Detailed introduction of / series long bag offline pulse dust collector / series long bag offline pulse dust collector is an advanced pulse bag dust collector specially developed to meet the needs of large air volume purification based on the injection pulse dust removal technology. The jet pulse dust collector not only has the characteristics of strong dust cleaning ability, high dust removal efficiency, and low emission concentration, but also has the characteristics of stability and reliability, low air consumption, and small footprint. It is especially suitable for processing flue gas with large air volume.
Structural features of the long bag offline pulse dust collector
The long bag offline pulse dust collector mainly consists of a box, a ash hopper, an air inlet equalizer duct, an outlet air duct, a bracket, a filter bag and a blowing device , ash discharge device and other components. It uses a thin-plate poppet valve to achieve three offline states, with advanced dust cleaning technology and reliable operation.
The long-bag low-pressure pulse bag dust collector's reasonably designed air inlet equalization pipe and ash hopper diversion technology solve the phenomenon of uneven air flow in each compartment that is often caused by general bag dust collectors.
The bag structure of long bag low-pressure pulse bag dust collector has various structural forms (octagonal, circular, etc.) according to different working conditions. Replacing filter bags is quick and easy.
The upper end of the filter bag of the long bag low-pressure pulse bag dust collector adopts the form of a spring expansion ring. It is sealed and repaired. The standard length of the bag cage for replacement is 100, and it can be increased according to needs.
The service life of the diaphragm, the wearing part of the electromagnetic pulse valve of the long bag low-pressure pulse bag dust collector, is more than 10,000 times. The dust collector can be controlled by an advanced programmable controller, which has three control modes: differential pressure, timing, and manual. It can realize comprehensive system control of the dust collector offline network, pulse valve, ash discharge room, etc.
Performance parameters of long bag offline pulse dust collector
Dust-laden air enters the ash hopper of each chamber from the air inlet equalization pipe of the long bag low pressure pulse bag dust collector and is guided by the ash hopper diversion device Under the filter, large particles of dust are separated and fall directly into the ash hopper, while finer dust is adsorbed on the outer surface of the filter bag. Clean gas enters the upper box through the filter bag and is discharged into the atmosphere through each offline valve and exhaust pipe. As filtration proceeds, more dust accumulates on the filter bag. When the equipment resistance reaches the limited resistance value, the dust cleaning control device automatically closes the offline valve of the first chamber according to the differential pressure setting value or the cleaning time setting value. Then, open the electronically controlled pulse valve according to the set procedure, stop the air and blow, causing the pressure inside the filter bag to increase suddenly, and shake the dust on the filter bag into the ash hopper, and then discharge it from the ash discharge mechanism.
The long-bag low-pressure pulse bag dust collector is a large-scale dust removal equipment with large air volume, good dust cleaning effect, high dust removal efficiency, reliable operation, easy maintenance, and small footprint. It is used in dust control and material recovery in metallurgy, building materials, electric power, chemical industry, carbon black, asphalt concrete mixing, boiler and other industries.
