Patent: A Chromium Powder Spray Drying Tower for Chromium Waste Recycling

Chromium waste refers to waste materials such as chromium containing wastewater and waste residue in industrial production. Chromium wastewater is a common type of waste in the chromate industry, and its hazards mainly lie in its toxicity and environmental impact. If discharged directly into the environment without treatment, it can pose a threat to the aquatic ecological environment and human health. Chromium containing wastewater is also a common type of waste in the electroplating industry. Due to the presence of other harmful substances in electroplating wastewater, it is more difficult to treat and requires stricter treatment methods. In addition, the waste generated in the chromate industry usually contains chromium elements, and the treatment of waste is usually classified first, and then different treatment methods are adopted according to different materials. For chromium containing waste residue, methods such as roasting and leaching are usually used to separate chromium elements from the waste residue, achieving the goal of resource utilization.

In summary, chromium containing waste poses potential hazards to both the environment and human health, therefore, proper disposal methods must be adopted. Today, we will share a mechanical device called chromium powder spray drying tower that can be used for the renewable utilization of chromium waste. This device can reduce environmental pollution and achieve the recycling of chromium resources.

The chromium powder spray drying tower mainly includes a spray drying mechanism; It also includes feeding mechanism, feeding mechanism, waste heat reuse mechanism, filtering mechanism, locking mechanism, and installation mechanism. Among them, the feeding mechanism and feeding mechanism are installed at the top of the spray drying chamber, the waste heat reuse mechanism is installed on the spray drying mechanism, the filtering mechanism is installed at the end of the waste heat reuse mechanism, and the locking mechanism and installation mechanism are installed on the filtering mechanism.

This utility model patent design improves the efficiency and quality of spray drying, filters exhaust gas, and facilitates the collection of filtered chromium powder. The collected chromium powder can be further reused through purification, impurity removal, and other processes.
