Title:
NOVEL WASTE GAS TREATMENT APPARATUS BASED ON 485 COMMUNICATION TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2017/147806
Kind Code:
A1
Abstract:
A novel waste gas treatment apparatus based on 485 communication technology, comprising: a central control room (1) and a waste gas treatment mechanism electrically connected to the central control room (1). The waste gas treatment mechanism comprises an inlet tube (2), a waste gas collecting mechanism of an air conducting unit (4) communicating with the inlet tube (2), a waste gas treatment unit comprising a waste gas plasma treatment device (5), and a waste gas emission mechanism. The waste gas collecting mechanism communicates, via the waste gas treatment unit, with the waste gas emission mechanism. The inlet tube (2) is internally provided with an axial flow fan (16). The air conducting unit (4) is internally provided with an airflow dividing pipe (3). A communication circuit of the waste gas treatment apparatus uses a bidirectional diode (VD1) to absorb an inverse peak voltage, and uses a first optical coupler (N1) and a second optical coupler (N2) for isolation. The waste gas treatment apparatus is efficient in waste gas treatment and has high communication reliability.
