DMC type pulse single machine dust collector

The DMC type pulse single machine dust collector belongs to a type of pulse dust collector. The pulse bag filter adopts the technology of high-pressure (0.5-0.7Mpa) high flow pulse valve to blow and clean the dust filter bag one by one. It has the advantages of high dust cleaning kinetic energy, low air leakage rate, long dust cleaning cycle, small volume, light weight, simple and compact structure, easy installation, and convenient maintenance (external filter type). It is suitable for flue gas dust removal in the building materials, machinery, metallurgy, building materials, machinery, and chemical industries.

The DMC pulse single machine dust collector belongs to the mechanical shaking type dust collector, which can collect and separate dust and particles in the airflow. It mainly uses mechanical vibration to clean the dust. This pulse jet single machine dust collector can be equipped with shot blasting machines, as well as equipment with high dust concentration such as sand machines, crushers, sand screening machines, and sand mixers for dust removal. Practice has proven that it operates stably, has low noise, good dust removal effect, and is easy to operate and maintain. The pulse jet single machine dust collector is mainly composed of an outer shell, a high-pressure fan, a filter bag, a dust collection drawer, an abdominal chamber, an inlet duct, an air duct, and a circuit device.

The structure of DMC type pulse single machine dust collector mainly consists of a filter chamber, filter bag, clean air chamber, ash hopper, ash unloading device, spray cleaning device, and electric control system. There are six or seven series of single pulse dust collectors, and each specification is divided into two types: standard ash hopper type (Type A) and open flange type (Type B without ash hopper).

The basic structural composition of DMC type pulse single machine dust collector

The basic structure of DMC type pulse single machine dust collector consists of three parts: fan, filter, and dust collector. Each component is installed in a vertical frame, with a steel plate shell, baked paint for rust prevention, stable operation, and easy use. The DMC type pulse single machine dust collector fan adopts a centrifugal fan with high air volume and pressure, and adopts noise reduction measures, resulting in low noise. The filter adopts a flat bag group, and each bag is equipped with a spring steel wire mesh for good filtering effect. The dust cleaning mechanism uses an electric motor to drive the eccentric wheel and connecting rod to make the bag shake and clean the dust adhering to the surface of the filter bag. This pulse jet single machine dust collector is equipped with an inspection door for easy maintenance and bag replacement.

The working principle of DMC type pulse single machine dust collector: The dusty gas enters the ash hopper through the inlet or enters the filter bag chamber through an open flange. The dusty gas is filtered by the dust collector filter bag into purified gas and enters the clean air chamber. It is then discharged by the fan through the exhaust port of the clean air chamber. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the bag filter to continuously rise. In order to ensure that the equipment resistance does not exceed 1200Pa and the bag filter can continue to work, the dust on the filter bag needs to be removed regularly. Dust cleaning is carried out by the PLC program controller starting the pulse valve in a timed sequence, so that the compressed air (0.5-0.7Mpa) inside the air bag is sprayed out from the blowing tube (called primary air) through the Venturi tube, inducing several times the surrounding air (called secondary air) into the filter bag, causing the filter bag to expand instantly, and shaking off the dust with the reverse force of the airflow, achieving the purpose of dust cleaning.
