Detailed description of the invention
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises water tank 9, and the water outlet of water tank 9 connects one end of water supply pipe 16, and water supply pipe 16 other ends connect coolant outlet pipe 8, and coolant outlet pipe 8 ends are provided with shower nozzle.When normal work, the water in water tank 9 enters shower nozzle by water supply pipe 16 and coolant outlet pipe 8 and sprays.Water supply pipe 16 is provided with high pressure pump 15, and high pressure pump 15 is squeezed into the water pressurization in water tank 1 in shower nozzle and sprayed, and water is not easy to remain in water pipe.
On coolant outlet pipe 8, connect the second return water pipe 13, the second return water pipes 13 by the second T-pipe joint 17 and connect vacuum pump 12, on vacuum pump 12, connect water tank 9 by the first return water pipe 11.Described the second return water pipe 13 is provided with the 3rd switch valve 14, the first return water pipes 11 and is provided with second switch valve 10.When fog system quits work, vacuum pump starts, and the 3rd switch valve is opened, and the water in coolant outlet pipe is withdrawn in water tank, until lack of water extracts to support vacuum pump in coolant outlet pipe, vacuum pump quits work, and remains in water in pipe by part sucking-off.
On coolant outlet pipe 8, connect the second tracheae 4, the second tracheaes 4 by the first T-pipe joint 7 and connect storage tank 3, storage tank 3 connects Air compressor 1 by the first tracheae 2.Described the second tracheae 4 is provided with the first switch valve 5.Air compressor 1 is by air compressing, and the air after compression is blown and beaten away the water remaining in coolant outlet pipe by shower nozzle, guarantees in coolant outlet pipe no longer residuary water.
Described coolant outlet pipe 8 outside faces are laid silaatic ribbon heater 6, and whole process heating is carried out to coolant outlet pipe 8 in silaatic ribbon heater 6, is conducive to residual evaporation of water in pipe, also can prevent body bursting by freezing.
Described the first switch valve 5 is motorized valve, and second switch valve 10 is hand valve, and the 3rd switch valve 14 is motorized valve.
Principle of work of the present invention is: while normally work, the water in water tank enters shower nozzle by water supply pipe and coolant outlet pipe and sprays.When fog system quits work, vacuum pump starts, and the 3rd switch valve is opened, and the water in coolant outlet pipe is withdrawn in water tank, until lack of water extracts to support vacuum pump in coolant outlet pipe, vacuum pump quits work.Now Air compressor starts, and by the air extrusion of compression, in storage tank, the first switch valve is opened, and the air after compression is blown and beaten away the water remaining in coolant outlet pipe by shower nozzle, guarantees in coolant outlet pipe no longer residuary water.Wherein silaatic ribbon heater omnidistance energising heating in fog system and the antifreeze support system work of spraying, has fundamentally solved in dome coal store storehouse dedusting fog system and has stopped up the problem that cannot work because of frost crack pipe and shower nozzle.At high service, vacuumize, pressurized air purge and the effect of shower nozzle loop heating insulation multi-functional under, guarantee that atomizing de-dusting pipeline loop and shower nozzle can not freeze and stop up under severe cold condition, realized spray dust-reducing system round-the-clock continuous operation under various working conditions.
