Mine bag dust collector

Precautions for mine dust collector
d=,
) The injection of the dust cleaning device adopts a tubular center injection.
) The injection pressure includes low-pressure injection, with a pressure lower than that, and high-pressure injection, with a pressure higher than. The high-pressure air source has greater kinetic energy and consumes less air, while the low-pressure air source has smaller kinetic energy and consumes more air. No matter the pressure of the pulse injection air source is high or low, the purpose is to achieve thorough dust cleaning, and the required cleaning energy is the same.
) The injection soot cleaning mechanism is divided into combinations without a drainage nozzle and no venturi, with a drainage nozzle without a venturi, and with a drainage nozzle and a venturi.
) Pulse injection dust cleaning can be divided into online dust cleaning and offline dust cleaning. By adjusting the dust collector parameters, online and offline cleaning can achieve basically the same cleaning effect.
The mine dust collector has the advantages of simple structure, low investment cost, simple and reliable operation, and low technical requirements for management and maintenance. The mine dust collector has the characteristics of small resistance, high dust removal efficiency, large air volume, stable performance, small footprint, simple structure, practicality and low price. After the dust-containing gas enters through the air inlet on the upper part of the ash hopper, under the action of the windshield, the airflow flows upward, the flow rate decreases, and some large particles of dust are separated and fall into the ash hopper due to the effect of inertial force.
Working principle of mine dust collector
When the flue gas containing dust enters the middle and lower boxes from the air inlet of the dust collector, the dust is adsorbed on the dust removal filter bag, and the gas passes through the filter bag and passes through the venturi The inner tube enters the upper box and is discharged from the air outlet. As dust accumulates on the filter bag, the pressure loss of the filter bag gradually increases. This pressure loss is fed back to the controller by the pressure gauge. The controller receives and issues instructions, triggering each pulse solenoid valve in sequence, so that the gas in the air bag is instantly ejected from each hole of the blow tube, and is injected into the corresponding filter bag through the Venturi tube. The filter bag is instantly moved by the air flow. It expands rapidly under the reaction, causing the dust accumulated on the surface of the filter bag to fall off, and the filter bag can be regenerated and reused.
