Novel light organic matter stripping tower for treating wastewater generated during production of acrylonitrile

The utility model belongs to the field of production of acrylonitrile, and particularly relates to a novel light organic matter stripping tower for treating wastewater generated during production of acrylonitrile. The novel light organic matter stripping tower comprises a tower body (1); 30 layers of tower plates are arranged in the tower body (1) from bottom to top; a liquid collection groove (18) is formed between a tower plate No.1 and an air ascending pipe; a side line extraction balance port (4), a side line extraction port (5) and a side line extraction liquid return port (6) are formed at the lower section of the tower body (1), wherein the side line extraction balance port (4), and the side line extraction port (5) are connected with the top of a light organic matter stripping tower buffer tank (11) through pipelines; the bottom of the light organic matter stripping tower buffer tank (11) is connected with a water inlet end of a light organic matter stripping tower discharge pump (13); and the bottom of the tower body (1) is provided with a kettle liquid outlet (8) and a kettle liquid reboiler port (9). The novel light organic matter stripping tower has a scientific and reasonable structure, the amount of the recycled wastewater which is treated by the organic matter stripping tower can be improved by about 3 to 5 times, the using amount of heated vapor of the light organic matter stripping tower can be reduced by about 40 to 50 percent, and economic benefit is greatly improved.
