China TEG Cleaning Equipment - High-Efficiency Triethylene Glycol Furnace from Reliable Suppliers and Factory
Materials of Device
Tank Body & Furnace Lid
Produced using SUS304 & 6mm board, featuring pressure testing and leakage check after forming.
The Jacket & Shell
Jacket made of 5mm heat-resisting stainless steel plate (GB-150 standard); shell made of 2mm stainless steel. Filled with high-quality aluminum silicate cotton insulation. All appearance welds undergo kerosene leakage testing. Features a bottom protection plate thicker than the insulation layer in a fan-shaped design to prevent TEG medium drops from causing security incidents.
Flanges & Steel Pipe
Components in contact with TEG are manufactured from heat-resistant stainless steel.
Level Gauge
Stainless steel magnetic coupling plate type level gauge, equipped with a level lower limit alarm.
Electric Heater
Stainless steel heating pipe with 60kW total power. Composed of 33 "U" type stainless steel electric heating elements (30 active, 3 spare, 2kW each) welded directly into the furnace. Heating wire made of Ni20Cr80 alloy with a service life of at least three years.
Hanging Basket
Heat-resistant stainless steel material, featuring 7 layers for cleaning spinnerets.
Condenser
Stainless steel material with a shell and tube type structure. Condensing area is 3.5m².
Pneumatic Components
Includes cylinder, manual valve, and steam source triple.
Insulation Cotton
High-temperature aluminum silicate cotton for optimal thermal retention.
Control System
According to the working principle and requirements of the TEG cleaning furnace, the system utilizes two sets of instrument controls: one to regulate the electric heater temperature with anti-dry protection, and another to control the TEG medium temperature.
Double Safety Interlock: Cuts off main heating power and triggers sound/light alarms during over-temperature events.
PID Control: Supports manual and auto-tuning to drive the solid-state relay heating control device.
Level & Pressure Protection: Interlock stops the heater if TEG is below the set level, if the junction box lacks pressure, or if the condenser is without water/low pressure.
Auto-Shutdown: System automatically shuts down once the cleaning process is completed.
Frequently Asked Questions
What materials are used for the main tank and furnace lid?
The tank body and furnace lid are manufactured using SUS304 and a 6mm board. They undergo strict pressure testing and leakage checks after forming to ensure maximum safety.
How does the electric heater ensure safe operation and longevity?
The heater has a total power of 60kW, consisting of 33 "U" type stainless steel elements (30 active, 3 spare). The heating wire is made of Ni20Cr80 alloy, which ensures a service life of at least three years. Additionally, it features anti-dry protection and level gauge interlock safety.
What safety mechanisms protect against over-temperature conditions?
The control system uses two sets of instrument safety interlocks. If an over-temperature state occurs, the system automatically cuts off the main heating power and triggers a sound and light alarm.
What happens if the TEG medium level drops too low?
There is an interlock protection between the heater and the magnetic coupling plate level gauge. If the TEG falls below the set level, the heating elements will automatically stop working to prevent damage.
How does the system handle condenser water issues?
If the condenser is without water or the water pressure is too low, the system will trigger an alarm and automatically cut off the source.
Does the cleaning furnace shut down automatically after processing?
Yes, the system features an automatic shutdown function that triggers immediately when the cleaning process ends.
