Description

Water-saving overflow pipeline and vacuum pump steam-water separator with same

Technical Field

The utility model belongs to the technical field of catch water's overflow, concretely relates to water conservation overflow line and have vacuum pump catch water of water conservation overflow line.

Background

The vacuum pump steam-water separator now in use is a conventional bottom-ported, top-flooded style, as shown in FIG. 1. When the overflow mode is adopted, the condition of a large amount of waste make-up water exists in the operation process of the steam-water separator of the vacuum pump. Because, after the vacuum pump catch water rises and forms the overflow owing to the water level, the overflow pipe can form siphonage, makes the water in the vacuum pump catch water continuously flow out along the overflow pipe, leads to catch water to be in the moisturizing state all the time, and catch water overflow mouth is in the overflow state all the time. In the operation mode, a large amount of make-up water is wasted, and the low liquid level of the steam-water separator of the vacuum pump is easy to cause the efficiency of the vacuum pump to be reduced and even the vacuum of the generator set to be suddenly reduced. There are major disadvantages to the safe and economic operation of the generator set.

Disclosure of Invention

Compared with the prior art, the utility model discloses following profitable technological effect has at least:

the siphon breaking pipe is connected to an overflow pipeline of the vacuum pump steam-water separator, the vacuum pump steam-water separator can overflow normally when the liquid level rises, and when the liquid level exceeds the overflow control water level, the siphon breaking pipe plays a role in breaking the siphon phenomenon of the overflow pipe of the vacuum pump steam-water separator. Normal water supplement of the steam-water separator of the vacuum pump of the unit can be ensured through the overflow pipeline, the operation safety of the vacuum pump is ensured, the water supplement amount of the steam-water separator can be reduced, and the water preparation cost, the power generation water supplement cost and the plant power consumption of a power plant are saved; meanwhile, the labor intensity of operators for frequently adjusting the steam-water separator of the vacuum pump is reduced.

Further, the overflow pipe is the U-shaped, and the advantage that vacuum pump catch water overflow pipe set up to the U-shaped pipe lies in that catch water inner overflow pipe one end is in below the liquid level all the time, and when catch water kept certain liquid level, catch water overflow pipe can remain throughout and isolated with the atmospheric environment, prevents that the unit vacuum from falling suddenly.

Further, the siphon destroys and is provided with the valve on the pipe, and under normal use condition, the siphon destroys the normal door on the pipe and keeps open state, when needs overhaul or when looking for the hourglass, closes the valve, prevents that water from destroying the pipe outflow from the siphon.
