Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] A specific embodiment of this utility model provides an electric RTO with a side-mounted electric heater, such as... Figure 1-3 As shown, it mainly includes an RTO body 1 and an electric heater. The electric heater is nested inside the RTO body, and at least one electric heater is provided. The RTO body 1 includes an oxidation chamber 2 and a heat storage chamber 3. The oxidation chamber 2 is located on top of the heat storage chamber 3. The electric heater includes a fixed shell 4, a temperature control box 5, a heat dissipation device 6, a heat insulation layer 7, a heating chamber 8, and a heating tube 9. The fixed shell 4 is located outside the heat insulation layer 7 and the heating chamber 8. The heat insulation layer 7 is connected to the heating chamber 8 and the heat dissipation device 6 on both sides, respectively. The temperature control box 5 is located on the opposite side of the side where the heat dissipation device 6 is connected to the heat insulation layer 7. The heating tube 9 is provided inside the heating chamber 8.
[0027] Specifically, such as Figure 1 As shown, the temperature control box 5, heat dissipation device 6, and heating chamber 8 of the electric heating box are arranged in a straight line. Heating tubes 9 are installed in the heating chamber 8. The tube body of a single heating tube 9 is set vertically. The heating tube 9 is set in a U-shaped tube. Several heating tubes 9 form a heating tube group. The heating tube group is equipped with a heating head. The heating head and the tube body of the heating tube 9 are set at a 90° angle. The heating head is connected to the side of the heating chamber 8. The heating tube group is placed horizontally in the heating chamber 8 to avoid the heating head falling off due to high temperature.
[0028] The heat dissipation device 6 includes several heat sinks 61 and several heat dissipation rods 62. The heat sinks 61 are evenly fixed on the heat dissipation rods 62. One end of the heat dissipation rod 62 passes through the heat insulation layer 7 and connects to the heating chamber 8, and helps the heating chamber 8 dissipate heat by conducting heat. The temperature control box 5 is located on the outermost side, and the temperature and on / off of the heating tube 9 are controlled by the control element inside the temperature control box 5.
[0029] Specifically, an electric heater mounting slot 10 is provided on the side of the RTO body 1, and a heat insulation layer 7 is fixed at the slot opening. A fixed outer shell 4 can be placed inside the electric heater mounting slot 10, and a heating chamber 8 is provided inside the fixed outer shell 4. A heat dissipation device 6 and a temperature control box 5 are connected to the outside of the slot opening.
[0030] Example 1, as Figure 3 As shown, the two-tower RTO includes a first oxidation chamber A, a second oxidation chamber B, a heat storage chamber 4, an electric heater, and a valve system. The electric heater is arranged between the first oxidation chamber A and the second oxidation chamber B. The electric heater is side-mounted, and the heat storage chamber 3 is lined with ceramic heat storage material, which makes the thermal efficiency of the RTO body 1 higher. The electric heater is side-mounted and is arranged on the side of the upper chamber. It provides heat to the RTO through the electric heating tube 9. The waste gas passes through the surface of the electric heating tube 9 and undergoes convective heat exchange. The electric heating tube 9 converts electrical energy into the heat energy required to oxidize the waste gas, which greatly reduces waste gas emissions.
[0031] Example 2, as Figure 4-6 As shown, the three-tower RTO includes a first oxidation chamber A, a second oxidation chamber B, a third oxidation chamber C, a regenerator 4, electric heaters, and a valve system. The electric heaters can be arranged in various ways, including a side-mounted configuration where the electric heaters are located on the side of the upper chamber. Figure 4 As shown, the electric heater is positioned between the first oxidation chamber A and the second oxidation chamber B, ensuring that the exhaust gas within the entire oxidation chamber is heated uniformly. Figure 5 As shown, the electric heaters are arranged between the first oxidation chamber A, the second oxidation chamber B, and the third oxidation chamber C. The two electric heaters ensure that the exhaust gas within the entire oxidation chamber is heated uniformly. Figure 6 As shown, the electric heaters are arranged between the first oxidation chamber A, the second oxidation chamber B, and the third oxidation chamber C. The three electric heaters ensure that the exhaust gas in the entire oxidation chamber can be heated evenly.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
