小型除尘器设备内部腐蚀的主要原因是气体温度接近露点，甚至低于露点. 因此，改进工艺系统和操作方法，避免冷凝现象，是防止袋式除尘器腐蚀的有效措施. The method of internal corrosion of small dust collector equipment. The main reason for the internal corrosion of small dust collector equipment is that the gas temperature is close to or even lower than the dew point. Therefore, improving the process system and operating methods to avoid condensation and prevent the bag duster from corrosion Effective measures.
What are the measures to prevent corrosion of small vacuum cleaner equipment:
The high SO2 content and high moisture content in the flue gas are the main reasons for corrosion. Because once the wall is condensed, sulfite sulfate will be formed, and corrosion will occur in the weak protection area.
The flue gas temperature is too low, creating conditions for acid formation and SO2 corrosion.
Some users have misunderstood the methods of internal corrosion problems in small dust collectors. Similar to the kiln tail bag dust collector, in order to prevent the bag from being stuck, the bag room is externally insulated, while the clean air room believes that the flue gas must be discharged to the outside, and the four walls have no external insulation. As a result, the fumes are heavily condensed here, causing severe corrosion that should not have occurred.
The top cover is not tightly sealed around, cold air invades, and there is also condensation and rust nearby.
What are the measures to prevent corrosion of small vacuum cleaner equipment
Reasons and countermeasures for rust prevention in small vacuum cleaner equipment:
Methods for internal corrosion problems in small dust collector equipment when designing and manufacturing equipment. According to the nature of the flue gas, especially the content of SO2 and H2O, appropriate rust prevention measures should be taken, including the rust prevention level achieved by painting (usually sa2.5), the choice of primer and topcoat, the number of coatings and The thickness of each layer; ensure that the construction is in place; the temperature resistance level of the coating should be higher than the possible high flue gas temperature to prevent the coating from overheating. Under high corrosion conditions, galvanization cannot be generally used, but spray coating and asphalt paint should be used Or high temperature and humidity resistant paint. Clean air interior walls and internal components such as blowpipes should also be treated similarly, generally can not be painted.
For the equipment used in the kiln type and coal grinding system, the overall external insulation must be done well, leaving no hidden danger of condensation.
Production operation should ensure that the operating temperature is 20 to 30 ° C higher than the dew point, which can prevent the bag from sticking and prevent condensation and corrosion
Seal and maintain the bag filter.
