Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to an energy-saving vertical RTO waste gas treatment device. Background Art

[0002] With the rapid development of industry, the pollution problem of waste gas emissions to the environment is becoming increasingly serious. In order to effectively treat these waste gases, various waste gas treatment devices have emerged. Among them, the vertical rotary RTO waste gas treatment device has been widely used in the industrial field due to its efficient organic waste gas treatment capacity and energy-saving characteristics.

[0003] Deficiencies of existing technology:

[0004] At present, the common RTO waste gas treatment device usually includes key components such as a shell, an intake pipe, an exhaust pipe, a rotary valve, a ceramic heat storage body and a combustion chamber. In the actual working process, the exhaust gas enters the device through the intake pipe, and under the control of the rotary valve, alternately enters the ceramic heat storage body for preheating, and then enters the combustion chamber for high-temperature combustion to oxidize and decompose the harmful substances in the exhaust gas into harmless substances. The high-temperature gas after combustion passes through the ceramic heat storage body again for heat recovery and is finally discharged through the exhaust pipe. However, there is a significant problem in the treatment process of the existing RTO waste gas treatment device. When the exhaust gas is burned, water will be generated. This water will be mixed with the newly generated gas and discharged downward through the ceramic heat storage body. Because there are multiple small airways with complex structures inside the ceramic heat storage body, water is easy to remain inside it. After long-term accumulation, it will block the airway and seriously affect the smooth flow of air. In addition, when these waters flow through the exhaust pipe, rotary valve and other equipment at the terminal, they will cause rust to the equipment, which will not only affect the normal operation of the equipment, but also shorten the service life of the equipment.

[0032] See also Figure 1-6As shown, the utility model provides a technical solution of an energy-saving vertical RTO waste gas treatment device: an energy-saving vertical RTO waste gas treatment device, comprising a shell 1 and an air intake pipe 2 and an exhaust pipe 3 connected to both sides of the air cavity at the lower end of the shell 1, a rotary valve 4 is rotatably connected above the exhaust pipe 3 in the air cavity at the lower end of the shell 1, a driving part 5 is installed at the lower end of the shell 1, a transmission shaft 6 penetrating the shell 1 is installed at the upper end of the driving part 5 for driving the rotary valve 4 to rotate, a ceramic heat storage body 7 is fixedly installed at the upper end of the rotary valve 4 inside the shell 1, the shell 1, the exhaust pipe 3 and the ceramic heat storage body 7 are all rotatably connected to the transmission shaft 6, an air intake and exhaust assembly 8 is installed inside the shell 1 above the ceramic heat storage body 7, and a drainage assembly 9 is installed at the lower end of the air intake and exhaust assembly 8. The air intake and exhaust assembly 8 includes a rotating air guide frame 801 and a guide plate 804. The rotating air guide frame 801 is rotatably mounted in the mounting groove on the inner wall of the shell 1 and is located above the ceramic heat storage body 7. The rotating air guide frame 801 is connected to the transmission shaft 6. The rotating air guide frame 801 rotates synchronously with the rotary valve 4. The two sides of the rotating air guide frame 801 are symmetrically provided with an air inlet 802 and an exhaust duct 803. The air inlet duct 802 and the exhaust duct 803 are respectively maintained above the exhaust port and the air inlet of the rotary valve 4. The guide plate 804 is fixedly installed on the inner wall of the exhaust duct 803 at an angle to guide the moving path of the airflow. The water collection area below the upper inclined guide plate 804 should be opened for drainage. A liquid collecting plate 805 is fixedly installed on the inner wall of the exhaust duct 803 at the lower side of the lowermost air outlet of the guide plate 804. When the RTO exhaust gas treatment device starts to work, the driving part 5 is started first. The driving part 5 drives the rotary valve 4 and the rotary air guide frame 801 to rotate through the transmission shaft 6. The external RTO exhaust gas is input into the air cavity at the lower end of the shell 1 through the intake pipe 2, and then enters the rotary valve 4 from the air holes on the side wall of the rotary valve 4 and is discharged upward into the ceramic heat storage body 7. Then the exhaust gas continues to move upward through the intake duct 802 and enters the combustion chamber for combustion. Since the air pressure in the exhaust duct 803 is lower than that in the inlet duct 802, the burned gas mixed with water droplets is discharged into the exhaust duct 803, and the gas flows along the guide plate 804 in the exhaust duct 803. During the gas flow, the water droplets mixed in the gas condense and separate from the gas after contacting the guide plate 804. As the water droplets gather, a water flow is slowly formed, which flows downward along the guide plate 804 under the action of gravity and converges into the liquid collecting plate 805. After the gas is dried, it is discharged from the bottom of the exhaust duct 803 into the ceramic heat storage body 7, and finally passes through the ceramic heat storage body 7 and enters the exhaust pipe 3 through the rotary valve 4 for discharge. In this process, the rotary valve 4 and the rotary air guide frame 801 always rotate synchronously to ensure that the inlet duct 802 and the exhaust duct 803 of the rotary air guide frame 801 are kept corresponding to the exhaust port and the air inlet of the rotary valve 4.Through the air intake and exhaust assembly 8, the water generated by the combustion of the RTO exhaust gas is separated from the gas and then enters the ceramic heat storage body 7, thereby ensuring the dryness of the ceramic heat storage body 7, avoiding blockage of the airway in the ceramic heat storage body 7, making the overall circulation of the gas smoother, and also avoiding the corrosion of the terminal pipes and equipment of the entire exhaust gas treatment device by water, thereby improving the stability and service life of the equipment.

[0033] The drainage assembly 9 includes a first drainage hole 901, a water guide plate 905 and an electromagnet 907. The first drainage hole 901 is provided on the main body of the rotating air guide frame 801 and is located inside the liquid collecting plate 805. A sealing plug 902 is movably installed on one side of the first drainage hole 901. The other end of the sealing plug 902 passes through the first drainage hole 901 and is fixedly installed with a permanent magnet 903. The permanent magnet 903 is a high temperature resistant aluminum nickel cobalt magnet. A reset spring 904 is connected to the permanent magnet 903 and the side of the first drainage hole 901 away from the sealing plug 902. The water guide plate 905 is installed below the side of the first drainage hole 901 away from the sealing plug 902 to guide the water flowing out of the first drainage hole 901. A water trough 906 is provided on one side of the inner wall of the housing 1. The water trough 906 is located below the moving path of the water outlet of the water guide plate 905. The electromagnet 907 is fixedly installed on the inner wall of the housing 1 and is located above the water trough 906. The height of the electromagnet 907 is consistent with that of the permanent magnet 903. When the device is treating waste gas, the electromagnet 907 remains energized, the rotating air guide frame 801 rotates along the transmission shaft 6 in the housing 1, and the water generated by the combustion of the waste gas gradually accumulates in the liquid collecting plate 805. When the permanent magnet 903 passes through the inner side of the electromagnet 907, the electromagnet 907 generates a repulsive force on the permanent magnet 903. At this time, the permanent magnet 903 drives the sealing plug 902 to overcome the elastic force of the return spring 904 and move to one side of the first drainage hole 901. At this time, the first drainage hole 901 is opened, and the water in the liquid collecting plate 805 is discharged through the first drainage hole 901 and flows into the water tank 906 along the water guide plate 905. When the permanent magnet 903 leaves the electromagnet 907, the repulsive force of the electromagnet 907 is lost, the return spring 904 drives the sealing plug 902 to reset, and the first drainage hole 901 is closed. With the rotation of the rotating air guide frame 801, the liquid collecting plate 805 can be regularly intermittently drained. Through the drainage component 9, the effect of draining the accumulated water out of the rotating air guide frame 801 is achieved, avoiding overflow with the accumulation of waste water in the later stage, and short-term, intermittent drainage can not only meet the drainage demand, but also avoid a large amount of gas from leaking through the first drainage hole 901.

[0034] A plurality of second drainage holes 10 are provided in the water tank 906 , and the second drainage holes 10 can facilitate rapid drainage of the accumulated water in the water tank 906 .

[0035] A water storage barrel 11 is installed on the outer wall of the shell 1 below the second drain hole 10 , and the water storage barrel 11 is used to receive waste water discharged from the water tank 906 outside the shell 1 .

[0036] The length of the electromagnet 907 is smaller than that of the water tank 906 , so that when the permanent magnet 903 moves to the inner side of the electromagnet 907 , the lower water outlet of the water guide plate 905 is located above the water tank 906 , thereby preventing waste water from flowing out of the water tank 906 .

[0037] The rotating air guide frame 801 is made of ceramic material. The ceramic material has excellent high temperature resistance and corrosion resistance and can effectively increase the service life of the rotating air guide frame 801.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
