0001] The invention relates to the field of evaporation equipment, in particular to a vertical tube falling film evaporator. Background technique [0002] As a high-efficiency evaporation equipment, vertical tube falling film evaporator has been widely used in seawater desalination, sewage treatment, petrochemical industry, metallurgy, light industry, food processing, medicine and other fields due to its unique advantages. Under the trend of energy saving and emission reduction, with the development of the national economy, the processing capacity of standpipe falling film evaporators is required to increase in seawater desalination and sewage treatment. At present, the processing capacity of a single evaporator can only reach 200-300 tons per hour, which brings great challenges to the design, construction and operation of vertical tube falling film evaporators. [0003] In the prior art, the processing capacity of the evaporator is mainly increased by impr...
