Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a zeolite wheel RTO waste gas treatment device. Background Art

[0002] In recent years, waste gas treatment has become an important part of current development. RTO, or regenerative thermal incineration, is a commonly used method that can oxidize combustible waste gas into corresponding oxides and water at high temperatures, thereby purifying the waste gas. Based on RTO, RCO, or regenerative catalytic combustion, has been developed, which can completely oxidize pollutants under the action of a catalyst, and will not produce any secondary NOx pollutants, making it more energy-efficient and safer.

[0003] Before using RTO, it is usually necessary to concentrate the waste gas, and the zeolite wheel is one of the commonly used treatment devices. The zeolite wheel is usually divided into an adsorption zone, a desorption zone and a cooling zone. The zeolite wheel rotates at a certain speed, and the waste gas is adsorbed and removed from the waste by the adsorption zone, and then discharged after purification. The volatile organic matter adsorbed on the zeolite wheel is carried into the incinerator by the preheated gas in the desorption zone for treatment, and is cooled after desorption for the next adsorption.

[0004] When the zeolite rotor desorbs the adsorbed organic waste gas, high-temperature gas is only introduced from one side of the desorption zone and then discharged from the other side, which can easily cause one side of the zeolite rotor to be locally heated. When the cooling zone cools the zeolite rotor, the cooling gas is introduced from the side with less local heat and then discharged from the side with more local heat. This can easily lead to the side of the zeolite rotor with more local heat failing to cool down in time, causing damage to the zeolite rotor. In addition, there is dust in the organic waste gas, which can easily cause the zeolite rotor to be blocked after entering the zeolite rotor. Utility Model Content

[0005] The purpose of the utility model is to provide a zeolite rotor RTO waste gas treatment device, which avoids the problem of damage caused by the zeolite rotor being unable to cool down in time, and prevents dust from entering the zeolite rotor and causing blockage.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a zeolite rotor RTO waste gas treatment device, comprising a zeolite rotor, a heat exchanger and a regenerative incinerator, the zeolite rotor is divided into an adsorption zone, a desorption zone and a cooling zone, the zeolite rotor is provided with a filter box on one side of the adsorption zone, the adsorption zone and the filter box of the zeolite rotor are connected through a first air pipe, the filter box is fixedly connected with an air inlet pipe on one side away from the first air pipe, the zeolite rotor is fixedly connected with a second air pipe on one side away from the first air pipe, the other end of the second air pipe is fixedly connected with an exhaust port, an adsorption fan is fixedly installed in the middle of the first air pipe, the upper surface of the first air pipe is fixedly connected with a first cooling pipe at a position between the adsorption fan and the zeolite rotor, the first cooling pipe The other end of the tube is connected to the cooling zone, and a third air pipe is fixedly connected to the lower side of the cooling zone away from the first cooling pipe, and the other end of the third air pipe is fixedly connected to the input end of the heat exchanger, and a second cooling pipe is fixedly connected to the upper surface of the third air pipe, and the other end of the second cooling pipe is fixedly connected to the upper side of the cooling zone, and a desorption pipe is fixedly connected to the output end of the heat exchanger, and the other end of the desorption pipe is fixedly connected to the desorption zone, and a fourth air pipe is fixedly connected to the side of the desorption zone away from the desorption pipe, and the other end of the fourth air pipe is fixedly connected to the input end of the thermal storage incinerator, and a fifth air pipe is fixedly connected to the output end of the thermal storage incinerator, and the other end of the fifth air pipe is fixedly connected to the exhaust port, and a desorption fan is fixedly installed on the fourth air pipe.

The waste gas is sent to the adsorption area of ​​the zeolite rotor through the adsorption fan. At the same time, a part of the waste gas enters the cooling area through the first cooling pipe to cool the zeolite rotor. The waste gas entering the adsorption area is sent to the exhaust port through the second air pipe for discharge after being adsorbed by the zeolite rotor. The waste gas entering the cooling area enters the third air pipe. Part of the waste gas in the third air pipe enters the heat exchanger for heating, and the other part enters the second cooling pipe and is sent back to the cooling area to cool the zeolite rotor. The waste gas in the heat exchanger enters the desorption area through the desorption pipe to desorb the zeolite rotor, and then enters the fourth air pipe, and then enters the regenerative incinerator through the desorption fan of the fourth air pipe for incineration. The treated waste gas is sent to the exhaust port for discharge through the fifth air pipe.

[0008] Preferably, a filter plate is detachably mounted in the filter box, and the filter plate can filter dust in the exhaust gas, and when the filter plate is clogged, it can be disassembled, cleaned or replaced.
