FIG. 1 shows a flushing head for a nuclear power plant;
in the figure: 1-a water inlet pipeline 2-a fixed flange 3-a waste liquid inlet; 4-a waste liquid storage tank; 5-a sewage draining outlet; 6-manhole; 7-an electric pan-tilt; 8-spray header.
Detailed Description
The present invention will be further explained with reference to the drawings and the detailed description.
As shown in fig. 1, the washing pan-tilt for the nuclear power station comprises a water inlet pipeline 1 arranged on one side of a waste liquid storage tank 4, and an electric pan-tilt 7 and a spray header 8 arranged at the end part of the water inlet pipeline 1.
The upper end of the waste liquid storage tank 4 is provided with a waste liquid inlet 3, and the lower end is provided with a sewage outlet 5.
The water inlet pipe 1 extends into the waste liquid storage tank 4 through a manhole 6 at one side of the waste liquid storage tank 4. The end of the water inlet pipeline 1 is provided with a spray header 8, one end of the water inlet pipeline 1 is connected with an external water source, and the other end of the water inlet pipeline is provided with the spray header 8 to form a flushing pipeline. The spray header 8 sprays the waste liquid in the waste liquid storage tank 4, and the demineralized water atomization is carried out, so that the spray area is increased. The atomized waste liquid is discharged through a sewage outlet 5 at the lower end.
Preferably, the spray head 8 adopts an integrated metal fan-shaped spray head, and the rated flow rate is 15L/min under 1 MPa.
Preferably, the shower head 8 sprays water at an angle (angle of spraying direction to the pipe line) of 40 to 65 °, and more preferably 45 to 50 °.
In order to rotate the spray header 8, the water inlet pipeline 1 and the electric holder 7 can be connected through a bolt, the electric holder 7 and the spray header 8 are connected through a buckle, and the spray header 8 is driven to rotate when the electric holder 7 rotates.
