In the utility model, the gas in the interlayer of the chemical equipment material storage tank is treated and discharged regularly by the gas processing mechanism. When periodic maintenance or failure occurs, the gas processing mechanism is temporarily cut off, and the chemical gas is guided to the trapping and processing mechanism. The heavier materials entrained in the chemical gas are deposited in the interior of the phthalic anhydride trapping box, and the lighter materials and nitrogen enter the interior of the water seal tank for treatment and qualified discharge. The collected materials are periodically recycled to the phthalic anhydride tank for recycling. The water seal water is discharged to the sewage treatment system, solving the safety and environmental protection problems caused by gas emptying during environmental protection facility failure or device periodic maintenance.
