[0024] According to an embodiment of the present invention, a waste gas treatment device with protective function is provided, including a protective air inlet box 1, a waste gas protection component 2 is provided on one side of the protective air inlet box 1, a waste gas conveying component 3 is provided on one side of the waste gas protection component 2, and a waste gas pretreatment component 4 is provided on one side of the waste gas conveying component 3.

[0025] like Figure 1-4 As shown, according to an embodiment of the present invention, the exhaust gas treatment device with protective function includes an exhaust gas protection component 2, which includes an exhaust gas inlet pipe 201 connected to a protective inlet box 1. A filter mounting bracket 202 is installed inside the protective inlet box 1, and an impurity filter 203 is installed inside the filter mounting bracket 202. A heat exchanger tube 204 is installed inside the protective inlet box 1, and a liquid outlet pipe 205 is connected below the heat exchanger tube 204. The liquid outlet pipe 205 contains... There is a liquid outlet valve 206, and one end of the liquid outlet pipe 205 is connected to a liquid outlet nozzle 207. One side of the protective air inlet box 1 is connected to a liquid discharge pipe 208. The liquid discharge pipe 208 and the exhaust gas inlet pipe 201 are respectively equipped with shut-off valves 209. A PLC controller 5 is installed on one side of the protective air inlet box 1. The liquid outlet valve 206 and the shut-off valve 209 are electrically connected to an external power supply. One end of the heat exchange curved pipe 204 is connected to a condensate pump 8. The condensate pump 8 is electrically connected to the PLC controller 5.

[0026] Through the above technical solution, the exhaust gas enters the protective intake box 1 through the exhaust gas inlet pipe 201. The exhaust gas protection component 2 first activates its protective function: dust in the exhaust gas is intercepted by the impurity filter 203 fixed on the filter mounting bracket 202; simultaneously, a low-temperature condensing medium is introduced into the heat exchange curved pipe 204 installed inside the protective intake box 1 and driven by the condensate pump 8, causing the exhaust gas temperature to drop sharply, thus reducing the exhaust gas temperature. Periodically, the liquid outlet valve 206 and the shut-off valve 209 in the liquid discharge pipe 208 are activated, and the shut-off valve 209 in the exhaust gas inlet pipe 201 is closed. The liquid outlet nozzle 207 atomizes and sprays, causing the dust on one side of the impurity filter 203 to be flushed out, and finally the waste liquid is discharged through the liquid discharge pipe 208.

[0027] like Figure 1-4 As shown, the exhaust gas treatment device with protective function according to the embodiment of the present utility model includes an exhaust gas conveying component 3, which includes an exhaust gas suction pipe 301. One end of the exhaust gas suction pipe 301 is connected to an exhaust gas suction fan 302, and the output end of the exhaust gas suction fan 302 is connected to an exhaust pipe 303. The exhaust gas suction fan 302 is electrically connected to an external power source.

[0028] Through the above technical solution, the pre-treated waste gas is transferred by the waste gas conveying component 3: the waste gas suction fan 302 draws gas from the protective air inlet box 1 under negative pressure through the waste gas suction pipe 301, and after pressurization, it is conveyed to the waste gas pretreatment component 4 through the exhaust pipe 303. The start-up, shutdown and power of the waste gas suction fan 302 are uniformly controlled by the PLC controller 5 to ensure the stability of gas delivery.

[0029] like Figure 1-4 As shown, the exhaust gas treatment device with protective function according to the embodiment of the present utility model includes an exhaust gas pretreatment component 4, which includes a pretreatment box 401, a pretreatment mounting groove 402, a pretreatment mounting plate 403 that is slidably and sealed inside the pretreatment mounting groove 402, an activated carbon filter plate 404 that is installed inside the pretreatment mounting plate 403, a gas discharge pipe 6 that is connected to one side of the pretreatment box 401, and a replacement pull plate 7 that is connected above the pretreatment mounting plate 403.

[0030] Through the above technical solution, after the waste gas enters the waste gas pretreatment component 4, it undergoes deep adsorption in the pretreatment box 401: the gas passes through the pretreatment mounting plate 403, which is slidably and sealed within the pretreatment mounting groove 402, where the activated carbon filter plate 404 embedded inside adsorbs residual organic matter and odors. When the activated carbon is saturated, the entire pretreatment mounting plate 403 is slid out of the box along the pretreatment mounting groove 402 for replacement by manually lifting and replacing the replacement pull plate 7. Finally, the purified gas is transported to the external flare for final treatment through the gas discharge pipe 6.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, the exhaust gas enters the interior of the protective air intake box 1 through the exhaust gas inlet pipe 201. The exhaust gas protection component 2 first activates its protective function: the dust in the exhaust gas is intercepted by the impurity filter 203 fixed on the filter mounting bracket 202; at the same time, the heat exchange curved pipe 204 installed inside the protective air intake box 1 is circulated with a low-temperature condensing medium driven by the condensate pump 8, causing the exhaust gas temperature to drop sharply, thus reducing the temperature of the exhaust gas. The liquid outlet valve 206 and the shut-off valve 209 in the liquid discharge pipe 208 are periodically activated, and the shut-off valve 209 in the exhaust gas inlet pipe 201 is closed. The liquid outlet nozzle 207 atomizes and sprays the liquid, causing the dust on one side of the impurity filter 203 to be flushed out, and finally the waste liquid is discharged through the liquid discharge pipe 208.

[0033] The pre-treated exhaust gas is transferred by the exhaust gas conveying assembly 3: the exhaust gas suction fan 302 draws gas from the protective intake box 1 under negative pressure through the exhaust gas suction pipe 301, pressurizes it, and then conveys it to the exhaust gas pretreatment assembly 4 through the exhaust pipe 303. The start-up, shutdown, and power of the exhaust gas suction fan 302 are uniformly controlled by the PLC controller 5 to ensure the stability of gas delivery;

[0034] After the exhaust gas enters the exhaust gas pretreatment component 4, it undergoes deep adsorption within the pretreatment chamber 401: the gas passes through the pretreatment mounting plate 403, which is slidably and sealed within the pretreatment mounting groove 402, where the activated carbon filter plate 404 embedded inside adsorbs residual organic matter and odors. When the activated carbon is saturated, the entire pretreatment mounting plate 403 is slid out of the chamber along the pretreatment mounting groove 402 for replacement by manually lifting and replacing the replacement pull plate 7. Finally, the purified gas is transported to the external flare for final treatment via the gas discharge pipe 6.
