System for desorption of activated carbon and treatment of VOCs

Abstract

The invention provides a system for desorption of activated carbon and treatment of VOCs. The system comprises an insulation shell and further comprises an activated carbon desorption chamber, a high-temperature heating furnace, a heat exchange chamber and a fan arranged therein, wherein the activated carbon desorption chamber is laterally provided with a feeding port that communicates with a feeding door on the insulation shell; the activated carbon desorption chamber is provided with an air inlet communicating with the fan; the activated carbon desorption chamber is provided with an air outlet communicating with the interior of the insulation shell; a gas outlet pipe is arranged on the activated carbon desorption chamber and connected with a VOC in-tube burner arranged in the high-temperature heating furnace; the outlet end of the VOC in-tube burner is connected with a heat exchange coil which is arranged in the heat exchange chamber; and the air inlet end of the heat exchange chamber communicates with the interior of the insulation shell. The invention has the beneficial effects that activated carbon is desorbed at a high temperature; desorbed harmful VOC gas is heated and burned by using the high temperature at the same time and is degraded into carbon dioxide and water for harmless discharge; so the desorption of the activated carbon and treatment of the harmful gas are completed at the same time.

Description

technical field [0001] The invention relates to the technical field of activated carbon treatment devices, in particular to an activated carbon desorption and VOCs treatment system Background technique [0002] Activated carbon has a highly developed pore structure and a suitable specific surface area, is non-toxic and tasteless, and has a strong adsorption capacity for colored molecules of organic substances. It is often used as an excellent adsorbent and is widely used in medicine, metallurgy, food, and chemical industry. , military and environmental protection and other fields. In recent years, with the improvement of people's social awareness of environmental protection, the demand for activated carbon in environmental protection is increasing, and it is widely used in urban water supply purification, harmful gas adsorption, drinking water purification and industrial wastewater advanced treatment. However, due to the high price of activated carbon and the shortage of pr...

AI Technical Summary

Problems solved by technology

However, the current heating regeneration technology has problems such as high energy consumption, low desorption efficiency, and poor safety.

At the same time, there is a lack of equipment for the treatment of desorbed harmful gases, which is likely to cause secondary air pollution, so it is necessary to further improve it
