Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment devices, and in particular to an energy-saving and environment-friendly RTO device for producing dipped cord fabrics. Background Art

[0002] In the production process of dipped cord fabric, in order to enhance the physical properties of the cord fabric, the cord fabric needs to be immersed in an adhesive, and the organic solvent in the adhesive will evaporate in the process to form waste gas. At the same time, the cord fabric after dipping needs to be dried to remove excess moisture and solvent. During the drying process, volatile organic compounds and other harmful substances will be discharged along with the hot air.

[0003] For waste gas containing volatile organic compounds, RTO devices are usually used for treatment. RTO devices convert harmful substances in waste gas into carbon dioxide and water through high-temperature oxidation, and use heat storage bodies (usually honeycomb ceramics) to store and recover heat. Compared with traditional catalytic combustion and direct-fired oxidation furnaces, RTO significantly reduces energy consumption and greenhouse gas emissions through efficient heat recovery.

[0004] During the use of the current regenerative incinerator, the exhaust gas is first preheated through the regenerative body. During this process, some of the solid impurities contained in the exhaust gas will adhere to the through holes of the regenerative body. At the same time, the solid impurities generated during the incineration of the exhaust gas will also fall into the through holes of the regenerative body, thereby reducing the flow area of ​​the through holes of the regenerative body. The existing regenerative incinerator will perform a recoil operation on the regenerative body during use to remove impurities in the regenerative body, but the main purpose of this recoil operation is to remove the exhaust gas remaining in the regenerative body. Although some impurities in the regenerative body can be removed when cleaning the exhaust gas, the impurities blown out by the gas will still fall back on the regenerative body, and re-enter or even adhere to the through holes of the regenerative body, affecting the flow area of ​​the regenerative body and even blocking the through holes of the regenerative body.

In the initial position, the through holes on the sealing plate 37 are connected to the adjacent through holes on the adjacent air guide shells 36. The upper sides of the heat storage body 35 and the sealing plate 37 are provided with matrix-distributed quadrangular pyramids. The adjacent quadrangular pyramids fit each other, and the upper parts of the heat storage body 35 and the sealing plate 37 are provided with annularly distributed inclined surfaces. The bottoms of the quadrangular pyramids are lower than the upper sides of the adjacent inclined surfaces, which are used to guide impurities on the upper sides of the heat storage body 35 and the sealing plate 37, so that the solid impurities in the processing box 31 are moved to the through holes of the heat storage body 35 for subsequent cleaning. A cleaning mechanism is provided on the processing box 31, and the cleaning mechanism is used to clean the through holes of the heat storage body 35 in a linear array.

[0023] like Figure 3-Figure 6As shown, a fixing rod 38 is fixedly connected to the front portion of the upper side of the blocking plate 37, and the three fixing rods 38 all penetrate the processing box 31 and are slidably connected thereto. Three first electric push rods 39 in a linear array are installed in the middle portion of the front side of the processing box 31, and the first electric push rods 39 are connected to the remote control terminal network.

[0024] like Figure 1-Figure 5 As shown, the cleaning mechanism includes two groups of cleaning tubes 40 symmetrically distributed front to back, the two groups of cleaning tubes 40 are fixedly connected to the outside of the processing box 31, each group of cleaning tubes 40 is set to two symmetrically distributed in the center, and four air pumps distributed in a matrix are installed on the outside of the processing box 31. The four cleaning tubes 40 are respectively connected to the output ends of adjacent air pumps, and clean air is respectively introduced into the four cleaning tubes 40 by the four air pumps. The opposite sides of each group of cleaning tubes 40 are fixedly connected and connected with three guide tubes 41 in a linear array. The guide tubes 41 on two adjacent cleaning tubes 40 are staggered. The guide tubes 41 pass through the processing box 31 and are connected to adjacent cavities on adjacent air guide shells 36. The air pump transmits the clean air through the adjacent cleaning tubes 40 and the three adjacent guide tubes 41 to pass the clean air into the adjacent cavities on the air guide shell 36, and the impurities in the through holes of the adjacent heat storage body 35 are blown to Blowing downward, and the guide tube 41 is provided with a solenoid valve connected to the remote control terminal network (it is an existing device, not shown in the figure), and a pressure detector connected to the remote control terminal network is installed inside the guide tube 41, which is used to detect the resistance of air when flowing into the through hole of the heat storage body 35, and then judge the fluidity of the through hole of the heat storage body 35. The upper side of the air intake pipe 32 is fixedly connected and connected with a linear array of diverter pipes 42, and the three chambers of the treatment box 31 are respectively connected to the adjacent diverter pipes 42. The diverter pipes 42 are provided with solenoid valves connected to the remote control terminal network. The positions where the three chambers of the treatment box 31 are connected to the adjacent diverter pipes 42 are respectively located on the upper sides of the adjacent blocking plates 37, which are used to divert the exhaust gas in the air intake pipe 32. After the heat storage body 35 is blocked, the exhaust gas flows directly into the treatment box 31 through the diverter pipes 42.

[0025] like Figure 1-Figure 4 and Figure 7As shown, three conical shells 50 in a linear array are fixedly connected to the lower side of the processing box 31. The three chambers of the processing box 31 are respectively connected to the adjacent conical shells 50, which are used to guide and store solid impurities in the three chambers. The three conical shells 50 are all fixedly connected to the bottom frame 30. A receiving block 52 is fixedly connected to the lower side of the conical shell 50 to receive impurities dropped from the adjacent conical shells 50. An interception net is arranged on the upper side of the receiving block 52 to prevent the impurities dropped on the receiving block 52 from leaking outward. The receiving block 52 is fixedly connected to the bottom frame 30. The receiving block 52 is connected with a connecting rod in a through-type sliding manner. The connecting rod of the guiding block 52 is fixedly connected with a blocking block 51 which cooperates with the conical shell 50 for blocking. The upper side of the blocking block 51 is set to be conical for guiding impurities falling thereon. The lower side of the guiding block 52 is fixedly connected with a second electric push rod 53.

The telescopic end of the second electric push rod 53 drives the adjacent blocking blocks 51 to move synchronously through the transmission of the adjacent connecting rods to control the opening and closing of the lower ports of the adjacent conical shells 50.

[0026] When the device is used to treat the waste gas generated in the production process of the tire cord fabric, the induced draft fan is started by the remote control terminal to pass the waste gas generated in the production process of the tire cord fabric into the air inlet pipe 32, and the waste gas is preheated by the heat storage body 35 in the three chambers in turn, and the preheated waste gas is ignited in the combustion chamber at the same time. The opening and closing processes of the solenoid valves on the three chambers and the air inlet pipe 32, the exhaust pipe 33 and the backblowing pipe 34 can all refer to the use process of the existing heat storage incinerator, and will not be described in detail here.

[0027] In the process of exhaust gas combustion treatment, the solid impurities after exhaust gas combustion fall downward on the upper side of the three blocking plates 37, and are guided by the inclined surfaces on the upper sides of the three blocking plates 37 and the conical surfaces on the matrix distributed quadrangular pyramids, and flow into the through holes on the blocking plates 37, and flow downward along the through holes on the blocking plates 37 to the through holes of the adjacent heat storage body 35, and then fall downward along the through holes of the heat storage body 35 to the adjacent conical shell 50. The following is described by taking the use of the left chamber of the processing box 31 as an example: After the heat storage body 35 in the left chamber has been used for a certain period of time, in order to avoid clogging of the through holes on the heat storage body 35 in the left chamber by solid impurities after combustion and solid impurities contained in the exhaust gas, the remote control terminal starts the first electric push rod 39, and the telescopic end of the first electric push rod 39 drives the adjacent fixed rod 38 to move synchronously to the left through the adjacent connecting seat, and the fixed rod 38 drives the adjacent blocking plate 37 to move synchronously to the left, and the through holes on the blocking plate 37 are misaligned with the adjacent through holes on the adjacent air guide shell 36, that is, the through holes on the adjacent air guide shell 36 are blocked by the blocking plate 37, and at the same time the remote control terminal shuts down the first electric push rod 39 on the left.

[0028] After the through holes on the adjacent air guide shell 36 on the left are blocked, the remote control terminal starts four air pumps and simultaneously opens the solenoid valves on the four guide tubes 41 on the left, and the four air pumps respectively deliver clean air to the four cavities on the left air guide shell 36 through the adjacent cleaning tubes 40 and the adjacent guide tubes 41 on the left, and the air delivered to the four cavities in the left air guide shell 36 synchronously flows downward along the through holes of the adjacent parts of the adjacent heat storage body 35, and the residual solid impurities in the four parts of the through holes of the left heat storage body 35 are cleaned to avoid the accumulation of solid impurities in the four parts of the through holes of the left heat storage body 35, and at the same time, prevent the solid impurities from falling on the left heat storage body 35 again, or even adhering to the through holes of the left heat storage body 35, causing blockage of the four parts of the through holes of the left heat storage body 35, thereby affecting the normal use of the heat storage body 35.

[0029] In the above-mentioned process of cleaning the solid impurities in the four through holes of the left heat storage body 35, if the solid impurities in a part of the through holes of the heat storage body 35 have blocked the part of the through holes, in the process of transporting gas to the part of the through holes of the heat storage body 35, the resistance encountered by the gas when flowing into the part of the through holes increases, thereby increasing the value detected by the pressure detector in the guide tube 41 connected to the part of the through holes. Subsequently, the remote control terminal increases the output power of the air pump connected to the guide tube 41 according to the change in the value of the pressure detector, thereby increasing the flow rate of the gas when flowing into the part of the through holes, thereby increasing the impact force on the solid impurities in the part of the through holes. If the value detected by the pressure detector in the guide tube 41 gradually decreases at this time, it proves that the solid impurities in the part of the through holes are gradually cleaned up. After the value detected by the pressure detector in the guide tube 41 returns to the initial value, the remote control terminal shuts down the four air pumps and the solenoid valves on the four guide tubes 41 on the left.

[0030] If the value detected by the pressure detector in the guide tube 41 continues to increase, it proves that the blockage of the through hole at that location is relatively serious. At this time, simply relying on the blowing of the above-mentioned gas cannot clean out the impurities in the through hole. Then the remote control terminal shuts down the four air pumps and simultaneously shuts down the solenoid valves on the four guide tubes 41 on the left side.

[0031] After the solenoid valves on the four guide pipes 41 on the left are shut down, the staff replaces the heat storage body 35 on the left, and cleans and repairs the replaced heat storage body 35 to ensure that the heat storage body 35 can be used continuously.

[0032] During the above-mentioned process of replacing the left heat storage body 35, or when the staff fails to replace the left heat storage body 35 in time, the remote control terminal opens the solenoid valve on the left shunt pipe 42, so that the exhaust gas flows to the treatment box 31 through the intake pipe 32 and the left shunt pipe 42, and simultaneously opens the solenoid valve between the two chambers B and C and the exhaust pipe 33, so that the exhaust gas after combustion treatment flows into the exhaust pipe through the two chambers B and C and the exhaust pipe 33, and adjusts the work flow of the above-mentioned treatment box 31 to ensure that the device can be used continuously during the process of replacing the heat storage body 35. At the same time, after the replacement of the left heat storage body 35 is completed, the remote control terminal The control terminal starts the first electric push rod 39 on the left, and the telescopic end of the first electric push rod 39 on the left drives the adjacent blocking plate 37 to reset to the right synchronously through the adjacent connecting seat and the adjacent fixing rod 38, until the left blocking plate 37 is reset to the right to the initial position, and then the remote control terminal shuts down the first electric push rod 39 on the left. At this time, the through hole on the blocking plate 37 is connected to the adjacent through hole on the adjacent air guide shell 36, and then the remote control terminal simultaneously shuts down the first electric push rod 39 on the left and the solenoid valve on the left shunt pipe 42, and synchronously adjusts the other parts mentioned above (the specific adjustment process can be referred to above), and restores the workflow.

[0033] Before the remote control terminal starts the four air pumps, the remote control terminal first starts the second electric push rod 53 on the left, and the telescopic end of the second electric push rod 53 on the left drives the adjacent blocking block 51 to move upward synchronously through the transmission of the adjacent connecting piece and the adjacent connecting rod, so as to open the lower port of the left conical shell 50. When the telescopic end of the second electric push rod 53 on the left moves upward to the limit position, the remote control terminal stops the second electric push rod 53 on the left, so that the impurities in the left conical shell 50 fall downward along the lower port thereof into the receiving block 52 on the left. In the above process of cleaning the impurities in the through hole of the left heat storage body 35, The cleaned impurities fall downward into the left conical shell 50, and fall downward along its lower port into the receiving block 52 on the left, until the impurities in the through hole of the left heat storage body 35 are cleaned, the remote control terminal reversely starts the left second electric push rod 53, and the telescopic end of the left second electric push rod 53 drives the left blocking block 51 to return to the initial position downward, and then the remote control terminal shuts down the left second electric push rod 53, so that the left blocking block 51 re-blocks the lower port of the left conical shell 50, and the staff cleans the impurities in the receiving block 52, and the solid impurities in the left conical shell 50 are completely dropped out.

[0034] After the telescopic end of the left second electric push rod 53 is reset to the initial position as mentioned above, the left first electric push rod 39 is started by the remote control terminal, and the telescopic end of the left first electric push rod 39 drives the adjacent blocking plate 37 to reset to the right synchronously through the adjacent connecting seat and the adjacent fixing rod 38, until the left blocking plate 37 is reset to the initial position to the right, and the through hole on the blocking plate 37 is connected with the adjacent through hole on the adjacent air guide shell 36, and then the remote control terminal shuts down the left first electric push rod 39.

[0035] The replacement process of the middle and right heat storage bodies 35 and the movement process of the telescopic ends of the middle and right second electric push rods 53 can refer to the above. When the above-mentioned device is used to treat the exhaust gas for a certain period of time, the remote control terminal is used to shut down the exhaust fan and reset all the above-mentioned parts to their initial positions. After confirming that there is no residual exhaust gas in each pipeline and the treatment box 31, the staff will inspect and repair the device.

[0036] Example 2: Based on Example 1, considering that the volume of waste gas generated by the waste gas source per unit time during the use of the existing regenerative thermal incinerator is not stable, if the output of waste gas suddenly increases during normal use, it is easy to cause part of the waste gas to be discharged into the atmosphere before it is fully burned, so that the treatment quality of the waste gas by the regenerative thermal incinerator is reduced. When the output of waste gas suddenly decreases, the temperature inside the RTO will fluctuate, increasing the demand for external heat sources and further increasing the consumption of fuel. The present invention proposes the following measures: like Figure 1 , Figure 2 and Figure 8-Figure 11As shown, it also includes a fixing frame 1, which is arranged on the left side of the induced draft fan, and a preheating mechanism is arranged on the fixing frame 1. The fixing frame 1 is provided with a storage tank 2 through the preheating mechanism, and the storage tank 2 is used to temporarily store excess exhaust gas. The front side of the fixing frame 1 is fixedly connected to an air supply pipe 3, and the air supply pipe 3 is connected to the exhaust gas generating module. The rear side of the air supply pipe 3 is fixedly connected and connected to a U-shaped pipe 4. Both ends of the U-shaped pipe 4 are provided with a one-way valve, wherein the one-way valve in the left end of the U-shaped pipe 4 can allow external substances to enter. The one-way valve in the right port of the U-shaped tube 4 can only transport the substances therein to the outside. The U-shaped tube 4 is fixedly connected and communicated with the storage tank 2. The exhaust gas is transported to the storage tank 2 by the gas pipe 3 through the port on the left side of the U-shaped tube 4. The interior of the gas pipe 3 is slidably connected with a mobile pipe 5. A filter screen 6 is installed inside the mobile pipe 5 to detect the flow rate of the exhaust gas in the gas pipe 3. The mobile pipe 5 is provided with two gas delivery ports 7 symmetrically distributed on the left and right, wherein the left gas delivery port 7 is communicated and coordinated with the left port of the U-shaped tube 4, and the right gas delivery port 7 is communicated and coordinated with the right port of the U-shaped tube 4. In the initial position, the left gas delivery port 7 is not in a state of communication with the left port of the U-shaped tube 4, and the right gas delivery port 7 is in a state of communication with the right port of the U-shaped tube 4, and the mobile pipe 5 is in a port blocking cooperation with the U-shaped tube 4, and the distance between the two gas delivery ports 7 is greater than the distance between the two ports on the U-shaped tube 4. The two ports of the U-shaped tube 4 are blocked by the mobile pipe 5, so that only one of the two ports on the U-shaped tube 4 is in contact with the corresponding one at the same time. The movable pipe 5 is connected to the adjacent gas delivery port 7, and a first elastic member 8 is fixedly connected between the movable pipe 5 and the gas delivery pipe 3. The first elastic member 8 is a spring, which is used to maintain the initial position of the movable pipe 5 and drive the movable pipe 5 to return to the initial position after movement. The right end of the gas delivery pipe 3 is fixedly connected and connected with a guide pipe 9. The guide pipe 9 is a three-way pipe, wherein the right end of the gas delivery pipe 3 is connected with the upper end of the guide pipe 9, and the right side of the guide pipe 9 is fixedly connected and connected with the induced draft fan, which draws the exhaust gas to the right through the transmission between the guide pipe 9 and the gas delivery pipe 3.

[0037] like Figure 8-Figure 11As shown, the preheating mechanism includes a heating shell 10, the heating shell 10 is fixedly connected to the fixing frame 1, the storage tank 2 is fixedly connected to the inside of the heating shell 10, the U-shaped tube 4 passes through the heating shell 10, the diameter of the storage tank 2 is smaller than the diameter of the heating shell 10, the inside of the heating shell 10 is slidably connected with a shielding ring 11, the shielding ring 11 is slidably connected to the storage tank 2, the storage tank 2, the heating shell 10 and the lower side of the shielding ring 11 cooperate with each other to form a heating chamber, and the volume of the heating chamber is changed by changing the position of the shielding ring 11, and the upper side of the storage tank 2 is fixedly connected to the first hydraulic telescopic rod 12 through a connecting piece. In the initial position, the telescopic end of the first hydraulic telescopic rod 12 is in an extended state, and the heating shell 1 0 is fixedly connected to the lower side of the second hydraulic telescopic rod 13, the telescopic end of the second hydraulic telescopic rod 13 is fixedly connected to the shielding ring 11, the telescopic end of the second hydraulic telescopic rod 13 drives the shielding ring 11 to move synchronously, thereby changing the volume of the heating chamber, and the fixed part of the second hydraulic telescopic rod 13 is connected with the fixed part of the first hydraulic telescopic rod 12 through a connecting pipe, the fixed part of the first hydraulic telescopic rod 12, the fixed part of the second hydraulic telescopic rod 13 and the connecting pipe between the fixed parts of the two are filled with hydraulic oil, and the telescopic end of the first hydraulic telescopic rod 12 transfers the hydraulic oil in its fixed part to the fixed part of the second hydraulic telescopic rod 13 through the connecting pipe during the upward movement, and the inner part of the storage tank 2 is filled with hydraulic oil. The movable plate 14 is slidably connected to the storage tank 2, and the exhaust gas in the storage tank 2 squeezes the movable plate 14 to move the movable plate 14 upward. The movable plate 14 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 12, and the movable plate 14 drives the telescopic end of the first hydraulic telescopic rod 12 to move upward synchronously. A second elastic member 15 is fixedly connected between the connecting member on the storage tank 2 and the movable plate 14. The second elastic member 15 is a spring, which is used to maintain the initial position of the movable plate 14 and drive the movable plate 14 to reset to the initial position after moving. The heating shell 10 is connected to the exhaust pipe 33 through the connecting pipe, and the treated hot air in the exhaust pipe 33 is guided into the heating shell 10, so as to exhaust the waste gas stored in the storage tank 2. Preheating is performed, and the distance between the inner wall of the heating shell 10 and the outer wall of the storage tank 2 is the same as the distance between the bottom of the heating shell 10 and the bottom of the storage tank 2, which is used to increase the uniformity of the hot gas heating the exhaust gas in the storage tank 2, and the shielding ring 11 is fixedly connected with a connecting pipe connected to the exhaust pipe, which is used to transport the exhaust gas after heat exchange in the heating chamber to the exhaust pipe. An air supply pipe 20 is fixedly connected to the front lower side of the fixed frame 1, and the air supply pipe 20 is fixedly connected and connected to the guide pipe 9. The air supply pipe 20 is externally connected to an air supply pump, which is used to increase the oxygen content of the exhaust gas introduced into the treatment box 31 by the air pump through the air supply pipe 20 and the guide pipe 9 to introduce a small amount of air into the intake pipe 32 when the exhaust gas output is small.

[0038] Before the above-mentioned remote control terminal starts the induced draft fan, the staff connects the right end of the guide pipe 9 with the input port of the induced draft fan, and the induced draft fan transports the pretreated exhaust gas to the intake pipe 32 through the air pipe 3. Then the remote control terminal starts the air pump, and the air pump transports a small amount of air per unit time to the guide pipe 9 through the air supply pipe 20, thereby increasing the oxygen content of the exhaust gas entering the treatment box 31, thereby increasing the combustion temperature of the exhaust gas, and avoiding the decrease in the exhaust gas combustion temperature when the exhaust gas output decreases, resulting in the heat storage body 35 being unable to be fully heated, and the exhaust gas passing through the heat storage body 35 being unable to be fully preheated, resulting in the exhaust gas requiring an additional heat source to be fully burned, thereby increasing fuel consumption.

[0039] In the process of exhaust gas flowing to the right along the gas pipe 3, if the output of exhaust gas gradually increases, the exhaust gas squeezes the filter screen 6, so that the filter screen 6 is squeezed by the exhaust gas and drives the movable tube 5 to move to the right synchronously, and at the same time, the first elastic member 8 is compressed and stored. In the process of the movable tube 5 moving to the right, the connection area between the right gas port 7 and the right end of the U-shaped tube 4 gradually decreases until the right gas port 7 and the right end of the U-shaped tube 4 are completely staggered, that is, the gas port 7 completely blocks the right end of the U-shaped tube 4. At this time, the first elastic member 8 is compressed to half of its maximum deformation, and at the same time, the right side of the left gas port 7 moves to a position in contact with the left side of the left end of the U-shaped tube 4 (but the two are not connected). At this time, the output of exhaust gas per unit time is the same as the maximum processing capacity of the treatment box 31 per unit time. Then the remote control terminal shuts down the air pump and stops supplying air to the treatment box 31 to avoid excessive pressure of the gas in the treatment box 31.

[0040] When the movable tube 5 moves to the right to compress the first elastic member 8 to half of its maximum deformation, if the output of the exhaust gas continues to increase, the filter screen 6 drives the movable tube 5 to continue to move to the right, gradually connecting the left gas outlet 7 with the left end of the U-shaped tube 4, so that the exhaust gas flows to the left end of the U-shaped tube 4 during the process of flowing to the right along the gas pipe 3, and then flows along the left end of the U-shaped tube 4 to the storage tank 2, storing part of the exhaust gas, and avoiding the exhaust gas from being discharged when the exhaust gas output is too much. It continues to flow into the treatment box 31, causing part of the exhaust gas to be discharged into the atmosphere before being fully burned, reducing the quality of exhaust gas treatment by the device, and at the same time avoiding the continuous increase in pressure of the exhaust gas on the pipeline when the exhaust gas output increases, causing the pipeline to be damaged due to excessive pressure, causing the exhaust gas to leak into the atmosphere. At the same time, the connecting pipe on the lower side of the heating shell 10 guides the partially treated exhaust gas in the exhaust pipe 33 into the heating shell 10 to preheat the exhaust gas stored in the storage tank 2.

[0041] During the process of the exhaust gas flowing into the storage tank 2, the exhaust gas flowing into the storage tank 2 squeezes the movable plate 14, causing the movable plate 14 to move upward along the inner wall of the storage tank 2, compressing the second elastic member 15 to store force, and at the same time, the movable plate 14 drives the telescopic end of the first hydraulic telescopic rod 12 to move upward synchronously, so that the hydraulic oil in the fixed part of the first hydraulic telescopic rod 12 is transported to the fixed part of the second hydraulic telescopic rod 13 through the connecting pipe, thereby causing the telescopic end of the second hydraulic telescopic rod 13 to move upward, and the telescopic end of the second hydraulic telescopic rod 13 drives the shielding ring 11 to move upward synchronously, increasing the volume of the heating cavity formed by the lower side of the shielding ring 11, the outer side of the storage tank 2 and the inner wall of the heating shell 10, thereby changing the heating area of ​​the storage tank 2, so that the hot gas stored in the storage tank 2 can be fully preheated.

[0042] In the above-mentioned process of storing the exhaust gas by the storage tank 2, if the output of the exhaust gas suddenly decreases, the speed of the exhaust gas flowing into the storage tank 2 is synchronously reduced, and at the same time, the impact force of the exhaust gas on the filter 6 is reduced, so that the extrusion pressure of the mobile tube 5 on the first elastic member 8 is synchronously reduced. The mobile tube 5 and other parts connected thereto gradually move to the left under the action of the first elastic member 8, staggering the left gas delivery port 7 and the left port of the U-shaped tube 4, and the left port of the U-shaped tube 4 is blocked by the mobile tube 5 until the left gas delivery port 7 moves to the left to the right side and is flush with the left side of the left port of the U-shaped tube 4. The output volume of the exhaust gas per unit time is the same as the maximum volume of the exhaust gas treated by the treatment box 31 per unit time.

[0043] If the volume of exhaust gas produced per unit time continues to decrease, the movable tube 5 and other parts connected thereto will continue to move forward under the action of the first elastic member 8. During this process, the right gas outlet 7 is gradually connected to the right port of the U-shaped tube 4, and then the second elastic member 15 drives the movable plate 14 to move downward synchronously, squeezing the exhaust gas stored in the storage tank 2 into the U-shaped tube 4, and the exhaust gas stored in the storage tank 2 is used to supplement the exhaust gas flowing in the gas pipe 3, so as to avoid a decrease in the volume of exhaust gas treated by the treatment box 31 per unit time when the exhaust gas output continues to decrease, thereby reducing the heat generated during the combustion of the exhaust gas and failing to heat the heat storage body 35 to a specified stability, resulting in an increase in the demand for external heat sources and an increase in fuel consumption.

[0044] After the waste gas stored in the storage tank 2 is completely discharged, the remote control terminal starts the air supply pump again, and the air supply pump again delivers air to the air inlet pipe 32 through the air supply pipe 20 to increase the oxygen content of the waste gas entering the treatment box 31. In the process of using this device to carry out combustion treatment of the waste gas process, the staff shall regularly inspect and maintain the device. During the inspection and maintenance, the remote control terminal shall shut down the above-mentioned device, and the staff shall inspect and maintain the device only when it is ensured that there is no residual waste gas in the various pipelines and the treatment box 31 of the device.

Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
