Beschreibung
Zusammenfassung:	The utility model discloses a coking industry low-oxygen VOCs deep treatment system which comprises a pressure balancer, the pressure balancer is composed of a first collecting pipe, a second collecting pipe, a third collecting pipe and a laser on-line oxygen content analyzer, the pressure balancer is connected with a control system, an output port of the pressure balancer is provided with a connecting main pipe, and the connecting main pipe is connected with the laser on-line oxygen content analyzer. And a stop valve and a flame arrester are arranged on the connecting main pipe. The low-oxygen gas volatile matter treatment device has the beneficial effects that low-oxygen gas volatile matters generated in a blast cooling tank area, a crude benzene area and a reservoir area are introduced into a coke oven gas negative pressure system by adopting a method of'centralized collection and negative pressure recovery ', and pressure balance is carried out through a pressure balance system before the low-oxygen gas v
