Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment equipment, and in particular relates to a heat storage type waste gas incineration system. Background Art

[0002] In today's society, waste gas pollution is serious, and effective waste gas treatment has become a top priority in the environmental protection industry. As one of the important means of treating organic waste gas, incineration has high treatment efficiency, but it occupies a large area, requires large investment, and has high requirements for operational safety and technology. Therefore, how to maintain and carry forward its advantages and improve and overcome its shortcomings is something we need to explore in depth.

[0003] RTO (Regenerative Thermal Oxidizer) is a highly efficient organic waste gas (VOC) treatment equipment. Compared with traditional catalytic combustion and direct-fired thermal oxidizers (TO), it has the characteristics of high thermal efficiency (≥95%), low operating cost, and the ability to handle large air volume and low-concentration waste gas. When the concentration is slightly higher, secondary waste heat recovery can also be performed, greatly reducing production and operation costs.

[0004] Regenerative thermal incinerators can treat toxic gases (HAPs), volatile organic gases (VOCs) and odors emitted from industrial processes. The RTO system uses high-temperature oxidation to remove waste gas, converts waste gas into carbon dioxide and water vapor by controlling temperature, residence time, turbulence and oxygen volume, and recovers the heat released when the waste gas is decomposed, thereby achieving the dual purpose of environmental protection and energy saving.

[0005] Nowadays, the regenerative chambers in regenerative thermal oxidizers mostly adopt a multi-tower chamber method and a rotary RTO. In the multi-tower chamber method, the regenerative chambers are connected in parallel, and the airflow direction changes 180° in the combustion chamber, which increases the flow resistance of the organic waste gas in the RTO. The rotary RTO requires an additional motor, and the airflow direction changes 180° in the combustion chamber, which increases the gas flow resistance and makes the overall volume larger and occupies a large space.

[0006] Moreover, each regenerator of the existing multi-tower regenerative thermal oxidation furnace must participate in preheating or cooling, which leads to problems such as problems in one of the regenerators or blockage of the ceramic regenerator. Basically, the entire equipment must be stopped for maintenance. If it is not repaired, the problem of the blocked or problematic regenerator will be aggravated, and the energy saving efficiency will also be reduced. In addition, there is also the problem of inflexible use of the equipment structure. Summary of the invention

[0007] The purpose of the present invention is to provide a heat storage type waste gas incineration system, which can avoid the problem that one of the heat storage chambers has problems and needs maintenance without affecting the entire heat storage system, and the processing gas path can be switched, which is more flexible and convenient.

[0012] Among the at least two heat storage chambers opposite to the combustion chamber, at least one heat storage chamber is used for air intake, and the remaining heat storage chambers are used for air exhaust to form a processing gas path.

[0013] In a possible implementation, the partition component includes a rotating shaft rotatably connected to the center of the oxidation combustion chamber and at least one partition plate connected to the rotating shaft in a centrally symmetrical manner. Each partition plate constitutes the partition portion, and both ends of the partition plate are slidably sealed with the inner wall of the oxidation combustion chamber.

[0019] One end of the air outlet pipeline is a clean air inlet end and is respectively connected to the air outlet of each of the heat storage chambers, and the other end is a clean air discharge end and is connected to the chimney.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Please refer to Figure 1-4 As shown, an embodiment of the present application provides a regenerative waste gas incineration system, including a regenerative incineration device 1; the regenerative incineration device 1 includes a shell, a cylindrical oxidation combustion chamber 12 and an even number of regenerative chambers 11 arranged around the oxidation combustion chamber 12 are provided in the shell, the regenerative chambers 11 are communicated with the oxidation combustion chamber 12, and each of the regenerative chambers 11 has an air inlet and an air outlet, and each air inlet and each air outlet is provided with a valve.

[0037] The oxidation combustion chamber 12 in the shell is cylindrical, and an even number of heat storage chambers 11 are arranged around the outer side of the oxidation combustion chamber 12, specifically an even number greater than 2, so that each combustion chamber corresponds to two heat storage chambers 11; the oxidation combustion chamber 12 is used to burn gas to oxidize and decompose volatile organic compounds (VOCs) and toxic gases (HAPs) and odor to form pure gas, and these exhaust gases enter through the air inlet of the heat storage chamber 11, and pass through the heat storage ceramics of the heat storage chamber 11 to the oxidation combustion chamber 11. The pure gas after oxidation and decomposition in the oxidation combustion chamber 12 passes through another heat storage chamber 11 and leaves from the gas outlet of the heat storage chamber 11, and the heat storage ceramics of the heat storage chamber 11 pass through absorb the heat of the high-temperature exhaust gas after combustion, so that the temperature of the high-temperature exhaust gas drops and the heat is recovered, thereby realizing the treatment of the exhaust gas; by arranging valves at the air inlet and outlet of each heat storage chamber 11, it can be more convenient to control, and the opening and closing combination of the valves can also be used to realize forward and reverse switching processing.

[0038] The oxidation combustion chamber 12 is provided with a partition component that can rotate around its axis. The partition component has at least one partition part and the oxidation combustion chamber 12 is divided into at least two combustion chambers through the partition part. Each combustion chamber corresponds to two heat storage chambers 11 and is connected to each heat storage chamber 11. Among them, the partition component can separate the oxidation combustion chamber 12 into at least two combustion chambers, and each combustion chamber is connected to the corresponding multiple heat storage chambers 11, so that a structure of one combustion chamber corresponding to multiple combustion chambers can be formed, and the positional relationship is basically adjacent to each other up and down or left and right. Such a positional relationship can greatly reduce the gas flow resistance that changes 180° in the combustion chamber. The partition component is set to be rotatable, which can facilitate the flexible adjustment of the use of the heat storage chamber 11 according to actual conditions.

[0039] In at least two heat storage chambers 11 opposite to the combustion chamber, at least one heat storage chamber 11 is used for air intake, and the remaining heat storage chambers 11 are used for air outlet to form a processing gas path. There are only two processing gas paths, which are specifically determined by the number of partitions of the partitioning component, and multiple processing gas paths can avoid problems in one of the heat storage chambers 11 that require maintenance without affecting the entire heat storage system. In a processing gas path, since one heat storage chamber 11 needs to take in air and the other needs to exhaust air, the valve of the air inlet or outlet needs to be set to be closed or opened accordingly.

[0040] Through the above technical solution, the oxidation combustion chamber 12 can be equipped with multiple heat storage chambers 11, and can form at least two independent processing gas paths. The two adjacent gas paths can also be switched with each other, so that when a problem occurs in one of the gas paths or the heat storage chamber 11 in one gas path and needs maintenance, there is no need to stop the operation of the entire system to maintain the treatment of the exhaust gas. In addition, in one processing gas path, the exhaust gas enters the oxidation combustion chamber after passing through a heat storage chamber 11, and the high-temperature gas after combustion can be directly discharged from another heat storage chamber 11. When switching directions, it can be done with smaller flow resistance. At the same time, the entire structure is simple, the failure rate is low, the footprint is small, and it has a high thermal energy utilization rate.

[0041] In one embodiment, the partition component includes a rotating shaft rotatably connected to the center of the oxidation combustion chamber 12 and at least one partition plate 13 connected to the rotating shaft in a centrally symmetrical manner. Each partition plate 13 constitutes the partition portion, and both ends of the partition plate 13 are slidably sealed with the inner wall of the oxidation combustion chamber 12.

[0042] The partition plate 13 is rotatably installed in the oxidation combustion chamber 12 through a rotating shaft, and is slidably sealed with the inner wall of the oxidation combustion chamber 12. This can not only ensure the sealing between multiple processing gas paths, but also facilitate the flexible switching of the heat storage chamber 11 corresponding to the combustion chamber through the rotation of the partition plate 13 to adapt to different operating conditions.

[0043] In order to facilitate the control of the rotation of the partition component, the rotating shaft of the partition component is further connected with a driving device. The driving device can drive the rotating shaft to rotate, thereby rotating the partition plate 13. Specifically, the driving device uses a driving motor 15 and a reducer to drive the rotating shaft, and the driving device is arranged on the outside of the housing.

[0044] In the specific implementation process, combined with Figure 1 , Figure 3 and Figure 4 As shown, one partition plate 13 is provided on the rotating shaft and four are provided on the heat storage chamber 11, or one partition plate 13 is provided on the rotating shaft and six are provided on the heat storage chamber 11, or two partition plates 13 perpendicular to each other are provided on the rotating shaft and eight are provided on the heat storage chamber 11. The above three implementation structures are all feasible structures, and can realize multiple processing gas paths, with better processing efficiency and greater space utilization.

[0045] Specifically, the heat storage chamber 11 is a fan-shaped structure and a corresponding honeycomb ceramic bed 111 is arranged therein.

[0046] In an embodiment of the present application, the regenerative waste gas incineration system also includes an air inlet pipeline 2, an air outlet pipeline 4 and a chimney 5; one end of the air inlet pipeline 2 is a waste gas inlet end and is connected to a waste gas source, and the other end is a waste gas outlet end and is respectively connected to the air inlet of each of the regenerative chambers 11; a fan 3 is provided on the air inlet pipeline 2; one end of the air outlet pipeline 4 is a clean gas inlet end and is respectively connected to the air outlet of each of the regenerative chambers 11, and the other end is a clean gas discharge end and is connected to the chimney 5.

[0047] Among them, the air inlet pipeline 2 is used to transport the exhaust gas, and is transported to the heat storage chamber 11 through the air inlet of each heat storage chamber 11, which is specifically powered by the fan 3; and the air outlet pipeline 4 is used for clean gas output, which is connected to the air outlet of the heat storage chamber 11, so that the clean gas generated by the heat storage incineration device 1 can be transported to the chimney 5 and discharged through the chimney 5.

[0048] In one embodiment, the exhaust gas outlet end of the air inlet pipe 2 and the clean gas inlet end of the air outlet pipe 4 are simultaneously connected to a switching valve 6, the switching valve 6 has a first outlet and a second outlet, the first outlet is connected to the air inlet of the heat storage chamber 11 through a first connecting pipe 7, and the second outlet is connected to the air outlet of the heat storage chamber 11 through a second connecting pipe 8; the switching valve 6 has a first connected state and a second connected state; in the first connected state, the exhaust gas outlet end of the air inlet pipe 2 is connected to the first connecting pipe 7, and the clean gas inlet end of the air outlet pipe 4 is connected to the second connecting pipe 8; in the second connected state, the exhaust gas outlet end of the air inlet pipe 2 is connected to the second connecting pipe 8, and the clean gas inlet end of the air outlet pipe 4 is connected to the first connecting pipe 7.

[0049] In this way, by switching valve 6, the direction of each processing gas path can be reversed, so that new exhaust gas can enter the oxidation combustion chamber from the heat storage chamber 11 with high energy after heat storage, and the high-temperature exhaust gas after combustion leaves from another heat storage chamber 11. At the same time, the heat storage chamber 11 absorbs the heat of the exhaust gas after combustion to store heat and energy, so as to circulate. At the same time, it is also convenient to introduce clean gas for reverse gas cleaning, and the honeycomb holes blocked by the honeycomb ceramic bed 111 can be eliminated to a certain extent through reverse processing, so as to achieve the cleaning effect and extend the service life. At the same time, the system can be used in more working conditions and is more flexible.

[0050] It should be noted that the air inlet and the air outlet of the heat storage chamber 11 in the present technical solution are relative and not fixed, and are specifically determined by the role played in the forward or reverse processing gas path.

[0051] In other embodiments, the oxidizing combustion chamber 12 is equipped with a combustion system 14; the combustion system 14 includes combustion components corresponding to each of the combustion chambers; the combustion components include a burner 141 connected to a fuel gas source and combustion-supporting air.

[0052] The combustion component can burn the exhaust gas in the oxidation combustion chamber 12.

[0053] In the embodiment of the present application, the partition plate 13 is mainly made of heat-conducting material.

[0054] The partition plate 13 is made of heat-conducting material, which allows the heat of adjacent combustion chambers to be transferred to each other, thereby facilitating mutual insulation and heat-cooling effects of the combustion chambers, thereby reducing the use of gas and being more environmentally friendly.

[0055] In some embodiments, the thermal storage waste gas incineration system may also include a waste gas pretreatment device arranged at the front end of the thermal storage incineration device 1. The device may include pretreatment equipment such as a waste gas water washing tower, a gas-liquid separator and / or a waste gas alkali washing tower. At the rear end of the thermal storage incineration device 1, a device that is convenient for utilizing the clean gas that still has heat for heat exchange, such as an absorption heat pump, can be arranged to make greater use of the heat energy generated in the process, which is more practical and environmentally friendly.

[0056] Of course, it can also be equipped with a high-temperature emergency discharge pipeline. When the exhaust gas concentration exceeds the lower explosion limit of 25%, the exhaust gas needs to be discharged urgently. The valve at the air inlet is closed, the emergency discharge valve is opened, the fan 3 is turned off, and the exhaust gas is pulled by the induced draft fan 3. The exhaust gas is first adsorbed by the activated carbon adsorption device, and then washed by the alkali solution spray absorption tower before being discharged into the atmosphere through the chimney 5 to avoid substandard exhaust gas emission standards during emergency discharge.

[0057] The working principle of a thermal storage type waste gas incineration system in the embodiment of the present application is as follows:

[0058] First, the forward processing gas path is operated, and the exhaust gas is transported through the air intake pipe 2 and the fan 3, and after passing through the switching valve 6, enters the corresponding heat storage chamber 11 through the air inlet of the heat storage chamber 11 used for air intake in a processing gas path. The exhaust gas is preheated when passing through the heat storage chamber 11, and the burner 141 of the oxidation combustion chamber can realize combustion therein after mixing natural gas with combustion-supporting air, and the temperature of the oxidation combustion chamber is maintained at about 850°. In this process, the exhaust gas can be oxidized into pure gas, such as carbon dioxide and water vapor. The pure gas is high-temperature gas, and the high-temperature gas after combustion leaves from another heat storage chamber 11. When passing through the heat storage chamber 11, the heat storage ceramics therein will absorb the heat of the high-temperature gas after combustion, so that its temperature is reduced, and the heat is recovered, and then it is discharged through the air outlet of the heat storage chamber 11, and finally it can be discharged into the atmosphere through the chimney 5.

[0059] When it is necessary to perform reverse operation on the gas processing path, the switching is performed through the switching valve 6, and the exhaust gas enters from the heat storage chamber 11 originally used for exhaust, and then leaves from the heat storage chamber 11 originally used for intake. During the leaving process, the heat storage ceramic in the leaving heat storage chamber 11 can store heat and energy, thus forming a cycle.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
