Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a humidifier with a simplified piping system, particularly a humidifier for a nuclear power plant.

[Conventional technology]

FIG. 4 shows an explanatory diagram of a conventional humidifier for nuclear power plants. As shown in Figure 4, in the conventional humidifier for nuclear power plants, the steam line 1 of the auxiliary steam equipment
Humidifying steam is supplied to the air to be humidified from 6 through a steam pipe 12, which is a double inner pipe, extending through the humidifier main body 11. On the other hand, the excess steam is condensed in the condensate pipe 13 and collected together with the generated condensate into the condensate pipe 13 which is the outer pipe of the double pipe, and the condensate pipe is connected to the condensate pipe 13 outside the humidifier main body 11. It flows through the nozzle 15 to the condensate recovery line 18 of the auxiliary steam facility and is recycled. Further, a drain nozzle 14 is attached to the humidifier body 11 to drain generated condensed water, and the humidifier body 11 is secured with a cap. If drain accumulates inside the humidifier body 11, the cap is removed and the drain water is collected in a tray or the like.

[Problem that the invention attempts to solve]

In conventional humidifiers, a condensate pipe nozzle is installed outside the humidifier main body, and this is communicated with a condensate pipe and connected to a condensate recovery line, which requires space for installing the pipe. Also, condensate water that can be recovered
It is necessary to construct a condensate line from the condensate pipe nozzle to the collection drain tank, which is relatively large compared to the amount of steam. In addition, the condensate line and the drain line for the humidifier are separate systems, so the piping system is not simple, and if drain water accumulates in the humidifier, it must be collected manually. There is a problem.

It is an object of the present invention to provide a humidifier that improves the drawbacks of the conventional humidifier and has a simplified piping structure around the humidifier.

[Means for solving problems]

The present invention is a steam pipe that is installed through the humidifier main body, the inner pipe is a perforated pipe for supplying steam into the humidifier main body, and the outer pipe is a perforated pipe for collecting condensate water. In a humidifier that supplies steam to the double-pipe steam pipe to humidify the air inside the humidifier body, a condensate pipe nozzle communicating with the condensate pipe is provided inside the humidifier body, and the condensate pipe nozzle is provided inside the humidifier body. There is a gap in the drain nozzle that opens near the bottom of the humidifier body.
The present invention proposes a humidifier characterized in that the humidifier is provided with an extended opening.

[Effect]

The condensate pipe nozzle outside the humidifier body is installed inside the humidifier body so as to connect to the drain nozzle on the humidifier body, and the piping structure around the humidifier is simplified by eliminating the condensate pipe nozzle outside the humidifier body. can be converted into

〔Example〕

An embodiment of the present invention will be explained with reference to FIGS. 1 to 3. FIG. 1 is an explanatory diagram of an embodiment of the present invention, FIG. 2 is a cross-sectional view taken from FIG. 1, and FIG. 3 is an enlarged view of section A in FIG. In Figure 1, 1 is the humidifier main body, 2 is the inner pipe of the double pipe that penetrates the humidifier main body 1 and is a steam pipe with a hole in the pipe wall, and 3 is the outer pipe of the double pipe. A condensate pipe having a hole in the pipe wall, 4 a drain nozzle opened at the bottom of the humidifier body 1, 5 a
A condensate pipe nozzle communicates with the condensate pipe 3 and is provided inside the humidifier main body 1 and extends to and opens at the drain nozzle 4, 6 is a steam line, and 7 is a drain pipe connected to the drain nozzle.

Figure 2 is a cross-sectional view of a double pipe, where 2 is a steam pipe, 2' is a steam jet hole drilled in the steam pipe, and 3 is a steam pipe.
is a condensate pipe, and 3' is a steam supply hole bored in the condensate pipe. Steam supplied from the steam line 6 flows through the steam pipe 2, and is ejected from the steam jet hole 2' of the steam pipe 2 into the condensate pipe 3 as shown by the arrow in FIG.
Furthermore, the humidifier main body 1 is
supplied within. On the other hand, excess steam is transferred to condensate pipe 3
It is discharged to the drain pipe 7 through the condensate pipe nozzle 5 along with the condensate generated by condensation within.

Further, as shown in FIG. 1, the condensate pipe nozzle 5 is provided inside the humidifier main body 1 and is attached in such a way that it is connected to the condensate pipe 3 and the drain nozzle 4 of the humidifier main body 1. At this time, the drain nozzle 4 and the condensate pipe nozzle 5 should not be connected in a close contact manner, but should be spaced apart as shown in FIG. 3. This is to prevent the pressure in the condensate pipe 3 from being directly transmitted to the building floor drainage system via the drain removal nozzle 4. A drain pipe 7 to a building floor drainage system is connected to the drain nozzle 4.
As a result, the condensate drain of auxiliary steam from the condensate pipe nozzle 5 and the drain generated in the humidifier main body 1 can be collectively and automatically drained to the building floor drainage equipment.

[Effect of idea]

According to the humidifier of the present invention, (a) The piping system of the condensate line from the condensate pipe nozzle of the auxiliary steam equipment to the drain tank can be shortened and significantly reduced.

(b) What used to be two systems, the condensate line and the drain line of the humidifier body, can be combined into one system.

(c) Drain water generated in the humidifier body can also be automatically drained at the same time.

It has a unique effect.
