Abstract
The utility model provides the dynamic ammonia of a kind of SCR denitration empty blender, by front portion in cylindrical mixing drum 1, ammonia playpipe 3 is housed formed, cylindrical mixing drum 1 front end is air intake, rear end is mixed gas outlet, it is characterized in that: the cylindrical forward and backward two ends of mixing drum 1 are welded with eccentric reducer 2 respectively, its rear inside wall misaligned interval is connected with some guide vanes 4, and ammonia playpipe 3 is located on the axle center of cylindrical mixing drum 1, on its tube wall and is uniformly distributed some spray ammonia holes 5, port closed.There is the advantages such as mixing is abundant, resistance is little.
Description
Technical field
The utility model relates to a kind of gas denitrifying technology field, particularly relates to the empty blender of the dynamic ammonia of a kind of SCR denitration.
Technical background
The empty mixing arrangement of traditional ammonia mainly comprises the empty blender of venturi ammonia and the empty blender of static ammonia.The empty blender of venturi ammonia mainly utilizes ammonia and air hydrodynamic and static pressure pressure reduction in Venturi tube to reach mix uniformly effect, and its major advantage is that device is simple, easy to process.Major defect is that medium easily causes turbulent flow mixed flow when being mixed with, medium undercompounding and evenly, easily causes medium mixed effect poor; The empty blender of static ammonia mainly utilizes cylinder bellows or silk screen ammonia and air to reach mix uniformly effect by physical impacts, and its major advantage is that mixing is abundant, and mixed effect is better.Major defect is that device resistance is large, and medium easily blocks, and energy consumption is high.Above shortcoming limits applying of the empty blender of venturi ammonia and the empty blender of static ammonia.
Summary of the invention
The purpose of this utility model is providing a kind of guide vane formula ammonia empty blender in conjunction with on the empty blender of traditional venturi ammonia and the empty blender advantage basis of static ammonia.
Technical solution of the present utility model is: the empty blender of the dynamic ammonia of a kind of SCR denitration, by front portion in cylindrical mixing drum, ammonia playpipe is housed formed, cylindrical mixing drum front end is air intake, rear end is mixed gas outlet, it is characterized in that: the forward and backward two ends of cylindrical mixing drum are welded with eccentric reducer respectively, its rear inside wall misaligned interval is connected with some guide vanes, and ammonia playpipe is located on the axle center of cylindrical mixing drum, on its tube wall and is uniformly distributed some spray ammonia holes, port closed.
Described guide vane is five pieces, is 75 degree with the angle of the vertical plane through described cylindrical mixing drum axial line.
Described guide vane is semicircle along the projection of shape of cylindrical mixing drum axis.
The utility model compared with the existing technology has:
1, utilize the difference of intake air and ammonia air quantity and pressure, adopt special ammonia playpipe design, ammonia playpipe adopts and evenly opens aperture form, is arranged on the left of facilities air entrance central in cylindrical shell.The porous of ammonia is sprayed a small amount of ammonia and can be evenly ejected in large quantity of air air-flow, and simultaneously because ammonia pressure is higher than air pressure, ammonia fully stirs in atmosphere, better than venturi mixer mix uniformly effect;
2, the half-moon plate type guide vane in mixing drum, relative to static mixer cylinder bellows or silk screen design, gas flow resistance obviously reduces.
3, relative to traditional mixer, this blender has that resistance is little, the advantage of good mixing effect.

The structural representation of Fig. 3 the utility model embodiment guide vane
In figure: 1, cylindrical mixing drum, 2, eccentric reducer, 3, ammonia playpipe, 4, guide vane, 5, spray ammonia hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention is described:
Composition graphs 1, Fig. 2, Fig. 3, the empty blender of the dynamic ammonia of a kind of SCR denitration that the utility model embodiment proposes, cylindrical mixing drum 1 one end is air intake, the other end is mixed gas outlet, its forward and backward two ends are welded with eccentric reducer 2 respectively, periphery of inner wall is provided with five pieces, is the guide vane 4 of 75 degree with the angle of the vertical plane through cylindrical mixing drum 1 axial line, guide vane 4 is semicircle along the projection of shape of cylindrical mixing drum axis, and its outer is corresponding to the inwall of cylindrical mixing drum 1 and weld mutually; Ammonia playpipe 3 to be introduced outward in it by the barrel of cylindrical mixing drum 1 and is arranged on the axle center of cylindrical mixing drum 1, its tube wall is uniformly distributed the spray ammonia hole 5 that some diameters are 10 millimeters, ammonia playpipe 3 port closed,
The design in ammonia playpipe 3 of the present utility model and spray ammonia hole 5, ammonia is made to enter cylindrical mixing drum 1 with ammonia playpipe 3, spray from spray ammonia hole 5 to surrounding, fully mix with the air entered from air intake, and guide vane 4 is provided with on cylindrical mixing drum 1 inwall, the rough air that ammonia and air gas mixture are formed by guide vane 4, make mixing more abundant, and air resistance is little in cylindrical mixing drum 1, exit velocity is larger, and it is better to enter next stage ammonia-spraying grid spray ammonia effect.
