The utility model discloses simple structure, nitrify that the treatment effect is good, the usage is extensive, be convenient for to the gaseous centralized processing after handling.
Description
Technical field
The utility model relates to denitrification apparatus, relates in particular to a kind of for flue gas denitrification system.
Background technology
Containing a large amount of nitrogen oxide in the combustion product gases of fuel, wherein NOx is one of main source of atmosphere pollution, if not treated, discharge beyond standards, the environmental pollution such as acid rain and photochemical fog can be caused, affect environment for human survival, cause huge harm to environment.At present, the method for denitrating flue gas mainly contains SNCR method, wherein SCR denitration reaction unit mainly comprises reactor shell, catalyst, enclosure interior comprise supporting construction, sealing device etc.Existing denitrating flue gas purification tower device, such as Chinese utility model patent, notification number: CN203737106U, name is called: a kind of denitrating tower, it comprises tower body, in the lower end of described tower body and upper end, there is air inlet and gas outlet respectively, catalyst looped network is provided with in described tower body, denitrfying agent adsorption chamber and multilayer denitration ring, described catalyst looped network and described denitrfying agent adsorption chamber are located at the inner central region of described tower body and lower area respectively, the inwall of described tower body is provided with support rack, described denitration is located on described supporting network, owing to adopting single tower structure, if the place that flue gas flow is less can process very well, but, if larger for flue gas flow, because all fume centralizeds are by tower, may due in tower the processing time too short, the incomplete defect of gas cleaning process, therefore, develop that a kind of nitrated treatment effect is good, purposes is wide, the simple denitrification apparatus of equipment has great importance.
Utility model content
It is good, broad-spectrum for flue gas denitrification system that the technical problems to be solved in the utility model is to provide a kind of nitrated treatment effect.
For achieving the above object, the utility model provides one for flue gas denitrification system, and comprise denitrating tower, intake stack, wind pipe, supporting frame, described denitrating tower quantity is multiple, is that many denitrating towers are in parallel; The air inlet of described intake stack and described denitrating tower is tightly connected; The inner catalyst filling layer of described denitrating tower; Described denitrating tower is placed on supporting frame; Air outlet and the wind pipe of described denitrating tower are tightly connected.
As preferably, proportional for ensureing catalyst amounts and import flue gas flow, ensure that smoke catalytic process more thoroughly, described catalyst layer quantity is more than one.
More preferably, install or check denitrating tower inner case for the ease of being convenient in conventional operational or installing replacing catalyst layer, described denitrating tower is provided with catalyst and installs door.
As preferably, for the ease of controlling flue gas flow direction, the air inlet of described denitrating tower is provided with air-valve, according to circumstances can control flue gas like this and enter one of them denitrating tower.
The beneficial effect that the utility model has is: 1, adopt denitrating tower in parallel, the flow of flue gas in intake stack can be shunted well, flue gas flow dispersion enters denitrating tower, in denitrating tower, the processing time is longer, more thorough, avoid fume centralized to enter a denitrating tower and processing time less insufficient defect; 2, adopt the opening and closing of air-valve to control the flow direction of flue gas, optionally enter one of them denitrating tower, excessive or too smallly can effectively to process well for flue gas flow; 3, denitrating tower inner catalyst layer can carry out certain linear design according to flue gas flow, and make catalyst fully can meet the needs of smoke catalytic, nitrated process is better; 4, all gas after the nitrated process of denitrating tower, is concentrated and is discharged by wind pipe, is conducive to the collection to gas or other process.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is utility model works schematic flow sheet.
In figure: 1, denitrating tower; 2, intake stack; 3, air-valve; 4, wind pipe; 5, supporting frame; 6, door installed by catalyst.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model one is used for flue gas denitrification system, and it comprises denitrating tower 1, intake stack 2, wind pipe 4, supporting frame 5, and described denitrating tower 1 quantity is multiple, is many denitrating tower 1 Parallel Designs; Intake stack 2 is tightly connected with the air inlet of described denitrating tower 1; Denitrating tower 1 inner catalyst filling layer (not shown in FIG.); Denitrating tower 1 is placed on supporting frame 5; Air outlet and the wind pipe 4 of denitrating tower 1 are tightly connected.
As shown in Figure 2, utility model works flow process is as follows: flue gas enters this intake stack 2 from the air inlet of intake stack 2, thus enter in denitrating tower 1, catalytic treatment is carried out in denitrating tower 1, discharged by wind pipe 2 after process, owing to have employed many denitrating tower 1 Parallel Designs, flue gas enters in denitrating tower 1 by the air inlet of each denitrating tower 1, therefore, a large amount of flue gases will be shunted to enter in each denitrating tower 1 and process, process in same denitrating tower 1 is entered compared with all fume centralizeds, owing to have employed shunting, flue gas separately enters in each denitrating tower 1, therefore flue gas in each denitrating tower 1 is just by dispersion treatment, flue gas in each denitrating tower 1 is less, processing time is more abundant, better compared with original same denitrating tower treatment effect.
Proportional for ensureing catalyst amounts and import flue gas flow, ensure that smoke catalytic process more thoroughly, described catalyst layer quantity is more than one.
Install or check denitrating tower inner case for the ease of being convenient in conventional operational or installing replacing catalyst layer, described denitrating tower 1 is provided with catalyst and installs door 6
Install or check denitrating tower inner case for the ease of being convenient in conventional operational or installing replacing catalyst layer, the air inlet of described denitrating tower 1 is provided with air-valve 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
