Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device with an automatic medicine adding mechanism. Background Art

[0002] During the production process, factories will generate a large amount of harmful waste gas. These waste gases cannot be discharged directly into the air and need to be collected for waste gas treatment. The treated gas can only be discharged into the air after it meets the gas emission standards. The method of waste gas treatment is usually to pass the waste gas into the treatment liquid. The harmful substances in the waste gas will react with the pharmaceutical solution in the treatment liquid to neutralize the waste gas so that the waste gas meets the emission standards.

[0003] When treating waste gas, there is a situation where the chemical reaction between the waste gas and the treatment liquid is insufficient, resulting in the treated gas failing to meet the emission standards. The amount of reagents needs to be increased to meet the waste gas treatment requirements. Therefore, it is necessary to manually add reagents. When adding reagents, the device needs to be opened, which can easily cause waste gas leakage. Not only is the operation very troublesome, but it is also inconvenient to control the amount of reagents added. Therefore, improvement is urgently needed. Utility Model Content

[0032] When the embodiment of the present application is in use: first, the exhaust gas treatment device is mainly composed of three parts: an exhaust gas treatment tank 1, a gas detection tank 4, and a medicine storage tank 10. The exhaust gas is introduced into the dispersion plate 6 on the top of the exhaust gas treatment tank 1 through the air inlet pipe 5. The dispersion plate 6 guides the exhaust gas into the dispersion pipe 20. The exhaust gas is evenly discharged through the exhaust hole 21 and fully contacts with the treatment liquid inside the exhaust gas treatment tank 1. The harmful substances in the exhaust gas react with the pharmaceutical solution in the treatment liquid to make the exhaust gas meet the emission standards. When the exhaust gas is introduced, the cross opening 23 inside the rubber membrane 22 is opened. When the exhaust gas is not introduced, the cross opening 23 is closed, thereby preventing the treatment liquid from pouring into the dispersion pipe 2. 0, then, the treated gas enters the gas detection tank 4 through the air guide pipe 26, and the gas detector 25 detects the gas. When the gas does not meet the emission standard, the circulating air pump 27 extracts the gas inside the gas detection tank 4 and re-introduces it into the intake pipe 5, so that the gas enters the exhaust gas treatment tank 1 again for further treatment until it meets the emission standard. The solenoid valve inside the exhaust pipe 24 is opened to discharge the gas, thereby ensuring the eligibility of the exhaust gas emission. When it is necessary to add medicine, the telescopic drive member 15 is controlled by operating the external controller to drive the piston 9 to move upward. At this time, the solenoid valve inside the medicine taking tube 16 is opened, and the medicine is taken. The tube 16 draws the medicine inside the medicine storage tank 10 into the medicine adding cylinder 8, and the amount of the medicine drawn can be measured according to the scale line on the surface of the medicine adding cylinder 8, so as to control the amount of medicine added. Then, the electromagnetic valve inside the medicine taking tube 16 is closed, and the electromagnetic valve inside the medicine adding tube 13 is opened, and then the telescopic driving member 15 is controlled to drive the piston 9 to move downward, and the piston 9 presses the medicine inside the medicine adding cylinder 8 out, so that the medicine is discharged into the exhaust gas treatment tank 1 through the medicine adding tube 13, and the rotating driving member 7 drives the stirring rod 2 to rotate, and the stirring rod 2 drives the stirring blade 3 to rotate to stir the medicine evenly, thereby realizing the automatic dosing function, which is easy to operate, will not cause leakage of exhaust gas, and is easy to control. The amount of medicine added, and the medicine inside the medicine storage tank 10 is a transparent liquid, the laser transmitter 12 emits a laser beam, and the laser receiver 19 receives the laser beam. The position of the laser beam and the medicine taking tube 16 are staggered, and the two do not interfere with each other. As the medicine inside the medicine storage tank 10 decreases, the floating block 18 inside the hollow tube 17 drops as the liquid level drops. When the floating block 18 drops to the inside of the hollow tube 17, it blocks the laser beam emitted by the laser transmitter 12. The laser receiver 19 cannot receive the laser beam emitted by the laser transmitter 12, then the alarm is triggered to sound an alarm to remind the staff to replenish the medicine, thereby automatically reminding when the medicine is insufficient.
