The utility model relates to a synthetic chemical test purification table, belonging to the technical field of chemical test devices. The synthetic chemical test purification table is characterized in that an operation table is arranged on a purification test table, a pit is formed in the operation table, and a heater is arranged on the operation table; a rotary column is arranged close to the inner end of the operation table; a cleaning chamber is arranged below the operation table; a purification top plate is arranged above the operation table, fine holes are formed in the purification top plate, and a purification device is arranged in the purification top plate; a spraying pipe, a smoke alarm and a camera are arranged close to the outer side of the purification top plate; a water supply tank is arranged at the upper part of the purification top plate. The synthetic chemical test purification table is convenient for carrying out multiple test operations, has a monitoring function, and can be used for monitoring a smoke condition due to the arrangement of the smoke alarm. According to the synthetic chemical test purification table, chemical liquid waste generated in a chemical process is discharged into a liquid waste chamber after being neutralized and diluted, so that security incidents are reduced. The synthetic chemical test purification table is convenient to use, has multiple functions and is suitable for being popularized and used in chemical tests.

The utility model discloses a chemical waste gas processing system, and relates to a purification device. Waste gas and waste liquid produced in the work of chemical equipment are collected through a waste liquid and waste gas collection box, and then the waste gas and the waste water are treated through an air outlet and a water outlet, respectively. By adopting the chemical waste gas processing system, the waste liquid and waste gas released in the chemical production can be simultaneously processed, and the air quality can be effectively improved.
