Spray towers are widely used in high-temperature flammable environments for industrial waste gas purification and organic waste gas treatment. They are essential equipment in modern waste gas management systems.
Here are six common issues and their solutions related to spray towers:
1. **Clogged Nozzles**:
This can happen when the Water Tank contains excessive dust and impurities. To address this, inspect the filter plate for damage, ensure the water pump inlet has a functional filter net, and check if the bottom filter of the pump is intact. If any of these components are faulty, they need to be repaired or replaced promptly. To disassemble the nozzle, first remove the window screw and panel. Enter the tower and unscrew the nozzle counterclockwise. Turn on the water pump (using clean water) for about two minutes, then reinstall the nozzle clockwise.
2. **Filling Blockage**:
Dusty or sticky impurities in the exhaust gas can accumulate on the filler balls, especially in cases like paint spraying or organic waste gases. Check for these causes and add cleaning solution and mild detergent to the water tank for a thorough cleaning. If the filler becomes too clogged, consider replacing it or removing it for cleaning. Reinstall the cleaned filler or use new ones. Regularly add cleaning solution and detergent to the water tank to keep it free of debris. Use a flocculant if there's any sediment to maintain clean water.
3. **Defogger Layer Water Leakage**:
Insufficient defogging material or improper fan settings could lead to water passing through the defogger layer. To fix this, increase the defogging layer's filler, lower the grid plate inside the tower, or adjust the fan's air volume using its inverter.
4. **Filling Piling Up**:
Excessive fan airflow can push the filling material into a heap. To resolve this, remove the window panel, spread the filling evenly, and cover it with a grid panel. Alternatively, reduce the fan's air volume by adjusting the inverter.
5. **Water Overflowing from the Tank**:
Mismatched gas inlet and outlet sizes or fan specifications can cause water to spill out after the fan is turned off. Adjust the fan's air volume via its inverter, enlarge the gas inlet and outlet, or regulate the float valve to control the water level.
6. **Nozzle Not Emitting Water**:
A malfunctioning water pump, low water levels, blocked nozzles, or obstructed pump inlets can cause this issue. Ensure the pump is functioning correctly, check the water level, and refill if necessary. Also, clear any obstructions in the nozzles or pump inlet.
In conclusion, maintaining spray towers requires regular checks and timely maintenance to ensure optimal performance and longevity.
