Problems in desulfurization, dust removal, and environmental protection

1. The flower board should be flat, bright, and free from uneven defects such as bending and concavity. Its flatness error should not exceed 4/1000 of the length of the flower board.

2. The periphery of the flower board hole should be smooth and free of burrs, and the aperture should be+20mm. If the elastic expansion ring is used for fixation, the size of the aperture of the flower board in public service can be appropriately relaxed to+0.30 mm.

3. After processing the aperture of the flower board, the error between the practical orientation and the planned orientation should be less than 1.5 mm.

4. The flower board should be coated after sandblasting, dust removal, and rust removal to prevent rust and corrosion.

5. For large pulse dust collectors, 6mm thick steel plates should be selected and reinforced with good stiffness to prevent deformation under stress.

The flower board of desulfurization, dust removal, and environmental protection dust collector plays an important role. If not handled properly, the filter bag is often worn, which can shorten the service life of the filter bag.

Bag dust collectors may also encounter problems during operation. Now let's analyze these problems to find ways to solve or prevent them. Bag dust collectors play an important role in various manufacturers' equipment with severe dust, and have attracted more attention from enterprises due to their advanced technology, reliable operation, and easy protection. But there is nothing in the world, and bag filters can also present problems during operation. Now let's analyze these problems here to find ways to solve or prevent them.

1. Environmental issues:

Most pulse bag filters use an upper suction bag structure, which requires a certain height in the factory building. In production, the use of dust collectors is often constrained by inadequate factory height.

Environmental protection treatment methods for desulfurization and dust removal:

(1) Choose the method of lowering the height of the ash hopper and use a double ash hopper structure. However, this method requires one screw conveyor and a feeder, with a slight increase in operating costs.

(2) The multi-level bag cage method can be used, which will increase the workload when loading and unloading bags.

(3) The roof can be pierced through, and the pulse dust collector can be placed in the open air. Based on the flue gas conditions, it is determined whether humidification is necessary, and the rain protection of electrical equipment should also be considered.

2. Air flow issues:

The corner of the filter chamber near the air outlet shows vortex or airflow disturbance, which makes the bottom of the filter bag (about 20cm) prone to wear and tear.

Reason for environmental protection issues in desulfurization and dust removal: The planning did not fully consider the adoption of reasonable airflow dispersion methods.

3. Temperature issues:

Sometimes the flue gas temperature is relatively high, the lifespan of the filter bag decreases, and sometimes there is a phenomenon of burning through the cloth bag.
