In many fields such as industrial production and environmental protection, operations such as solid-liquid separation and solid-gas separation are crucial. Both tubular settlers and traditional equipment play a role in these processes, but there are differences between the two in many aspects. The following is a detailed comparison:
Structural design
Tubular settler
It is a shallow sedimentation device composed of small plastic tube bundles of various geometric shapes. This structural design gives it a larger sedimentation area and higher sedimentation efficiency per unit volume. The design of small plastic tube bundles can increase the flow path of the fluid, giving particles more opportunities to collide with the tube wall and settle, thereby improving the separation effect.
Traditional equipment
Different types of traditional sedimentation equipment have different structures. For example, some traditional sedimentation tanks are simple large pools that rely on gravity to allow particles to settle naturally. The structure is relatively simple but occupies a large area. There are also some traditional filtration equipment that separates through components such as filters. The structure is relatively complex, and the filter needs to be replaced and cleaned regularly.
Separation efficiency
Tubular settler
Due to its unique tube bundle structure, it can provide a larger settling area, and the settling path of particles in the tube bundle is more complicated, which increases the chance of particle collision and settling, so the separation efficiency is higher. Especially for the separation of some fine particles, the tubular settler can achieve better results and can achieve effective separation of solid-liquid or solid-gas in a shorter time.
Traditional equipment
Traditional gravity sedimentation equipment, such as sedimentation tanks, has low separation efficiency, takes a long time for particles to settle to the bottom, and has poor separation effect for fine particles. Although some traditional filtering equipment can improve the separation efficiency to a certain extent, it is prone to clogging problems, which affects the normal operation and separation effect of the equipment.
Floor space
Tubular settler
The structure of the tubular settler is compact and the floor space is relatively small. By increasing the number of tube bundles and rationally designing the arrangement of the tube bundles, a larger settling area is achieved in a smaller space, which is suitable for use in places with limited space.
Traditional equipment
Like traditional sedimentation tanks, in order to achieve a better separation effect, a larger settling area is required, so the floor space is larger. This is a major limiting factor for some companies with limited land resources.
Scope of application
Tubular settler
It is suitable for treating liquids or gases containing a large number of fine particles. In the fields of chemical, petroleum, environmental protection, etc., it has a good effect on the treatment of some difficult-to-treat wastewater and waste gas. For example, in the upgrading and transformation of urban sewage treatment plants, tubular settlers can effectively remove suspended matter and some organic matter in sewage.
Traditional equipment
Different types of traditional equipment have different scopes of application. Gravity sedimentation equipment is suitable for treating materials with large particles and high concentrations; filtration equipment is suitable for situations with high requirements for separation accuracy but relatively small processing volume. However, for some materials containing a large number of fine particles, the treatment effect of traditional equipment may not be ideal.
Maintenance cost
Tubular settler
In general, the maintenance of tubular settlers is relatively simple. Its structure is relatively simple, without complex moving parts, which reduces the probability of failure. Moreover, the cleaning of the tube bundle is relatively easy, which can be carried out by backwashing and other methods, reducing maintenance costs.
Traditional equipment
Traditional filtration equipment requires regular replacement of components such as filters, which increases maintenance costs. Some large traditional sedimentation equipment, such as sedimentation tanks, require regular cleaning of the sediment at the bottom, which requires a lot of maintenance work.
