Single-tube cyclone dust collector

Single-tube cyclone dust collector is a mechanical dust removal device that uses the principle of centrifugal force to separate dust. It has the characteristics of simple structure and convenient maintenance, and is suitable for various industrial scenarios.

Industry scope

Boiler flue gas dust removal: especially for biomass boilers, etc.
Pre-dust removal in multi-stage dust removal systems: as the pre-stage of high-efficiency dust collectors to remove larger particles in advance.

Smelting, casting, sandblasting: to handle a large amount of dry, non-fibrous dust generated in these processes.

Building materials and refractory material production: such as dust removal in the production process of cement, lime, etc.

Food processing, pharmaceutical, and chemical industries: for dust collection in some processes.

Its core working principle is to make the dust-laden airflow rotate. With the help of centrifugal force, dust particles are separated from the airflow and collected on the wall of the device, and then fall into the ash hopper under the action of gravity. Under normal operating conditions, the centrifugal force acting on the particles can reach 5 - 2500 times the gravity, so its efficiency is significantly higher than that of the gravity settling chamber.

Main structure and characteristics

A single-tube cyclone dust collector usually consists of an air inlet pipe, an air outlet pipe, a cylindrical body, a conical body, and an ash hopper.

Characteristics

Simple structure and low cost: easy to manufacture, install, maintain and manage. Both equipment investment and operating costs are relatively low.

Efficient separation: it has a relatively high dust removal efficiency and a good collection effect on particles above 5μm. The efficiency usually reaches over 90%, and even up to 95%.
High-temperature resistance: by using special metals or ceramic materials, or coating a 10 - 20 mm wear-resistant and high-temperature-resistant lining on the inner wall, its temperature resistance can be significantly. Those made of ordinary carbon steel can be used for flue gas purification at 100°C, and those lined with refractory materials can even be used for flue gas treatment at up to 450°C or even 500°C.
Prevent secondary dust re-entrainment: many models have a reflecting screen at the bottom of the cone, which can effectively prevent the separated dust from being re-entrained by the secondary airflow.
Flexible treatment air volume range: the treatment air volume range of a single cylinder is relatively wide. Depending on the model, it can range from 500 cubic meters per hour to 50,000 cubic meters per hour, and multiple single cylinders can be combined to meet larger air volume requirements.

Performance parameters

Performance indicator Parameter range/description Source
Treatment air volume 500 - 50,000 m³/h (single cylinder)
Dust removal efficiency 90% - 99% (for particles above 5μm)
Equipment resistance Generally controlled at 500 - 2000 Pa, with a common value of 800 - 1000 Pa
Temperature resistance About 100°C for ordinary carbon steel; over 450°C for those lined with wear-resistant and high-temperature-resistant materials

Applicable dust Suitable for non-viscous and non-fibrous dry dust

Typical particle size collection Mainly used to remove particles above 5μm

With its simple structure, economical cost, convenient maintenance, and high-temperature resistance, the single-tube cyclone dust collector has a place in the field of industrial dust removal. It is especially suitable for handling dry dust with high concentration, coarse particles, and non-viscosity, and is often used as a pre-treatment unit or independently in occasions where the emission requirements are not extremely strict.
