Design of collection method for melting furnace baghouse dust collector

Baghouse dust collector collection method design

The characteristics of the exhaust gas of the aluminum melting furnace are:

The dust is fine and light;

The exhaust gas temperature is high (about 200 ° C);

The dust concentration fluctuation range is large;

The fuel is natural gas, so the humidity is large and has certain corrosiveness.

Therefore, high-efficiency dust collectors must be used for the treatment of fine dust, baghouse dust collectors are a more practical choice for all dust removal technologies.

Baghouse dust collector choosing

The reasonable choosing of the melting furnace baghouse dust collector is the key to affect the life of the dust collector filter bag.

If the choosed dust collector capacity is too small, the filtration speed of the filter material will be increased, thereby greatly reducing the service life of the filter bag.

If the capacity is too large, it will increase investment and cause unnecessary waste.

When choosing the model, we fully consider a series of factors such as the nature of the flue gas and the concentration of dust.

According to the requirements of the filter material, the filtration wind speed is determined to be <1m/min, and the rising speed of the airflow and the wind speed of the inlet and outlet valves are reasonably designed.

Main parts and its working

Aluminum melting furnace baghouse dust collector is composed of a cooling device, dust removing shell, filter bag, dust hopper, dust discharging device, bracket and a pulse cleaning system etc.

When the dust-containing gas enters the cooling device from the air inlet, cool the gas to the temperature that the bag can bear and go into the filter bag.

First, it hits the inclined baffle in the middle of the air inlet, and the airflow turns into the dust hopper, and the airflow speed becomes slower, due to gravity setting, the coarse particles of dust in the gas  fall into the dust bucket directly, which plays the role of Pre-collection. The airflow entering the dust bucket is then folded upwards.

After passing through the filter bag with the metal frame inside, the dust is caught on the outer surface of the filter bag, and the purified gas enters the clean room at the upper part of the filter bag chamber, and is collected and discharged to the outlet pipe.
