Warehouse top single machine dust collector

The single machine dust collector on the top of the silo is a dust removal equipment used on the top of the silo. The single machine dust collector on the top of the warehouse is mainly used in the silos of mining, metallurgy, building materials, machinery, chemical industry, grain processing and other industrial and mining enterprises. And it is widely used as a dust removal equipment for filtering small, non fibrous dry dust in gases or recovering dry powder materials in the process flow.

Separate the floating dust particles in the silo through cloth bags and discharge clean air into the atmosphere to protect the environment.

A single machine dust collector on the top of a warehouse is generally composed of an induced draft fan, an upper box body, a connecting flange, and an electrical control cabinet. The upper box body has a dust removal bag and a dust removal skeleton inside. The dust removal bag and skeleton are installed on a flower board, which is the boundary between clean gas and dusty gas. Below the flower board are the dust removal bag and skeleton, and above the flower board are the spray pipe and pulse valve. Weld the flange together with the cement silo (or other powder container) as a support for the dust collector; Use bolts to seal and connect the upper box body with the welded flange as a whole; Seal the middle connection with sealant; When the screw machine feeds the powder machinery, the pressure inside the warehouse is lower than atmospheric pressure, so that air is supplied from the atmosphere to the warehouse to make the screw machine work normally within the applicable range.

Pulse jet cleaning of single machine dust collector on the top of the warehouse: When using high-speed jet airflow to pass through the high-quality filter bag, it blows towards the inside of the filter bag, forming an air wave, causing the filter bag to rapidly expand and vibrate from top to bottom, producing a powerful effect of dust removal. Pulse cleaning has a strong dust removal effect and a good dust removal effect, which can increase the filtering wind speed. It is currently the most effective way to clean dust.

working principle

The dusty gas enters the dust collector box through the air inlet, and small dust particles are trapped on the outer wall of the bag due to various effects of the bag. The purified gas is discharged through the air outlet of the box on the cloth bag. As the usage time increases, the amount of dust adsorbed on the surface of the bag increases, the breathability of the bag decreases, and the resistance of the dust collector continues to increase. To control the resistance of the dust collector within a limited range, a pulse controller sends a signal to sequentially open the electromagnetic pulse valve, causing the compressed air in the air bag to be sprayed from each nozzle of the blowing tube to the corresponding Venturi tube (called primary air), and inducing the surrounding air (called secondary air) with a derivative multiple of the primary air to enter the filter cartridge when the high-speed airflow passes through the Venturi tube, causing rapid expansion between the bags. Due to the impact of the reverse pulse airflow, the bags quickly disappear, and the bags shrink sharply, causing the dust accumulated on the outer wall of the bags to be trapped and the falling dust to enter the ash storage.

Precautions for using a single dust collector on the top of the warehouse:

1. The single machine dust collector on the top of the warehouse is not suitable for damp and corrosive gases, and should not handle exhaust gas or dust above 120 degrees Celsius for a long time. If high-temperature working conditions need to be handled, a customized high-temperature dust removal bag is required.

2. If there are any abnormal phenomena during the opening, stopping, and operation of the single machine dust collector on the top of the warehouse, it should be stopped immediately for inspection and repair.

3. To stop the machine, press the stop button and let the shaking mechanism work for several seconds. Do not directly cut off the power.
