Sinter plant dedusting system design
Sinter plant dedusting system plays a very important role in environmental protection. The design of sinter plant dedusting system is of great significance to improve the combustion utilization efficiency of sintering machine and reduce dust emission. This article will discuss the design of the dedusting system in sinter plant.
The sintering process is a dust-intensive process which transforms iron ore, limestone and other materials into a porous material suitable for use in the blast furnace process. The sintering process is a large source of dust emission, making it necessary to install an effective scrubbing and dedusting system to clean the air before release. The sinter plant dedusting system design includes four main components: dust scrubbers, dust collecting system, stack and fans.
The dust scrubber is used to remove particulate matter from the sintering process exhaust gas before it is vented to the atmosphere. There are a variety of different scrubber designs available, but the type typically used in sinter plants is the venturi scrubber. The venturi scrubber uses a combination of pressure and diffusion to capture and separate particulate matter from the exhaust gas. This is then collected in a sump located at the base of the scrubber and removed from the system.
The dust collecting system is responsible for collecting the particulate matter that is extracted from the scrubbing process and conveying it away from the sinter plant. There are a variety of different collecting systems available, but the most commonly used system in sinter plant dedusting systems is the cyclone collector. The cyclone collector uses centrifugal force to separate particulate matter from the gas stream before it is vented to atmosphere. The trickling filter is another dust collecting system that can be used in sinter plants, although it is not as efficient at collecting dust as the cyclone collector.
The stack is the area of the sinter plant dedusting system that releases the cleaned air back into the atmosphere. The stack should be designed to have a large surface area in order to reduce the velocity of the exhaust gas and allow time for the particulate matter to settle out of the exhaust gas stream. The stack should also be designed to ensure proper and efficient release of the exhaust gas into the atmosphere.
Finally, the fans are used to create the air flow needed for the scrubbing and dust collecting processes. There are a number of different fan designs available, but generally the centrifugal fan is used in sinter plant dedusting systems. The centrifugal fan is capable of generating a high pressure, low volume air flow which is ideal for scrubbing and dust collecting processes.
In conclusion, the design of sinter plant dedusting system is very important to reduce dust emission and improve the combustion utilization efficiency of sintering machines. The design must include a dust scrubber, dust collecting system, stack and fans in order to be effective. The success of the system will ultimately depend on how well these components are designed and installed in the sinter plant.
