Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a condenser, and provides a condenser that can efficiently condense water vapor contained in a suction airflow.

An embodiment of the present invention will be described below based on the drawings.

1 is an inner cylinder whose upper end is closed, and 2 is an outer cylinder whose upper and lower ends are both closed, and these inner cylinder 1 and outer cylinder 2 constitute a main container 3 having a double structure.

Reference numeral 4 denotes a solid filler layer provided in the inner cylinder 1, in which a solid material 5 made of polypropylene of a special shape with a very large porosity is placed between wire meshes 6, 6 provided at an interval in the axial direction of the inner cylinder. It is made by filling.

The vertical upper space 7 of the solid filler layer 4 communicates with a suction device connection port 8 that connects to a suction device such as a vacuum pump, and inside this upper space 7 are numerous nozzles that spout cooling water. 9 is provided.

The nozzles 9 are attached to a distribution pipe 10 fixed to the earthen wall of the inner cylinder 1, and are arranged in large numbers so that cooling water can be evenly sprayed over the entire vertical upper surface of the solid filler layer 4.

11 is a water supply pipe communicating with the distribution pipe 10. 9 is outer cylinder 2
A cooling water injection nozzle is disposed in the annular space 12 between the inner cylinder 1 and the inner cylinder 1, and is provided in the distribution pipe 10 communicating with the water supply pipe 11.

The annular space 12 is located vertically below the filler layer 4 and the inner cylinder 1
The outer cylinder 2 is provided with a water vapor inlet 13 that communicates with the inside and opens in the tangential direction of the outer cylinder 2 at the vertically upper part of the annular space 12 .

Further, the bottom of the outer cylinder 2 constitutes a condensate storage section 14,
A pump 15 for discharging the water in the storage section 14 to the outside of the main container 3 is installed within the storage section 14 .

16 is a water intake port of this pump 15, and 17 is a drain port.

18 is a pump drive motor installed outside the main container 3;
Reference numeral 9 denotes a seal portion provided on the main body container 3 at the penetrating portion of the drive shaft 20.

Next, the operation will be described. By operating the suction device connected to the suction device connection port 8, water vapor flows in from the steam inflow port 13 together with air.

Since the water vapor inlet 13 is provided in the tangential direction of the outer cylinder 2, the water vapor and air descend while traveling within the annular space 12, uniformly flow into the inner cylinder 1 from around the inner cylinder 1, and solidify the water vapor and air. The substance rises within the filling material layer 4 toward the suction device connection port 8.

On the other hand, cooling water is injected from the nozzle 9, and while the cooling water flows down inside the solid filler layer 4, the water vapor exchanges heat with the cooling water and condenses.

In this condensation, the water vapor and cooling water pass through the solid filler layer 4 made of solid material 5 with a high porosity, so that a large contact area or contact time between the water vapor and the cooling water is obtained, and the water vapor is Can be condensed.

Then, the air containing the condensed water vapor is discharged from the suction machine connection port 8, and the condensate and cooling water flow down to the condensate storage section 14 at the bottom of the outer cylinder 2, and are discharged to the outside of the main container 3 by the pump 15. be done.

As explained above, in the present invention, water vapor uniformly flows into the solid filler layer and exchanges heat with cooling water, so that water vapor can be efficiently condensed.
