Problems solved by technology

[0002] The current single-effect evaporator for vacuum evaporation, the evaporator is a conventional free-fall type, and the evaporation effect is not good. The steam-water ratio is about 1:1, that is, one ton of steam is consumed for evaporating one ton of water, and the energy consumption is very large.
In order to prevent the corrosion of the evaporating liquid (such as sulfuric acid), the existing single-effect evaporator is usually lined with special anti-corrosion materials, such as lining lead or lining rubber, etc., the cost is very high

Abstract

The invention relates to an evaporator with a multi-fold flow mode. The evaporator comprises a ball-shaped evaporation tank. Parallel liquid distribution plates are arranged below a liquid baffle, a filtering screen is arranged below the liquid distribution plates in the horizontal direction, the include angles between the filtering screen and the liquid distribution plates are 15-25 degrees respectively, a filler layer is arranged below the filtering screen, and a liquid collecting plate is arranged below the filler layer; a base is arranged under the evaporation tank and provided with a square cavity, and a discharge opening is formed in one side of the lower end of the square cavity. The evaporator is provided with the multi-layer baffling and filler layer structure, so that evaporation liquid is changed from a conventional free falling mode into a filler seepage and sliding mode, so that the contact face of the evaporator and vacuum is increased, and the vapor-water ratio is reduced.

Description

technical field [0001] The invention relates to an evaporator with multi-fold flow mode. Background technique [0002] The current vacuum evaporation single-effect evaporator, the evaporator is a conventional free-fall type, and the evaporation effect is not good. The steam-water ratio is about 1:1, that is, one ton of steam is consumed for evaporating one ton of water, and the energy consumption is very large. In order to prevent the corrosion of the evaporating liquid (such as sulfuric acid), the existing single-effect evaporator is usually lined with special anti-corrosion materials, such as lead-lined or rubber-lined, which is very expensive. Contents of the invention [0003] The purpose of the present invention is to provide a single-effect evaporator with low cost, increased evaporating liquid, multi-layer baffles and packing in order to solve the shortcomings of the above-mentioned technologies. [0004] In order to achieve the above purpose, the evaporator design...
