High salt wastewater dryer

High-salt wastewater refers to wastewater with a total salt content of at least 1%. It mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals, and radioactive substances). The production of salty wastewater is extensive, and the amount of water is increasing year by year. It is crucial to remove the impact of organic pollutants in salty wastewater on the environment. Biological treatment is used. High concentrations of salt substances have an inhibitory effect on microorganisms. Physical and chemical treatment requires large investments and high operating costs, and it is difficult to achieve the expected purification effect.

Product advantages
1. Heat is transferred from the inner wall of the cylinder to the outer wall of the cylinder, and then passes through the material film. It has high thermal efficiency and can be operated continuously. Therefore, it is widely used in the drying of liquid materials or strip materials and is more suitable for paste and viscous materials.
2. Based on the existing equipment and technology, a new process for drying high-salt mother liquor wastewater has been developed. It is a drum scraper dryer that is particularly suitable for drying high-salt mother liquor wastewater.
3. The generated waste gas can be cooled.

Product Features

1. With steam or heat transfer oil as a heat source, the heating area is large, the thermal efficiency is high, and the heating is uniform.

2. The drying rate is high, and the heat and mass transfer process of the wet material film on the drum wall is consistent from the inside to the outside, and the temperature gradient is large so that the surface of the material film maintains a high evaporation intensity.

3. High operational flexibility and wide practicality: the concentration of the feed, the thickness of the coating film, the temperature of the heating medium, the rotation speed of the drum, etc. can all change the drying efficiency of the drum dryer.

4. Short drying time: The material drying cycle only takes 10 to 300 seconds, which is suitable for heat-sensitive materials, easy to operate, and convenient to maintain.
