Description

Technical Field

[0001] The utility model relates to the field of evaporators, in particular to an infrared heating evaporator. Background Art

[0002] A heating evaporator is a device that uses external heating to convert liquid into gas or steam. In chemical production, a heating evaporator is often used to heat a liquid containing a solution and evaporate it to obtain the desired pure solution. The working principle of the heating evaporator is to heat the heated material by heat transfer or conduction, so that it undergoes a phase change, that is, from a liquid state to a gas or steam state. In the heating evaporator, the heating surface dissipates heat to the heated material, raising the temperature of the material to meet the conditions for evaporation. When the material reaches saturation concentration, the material content in the material can no longer be increased. At this time, increasing the temperature can convert the solution into the desired pure solution.

[0003] The heating steam used in the existing heating evaporator can be irradiated onto the heated liquid through the infrared radiator. In addition to being reflected and transmitted, the rest is absorbed by the liquid and converted into thermal motion of the material molecules, so that the liquid is heated to generate steam. However, the existing infrared heating evaporator still has the following problems during use:

[0004] The raw material liquid of the existing heating evaporator is circulated through a connecting pipe. Under the action of heating steam, condensate is formed on the surface of the connecting pipe. If the condensate is not cleaned in time, the hot steam contacts the condensate to reduce the heating temperature, so that the superheated steam affects the heating effect of the raw material liquid in the connecting pipe. Therefore, it is very necessary to involve an infrared heating evaporator for use in the existing evaporator field. Utility Model Content
