Description

[0002] A regenerative thermal incineration oxidizer, also known as a regenerative thermal oxidizer, is a device used to treat waste gas. The waste gas is first heated to a temperature close to the thermal oxidation temperature before entering the combustion chamber for thermal oxidation. The oxidized gas temperature rises, and organic matter is essentially converted into carbon dioxide and water. The purified gas temperature drops, and it can be discharged once it meets emission standards.

[0003] At present, traditional regenerative thermal oxidation furnaces usually use natural gas as energy and are equipped with a burner head and a gas valve group. The natural gas is transported to the burner head through the gas valve group for combustion, thereby raising the temperature inside the furnace body to facilitate the treatment of the exhaust gas. In addition, during the process of treating the exhaust gas, combustion-supporting air needs to be introduced into the furnace body to improve the combustion efficiency of the natural gas.

[0004] However, when exhaust gas is treated in this manner, energy consumption will increase, carbon emissions will increase, and NOx will be generated, thereby affecting the environment. Utility Model Content

[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] Example 1:

[0036] The present application discloses an electrically heated thermal storage incineration oxidation furnace, referring to Figure 1 , comprising a furnace body 1 , in which an oxidation chamber is provided. A heating mechanism 2 is also installed on the furnace body 1 at the oxidation chamber, and the heating mechanism 2 is used to increase the temperature inside the furnace body 1 .

[0037] Reference Figure 2 and Figure 3The heating mechanism 2 comprises a heating assembly 21 and a wiring assembly 22. The heating assembly 21 comprises silicon-carbon rods 211 and insulating sleeves 212. A plurality of mutually symmetrical mounting holes are formed in the side walls of the furnace body 1 on both sides in the length direction of the furnace body 1, and the mounting holes penetrate the side walls of the furnace body 1. Two groups of insulating sleeves 212 are arranged on both sides in the length direction of the furnace body 1, and the two groups of insulating sleeves 212 on both sides of the furnace body 1 are mutually symmetrical. Each group of insulating sleeves 212 comprises a plurality of insulating sleeves 212. Each insulating sleeve 212 is mounted in a mounting hole along the axis direction of the mounting hole through a connecting piece, and the outer wall of the insulating sleeve 212 is attached to the inner wall of the mounting hole. One end of the insulating sleeve 212 is located outside the furnace body 1, and a folded edge 2121 is fixedly installed on the side wall of the one end of the insulating sleeve 212 located outside the furnace body 1. The diameter of the folded edge 2121 is greater than the diameter of the mounting hole, and a sealing gasket is further fixedly installed between the folded edge 2121 and the side wall of the furnace body 1.

[0038] With reference to Figure 2 and Figure 3 , a plurality of silicon-carbon rods 211 are arranged, and the plurality of silicon-carbon rods 211 correspond one-to-one to the plurality of mounting holes on one side in the length direction of the furnace body 1. One end of the silicon-carbon rod 211 is inserted into the insulating sleeve 212 on one side of the furnace body 1 along the length direction of the mounting hole, and penetrates the furnace body 1 and comes out of the insulating sleeve 212 on the other side of the furnace body 1. Both ends of the silicon-carbon rod 211 extend out of the furnace body 1, and the diameter of the silicon-carbon rod 211 is smaller than the diameter of the inner ring of the insulating sleeve 212. A gap between the silicon-carbon rod 211 and the insulating sleeve 212 is filled with a heat preservation material. The heat preservation material is used to support the silicon-carbon rod 211. The heat preservation material is selected from ceramic fiber materials, which is a prior art and will not be described here.

[0039] With reference to Figure 3 and Figure 4 , the connecting piece comprises a connecting flange 213 and a positioning pin 214. A plurality of connecting flanges 213 are arranged, and the plurality of connecting flanges 213 correspond one-to-one to the plurality of insulating sleeves 212. The connecting flange 213 is sleeved on the one end of the silicon-carbon rod 211 located outside the furnace body 1. A sealing gasket is also installed between the connecting flange 213 and the folded edge 2121 of the insulating sleeve 212. The connecting flange 213 presses the sealing gasket against the folded edge 2121 of the insulating sleeve 212. The positioning pin 214 penetrates the connecting flange 213 and is detachably connected with the side wall of the furnace body 1.

[0040] With reference to Figure 4The wiring assembly 22 comprises a positioning clamp 221 and a wire 222, one end of the wire 222 is connected with an external power supply, and the other end is wound around the end of the plurality of silicon-carbon rods 211, so that the plurality of silicon-carbon rods 211 are connected in series. The specific connection mode of the wire 222 with the silicon-carbon rods 211 and the mode in which the external power supply raises the temperature in the furnace body 1 through the wire 222 are the prior art in the field, and will not be described here. The positioning clamp 221 is detachably mounted on the end of the silicon-carbon rod 211, and the positioning clamp 221 is used to position the wire 222 on the silicon-carbon rod 211.

[0041] With reference to Figure 1 and Figure 4 , a pressure stabilizing assembly 23 is also mounted on the side wall of the furnace body 1 at the end of the silicon-carbon rod 211, the pressure stabilizing assembly 23 comprises a pressure stabilizing cover 231 and a pressure stabilizing pipe 232, the pressure stabilizing cover 231 is detachably mounted on the side wall of the furnace body 1, and the pressure stabilizing cover 231 covers the end of the silicon-carbon rod 211 located in the furnace body 1. One end of the pressure stabilizing pipe 232 is mounted on the pressure stabilizing cover 231, and the pressure stabilizing pipe 232 communicates with the space in the pressure stabilizing cover 231. The other end of the pressure stabilizing pipe 232 is connected with an external air source, and the external air source introduces compressed air into the pressure stabilizing cover 231 through the pressure stabilizing pipe 232, so that when the gas in the furnace body 1 escapes from the gap between the silicon-carbon rod 211 and the connecting flange 213, the pressure at the end of the silicon-carbon rod 211 located outside the furnace body 1 is kept the same as the pressure at the part of the silicon-carbon rod 211 located in the furnace body 1, so as to facilitate the force balance of the silicon-carbon rod 211, thereby reducing the escape of gas, and also avoiding the temperature in the pressure stabilizing cover 231 being too high.

[0042] The working principle of the embodiment of the present application is that the external power supply is used to pass current to the silicon-carbon rod 211 through the wire 222, so that the silicon-carbon rod 211 raises the temperature in the furnace body 1, so that the temperature of the oxidation chamber in the furnace body 1 reaches the working temperature, and at the same time when the silicon-carbon rod 211 works, if there is a pressure difference between the end of the silicon-carbon rod 211 located outside the furnace body 1 and the end of the silicon-carbon rod 211 located in the furnace body 1, the external air source introduces compressed air into the pressure stabilizing cover 231 or extracts air in the pressure stabilizing cover 231 through the pressure stabilizing pipe 232, so that the pressure at the end of the silicon-carbon rod 211 located in the pressure stabilizing cover 231 is the same as the pressure at the part of the silicon-carbon rod 211 located in the furnace body 1, so as to keep the force balance of the silicon-carbon rod 211, thereby facilitating the extension of the service life of the silicon-carbon rod 211.

[0043] When the silicon-carbon rod 211 on the furnace body 1 is worn out, the positioning pin 214 is pulled out of the furnace body 1, so that the connecting flange 213 is disassembled, thereby releasing the limiting of the connecting flange 213 on the insulating sleeve 212 and the silicon-carbon rod 211, thereby facilitating the disassembly and replacement of the silicon-carbon rod 211.

[0044] Embodiment two:

[0045] With reference to Figure 5 and Figure 6 The difference between the embodiment and the embodiment one is that the side wall of the furnace body 1 is provided with a slot 11 for inserting the positioning pin 214, the cross section of the slot 11 is circular, the diameter of the opening position of the slot 11 on the side wall of the furnace body 1 is smaller than the diameter of the inside of the slot 11, and the diameter of the positioning pin 214 is smaller than the diameter of the opening of the slot 11. The end of the positioning pin 214 in the slot 11 is also provided with a locking piece, the locking piece includes a locking block 215 and a locking spring 217, the side wall of the end of the positioning pin 214 on the side wall of the furnace body 1 is provided with a mounting groove 2141, the mounting groove 2141 is arranged along the axis direction of the positioning pin 214, one end of the locking block 215 is rotatably mounted in the mounting groove 2141 and is located at the end of the positioning pin 214 on the side wall of the furnace body 1, the other end of the locking block 215 extends outwardly of the furnace body 1 and is inclined away from the axis of the positioning pin 214, the locking block 215 is used for being inserted into the slot 11, and the end of the locking block 215 close to the opening position of the slot 11 is used for abutting against the inner wall of the opening of the slot 11, the locking spring 217 is also mounted in the mounting groove 2141 and is located between the groove bottom wall of the mounting groove 2141 and the locking block 215, one end of the locking spring 217 is fixedly connected with the inner wall of the mounting groove 2141, and the other end of the locking spring 217 extends toward the locking block 215 and abuts against the side wall of the locking block 215.

[0046] With reference to Figure 5 and Figure 6 The inner wall of the opening of the slot 11 on the furnace body 1 is fixedly provided with an unlocking block 216, the side wall of the side close to the opening of the unlocking block 216 is provided with a guide arc surface 2161, the guide arc surface 2161 is arranged along the circumferential direction of the opening, one end of the guide arc surface 2161 extends to coincide with the side wall of the opening of the slot 11, and the other end of the guide arc surface 2161 extends away from the opening of the slot 11.

[0047] The working principle of the embodiment of the present application is as follows: after the insulating sleeve 212 and the silicon carbide rod 211 are installed on the furnace body 1, the sealing gasket is placed on the silicon carbide rod 211 so that the sealing gasket contacts the side wall of the folded edge 2121 at the end of the insulating sleeve 212, and then the connecting flange 213 is placed on the silicon carbide rod 211 so that the side wall of the connecting flange 213 contacts the side wall of the sealing gasket, and then the positioning pin 214 is passed through the connecting flange 213 and inserted into the slot 11 on the side wall of the furnace body 1. When the end of the positioning pin 214 just contacts the side wall of the opening of the slot 11, the side wall of the opening of the slot 11 contacts the side wall of the locking block 215, thereby pushing the locking block 215 into the installation groove 2141 and compressing the locking spring 217, so that the side wall of the locking block 215 slides along the side wall of the opening of the slot 11 until the positioning pin 214 drives the locking block 215 to be fully inserted into the slot 11 and rotates a certain angle so that the locking block 215 is away from the unlocking block 216. At this time, the lock The side wall of the fixing block 215 is separated from the side wall of the opening of the slot 11, and the locking block 215 is also separated from the unlocking block 216, so that one end of the locking block 215 rotates in the direction away from the mounting slot 2141 under the action of the locking spring 217, so that one end of the locking block 215 extends out of the mounting slot 2141, so that the side wall of the end of the locking block 215 located outside the mounting slot 2141 contacts the inner wall of the opening of the slot 11, thereby positioning the positioning pin 214 in the slot 11.

[0048] When the connecting flange 213 needs to be removed, the positioning pin 214 is rotated, causing the positioning pin 214 to drive the locking block 215 to rotate, so that the side wall of the locking block 215 located outside the installation slot 2141 gradually moves to contact the guide arc 2161 of the unlocking block 216, causing the side wall of the locking block 215 to slide along the guide arc 2161. As the positioning pin 214 rotates, the locking block 215 is gradually pushed into the installation slot 2141 by the guide arc 2161 of the unlocking block 216, causing the locking block 215 to compress the locking spring 217. When the locking block 215 slides along the guide arc 2161 until the guide arc 2161 coincides with the opening of the slot 11, the locking block 215 is completely retracted into the installation slot 2141. At this time, the locking block 215 is located within the opening of the slot 11, allowing the positioning pin 214 to be pulled out of the slot 11, thereby completing the removal of the connecting flange 213.

[0049] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
