What is the flow path of the gas in the air tank of the pulse jet dust collector’s injection system?
Thread Content
I recently looked at the structure of bag dust collectors and saw the diagram of the air tank shown below. Does the gas in this diagram enter the bags through those vertical tubes at the bottom? What is the direction of the gas flow? What about the internal structure of the air pocket? I would like to ask everyone for advice
As shown in the image, the flow of gas within the air tank of the bag filter’s blowing system is roughly as follows: 1. The gas enters the air tank through the inlet pipeline； 2. The air pocket contains multiple small holes or nozzles that spray compressed air onto the vertical injection tube ； 3. The gas from the blowing tube is ejected upward along the pipe, pushing the dust inside the pipe onto the cloth bag ； 4. The end of the blowing tube is open, allowing the dust deposited at the bottom of the bag to be blown out and fall into the dust collection hopper. Regarding the internal structure of the air tank, it usually consists of a housing, a partition, and valves. After entering the air tank, compressed air first passes through a partition, and then, based on the set pressure and time parameters, valves are used to control the opening and closing of the spray nozzles, thereby allowing for precise control over the duration and intensity of the gas emission. This allows for effective cleaning of the bag filters, thereby improving dust removal efficiency. .
The dust collector purge air tank is a forgotten pressure vessel; many of such tanks have a volume of more than 30 liters, a nominal diameter of over 150 mm, and use compressed air as the working medium. As far as I know, no organization has carried out registration or inspection for these tanks, nor are there any regulatory authorities tasked with overseeing them. The flow of gas enters the air tank through the inlet for storage; release occurs when power is supplied to the corresponding pulse solenoid valve, after which the gas is discharged through the pipeline connected to that solenoid valve.
To be honest, it looks pretty awkward. It is recommended to check the drawings to see if there are any issues with the on-site installation. It is usually controlled by a PLC to operate the solenoid valve for air injection. I can’t figure out the installation location of this solenoid valve,,,,. For reference.
This is a submersible solenoid valve, with both the inlet and outlet located on the lower side along the same centerline.
Is this the way for import and export?
Excuse me, is this the way for import and export?
Is this kind of air leakage on his side like this?
