Abstract

The invention relates to a seawater desalination evaporator. The seawater desalination evaporator of the invention allows problems that the output of fresh water is influenced and the operation of a seawater desalination system may deviate from an initial design value caused by a case that there are gaps among two sides of a tube bank of a present seawater desalination evaporator and a structuralmember of the present seawater desalination evaporator to be solved. The seawater desalination evaporator of the invention is characterized in that: a plurality of support plates of a tube bank of the evaporator which are arranged in a housing of the evaporator in a horizontal direction are used for supporting the heat exchange tube bank of the evaporator; two baffle plates of the tube bank of the evaporator are respectively arranged on two sides of the heat exchange tube bank of the evaporator, a plurality of seawater reflux buffer plates are arranged on the outer side of the heat exchange tube tank of the evaporator along the direction of the heat exchange tube tank of the evaporator; and one side of each seawater reflux baffle plate is fixed on the baffle plates of the tube bank of theevaporator, and the other side of each seawater reflux baffle plate extends into a slit between heat exchange tubes of the heat exchange tube bank of the evaporator. The seawater desalination evaporator of the invention is applied to seawater desalination evaporators.

Description

technical field [0001] The invention relates to a seawater desalination evaporator, in particular to a seawater desalination evaporator with a seawater return component. Background technique [0002] The low-temperature multi-effect seawater desalination system is that the seawater is sprayed on the tube bundle area from the top of the evaporator tube bundle through nozzles, and evaporated to obtain fresh water. In the thermal calculation of the seawater desalination system, the calculation of the evaporation of seawater is based on the complete attachment of the material seawater to the heat exchange tube bundle and the heat exchange performed by the heating steam. However, in the existing seawater desalination evaporator, because there is a gap between the two sides of the evaporator tube bundle and the evaporator structure, part of the seawater will flow into the concentrated brine area through this space after being sprayed from the seawater nozzle, and it will also adhe...
