Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a steam/water separator having a water supply port and a concentrated water blow port.

(Prior art) Conventionally, an upper header and a lower header are formed in an annular shape,
In small capacity boilers where the upper and lower headers are connected by multiple water pipes, water is supplied to the lower header.

It is common to blow concentrated water from a steam separator or downcomer.

However, the conventional method involves supplying water to the lower header and simultaneously injecting chemicals to prevent corrosion.

This is because the low temperature water supply slows down the chemical reaction rate.

The anticorrosion effect of chemicals was halved, and low-temperature corrosion and pitting occurred around the water supply.

(Objective of the Invention) The present invention aims to improve the problems pointed out in the above section of the prior art, and provides a steam and water separator for the first passenger boiler that has corrosion prevention, concentrated water blowing, and steam and water separation functions. The purpose is to provide

(Means for Achieving the Object) As a means for achieving the above object of the present invention, a water supply port is provided at the bottom of the steam water separator, a concentrated water blow port is provided at the top of the steam water separator, and the steam and water separator is separated. A partition plate and a water circulation prevention plate are provided between the water supply port and the concentrated water blow port inside the container.

(Function) In the present invention, when water is supplied to the water supply port at the bottom of the steam-water separator by the above-mentioned means, it rapidly mixes with the circulating water at the bottom of the steam-water separator and becomes high-temperature water, which speeds up the chemical reaction rate. , the effect of preventing low-temperature corrosion and pitting of the boiler body can be obtained. Furthermore, by providing a partition plate and a water return prevention plate between the water supply port and the concentrated water blow port, mixing of the concentrated water in the upper part of the steam water separator and the supplied water is prevented.

To prevent the water level inside the steam water separator from rising during water supply, the concentrated canned water in the boiler can be blown out.

The effect is that highly dry steam can be stably supplied.

(Example) The present invention will be described in detail below with reference to one drawing. Figure 1 schematically shows a small-capacity boiler, in which a pair of upper and lower annular upper headers 3 and a lower header 4 are arranged, and a large number of water pipes 5, 5 are provided between the upper and lower headers 3 and 4. ... are connected. The steam separator 2 is connected to the boiler main body 1 through a steam communication pipe 6 and a downcomer pipe 7. Figure 2 is the first
This is an enlarged view of a part of the diagram, showing that a water supply port 8 is provided at the bottom of the steam water separator 2, a concentrated water blow port 9 is provided at the top of the steam water separator 2, and the water supply port 8 and the concentrated water blow port 9 are connected to each other. Circular partition plates 10 and square water circulation prevention plates 11 are provided at several locations in between.

The shape of the partition plate 10 may be such that a small circular hole is formed in the center of a circular plate to provide an escape port for deaerated air.

Next, to explain the operation of the steam water separator 2 shown in FIG. 1, water is supplied to the boiler from the water supply port 8 at the bottom of the steam water separator 2.
Inside the steam-water separator 2, it mixes with the circulating water at the bottom of the partition plate 10 and becomes high-temperature water.

It is supplied to the boiler main body via the downcomer pipe 7.

At this time, since the supplied water immediately becomes high temperature water, the anticorrosion effect of chemicals can be obtained. Also, by installing the partition plate 10 and the water circulation prevention plate 11, the concentrated water above the partition plate 10 is prevented from mixing with the supplied water, and the water level inside the steam water separator 2 is prevented from rising when water is supplied.

Concentrated canned water in the boiler can be blown out, and highly dry steam can be stably supplied.

(Effects of the Invention) Next, one aspect of the present invention will be described in detail. This steam/water separator is provided with a water supply port and a concentrated water blow port.

Because a water prevention plate is formed 7 times in the middle of the partition plate,
Maximum anti-corrosion effect with chemicals can be obtained.

Furthermore, the effects of blowing concentrated water and supplying highly dry steam can be obtained.
