1. Introduction
Bag dust collector is common equipment for industrial dust treatment. In practical application, customers may encounter problems of poor dust removal and decreased ventilation rate. This may not only affect the production environment, but also cause equipment damage. Next, we will give reasons of these two problems and provide corresponding solutions.
2. Reasons
Reasons for poor dust removal effect
①Filter bag aging or damage: after long-term use, filter bag may be damaged due to aging, wear or external factors, this will affect the dust removal effect.
②Filter bag clogged: if dust accumulated on dust collector not being cleaned in time, it will clog filter bag and then affect dust removal effect.
③Uneven airflow distribution: if airflow is unevenly distributed, some filter bags may overload while others underload, this will result in uneven dust removal effect.
④Improper equipment design or installation: if the equipment is not designed or installed properly, it may also lead to poor dust removal effect.
Reasons for decreased ventilation rate
①Increased filter bag resistance: as dust accumulates on filter bag, the resistance will gradually increase, this will affect ventilation rate.
②Pulse cleaning system failure: pulse valve blockage and insufficient air source pressure may lead to incomplete cleaning, this will also affect ventilation rate.
③Equipment aging: after long-term use, the equipment may occur problems of ageing and wear, this will result in decreased ventilation rate.
3. Solutions
- Regularly check and replace filter bag: check and replace aged or damaged filter bags in time and choose filter bags with good quality.
- Avoid clogging of filter bag: mechanical vibration or pulse airflow can be used to remove dust, these methods have good dust removal effect.
- Adjust airflow distribution: optimize the design of air inlet and outlet to ensure even airflow distribution. For example, add diversion device or adjust the order of filter bags.
- Check and maintain pulse cleaning system: regularly check pulse valve and cylinder to ensure their normal operation.
- Equipment upgrades: if the equipment is aging or improperly designed, to upgrade the equipment can improve dust removal effect and ventilation rate
- Strengthen operation training: ensure that operators are familiar with operating instruction and maintenance Guideline, to avoid problems caused by incorrect operation.
- Establish maintenance records: record information such as: operation status, maintenance status and replacement time of filter bag, will help to find problem in time and take effective protective measures.
4. Summary
Methods mentioned above can effectively solve the problems of poor dust removal effect and decreased ventilation rate of bag dust collector. This is helpful to improve operating efficiency and service life of bag dust collector. Meanwhile, it can reduce operating and maintenance costs and improve environmental protection effect.
