The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Example

[0035] like Figures 1-6As shown, this utility model provides a technical solution: the purification chamber 1, as the core housing component of the entire waste gas purification device, is made of high-strength corrosion-resistant materials, such as stainless steel or carbon steel with special anti-corrosion treatment. Its internal space is reasonably designed, providing a stable working environment for the subsequent waste gas purification process. It can effectively isolate harmful gases in the purification process, prevent them from leaking into the surrounding environment, and ensure the safety of operators and the surrounding environment. The shape and size of the chamber can be customized according to the actual application scenario and the amount of waste gas to be treated, so as to meet different engineering needs.

[0036] The intake pipe 21 in the intake assembly is the inlet channel for exhaust gas to enter the purification device. The intake pipe 21 is made of a material with good wear resistance and corrosion resistance, such as high-density polyethylene (HDPE) or a steel pipe lined with ceramic. The intake groove 22 opened inside the intake pipe 21 is the flow channel for exhaust gas. Its size is precisely calculated and designed according to the flow rate and velocity requirements of the exhaust gas to ensure that the exhaust gas can smoothly enter the purification chamber 1. The connecting groove 23 is opened on the outside of the intake groove 22. The outer and inner walls of the connecting groove 23 are provided with first connecting threads 24. This is to make a tight connection with the filter assembly. The threaded connection has the characteristics of firm connection and good sealing, which can effectively prevent exhaust gas from leaking at the connection.

[0037] The function of the intake pipe 21 is to introduce external exhaust gas into the purification device, the intake slot 22 provides a flow path for the exhaust gas, and the connecting slot 23 and its thread design are to achieve a reliable connection with the filter components, ensure the integrity and sealing of the entire intake system, and enable the exhaust gas to enter the subsequent treatment stage according to the predetermined path.

[0038] The installation pipe 31 in the filter assembly is also made of a corrosion-resistant and high-strength material, such as polypropylene (PP). The second connecting threads 32 on the outer and inner walls of the installation pipe 31 match the first connecting threads 24 of the intake assembly connection groove 23, enabling a convenient connection between the two. The installation balancing frame 33, located inside the installation pipe 31, plays a crucial supporting and positioning role. The installation balancing frame 33 is made of a lightweight but high-strength material, such as aluminum alloy or carbon fiber composite material. Because the second connecting threads 32 on the inner side of the installation pipe 31 need to match the two first connecting threads 24 of the connection groove 23… The connecting threads 24 are connected and fixed together, resulting in the air passage space in the installation pipe 31 having a shape that is larger on the outside and smaller on the inside. When the filter element 34 is installed, it will be blocked by the inner wall of the air inlet pipe 21. The installation balancing frame 33 is aligned with the inner wall of the air inlet pipe 21, so that the filter element 34 can completely fit the air inlet groove 22, thereby achieving the effect of complete filtration of exhaust gas. The filter element 34 selects a suitable filter material according to the composition and properties of the exhaust gas. For example, for exhaust gas containing dust and particulate matter, a high-efficiency fiber filter material can be selected; for exhaust gas containing harmful gas molecules, an activated carbon fiber filter material with adsorption function can be selected, etc.

[0039] The installation pipe 31 of the filter assembly is tightly connected to the air intake assembly through a threaded connection to ensure that the exhaust gas can smoothly enter the filtration area. The installation and balancing frame 33 solves the problem of irregular airflow space caused by the connection structure, so that the filter element 34 can be correctly installed and achieve the best filtration effect. The filter element 34, through its own filter material characteristics, intercepts, adsorbs or filters harmful substances in the exhaust gas, thus purifying the exhaust gas.

[0040] Since the second connecting thread 32 on the inner side of the installation pipe 31 needs to be connected and fixed with the two first connecting threads 24 of the connecting groove 23, the air passage space in the installation pipe 31 will be partially occupied by the inner wall of the air inlet pipe 21, resulting in the air passage space in the installation pipe 31 being larger on the outside and smaller on the inside. Therefore, when installing the filter element 34, it will be blocked by the inside of the air inlet pipe 21. Therefore, it is necessary to add a mounting balancing frame 33 to balance with the inner wall of the air inlet pipe 21, so that the filter element 34 can completely fit the air inlet groove 22 and achieve a complete filtration effect.

[0041] The gas transmission pipe 41 serves as the connection between the filter assembly and the external pipeline. The gas transmission groove 42 inside the pipe is the channel for gas transmission. The size and shape of the gas transmission groove 42 are designed according to the gas flow and pressure requirements to ensure efficient gas transmission. The connecting flange 43 installed on the outside of the gas transmission groove 42 is made of standard specification metal materials, such as carbon steel or stainless steel. The connecting flange 43 is connected to the external pipeline by bolts and other connectors. This connection method has the advantages of strong connection, easy disassembly and installation. At the same time, the gas transmission pipe 41 is fixed by the threaded connection between the gas transmission groove 42 and the second connecting thread 32 of the installation pipe 31, ensuring the sealing and stability of the gas transmission process.

[0042] The gas transmission tank 42 is responsible for the transmission of gas, and the connecting flange 43 is used to establish a connection with the external pipeline, so that the exhaust gas can smoothly enter the filter assembly for treatment from the external pipeline. The threaded connection with the installation pipe 31 ensures that the gas will not leak during the transmission process and maintains the stable operation of the entire gas transmission system.

[0043] The air quality monitor 5 employs advanced sensor technologies, such as electrochemical sensors and infrared sensors, to monitor the gas purified by the purification chamber 1 in real time. It can accurately detect the concentration of various pollutants in the gas, such as sulfur dioxide, nitrogen oxides, and particulate matter. Based on preset gas quality standards, when the purified gas quality is found to be substandard, the air quality monitor 5 will issue a signal to remind the user to replace the filter components. The display screen of the air quality monitor 5 can intuitively display the detected gas parameters and has data storage and transmission functions, facilitating long-term tracking and analysis of the purification effect by operators.

[0044] The exhaust port 6 is located at the top of the purification chamber 1. Its design takes into account the smoothness and safety of gas discharge. The size of the exhaust port 6 is calculated according to the processing capacity of the purification device to ensure that the purified gas can be discharged into the atmosphere in a timely and efficient manner. A protective net is usually installed at the exhaust port 6 to prevent foreign objects from entering the purification chamber 1. At the same time, it performs preliminary diffusion of the discharged gas to reduce the risk of excessively high local gas concentration.

[0045] The purified gas is safely and smoothly discharged into the outside atmosphere through exhaust port 6. The protective net ensures the cleanliness and normal operation of the purification chamber 1 and prevents foreign objects from entering and affecting the purification effect.

[0046] Work process summary

[0047] Exhaust gas introduction: External exhaust gas is transmitted to the filter assembly through the external pipe connected to the gas transmission assembly via the gas transmission groove 42 of the gas transmission pipe 41. The gas transmission pipe 41 is connected to the external pipe through the connecting flange 43 to ensure a firm connection and good sealing. At the same time, the gas is accurately introduced into the filter assembly through the threaded connection with the installation pipe 31.

[0048] Filtration process: After the exhaust gas enters the installation pipe 31, it is filtered by the filter element 34. Due to the function of the installation balancing frame 33, the filter element 34 can completely fit the air inlet slot 22, effectively filtering the harmful substances in the exhaust gas. The installation pipe 31 is connected to the air inlet component connecting slot 23 by a thread, which ensures a tight fit between the filter component and the air inlet component, so that the exhaust gas can only enter the air inlet slot 22 through the filter element 34, and then enter the purification chamber 1.

[0049] Purification treatment: After the filtered waste gas enters the purification chamber 1, it undergoes further purification treatment inside the purification chamber 1. The specific purification methods may include various technologies such as chemical adsorption and catalytic reaction, depending on the specific composition of the waste gas and the purification requirements.

[0050] Emission monitoring: After purification, the gas is discharged through exhaust port 6. During this process, air quality detector 5 monitors the purified gas in real time. If the gas quality meets the standards, the exhaust gas is discharged normally. If the gas quality does not meet the standards, air quality detector 5 will send a signal to remind the user to replace the filter components to ensure the subsequent purification effect.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
