Description

Technical Field

[0001] The invention relates to the technical field of heat storage combustion, in particular to an industrial waste gas heat storage combustion device. Background Art

[0002] The current regenerative thermal combustion device (RTO) heats the organic waste gas discharged from production through the regenerative ceramics, and the temperature is rapidly raised. Under the heating effect of the combustion of gas in the furnace, the temperature reaches 680-1050℃. The VOCs in the organic waste gas are directly decomposed into carbon dioxide and water vapor at this high temperature, forming odorless high-temperature flue gas, which then flows through the low-temperature regenerative ceramics. A large amount of heat energy is transferred from the flue gas to the regenerative body to heat the organic waste gas to be decomposed in the next cycle. The temperature of the high-temperature flue gas itself drops significantly, and then heat is exchanged with other media through the heat recovery system. The flue gas temperature is further reduced and finally discharged to the outdoor atmosphere. It has the advantages of low operating costs, high efficiency in treating organic waste gas, and no catalyst poisoning. Therefore, this method is widely used in VOCs treatment of more advanced equipment in the world.

[0003] In the current existing technology, when waste gas is generally treated and burned, it is first necessary to preheat the waste gas. When it reaches a certain temperature, the waste gas is decomposed into carbon dioxide, water vapor and combustible waste gas. Then the combustible gas is ignited by an igniter. As the combustion proceeds, the waste gas is directly treated, and the increase in the heat of the waste gas can also help it to burn more efficiently. However, at present, the heat storage body needs to use electric energy or natural gas to externally intervene and heat the heat storage body in the initial state in the initial stage. This method will undoubtedly consume a lot of energy and cannot achieve effective energy saving. In addition, the waste gas generally contains other impurities, which are easy to adhere to or clog the heat storage body during the waste gas treatment process of the heat storage body, resulting in reduced fluidity of the waste gas with long-term use of the equipment, and ultimately affecting the combustion effect of the waste gas. Therefore, an industrial waste gas heat storage combustion device is proposed to solve the above-mentioned problems. Summary of the invention

[0015] Compared with the prior art, the present invention provides an industrial waste gas heat storage combustion device, which has the following beneficial effects:

[0016] 1. The industrial waste gas heat storage combustion device can automatically rotate the heat storage body through the conversion device when the combustion device is running, so that it is in a vertical state, which is convenient for the input of waste gas to decompose and burn. When the equipment stops running, it will automatically control the heat storage body to reset the angle so that its vertical position fits the closed sleeve.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 8 An industrial waste gas heat storage combustion device includes a furnace body 1, wherein a combustion chamber and three decomposition chambers are arranged in the furnace body 1, and the three decomposition chambers are all equipped with heat storage bodies 8, and the heat storage bodies 8 generally adopt ceramic heat storage bodies in the prior art; the bottom of the furnace body 1 is connected to a base 7, and an exhaust gas inlet pipe 5 is arranged inside the base 7, and the exhaust gas inlet pipe 5 is interconnected with the three decomposition chambers through three pipelines, and control valves are arranged on the pipelines, and one end of the exhaust gas inlet pipe 5 is connected to a fan 3, and the fan 3 is used to absorb the exhaust gas and transport it to the inside of the decomposition chamber and the combustion chamber through the pipeline. The internal cooling module cools down the gas to be discharged at this time, and the prior art generally adopts the spray cooling method. The technical solution does not limit the structure of the cooling module, and it is sufficient to cool the exhaust gas before discharging it. The combustion chamber in this technical solution is located above the heat storage body 8 in the furnace body 1, and the three decomposition chambers share one combustion chamber. The exhaust gases from the three decomposition chambers pass through the heat storage body 8 in turn, and after being processed and decomposed, they enter the common combustion chamber. The igniter ignites the combustible gas inside, and the combustion chamber is located below the cavity 401. The cavity 401 is filled with an aqueous solution, and the high temperature generated by the combustion in the combustion chamber is used to heat the aqueous solution.

[0030] In this embodiment, the conversion device 6 is used to automatically change the position of the heat storage body 8 to perform closed energy storage.

[0031] Furthermore, the conversion device 6 includes a pressure plate 601, one side of the pressure plate 601 is fixedly connected to an insertion shaft 603, the insertion shaft 603 is slidably connected to the exhaust gas inlet pipe 5, a first spring 604 is arranged between the pressure plate 601 and the exhaust gas inlet pipe 5, the pressure plate 601 is slidably connected to the inside of the base 7, and a support plate 605 is fixedly connected to the pressure plate 601. The exhaust gas is sucked by the fan 3 and discharged from the position of the base 7, and then the air pressure will push the pressure plate 601 to move horizontally, and then after sliding into the large-diameter hole groove inside the base 7, the exhaust gas will enter the interior of the exhaust gas inlet pipe 5 from the large-diameter hole groove. A sliding sheet 602 is fixedly connected to the support plate 605, and the sliding sheet 602 is slidably connected to the inside of the base 7. A sliding sleeve 608 is connected to the top of the support plate 605. A rotating shaft 606 is rotatably connected inside the furnace body 1. A spiral groove 607 is provided on the surface of the rotating shaft 606 located outside the furnace body 1. A sliding pin 609 is fixedly connected to the sliding sleeve 608, and the end of the sliding pin 609 is slidably connected to the inside of the spiral groove 607. Three heat storage bodies 8 are all arranged on the rotating shaft 606, and the two side surfaces of the heat storage bodies 8 are abutted with closed sleeves 701, and the closed sleeves 701 are fixed on both sides of the furnace body 1. And when the pressure plate 601 slides laterally due to air pressure, it will also drive the sliding of the support plate 605, and then drive the sliding pin 609 on the sliding sleeve 608 to slide on the spiral groove 607, and then use the spiral structure to drive the rotating shaft 606 to rotate 90 degrees, and convert the heat storage body 8 into a vertical state, which is convenient for gas circulation. When the equipment is closed, the pressure plate 601 is not subjected to air pressure, so it is reset by the elastic force of the first spring 604, and will slide through the connection of the spiral groove 607 to control the vertical pores of the heat storage body 8 to fit with the sealing sleeve 701, thereby protecting the pores from dust ingestion and ensuring that the internal temperature does not dissipate quickly.

[0032] Furthermore, the treatment device 4 is used to recover the energy of the exhaust gas in the furnace body 1 and to perform pressure recoil cleaning on the internal heat storage body 8; the treatment device 4 includes a cavity 401, which is arranged at the top of the furnace body 1, and the top of the furnace body 1 is located inside the cavity 401 and is provided with a heat conducting sheet 402, and the furnace body 1 is provided with a water supply pipe 403 connected to the cavity 401. During the operation of the equipment, as the internal aqueous solution is consumed, a certain amount of aqueous solution can be injected through the water supply pipe 403 using a water pipe, and the equipment needs to be closed at this point. The interior of the cavity 401 is provided with an aqueous solution. When the exhaust gas is burned in the combustion chamber, a certain high temperature will be generated on the furnace top, and the technical solution can use the high temperature at this time to heat the aqueous solution inside the cavity 401, thereby heating it to a steam state, so the overall high temperature is used to generate steam energy, which is then converted into mechanical energy, and finally the conversion and storage of electrical energy is realized.

[0033] In addition, the cavity 401 is connected with a steam pipe 404, one end of which is connected to a bellows 405, the inside of the bellows 405 is rotatably connected to a power shaft 407, the power shaft 407 is fixedly connected to an impeller 406, the bellows 405 is provided with a steam exhaust port, one end of the power shaft 407 is connected to a generator 422 via a crankshaft 408, and the generator 422 is electrically connected to a battery 424 via a wire 423. The steam generated by the combustion will be conducted to the inside of the bellows 405 through the steam pipe 404, and then drive the rotation of the impeller 406, and then the steam will be discharged from the outlet on the other side of the bellows 405, and the power generated by the rotation of the impeller 406 will drive the generator 422 to rotate, and the kinetic energy will be converted into electrical energy by using the principle of cutting the magnetic flux lines inside, and then transmitted to the inside of the battery 424 through the wire 423 for electrical energy storage.

[0034] In addition, the crankshaft 408 is rotatably connected with a first connecting rod 410, the top of the first connecting rod 410 is rotatably connected with a second connecting rod 411, the top of the second connecting rod 411 is connected with a piston plate 412, the surface of the piston plate 412 is slidably connected with a sleeve 413, the interior of the sleeve 413 is provided with a compression chamber 409, the top of the sleeve 413 is connected with an air intake pipe 414, the surface of the sleeve 413 is connected with a fixed air sleeve 418 through an air pipe, both the air pipe and the air intake pipe 414 are provided with a one-way valve, and the fixed air sleeve 418 is provided with a pressure cleaning device. The pressure cleaning device includes a sliding air sleeve 419, one end of which is slidably connected to the interior of the fixed air sleeve 418, the sliding air sleeve 419 is connected with a connecting pipe 420, the bottom of the connecting pipe 420 is connected with an arc sleeve 421, and the bottom of the arc sleeve 421 abuts against the heat storage body 8. The back-blowing is performed by high pressure. In actual process, the power shaft 407 receives the power of steam and drives the crank shaft 408 to rotate, thereby driving the first connecting rod 410 connected thereto to present an up-and-down movement. Then, the first connecting rod 410 drives the piston plate 412 on the second connecting rod 411 to slide up and down inside the sleeve 413. Each time it moves down, air will be sucked in from the mouth of the air inlet pipe 414, and then enter the compression chamber 409. As the piston plate 412 moves up, the gas will be squeezed and then transported to the fixed air sleeve 418 and the plurality of sliding air sleeves 419 through a pipeline, and then transmitted to the interior of the arc sleeve 421 through the connecting pipe 420. Therefore, a certain air pressure will be generated inside the arc sleeve 421 when it moves. Therefore, each time it moves, when it reaches between two rows of pores, the arc sleeve 421 is closed, the piston plate 412 compresses the gas, and air pressure is generated inside. Then, as the arc sleeve 421 gradually slides to the pore position of the heat storage body 8, the air pressure is instantly released, and the pores in that row are pressurized and back-blown.

[0035] It is worth noting that the arc sleeve 421 is connected with a sliding connecting rod 417, one end of the power shaft 407 is connected with a rotating shaft 415, and the top of the sliding connecting rod 417 is slidably connected to the inside of the gyroscopic groove 416 opened on the surface of the rotating shaft 415. The surface of the rotating shaft 415 is slidably connected with an air plate 425, which is fixed on the sliding air sleeve 419. When the sliding air sleeve 419 moves left and right, it also drives the lateral movement of the air plate 425. The air plate 425 is similar to a traditional blower, and the movement of the air plate 425 is used to blow the internal exhaust gas, thereby ensuring the internal exhaust gas is fully burned. A ventilation groove is opened on the air plate 425. When the steam drives the power shaft 407 to rotate, the power shaft 407 will also drive the rotating shaft 415 to rotate. Then, using the revolving groove 416 similar to a reciprocating screw opened on the surface, the sliding connecting rod 417 will reciprocate left and right on its surface, and then drive the arc sleeve 421 to slide and clean the upper surface of the heat storage body 8.

[0036] In addition, a partition 610 is installed inside the furnace body 1, and a baffle 614 is slidably connected to the side of the partition 610. The baffle 614 is fixedly connected to a pressing plate 612 through a connecting piece. The bottom of the pressing plate 612 is connected to a second spring 613. Through the second spring 613, when there is no air pressure from bottom to top, the pressing plate 612 will close the channel there. The bottom of the second spring 613 is connected to the bottom of the furnace body 1. A connecting hole 615 is opened on the partition 610. The bottom of the partition 610 is connected to an outlet pipe 611, and one end of the outlet pipe 611 is connected to the exhaust pipe 2. With the set pressing plate 612, the air pressure will go downward, controlling the pressing plate 612 to close the air inlet channel, so when the exhaust gas is exhausted from top to bottom, it will be discharged from the channel of the connecting hole 615 and will not enter the channel at the bottom of the pressing plate 612. Otherwise, part of the exhaust gas after combustion may enter the inside of the exhaust gas inlet pipe 5 from the channel, causing gas mixing. The connecting hole 615 is connected on one side, and is not in a left-right penetrating state on the partition 610, but is connected on the left and bottom. When the exhaust gas enters one decomposition chamber for decomposition, the burning gas will pass through the other two decomposition chambers, and then be discharged from another connecting hole 615, entering the interior of the exhaust pipe 611 to discharge the gas. Therefore, when one decomposition chamber takes in air, the other two decomposition chambers will realize the exhaust process.

[0037] In addition, two baffles 614 are provided, and the bottom of each baffle 614 is connected to the exhaust pipe 2. The side of the furnace body 1 is connected to the exhaust pipe 2 through a pipeline, and a cooling module is provided inside the exhaust pipe 2. Because the entire device is divided into three decomposition chambers, when one decomposition chamber is in the process of exhausting waste gas, the other two decomposition chambers will be in the process of exhausting, and the combustion waste gas inside the two decomposition chambers will be discharged respectively by connecting the pipeline. The decomposition chambers share a combustion chamber, and the igniter is located in the middle position. When the waste gas is decomposed, the igniter will ignite the combustible gas, and the generated waste gas will pass through the other two heat storage bodies 8, heating them while being discharged through their channels.

[0038] Working principle: first, when the equipment is in operation, it needs to rely on the fan 3 to suck the exhaust gas and discharge it from the position of the base 7. Then the air pressure will push the pressure plate 601 to move horizontally. After that, after sliding into the large-diameter hole groove inside the base 7, the exhaust gas will enter the exhaust gas inlet pipe 5 from the large-diameter hole groove. Three channels are set on the exhaust gas inlet pipe 5, corresponding to the three heat storage bodies 8 respectively. At this time, the exhaust gas enters the decomposition chamber, and only one channel needs to be opened, so the other two channels are closed through the control valve. After that, the exhaust gas enters the decomposition chamber from one channel, and the air pressure will also push up the pressure plate 612, and the exhaust gas will enter the heat storage body. 8, and at this time the temperature of the heat storage body 8 must be very high, so that the waste gas can be decomposed at high temperature, and then the waste gas goes up into the combustion chamber, and the internal igniter of the combustion chamber is used to burn the decomposed combustible gas, and the burned waste gas will enter from the other two decomposition chambers, and the waste gas can also heat the other two heat storage bodies 8, and then pass through the other two heat storage bodies 8 and enter the inside of the outlet pipe 611 from the connecting hole 615 on the second partition 610, and then guide it into the inside of the exhaust pipe 2, and cool the gas to be discharged at this time through the internal cooling module. In the prior art, spray cooling is generally used. This technical solution does not limit the structure of the cooling module, and it can be discharged after cooling the waste gas. When the pressure plate 601 slides horizontally under the air pressure, it will also drive the support plate 605 to slide, and then drive the sliding pin 609 on the sliding sleeve 608 to slide on the spiral groove 607, and then use the spiral structure to drive the rotating shaft 606 to rotate 90 degrees, converting the heat storage body 8 to a vertical state, which is convenient for the circulation of gas. When the equipment is closed, the pressure plate 601 is not subjected to air pressure, so it is reset by the elastic force of the first spring 604, and it will slide through the connection of the spiral groove 607 to control the vertical pores of the heat storage body 8 to fit with the sealing sleeve 701, thereby protecting the pores from dust ingestion and ensuring that the internal temperature will not dissipate quickly. Because when the equipment is not turned on, it is generally necessary to add natural hot air to initially heat up the heat storage body 8, or electric heating elements, to heat up the heat storage body 8, which requires a lot of energy, so the device can automatically convert the position of the heat storage body 8 after the last equipment operation is stopped, so that it is in a closed state, so the heat energy consumption will be reduced at this time, and when it is turned on later, the energy consumed will be reduced.When the exhaust gas burns in the combustion chamber, a certain high temperature will be generated on the furnace top. In this technical solution, the high temperature at this time can be used to heat the aqueous solution inside the cavity 401, thereby heating it to a steam state. The generated steam will pass through the steam pipe 404 to conduct the steam to the inside of the bellows 405, and then drive the rotation of the impeller 406. After that, the steam will be discharged from the outlet on the other side of the bellows 405, and the power generated by the rotation of the impeller 406 will drive the generator 422 to rotate. The kinetic energy is converted into electrical energy by utilizing the principle of internal cutting of magnetic flux lines, and is transmitted to the inside of the battery 424 through the wire 423 for electrical energy storage. Subsequent equipment can use the electrical energy there for heat storage when it is turned on. At the same time, the electrical energy accumulated in the battery 424 can also be used to consume energy for other electrical appliances, ultimately realizing the energy conversion and storage during the combustion of exhaust gas. The principle of the steam generator is utilized as a whole, and the heat generated by the combustion of exhaust gas is converted into steam, and then the steam is converted into mechanical energy, and the mechanical energy is converted into electrical energy, ultimately realizing the energy conversion and residual energy absorption. At the same time, when the steam drives the power shaft 407 to rotate, the power shaft 407 will also drive the rotating shaft 415 to rotate, and then the sliding connecting rod 417 will reciprocate on the left and right positions on its surface by using the revolving groove 416 similar to the reciprocating screw opened on the surface, and then drive the arc sleeve 421 to slide and clean the upper surface of the heat storage body 8. The traditional method also has back-blowing cleaning. For example, when the first heat storage body 8 decomposes the exhaust gas, the airflow of the other two heat storage bodies 8 will be from top to bottom at this time, so the airflow will heat up the other two heat storage bodies 8 while also back-blowing the internal pores. When the second heat storage body 8 is in the process of decomposing the exhaust gas, the other two heat storage bodies 8 will be in the same process as above, and the airflow will back-blow, and finally achieve cleaning. However, this method of cleaning relies on the natural flow back-blowing cleaning after the exhaust gas is burned, so the cleaning effect is not good. In this technical solution, back-blowing is performed by high pressure. The actual process is that the power shaft 407 receives the power of steam and drives the crankshaft 408 to rotate, thereby driving the first connecting rod 410 connected thereto to move up and down. Then, the first connecting rod 410 drives the piston plate 412 on the second connecting rod 411 to slide up and down inside the sleeve 413. Each time it moves down, air is sucked in from the mouth of the intake pipe 414, and then enters the compression chamber 409. As the piston plate 412 moves up, the gas is squeezed and then transported out through the pipeline. It is sent to the interior of the fixed air sleeve 418 and multiple sliding air sleeves 419, and then transmitted to the interior of the arc sleeve 421 through the connecting pipe 420. Therefore, a certain air pressure will be generated inside the arc sleeve 421 when it moves. Therefore, each time it moves, when it reaches between two rows of pores, the arc sleeve 421 is closed, and the piston plate 412 compresses the gas to generate air pressure inside. Then, as the arc sleeve 421 gradually slides to the pore position of the heat storage body 8, the air pressure is released instantly at this time, and the pores in this row will be pressurized and backblown to ensure that the internal pores will not be attached by impurities.After the first heat storage body 8 has worked for a certain period of time, by changing the opening and closing of the control valve, the waste gas in the waste gas inlet pipe 5 enters the second decomposition chamber from the second channel position. The waste gas burned by the same principle will pass through the other two heat storage bodies 8, and while heating them, they can also be cleaned in a traditional way. After that, the waste gas will enter the outlet pipe 611 from the position of the connecting hole 615 and continue to be discharged from the exhaust pipe 2. With the set pressing sheet 612, the air pressure will go down, and the pressing sheet 612 will be controlled to close the air inlet channel. Therefore, when the waste gas is exhausted from top to bottom, it will be discharged from the channel of the connecting hole 615 and will not enter the channel at the bottom of the pressing sheet 612. Otherwise, a part of the burned waste gas may enter the interior of the waste gas inlet pipe 5 from the channel, causing gas mixing.
