Technology for extracting ammonium chloride from industrial wastewater containing ammonium chloride
1. Project Introduction
This technology is mainly used for industrial wastewater containing ammonium chloride comprehensive management. At present, ammonium chloride-containing industrial wastewater in my country pollutes the environment very seriously, including inorganic chemicals, organic chemicals, rare earth element plants, etc., and industrial wastewater treatment is a big problem. Generally, the sewage treatment projects of enterprises are at a slight loss or even. Good project. This technology uses closed-circuit circulation of water. The evaporated water is cooled by the cooling water tower and then recycled. The discharged wastewater is clean condensed water and meets the discharge standards. Its "low-temperature, multi-effect, heat pump evaporation and normal temperature crystallization" process and advanced falling film evaporation equipment have made the technology world-leading and has been awarded an invention patent.
II. Market Prospects
This technology mainly extracts ammonium chloride from industrial wastewater containing ammonium chloride, which not only solves the environmental pollution caused by industrial wastewater. At present, it has been transferred to Hebei, Henan, Shandong, Zhejiang, Jiangsu, Fujian, Shandong, Shenzhen, and other provinces and cities. The social and economic benefits are very obvious. The technology is mature and reliable. In short, the market for ammonium chloride is relatively broad and has good prospects.
3. Main equipment and investment
We use three-effect, heat pump, vacuum, and evaporation processes. The normal temperature crystallization process can meet the requirements of energy conservation and environmental protection. The evaporator is made of titanium. The life span is 10 years, which reduces equipment investment relatively. If the annual production capacity is 10,000 tons of ammonium chloride, the investment will be nearly 10 million yuan.
IV. Benefit Analysis
Ammonium chloride is an inorganic salt and is mainly used in agricultural fertilizers, metal welding, electroplating, tanning, dry batteries, food, medicine and other sectors. In particular, large amounts of chemical fertilizers are used in agriculture. According to the survey, ammonium chloride is very popular. The price of agricultural ammonium chloride is more than 500 yuan/ton, while the price in Jiangnan is more than 6 million yuan/ton; the cost price is about 380 yuan/ton. If the annual output of ammonium chloride is 10,000 tons, the annual economic benefit will be 1.2 million yuan. If it is refined to industrial grade, its price is 1,500 yuan/ton. The cost per ton is around 700 yuan. If it is refined into food grade or pharmaceutical grade ammonium chloride, the sales price will be much higher than the price of industrial grade, and it can also be exported to earn foreign exchange. The economic benefits will be higher.
