Problems solved by technology

[0002] The variety of heat treatment process types and the shape and size of the heat treatment workpiece, the heat treatment furnace furnace type and structure are also various. The heat treatment furnace refers to the electric furnace or fuel furnace used for heat treatment and heating of the charge. A large amount of pollutants will be avoided, and air pollutants will harm human health: polluted air has a direct impact on human health; factories have not only concentration requirements for nitrate emissions, but also total requirements. The traditional denitrification system has the disadvantages of high equipment investment and large floor area. In addition to denitrification, it can also remove other harmful gases in the flue gas, such as sulfur, mercury and other substances. Ozone oxidation with a small footprint Low temperature and low concentration flue gas denitrification system is very important

Abstract

The invention discloses a low-temperature flue gas ozone denitration system, and belongs to the field of flue gas denitration. The low-temperature flue gas ozone denitration system comprises a spray purification tower; an ozone feeding and mixing device is connected to an inlet of the spray purification tower; an ozone device of which the output end is connected with the ozone feeding and mixing device; a waste gas inlet pipe connected with the ozone feeding and mixing device; an air outlet pipe connected to the upper end of the spray purification tower; a circulating water tank, of which thewater outlet end is connected with the spray pipe in the spray purification tower and the water inlet end is connected to the lower end of the spray purification tower. The waste gas inlet pipe is connected to a smoke outlet of the heat treatment furnace for cooling the flue gas to below 80 DEG C and feeding the flue gas into the ozone feeding and mixing device; meanwhile, ozone is generated through the ozone device, is conveyed into the ozone feeding and mixing device and is absorbed by an alkaline solution through the spraying purification tower, so that denitration is achieved. The system is small in occupied area, small in investment and high in low-concentration nitrogen oxide treatment efficiency.
