Boiler dust collector

The boiler dust collector is fully prepared for the separation of ash materials after reaching the first stage of dust removal and desulfurization, and then enters the cylinder. The rapidly decreasing temperature of the flue gas continues to impact the lime water in the pool. The dust and SO2 in the flue gas react with the lime water in the pool to form sulfates, which sink to the bottom of the water under the action of inertia, gravity, adhesion, and cohesion to complete the second desulfurization process. The water droplets, water mist, and washed flue gas stirred up by the flue gas are lifted apart by the fan's gravity, allowing the flue gas and lime water to fully react. Then, the impeller dehydrator stops the separation of gas and water, and the water flows into the water pool through the drainage pipe, completing the third stage of dust removal and desulfurization of the flue gas. The purified gas is discharged into the water tank through the fan. Atmosphere.

Boiler dust collector is a commonly used supporting equipment in boilers and industries. Its function is to use boiler fuel to extinguish particulate smoke and dust in the exhaust gas, thereby significantly reducing the amount of smoke and dust emitted into the atmosphere. This is an important environmental protection equipment that mainly pollutes the environment and improves air quality.

Working principle of boiler dust collector:

The flue gas from the boiler dust collector enters the Venturi through the inlet duct and is horizontally sprayed into the throat inlet. Due to the high-speed movement of the flue gas, the sprayed water is melted into small water mist to wet the ash material in the flue gas. In this way, the ash material collides and condenses with the water droplets, especially the small diameter dust material can be dissolved by the water mist. Upon reaching dust removal and desulfurization, sufficient preparation is made for the separation of ash materials. Then, the rapidly cooling flue gas enters the cylinder and continues to impact the lime water in the pool. The dust and SO2 in the flue gas react with the lime water in the pool to form sulfates, which sink to the bottom of the water under the action of inertia, gravity, adhesion, and cohesion to complete the desulfurization process. The water droplets, water mist, and washed flue gas stirred up by the flue gas are lifted apart by the fan's gravity, allowing the flue gas and lime water to fully react. Then, the gas and water separation is stopped by the impeller dehydrator, and the water flows into the water tank through the discharge pipe, completing the third dust removal and desulfurization of the flue gas. The purified gas is discharged into the atmosphere through the fan.

Performance characteristics of boiler dust collector:

1. Adopting downward air intake has a pre dust collection effect on the dusty gas, preventing the dusty gas from directly flushing the bag, reducing the dust concentration of the dusty gas, and extending the life of the filter bag and pulse solenoid valve.

2. The sealing information of the dust collector is mainly based on actual reports.

3. The ash cleaning spray pipe adopts an elongated type to keep the pulse solenoid valve away from high-temperature flue gas and prevent damage to the valve disc of the pulse solenoid valve due to high temperature.

4. The filter bag adopts the actual report as the main filter bag, and the disposal of flue gas temperature is less than 250 ° C.

5. The filter bag mouth adopts an elastic expansion ring, which provides strong sealing.

6. The filter bag skeleton adopts a circular shape, which reduces the friction between the filter bag and the skeleton, prolongs the service life of the filter bag, and facilitates the unloading of the bag.

7. Adopting the upper bag extraction method, when changing bags, flip open the top cover door and extract the skeleton to replace the bag. The actual effect mainly depends on the operating conditions for bag replacement.

8. The dust cleaning control adopts timed control. According to the set time, every cleaning cycle, each row of filter bags is cleaned one by one.
