[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The utility model provides a zeolite wheel RTO waste gas treatment device, please refer to Figure 1-2 , comprising two dry filters, one of which is connected to a zeolite adsorption mechanism through a conduit, the zeolite adsorption mechanism is connected to a first desorption fan through a conduit, the first desorption fan is connected to an air mixing box through a conduit, the air mixing box is connected to an RTO fan through a conduit, the RTO fan is connected to a flame arrester through a conduit, an exhaust pipe is installed on the flame arrester, the flame arrester is connected to an RTO incinerator through a conduit, and a purge pipeline is installed on the RTO incinerator.

[0022] The exhaust port of the RTO incinerator is connected to an RTO waste gas emission pipeline, and one end of the RTO waste gas emission pipeline away from the RTO incinerator is connected to a chimney.

[0023] The zeolite adsorption mechanism is connected to an adsorption fan and a first fresh air fan through a conduit, the first fresh air fan is connected to a heat exchanger through a conduit, and the heat exchanger is connected to a heat outlet of the RTO incinerator through a conduit.

[0024] The zeolite adsorption mechanism is connected to the heat exchanger through a conduit, and a bridge pipe is connected to the connecting pipe between the first fresh air blower and the heat exchanger and the connecting pipe between the zeolite adsorption mechanism and the heat exchanger, and a temperature regulating valve is installed on the bridge pipe.

[0025] A burner is installed on the RTO incinerator, a fuel inlet of the burner is connected to a gas supply pipeline, and the burner is connected to a combustion-supporting fan through a conduit.

[0026] The RTO incinerator is connected with a back-blowing blower through a branch pipe.

[0027] Another dry filter is connected to several activated carbon adsorption devices through a conduit, each activated carbon adsorption device is connected to a constant temperature box through a conduit, the constant temperature box is connected to a second fresh air fan through a conduit, and the second fresh air fan is connected to the RTO incinerator through a conduit.

[0028] An adsorption valve is installed on the conduit connecting the dry filter and the activated carbon adsorption device below, and a desorption valve is installed on the conduit connecting the thermostatic box and the activated carbon adsorption device.

[0029] The exhaust port of the activated carbon adsorption device is connected to the chimney and the second desorption fan through a conduit, the second desorption fan is connected to a wind mixing box through a conduit, and a third adsorption fan is installed on the conduit connecting the chimney and the activated carbon adsorption device.

[0030] The exhaust gas passes through the concentration wheel adsorption area to adsorb (VOC) to achieve a purification effect. The adsorbed (VOC) is desorbed in the desorption area by a small amount of hot air. Thus, the concentration effect is achieved;

[0031] Adsorption process: The adsorption drum (rotor) is divided into multiple zones for adsorption, which are filled with granular, honeycomb, and fiber zeolite modules. When the exhaust gas passes through the adsorption bed, the VOC molecules are intercepted to achieve the purpose of purification;

[0032] Desorption process: After the medium absorbs a certain amount of VOC, it will be desorbed before the safe threshold of penetration concentration is reached. Hot air (180-220℃) is introduced to perform analysis and regeneration by heating and changing pressure. The high-concentration exhaust gas removed from the desorption process is introduced into the combustion furnace for thorough decomposition.

[0033] Cooling process: The medium is cooled to room temperature to restore adsorption performance. It can be cooled by cold air or directly by exhaust gas, depending on the application.

[0034] During specific use, part of the exhaust gas enters the upper dry filter through the pipeline for treatment. After the exhaust gas is treated by the dry filter, the exhaust gas is treated in the zeolite adsorption device, and then enters the air mixing box under the action of the first desorption fan, and then enters the RTO combustion furnace. After being treated in the RTO combustion furnace, it can return to the heat exchanger;

[0035] Of course, the waste gas treated by the zeolite adsorption device enters the air mixing box for mixing under the action of the desorption fan, and then enters the RTO combustion furnace for treatment;

[0036] Of course, part of the original exhaust gas is treated in the dry filter below and then enters the RTO combustion furnace for treatment; similarly, the exhaust gas can also enter the heat exchanger through the pipeline. Of course, if the exhaust gas is fully treated with activated carbon, it can also be discharged into the chimney through the pipeline for discharge;

[0037] The waste gas treated by the RTO combustion furnace can also be discharged through pipes and chimneys.

[0038] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
