[0021] Example 1, such as Figures 1-4 As shown, a hazardous gas treatment device for producing tris(hydroxymethyl)aminomethane includes a pretreatment chamber 1, a neutralization chamber 2, and a detection chamber 3. An inlet pipe 4 with its other end extending into the pretreatment chamber 1 is fixedly installed on the left side. A particulate filter 5 is slidably installed inside the pretreatment chamber 1. A fan 6 is fixedly installed on the top of the pretreatment chamber 1. The right side of the fan 6 is connected to the interior of the pretreatment chamber 1 via a pipe. The right side of the fan 6 is connected to the left side of a gas guiding assembly 7. The gas guiding assembly 7 is fixedly installed inside the neutralization chamber 2. The left side of the neutralization chamber 2 is connected to the interior of the detection chamber 3 via a pipe. Waste gas sensors 8 are fixedly installed on the left and right sides of the inner wall of the detection chamber 3. An exhaust pipe 9 extending into the bottom of the detection chamber 3 is fixedly installed on the top of the detection chamber 3. A control panel 10 is fixedly installed on the right side of the detection chamber 3. A return pipe 11 extending into the pretreatment chamber 1 with its other end is fixedly installed on the rear side of the detection chamber 3. Both the exhaust pipe 9 and the return pipe 11 are controlled by valves. Both waste gas sensors 8 are electrically connected to the control panel 10, and the control panel 10 is electrically connected to the valves.

[0022] Harmful gases enter the pretreatment chamber 1 through the inlet pipe 4, pass through the particulate filter 5 to remove impurities, and are then transported to the gas guiding assembly 7 by the fan 6. The neutralization chamber 2 has an inlet pipe on the right side and a drain pipe at the bottom for adding a weak acid solution. The gas guiding assembly 7 transports the pretreated harmful gases to the weak acid solution for acid-base neutralization. The gas then rises and enters the detection chamber 3 through a pipe, where the exhaust gas sensor 8 performs two-stage harmful gas concentration detection. During inspections, the data can be observed via the control panel 10. If the emission standard is met, the valve at the exhaust pipe 9 opens to allow the gas to escape. If the emission standard is not met, the valve at the return pipe 11 opens, allowing the purification process to repeat.

[0023] Example 2, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows: the number of particulate filters 5 is two and they are symmetrically distributed inside the pretreatment box 1.

[0024] This enhances the effectiveness of pretreatment of harmful gases, thereby improving the efficiency of subsequent acid-base neutralization.

The left side of the air outlet pipe 703 extends into the interior of the air collecting pipe 702. There are several air outlet pipes 703, which are evenly distributed on the left side of the air collecting pipe 702. The air collecting pipe 702 is fixedly installed on the top of the support frame 704. The top of the support frame 704 has exhaust holes 705 with a number corresponding to the number of air outlet pipes 703. The support frame 704 is fixedly installed inside the neutralization box 2.

[0026] The pretreated gas enters the gas collecting pipe 702 through the connecting pipe 701, and then enters the multiple gas outlet pipes 703. It is then discharged downward through the exhaust port 705. Under the action of the support frame 704, the gas collecting pipe 702 and the gas outlet pipe 703 can be better supported.

[0027] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows: Three evenly distributed guide plates 12 are fixedly installed on the left and right sides of the inner wall of the detection box 3, and the guide plates 12 are placed at an angle.
