Description

Technical Field

[0001] This utility model relates to the field of RTO equipment, and in particular to a rotary RTO equipment for treating chemical waste gas. Background Technology

[0002] Rotary RTO, also known as a rotary regenerative oxidation furnace, works by oxidizing combustible gases into corresponding oxides and water at high temperatures, thereby purifying the waste gas and recovering the heat released during decomposition. The waste gas decomposition efficiency reaches over 99%, and the heat recovery efficiency reaches over 95%.

[0003] When rotary RTO equipment treats chemical waste gas, its heat cannot be well utilized, which leads to energy waste. Secondly, it cannot selectively discharge waste gas according to its quality, and therefore cannot guarantee whether the discharge will have an impact on the environment.

[0004] Therefore, it is necessary to propose a rotary RTO device for treating chemical waste gas to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a rotary RTO device for treating chemical waste gas, which can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rotary RTO device for treating chemical waste gas includes a device body, a top seat installed on the top of the device body, a detection component installed in the inner cavity of the top seat, a ceramic packing bed installed at the bottom of the inner cavity of the device body, and a rotary valve installed at the bottom of the device body.

[0008] An exhaust pipe is installed on the top of the side of the top seat, a chimney is installed on the side of the exhaust pipe, an air supply assembly is installed on the outer wall of the equipment body, a filter screen is installed in the inner cavity of the air supply assembly, and a heating oil pipe is installed in the inner cavity of the equipment body.

[0009] Preferably, a base is symmetrically installed around the bottom of the device body, a burner is installed on the side of the device body, the burner extends into the inner cavity of the device body, and a servo motor is installed at the center of the top of the top seat.

[0010] Preferably, an exhaust fan is rotatably connected to the inner cavity of the top seat, and the servo motor drives the exhaust fan through a rotating shaft. A gas sensor is installed in the center of the bottom of the detection component, and a first air pipe and a second air pipe are symmetrically installed on both sides of the bottom of the detection component.

[0011] Preferably, the outer flanges of the first and second air pipes are connected to solenoid valves, the first air pipe is connected to the exhaust pipe, and the second air pipe is used to pass through the outside of the equipment body and connect to another rotary RTO equipment.

[0012] Preferably, an air supply pipe is installed on the outer wall of the air supply assembly, and the air supply assembly is connected to the equipment body through the air supply pipe. Oil pipes are symmetrically installed on both sides of the air supply assembly, and both oil pipes are connected to a heating oil pipe. A heating pipe is installed in the inner wall of the air supply assembly, and the oil pipes are connected to the heating pipes. One oil pipe is used to input oil from the heating pipe into the heating oil pipe, and the other oil pipe is used to input oil from the heating oil pipe into the heating pipe.

[0013] Preferably, there are three filter screens, and the sizes of the three filter screens are large, medium and small from the outside to the inside, and the three filter screens are used to filter the exhaust gas.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This rotary RTO equipment for treating chemical waste gas uses three filters to perform triple filtration of the chemical waste gas entering the gas delivery assembly cavity. This prevents impurities in the chemical waste gas from entering the inner cavity of the equipment body. The chemical waste gas can be treated through the burner, rotary valve and ceramic packing bed.

[0016] This rotary RTO equipment for treating chemical waste gas can detect the treated chemical waste gas through gas sensors. When the gas passes the test, the first gas pipe can be opened to allow it to be fed into the chimney and discharged through the exhaust pipe. If the gas fails the test, the second gas pipe on the other side can be opened to allow it to be fed back into the cavity of another rotary RTO equipment for further treatment. With the help of the exhaust fan, the chemical waste gas in the equipment can be drawn to the top for easy detection.

[0017] This rotary RTO equipment for treating chemical waste gas can heat the equipment itself during operation through a heating oil pipe. In conjunction with two other oil pipes, the heating oil can be circulated to preheat the chemical waste gas before it enters the gas delivery assembly. This improves the energy utilization rate of the equipment during operation. Attached Figure Description

An exhaust fan 10 is rotatably connected inside the cavity of the top seat 11. The servo motor 8 drives the exhaust fan 10 through a rotating shaft. A gas sensor 12 is installed at the center of the bottom of the detection component 7. A first gas pipe 13 and a second gas pipe 14 are symmetrically installed on both sides of the bottom of the detection component 7. A solenoid valve 15 is connected to the outer flange of the first gas pipe 13 and the second gas pipe 14. The first gas pipe 13 is connected to the exhaust pipe 19. A gas supply pipe 18 is installed on the outer wall of the gas supply component 9. The gas supply component 9 is connected to the equipment body 1 through the gas supply pipe 18. Oil pipes 16 are symmetrically installed on both sides of the gas supply component 9. Both oil pipes 16 are connected to the heating oil pipe 5. A heating pipe is installed in the inner wall of the gas supply component 9. The oil pipes 16 are connected to the heating pipe. One oil pipe 16 is used to input the oil in the heating pipe to the heating oil pipe 5. The other oil pipe 16 is used to input the oil in the heating oil pipe 5 to the heating pipe. There are three filter screens 17. The sizes of the three filter screens 17 from the outside to the inside are large, medium and small. The three filter screens 17 are used to filter the exhaust gas.

[0025] Gas sensor 12 includes one of the following: electrochemical gas sensor, catalytic combustion gas sensor, semiconductor gas sensor, and infrared gas sensor. The sensor is selected based on the composition of the waste gas emitted by the chemical plant, and the threshold for passing and failing the test is set by the user.

[0026] The chemical waste gas entering the gas delivery assembly 9 is triple-filtered through three filters 17, preventing impurities from entering the equipment body 1. The chemical waste gas is treated by the burner 2, rotary valve 4, and ceramic packing bed 6. The treated chemical waste gas is detected by the gas sensor 12. If the gas passes the test, it can be discharged through the exhaust pipe 19 to the chimney 20 by opening the first gas pipe 13.
