Evaporative type condenser

Abstract

The invention discloses an evaporative type condenser. The evaporative type condenser comprises a frame, a water tank which is arranged at the bottom of the frame, a water distribution assembly which is provided with a first flow channel used for allowing cooling water to flow, and a heat exchange assembly. The heat exchange assembly comprises a plurality of heat exchange plates which are arranged inside the frame in parallel at intervals. The top of each heat exchange plate is located in the water distribution assembly, a plurality of gaps are formed between the outer wall face of each heat exchange plate and the wall face of the water distribution assembly making contact with the corresponding heat exchange plate at intervals, and each gap communicates with the first flow channel. Each heat exchange plate is provided with a cavity allowing steam to be condensed to flow. A second flow channel is formed between any two adjacent heat exchange plates, and the top of each second flow channel communicates with the corresponding gaps. The bottom of each second flow channel communicates with the water tank. At least one second flow channel and / or a cavity of at least one heat exchange plate are / is internally provided with supporting assemblies. The evaporative type condenser is high in heat transfer efficiency, small in steam resistance, compact in structure, and convenient to manufacture, install and maintain.

Description

technical field [0001] The invention relates to industrial heat exchange equipment, in particular to an evaporative condenser. Background technique [0002] The evaporative condenser is a highly efficient condensation heat exchange equipment. Since the 1970s, developed countries began to replace the traditional circulating water-cooled condenser with evaporative condensers. Compared with the traditional circulating water-cooled condenser, the evaporation The shell-and-tube condenser is equivalent to the integration of the shell-and-tube condenser and the cooling tower, which saves the cooling tower and related pipelines, makes full use of the latent heat of vaporization of the cooling water, occupies a small area, and has low power consumption of the water cycle. It has obvious advantages in construction cost, so it is widely used in refrigeration, chemical industry, metallurgy, pharmaceutical and other fields. [0003] At present, the heat exchange unit of the evaporative ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an evaporative heat exchanger to overcome the defects of low heat exchange efficiency, large steam flow resistance and uneven distribution of cooling water on the heat exchange plate in the traditional evaporative heat exchanger in the prior art. Condenser, the evaporative condenser has high heat transfer efficiency, small steam flow resistance, compact structure, and is easy to manufacture, install and maintain
