Comparison of the advantages and disadvantages of jet-type and swirl-type bag dust collectors
Thread Content
Both domestically and internationally, it is well known that the dust removal methods for low-pressure bag filters include rotary reverse blowing. The rotary type is primarily represented by Lurgi’s technology, and domestic companies such as Longjin and Sanrong use this technology, while the axial flow type is accepted by most manufacturers. Is that way better? Please ask an expert to discuss this.
No one is answering. We’re about to use the dust collector and are looking for information everywhere; could anyone with experience give us some advice?
Rotary injection can reduce the number of solenoid valves, but designing the rotating mechanism is challenging. I have only implemented linear injection so far; I am currently researching rotary injection, yet the issue of how to accurately position the injection using the rotating mechanism has not been resolved. In summary, I think row injection has higher reliability.
The technology is already mature; it’s still a cost issue. For rotary costs, imported parts are currently available at a slightly higher price. Technically, there’s no significant difference; in relatively larger units, the rotation is better. For large-scale units, rotary pulse valves are preferable; there are too many solenoid valves, which makes maintenance more complicated.
The pulse valves used are relatively large, and it seems that there aren’t many manufacturers producing them in China.
