Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment devices, and particularly to an energy-saving and environment-friendly RTO device for the production of dipped cord fabric. Background Art

[0002] In the process of producing 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 solvents in the adhesive will volatilize to form waste gas during this process. At the same time, after dipping, the cord fabric needs to be dried to remove excess moisture and solvents inside. During the drying process, volatile organic compounds and other harmful substances will be discharged together with the hot air.

[0003] For waste gas containing volatile organic compounds, an RTO device is usually used for treatment. The RTO device converts harmful substances in the waste gas into carbon dioxide and water through high-temperature oxidation, and at the same time uses a heat storage body (usually honeycomb ceramics) to store and recover heat. Compared with traditional catalytic combustion and direct combustion oxidation furnaces, RTO significantly reduces energy consumption and greenhouse gas emissions through efficient heat recovery.

[0004] In the current regenerative thermal oxidizer during use, the waste gas first undergoes preheating treatment through the heat storage body. During this process, some of the solid impurities contained in the waste gas will adhere to the through-holes of the heat storage body. At the same time, the solid impurities generated during the combustion of the waste gas will also fall into the through-holes of the heat storage body, thereby reducing the flow area of the through-holes of the heat storage body. The existing regenerative thermal oxidizer will perform a backwashing operation on the heat storage body during use to remove impurities in the heat storage body. However, the main purpose of this backwashing operation is to remove the residual waste gas in the heat storage body. Although some impurities in the heat storage body can be removed when cleaning the waste gas, the impurities blown out by the gas will still fall back onto the heat storage body again and enter or even adhere to the through-holes of the heat storage body again, affecting the flow area of the heat storage body and even blocking the through-holes of the heat storage body. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0032] Embodiment 1: Considering that it is not convenient to clean the heat storage body in the existing heat storage incinerator during use, and the through holes on the heat storage body are easily blocked after long-term use, the present invention proposes an energy-saving and environmentally friendly RTO device for the production of dipped cord fabrics:

[0033] like Figures 1-6As shown in the figure, it includes a chassis 30. On the upper side of the chassis 30, a treatment box 31 is installed. On the upper side of the treatment box 31, a combustion assisting module is installed. The combustion assisting module is network-connected to a remote control terminal. The combustion assisting module is an existing device and is used to increase the temperature in the treatment box 31 to ensure that the waste gas can be fully burned. On the left side of the chassis 30, an induced draft fan network-connected to the remote control terminal is provided. The induced draft fan is used to extract the waste gas generated by the waste gas source. On the right side of the chassis 30, an exhaust pipe is provided for discharging the treated waste gas into the atmosphere. The upper part of the treatment box 31 is a combustion chamber. The treatment box 31 is provided with three interconnected chambers. On the front side of the treatment box 31, an intake pipe 32 is fixedly connected (for introducing the waste gas into the lower side of the interior of the treatment box 31). On the rear side of the treatment box 31, an exhaust pipe 33 is fixedly connected (for guiding the treated waste gas). On the front side of the treatment box 31, a backflush pipe 34 is fixedly connected. The intake pipe 32, the exhaust pipe 33, and the backflush pipe 34 are all connected to the three chambers of the treatment box 31 through connecting pipes. And the connecting pipes on the intake pipe 32, the exhaust pipe 33, and the backflush pipe 34 are all installed with solenoid valves network-connected to the remote control terminal, which are used to change the connection relationship between the intake pipe 32, the exhaust pipe 33, and the backflush pipe 34 and the three chambers of the treatment box 31. Among them, the intake pipe 32 is connected to the induced draft fan, and the induced draft fan transports the waste gas to the intake pipe 32. The exhaust pipe 33 and the backflush pipe 34 are connected, which is used to divert the treated waste gas so that part of the treated waste gas re-enters the treatment box 31. And the exhaust pipe 33 is connected to the exhaust pipe for guiding the treated waste gas into the exhaust pipe. A heat storage body 35 is installed in the chamber of the treatment box 31. The heat storage body 35 is provided with through holes. The heat storage body 35 is used to preheat the waste gas introduced into the treatment box 31. In the three chambers of the treatment box 31, a gas guide shell 36 is fixedly connected. The gas guide shell 36 is provided with through holes communicating with the adjacent heat storage body 35. The lower side of the gas guide shell 36 is provided with four cavities distributed in a matrix. At the same time, the through holes on the adjacent heat storage body 35 are also divided into four parts by the four cavities on the gas guide shell 36. A plugging plate 37 is slidably connected to the upper side of the gas guide shell 36. The plugging plate 37 is provided with through holes distributed in a matrix. The through holes on the plugging plate 37 are in communication and cooperation with the adjacent through holes on the adjacent gas guide shell 36. The through holes on the adjacent gas guide shell 36 are blocked by the plugging plate 37. In the initial position, the through holes on the plugging plate 37 are in communication with the adjacent through holes on the adjacent gas guide shell 36. On the upper sides of the heat storage body 35 and the plugging plate 37, quadrangular pyramids distributed in a matrix are provided. The adjacent quadrangular pyramids are in mutual contact. And on the upper parts of the heat storage body 35 and the plugging plate 37, inclined surfaces distributed in a ring shape are provided. The bottom of the quadrangular pyramid is lower than the upper side of the adjacent inclined surface, which is used to divert the impurities on the upper sides of the heat storage body 35 and the plugging plate 37, so that the solid impurities in the treatment box 31 move into the through holes of the heat storage body 35 for subsequent cleaning. A cleaning mechanism is provided on the treatment box 31, and the cleaning mechanism is used to clean the through holes of the linear array of heat storage bodies 35.

[0034] As Figures 3-6As shown, a fixed rod 38 is fixedly connected to the front part of the upper side of the plugging plate 37. The three fixed rods 38 all penetrate through the treatment box 31 and are slidably connected thereto. Three first electric push rods 39 arranged in a linear array are installed in the middle of the front side of the treatment box 31. The first electric push rods 39 are connected to the remote control terminal through the network. The telescopic ends of the first electric push rods 39 are fixedly connected to the adjacent fixed rods 38 through connecting seats. The adjacent plugging plate 37 is driven to move by the transmission of the telescopic ends of the first electric push rods 39 through the adjacent connecting seats and adjacent fixed rods 38, so as to adjust the relative positions of the plugging plate 37 and the adjacent air guide shell 36, and then the through holes on the adjacent air guide shell 36 are blocked by the plugging plate 37.

[0035] As Figures 1-5 As shown, the cleaning mechanism includes two groups of cleaning pipes 40 symmetrically distributed in the front and rear. The two groups of cleaning pipes 40 are both fixedly connected to the outside of the treatment box 31. Each group of cleaning pipes 40 is provided with two symmetrically distributed around the center. Four air pumps arranged in a matrix are installed on the outside of the treatment box 31. The four cleaning pipes 40 are respectively communicated with the output ends of the adjacent air pumps. Clean air is introduced into the four cleaning pipes 40 by the four air pumps respectively. Three guide pipes 41 arranged in a linear array are fixedly connected and communicated on the opposite sides of each group of cleaning pipes 40. The guide pipes 41 on the adjacent two cleaning pipes 40 are staggered. The guide pipes 41 penetrate through the treatment box 31 and are communicated with the adjacent cavities on the adjacent air guide shell 36. Clean air is introduced into the adjacent cavities on the air guide shell 36 by the transmission of the air pumps through the adjacent cleaning pipes 40 and the adjacent three guide pipes 41, and the impurities in the through holes of the adjacent regenerators 35 are blown downward. And the guide pipes 41 are provided with solenoid valves (an existing device, not shown in the figure) connected to the remote control terminal through the network. A pressure detector connected to the remote control terminal through the network is installed inside the guide pipes 41, which is used to detect the resistance when the air flows into the through holes of the regenerator 35, and then judge the fluidity of the through holes of the regenerator 35. A shunt pipe 42 arranged in a linear array is fixedly connected and communicated to the upper side of the air inlet pipe 32. The three chambers of the treatment box 31 are respectively communicated with the adjacent shunt pipes 42. The shunt pipes 42 are provided with solenoid valves connected to the remote control terminal through the network. The positions where the three chambers of the treatment box 31 are communicated with the adjacent shunt pipes 42 are respectively located above the adjacent plugging plates 37, which are used to shunt the waste gas in the air inlet pipe 32. After the regenerator 35 is plugged, the waste gas directly flows into the treatment box 31 through the shunt pipe 42.

[0036] As Figures 1-4 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 is fixedly connected with the connecting rod of the adjacent guiding block 52. 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.

[0037] 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.

[0038] 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:

[0039] 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.

[0040] After blocking the through holes on the left adjacent air guide housing 36, the remote control terminal turns on four air pumps and simultaneously turns on the solenoid valves on the four left-side guide pipes 41. The four air pumps respectively deliver clean air into the four cavities on the left air guide housing 36 through the adjacent cleaning pipes 40 and the adjacent left-side guide pipes 41. The air delivered into the four cavities of the left air guide housing 36 synchronously flows downward along the through holes in the adjacent parts of the adjacent regenerator 35 to clean the residual solid impurities in the four parts of the through holes of the left regenerator 35, avoiding the accumulation of solid impurities in the four parts of the through holes of the left regenerator 35, and at the same time preventing the solid impurities from falling onto the left regenerator 35 again or even adhering to the through holes of the left regenerator 35, causing blockage of the four parts of the through holes of the left regenerator 35 and thus affecting the normal use of the regenerator 35.

[0041] During the process of cleaning the solid impurities in the four parts of the through holes of the left regenerator 35 as described above, if the solid impurities in a certain part of the through holes of the regenerator 35 have blocked that part of the through holes, during the process of delivering gas into that part of the through holes of the regenerator 35 at this time, the resistance of the gas flowing into that part of the through holes increases, and then the value detected by the pressure detector in the guide pipe 41 connected to that part of the through holes increases. Subsequently, the remote control terminal increases the output power of the air pump connected to that guide pipe 41 according to the change in the value of the pressure detector, thereby increasing the flow rate of the gas flowing into that part of the through holes, increasing the impact force on the solid impurities in that part of the through holes. If the value detected by the pressure detector in that guide pipe 41 gradually decreases at this time, it proves that the solid impurities in that part of the through holes are gradually cleared. After the value detected by the pressure detector in that guide pipe 41 returns to the initial value, the remote control terminal shuts down the four air pumps and the solenoid valves on the four left-side guide pipes 41.

[0042] If the value detected by the pressure detector in that guide pipe 41 continues to increase, it proves that the blockage of the through hole at that place is relatively serious. At this time, simply relying on the blowing of the above gas cannot clean the impurities in that part of the through hole. Subsequently, the remote control terminal shuts down the four air pumps and simultaneously shuts down the solenoid valves on the four left-side guide pipes 41.

[0043] After shutting down the solenoid valves on the four left-side guide pipes 41 as described above, the staff replaces the left regenerator 35 and cleans and repairs the replaced regenerator 35 to ensure the sustainable use of the regenerator 35.

[0044] 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.

[0045] 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.

[0046] After the telescopic end of the second electric push rod 53 on the left is reset to the initial position as described above, the remote control terminal starts the first electric push rod 39 on the left. The telescopic end of the first electric push rod 39 on the left drives the adjacent sealing plate 37 to reset synchronously to the right through the transmission of the adjacent connecting seat and the adjacent fixing rod 38. Until the left sealing plate 37 is reset to the initial position to the right, the through hole on the sealing plate 37 communicates with the adjacent through hole on the adjacent air guide shell 36, and then the remote control terminal shuts down the first electric push rod 39 on the left.

[0047] The replacement process of the middle and right heat storage bodies 35 and the movement process of the telescopic ends of the second electric push rods 53 in the middle and on the right can be referred to the above. When the waste gas treatment using the above device reaches a certain time, the remote control terminal shuts down the induced draft fan, and after resetting the above parts to the initial position, when it is confirmed that there is no residual waste gas in each pipeline and the treatment tank 31, the staff repairs the device.

[0048] Embodiment 2: On the basis of Embodiment 1, considering that in the process of using the existing regenerative incinerator, the volume of waste gas generated by the waste gas source per unit time is not stable. If the output of waste gas suddenly increases during normal use, it is easy to cause some waste gas to be discharged into the atmosphere before being fully burned, reducing the treatment quality of the regenerative incinerator for waste gas. When the output of waste gas suddenly decreases, it will cause the temperature inside the RTO to fluctuate, increasing the demand for external heat sources and thus increasing the consumption of fuel. The present invention proposes the following measures:

[0049] Such as Figure 1 、 Figure 2 and Figures 8-11As shown in the figure, it further includes a fixing frame 1. The fixing frame 1 is arranged on the left side of the induced draft fan. A preheating mechanism is arranged on the fixing frame 1. A storage tank 2 is arranged on the fixing frame 1 through the preheating mechanism. The storage tank 2 is used for temporarily storing excessive waste gas. A gas transmission pipe 3 is fixedly connected to the front side of the fixing frame 1. The gas transmission pipe 3 is communicated with the waste gas generation module. The rear side of the gas transmission pipe 3 is fixedly connected and communicated with a U-shaped pipe 4. One-way valves are arranged at both ports of the U-shaped pipe 4. The one-way valve in the left port of the U-shaped pipe 4 can allow external substances to enter it, and the one-way valve in the right port of the U-shaped pipe 4 can only transport the substances inside it to the outside. The U-shaped pipe 4 is fixedly connected and communicated with the storage tank 2. The waste gas is transported into the storage tank 2 through the left port of the U-shaped pipe 4 by the gas transmission pipe 3. A moving pipe 5 is slidably connected inside the gas transmission pipe 3. A filter screen 6 is installed inside the moving pipe 5 for detecting the flow rate of the waste gas in the gas transmission pipe 3. The moving pipe 5 is provided with two symmetrically distributed gas outlets 7 on the left and right. The left gas outlet 7 is in communication and cooperation with the left port of the U-shaped pipe 4, and the right gas outlet 7 is in communication and cooperation with the right port of the U-shaped pipe 4. In the initial position, the left gas outlet 7 is not in a state of being communicated with the left port of the U-shaped pipe 4, and the right gas outlet 7 is in a state of being communicated with the right port of the U-shaped pipe 4. And the moving pipe 5 is in sealing cooperation with the ports of the U-shaped pipe 4. The distance between the two gas outlets 7 is greater than the distance between the two ports on the U-shaped pipe 4. The two ports of the U-shaped pipe 4 are blocked by the moving pipe 5, so that only one of the two ports on the U-shaped pipe 4 is communicated with the adjacent gas outlet 7 at the same time. A first elastic member 8 is fixedly connected between the moving pipe 5 and the gas transmission pipe 3. The first elastic member 8 is a spring, which is used to maintain the initial position of the moving pipe 5 and drive the moved moving pipe 5 to reset to the initial position. The right end of the gas transmission pipe 3 is fixedly connected and communicated with a guiding pipe 9. The guiding pipe 9 is a three-way pipe. The right end of the gas transmission pipe 3 is communicated with the upper port of the guiding pipe 9. The right side of the guiding pipe 9 is fixedly connected and communicated with the induced draft fan. The induced draft fan draws the waste gas to the right through the guiding pipe 9 and the gas transmission pipe 3.

[0050] As Figures 8-11As shown in the figure, 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 that of the heating shell 10, a shielding ring 11 is slidably connected to the inside of the heating shell 10, the shielding ring 11 is slidably connected to the storage tank 2, and the lower sides of the storage tank 2, the heating shell 10 and the shielding ring 11 cooperate with each other to form a heating chamber. The volume of the heating chamber is changed by changing the position of the shielding ring 11. A first hydraulic telescopic rod 12 is fixedly connected to the upper side inside the storage tank 2 through a connecting member. In the initial position, the telescopic end of the first hydraulic telescopic rod 12 is in the extended state. A second hydraulic telescopic rod 13 is fixedly connected to the lower side of the heating shell 10, and 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. Moreover, the fixed part of the second hydraulic telescopic rod 13 and the fixed part of the first hydraulic telescopic rod 12 are communicated through a connecting pipe. The fixed parts of the first hydraulic telescopic rod 12, the fixed part of the second hydraulic telescopic rod 13 and the connecting pipe between the two fixed parts are all filled with hydraulic oil. When the telescopic end of the first hydraulic telescopic rod 12 moves upward, the hydraulic oil in its fixed part is conveyed to the fixed part of the second hydraulic telescopic rod 13 through the connecting pipe. A moving plate 14 is slidably connected to the inside of the storage tank 2. The moving plate 14 is pushed upward by the waste gas in the storage tank 2, so that the moving plate 14 moves upward. The moving plate 14 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 12, and the moving 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 moving plate 14. The second elastic member 15 is a spring, which is used to maintain the initial position of the moving plate 14 and drive the moved moving plate 14 to reset to the initial position. The heating shell 10 is communicated with the exhaust pipe 33 through a connecting pipe, guiding the heated gas in the exhaust pipe 33 into the heating shell 10 to preheat the waste gas stored in the storage tank 2. The distance between the inner side wall of the heating shell 10 and the outer side 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 heated gas heating the waste gas in the storage tank 2. Moreover, the shielding ring 11 is fixedly connected with a connecting pipe communicated with the discharge pipe, which is used to convey the waste gas after heat exchange in the heating chamber into the discharge pipe. A supplementary air pipe 20 is fixedly connected to the front lower side of the fixing frame 1. The supplementary air pipe 20 is fixedly connected and communicated with the guiding pipe 9. The supplementary air pipe 20 is externally connected with an air supplementing pump, which is used to introduce a small amount of air into the intake pipe 32 through the supplementary air pipe 20 and the guiding pipe 9 by the air pump when the output of the waste gas is small, so as to increase the oxygen content of the waste gas introduced into the treatment box 31.

[0051] Before the induced draft fan is started by the remote control terminal, the staff will connect the right end of the guiding pipe 9 to the input port of the induced draft fan, and the induced draft fan will transport the pretreated waste gas through the gas transmission pipe 3 into the air inlet pipe 32. Subsequently, the remote control terminal starts the gas transmission pump, and the gas transmission pump transports a small amount of air into the guiding pipe 9 per unit time through the supplementary gas pipe 20, increasing the oxygen content of the waste gas introduced into the treatment tank 31, thereby increasing the combustion temperature of the waste gas, and avoiding the decrease in the combustion temperature of the waste gas when the output of the waste gas decreases, resulting in the regenerator 35 not being fully heated, and the waste gas passing through the regenerator 35 not being fully preheated, resulting in the waste gas requiring additional heat sources to fully burn, increasing the fuel consumption.

[0052] During the process of the waste gas flowing rightward along the gas transmission pipe 3, if the output of the waste gas gradually increases, the waste gas squeezes the filter net 6, causing the filter net 6 to be driven by the squeezing of the waste gas to move rightward synchronously with the moving pipe 5, and at the same time compressing the first elastic member 8 to store energy. During the process of the moving pipe 5 moving rightward, the communication area between the right gas transmission port 7 and the right port of the U-shaped pipe 4 gradually decreases. When the right gas transmission port 7 and the right port of the U-shaped pipe 4 are completely staggered, that is, the gas transmission port 7 completely blocks the right port of the U-shaped pipe 4. At this time, the first elastic member 8 is compressed to half of its maximum deformation amount, and at the same time, the right side of the left gas transmission port 7 moves to a position in contact with the left side of the left port of the U-shaped pipe 4 (but the two are not connected). At this time, the output of the waste gas per unit time is the same as the maximum processing amount of the treatment tank 31 per unit time. Subsequently, the remote control terminal shuts down the air pump to stop transporting air into the treatment tank 31 to avoid excessive pressure in the gas in the treatment tank 31.

[0053] When the moving pipe 5 moves rightward to compress the first elastic member 8 to half of its maximum deformation amount as described above, if the output of the waste gas continues to increase, the filter net 6 drives the moving pipe 5 to continue moving rightward, gradually connecting the left gas transmission port 7 and the left port of the U-shaped pipe 4, so that during the process of the waste gas flowing rightward along the gas transmission pipe 3, a part of the waste gas flowing into the left port of the U-shaped pipe 4 is diverted, and then flows into the storage tank 2 along the left port of the U-shaped pipe 4 to store part of the waste gas, avoiding that when the output of the waste gas is excessive, the waste gas continuously flows into the treatment tank 31, resulting in part of the waste gas being discharged into the atmosphere before being fully burned, reducing the treatment quality of the waste gas by this device, and at the same time avoiding that when the output of the waste gas increases, the pressure of the waste gas on the pipeline continuously increases, resulting in the pipeline being under excessive pressure and being damaged, causing the waste gas to leak into the atmosphere. At the same time, part of the treated waste gas in the exhaust pipe 33 is guided into the heating shell 10 by the connecting pipe under the heating shell 10 to preheat the waste gas stored in the storage tank 2.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
