Abstract
The invention provides a tail gas micro-discharge circulation system and a tail gas purification treatment method of a waste plastic oilation device, and aims at solving the problems that in an existing waste rubber, plastic and waste oil regeneration recycling process, the waste gas treatment does not meet the standard, and waste gas which does not meet the standard is easily discharged. The tail gas is filtered and absorbed by multiple systems such as a gas-water separator, a pipeline filter, a combined type drying machine, a filtering device, an absorption tower, a dust filter and the like; the purified tail gas is monitored by an on-line monitoring device in an on-line way; if being detected to be qualified, the tail gas is stored and then discharged; if being detected to be unqualified, the tail gas returns back and is treated in a circulating way until the tail gas meet the standard.
