What is an ammonium chloride evaporator? What is an ammonium chloride evaporator? What is the use of ammonium chloride evaporator? Today, Kang Jinghui Xiaobian and everyone talk about the ammonium chloride evaporator.
First, what is an ammonium chloride evaporator?
What is an ammonium chloride evaporator? As the name suggests, ammonium chloride evaporators are evaporator equipment used to treat industrial wastewater containing ammonium chloride.
Industrial wastewater containing ammonium chloride produced in the process of producing aminoacetic acid, which contains methanol, formaldehyde, chloroacetic acid, aminoacetic acid and other organic substances, with many varieties, high content and difficult treatment.
For ammonium chloride industrial wastewater, the current common treatment method is mainly to use evaporation concentration, so that a part of the material crystallization, separation, in the evaporation concentration process to consume a lot of steam and cooling water, high operating costs, energy consumption.
Therefore, many enterprises are seeking and choosing suitable ammonium chloride wastewater treatment equipment, ammonium chloride industrial wastewater treatment process, in order to meet the requirements of environmental protection, but also to reduce environmental protection operating costs, for enterprises to increase economic and social benefits.
Second, ammonium chloride characteristics
Ammonium chloride (Ammonium chloride), the pure product is a white powder or a slightly yellowish square, octahedral crystal, the taste is salty and cool and slightly bitter, from the surface looks very similar to table salt.
Relative density 1.527. Soluble in water, also soluble in liquid ammonia and glycerin, slightly soluble in alcohols, insoluble in acetone and ether. When heated to 100 °C, it begins to volatilize significantly, dissociates into ammonia and hydrogen chloride at 337.8 °C, and recombines after cold to form a very small particle of ammonium chloride and appears as a white thick fog, which is not easy to sink and is not easy to dissolve in water. Heat to 350 °C sublimation, boiling point 520 °C.
Hygroscopicity is small, but when the product contains sodium chloride, sodium sulfate or is packaged under sufficient drying, it will lead to increased hygroscopicity. The aqueous solution is weakly acidic and increases when heated. It is corrosive to ferrous metals and other metals, especially to copper, and has no corrosive effect on pig iron.
Third, ammonium chloride evaporator selection
Kang Jinghui designed for the characteristics of ammonium chloride wastewater, ammonium chloride evaporator, according to the treatment capacity of ammonium chloride, material characteristics and the owner site for design, designed with ammonium chloride multi-effect evaporator, ammonium chloride MVR evaporator, using different evaporation processes to treat ammonium chloride wastewater.
