System for automatically purifying sulfide and nitrogen oxide in mixed gas

Abstract

The invention discloses a system for automatically purifying sulfide and nitrogen oxide in mixed gas. The system comprises detection equipment, control equipment, desulfurization equipment and denitrification equipment, wherein the detection equipment is provided with an air inlet hole and three vent holes; and one of another two vent holes of the detection equipment is connected with the desulfurization equipment through a pipeline, and the other vent hole is connected with the denitrification equipment through a pipeline. The system has the advantages that: the sulfur content and the nitrogen oxide content of flue gas can be detected automatically; the desulfurization equipment and the denitrification equipment are started according to the presence of the sulfide and the nitrogen oxide in the fuel gas, so that intermittent work of the desulfurization equipment and the denitrification equipment is realized, and the aim of saving energy is fulfilled; and running cost is low.

Description

technical field [0001] The invention relates to a system for removing sulfide and nitrogen oxides in mixed gas, in particular to a system for automatically purifying sulfide and nitrogen oxides in mixed gas. Background technique [0002] At present, in the treatment of flue gas containing sulfur and nitrogen oxides, the main methods used are dry or wet methods. Most desulfurization and denitrification equipment work in a continuous and non-intermittent manner, but in some special production processes, desulfurization and denitrification equipment are required to work intermittently, and if old-fashioned equipment is used, energy will be wasted. This requires a desulfurization and denitrification equipment that can automatically detect the sulfur content and nitrogen oxide content in the flue gas. According to whether the flue gas contains sulfide and nitrogen oxides, it is decided whether to start the desulfurization and denitrification equipment, so as to realize the inter...
