This unit is designed for the water bath absorption treatment of NMP-containing waste gas from coating drying processes. It requires a three-phase AC380V±10%, 50Hz power supply and a 1.5KW electrical connection.
- Inlet Air Temperature Limit: The inlet air temperature must not exceed 150°C to prevent thermal damage to the water bath absorption system.
- Water Supply and Tank Capacity: The water tank has a maximum volume of 100L and is designed to operate with tap water, requiring periodic refilling to maintain absorption efficiency.
- Ventilation and Airflow Constraint: The single-stage ventilation area is limited to ≤1600mm², and the system is designed for a treatment capacity of 2200m³/h, requiring a centrifugal fan with a static pressure of 2000Pa.
- Duct Connection Requirement: Both the air inlet and outlet pipes have a Φ102mm interface, requiring connection to a 4-inch aluminum foil air pipe for proper exhaust gas routing.
This procedure outlines the safe and effective operation of the water bath absorption unit for NMP waste gas treatment. It covers pre-start checks, startup, and shutdown steps to ensure proper function and safety.
Required Equipment: 4-inch aluminum foil air pipe, Tap water supply
- Verify power supply
Verify that the three-phase AC380V±10%, 50Hz power supply is connected and the unit is properly grounded. - Connect ducting
Connect the 4-inch aluminum foil air pipes to the Φ102mm inlet and outlet interfaces, ensuring a secure and airtight seal. - Fill water tank
Fill the water tank with tap water to the required level, ensuring the water bath area is adequately covered. - Start the unit
Start the unit and allow the water pump and centrifugal fan to reach operating speed, confirming the air flow is established. - Monitor inlet temperature
Monitor the inlet air temperature to ensure it does not exceed 150°C during operation. - Shutdown procedure
After completing the treatment process, turn off the unit and disconnect the power supply, then drain the water tank if necessary.
What is the maximum inlet air temperature and how does it affect the Atomfair-SEPU-8542's performance?
The maximum inlet air temperature is 150°C. Operating above this limit could compromise the water bath absorption efficiency and risk thermal damage to the unit's internal components, potentially reducing the recovery of NMP and dust from the waste gas stream.
Can the Atomfair-SEPU-8542 be integrated with existing 4-inch ductwork and what are the connection requirements?
Yes, the unit is designed for direct integration with 4-inch aluminum foil air pipes, as both the inlet and outlet interfaces are Φ102mm. This standard connection simplifies retrofitting into existing coating machine exhaust systems, but ensure the ductwork is properly sealed to maintain the required static pressure of 2000Pa for optimal air flow.
What are the utility and installation prerequisites for the Atomfair-SEPU-8542?
The unit requires a three-phase AC380V±10%, 50Hz power supply with a total power consumption of 1.5KW. It also needs a tap water connection for the water bath and a floor area of approximately 1100mm×800mm, with a clearance height of at least 1650mm. The unit weighs about 300kg without water, so a reinforced floor or stand is recommended.
The Atomfair-SEPU-8542 Solvent Exhaust Purification Unit is a two-stage water bath scrubber rated at 2200 m³/h for NMP-laden exhaust from coating dryers, with a stainless steel fully-welded inner liner and a 100 L water tank. Its self-priming air intake and direct tap water compatibility simplify installation, but the 300 kg dry weight and 1.5 kW three-phase power requirement demand dedicated lab infrastructure.
Positive
- Two-stage water bath recovery: The two-stage water bath treatment delivers efficient recovery of NMP and dust from coating dryer exhaust, with a single-stage ventilation area of ≤1600 mm² per stage, enabling high-capacity purification at 2200 m³/h.
- Corrosion-resistant welded liner: The stainless steel fully-welded inner liner provides superior corrosion resistance against solvent-laden gas, while the powder-coated outer shell ensures durability in industrial coating environments.
Trade-offs
- Requires three-phase power: The unit operates on three-phase AC380V±10%, 50Hz with 1.5KW total power, requiring a compatible three-phase electrical supply that may not be available in all laboratory or light-industrial settings.
- Heavy and space-intensive: Weighing approximately 300kg dry and measuring 1100mm×800mm×1650mm, the unit demands substantial floor space and structural support, plus a 100L water tank that adds significant weight when filled.
