[0002] An evaporator is a device that uses heat to convert solutes (such as water) in a liquid into a gaseous or vaporous form. In the treatment of ammonia-containing wastewater, evaporators are typically used to evaporate the water from the wastewater, thereby separating the ammonia from the water. Ammonia is an irritant that is extremely harmful to the human body and can also cause environmental pollution. When using an evaporator to separate ammonia from wastewater, improper sealing of pipe joints or wear and tear over time can cause ammonia leaks. If not detected in time, they can be harmful to both humans and the environment. Utility Model Content
