Title:
WASTE GAS DISCHARGE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/095371
Kind Code:
A1
Abstract:
Disclosed is a waste gas discharge apparatus comprising a filter compartment (1), an adsorption plate inside the filter compartment, a gas receiving compartment (2) on a side of the filter compartment, and a controller (4), wherein the filter compartment is divided into an acid-base chamber (1.1), a water washing chamber (1.2) and an adsorption chamber (1.3), the adsorption plate is provided in an inclined manner in the adsorption chamber, an upper end of the adsorption chamber is provided with a channel passing into the gas receiving compartment, the gas receiving compartment is divided by a partition plate into a detection chamber (2.1) and a release chamber (2.2), the middle of the partition plate is provided with a gas detector (5), the bottom of the partition plate is provided with a one-way valve (6) from the detection chamber to the release chamber, the bottom of the detection chamber is provided with a return pipe (7) passing into the filter compartment, the return pipe is provided with a return flow one-way valve (7.1) from the detection chamber to the filter compartment, the gas detector is connected to the controller, and the controller is connected to and controls the one-way valve and the return flow one-way valve. By means of the gas detector detecting harmful substances in the waste gas, a signal is emitted to the controlled when the detection meets the standard, such that the controller controls the one-way valve to open, waste gas enters the release chamber and then is discharged into the atmosphere, and when the detection does not meet the standard, the controller controls the return flow one-way valve to open, waste gas flows into the filter compartment and is then filtered again, such that waste gas is filtered and purified. The structure is simple, and waste gas emissions are made to achieve the standards.
