Abstract
Description
Technical Field
[0001] This invention relates to the field of organic waste gas treatment technology, and in particular to a high-efficiency organic waste gas catalytic combustion device. Background Technology
[0002] Organic waste gas mainly originates from the waste gas emitted during the production process of the petroleum and chemical industries. It is characterized by large quantities, large fluctuations in organic matter content, flammability, certain toxicity, and some even have a foul odor. Furthermore, the emission of chlorofluorocarbons can also cause ozone layer depletion. Moreover, the organic waste gas generated in these production processes is characterized by its high difficulty in treatment.
[0003] Catalytic combustion equipment utilizes a catalyst to achieve complete oxidation of organic matter at low temperatures (200–400°C). Therefore, it consumes little energy, is easy and safe to operate, and boasts high purification efficiency, making it suitable for purifying organic waste gases, especially those with limited recovery value. However, existing catalytic combustion equipment still has certain drawbacks, including: because the catalyst is a single unit, the limited contact area between the waste gas and the catalyst restricts the catalytic combustion efficiency of the organic waste gas and may lead to insufficient contact, thus affecting the purification effect of the waste gas treatment. Summary of the Invention
[0004] This invention discloses a high-efficiency catalytic combustion device for organic waste gas, which aims to solve the technical problem that when the catalyst is set as a whole, the contact area between the waste gas and the catalyst is limited, thus restricting the catalytic combustion efficiency of organic waste gas and potentially causing insufficient contact, thereby affecting the purification effect of waste gas treatment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-efficiency catalytic combustion device for organic waste gas includes a preheating mechanism, a heating mechanism, and a catalytic combustion mechanism. The preheating mechanism and the heating mechanism are located on one side of the catalytic combustion mechanism. The catalytic combustion mechanism includes a supporting shell. A three-way pipe is provided on the inner wall of one side of the supporting shell. The three-way pipe includes one inlet and two outlets. The inlet of the three-way pipe is connected to the preheating mechanism, and the two outlets of the three-way pipe are respectively connected to a third vent pipe. One end of the third vent pipe is connected to a second connecting pipe, and a guide fan is provided on the inner wall of the second connecting pipe. The guide fan is located on the supporting shell. A porous filter element is provided in the inlet of the three-way pipe, and a second porous filter element is provided in the other two outlets of the three-way pipe. A catalytic reaction tank is connected to the inner wall of one side of the third vent pipe. The catalytic reaction tank is arranged in a repeatedly bent state. A catalyst is attached to the inner wall of the catalytic reaction tank. A heating bed plate is provided on the inner wall of one side of the supporting shell, and multiple electric heating tubes are provided in the heating bed plate. A heat-conducting plate is connected between the third vent pipe and the heating bed plate.
[0007] Equipped with a catalytic combustion mechanism, the organic waste gas, after initial filtration, is preheated by a preheating mechanism and then enters the supporting shell through a three-way pipe. The waste gas is then split through the three-way pipe, and stabilized by a porous filter element, ensuring uniform splitting. The split waste gas undergoes secondary stabilization through a second porous filter element, allowing it to stably enter the second connecting pipe. After entering the second connecting pipe, the waste gas, under the action of a guide fan, enters the catalytic reaction tank and repeatedly impacts the catalyst on the bent inner wall of the catalytic reaction tank, undergoing a full reaction on the catalyst surface. This accelerates the catalytic combustion efficiency of the organic waste gas, making it more efficient and further ensuring the purification level of the treated organic waste gas.
[0008] In a preferred embodiment, the supporting shell has an internal cavity located at the bottom of the heating bed plate. The catalytic reaction tank includes a fourth exhaust port connected to the cavity. An exhaust pipe is provided on the inner wall of the heating bed plate, with its bottom end located within the cavity. The top end of the exhaust pipe is snapped into the top of the supporting shell. The preheating mechanism includes a sleeve with an air inlet at its top and an exhaust port at its bottom. The air inlet is connected to a gas supply pipe, one end of which is also connected to the exhaust pipe. A vent pipe is connected to the inner wall of the sleeve, and an annular cavity is formed between the sleeve and the vent pipe. The vent pipe is located on the outer wall inside the sleeve. A heat storage layer is provided, and a second heat storage layer is also provided on the inner wall of one side of the vent pipe of the sleeve. The second heat storage layer is located at the center of the vent pipe. The heat storage layer includes a copper sleeve, and the inner wall of the copper sleeve is attached to the outer wall of the vent pipe. The copper sleeve is filled with ceramic fragments. The second heat storage layer includes a second vent pipe, and the second vent pipe is located inside the vent pipe. The top end of the second vent pipe is provided with a second air inlet, and the bottom end of the second vent pipe is provided with a second exhaust outlet. The second air inlet and the second exhaust outlet are located in an annular cavity. A filter screen is provided inside the second vent pipe, and the filter screen is filled with second ceramic fragments. A temperature monitoring instrument is also provided inside the vent pipe.
[0009] By incorporating a preheating mechanism, the hot gas generated after waste gas treatment in the catalytic combustion mechanism passes through a cavity, and the heat in the hot gas is received and stored by ceramic fragments and a second ceramic fragment. This fully utilizes the hot gas generated by the catalytic combustion mechanism for secondary utilization. Simultaneously, since the second heat storage layer is located at the center of the vent pipe, when the waste gas passes through the vent pipe, it passes through the gap between the second heat storage layer and the vent pipe. Under the action of the second heat storage layer and the heat storage layer, the preheating contact area of the waste gas is increased, thereby improving the preheating efficiency of the waste gas. At the same time, the ceramic fragments and the second ceramic fragment are used for heat storage, and the ceramic waste is utilized, reducing the production cost of the device.
[0010] In a preferred embodiment, the heating mechanism includes a water storage tank, a connecting pipe is provided on one inner wall of the water storage tank and the connecting pipe is connected to an exhaust port, a third exhaust port is provided on the top inner wall of the water storage tank, and multiple nozzles are provided on one inner wall of the water storage tank and the multiple nozzles are arranged in a cavity.
[0011] By incorporating a heating mechanism, when the exhaust gas volume is insufficient or the exhaust gas treatment is discontinuous, a long interval can lead to a drop in temperature within the preheating mechanism, preventing it from reaching the appropriate temperature. Adding a heater to the preheating mechanism would increase energy consumption and costs. In this invention, when the temperature monitor detects insufficient temperature within the preheating mechanism, water from the storage tank is sprayed out through a nozzle, allowing the water to contact the lower surface of the heating bed plate, generating high-temperature water vapor. This vapor then enters the preheating mechanism through the air supply pipe, ensuring the temperature within the preheating mechanism. This process cools the cavity that has been heated for a long time while simultaneously utilizing existing heat energy to power the preheating mechanism, thus saving costs. Furthermore, by collecting the gas discharged from the exhaust port, when the gas enters the storage tank, its temperature drops, causing water to separate and be collected, enabling the secondary use of wastewater. This also ensures a dry working environment, preventing water accumulation on the ground and avoiding inconvenience.
[0012] As described above, a high-efficiency organic waste gas catalytic combustion device includes a preheating mechanism, a heating mechanism, and a catalytic combustion mechanism. The preheating mechanism and the heating mechanism are located on one side of the catalytic combustion mechanism. The catalytic combustion mechanism includes a supporting shell. A three-way pipe is provided on the inner wall of one side of the supporting shell. The three-way pipe includes one inlet and two outlets. The inlet of the three-way pipe is connected to the preheating mechanism, and the two outlets of the three-way pipe are respectively connected to a third vent pipe. One end of the third vent pipe is connected to a second connecting pipe, and a guide fan is provided on the inner wall of the second connecting pipe. The guide fan is located on the supporting shell. A porous filter element is provided in the inlet of the three-way pipe, and a second porous filter element is provided in the other two outlets of the three-way pipe. A catalytic reaction tank is connected to the inner wall of one side of the third vent pipe, and the catalytic reaction tank is arranged in a repeatedly bent state.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] The high-efficiency catalytic combustion device for organic waste gas disclosed in this invention is mainly applied to the treatment of organic waste gas.
[0022] Reference Figure 1 , Figure 2 and Figure 6A high-efficiency catalytic combustion device for organic waste gas includes a preheating mechanism 1, a heating mechanism 2, and a catalytic combustion mechanism 3. The preheating mechanism 1 and the heating mechanism 2 are located on one side of the catalytic combustion mechanism 3. The catalytic combustion mechanism 3 includes a supporting shell 304. A three-way pipe 312 is provided on the inner wall of one side of the supporting shell 304. The three-way pipe 312 includes one inlet and two outlets. The inlet of the three-way pipe 312 is connected to the preheating mechanism 1, and the two outlets of the three-way pipe 312 are respectively connected to a third vent pipe 309. One end of the vent pipe 309 is connected to a second connecting pipe 314, and a guide fan 310 is installed on the inner wall of the second connecting pipe 314. The guide fan 310 is mounted on the supporting housing 304. A porous filter element 311 is installed in the inlet of the three-way pipe 312, and a second porous filter element 313 is installed in each of the other two outlets of the three-way pipe 312. A catalytic reaction tank 305 is connected to one side of the inner wall of the third vent pipe 309, and the catalytic reaction tank 305 is arranged in a repeatedly bent state. The inner wall of the catalytic reaction tank 305 is fitted with a catalyst. The agent 308 is used. A heating bed plate 303 is provided on one inner wall of the supporting shell 304, and multiple electric heating tubes 302 are provided in the heating bed plate 303. A heat-conducting plate 315 connects the third vent pipe 309 and the heating bed plate 303. After the organic waste gas is initially filtered, it is preheated by the preheating mechanism 1, and then enters the supporting shell 304 through the three-way pipe 312. The waste gas is split through the three-way pipe 312. Under the action of the porous filter element 311, the waste gas is stabilized and it can be evenly split. The separated waste gas undergoes secondary stabilization through the second porous filter element 313, allowing it to stably enter the second connecting pipe 314. After entering the second connecting pipe 314, the waste gas, under the action of the guide fan 310, enters the catalytic reaction tank 305 and repeatedly impacts the catalyst 308 on the bent inner wall of the catalytic reaction tank 305, where it undergoes a full reaction on the surface of the catalyst 308. This accelerates the catalytic combustion efficiency of the organic waste gas, making it more efficient and further ensuring the purification level of the organic waste gas treatment.
[0023] Reference Figure 2 and Figure 6 In a preferred embodiment, the support shell 304 has a cavity 301 inside, and the cavity 301 is located at the bottom end of the heating bed plate 303. The catalytic reaction tank 305 includes a fourth exhaust port 307, and the fourth exhaust port 307 is connected to the cavity 301. The inner wall of the heating bed plate 303 is provided with an exhaust pipe 306, and the bottom end of the exhaust pipe 306 is located in the cavity 301. The top end of the exhaust pipe 306 is engaged with the top of the support shell 304.
[0024] Reference Figure 2 and Figure 3In a preferred embodiment, the preheating mechanism 1 includes a sleeve 102, with an air inlet 105 at the top end and an exhaust port 104 at the bottom end. The air inlet 105 is connected to an air supply pipe 101, and one end of the air supply pipe 101 is connected to an exhaust pipe 306. A vent pipe 103 is connected to the inner wall of the sleeve 102, and an annular cavity is provided between the sleeve 102 and the vent pipe 103.
[0025] Reference Figure 2 and Figure 3 In a preferred embodiment, a heat storage layer 108 is provided on the outer wall of the vent pipe 103 located inside the sleeve 102, and a second heat storage layer 106 is provided on the inner wall of the vent pipe 103 located on one side of the sleeve 102. The second heat storage layer 106 is located at the center of the vent pipe 103.
[0026] Reference Figure 3 and Figure 4 In a preferred embodiment, the heat storage layer 108 includes a copper sleeve 1081, and the inner wall of the copper sleeve 1081 is attached to the outer wall of the vent pipe 103. The copper sleeve 1081 is filled with ceramic fragments 1082.
[0027] Reference Figure 5 In a preferred embodiment, the second heat storage layer 106 includes a second vent pipe 1062, which is located inside the vent pipe 103. The top end of the second vent pipe 1062 is provided with a second air inlet 1061, and the bottom end of the second vent pipe 1062 is provided with a second exhaust outlet 1065. The second air inlet 1061 and the second exhaust outlet 1065 are located inside the annular cavity.
[0028] Reference Figure 5 In a preferred embodiment, a filter sleeve 1063 is provided inside the second vent pipe 1062, and the filter sleeve 1063 is filled with second ceramic fragments 1064. A temperature monitor 107 is also provided inside the vent pipe 103. The hot gas generated in the catalytic combustion mechanism 3 after exhaust gas treatment passes through the cavity 301 and enters the sleeve 102 along the exhaust pipe 306 and the air supply pipe 101. Part of the hot gas passes through the annular cavity and is discharged from the exhaust port 104, while the other part passes through the second heat storage layer 106 and is discharged from the second exhaust port 104. The exhaust gas is discharged at 65°C. At the same time, the heat of the hot gas is received and stored by the ceramic fragment 1082 and the second ceramic fragment 1064, making full use of the hot gas generated by the catalytic combustion mechanism 3 to achieve secondary utilization. Meanwhile, since the second heat storage layer 106 is located at the center of the vent pipe 103, when the exhaust gas passes through the vent pipe 103, the exhaust gas passes through the gap between the second heat storage layer 106 and the vent pipe 103. Under the action of the second heat storage layer 106 and the heat storage layer 108, the preheating contact area of the exhaust gas is increased, thereby improving the preheating efficiency of the exhaust gas.
[0029] Reference Figure 2 In a preferred embodiment, the heating mechanism 2 includes a water storage tank 202. A connecting pipe 201 is provided on one inner wall of the water storage tank 202, and the connecting pipe 201 is connected to the exhaust port 104. A third exhaust port 203 is provided on the top inner wall of the water storage tank 202. Multiple nozzles 204 are provided on one inner wall of the water storage tank 202, and the multiple nozzles 204 are arranged in the cavity 301. When the exhaust gas volume is insufficient and the exhaust gas treatment is discontinuous, the long interval will cause the temperature in the preheating mechanism 1 to drop and fail to reach the suitable temperature. If a heater is added to the preheating mechanism 1, it will lead to increased energy consumption and increased cost. In this invention, when the temperature monitoring instrument 107 detects that the temperature in the preheating mechanism 1 is insufficient, Water from the water storage tank 202 is sprayed out through the nozzle 204, causing the water to come into contact with the lower surface of the heating bed plate 303, generating high-temperature water vapor. This vapor then enters the preheating mechanism 1 through the air supply pipe 101, where it is stored in the heat storage layer 108 and the second heat storage layer 106 to maintain the temperature inside the preheating mechanism 1. This process cools the cavity 301, which has been heated for a long time, and also uses existing heat energy to power the preheating mechanism 1, thus saving costs. At the same time, the gas discharged from the exhaust port 104 is collected. When the gas enters the water storage tank 202, its temperature drops, and water is separated and collected, enabling the secondary use of wastewater. This also ensures a dry working environment and prevents water from accumulating on the ground and causing inconvenience.
[0030] Working principle: During use, after the organic waste gas undergoes preliminary filtration, it is preheated by the preheating mechanism 1, and then enters the supporting shell 304 through the three-way pipe 312. The waste gas is then split through the three-way pipe 312, and stabilized by the porous filter element 311, allowing it to be evenly split. The split waste gas undergoes secondary stabilization through the second porous filter element 313, ensuring that the waste gas can stably enter the second connecting pipe 314. After entering the second connecting pipe 314, the waste gas is guided into the catalytic reaction tank 305 by the fan 310, and repeatedly impacts the bends in the catalytic reaction tank 305. On the catalyst 308 on the wall, a full reaction takes place on the surface of the catalyst 308, thereby accelerating the catalytic combustion efficiency of the organic waste gas, making it more efficient, and further ensuring the purification level of the organic waste gas treatment. Then, the hot gas generated in the catalytic combustion mechanism 3 after the waste gas treatment passes through the cavity 301 and enters the sleeve 102 along the exhaust pipe 306 and the air supply pipe 101. Part of the hot gas passes through the annular cavity and is discharged from the exhaust port 104, and another part passes through the second heat storage layer 106 and is discharged from the second exhaust port 1065. At the same time, the heat of the hot gas is absorbed by the ceramic fragments 1082 and 1064. The heat is collected and stored, making full use of the heat generated by the catalytic combustion mechanism 3 for secondary utilization. Simultaneously, since the second heat storage layer 106 is located at the center of the vent pipe 103, when exhaust gas passes through the vent pipe 103, it passes through the gap between the second heat storage layer 106 and the vent pipe 103. Under the action of the second heat storage layer 106 and the heat storage layer 108, the preheating contact area of the exhaust gas is increased, thereby improving the preheating efficiency. When the exhaust gas volume is insufficient and the temperature monitoring instrument 107 detects that the temperature inside the preheating mechanism 1 is insufficient, water from the water storage tank 202 is sprayed out through the nozzle 204, allowing the water to contact the heating bed plate 30. High-temperature water vapor is generated on the lower surface of 3 and enters the preheating mechanism 1 through the air supply pipe 101. It is stored in the heat storage layer 108 and the second heat storage layer 106 to ensure the temperature inside the preheating mechanism 1. While cooling the cavity 301 that has been heated for a long time, it also uses the existing heat energy to power the preheating mechanism 1, which saves costs. At the same time, the gas discharged from the exhaust port 104 is collected. When the gas enters the water storage tank 202, the temperature drops and water is separated and collected, realizing the secondary use of wastewater. It also ensures that the working environment is dry and avoids water accumulation on the ground, which would cause inconvenience.
