Degreasing Exhaust Gas Purification Furnace

Degreasing Exhaust Gas Purification Furnace

The 1000℃ VOC Exhaust Gas Purification Furnace is a high-temperature purification device specifically designed for VOC organic waste gas generated during degreasing, dewaxing, degumming, and heat treatment processes. The equipment employs high-temperature thermal oxidation technology, heating the organic waste gas to its decomposition temperature to fully oxidize and decompose volatile organic compounds (VOCs) into carbon dioxide and water, achieving harmless treatment of the waste gas. The entire unit utilizes PID intelligent temperature control, SCR silicon controlled rectifier power adjustment, and multiple safety protection systems, featuring precise temperature control, high processing efficiency, stable operation, and convenient maintenance.

Product Features

1. Five-sided Heating, Temperature Uniformity ±1℃

Utilizes a five-sided heating design (high-temperature alloy resistance wire for the furnace door and bottom, silicon carbide rods for the sides and rear), with three independent temperature control electrical systems (one for the furnace door, one for the furnace bottom, and one for the sides and rear). Temperature control accuracy is ±0.5-1℃, and furnace temperature uniformity is ±1℃ (depending on furnace size), ensuring stable and reliable waste gas treatment temperature.

2. Three-chamber Regenerative Oxidation, Purification Efficiency ≥95%

Maximum temperature 1000℃, normal operating temperature 750℃. Heats organic waste gas to above 750℃, oxidizing and decomposing VOCs in the waste gas into carbon dioxide and water. Waste gas treatment capacity is 80 cubic meters/hour, with a treatment efficiency of 95%. Heating rate is adjustable at 40℃/min, quickly reaching the operating temperature.

3. Programmable PID Self-tuning + SCR Control

Employs programmable PID self-tuning control, combined with imported SCR module trigger control (phase-shift triggering or zero-crossing triggering). Equipped with 30-segment programmable control, it can achieve arbitrary slope temperature rise and fall control, and features programmable commands such as jump (cycle), run, pause, and stop. Output voltage, current, or power is continuously adjustable, exhibiting constant voltage, constant current, or constant power characteristics.

4. Regenerative Furnace Bottom + Reinforced Furnace Top for Superior Temperature Uniformity

The regenerative furnace bottom and reinforced furnace top design further enhance the temperature uniformity within the furnace chamber. The air inlet is located at the bottom of the furnace, and the air flow rate can be adjusted via valves to accommodate the treatment needs of waste gases with different concentrations.
