<p>A zero-energy device for purifying volatile organic compounds comprises: an adsorption and desorption concentrator, an incinerator and a flow-mixing device; an adsorption unit of the adsorption and desorption concentrator is connected with an exhaust gas pipe and a gas purification pipe, and the gas of volatile organic compounds is introduced into the adsorption unit through the exhaust gas pipe and treated there to generate a purified gas which is then discharged into the gas purification pipe and discharged outside through a chimney. A desorption unit is connected between a concentrated gas pipe and a re-purified gas pipe. The re-purified gas incinerated in the incinerator is introduced into the flow-mixing device and then introduced into the desorption unit through the re-purified gas pipe, and the re-purified gas serves as a desorption gas source and a heat source of the desorption unit. A concentrated gas is generated through the desorption gas source of the desorption unit, the concentrated gas then flows into the inlet of the incinerator and then is incinerated to generate a re-purified gas, thus the continuous desorption cycling of the adsorption and desorption concentrator is formed; the device of the present invention can almost reach zero energy consumption by means of the heat released owing to thermal decomposition of the volatile organic compounds and the waste heat of the incinerator.</p> |
