Description

Technical Field

[0001] The utility model relates to the field of evaporators, in particular to an evaporator for separating vapor and liquid. Background Art

[0002] The working principle of the evaporator for vapor-liquid separation is mainly as follows:

[0003] Heating evaporation: The liquid is heated in the evaporator, and part of the liquid is converted into gas after absorbing heat.

[0004] Gas-liquid mixing: forming a gas-liquid mixed state.

[0005] Separation process: Due to the different densities of gas and liquid, the gas will move upward in the evaporator, while the liquid will flow downward under the action of gravity.

[0006] Gas phase discharge: Gaseous substances are discharged through a specific outlet or channel to achieve separation from the liquid.

[0007] Liquid collection: The liquid is collected or continues to circulate in the evaporator for further processing.

[0008] For example, in industrial production, after some solutions are heated by an evaporator, the generated steam is separated for other purposes, and the concentrated solution can be further processed. Another example is in the evaporator of an air conditioner, the refrigerant liquid is heated and evaporated into a gas state, which is separated from the liquid refrigerant, and the gaseous refrigerant enters the compressor for circulation. In this way, the vapor-liquid separation process is completed, and the corresponding process or system operation requirements are met; when the evaporator removes water containing natural gas, the removal efficiency is low, therefore, the utility model provides an evaporator for vapor-liquid separation.
