Description
Technical field
The utility model belongs to equipment for denitrifying flue gas technical field, is specifically related to a kind of equipment for denitrifying flue gas of cement kiln associated treatment rubbish technique.
Background technology
China is as manufacture of cement the world's strongest nation, have nearly 5,000 of cement production enterprise at present, production capacity accounts for more than sixty percent of global total output, about 1,600,000 tons of cement industry nitrogen oxide, account for about 1/10th of nitrogen oxide total release, according to " cement industry " 12 " development plan ", along with cement industry backward production facilities eliminate the propelling nitrogen oxide of work as one of main atmosphere pollution, be the object of national strict control discharge after sulfur dioxide.The most widely used gas denitrifying technology of present cement industry is SCR technology and SNCR technology, and SCR technology denitration efficiency can reach more than 95%, but invests large due to it, system complex, catalyst life is short, and operating cost is high, and is not suitable for the cement kiln of low temperature low-sulfur.And although SNCR technology is invested low, operating cost is few, and system is simple, and applied widely, its fatal defect is exactly that denitration efficiency is low, only has 30%-50%, far can not reach the standard of discharge.In addition, in cement kiln tail dore furnace flue gas, NOX concentration is higher, contains the harmful substances such as dioxin, heavy metal ion and sour gas simultaneously, all can not well be removed by above-mentioned two kinds of methods in cement kiln associated treatment rubbish kiln kiln exit gas.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, and provide a kind of structure simple, effectively can remove the equipment for denitrifying flue gas of a kind of cement kiln associated treatment rubbish technique of the harmful substances such as dioxin, heavy metal ion and the sour gas in cement kiln tail gas.
The purpose of this utility model is achieved like this: comprise SCR reactor body, the bottom of SCR reactor body and top are respectively equipped with gas approach and exhanst gas outlet, the bottom of SCR reactor body is provided with filtering meshes, the top of filtering meshes is provided with NaOH spray, the top of NaOH spray is provided with activated carbon adsorption layer, the first catalyst layer and the second catalyst layer successively, and the first described catalyst layer and the second catalyst layer are equipped with reactant shower nozzle.
It is simple that the utility model has structure, effectively can remove the advantage of the harmful substances such as dioxin, heavy metal ion and the sour gas in cement kiln tail gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is a kind of equipment for denitrifying flue gas of cement kiln associated treatment rubbish technique, comprise SCR reactor body 1, the bottom of SCR reactor body 1 and top are respectively equipped with gas approach 2 and exhanst gas outlet 3, the bottom of SCR reactor body 1 is provided with filtering meshes 4, the top of filtering meshes 4 is provided with NaOH spray 5, the top of NaOH spray 5 is provided with activated carbon adsorption layer 6, first catalyst layer 7 and the second catalyst layer 8 successively, and the first described catalyst layer 7 and the second catalyst layer 8 are equipped with reactant shower nozzle 9.
Operation principle of the present utility model is, the utility model is contained on SCR denitration tower, the waste gas that SCR denitration tower produces enters in SCR reactor body 1 by the gas approach 2 of the bottom of SCR reactor body 1, flue gas is moved upward by filtering meshes 4, filtering meshes 4 can filter out the dust in flue gas, the sodium hydroxide solution of NaOH spray 5 ejection effectively can remove the sour gas in flue gas, activated carbon adsorption layer 6 effectively can adsorb aldehyde phenols pernicious gas, first catalyst layer 7 and the second catalyst layer 8 are equipped with reactant shower nozzle 9, the ammoniacal liquor that reactant shower nozzle 9 sprays effectively can remove nitrogen oxide, last flue gas is discharged by exhanst gas outlet 3.
The utility model by setting up NaOH spray 5 and activated carbon adsorption layer 6 in SCR reactor body 1, the harmful substances such as the dioxin in flue gas, heavy metal ion and sour gas are effectively addressed, and the environmental protection greatly facilitating cement industry develops in a healthy way.
Detailed description is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, allly do not depart from equivalent implementations that the utility model skill spirit does, change and transformation all should be included within protection domain of the present utility model.
