The company attaches great importance to environmental protection while vigorously improving the economic benefits of the enterprise and paying attention to product quality. The company leaders, in line with the principle of creating a good production and living environment for the employees and the surrounding residents, collect and deal with the waste gas generated in the operation process and completely eliminate the hidden dangers of the enterprise's development. Entrusted by the company, shandong baolan environmental protection engineering co., LTD. Based on the design principle of mature and reliable technology, reasonable overall layout, convenient operation and management, and low processing cost, we have compiled this scheme.
According to the information provided by your company, the main pollutant in the flue gas is nitrogen oxide. Nitrogen oxides include a variety of compounds, such as nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen trioxide (N2O3), nitrogen tetroxide (N2O4) and nitrogen pentoxide (N2O5). Except for nitrogen dioxide, other nitrogen oxides are extremely unstable, when light, moisture or heat into nitrogen dioxide and nitric oxide, nitric oxide into nitrogen dioxide. Thus, exposure in the occupational environment is to a mixture of gases commonly called nitrous oxide (gas), mainly nitric oxide and nitrogen dioxide, and mainly nitrogen dioxide. Nitrogen oxides have different degrees of toxicity.
(1) the principle of ammonia denitration is reductive ammonia after on-line system for measuring, dilution, pressure, to the atomization injection system, in addition to the compressed air to spray gun after filtration, voltage regulator, under the action of reducing agent in the compressed air after shower nozzle atomizing spray directly into the furnace, furnace reductive ammonia reaction and NOx, generating no pollution of N2 and H2O.
(2) in furnace and spray gun spraying ammonia reduction nox, due to the high temperature in the furnace, so the reduction of nitrogen efficiency is very low, only part of the reduction of nitrogen oxide, another part of the ammonia under the condition of high temperature reduction of ammonia, ammonia flue gas into the pipeline, with a pipe joint denitration integrated into activated coke tower, tower using activated coke catalytic reduction technology, the tower spray gun spraying ammonia, ammonia water is heated into ammonia and water, ammonia under the action of activated coke and nox reduction reaction, generate nitrogen and water, and is entered into the original desulfurization tower fan emptying directly.The ammonia liquid in the circulating tank is filtered and added to the ammonia tank for recycling.Principle of denitrification reaction: NOX and NH3 can undergo catalytic reduction reaction in the integrated tower of active coke combined denitrification, generating nitrogen and water.
4NO＋4NH3＋O2 → 4N2＋6H2O
6NO2＋8NH3 → 7N2＋12H2O
(3) an online nitrogen oxide monitoring system was added at the outlet of active coke to automatically control the dosage of ammonia and denitrifier.
