Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a three-tower RTO environmentally friendly thermal storage waste gas treatment equipment. Background Technology

[0002] Waste gas treatment is a crucial part of industrial production, especially in industries such as chemical, pharmaceutical, and coating, which generate large amounts of waste gas containing volatile organic compounds. The three-tower RTO environmentally friendly thermal storage waste gas treatment equipment is a highly efficient organic waste gas treatment device, mainly used to treat waste gas containing volatile organic compounds generated during industrial production.

[0003] Traditional three-tower RTO (Regenerative Thermal Oxidizer) environmental protection waste gas treatment equipment suffers from a fixed internal ceramic heat storage element position during operation. This position cannot be adjusted in real time according to changes in waste gas flow rate and composition. Consequently, the heat exchange efficiency between the waste gas and the ceramic heat storage element decreases when the waste gas flow rate or composition changes, affecting the overall thermal efficiency and purification efficiency of the equipment. Therefore, those skilled in the art have provided a three-tower RTO environmental protection waste gas treatment equipment to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a three-tower RTO (Regenerative Thermal Oxidizer) environmentally friendly heat storage waste gas treatment device. Through an adjustment device, it can adjust the height and position of the ceramic heat storage body in real time according to changes in waste gas flow and composition, optimize heat exchange efficiency, extend the residence time of waste gas in the heat storage chamber, and ensure the full oxidation and decomposition of organic matter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-tower RTO environmentally friendly heat storage waste gas treatment device, comprising a body and a burner. The burner is located at the upper center of the rear end face of the body. A first heat storage chamber is located at one side of the center of the lower end face of the body. A second heat storage chamber is located at the center of the lower end face of the body. A third heat storage chamber is located at the other side of the center of the lower end face of the body. A high-pressure blower is located at one side of the lower end of the third heat storage chamber. A waste gas conveying pipe is located at the output end of the high-pressure blower. A cleaning pipe is located at the rear center of the lower end of the second heat storage chamber. A purified air conveying pipe is located at the center of the lower end of the second heat storage chamber. An exhaust pipe is located at the output end of the purified air conveying pipe. Ceramic heat storage bodies are located at the upper and lower ends of the internal centers of the first, second, and third heat storage chambers, and an adjustment device is located at the center of each of the three adjustment devices. A protective heat insulation device is located at the center of each of the three adjustment devices.

[0006] The adjustment device on one side includes two slides, which are respectively located at the center of the two inner walls of the first heat storage chamber. A first reciprocating rod is rotatably mounted on the center of the inner wall of each slide via a bearing. A connecting rod is provided at the lower end of each of the two first reciprocating rods, and a second reciprocating rod is provided at the lower end of each of the two connecting rods. A rotary motor is provided on both sides of the center of the lower end face of the first heat storage chamber. A moving block is threadedly connected to the upper end of the outer center of each of the two slides and the lower end of the outer center of each of the two second reciprocating rods.

[0007] Through the above technical solution, the output end of the rotary motor is fixedly connected between the first heat storage chamber and the second reciprocating rod, which enables the second reciprocating rod to rotate. The connecting rod then enables the first reciprocating rod to rotate. The transmission effect of the moving block enables the height adjustment of the ceramic heat storage body. This allows the height and position of the ceramic heat storage body to be adjusted in real time according to changes in the flow rate and composition of the exhaust gas, thereby optimizing heat exchange efficiency, extending the residence time of the exhaust gas in the heat storage chamber, and ensuring the full oxidation and decomposition of organic matter.

[0008] Furthermore, the end faces of the two upper movable blocks are respectively fixedly connected to the upper ceramic heat storage body, and the end faces of the two lower movable blocks are respectively fixedly connected to the lower ceramic heat storage body.

[0009] Through the above technical solution, the connection between the moving block and the ceramic heat storage body is made to meet the transmission requirements of the moving block to the ceramic heat storage body, thereby realizing the height adjustment of the ceramic heat storage body.

[0010] Furthermore, the two first reciprocating rods are symmetrically arranged between the two second reciprocating rods, respectively;

[0011] The above technical solution, through the symmetrical arrangement between the first reciprocating rod and the second reciprocating rod, enables the two ceramic heat storage bodies to move in opposite directions, thereby achieving height adjustment of the two ceramic heat storage bodies.

[0012] Furthermore, both of the aforementioned rotary motors are synchronously controlled;

[0013] Through the above technical solution, the encoder feedback signals of the two rotary motors are sent to the control system. By comparing the working states of the two rotary motors, the control signal of one of the rotary motors is adjusted to keep the two rotary motors synchronized, thereby achieving synchronous control. This solution is a commonly used technical method in the prior art, and will not be elaborated on here. Thus, synchronous control of the second reciprocating rod is achieved.

[0014] Furthermore, the protective heat insulation device on one side includes two heat insulation sleeves, which are respectively disposed on the inner walls of two sliding grooves. The two heat insulation sleeves are respectively sleeved and connected to the two first reciprocating rods and the two second reciprocating rods, and there is a gap between them. A sliding groove is provided at the center of the end face between the two heat insulation sleeves, and the two sliding grooves are slidably connected to the two moving blocks respectively.

[0015] Through the above technical solution, the heat insulation sleeve is sleeved and connected to the first and second reciprocating rods, which reduces heat conduction and prevents the first and second reciprocating rods from overheating and affecting normal operation, thereby improving the heat insulation and protection effect. Furthermore, the gap between the heat insulation sleeve and the first and second reciprocating rods allows for the normal operation of the first and second reciprocating rods. Finally, the sliding connection between the sliding groove and the moving block meets the normal movement requirements of the moving block.

[0016] Furthermore, a heat insulation pad is provided at the center of the lower end face of the first heat storage chamber, the second heat storage chamber and the third heat storage chamber, and a heat insulation shell is fitted at the center of the outer side of the two rotary motors;

[0017] The above technical solution uses heat insulation pads to block heat transfer between the bottom of the first, second, and third heat storage chambers and the external environment, reducing heat loss and preventing high temperatures from affecting the bottom components of the equipment. Furthermore, the heat insulation shell effectively blocks high-temperature heat radiation and heat conduction from the heat storage chambers and burners, reducing heat transfer to the rotating motor and protecting the internal coils, bearings, and other sensitive components of the rotating motor, ensuring its stable operation in high-temperature environments.

[0018] Furthermore, both first reciprocating rods and both second reciprocating rods are made of ceramic composite material;

[0019] The above technical solution enables the first and second reciprocating rods, made of ceramic composite materials, to have excellent high-temperature stability, maintain their mechanical strength and structural integrity in high-temperature environments, and meet the performance requirements of the first and second reciprocating rods in high-temperature and high-wear environments.

[0020] Furthermore, the exhaust gas delivery pipe, the cleaning pipe, and the purified air delivery pipe are respectively connected to the first heat storage chamber, the second heat storage chamber, and the third heat storage chamber via switching valves;

[0021] The above technical solution enables the interconnection of the exhaust gas delivery pipe, the cleaning pipe, and the purified air delivery pipe with the first, second, and third heat storage chambers via a switching valve, allowing for flexible control of the flow of exhaust gas, cleaning gas, and purified air between the heat storage chambers.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the three-tower RTO environmentally friendly heat storage waste gas treatment equipment is used, the output end of the rotary motor is fixedly connected between the first heat storage chamber and the second reciprocating rod, so that it can drive the second reciprocating rod to rotate. Then, through the connection of the connecting rod, it can meet the rotation requirements of the first reciprocating rod. Then, through the transmission effect of the moving block, it can meet the height adjustment requirements of the ceramic heat storage body. This allows the height and position of the ceramic heat storage body to be adjusted in real time according to the changes in waste gas flow and composition, thereby optimizing heat exchange efficiency, extending the residence time of waste gas in the heat storage chamber, and ensuring the full oxidation and decomposition of organic matter.

[0024] 2. In this utility model, the heat insulation sleeve is sleeved to the first and second reciprocating rods, reducing heat conduction and preventing overheating of the first and second reciprocating rods from affecting normal operation. Furthermore, the heat insulation pad blocks heat transfer between the bottoms of the first, second, and third heat storage chambers and the external environment, reducing heat loss and preventing high temperatures from affecting the bottom components of the equipment. The heat insulation shell protects the rotating motor, ensuring stable operation in high-temperature environments. Finally, the ceramic composite material used in the first and second reciprocating rods provides excellent high-temperature stability, maintaining mechanical strength and structural integrity in high-temperature environments, thus meeting the performance requirements of the first and second reciprocating rods under high-temperature and high-wear conditions, thereby improving the heat insulation and protection effect of the regulating device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4 This utility model provides an embodiment of a three-tower RTO (Regenerative Thermal Oxidizer) environmentally friendly heat storage waste gas treatment device, comprising a body 1 and a burner 5. The burner 5 is located at the upper center of the rear end face of the body 1. A first heat storage chamber 2 is located at one side of the center of the lower end face of the body 1, a second heat storage chamber 3 is located at the center of the lower end face of the body 1, and a third heat storage chamber 4 is located at the other side of the center of the lower end face of the body 1. A high-pressure blower 6 is located at one side of the lower end of the third heat storage chamber 4, and a waste gas conveying pipe 7 is located at the output end of the high-pressure blower 6. A cleaning pipe 8 is located at the rear center of the lower end of the second heat storage chamber 3, and a cleaning pipe 8 is located at the center of the lower end of the second heat storage chamber 3. There is a purified air delivery pipe 9, and an air outlet pipe 10 is provided at the output end of the purified air delivery pipe 9. Ceramic heat storage bodies 11 are provided at the upper and lower ends of the internal center of the first heat storage chamber 2, the second heat storage chamber 3 and the third heat storage chamber 4, and an adjustment device 12 is provided at the internal center of each of them. A protective heat insulation device 13 is provided at the internal center of each of the three adjustment devices 12. Through the adjustment device 12, the height and position of the ceramic heat storage body 11 can be adjusted in real time according to the changes in the flow rate and composition of the exhaust gas, thereby optimizing the heat exchange efficiency, extending the residence time of the exhaust gas in the heat storage chamber, and ensuring that the organic matter is fully oxidized and decomposed.

[0033] The side-mounted heat insulation device 13 includes two heat insulation sleeves 1301, which are respectively disposed on the inner walls of two sliding grooves 1201. The two heat insulation sleeves 1301 are respectively sleeved and connected to two first reciprocating rods 1202 and two second reciprocating rods 1204, with gaps between them. A sliding groove 1302 is provided at the center of the end face between the two heat insulation sleeves 1301, and the two sliding grooves 1302 are slidably connected to two moving blocks 1206. The heat insulation sleeves 1301 are connected to the first reciprocating rods 1202 and the second reciprocating rods 1206. The connection between the 04 rods is sleeved, which reduces heat conduction and prevents overheating of the first reciprocating rod 1202 and the second reciprocating rod 1204 from affecting normal operation, thereby improving the heat insulation effect. Furthermore, the gap between the heat insulation sleeve 1301 and the first reciprocating rod 1202 and the second reciprocating rod 1204 allows the normal operation of the first reciprocating rod 1202 and the second reciprocating rod 1204. Finally, the sliding groove 1302 is slidably connected to the moving block 1206, which meets the normal movement requirements of the moving block 1206.

[0034] A heat insulation pad 1304 is provided at the center of the lower end face of the first heat storage chamber 2, the second heat storage chamber 3, and the third heat storage chamber 4. A heat insulation shell 1303 is fitted around the center of the outer side of the two rotating motors 1205. The heat insulation pad 1304 blocks the heat transfer between the bottom of the first heat storage chamber 2, the second heat storage chamber 3, and the third heat storage chamber 4 and the external environment, reducing heat loss and preventing the impact of high temperature on the bottom components of the equipment. The heat insulation shell 1303 can effectively block the high temperature heat radiation and heat conduction from the heat storage chamber and the burner 5, reducing the heat transfer to the rotating motor 1205, and protecting the internal coils, bearings, and other sensitive components of the rotating motor 1205, ensuring its stable operation in high temperature environment.

[0035] The two first reciprocating rods 1202 and the two second reciprocating rods 1204 are both made of ceramic composite material. The ceramic composite material of the first reciprocating rods 1202 and the second reciprocating rods 1204 gives them excellent high-temperature stability, enabling them to maintain their mechanical strength and structural integrity in high-temperature environments, thus meeting the performance requirements of the first reciprocating rods 1202 and the second reciprocating rods 1204 in high-temperature and high-wear environments.

[0036] The exhaust gas delivery pipe 7, the cleaning pipe 8, and the purified air delivery pipe 9 are respectively connected to the first heat storage chamber 2, the second heat storage chamber 3, and the third heat storage chamber 4 through switching valves. The switching valves enable the connection between the exhaust gas delivery pipe 7, the cleaning pipe 8, and the purified air delivery pipe 9 and the first heat storage chamber 2, the second heat storage chamber 3, and the third heat storage chamber 4, allowing for flexible control of the flow of exhaust gas, cleaning gas, and purified air between the heat storage chambers.

[0037] like Figure 2 ,4 As shown, the adjustment device 12 on one side includes two slides 1201, which are respectively located at the center of the inner walls of the first heat storage chamber 2. A first reciprocating rod 1202 is rotatably mounted on the center of the inner wall of each slide 1201 via a bearing. A connecting rod 1203 is located at the lower end of each of the first reciprocating rods 1202, and a second reciprocating rod 1204 is located at the lower end of each of the connecting rods 1203. A rotary motor 1205 is located on both sides near the center of the lower end face of the first heat storage chamber 2. Moving blocks 120 are threadedly connected to the upper ends of the outer centers of the two slides 1201 and the lower ends of the outer centers of the two second reciprocating rods 1204. 6. The output end of the rotary motor 1205 is fixedly connected between the first heat storage chamber 2 and the second reciprocating rod 1204, so that it can drive the second reciprocating rod 1204 to rotate. Then, through the connection of the connecting rod 1203, it can meet the rotation requirements of the first reciprocating rod 1202. Then, through the transmission effect of the moving block 1206, it can meet the height adjustment requirements of the ceramic heat storage body 11. This allows the height and position of the ceramic heat storage body 11 to be adjusted in real time according to the changes in the flow rate and composition of the exhaust gas, thereby optimizing the heat exchange efficiency, extending the residence time of the exhaust gas in the heat storage chamber, and ensuring the full oxidation and decomposition of organic matter.

[0038] The end faces of the two upper movable blocks 1206 are fixedly connected to the upper ceramic heat storage body 11, and the end faces of the two lower movable blocks 1206 are fixedly connected to the lower ceramic heat storage body 11. Through the connection between the movable blocks 1206 and the ceramic heat storage body 11, the transmission requirements of the movable blocks 1206 to the ceramic heat storage body 11 are met, and the height adjustment of the ceramic heat storage body 11 is realized.

[0039] Two first reciprocating rods 1202 are symmetrically arranged with two second reciprocating rods 1204 respectively. The symmetrical arrangement of the first reciprocating rods 1202 and the second reciprocating rods 1204 enables them to drive the two ceramic heat storage bodies 11 to move in opposite directions, thereby realizing the height adjustment of the two ceramic heat storage bodies 11.

[0040] Both rotary motors 1205 are synchronously controlled. The encoder feedback signals of the two rotary motors 1205 are sent to the control system. By comparing the working states of the two rotary motors 1205, the control signal of one of the rotary motors 1205 is adjusted to keep the two rotary motors 1205 synchronized, thereby achieving synchronous control. This scheme is a commonly used technical means in the prior art, and will not be elaborated on here. This achieves synchronous control of the second reciprocating rod 1204.

[0041] Working principle: When using the three-tower RTO environmental protection thermal storage waste gas treatment equipment, the equipment also includes a control box, which includes sensors. The control box is responsible for receiving instructions, sending control signals, and monitoring the status of each component. The sensors are used to detect parameters such as position, temperature, and pressure of each component and feed this information back to the main controller. The actuators are responsible for performing specific operations. This is a commonly used technical means in existing control systems, and will not be elaborated on here.

[0042] According to a preset program or control logic, the switching valve periodically switches the connection path to ensure that each heat storage chamber goes through the stages of heat storage, oxidation decomposition and cleaning in sequence. This enables the exhaust gas delivery pipe 7, cleaning pipe 8 and purified air delivery pipe 9 to be connected to the first heat storage chamber 2, the second heat storage chamber 3 and the third heat storage chamber 4. This allows for flexible control of the flow of exhaust gas, cleaning gas and purified air between the heat storage chambers.

[0043] Exhaust gas is introduced into the equipment via a high-pressure blower 6 and an exhaust gas delivery pipe 7. The output end of a rotary motor 1205 is fixedly connected between the first heat storage chamber 2 and the second reciprocating rod 1204, enabling the second reciprocating rod 1204 to rotate. A connecting rod 1203 then connects the first reciprocating rod 1202, allowing it to rotate. The transmission effect of the moving block 1206 enables the height adjustment of the ceramic heat storage element 11, allowing for real-time adjustment based on changes in exhaust gas flow and composition. The height and position of the rod 1204 are optimized to improve heat exchange efficiency and extend the residence time of exhaust gas in the heat storage chamber, ensuring that organic matter is fully oxidized and decomposed. The encoder feedback signals of the two rotary motors 1205 are then sent to the control system. By comparing the working states of the two rotary motors 1205, the control signal of one of the rotary motors 1205 is adjusted to keep the two rotary motors 1205 synchronized, thereby achieving synchronous control. This scheme is a commonly used technical means in the prior art and will not be elaborated on here. This achieves synchronous control of the second reciprocating rod 1204.

[0044] By using a sleeve connection between the heat insulation sleeve 1301 and the first reciprocating rod 1202 and the second reciprocating rod 1204, heat conduction is reduced, preventing overheating of the first reciprocating rod 1202 and the second reciprocating rod 1204 from affecting normal operation. Furthermore, the heat insulation pad 1304 blocks heat transfer between the bottom of the first heat storage chamber 2, the second heat storage chamber 3, and the third heat storage chamber 4 and the external environment, reducing heat loss and preventing high temperatures from affecting the bottom components of the equipment. The heat insulation shell 1303 protects the rotary motor 1205, ensuring its stable operation in high-temperature environments. The ceramic composite material used in the first reciprocating rod 1202 and the second reciprocating rod 1204 provides excellent high-temperature stability, maintaining their mechanical strength and structural integrity in high-temperature environments. This satisfies the performance requirements of the first reciprocating rod 1202 and the second reciprocating rod 1204 under high-temperature and high-wear conditions, thereby improving the heat insulation and protection effect of the regulating device 12.

[0045] The preheated exhaust gas enters the area where the burner 5 is located, and undergoes an oxidation reaction with oxygen at high temperature to produce harmless substances such as carbon dioxide and water. After leaving the burner 5, the high-temperature purified gas enters another heat storage chamber, where it transfers heat to the ceramic heat storage body 11. The ceramic heat storage body 11 stores heat, and the temperature of the purified gas decreases. It is then transported to the exhaust pipe 10 through the purified air delivery pipe 9 for discharge. Clean air is then introduced through the cleaning pipe 8 to clean the heat storage chamber, removing residual organic matter and possible pollutants.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
