Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an RTO oxidation treatment device for waste gas treatment. Background Technology

[0002] The Real-Time Oxidation (RTO) unit for waste gas treatment is a highly efficient, energy-saving, and environmentally friendly device, mainly used to treat medium- to high-concentration organic waste gas. It heats the organic waste gas to high temperatures (typically above 760°C), causing the organic matter (VOCs) in the waste gas to be directly oxidized and decomposed into carbon dioxide and water, thereby achieving the purpose of purifying the waste gas pollutants.

[0003] Existing RTO devices often lack efficient preheating systems, or the design and operation of preheating systems are not optimized enough, resulting in insufficient temperature of exhaust gas before it enters the combustion chamber. When the exhaust gas temperature is insufficient, the organic matter inside may not be completely burned, leading to reduced combustion efficiency. This not only wastes energy but may also produce unburned pollutants, causing environmental pollution. Utility Model Content

[0004] The purpose of this invention is to provide an RTO oxidation treatment device for waste gas treatment, which improves the stability of the RTO oxidation treatment device and solves the problem of poor stability of the existing RTO oxidation treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An RTO oxidation treatment device for waste gas treatment includes a shell, inside which a preheating chamber, a combustion chamber, and a cooling chamber are respectively arranged. A first pipe is fixedly connected between the preheating chamber and the combustion chamber, and a second pipe is fixedly connected between the combustion chamber and the cooling chamber. Multiple preheating pipes are fixedly connected in a rectangular array inside the preheating chamber. A burner is fixedly connected to the side wall of the shell, with multiple combustion ends of the burner located inside the combustion chamber. Multiple coolers are fixedly connected through the shell at equal intervals on one side, with the cooling ends of the coolers located inside the cooling chamber.

[0007] Preferably, the upper end of the shell is provided with a chamber, the interior of which is connected to the upper end of the preheating pipe, and the lower end of the shell is provided with a cavity, the interior of which is connected to the lower end of the preheating pipe.

[0008] Preferably, a connecting pipe is fixedly connected to one side of the housing, one end of the connecting pipe is connected to the inside of the cavity, and the other end of the connecting pipe is connected to the inside of the combustion chamber.

[0009] Preferably, a pump body is fixedly connected inside the housing, a horizontal pipe is fixedly connected to the output end of the pump body, the output end of the horizontal pipe communicates with the interior of the chamber, and the input end of the pump body communicates with the interior of the combustion chamber.

[0010] Preferably, a conveying pipe is fixedly connected through the left side of the housing, and the conveying pipe communicates with the interior of the preheating chamber. A smoke exhaust pipe is fixedly connected through the upper end of the housing, and the smoke exhaust pipe communicates with the interior of the cooling chamber.

[0011] Preferably, the front side of the housing is provided with a plurality of sealing doors, which are respectively located inside the opening end of the preheating chamber, the opening end of the combustion chamber and the opening end of the cooling chamber, and the side wall of the sealing door is fixedly connected with a handle.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. Before exhaust gas treatment, multiple combustion points of the burner ignite to generate flames, which heat the interior of the combustion chamber. Then, a portion of the high-temperature airflow inside the combustion chamber is drawn in by a pump and transported to the interior of the chamber through a horizontal pipe. The high-temperature airflow flowing inside the chamber is dispersed into multiple preheating tubes, where it heats the tubes. The high-temperature airflow inside the preheating tubes then flows into the interior of the chamber. Finally, the airflow inside the chamber returns to the combustion chamber through a connecting pipe. Through the preheating and heat recovery process, the system can operate under more stable conditions, reducing malfunctions and downtime caused by temperature fluctuations, and improving the stability and reliability of the system.

[0014] 2. The exhaust gas inside the preheating chamber is preheated through the preheating pipe. The preheated exhaust gas then flows through pipe one into the combustion chamber, where it is burned at high temperature by flames generated at multiple combustion ends of the burner. This process oxidizes and decomposes the organic pollutants in the exhaust gas into harmless substances. The exhaust gas after high-temperature combustion then flows through pipe two into the cooling chamber, where it comes into contact with multiple coolers for cooling. The cooled gas stream is then discharged through the exhaust pipe. The preheating pipe further preheats the exhaust gas, ensuring it reaches a suitable combustion temperature before entering the combustion chamber. This helps accelerate the combustion reaction and improve combustion efficiency. Higher combustion efficiency means more thorough oxidation and decomposition of organic pollutants, thereby reducing the emission of incompletely burned pollutants. Attached Figure Description

Electronic valves are installed inside both the first pipe 106 and the second pipe 109. By adjusting the opening degree of the electronic valve inside the first pipe 106, the flow rate of waste gas flowing from the preheating chamber 101 to the combustion chamber 105 is controlled. Simultaneously, by adjusting the opening and closing degree of the electronic valve inside pipe 2 109, the flow rate of exhaust gas from combustion chamber 105 to cooling chamber 108 is controlled. Burner 002 adopts a multi-nozzle burner, and cooler 004 adopts a semiconductor cooler. Exhaust gas is transported inside preheating chamber 101, and hot air flows inside preheating pipe 104. The hot air heats preheating pipe 104, and the exhaust gas inside preheating chamber 101 is preheated through preheating pipe 104. The preheated exhaust gas flows to combustion chamber 105 through pipe 1 106. Multiple combustion points of burner 002 ignite to generate flames, and the exhaust gas is burned at high temperature by the flames, oxidizing and decomposing organic pollutants in the exhaust gas into harmless substances.

[0023] The upper end of the shell 001 is provided with a chamber 102, which is connected to the upper end of the preheating pipe 104. The lower end of the shell 001 is provided with a cavity 103, which is connected to the lower end of the preheating pipe 104. High-temperature airflow flows inside the chamber 102 and disperses to the interior of multiple preheating pipes 104. The preheating pipes 104 are heated by the flowing high-temperature airflow. Then, the high-temperature airflow inside the preheating pipes 104 flows into the cavity 103.

[0024] A connecting pipe 107 is fixedly connected to one side of the housing 001. One end of the connecting pipe 107 is connected to the inside of the cavity 103, and the other end of the connecting pipe 107 is connected to the inside of the combustion chamber 105.

The pump body 003 draws in some of the high-temperature airflow inside the combustion chamber 105 and then delivers the high-temperature airflow to the inside of the chamber 102 through the horizontal pipe 301. The pump body 003 is a high-temperature centrifugal pump.

[0026] A conveying pipe 110 is fixedly connected through the left side of the housing 001, and the conveying pipe 110 communicates with the interior of the preheating chamber 101. An exhaust pipe 111 is fixedly connected through the upper end of the housing 001, and the exhaust pipe 111 communicates with the interior of the cooling chamber 108. The conveying end of the conveying pipe 110 is connected to the output end of an external air pump. The external air pump delivers the waste gas to be treated to the interior of the preheating chamber 101 through the conveying pipe 110. The cooled airflow inside the cooling chamber 108 is discharged through the exhaust pipe 111. A filter screen is fixedly connected inside the exhaust pipe 111, and the airflow is further purified through the filter screen.

[0027] Multiple sealing doors 112 are rotatably provided on the front side of the housing 001. The multiple sealing doors 112 are located inside the opening end of the preheating chamber 101, the opening end of the combustion chamber 105, and the opening end of the cooling chamber 108, respectively. A handle 113 is fixedly connected to the side wall of the sealing door 112. The multiple sealing doors 112 facilitate the inspection and cleaning of the interior of the preheating chamber 101, the combustion chamber 105, and the cooling chamber 108.

[0028] In this invention, before the exhaust gas is treated, multiple combustion points of the burner 002 are ignited to generate flames, which heat the interior of the combustion chamber 105. Then, a portion of the high-temperature airflow inside the combustion chamber 105 is drawn in by the pump body 003 and transported to the interior of the chamber 102 through the horizontal pipe 301. The high-temperature airflow flowing inside the chamber 102 is dispersed and flows into multiple preheating pipes 104, where it heats the preheating pipes 104. Then, the high-temperature airflow inside the preheating pipes 104 flows into the chamber 103, and then the airflow inside the chamber 103 flows back to the interior of the combustion chamber 105 through the connecting pipe 107.

[0029] After being heated by multiple preheating pipes 104, the external air pump delivers the waste gas to be treated to the preheating chamber 101 through the delivery pipe 110. The waste gas inside the preheating chamber 101 is preheated by the preheating pipes 104. The preheated waste gas flows to the combustion chamber 105 through pipe 106. The waste gas is then subjected to high-temperature combustion by the flames generated by the multiple combustion ends of the burner 002, which oxidizes and decomposes the organic pollutants in the waste gas into harmless substances. The waste gas after high-temperature combustion flows to the cooling chamber 108 through pipe 2 109. The waste gas comes into contact with multiple coolers 004 and is cooled by the multiple coolers 004. The cooled airflow is discharged through the exhaust pipe 111. At the same time, the airflow is further purified by the filter screen inside the exhaust pipe 111.
