Abstract
The utility model discloses a sintering gas desulfurization and denitration integrated device comprising a tower body, wherein the upper end of the tower body is provided with a smoke outlet; the device is characterized in that the lower end of the tower body is installed with a cyclone volute chassis which is internally provided with an upturned sprayer; the side and the lower end of the cyclone volute chassis are respectively provided with a smoke inlet and a waste liquid outlet; the middle of the tower body is provided with a filter screen; a demister is arranged above the filter screen; and a treating fluid circulating device is connected between the inlet of the sprayer and the waste liquid outlet. A great amount of fine foam is formed by the impact of the seriflux on the filter screen, when the sintering gas passes through the foam surrounding the filter screen, SO2 and NOX in the gas react with the desulfurization and denitration agent in the foam, the generated desulfurization by-product gypsum is crystallized and separated out under working conditions, the generated denitration by-product sodium nitrate is crystallized by cooling and separated out, and the desulfurization and denitration liquid is reused through a closed cycle device. The device has simple structure and good desulfurization and denitration effects.
Description
Technical field
The utility model relates to environment protection equipment, specifically is a kind of sintering flue gas desulfurization denitrification integrated device, is mainly used in coal-fired sintering furnace and other coal-burning installations purified treatment to the discharging flue gas.
Background technology
At present, in flue gas desulfurization technique, wet desulphurization accounts for about 82% of world market, in wet desulphurization again based on the calcium method.The advantage of calcium method desulfurization is removal efficiency and sorbent utilization height, but also has the easy fouling of equipment, obstruction, causes problems such as system can't move.Denitration technology is then maximum with the research of the catalytic reduction method in the dry method, but adopts reducing process to remove NO
X, not only the nitrogen resource can not be reclaimed, but also a large amount of reducing agents will be consumed, cause the wasting of resources.While SO
2Coexistence easily make the NO catalyst poisoning, this is a unsolved for many years in the world difficult problem.The oxidant costliness is used in the oxidizing process denitration of exploitation at present then ubiquity, even the gaseous oxidant of some employing is in the equipment problem such as potential safety hazard that exists in service.In addition, existing flue gas desulfurization and denitrification technology is the classification processing mode, and classification handles that not only floor space is big, system complex, and equipment investment and operation and maintenance cost height.
Summary of the invention
Problem to be solved by this invention provides a kind of removal efficiency height, investment and operating cost is low, can carry out the integrated apparatus of flue gas desulfurization and denitrification simultaneously.
The technical solution of the utility model is: comprise tower body, upper end at this tower body is provided with exhaust opening, it is characterized in that: whirlwind spiral case chassis is housed in the lower end of described tower body, in this whirlwind spiral case chassis, be provided with shower nozzle up, be respectively equipped with into mouth and waste liquid outlet in the side and the lower end on this whirlwind spiral case chassis; Middle part in described tower body is provided with screen pack, is provided with demister above this screen pack; Between the inlet of described shower nozzle and waste liquid outlet, be connected with the treatment fluid EGR.
Described screen pack is conical, one or more layers, mesh is circular.
Above described demister, be provided with running water and clean shower nozzle.
Described treatment fluid EGR comprises slurries circulatory pool, medicament pond and hydraulic pump, sedimentation basin be located at described waste liquid outlet below, be provided with the medicament pond on the next door of this sedimentation basin, this sedimentation basin communicates with the bottom in medicament pond; Be connected hydraulic pump between the inlet of this medicament pond and shower nozzle.
The utility model advantage is: the flue gas by tower body spiral case chassis side tangentially enters can evenly distribute soup foam adhesion that flue gas is sprayed by shower nozzle and the SO in its flue gas in uphill process in tower body
2, NO
XReaction reaches the effect of desulphurization denitration.In addition, treatment fluid recycles the expense of having saved.
