Description

Technical Field

[0001] This utility model relates to the technical field of process exhaust gas treatment, and in particular to a process exhaust gas treatment system. Background Technology

[0002] Process exhaust gas refers to the waste gas generated during industrial production processes. In various industrial activities, such as chemical synthesis, metal smelting, and thermal power generation, various gases are generated as raw materials are input and processed, and chemical reactions occur. In addition to common gases like nitrogen and oxygen, these gases also contain a large number of polluting components, such as particulate matter, sulfur dioxide, nitrogen oxides, carbon monoxide, and volatile organic compounds.

[0003] If these exhaust gases are released directly into the atmosphere without effective treatment, they will cause various environmental hazards, such as acid rain, photochemical smog, and exacerbation of the greenhouse effect. They will also threaten human health, causing respiratory and cardiovascular diseases and even cancer. Therefore, the effective treatment and control of process exhaust gases is a key link in sustainable industrial development and environmental protection, and is crucial for maintaining ecological balance and human health.

[0004] In current exhaust gas treatment processes, the reaction chamber is typically heated externally, which limits the heating effect. The heat generated after exhaust gas treatment is not utilized, and the exhaust gas usually enters the reaction chamber directly, which can easily lead to uneven distribution of the exhaust gas upon entering the reaction chamber. This can prevent the exhaust gas from fully contacting the reactants, and some reactants cannot participate in the reaction in time, thus reducing the reaction efficiency.

[0005] Currently, no effective solutions have been proposed to address the problems of limited heating effect and uneven reaction in related technologies. Utility Model Content

[0217] This embodiment is a modified embodiment of Embodiments 1 and 2.

[0218] like Figure 6As shown, the exhaust gas treatment device 100 also includes a dispersion unit 140. The dispersion unit 140 is disposed at the bottom of the interior of the treatment unit 110 and is connected to the treatment unit 110, and is used to disperse the process exhaust gas to be treated so that the process exhaust gas to be treated enters the treatment unit 110 evenly.

[0219] like Figure 7 As shown, the dispersion unit 140 includes a dispersion element 141 and a plurality of through-hole elements 142. The dispersion element 141 is disposed at the bottom end inside the processing unit 110 and communicates with the processing unit 110, and is used to disperse the process exhaust gas to be treated so that the process exhaust gas to be treated enters the processing unit 110 evenly; the plurality of through-hole elements 142 are distributed at the top end of the dispersion element 141, and are used to discharge the process exhaust gas to be treated.

[0233] The process exhaust gas generated by the machine is transported to the dispersion element 141 through the exhaust gas input element 112, and then enters the processing element 111 through the through hole element 142.

[0234] The advantage of this invention is that the dispersion unit allows the process exhaust gas to enter the treatment unit evenly, so that the process exhaust gas can fully contact the treatment material of the treatment unit. The uniform dispersion can ensure that the concentration of process exhaust gas in the treatment unit is uniform, avoiding local concentrations that are too high or too low.
