Description
Technical field
The utility model belongs to field of environment protection, is adapted to the purification of boiler smoke and industrial tail gas, is specifically related to a kind of flue gas ash removal denitrification integrated device.
Background technology
NO
xBe directly to cause acid rain, one of major reason of ozone hole and photochemical fog is discharged NO wantonly
xTo cause serious harm to human health and ecological environment, therefore to NO
xImprovement be the emphasis in world environments protection field always.Countries in the world are to NO
xDischarging formulated more and more stricter standard, " thermal power plant's atmosphere pollutants emission standards " (GB 13223-2011) of China's up-to-date promulgation in July, 2011 be to NO
xDischarging also begin to carry out the standard stricter than the past, this has had higher requirement to gas denitrifying technology undoubtedly, therefore, gas denitrifying technology must improve constantly.
For NO in the flue gas
xRemove, generally use selective catalytic reduction (being the SCR method) both at home and abroad.This method removal efficiency is high, and non-secondary pollution can be widely used in the purification of coal-fired flue-gas and industrial tail gas.It mainly is to utilize ammonia to reduce the NO in the flue gas as reducing agent
x, generate H
2O and N
2Thereby, reach and remove NO

(4) the utility model has prolonged the mixed ammonia time greatly under the situation that does not increase device length, compact conformation not only, and can effectively improve NO
xClearance with reduce the escaping of ammonia rate.
(5) when mixed flue gas process venturi passage, because the flue area dwindles suddenly, flue gas flow rate increases, and turbulent flow strengthens, and has further strengthened the mixability of reactant and the uniformity of distribution.When flue gas comes out from the venturi passage, the sudden enlargement of flue area, flue gas flow rate reduces, and is convenient to reactant fully reaction on the denitrating catalyst bed.
(6) the venturi passage becomes 10 ° ~ 40 ° angles with the diametric(al) of housing inner core, and becomes 15 ° ~ 55 ° angles with horizontal plane, can make flue gas get into the housing urceolus with lower drag.Certain distance stretches out to housing inner core center position in venturi feeder connection place, and extension is horizontal arrangement, and the back side is smooth and overarch, and can prevent effectively that the dust that falls from being brought into the housing urceolus by flue gas.Venturi feeder connection and outlet are designed to streamlined, can reduce the equipment crushing greatly, practice thrift operating cost.
(7) flue gas gets into from denitrating catalyst bed bottom, and dust is not easy to be accumulated on the beds, makes the beds deashing become easier simultaneously.
(8) the denitrating catalyst bed is distributed in the annular space between outer tube wall and the inner tube wall radially; With respect to isopyknic cylindricality catalyst, the span of smoke distribution reduces, and reactant absolute concentration difference will reduce greatly; Thereby can make full use of whole catalyst, improve and remove NO
xRemove efficient, reduce the escaping of ammonia rate.
