[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the change in the total standard Gibbs free energy of the reaction. It can also be described as a substance that can increase the chemical reaction rate without changing the chemical equilibrium in a chemical reaction, and its own mass and chemical properties do not change before and after the chemical reaction. Thermal oil is a heat carrier oil with good heat transfer efficiency, fast heat dissipation, and excellent thermal stability. Using thermal oil to transfer heat energy to the catalyst is one of the means to achieve catalyst activation.

[0003] At present, the thermal oil electric heater needs to ensure the sealing of the oil pipeline when it is working. If the oil pipeline of the thermal oil electric heater is too long, it is easy to malfunction or the oil pipeline needs to be cleaned. It is often necessary to stop the electric heater and take out the oil pipeline for maintenance and cleaning.

[0021] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a thermal oil electric heater includes a heater main body 1, an oil outlet pipe 2 and an oil return pipe 3. An oil outlet pipe 2 and an oil return pipe 3 are provided on one side of the heater main body 1. The oil outlet pipe 2 is located in front of the oil return pipe 3. Two oil distribution pipes 5 are mirror-imaged on one side of the oil outlet pipe 2 and the oil return pipe 3. The two oil distribution pipes 5 close to the side of the heater main body 1 are fixedly connected to the oil outlet pipe 2 and the oil return pipe 3 through flanges respectively. An oil delivery pipe 4 is provided between every two opposite oil distribution pipes 5 on the left and right. Control valves 6 are provided between both ends of each oil delivery pipe 4 and the corresponding two oil distribution pipes 5. Both ends of each control valve 6 are fixedly connected to the oil distribution pipe 5 and the oil delivery pipe 4 through flanges respectively, so that the heater main body 1 has multiple oil delivery pipes 4 for oil delivery.

[0023] Specifically, the diameter of the oil distribution pipe 5 is equal to the diameter of the oil delivery pipe 4, the shape of the oil distribution pipe 5 is a "Y"-shaped fork, and the height between the forks of the oil distribution pipe 5 is equal to the height of the two oil delivery pipes 4, making the installation of the oil delivery pipe 4 more convenient.

[0024] As an optimization solution, Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a fixed bracket 8 is provided below the oil distribution pipe 5, and a fixed plate 9 is symmetrically fixed to the top of the fixed bracket 8. The bottom end of each oil distribution pipe 5 is placed inside the fixed plate 9. A partition 10 is provided inside the fixed bracket 8, and four oil collecting plates 11 are symmetrically fixed on both sides of the partition 10. Removable oil collecting boxes 7 are provided on both sides below the partition 10, so that the heat transfer oil remaining in the oil pipeline 4 can be recovered.

[0025] Specifically, the shape of the top of the fixed bracket 8 is an inclined surface that matches the shape of the oil distribution pipe 5. The height of the fixed plate 9 is greater than the height of the inner circle of the oil distribution pipe 5, so that the oil distribution pipe 5 is fixed. The height of the partition 10 is equal to the height of the top of the oil distribution pipe 5. A fixing block 12 is fixed on the partition 10. A fixing groove that matches the shape of the oil collecting plate 11 is opened on the partition 10. The top surface of the oil collecting plate 11 is an inclined surface inclined toward the side of the partition 10. The oil collecting plate 11 is engaged with the partition 10 through the fixing groove and the fixing block 12, so that the oil collecting plate 11 recovers the heat transfer oil into the oil collecting tank 7. The length of the oil collecting tank 7 is greater than the length of the oil collecting plate 11. A card slot that matches the shape of the oil collecting tank 7 is opened at the bottom of the partition 10. The side of the oil collecting tank 7 close to the partition 10 is flush with the partition 10 to avoid heat transfer oil remaining at the top of the oil collecting tank 7.

[0026] Working principle: When the heater main body 1 is working, when an oil pipeline 4 is damaged or needs to be cleaned, first turn the control valve 6 on the output end to allow the residual heat-conducting oil in the oil pipeline 4 to flow out, and then turn the control valve 6 on the output end to connect and close the two oil branch pipes 5 on the corresponding oil pipeline 4, disconnect the corresponding oil pipeline 4 from the control valves 6 at both ends of the oil pipeline 4, remove the oil pipeline 4, and at the same time, the heat-conducting oil remaining on the oil pipeline 4 and the control valves 6 at both ends falls onto the oil collecting plate 11, and under the action of gravity, the heat-conducting oil falls into the oil collecting tank 7, and a new oil pipeline 4 is replaced and installed on the two control valves 6. At this time, turn the control valve 6, and the two oil branch pipes 5 on the corresponding oil pipeline 4 are restored to connection, and then the removed oil pipeline 4 is repaired and cleaned, and the oil collecting tank 7 is taken out from under the partition 10 for recycling.
