Description

Technical Field

[0001] This utility model relates to an organic waste gas emission reduction device, belonging to the technical field of organic waste gas treatment equipment. Background Technology

[0002] Organic waste gases generated in industrial production environments are usually at high temperatures. When these organic waste gases are discharged, they need to undergo adsorption treatment to meet emission standards or further reduce the organic content of the emitted waste gases. Activated carbon is usually used for adsorption in the adsorption layer. However, due to the high temperature of the waste gases, the adsorption performance of activated carbon is limited. In other words, the activated carbon layer cannot fully perform its adsorption function, which may result in the organic content of the emitted waste gases remaining at a high level. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an organic waste gas emission reduction device, which is used to cool the high-temperature waste gas before adsorbing organic matter in the adsorption layer, thereby improving the adsorption capacity of the adsorption layer for organic matter, which is conducive to further reducing the content of organic matter in the air so as to meet the emission standards.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides an organic waste gas emission reduction device, including a ventilation pipe. The ventilation pipe has at least two installation ports arranged vertically to communicate with the inner cavity of the ventilation pipe. An adsorption layer covering the cross-section of the ventilation pipe is installed in the topmost installation port. Cooling devices are installed in the remaining installation ports to cool the organic waste gas in the ventilation pipe.

[0006] Specifically, the ventilation duct includes an air inlet duct, an air outlet duct, and a connecting duct for connecting the air inlet duct and the air outlet duct. Multiple installation ports are provided on the connecting duct, and each installation port penetrates both sides of the connecting duct body.

[0007] Specifically, the cooling device includes multiple finned tubes installed inside the ventilation duct through an installation port, and a refrigeration source for introducing a low-temperature medium into the finned tubes.

[0008] Specifically, the low-temperature medium is a coolant, and the refrigeration source is a coolant circulation supply system for connecting the finned tubes.

[0009] Specifically, the cooling source consists of several fans located on one side of the installation port.

[0010] Specifically, it also includes a mounting plate with multiple mounting holes. Each finned tube is mounted on the corresponding mounting plate through the mounting holes. The mounting plate is installed inside the mounting port and is used to isolate the inner cavity of the ventilation duct from the external environment. The fan is installed on the outside of the mounting port and is used to direct the generated airflow from the mounting port on the other side through the finned tube.

[0011] Specifically, the mounting holes are arranged in an alternating array on the mounting plate, and the mounting hole positions on both sides of each mounting port correspond to each other.

[0012] Specifically, the fan is mounted on one side of the mounting port via a mounting base, and an air-collecting cavity is formed between the mounting base and the mounting plate. The air-collecting cavity is connected to the outside air only through the fan and the finned tube.

[0013] Specifically, the ventilation duct is located on the upper and lower sides of the adsorption layer and is connected to an air outlet detection port and an air inlet detection port, respectively.

[0014] Specifically, a pedestrian ladder is provided on one side of the ventilation duct.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] This invention cools the organic waste gas before it enters the adsorption layer, which significantly improves the adsorption capacity of the adsorption layer compared to adsorbing high-temperature gases. This helps reduce the organic content of the emitted waste gas, making it easier to meet emission standards or further reduce the organic content. In addition, by setting up an additional detection gas path, the adsorption capacity of the adsorption layer can be easily judged, thus providing guidance for personnel to replace the adsorption layer.

[0023] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0026] This utility model provides an organic waste gas emission reduction device, which is used to cool high-temperature waste gas before the adsorption layer adsorbs organic matter, thereby improving the adsorption capacity of the adsorption layer for organic matter, which is beneficial to further reduce the content of organic matter in the air so as to meet the emission standards. In order to realize the function of the device, the device is provided with a ventilation pipe. Specifically, there are not less than two installation ports 4 arranged vertically on the ventilation pipe for communicating with the inner cavity of the ventilation pipe. The top installation port 4 is equipped with an adsorption layer 7 covering the cross-section of the ventilation pipe, and the other installation ports 4 are equipped with cooling devices. The cooling devices are used to cool the organic matter in the ventilation pipe. The exhaust gas is cooled, and preferably, there are at least two installation ports 4 for installing the cooling device, with sufficient spacing between each pair of adjacent installation ports 4. This allows for stratified cooling of the gas. The specific cooling method can be thermal contact, where the internal gas comes into contact with the external cooling source through a medium to achieve the cooling process. Preferably, the cooling device includes multiple finned tubes 5 installed inside the ventilation duct through the installation ports 4, and a cooling source for introducing a low-temperature medium into the finned tubes 5. The inside of the finned tubes 5 provides a low-temperature environment, while the inside of the ventilation duct comes into contact with the outer wall of the finned tubes 5 to achieve heat exchange and thus the cooling process.

[0027] This utility model provides an organic waste gas emission reduction device. To facilitate pipeline installation, a ventilation duct is provided, including an inlet pipe 1, an outlet pipe 2, and a connecting pipe 3 for connecting the inlet pipe 1 and the outlet pipe 2. Multiple installation ports 4 are located on the connecting pipe 3. That is, the connecting pipe 3 is a non-standard pipe body, which can be processed and assembled separately, avoiding the overly complicated processing of other pipelines. To ensure smooth installation and ventilation, such as... Figure 1 and Figure 4 As shown, each installation port 4 extends through both sides of the connecting pipe 3 to facilitate manual operation from the outside.

[0028] This utility model provides an organic waste gas emission reduction device. As one method of low-temperature cooling gas, the low-temperature medium can be set as coolant, and the cooling source is a coolant circulation supply system for connecting the finned tubes 5. The coolant flows from inside the finned tubes 5, thereby achieving efficient cooling. However, since the finned tubes 5 usually need to be evenly distributed in an array inside the ventilation pipe, the installation steps of sealing each finned tube 5 and allowing the coolant to flow in an orderly manner inside it are too cumbersome. Therefore, as another cooling method, the cooling source can be set as several fans 8 set on one side of the installation port 4. The fans 8 can allow the ambient air to blow over each finned tube 5, so that each finned tube 5 can be cooled individually.

[0029] This utility model provides an organic waste gas emission reduction device. To facilitate the installation of the finned tubes 5, the device also includes a mounting plate 6. Specifically, the mounting plate 6 has multiple mounting holes, and each finned tube 5 is installed on the corresponding mounting plate 6 through the mounting holes. The mounting plate 6 is installed inside the mounting port 4 and is used to isolate the inner cavity of the ventilation pipe from the external environment, thus achieving a corresponding sealing effect. The fan 8 is installed on the outside of the mounting port 4 to direct the generated airflow through the finned tubes 5 from the other side of the mounting port 4. To ensure the uniform arrangement of the finned tubes 5, the mounting holes can be arranged in a staggered array on the mounting plate 6. The mounting hole positions on both sides of each mounting port 4 correspond to each other. This array can include not only horizontal arrays but also vertical arrays. The evenly distributed mounting holes can be arranged in a honeycomb pattern on the mounting plate 6 to ensure that the high-temperature organic waste gas can fully contact the surface of the finned tubes 5.

[0030] This utility model provides an organic waste gas emission reduction device. In order to ensure the supply efficiency of external ambient air, a fan 8 can be installed on one side of the mounting port 4 via a mounting base. An air collecting cavity is formed between the mounting base and the mounting plate 6. The air collecting cavity is connected to the outside air only through the fan 8 and the finned tube 5. That is, in this state, the wind pressure generated by the fan 8 in a fixed direction can only flow to the other side of the mounting port 4 through the finned tube 5, thereby effectively improving the utilization rate of the ambient air generated by the fan 8.

[0031] This utility model provides an organic waste gas emission reduction device. To facilitate the replacement of the adsorption layer 7, an exhaust detection port 11 and an inlet detection port 9 are respectively connected and installed on the upper and lower sides of the ventilation pipe located on the adsorption layer 7. The inlet detection port 9 is preferably located below the bottom mounting port 4 to accurately detect the organic content in the waste gas. When the exhaust detection port 11 detects an abnormal organic content in the emitted waste gas, the refrigeration system needs to be adjusted or the adsorption layer 7 needs to be replaced. For this purpose, the adsorption layer 7 can be easily slidably inserted and installed on the mounting port 4 of the ventilation pipe (it is necessary to ensure positioning and sealing). Depending on the actual use needs, it can be replaced approximately every two working days. To facilitate manual replacement, a pedestrian ladder 10 can be installed on one side of the ventilation pipe.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
