Abstract

PROBLEM TO BE SOLVED: To remove steam from gas through a simple structure by arranging a spherical cooling member in a dust passing steam so that a steam flow collides against the cooling member at a relatively high speed. SOLUTION: Gas containing steam is brought into collision against a spherical body of lower temperature than the steam in order to condense the steam and to taking out the drain. A spherical cooling member 16 is disposed substantially in the center to a tubular duct member 10 while being supported by a supporting member 18. Gas containing steam enters into duct member 10 from the inlet end 12 and flows through a tubular guide 26 on the inlet side and the tapered open inner end thereof at a relatively high speed to collide against the spherical cooling member 16. Consequently, the steam is cooled and condensed and dropped, in the form of drain, into the duct member 10. The condensed water is taken out through a drain collection port 28. Temperature rise of the spherical cooling member 16 due to collision against steam is suppressed by means of cooling fins.

The steam-containing gas introduced from the inlet end of the conduit member strikes the cooling member at a relatively high speed from the inner end of the tapered opening of the tubular guide, and is cooled by the cooling member to condense the steam. . The gas dried by the condensation of the water vapor is guided to the outlet end of the conduit member through the inner end of the opening of the tubular guide on the outlet side of the conduit member, and is discharged to the outside.

The condensed water is taken out through a water recovery port formed in the conduit member.

【Example】

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The principle of the present invention is to condense water vapor by colliding a gas containing water vapor with a sphere having a temperature lower than the temperature of the water vapor, and to take out the water produced thereby.

To achieve this principle, the steam removal device according to the invention comprises a cylindrical conduit member 1 adapted to be connected to any conduit through which gas containing water vapor passes.
0. The conduit member has an inlet end 12 for receiving gas containing water vapor and an outlet end 14 for discharging treated gas.
And

A spherical cooling member 16 is located substantially at the center of the conduit member 10, and the cooling member 16 is supported at a predetermined position by support means 18. In the embodiment shown, the support means 18 is in the form of cooling fins 20 which contact the outer surface of the cooling member 16, which cooling fins 20 pass through the peripheral wall 10 </ b> A of the conduit member 10 in a sealed manner. 10 project outside. Therefore, the support means 18 also functions as a heat release means for releasing heat from the spherical cooling member 16 to the outside. Of course, the support means and the heat release means may be separate bodies.

Each of the inlet end 12 and the outlet end 14 of the conduit member has an open outer end 22 which is attached to the inner wall surface 10B of the conduit member 10 in a sealed state, and is directed toward the inside of the conduit member. A frusto-conical tubular guide member 26 is provided which is tapered and whose inner end 24 is open opposite the spherical cooling member 16. Tubular guide 2 at the entrance end
6 acts to impinge the received gas flow (indicated by arrow F) from the tapered inner end 24 onto the spherical cooling member 16 at a relatively high speed. Outlet end side tubular guide 26
Acts to prevent the condensed water droplets from being discharged from the outlet end 14 of the conduit member 10 as described later.

The tubular guide 26 on the inlet end side and the tubular guide 26 on the outlet end side have the same size and the same shape, and the present apparatus uses the center axis of the spherical cooling member 16 in the direction of the support means as an axis. It is almost symmetrical.

Near the outer end of each tubular guide 26,
A moisture recovery port 28 is formed in the peripheral wall 10A of the conduit member 10 so as to extend radially therethrough. The condensed water is taken out through these water recovery ports 28. Each of the water recovery ports 28 may be connected to a suction device (not shown) via a valve 28A.

In the illustrated embodiment, the spherical cooling member 16 is entirely covered with a moisturizing cloth 30. The moisturizing cloth 30 is further covered with a porous material 3 such as a protective wire mesh.
It is covered with 2.

Instead of the moisturizing cloth 30, the cooling member 16
May be covered with a hygroscopic material.

The cooling member 16 may be a solid sphere made of metal, or a hollow sphere made of metal and may be filled with a refrigerant or the like. Further, the cooling member 16 may be a solid sphere made of any material having high thermal conductivity that withstands the temperature of steam. If the cooling effect is not sufficient, the size of the solid sphere can be increased. When the diameter of the solid sphere becomes larger than the diameter of the conduit member 10, the conduit member 10 is provided with a bulge having a shape along the outer curved surface of the enlarged solid sphere.

The vapor-containing gas entering from the inlet end 12 of the conduit member 10 flows through the inlet side tubular guide 26 as shown by arrow F and is relatively high from the tapered open inner end 24 of the tubular guide 26. At a velocity, it collides with the spherical cooling member 16, thereby being cooled and condensed and falling as water droplets inside the conduit member 10 (indicated by reference numeral 34 in FIG. 1). The condensed water is taken out through the water recovery port 28.

The cooling member 16 is heated by the collision with water vapor and its temperature rises. However, the cooling fins 20 release heat to the outside of the conduit member 10 to suppress the rise in temperature. The gas dried by the condensation of the water vapor is discharged from the outlet end 22 of the conduit member 10 through the tapered open inner end 24 of the tubular guide 26 on the outlet side of the conduit member 10, and is sent to a desired site through a suitable conduit (not shown). Can be
