What measures will the dust collector take to deal with sticky dust

The solution of dust collector to deal with sticky dust involves many aspects, including the selection, pretreatment, operation optimization and maintenance of dust collector. Here are some specific solutions:

1. Choose a suitable dust collector

Wet dust collector: For hydrophilic sticky dust, wet dust collector (such as spray tower, Venturi scrubber, etc.) is an ideal choice. They achieve efficient dust capture through the mixing, coagulation and precipitation of water and dust. However, the use of wet dust collector will bring about the problem of wastewater treatment, which needs to be solved by enterprises in the subsequent links.

Plastic sintered plate dust collector: Plastic sintered plate dust collector uses specially sintered plastic sintered plate as the filter medium. Its surface has a unique microporous structure and hydrophobic properties, which can effectively prevent the adhesion of sticky dust. At the same time, the plastic sintered plate dust collector can be cleaned by mechanical vibration or backblowing, avoiding the problem of difficult removal of sticky dust. However, it should be noted that when the plastic sintered plate dust collector handles high humidity or flammable and explosive dust, additional protective measures are required.

Electrostatic precipitator: For sticky dust with a certain conductivity, an electrostatic precipitator (such as an electric bag composite dust collector) is also a good choice. The electrostatic precipitator uses electrostatic attraction to capture dust and cleans it by vibration or backblowing. It has high processing efficiency, stable operation, and a certain adaptability to sticky dust. However, for non-conductive or poorly conductive sticky dust, the treatment effect of the electrostatic precipitator may be limited.

Pulse jet bag dust collector: By improving the filter material (such as using coated filter material), optimizing the cleaning method (such as high-frequency pulse cleaning), and appropriately reducing the filtration wind speed, the pulse jet bag dust collector can also improve the treatment effect of sticky dust to a certain extent. However, this solution requires regular maintenance, and the cleaning frequency and intensity need to be finely controlled to prevent the filter bag from being damaged prematurely.

2. Pretreatment

Before entering the dust collector, the dust-laden gas is pretreated, such as spray humidification, heating, condensation, etc., to change the physical properties of the dust and reduce its adhesion. This method helps to reduce the burden on the dust collector and improve the dust removal efficiency.

3. Operation optimization

Optimize the cleaning method: For sticky dust, more frequent or more intense cleaning operations are required. Optimizing the pulse jet system, such as increasing the jet pressure, frequency, or using online cleaning methods, can more effectively remove dust from the filter bag.

Set up a heating device: Setting a heating device inside or around the filter bag can increase the temperature of the filter bag, reduce the adhesion of the dust, and help remove the dust accumulation on the filter bag.

4. Regular maintenance

Regularly inspect and maintain the dust collector, including cleaning the filter bag, checking the seals, replacing damaged parts, etc., to ensure its normal operation. At the same time, train the operators to understand how to handle sticky dust and follow the correct operation and maintenance procedures.

5. Other measures

Use of additives: Add some chemical additives such as surfactants or anti-caking agents to the gas to change the surface properties of the dust and reduce its adhesion.

Design optimization: In the design stage of the dust collector, you can consider increasing the filtration area, optimizing the airflow distribution, etc. to improve its ability to handle sticky dust.

In summary, the solution for dust collectors to deal with sticky dust needs to comprehensively consider the selection, pretreatment, operation optimization and maintenance of dust collectors. By selecting a suitable dust collector, performing necessary pretreatment, optimizing operation and maintenance measures, the emission and diffusion of sticky dust can be effectively controlled to protect the production environment and personnel health.
