[0014] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0015] Please refer to Figure 1The utility model provides a technical scheme: a kind of condensation and adsorption and RTO furnace integrated waste gas treatment device, including oil-gas loading and unloading area 10, oil-gas storage tank area 11, combustion chamber 1 and chimney 2, oil-gas loading and unloading area 10 and oil-gas storage tank area 11 are communicated respectively by oil-gas communication pipe and two groups of oil-gas recovery system 8, two groups of oil-gas recovery system 8 are double-channel oil-gas cooling structure, condensing unit is provided in oil-gas recovery system 8, two groups of oil-gas recovery system 8 are communicated with explosion-proof induced draft fan 6, first regenerator 5, second regenerator 3 and third regenerator 4 respectively by oil-gas communication pipe, and first regenerator 5, second regenerator 3 and third regenerator 4 are all arranged at the bottom of combustion chamber 1, combustion chamber 1 is communicated with combustion air fan 14, and the top of combustion chamber 1 is provided with explosion vent 13, combustion chamber 1, first regenerator 5, second regenerator 3 and third regenerator 4 are all communicated by oil-gas communication pipe and chimney 2, air communication port, pressure sensor, three sets of emergency discharge port 12 and four groups of fire arrester 9 are provided on oil-gas communication pipe, by double-channel oil-gas cooling structure, the device can be stably operated, simultaneously by setting condensing unit, material in waste gas is separated quickly, by setting combustion chamber 1, it can guarantee that waste gas can reach the set oxidation temperature, simultaneously guarantee that there is sufficient residence time and makes VOC in waste gas fully oxidize, thus purified waste gas enters cooling tower and lye washing tower to remove sulfur compound again, can be discharged into atmosphere by chimney 2, so that the waste gas with complex composition can be conveniently and quickly purified.
