Air Pollution Control Equipment Cyclone Separation Dust Filter

Product Specification

Introduction of cyclone separator

The main function of the cyclone separator equipment is to remove the solid particles and droplets carried in the conveyed gas as far as possible, to achieve gas-solid-liquid separation, to ensure the normal operation of the pipeline and equipment, in the west-east gas transmission project, the cyclone separator is a more important equipment. Industrial applications of cyclones generally fall into four broad categories: control of air pollution, process equipment, as pre-separator units, and removal of liquid cargoes from gases. As a process equipment, it is also often used in conjunction with other drying, cooling, and grinding systems. It can also be used as a receiver for material products in pneu- matic conveying systems. It has the characteristics of simple structure, convenient operation, low price and high efficiency.

Structure design of cyclone separator 

The cyclone separator adopts vertical cylinder structure, which is divided into liquid collection area, cyclone separation area and purification chamber area along the axial direction. The inner cyclonic component is evenly arranged in the circular direction and fixed through the upper and lower tube plates; The equipment adopts skirt support, and the head adopts high pressure resistant oval head.

Matching flanges, bolts, gaskets, etc. are provided at the pipe ports of the equipment.

Generally, the gas inlet design is divided into three forms:

a) Upper intake air

b) Central intake

c) Lower intake

Cyclone separator adopts integral vertical structure, small size and light weight. The vertical layout of the cyclone tube is divided into three independent studios by two horizontal partitions. For the convenience of internal inspection, each studio is provided with a separate individual hole or hand hole. The cyclone separator comprises a shell part, an intake air, an outlet air, a vent, a separation unit, a manhole, a hand hole, an artificial dust cleaning and a valve-controlled dust outlet, a leg and other structures.

Engineering Application of cyclone separator

The cyclone separator is suitable for purifying non-viscous, non-fibrous dry dust larger than 1-3 microns. It is a kind of purification equipment with simple structure, easy operation, high temperature resistance, high equipment cost and high resistance (80 ~ 160 mm water column), and cyclone dust collector is the most widely used in purification equipment. The improved cyclone separator can replace the exhaust gas filtration equipment in some units.

Performance index of cyclone separator 

Separation accuracy

The separation effect of the cyclone separator: under the design pressure and gas volume conditions, the solid particles of ≥10μm can be removed. At the operating point, the separation efficiency is 99%, and at the operating point ±15%, the separation efficiency is 97%.

Pressure drop

Under normal working conditions, the pressure drop of a single cyclone separator at the working point is not more than 0.05MPa.

Service life

The design service life of the cyclone separator is not less than 20 years.

Characteristic of cyclone separator

The main characteristics of the cyclone separator are simple structure, high operating flexibility, high efficiency, convenient management and maintenance, low price, used to capture dust with a diameter of 5 ~ 10μm or more, widely used in the pharmaceutical industry, especially suitable for coarse dust particles, large dust concentration, high temperature and high pressure conditions, and often used as a fluidized bed reactor internal separation device. Or used as a pre-separator. However, its separation efficiency for fine dust particles (such as diameter <5μm) is low, and the fine powder separation efficiency can only reach 70% to 90%. In order to improve the dust removal efficiency and reduce the resistance, there have been many kinds of cyclone separators, such as spiral, spiral, bypass, diffusion, swirl and multi-tube.

The movement of gas and solid particles in a cyclone is very complex, with tangential, radial and axial velocities at any point in the cyclone, and varying with the radius of rotation. Proper gas velocity should be controlled in actual operation. The experiment shows that the gas velocity is too small and the separation efficiency is not high. However, the high gas velocity is easy to produce eddy current and backmixing phenomenon, which will also reduce the separation efficiency.

Applications of cyclone separator

Power Generation:

In coal-fired power plants, cyclone separators are used to remove fly ash and other particulates from the flue gas stream, protecting downstream equipment like electrostatic precipitators and fabric filters, and reducing emissions.

They are also used in biomass and waste-to-energy plants for similar particle removal purposes.

Mineral Processing:

Cyclone separators are extensively used in the mining, cement, and mineral processing industries to separate and recover valuable mineral particles.
