Cyclone filters are devices often used in the environmental field. This article summarizes the mechanism, applications, features and types of cyclone filters.
What is a cyclone filter?Equipment for separating powdered solids mixed in gases or liquidsIt is. Sometimes simply called a "cyclone".
Cyclone filters separate powdered solids by rotating the filtrate at high speed and generating centrifugal force. Despite its simple structure, the cyclone filter has high separation efficiency and excellent resistance to abrasion and corrosion.
How to separate powder in a cyclone filter,Centrifugal forceIt is. It is almost the same principle as a centrifuge, so it may be easier to understand if you think of a centrifuge. The mechanism is as follows.
When a gas or liquid is poured into a conical container at high speed, the gas or liquid begins to swirl inside the container. At this time, centrifugal force pushes the powdered solids outward (toward the inner vessel wall). The removed materials such as concentrated dirty liquid and collected dust are then discharged from the bottom opening.
From the top, the cleaned gas or liquid is discharged. This is how the cyclone filter separates powders.
Recommended products by type from companies that offer filtration tests or loaner equipment to check if the filtration equipment matches your company's issues prior to introduction. Companies facing filtration challenges in the grinding process are encouraged to refer to this section.
Applications of cyclone filters include
Cyclone filters are used not only to remove suspended solids, sludge, contaminants, and dust, but also to separate powders according to particle size and collect only powders with small particle sizes.
There are different ways to classify cyclone filters.When focusing on the filtration object, there are two types: "liquid cyclone" used when the filtration object is a liquid, and "dry cyclone (gas cyclone)" used when the filtration object is a gas.The following is a list of the most common problems with the
Classification by cyclone inlet shape includes "tangential inlet type," "semi-circumferential spiral type," and "full circumferential spiral type," with the full circumferential spiral type having superior collection performance.
Classification by filtrate inflow direction includes "tangential inflow type" and "axial flow type," while classification by filtrate outflow direction includes "reversal type" and "straight flow type.
In terms of the number of cyclone filters, there are two types: "single cyclone," which separates with a single cyclone, and "multi-cyclone," which separates with multiple cyclones side by side.
Single cyclone" is reasonably priced, but has lower separation efficiency than "multi-cyclone". Multi-cyclone" has higher separation efficiency but also higher pressure drop.
A cyclone filter is a device for separating powdered solids mixed in gas or liquid, and its principle is based on centrifugal force. Often used in the environmental field, they are employed to remove suspended solids, sludge, and dust. The particle size that can be collected and the processing capacity per unit time vary greatly depending on the specifications, so it is important to select the appropriate device according to the characteristics, purpose, and application of the material to be filtered.
Coolant filtration equipment is used to filter sludge generated from equipment. There are a variety of products available depending on the intended use, so it is important to determine "whether the coolant filtration equipment is suitable for the purpose" and "whether the equipment is suited to the characteristics of sludge.
