Operation Principle
The HSS Multi-Stage Desulfurization and Dust Removal Unit is a new generation product developed by our company based on years of practical operation experience with desulfurization equipment. It addresses the issues present in wet desulfurization processes and aims to enhance desulfurization efficiency. While maintaining the advantages of being made from granite, such as resistance to acid, alkali, and abrasion, this product also boasts the following notable features:
The desulfurization of waste gas is achieved through multi-stage separation and dehydration. The first stage utilizes a uniquely designed rotary washing device, which is set at the inlet of the multi-stage separator to facilitate the upward movement of waste gas from bottom to top. As the waste gas enters the washing tower from the bottom, the liquid breaks down to form water droplets and mist, which mix with the gas and rise. This process increases the weight and adhesion of the dust, allowing sulfur dioxide gas to have sufficient contact with the alkaline washing solution for neutralization.
2. The cylinder design incorporates an internal vertical cylinder and a unique upper rotating multi-disc inertial separator, which features a structure that is both individually independent and closely connected. This not only causes the liquid droplets separated from the gas to disperse again on the round basin's fluid surface, but also converts the rotating gas flow into a multi-port rotating separation. It enables the gas to disperse and combine with the liquid on the multi-directional guide plates, while also effectively dispersing secondary liquid droplets in the gas. The desulfurization efficiency is ≥80%, ensuring the continuous and reliable operation of the HSS equipment.
3. The working area, composed of the inner cylinder assembly, includes a circular dewatering cylinder. After entering the lower part of the working area, the material undergoes washing, a mixture of water and vapor rises, multiple centrifugal separation to separate the gas-liquid, and the generation and mixing of droplets again. The separated gas containing a small amount of liquid enters the dewatering space, where it is more reliably separated and dewatered through a low-speed upward flow centrifugal separation. This process achieves a gas emission moisture content of less than 8%.
The tower is constructed entirely of granite material. This ensures that the tower is not only aesthetically pleasing and sturdy, but also corrosion-resistant, wear-resistant, and leak-proof.
