Description

High-temperature desorption method of volatile organic waste gas treatment system

Technical Field

The present invention relates to a high temperature desorption method for a volatile organic waste gas treatment system, and more particularly, to a method for desorbing high boiling point organic waste gas (VOC) remaining in a desorption region of an adsorption rotor to recover the adsorption capacity of the adsorption rotor, thereby having high temperature desorption efficiency and being suitable for a volatile organic waste gas treatment system or the like in the semiconductor industry, the photoelectric industry or the chemical industry.

Background

At present, volatile organic gases (VOC) are generated in the manufacturing process of semiconductor industry or photoelectric industry, so that processing equipment for processing the VOC is installed in each factory to prevent the VOC from being directly discharged into the air to cause air pollution.

However, most of the existing processing equipment for processing Volatile Organic Compounds (VOC) installed in a factory adopts an adsorption rotating wheel to adsorb the VOC, but after a period of use, high boiling point substances are often not easy to desorb and remain on the adsorption rotating wheel, which directly affects the adsorption efficiency of the adsorption rotating wheel, therefore, the existing processing method is to entrust outside professional manufacturers to periodically wash the adsorption rotating wheel, so as to ensure the operating efficiency and airflow smoothness of the adsorption rotating wheel.

However, in the above-mentioned washing of the adsorption rotor at regular intervals, a large amount of clean water is required for cleaning, and thus a large amount of wastewater containing Volatile Organic Compounds (VOC) is generated, and at this time, the Chemical Oxygen Demand (COD) in the wastewater containing Volatile Organic Compounds (VOC) is very high and cannot be directly discharged after being treated by an in-plant wastewater treatment system, and thus a professional qualified waste cleaning company is required to perform the treatment.

Therefore, in view of the above-mentioned shortcomings, it is desirable to provide a high temperature desorption method for a voc emission gas treatment system with high temperature desorption performance, which allows a user to easily operate and assemble the system, so that the invention is intended to provide convenience for the user through careful research and design.

Another object of the present invention is to provide a high temperature desorption method for a VOC waste gas treatment system, and an auxiliary heater or a pipe heater can be additionally arranged through the hot gas conveying pipeline, or the high-temperature hot gas of the hearth of the incinerator is introduced into the hot gas conveying pipeline, or the high-temperature hot gas at the outlet of the hot side of the first heat exchanger is conveyed into the hot gas conveying pipeline, or the hearth of the incinerator is directly heated to raise the combustion temperature, in addition, the air volume can be adjusted by a desorption windmill, so that the temperature of high-temperature hot air entering a desorption area of the adsorption rotating wheel can be further increased by any one of the methods, the residual high-boiling-point organic waste gas (VOC) can be effectively removed, the energy-saving effect is achieved, and the overall usability is further improved.
