Waste gas treatment system capable of interchanging combustion analytical gas and fuel gas of nightlight

Abstract

The invention discloses a waste gas treatment system capable of interchanging combustion analytical gas and fuel gas of a nightlight. The waste gas treatment system comprises a pressure swing adsorption device for separating waste gases, a gas tank for storing analytical gas and a switching device for interchanging the combustion analytical gas and the fuel gas; a pressure sensor under a weighbridge is electrically connected to a control computer; the switching device comprises a switching pipe, a connecting pipe for connecting other pipelines, a rotating shaft, a switching plate and a servo motor; and a large gear fixedly connected to the end, extending out of the switching pipe, of the rotating shaft is meshed with a pinion fixedly connected to the servo motor. According to the waste gastreatment system capable of interchanging combustion analytical gas and fuel gas of the nightlight, the servo motor drives the switching plate and a blanking plate to rotate towards any side to blockone of a gas outlet pipe or a fuel gas pipe, and the other one of the gas outlet pipe and the fuel gas pipe communicates with the nightlight by a pipeline, so that the combustion analytical gas and the fuel gas are flexibly switched, the analytical gas is sufficiently utilized, and not only is the use amount of the fuel gas reduced, but also environment pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment equipment in methanol workshops, in particular to an exhaust gas treatment system capable of exchanging burning analyte gas and fuel gas for an ever-burning lamp. Background technique [0002] The released gas produced in the production of the methanol workshop passes through the pressure swing adsorption device, and a part of the hydrogen gas with a purity of 99.9% is analyzed as the raw material hydrogen for hydrogenation, and a part of it produces a large amount of waste gas (analysis gas), which contains a large amount of CH 4 The combustible gas is sent to the torch for direct combustion through the vent pipeline. Therefore, while bringing pollution to the environment, it causes a great waste of resources. In addition, the long-burning lamp of the heating furnace is in a long-term burning state, which requires a large amount of CH 4 Other combustible gases, CH 4 Combustible g...
