[0014] Beneficial effects

[0015] This invention provides a device for purifying and treating exhaust gas after detection. Compared with the prior art, it has the following advantages:

[0016] 1. This exhaust gas detection and purification device allows exhaust gas to enter the first purification chamber through the inlet pipe under the action of an exhaust fan. First, it undergoes preliminary filtration through a filter plate to remove large particulate impurities. Then, the motor starts, driving a reciprocating screw to rotate. A movable slider, threadedly connected to the reciprocating screw, moves linearly back and forth along the screw under the constraint of a limit rod. This drives a cleaning brush to clean the surface of the filter plate, effectively preventing the filter plate from losing filtration efficiency due to impurities and ensuring long-term stable operation of the device. Simultaneously, the motor rotation also drives the drive wheel to rotate, which in turn drives the driven wheel via a belt, causing one of the spray pipes to rotate. Because the gears on the two spray pipes mesh, they rotate synchronously in opposite directions, allowing the atomizing nozzles on the spray pipes to spray and purify the exhaust gas from all directions, compensating for the purification dead zones that might exist when the nozzles are fixed in position.

[0017] 2. This exhaust gas detection and purification device takes the exhaust gas after its initial purification in the first purification chamber and introduces it into the second purification chamber through a connecting pipe. There, it undergoes further adsorption and purification via an activated carbon filter. The exhaust gas detector in the second purification chamber monitors the exhaust gas indicators in real time. When the exhaust gas fails to meet standards, a solenoid reversing valve controls a three-way pipe to reintroduce the exhaust gas into the first purification chamber for secondary purification until it meets the standards before being discharged. Through the cooperation of the exhaust gas detector and the solenoid reversing valve, automatic circulation and purification of substandard exhaust gas is achieved, ensuring that the final discharged exhaust gas meets environmental standards.

The filter plate 21 can perform preliminary filtration of the exhaust gas and intercept and filter out particulate impurities in the exhaust gas.

[0029] Both spray pipes 210 are rotatably installed on the inner wall of the first purification chamber 1. A set of atomizing nozzles is provided on one side of the outer wall of each of the two spray pipes 210. One end of the outer wall of each of the two spray pipes 210 penetrates one side of the outer wall of the first purification chamber 1 and is fixedly connected to a rotary joint 212. A driven wheel 29 is fixedly installed on the outer wall of one of the two spray pipes 210. A solution that can absorb waste gas can be introduced into the spray pipe 210 through the rotary joint 212. The rotary joint 212 is existing technology and can provide liquid to the spray pipe 210 when it is rotating.

[0030] Figures 1-4The second embodiment is shown. The main difference from the first embodiment is that: one end of the outer wall of the reciprocating screw 22 penetrates the outer wall of the first purification chamber 1 and is fixedly installed with a drive wheel 27. The outer walls of the drive wheel 27 and the driven wheel 29 are fitted with belts 28. A motor 23 is fixedly installed on the outer wall of the first purification chamber 1. The output shaft of the motor 23 penetrates the inner wall of the first purification chamber 1 and is fixedly connected to the other end of the outer wall of the reciprocating screw 22. When the reciprocating screw 22 rotates, it can drive the drive wheel 27 to rotate. The drive wheel 27 drives the driven wheel 29 and a spray pipe 210 to rotate through the belt 28.

[0031] The outer wall of the first purification chamber 1 is fixedly connected to a connecting pipe 3. The output end of the connecting pipe 3 is fixedly connected to the second purification chamber 41. The second purification chamber 41 is fixedly connected to the first purification chamber 1. The outer wall of the three-way pipe 43 is provided with an electromagnetic reversing valve 44.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the exhaust gas, driven by the exhaust fan 6, enters the first purification chamber 1 through the intake pipe 5. First, it undergoes preliminary filtration through the filter plate 21 to remove large particulate impurities. At this time, the motor 23 starts, driving the reciprocating screw 22 to rotate. The movable slider 25, threadedly connected to the reciprocating screw 22, moves linearly back and forth along the screw 22 under the constraint of the limit rod 24. This drives the cleaning brush 26 to clean the surface of the filter plate 21, effectively preventing the filter plate 21 from reducing filtration efficiency due to impurities and ensuring long-term stable operation of the device. Simultaneously, the rotation of motor 23 also drives the drive wheel 27 to rotate, which in turn drives the driven wheel 29 to rotate via belt 28, thereby driving one of the spray pipes 210 to rotate. Since the gears 211 on the two spray pipes 210 mesh with each other, the two spray pipes 210 will rotate synchronously in opposite directions, so that the atomizing nozzles on the spray pipes 210 spray and purify the exhaust gas from all directions, making up for the purification dead zone problem that may exist when the nozzle position is fixed. After the exhaust gas is initially purified by the first purification chamber 1, it enters the second purification chamber 41 through the connecting pipe 3, and is further adsorbed and purified by the activated carbon filter plate 42. The exhaust gas detector 45 in the second purification chamber 41 monitors the exhaust gas indicators in real time. When the exhaust gas is detected to be substandard, the three-way pipe 43 is controlled by the electromagnetic reversing valve 44 to introduce the exhaust gas back into the first purification chamber 1 for secondary purification until the exhaust gas meets the standards and is discharged. Through the cooperation of the exhaust gas detector 45 and the electromagnetic reversing valve 44, the substandard exhaust gas is automatically circulated and purified, ensuring that the final discharged exhaust gas meets environmental protection standards.
