Embodiment Construction
[0028] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0029] refer to figure 1 As shown, the present invention provides a low-cost, high-efficiency desulfurization and denitrification method for desulfurization and denitrification of flue gas, comprising the following steps:
[0030] S1. Collect exhaust gas; the exhaust gas can be exhaust gas from steel mills or steelmaking, or exhaust gas containing sulfur dioxide and nitrogen monoxide from other chemical plants.
[0031] S2. Pass the steam into the nozzle of the ejector, pass the waste gas into the suction chamber of the ejector, and simultaneously pass oxygen and ozone into the suction chamber;
[0032] S3, passing the mixed gas into the thermod...

The invention discloses a low-cost and high-efficiency desulfurization and denitrification method and system for flue gas desulfurization and denitrification, comprising the following steps: S1, collecting exhaust gas; S2, passing steam into the jet nozzle, and the suction chamber of the jet into The exhaust gas is simultaneously fed into the suction chamber with oxygen and ozone; S3, passing the mixed gas into the thermoelectric motor to provide power for the thermodynamic motor; S4, condensing the mixed gas, and collecting the condensed nitric acid and sulfuric acid; S5, the Exhaust the remaining gas. The present invention can conveniently chemically react nitrogen monoxide and sulfur dioxide in the waste gas of the steel plant into sulfuric acid or nitric acid, reduce the nitrogen and sulfur in the waste gas, and can use the preheating in the steam at the same time to improve the energy utilization rate and reduce the Equipment quantity and cost.
Description
technical field [0001] The invention relates to the technical field of heat recovery, and more specifically relates to a low-cost and high-efficiency desulfurization and denitrification method and system.
