The utility model discloses further set up to: be provided with coupling assembling between shower and the hydrophobic flash tank body, coupling assembling includes barrel and first ring dish, the both ends opening of self axis direction is followed to the barrel, and the axis level of barrel, the one end and the hydrophobic flash tank body fixed connection of barrel, and the inside intercommunication of barrel and hydrophobic flash tank body, the one end fixed connection some second ring dishes of hydrophobic flash tank body are kept away from to the barrel, be connected with connecting bolt between first ring dish and the second ring dish, first ring dish is located the one end that hydrophobic flash tank body was kept away from to the barrel, the shower passes the ring dish and is connected with the ring dish.

Through adopting above-mentioned technical scheme, unscrew connecting bolt, first ring dish can be dismantled with the second ring dish for can unpack apart between first ring dish and the barrel, can make first ring dish and shower pass through the barrel and take out from this internal hydrophobic flash tank, be convenient for wash and change the shower at this moment.

The utility model discloses further set up to: the water spray holes are uniformly distributed in the vertical part of the spray pipe in the drainage flash tank body.

Through adopting above-mentioned technical scheme, the evenly distributed of hole for water spraying makes shower spun water comparatively even.

The utility model discloses further set up to: the bottom of the spray pipe is sealed.

Through adopting above-mentioned technical scheme, hydroenergy can all follow the hole for water spraying blowout, and can not flow from the bottom of shower to guaranteed the water of equal volume, the water of following the hole for water spraying blowout can have great area of contact with steam.

The utility model discloses further set up to: the water source is demineralized water.

Through adopting above-mentioned technical scheme, the tear content in the hydrophobic that the process demineralized water sprays and the condensation gets off is lower, is difficult for becoming the incrustation scale that thermal conductivity is relatively poor on the heating surface of boiler to avoid the efficiency of boiler to be influenced, make hydrophobic can be better send into the boiler in continue to use.

To sum up, the utility model discloses a beneficial technological effect does:

1. by arranging the spray pipes and the water spray holes, the discharge amount of steam is reduced, and the recovery rate of drainage is improved;

2. through setting up coupling assembling, make first flange and shower take out from this internally of hydrophobic flash vessel through the barrel, be convenient for wash and change the shower.
