The water inlet, the water outlet are connected to the water supply interface of double medium spray guns；The first valve is provided on the jet chimney
Door component, and jet chimney is connected to the air inlet, the gas outlet is connected to the air feed interface of double medium spray guns.
Further, the water inlet is in the staving lower end, and the water outlet is in staving upper end.
Further, the air inlet is in the staving upper end, and the gas outlet is in staving lower end.
Further, the jet chimney is parallel with nitrogen pipeline, and the second valve group is provided on the nitrogen pipeline
Part.
Further, the quantity of the attachment net is three.
Compared with prior art, the advantageous effects of the utility model are as follows:
For the utility model by the way that water is introduced into apparatus for eliminating sludge before entering double medium spray guns, steam enters apparatus for eliminating sludge
In the snorkel that spirals water is heated, water generates scale after being heated, and it is online to be attached to attachment, is lowered into double media
The scale of water in spray gun extends double medium spray gun service lifes.

Specific embodiment
As shown in Figure 1, 2, a kind of to extend double medium spray guns using the specific embodiment of the steel mill dust pelletizing system of time, it wraps
The double medium spray guns 2 for including devaporizer 1 and being mounted on the devaporizer 1, this is the prior art, no longer superfluous herein
It states.It in addition to this, further include cold water storage cistern 3 and jet chimney 4.There is water inlet pipe 5 and water supply pipe 6, for mending on the cold water storage cistern 3
Water-filling source.Cold water storage cistern 3 is communicated with apparatus for eliminating sludge 8 by evaporating water supply pump 7, and the apparatus for eliminating sludge 8 includes closed staving 801,
The snorkel 803 that vertical spacing is mounted on three attachment nets 802 inside the staving 801 and spirals inside staving 801, leads to
Tracheae passes through attachment net when encountering attachment net.The air inlet 804 of the snorkel 803 and gas outlet 805 are pierced by staving
801 side walls, the air inlet 804 is in 801 upper end of staving, and the gas outlet 805 is in 801 lower end of staving.801 side wall of staving
On be also provided with water inlet 806 and water outlet 807, the water inlet 806 exists in 801 lower end of staving, the water outlet 807
801 upper end of staving.When manufacture, after can first installing staving internal part, then staving closed.The evaporation water supply pump 7
