Abstract

Abstract

Electrothermal regeneration is a kind of activated carbon material regeneration method with a short treating time, strong versatility and low energy consumption, and it has attracted much attention in the field of volatile organic compounds treatment, indoor air purification and chemical protection. In this paper, we used activated carbon fiber mesh to fill the adsorption bed, and systematically studied the effects of energizing voltage, specific velocity of purge gas, and bed water adsorption on the electrothermal behavior of the adsorption bed. The results showed that:setting the energizing voltage to 50 V and inputting 1 W·h electrical energy for the drying bed, the bed could rise to 144.6℃, which was 63.8℃ higher than that at 20 V. Increasing the specific velocity of purge gas reduced the temperature at the end of the electrothermal process and prolong the heating time. There was a temperature rise platform in the water adsorption bed during electric heating. Under the conditions of a voltage of 40 V and a specific speed of purge gas flow of 0.08 L/(min·cm²), the heating platform could last up to 30 minutes according to different water adsorption rates. In addition, the energizing voltage and purge gas could affect the temperature and duration of the heating platform.
