The Sulfur Removal Method with Rock Bags
Rock bag desulfurization (RBD), also known as scrubber desulfurization, is a cost-effective method to remove sulfur emissions. The method can be applied to dozens and hundreds of smokestacks, and is widely used in many countries. Rock bag desulfurization system is not only a kind of simple, operation - and maintenance-free, fully automatic flue gas desulfurization equipment, but also an effective desulfurization process.
The process starts by burning fuel fuel. The flue gases that come from burning contain sulfur dioxide (SO2) and other pollutants. The flue gases are then passed through a series of pipes and into a chamber which contains rock bags with a calcium oxide-based mixture. The mixture then reacts with the sulfur dioxide to form calcium sulfite, which can be removed from the flue gases from the exhaust fan.
The rock bags are made from an inert material that can withstand high temperatures and last for many years. Calcium oxide is the key component of the material, so it needs to be chemically resistant in order to stay active for long periods of time.
The rock bags are loaded with a certain amount of the calcium oxide-based mixture depending on the type of the exhaust gases to be treated. This mixture is then loaded into a system of pipes that allows the flue gases to be forced through the rock bags one at a time. When the flue gases are forced through the rock bags, they react with the calcium oxide-based mixture and form calcium sulfite.
The position and size of the rock bags is critical in order to optimize the efficiency of the RBD system. It is important to ensure that the mixture is evenly distributed throughout the rock bags in order to ensure a more uniform reaction with the sulfur dioxide.
The calcium sulfite needs to be removed from the flue gases before they are sent to the atmosphere. This is done by using an exhaust fan to reduce the pressure on the rocks bags, which forces the calcium sulfite-containing particles to be collected on the other side of the chamber. This particulate matter can either be collected in sacks or liquidated, depending on the type of collector used and the concentration of sulfur dioxide in the exhaust gases.
The rock bags can also be reused after a certain period of time, or regeneration process is conducted. This process involves removing the calcium oxide-based from the rock bags and cooling it down before reloading it with a new mixture of calcium oxide. This process helps to increase the efficiency of the rock bags and reduce the cost of operating the desulfurization system.
The sulfur removal method with rock bags is an effective, cost-efficient way to reduce sulfur emissions. The method is simple to install and operate, and requires minimal maintenance. The rock bags are also reusable, which reduces the cost of operation even further. Additionally, the method is effective at removing sulfur dioxide from the flue gases, and can be adapted to various types of exhaust gases.
