Abstract
The utility model discloses an atomizing spray gun, it includes shower nozzle and spray gun body, establishes the atomizing hole on the shower nozzle, atomizing spray gun includes still that one end establishes the forcing pipe in the shower nozzle, establishes the pressurization hole on the forcing pipe pipe wall in the shower nozzle. Establish the forcing pipe in atomizing spray gun's spray tube, can make atomization efficiency improve, prevent the jam of spray tube and shower nozzle.
Description
Technical field
The utility model relates to a kind of atomizing lance, particularly a kind of atomizing lance for denitration, belongs to dry powder denitration field.
Background technology
Denitration refers in combustion product gases the process removing nitrogen oxide.For preventing producing too much nitrogen oxides pollution environment in boiler after coal combustion, reply flue gas carries out denitration process.
Denitrating flue gas generally needs to spray denitrfying agent to kiln or boiler, and denitrfying agent makes powdery, by compressed air delivery, then atomization spray in stove with the reaction of nitrogen oxides in flue gas.Denitrfying agent after using existing atomizing lance to be atomized, its particle size is not suitable for, and easily blocks jet pipe and shower nozzle, and particularly for the material that ratio of viscosities is larger, atomizing effect is bad.
Utility model content
The technical problem that the utility model solves is, what prevent denitrfying agent blocks jet pipe and atomizer because viscosity is large, improves the nebulization efficiency of atomizing lance.
The technical solution of the utility model is, provides a kind of atomizing lance, comprises shower nozzle and gun body, shower nozzle establishes orifice, and described spray gun also comprises one end and is located at forcing pipe in shower nozzle, the forcing pipe tube wall in shower nozzle is established pressurization hole.
Further, the aperture in described pressurization hole is 0.5 ~ 50mm.
Further, the number in described pressurization hole is 1 ~ 50.
Further, the aperture of described orifice is 0.1 ~ 50mm.
Further, the number of described orifice is 1 ~ 100.
Further, described gun body comprises jet pipe and is enclosed within the flange on jet pipe.
Further, the caliber of described jet pipe is 2 ~ 5 times of forcing pipe caliber.
The atomizing lance that the utility model provides, its course of work is, denitrfying agent and compressed air is passed into from the jet pipe of atomizing lance, and is fed to the shower nozzle of atomizing lance; Simultaneously, a forcing pipe is also communicated with in shower nozzle, the compressed air that pressure is larger is passed in forcing pipe, from the pressurization hole ejection forcing pipe tube wall, two parts compressed air produces strong convection current in shower nozzle, denitrfying agent is fully disperseed, and by being passed in boiler after the orifice atomization on shower nozzle.Wherein, number and aperture foundation the different of material of pressurization hole and orifice are designed, and general aperture is below 50mm; Pressurization number of perforations is 1 ~ 50, and the number of orifice can reach 100.Because forcing pipe is enclosed within jet pipe inside, jet pipe also needs conveying denitrfying agent and compressed air, therefore 2 ~ 5 times of the caliber of jet pipe preferably forcing pipe caliber.The flange be enclosed within jet pipe may be used for the fixing of jet pipe and the connection with other pipelines.
The beneficial effects of the utility model are, in the jet pipe of atomizing lance, establish forcing pipe, nebulization efficiency can be made to improve, prevent the blocking of jet pipe and shower nozzle.
Accompanying drawing explanation
Fig. 1 represents the schematic perspective view of the atomizing lance that the utility model provides.
Fig. 2 represents the front view of the atomizing lance that the utility model provides.
Fig. 3 represents the sectional view of the atomizing lance that the utility model provides.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of atomizing lance, and as shown in Figure 1, its front view as shown in Figure 2, comprises shower nozzle 1 and gun body 2, shower nozzle 1 established orifice 3 its stereochemical structure; As shown in Figure 3, atomizing lance also comprises one end and is located at forcing pipe 4 in shower nozzle 1 sectional view, forcing pipe 4 tube wall in shower nozzle 1 is established pressurization hole 5.The number of the orifice 3 of this atomizing lance is 20, and aperture is 4mm; The number in pressurization hole 5 is 15, and aperture is 2mm.The caliber of forcing pipe is 3cm, and the caliber of jet pipe is 9cm.This atomizing lance is used for the atomization of dry powder denitrfying agent, can not block jet pipe and shower nozzle, atomizing effect is fine.
