What are the advantages of using bag filter in the workshop


In the daily production activities of the factory workshop, dust is an important factor affecting the production of the workshop, because sometimes, if the dust removal work in the workshop is not done well enough, it will cause harm to the workers' body and mind, and a series of potential safety hazards will follow. Most industrial workshops will encounter such problems, so what kind of dust collector can help the whole industrial industry better improve the production space?

Of course, bag filter is the first choice. The emergence of bag filter has been recognized by the bosses of many industrial industries and has well solved the environmental problems of industrial workshops. Let Kehan environmental protection editor introduce the benefits of bag filter in the workshop in detail.

What are the benefits of using bag filter in the workshop?

1. The low emission concentration can adapt to the lower and lower emission value: the application of needle punched felt or glass fiber coated filter material in bag filter can reduce the emission concentration to less than 10mg / Nm3, which can not be compared with other types of dust collectors. The newly revised air pollution emission standard for cement industry stipulates that the emission value of particulate matter is 50mg / Nm3 for thermal equipment and 30mg / Nm3 for ventilation equipment. The water dust remover has been eliminated, and the cyclone has also been eliminated for end dust removal. The electrostatic precipitator must also update the technology and increase the cost in order to shoulder the heavy responsibility.

2. The advanced control technology realizes the remote control of the central control room: with the large-scale dust removal equipment and the improvement of labor productivity, the cement production lines now built adopt distributed control and are equipped with a central control room. At present, the bag filter itself has a control cabinet. The microcomputer or PLC programmable controller is used to automatically control the working state of the bag filter, which has the functions of temperature, pressure display, overtemperature, fault alarm, etc. its extended interface can fully transmit the working signal to the central control room, and remotely control and manage the bag filter in the central control room.

3. It can operate synchronously with the host equipment: it can better meet the requirements of the new emission standard on the operation rate of dust removal equipment. The newly revised emission standard of air pollutants for the cement industry requires that the newly-built cement kiln ensure that the dust removal device can still operate normally in case of production process fluctuation, and abnormal discharge is prohibited. Unlike the electrostatic precipitator, the bag filter stops operation due to excessive Co, which is less affected by the fluctuation of production process. Even if the dust collector itself has faults, because it adopts multi box structure, it can carry out off-line maintenance and bag replacement for the faulty room, and the other rooms can still work normally, which can ensure synchronous operation with the host equipment.

4. It has the function of reducing harmful gases: the dust in the cement industry is mostly alkaline substances, and the harmful gases containing sulfur oxides, nitrogen oxides and halides can react with alkaline substances and be absorbed. The filter bag of the bag filter becomes the reaction carrier. The experimental results show that the harmful gases are reduced by about 50% through the bag filter, and its function will be further developed, To meet the requirements of reducing harmful gas emission in the cement industry.
