Problems solved by technology
These studies have achieved satisfactory results, but they are all on a small scale, all of which are batch reactors, lack of continuous type, and the treatment time is long, so large-scale industrial waste gas treatment cannot be carried out.

Embodiment 1
[0032] First, pressurize the high-concentration industrial waste gas 1 containing PCBs, NH3 and CO, water vapor and oxidizing agent through the first compressor 10, wherein the oxidizing agent is O 3 , O 3 The molar mass is 4 times of the molar mass of the oxidant required for the complete oxidation of the industrial waste gas 1, the water vapor is the supercritical carrier, and the volume of the water vapor at the inlet of the first compressor 10 accounts for 40% of the total volume of the mixed gas. Pressurize the industrial waste gas 1, ozone and water vapor to 5MPa through the first compressor 10;
[0033] Discharge the mixed gas compressed by the first compressor 10 into the heater 20, keep the first valve 11 and the second valve 21 closed, and continue to heat up to 600°C to form a high-pressure gas with a pressure of 15 MPa;
[0034]By delaying opening the second valve 21, the high-pressure gas in the heater 20 is discharged into the second compressor 30 for further pr...

The invention discloses a continuous exhaust gas treatment device, comprising an oxidant storage device, a steam generator, a first compressor, a heater, a second compressor, a serpentine reaction tube and a by-product recoverer, and an oxidant inlet on the first compressor and the water vapor inlet are respectively connected with the outlet of the oxidant storage and the outlet of the steam generator, the outlet of the first compressor is connected with the inlet of the heater, the outlet of the heater is connected with the inlet of the second compressor, and the outlet of the second compressor is connected with the inlet of the second compressor. The outlet of the compressor communicates with the inlet of the serpentine reaction tube, and the outlet of the serpentine reaction tube communicates with the inlet of the by-product recovery device; the outlet of the first compressor communicates with the inlet of the heater through a first valve. Correspondingly, the invention also discloses a continuous waste gas treatment method, which can quickly process high-concentration industrial waste gas.
Description
technical field [0001] The invention belongs to the field of industrial waste gas treatment, and relates to a continuous waste gas treatment device and method. Background technique [0002] Industrial waste gas includes various pollutant gases discharged into the air generated during fuel combustion and production processes in the factory area of the enterprise. The waste gas comes from chemical plants, pharmaceutical factories, printing and dyeing factories and other industries. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), volatile benzene and aromatics, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere . These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger hu...
