The spray grating device has the advantages of simple structure, convenient operation, even mixing, small resistance and large output ability.
Description
Technical field
The utility model relates to a kind of spray grid device, belongs to environmental protection or chemical technology field.
Background technology
In the out of stock technology of flue gas, ammonia and nitrogen oxide mix and the distribution effect is one of key factor that influences the out of stock efficient of flue gas, what generally adopt at present is the method for ammonia-spraying grid, the structure of existing ammonia-spraying grid is mainly some amonia adjutages and is arranged in the flue, the upper end of amonia adjutage is connected with ammonia, air gas mixture supply main, and the lower end then is a cecum; Every amonia adjutage or some amonia adjutages are furnished with the valve that a flow can be regulated separately, have the ammonia spray-hole that some diameters do not wait on each metallic conduit.This ammonia-spraying grid complex structure, inhomogeneous because the control of aperture and valve easily causes ammonia and other gases to mix, particularly, influence mixed effect and increase resistance because the spray direction of nozzle is provided with unreasonablely.
Summary of the invention
In order to overcome the defective of prior art, the utility model provides a kind of spray grid device, simple in structure, easy and simple to handle, mix, resistance is little, fan-out capability is big.
The utility model is achieved through the following technical solutions: a kind of spray grid device, comprise female pipe of housing and interconnective spray and spray arm, the outer end of the female pipe of described spray extends to outside the described housing, described spray arm is provided with several nozzle bores, be positioned at described housing, the spray direction of described nozzle bore is along the axis direction of described housing.
The female pipe of described spray also can be provided with the plurality of nozzles hole, and the spray direction of described nozzle bore is along the axis direction of described housing.
Usually, described spray arm and the female pipe of described spray be in described housing shaft in vertical same plane.
Described spray arm is generally several, is arranged in parallel, and spacing equates between the adjacent arm.
Described spray arm can be symmetrically distributed in the both sides of the female pipe of described spray usually.
Described several nozzle bores can be divided into some groups of nozzle bores, keep at a distance between the two adjacent groups nozzle bore.
Distance between adjacent on the same group two nozzle bores generally should be less than the distance between the two adjacent groups nozzle bore.
The aperture of described each nozzle bore usually can be consistent.
The female pipe of described spray outer end can link to each other with the spray liquid supplying apparatus by pipeline, and valve is installed.
The female pipe of described spray can be fixedly mounted on the described housing by modes such as welding, and the female pipe of described spray connects for welding or by the attaching nut with the connected mode of described spray arm etc.
Effect of the present utility model has been to overcome the structure of traditional ammonia-spraying grid complexity, and the design by rational nozzle spray direction, under the situation that guarantees to mix, reduced the resistance that the ammonia spray causes, possess simple in structure, easy and simple to handle, mix, resistance is little, fan-out capability is big advantage.
Description of drawings
Fig. 1 is a schematic top plan view of the present utility model.
Fig. 2 is that master of the present utility model looks schematic diagram.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model is a kind of spray grid device, comprise a housing 1 that can constitute exhaust gases passes, be welded on the female pipe 2 of spray on the described housing and several and spray spray arms 3 that female pipe communicates, the spray arm is welded on the female pipe of spray, offers several nozzle bores 4 on female pipe of described spray and the spray arm.
According to concentration and the concentration of pressure and mist and the structure that pressure is determined the female pipe of spray described in the ammonia-spraying grid, spray arm of ammonia, the aperture of described nozzle bore and quantity.The opening direction of nozzle bore is consistent with the flow direction of flue gas.
Open the opening valve 5 of the female pipe of spray, extraneous ammonia being pressed into by certain pressure sprays female pipe, the air-flow of described ammonia sprays by the nozzle bore that sprays female pipe along the flow direction of mist subsequently, the air communication of described ammonia is crossed the female through hole of managing and spraying arm of described spray and is entered the spray arm simultaneously, and pass through of the flow direction ejection of the nozzle bore of spray arm along mist, in flue, evenly mix with mist thereby reach ammonia.
The material of described housing, the female pipe of spray and spray arm is the resistance to acids and bases material.
The axis direction of the alleged housing of this specification or housing shaft are to when housing adopts axially symmetric structure, finger is along the direction of this symmetry axis, when the housing employing does not have the structure of symmetry axis, refer to the airflow direction on relevant position when air-flow flows to the housing outlet by the housing import.
The utility model also is applicable to the spray of other gases or liquid.
