XDII Multi-Cyclone Dust Collector

Overview

The XD-II multi-cyclone dust collector is a high-efficiency dust collection device, achieving a collection efficiency of over 95%, with the collector body resistance below 900 Pa. This collector offers excellent load adaptability, maintaining a collection efficiency of over 94% at 70% load. The cyclone elements inside the collector are made of cast iron or ceramics, with a thickness greater than 6 mm, ensuring excellent wear resistance. It is an ideal piece of equipment for flue gas dust removal from industrial boilers and for other dust control applications.

Working Mechanism

When airflow undergoes rotational motion, dust particles within the airflow are separated from the gas stream due to centrifugal force. The technology that utilizes centrifugal force for dust removal is known as centrifugal dust collection technology, and the equipment used for this purpose is called a cyclone dust collector.

In a cyclone dust collector, dust-laden gas enters the device tangentially, and due to centrifugal force, dust particles are separated from the gas, thereby achieving flue gas purification. The airflow within the cyclone dust collector rotates through many cycles, and the linear velocity of the rotating airflow is also very high, so the centrifugal force exerted on particles in the rotating airflow is far greater than gravity. For small-diameter, high-resistance cyclone dust collectors, the centrifugal force can be up to 2500 times greater than gravity. For large-diameter, low-resistance cyclone dust collectors, the centrifugal force is still more than 5 times greater than gravity.

Main Components

The dust collector consists of cyclone bodies, a hopper, and a volute (or cover). The vibrating ash cleaning system comprises four parts: the inlet, outlet, ash discharge system, and electrical control system.

Handling Air Volume Range

10,000 ~ 2,000,000 m³/h, with outlet emission concentration below 50-10 mg/Nm³.

Applicable Industries

Purification of dust-laden gases and material recovery in the building materials, metallurgy, power, coal mill dust collection, and refractory materials industries.

Technical Innovation Points:

● Simple structure, no moving parts in the body, no special auxiliary equipment required, small footprint, and low manufacturing and installation costs.
● Easy operation and maintenance, moderate pressure loss, low power consumption, and low operating and maintenance costs; high separation efficiency for dust particles larger than 10 µm.
● Wide operational flexibility and stable performance, unaffected by the concentration or temperature of the dust-laden gas. No special requirements for the physical properties of the dust; additionally, different materials or various wear-resistant and heat-resistant linings can be selected based on specific production process requirements to extend service life.
● Air leakage at the ash discharge port of the dust hopper is strictly prohibited.
