[0002] A regenerative thermal incinerator, also known as a regenerative oxidation furnace, is a highly efficient organic waste gas treatment equipment. Traditional regenerative thermal incinerators usually use natural gas as energy, require the installation of a burner head and a gas valve group, and also require the introduction of combustion-supporting air, which easily increases carbon emissions and nitrogen oxide emissions.

Generally, the electric heater includes a heating wire and a frame, and the heating wire is mounted on the frame through a number of insulating rings made of insulating materials such as ceramics, and then the temperature in the incinerator is controlled by energizing the heating wire.

[0044] Reference Figure 3 and Figure 4 When the heating wire 51 needs to be installed on the mounting plate 53, the detachable half ring 524 is put on the heating wire 51, and then the positioning half ring 521 is rotated to insert the positioning block 522 on the positioning half ring 521 into the positioning groove 525 of the detachable half ring 524, so that the positioning half ring 521 and the detachable half ring 524 form a circular ring covering the heating wire 51, and the through hole 526 is aligned with the connecting hole 523. Figure 4 and Figure 6Then, the quick release sleeve 541 is inserted from one end of the through hole 526, passes through the connection hole 523 on the positioning block 522, and then extends from the other end of the through hole 526, so that the insulating ring 52 is located between the limiting hole on the quick release sleeve 541 and the limiting ring 545. Then, the quick release sleeve 541 is kept stationary and the positioning rod 543 is rotated to move the positioning rod 543 into the quick release sleeve 541, so that the positioning rod 543 pushes the push rod 544 to move toward the locking rod 542, so that the push rod 544 drives the extrusion rod 546 to contact the end of the locking rod, and the end of the locking rod 542 close to the extrusion rod 546 slides along the tapered inclined surface of the extrusion rod 546, so that the end of the locking rod 542 away from the extrusion rod 546 extends out of the limiting hole, so that the side wall of the ball head of the locking rod 542 contacts the side wall of the detachable half ring 524. Finally, the quick release sleeve 541 is kept stationary, and the limiting ring 545 is rotated to move the limiting ring 545 along the axis direction of the quick release sleeve 541 toward the detachable half ring 524, so that the side wall of the limiting ring 545 abuts against the side wall of the detachable half ring 524 away from the locking rod 542, so that the quick release sleeve 541 is positioned and installed on the detachable half ring 524 through the locking rod 542 and the limiting ring 545, thereby maintaining the connection between the detachable half ring 524 and the positioning half ring 521. Figure 3 and Figure 4 Finally, the insulating ring 52 is placed in the mounting groove 531 of the mounting plate 53 , and the cover plate 532 is installed on the mounting plate 53 , so as to limit the insulating ring 52 .

[0045] Reference Figure 3 and Figure 4 When the insulating ring 52 needs to be replaced, first push the insulating ring 52 out of the mounting groove 531 along the axial direction of the heating wire 51. Figure 4 and Figure 6Then, by keeping the quick release sleeve 541 stationary and rotating the positioning rod 543, the positioning rod 543 is moved along the axis of the quick release sleeve 541 in the direction away from the quick release sleeve 541, thereby driving the push rod 544 to move in the direction away from the locking rod 542, so that the push rod 544 drives the extrusion rod 546 to move in the direction away from the locking rod 542, so that the side wall of the extrusion rod 546 is separated from the end of the locking rod 542 located in the quick release sleeve 541, and then pulling the end of the quick release sleeve 541 equipped with the limiting ring 545, so that the quick release sleeve 541 drives the locking rod 542 to hit the side wall of the detachable half ring 524, so that the spherical surface of the end of the locking rod 542 located outside the quick release sleeve 541 is squeezed by the side wall of the detachable half ring 524, so that the locking rod 542 is retracted into the limiting hole again, so that the end of the locking rod 542 located in the quick release sleeve 541 hits the side wall of the extrusion rod 546 again. At this time, the end of the locking rod 542 is separated from the side wall of the removable half ring 524, so that the quick-release sleeve 541 can be smoothly separated from the removable half ring 524. Finally, the removable half ring 524 is rotated to separate the removable half ring 524 from the positioning half ring 521, thereby realizing the action of removing the insulating ring 52 from the heating wire 51.

The probe 7 passes through the bottom wall of the junction box 21 and passes through the heat sink 31 and the heat insulation box 41 in sequence, and the end of the probe 7 away from the junction box 21 extends to the heating wire 51. The temperature sensor monitors the temperature of the heating wire 51 through the probe 7, thereby facilitating the adjustment of the power supplied to the electric heater, thereby adjusting the working efficiency of the electric heater.

[0048] The working principle of the embodiment of the present application is as follows: the electric heater is vertically hoisted into the thermal storage incinerator, so that the heat dissipation module 3 and the junction box 21 are kept outside the thermal storage incinerator, and the heat insulation box 41 and the heating module 5 are located inside the furnace body, and the heat insulation box 41 cooperates with the heat insulation material in the furnace body to insulate the thermal storage incinerator. Then, by connecting the junction box 21 to the external power supply through a cable, the heating wire 51 is powered, thereby raising the temperature inside the thermal storage incinerator to reach the working temperature.

[0049] When the insulating ring 52 of the electric heater is worn out after being used for a period of time, the electric heater needs to be taken out of the thermal storage incinerator for maintenance and repair, and the insulating ring 52 is disassembled and replaced by the quick-release mechanism 54. After the insulating ring 52 is replaced, the electric heater is reinstalled in the thermal storage incinerator to facilitate the continuous operation of the thermal storage incinerator.
