Combined wheel plate type evaporator condenser

Abstract

The invention discloses an evaporation-condensation structure used in water treatment field and chemical and refrigeration industry technological process, which comprises a set of rotary disc evaporators, and plate type condensers arranged in parallel to the disc surfaces of the rotary disc evaporators. The evaporation-condensation structure is characterized in that the plate surfaces of the plate type condensers and the disc surfaces of the rotary disc evaporators are staggered, a space between the disc surface and pipe wall is 0-50mm, and the plate type condensers are arranged below the rotary disc evaporators. The combined wheel plate type evaporator condenser can realize 100% evaporation of liquid on the evaporation surface and condensation vapor-liquid tank heat exchange of small temperature difference lower than 3 DEG C in the condenser, and has very high heat exchange efficiency.

Description

technical field [0001] The process of endothermic evaporation and exothermic condensation widely exists in the field of water treatment and in the process flow of chemical and refrigeration industries, and these two processes often exist at the same time. The efficiency of the evaporator and condenser affects the energy consumption of the entire system. Efficiency can be decisive. The invention relates to a combined wheel-plate evaporator and condenser, which is suitable for process equipment with two heat exchange processes of evaporation and condensation. This combined wheel-plate evaporator and condenser structure consists of a disc rotary evaporator section and a stationary heat exchange plate condenser section. Background technique [0002] In the water treatment field and in the process flow of the chemical industry and refrigeration industry, there are two heat transfer processes of evaporation and condensation at the same time. At present, their process equipment u...

Problems solved by technology

Since the spray liquid of the spray evaporator cannot be completely evaporated, the unevaporated droplets fall back into the liquid pool, thus wasting the pump work for raising its gravitational potential energy, resulting in work loss

However, the sewage pipeline circulation of the traditional condenser currently used requires a large-flow sewage circulation pump (generally, the circulation volume is 1000 times the evaporation volume)

This circulation pump needs to consume a lot of pump work, making it difficult for the entire water treatment system to obtain high system efficiency, which is why compressed steam distillation has become a low-efficiency water treatment method that no one cares about.
