Triethylene Glycol Cleaning Furnace - Factory Suppliers in China for Efficient Polyester Cleaning Solutions
Materials of Device
1. Tank Body & Furnace Lid
Produced using SUS304 & 6mm board, with pressure testing and leakage checks performed after forming.
2. Jacket & Insulation
Jacket made of 5mm heat-resisting stainless steel plate (GB-150 standard); 2mm stainless steel shell. Filled with high-quality aluminum silicate cotton insulation. Features kerosene leakage tested appearance welds and a thick bottom protection plate to prevent TEG medium drops into the cotton insulation.
3. Flanges & Steel Pipe
All contact parts with TEG flanges and steel pipes are made of heat-resistant stainless steel.
4. Level Gauge
Stainless steel magnetic coupling plate type level gauge, equipped with a level lower limit alarm.
5. Electric Heater
Stainless steel heating pipe with 60kW power (33 "U" type elements, 30 in use, 3 spare). Features Ni20Cr80 alloy heating wire with a service life of no less than three years.
6. Hanging Basket
Made of heat-resistant stainless steel material, configured with 7 layers for cleaning spinnerets.
7. Condenser
Stainless steel material with a shell and tube type structure, offering a condensing area of 3.5m².
8. Pneumatic Components
Includes cylinder, manual valve, and steam source triple components.
9. Insulation Cotton
High-temperature aluminum silicate cotton used for optimal thermal protection.
Control System
According to the working principle and requirements of the TEG cleaning furnace, the system utilizes two sets of instrument control: one set controls the electric heater temperature and provides anti-dry protection, while the other controls the TEG medium temperature. These two sets of instruments feature a safety interlock for double protection. In the event of over-temperature, the main heating power is cut off immediately, accompanied by a sound and light alarm to ensure normal operation and fault self-protection.
The instrument features PID manual and auto-tuning capabilities to set optimal parameters, outputting excellent control signals to drive the solid-state relay heating control device. This device includes automatic temperature cooling and fault self-diagnosis protection to guarantee precise temperature control. Additionally, a double-cut function operates on both time and temperature to ensure the cleaning effect.
To ensure safe operation, the heater and magnetic coupling plate level gauge feature interlock protection: when the TEG level falls below the set limit, the heating element is disabled. Furthermore, if there is no pressure in the heater junction box, the heating component will not work. If the condenser lacks water or the water pressure is too low, the system triggers an alarm and automatically cuts off the source. Upon completion of the cleaning process, the system automatically shuts down.
Frequently Asked Questions
The tank body and furnace lid are produced using SUS304 and a 6mm board. Pressure testing and leakage checks are strictly performed after forming.
The device uses a stainless steel magnetic coupling plate type level gauge with a lower limit alarm. It is interlocked with the heater; if the TEG level falls below the set limit, the heating element will not work.
The electric heater has a heating power of 60kW, consisting of 33 "U" type stainless steel elements (30 in active use, 3 spare). The heating wire is made of Ni20Cr80 alloy, ensuring a service life of at least three years.
The system features a double instrument safety interlock. If over-temperature occurs, it cuts off the main heating power and triggers a sound and light alarm. It also includes anti-dry protection, no-pressure protection for the heater junction box, and low water pressure alarms for the condenser.
Yes, once the cleaning process ends, the control system has an automatic shutdown function to stop the operation safely.
