If the industrial waste gas is applied to the synthetic leather industry, most of the waste gas enters the system by three versions of process waste gas, firstly, the waste gas passes through a water washing device 1, and an emergency bypass pipeline is arranged at the device to lead to a chimney 15. After the DMF-containing waste gas is subjected to one water washing, most DMF is dissolved in water, a small part of undissolved DMF waste gas and other VOCs waste gas which is not easy to be water, such as toluene, continue to enter the two-channel water washing equipment 2, and DMF waste water is led to a waste water treatment process. The residual little DMF waste gas and other VOCs waste gas which is not easy to water are mixed with the hotter clean gas discharged from the regenerative oxidation furnace 6 after passing through the two-channel water washing device 2, pass through the multiple filtering device 3 and finally enter the concentration rotating wheel 4. The system selects proper concentration ratio according to specific working conditions of the process, and after the gas passes through the concentration rotating wheel 4, most of the gas reaching the standard is directly discharged to the chimney 15, and the other part of the gas enters the mixed flow heating box 5. The small amount of gas is sufficiently mixed with the high-temperature clean gas discharged from the thermal bypass of the regenerative oxidizing furnace 6 to become the desorption gas of the concentration wheel 4 having a proper temperature, and the gas passes through the desorption region of the concentration wheel 4. The concentrated exhaust gas is fed into a regenerative oxidation furnace 6 and subjected to a sufficiently high-temperature reaction. Subsequently, a portion of the clean gas is exhausted through a thermal bypass, which serves as two points: part of the gas is used for heating the hot water boiler 10 to generate hot water vapor for a production line, and the gas is mixed with clean gas discharged by the regenerative oxidation furnace 6 after passing through the hot water boiler 10 and enters the filtering equipment 3 together and returns to the concentration rotating wheel 4 again, so that the problem of high intermittent discharge concentration of the regenerative oxidation furnace 6 is solved, and meanwhile, redundant waste heat is fully utilized to generate economic benefit; the other path of clean hot air which is bypassed by the heat accumulating type oxidation furnace 6 passes through the mixed flow heating box 5 and is mixed with cooler gas which enters the concentration rotating wheel 4 through multiple filtration to become desorption gas of the concentration rotating wheel 4. And most of the clean gas after full reaction in the regenerative oxidation furnace 6 is introduced into the filtering equipment 3.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
