Description

Technical Field

[0001] The utility model relates to the technical field of ammonia water evaporation, in particular to an ammonia water evaporator. Background Art

[0002] Ammonia evaporator is a device that uses heat energy to evaporate ammonia gas from ammonia water. It is widely used in chemical industry, environmental protection and other fields. Ammonia gas is a colorless gas with a strong irritating odor. It can burn the skin, eyes and mucous membranes of respiratory organs. If people inhale too much, it can cause lung swelling and even death.

[0003] During the evaporation of ammonia water, steam enters the evaporator shell through the pipeline and exchanges heat with the ammonia water in the tube. In this process, steam condenses, releases heat, and cools down, while ammonia water absorbs heat, heats up, and evaporates, eventually becoming an ammonia mixture. Usually, the ammonia mixture is discharged directly. Direct discharge without detecting the ammonia may result in incomplete treatment of ammonia and a high concentration. Direct discharge may affect the atmosphere and cause pollution. Long-term inhalation is harmful to the human body. When the water in the insulation box is heated by the heater, there is no temperature detection device, and the heating temperature of the water cannot be determined. The generated ammonia mixture may enter the insulation box from the air inlet, resulting in incomplete discharge. After searching, it was found that the technical solution provided by the utility model with application number 202320194556.3 also has the above-mentioned problems. Utility Model Content
