Description
Technical Field
[0001] The invention relates to the field of waste gas treatment, and in particular to an RTO thermal storage incineration device and a combustion method. Background Art
[0002] RTO regenerative thermal oxidizer is a highly efficient organic waste gas treatment equipment. Its principle is to oxidize combustible waste gas into corresponding oxides and water at high temperature, thereby purifying the waste gas and recovering the heat released when the waste gas is decomposed. The waste gas decomposition efficiency reaches more than 99%, and the heat recovery efficiency reaches more than 95%. The main structure of RTO consists of a combustion chamber, a ceramic packing bed and a switching valve. According to the actual needs of customers, different heat recovery methods and switching valve methods are selected. The regenerative thermal incinerator uses thermal oxidation to treat low and medium concentration organic waste gas, and uses a ceramic regenerative bed heat exchanger to recover heat. It consists of a ceramic regenerative bed, an automatic control valve, a combustion chamber and a control system. Its main features are: the automatic control valve at the bottom of the heat storage bed is connected to the intake main pipe and the exhaust main pipe respectively; the heat storage bed is alternately switched through the reversing valve to store the heat of the high-temperature gas coming out of the combustion chamber and preheat the organic waste gas entering the heat storage bed; ceramic heat storage materials are used to absorb and release heat; the organic waste gas preheated to a certain temperature (≥760℃) undergoes oxidation reaction in the combustion chamber to generate carbon dioxide and water and is purified.
[0003] The patent application with announcement number CN207648818U is a high-efficiency RTO heat storage incinerator, including a device shell, a combustion chamber, a cleaning chamber, a heating chamber, a cooling chamber, and a fan. The combustion chamber device shell is provided with a combustion port, and an auxiliary burner is provided on the outer side of the device shell opposite to the combustion port. A heating chamber is provided below the combustion chamber, and a cleaning chamber and a cooling chamber are provided on both sides of the heating chamber. A bracket is provided below the device, and a fan is provided on the right side of the device. The fan is connected to the air inlet pipe, and an air outlet pipe is provided on the left side of the device. The air inlet pipe and the air outlet pipe are respectively connected to the cleaning chamber, the heating chamber, the cooling chamber, and the combustion chamber, and each pipe is provided with a switching valve. The utility model has high thermal shock resistance and stability, can adapt to environments with large temperature changes and the presence of corrosive gases and long-term stress caused by huge temperature differences, reduce thermal stress, avoid deformation of the heat storage body, increase the service life of the device, reduce heat loss, strengthen waste heat utilization, and reduce resource consumption.
[0004] The existing RTO heat storage incineration device is provided with three groups of heat storage spaces. When working, one group of spaces is responsible for air transportation, one group is responsible for output, and the last group of spaces needs to discharge the waste gas containing residual temperature back into the combustion chamber, so as to mix with the new waste gas for combustion. The space where the waste gas is discharged here is the space responsible for discharge in the previous cycle. In this process, the heat in the waste gas heats the ceramic heat storage tube, and the work is performed reciprocatingly in this way. However, the existing waste gas transportation method is carried out by external blasting, and the connection between the blasting transportation and the incineration device is generally controlled by a valve to ensure the sealing inside the incineration device. However, in this way, after the waste gas enters the incineration device, its blasting effect is very small, resulting in low fluidity of the waste gas inside the incineration device, thereby reducing the overall efficiency of the waste gas treatment. Moreover, since the waste gas cannot interfere with its airflow during the combustion treatment process, the addition of a blast diversion method is obviously easy to interfere with the waste gas treatment process, causing airflow chaos or running around in the three groups of heat storage spaces.

[0040] The valve assembly 002 disposed in the heat storage space of the incinerator shell 001 includes a sealing cylinder 201, which is connected through the air supply pipe 104, the return air pipe 105 and the outlet pipe 106 and the through connection with the heat storage space, and the sealing cylinder 201 seals the connection, and a plurality of groups of through grooves 202 are arranged on the inner wall of the sealing cylinder 201 in an annular distribution, and the length of the sealing cylinder 201 at the air supply pipe 104 is greater than the sealing cylinder 201 at the return air pipe 105 and the outlet pipe 106, and the horizontal position of the through grooves 202 on the surface of the sealing cylinder 201 at the air supply pipe 104 is lower than the horizontal position of the through grooves 202 at the return air pipe 105 and the outlet pipe 106;
[0041] The through groove 202 on the surface of the sealing cylinder 201 at the position of the air supply pipe 104 is at a lower position, so that when the sealing cylinder 201 here moves upward a short distance, the through groove 202 will not be exposed from the connection, thereby ensuring the sealing while allowing the sealing cylinder 201 at the position of the air supply pipe 104 to move freely a short distance, and only after the sealing cylinder 201 moves upward and exposes the through groove 202, can the air supply pipe 104, the return air pipe 105 and the outlet pipe 106 work normally.
[0042] The driving assembly 003 disposed in the incinerator shell 001 includes a motor 301, which is installed on the top of the incinerator shell 001, and three groups of motors 301 are installed in sequence. A baffle 302 is installed above the inner wall of the three groups of heat storage spaces in the incinerator shell 001, and ventilation slots 307 are symmetrically opened on the surface of the baffle 302. A rotating shaft 303 is rotatably connected between the baffle 302 and the upper part of the inner wall of the incinerator shell 001, and the rotating shaft 303 is axially connected to the corresponding output end of the motor 301;
[0043] The motor 301 can drive the rotating shaft 303 to rotate, and the baffle 302 can ensure the sealing of the heat storage space, and the two groups of ventilation grooves 307 can ensure the communication between the heat storage space and the combustion chamber.
[0044] The air supply assembly 004 arranged in the incinerator shell 001 includes a connecting ring 401, which is symmetrically installed below the baffle 302, and the connecting ring 401 is connected with the corresponding ventilation groove 307. The limiting grooves 402 are symmetrically arranged on the inner wall of the connecting ring 401, and an annular mounting frame 403 is penetrated through the connecting ring 401. The limiting blocks 404 are symmetrically installed on the outer side of the annular mounting frame 403, and the limiting blocks 404 are slidably connected with the corresponding limiting grooves 402. A turbofan 405 is installed in the annular mounting frame 403.
[0045] Through the sliding connection between the limiting block 404 and the limiting groove 402 , the annular mounting frame 403 can drive the turbofan 405 to slide up and down within the connecting ring 401 for a short distance.
[0046] Furthermore, in the above structure, the valve assembly 002 also includes a connecting groove 203, which is opened below the inner wall of the three groups of heat storage spaces in the incinerator shell 001. An electric push rod 204 is installed in the connecting groove 203, and the output end of the electric push rod 204 is fixedly connected to the upper edge of the sealing tube 201, and the electric push rod 204 located at the air supply pipe 104 can be controlled in two gears.
[0047] The sealing cylinder 201 can be driven to move up and down by the electric push rod 204, and since the electric push rod 204 at the air supply pipe 104 can be controlled in two gears, when the first gear is controlled, the through groove 202 on the surface of the sealing cylinder 201 at the air supply pipe 104 will not be exposed from the connection, and the through groove 202 can only be exposed in the second gear control, thereby realizing the normal operation of the sealing cylinder 201.
[0048] Furthermore, in the above structure, the driving component 003 also includes a gear 1 304, which is sleeved and fixed on the rotating shaft 303, and a gear 2 305 is symmetrically rotatably connected on the baffle 302, and two groups of gears 2 305 are respectively located on both sides of the gear 1 304, and the two groups of gears 2 305 are respectively meshed with the gear 1 304.
[0049] The symmetrical meshing of the gear 2 305 and the gear 1 304 makes the rotation directions of the two sets of gear 2 305 just opposite.
[0050] Furthermore, in the above structure, sprocket one 306 is respectively sleeved and fixed on the two sets of gear two 305, a fixing frame 308 is installed on the inner wall of the ventilation slot 307, and a sprocket two 309 is rotatably connected above the fixing frame 308.
[0051] The sprocket wheel 1 306 can be driven to rotate by the gear wheel 2 305 , and the fixing frame 308 can ensure that the sprocket wheel 2 309 rotates in the ventilation slot 307 .
[0052] Furthermore, in the above structure, an anti-skid docking shaft 1 311 is rotatably connected below the fixing frame 308 , and the anti-skid docking shaft 1 311 is axially connected to the sprocket 2 309 , and a chain 310 is connected between the sprocket 1 306 and the sprocket 2 309 .
[0053] Through the chain 310, the sprocket wheel 1 306 can drive the sprocket wheel 2 309 to rotate, so that the anti-skid docking shaft 1 311 below rotates accordingly.
[0054] Furthermore, in the above structure, the air supply assembly 004 also includes a docking tube 406, which is rotatably connected above the annular mounting frame 403, and the docking tube 406 is axially connected to the turbofan 405, and positioning grooves 407 are symmetrically opened on the inner wall of the docking tube 406.
[0055] The turbofan 405 can be driven to rotate through the docking sleeve 406.
[0056] Furthermore, in the above structure, an anti-slip docking shaft 408 is connected through the docking tube 406, and the anti-slip docking shaft 408 is at the same horizontal position as the corresponding anti-slip docking shaft 311. A positioning block 409 is symmetrically installed on the anti-slip docking shaft 408, and the positioning block 409 is slidably connected to the corresponding positioning groove 407.
[0057] Through the cooperation between the positioning block 409 and the positioning groove 407 , the anti-skid docking shaft 408 can slide stably in the docking tube 406 .
[0058] Furthermore, in the above structure, a spring 410 is fittedly connected between the anti-slip docking shaft 408 and the docking tube 406, a docking rod 411 is installed under the annular mounting frame 403, and two sets of docking rods 411 are fixedly connected to the top of the sealing tube 201 at the corresponding air supply pipe 104 and the air outlet pipe 106, respectively.
[0059] The spring 410 can maintain the position of the anti-skid docking shaft 2 408 and the docking tube 406, and the sealing tube 201 can move upward to enable the docking rod 411 to push the annular mounting frame 403 to move, so that the anti-skid docking shaft 2 408 and the anti-skid docking shaft 1 311 are docked, so that the turbofan 405 rotates, and because the rotation directions of the two sets of anti-skid docking shafts 1 311 are just opposite, when the turbofan 405 above the air duct 104 rotates, the gas in the heat storage space can be transported to the combustion chamber, and the turbofan 405 above the exhaust pipe 106 rotates in the opposite direction, and the sealing tube 201 at the air duct 104 can ensure that the turbofan 405 rotates in two gears, so that when the return air duct 105 supplies air, the sealing tube 201 at the air duct 104 moves in one gear to ensure that it does not work itself, but can make the turbofan 405 above work, thereby realizing the airflow sent in by the auxiliary return air duct 105 and sending the residual exhaust gas into the combustion chamber.
[0060] A combustion method of an RTO thermal storage incinerator, comprising the above RTO thermal storage incinerator, wherein the specific processing steps are as follows:
[0061] S1: The exhaust gas is transported to the first heat storage space through the air delivery pipe 104 by the fan 102. At this time, the sealing cylinder 201 at the air delivery pipe 104 in the first heat storage space moves upward, so that the exhaust gas enters. Since the sealing cylinder 201 moves upward, the turbofan 405 is pushed and rotated, thereby accelerating the efficiency of the exhaust gas entering the upper combustion chamber;
[0062] S2: At this time, the waste gas with residual temperature remaining in the third heat storage space moves upward by a general distance through the sealing cylinder 201 at the air delivery pipe 104 in the second heat storage space, and at the same time, the return air pipe 105 blows air to blow out the residual waste gas at the same time, so that the two waste gases are mixed and burned in the combustion chamber;
[0063] S3: After the combustion is completed, the sealing cylinder 201 at the outlet pipe 106 in the second heat storage space moves upward, so that the corresponding turbofan 405 here rotates, thereby sucking in the exhaust gas after combustion, and heating the ceramic heat storage tube 108 in the second heat storage space at the same time, and finally discharging the exhaust gas through the chimney 107, thereby completing the entire incineration process.
[0064] like Figure 1-10 As shown, by conveying the exhaust gas to the first heat storage space through the fan 102, the sealing cylinder 201 at the position of the air delivery pipe 104 in the first heat storage space is fully opened, so that the exhaust gas can enter the first heat storage space. At this time, due to the upward movement of the sealing cylinder 201, the docking rod 411 pushes the annular mounting frame 403 to move upward, so that the anti-slip docking shaft 2 408 is docked with the anti-slip docking shaft 1 311, thereby completing the power transmission, so that the turbofan 405 rotates to convey the exhaust gas into the combustion chamber. At the same time, the exhaust gas remaining in the third heat storage space is blown back into the combustion chamber through the return air pipe 105. At the same time, the sealing cylinder 201 at the air delivery pipe 104 in the third heat storage space moves upward by half the distance, so that the turbofan 405 above the third heat storage space is opened, but the air delivery pipe 104 does not work, thereby assisting the residual exhaust gas to enter the combustion chamber. After the combustion process is completed, the sealing tube 201 at the outlet pipe 106 in the second heat storage space is opened, so that the turbofan 405 above rotates. The turbofan 405 here rotates in the opposite direction, so that the treated exhaust gas in the combustion chamber is quickly sucked in and discharged into the chimney 107 along the outlet pipe 106. In this way, the reciprocating cycle is completed to complete the entire combustion process. During this process, the ceramic heat storage tube 108 will recover the heat energy of the high-temperature gas. Through this structure, the kinetic energy generated when the air supply pipe 104, the outlet pipe 106 and the return air pipe 105 are opened can be used to control the rotation of the turbofan 405 at the corresponding position, which not only assists the flow of exhaust gas but also ensures that the corresponding position can be controlled in time. The three groups of heat storage spaces and the combustion chamber can be non-interfering with each other without affecting the work, thereby improving the overall exhaust gas treatment efficiency.
[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
