Abstract

The present invention relates to a high-vacuum serial condenser system that can minimize a pressure drop of fluid in condensers by disposing straight pipes between the condensers and installing baffles at predetermined angles in the condensers.

First claim

The invention claimed is:

1. A high-vacuum serial condenser system comprising:
a first condenser including a shell that has one or more vapor inlets for supplying gas-state fluid to be condensed, a condensed liquid outlet for discharging condensed liquid to the outside, and one or more vapor outlets for discharging gas-state fluid, vapor supply pipes coupled to the one or more vapor inlets, and a condensed liquid discharge pipe coupled to the condensed liquid outlet;
a second condenser including a shell that has one or more vapor inlets for supplying gas-state fluid discharged from the one or more vapor outlets of the first condenser to be condensed, a condensed liquid outlet for discharging condensed liquid to the outside, and a vapor outlet for discharging the gas-state fluid to the outside, a condensed liquid discharge pipe coupled to the condensed liquid outlet, and
a vapor discharge pipe coupled to the vapor outlet; and
vapor delivery pipes for delivering and supplying the gas-state fluid discharged from the one or more vapor outlets of the first condenser to the second condenser,
wherein the one or more vapor outlets of the first condenser and the one or more vapor inlets of the second condenser face each other; the vapor inlets and the vapor outlets of the first condenser are arranged at a right angle relative to a longitudinal center axis of the first condenser, and the vapor inlets and the vapor outlets of the second condenser are arranged at a right angle relative to a longitudinal center axis of the second condenser; and tubes for delivering refrigerants and baffles for making flow in a specific pattern are disposed in each of the first and second condensers at 45° between the one or more vapor inlets of the first condenser and the one or more vapor outlets of the first condenser and at 45° between the one or more vapor inlets of the second condenser and the vapor outlet of the second condenser,
wherein the vapor delivery pipes between the one or more vapor outlets of the first condenser and the one or more vapor inlets of the second condenser are straight pipes, and
wherein pressure of the fluid in the condensers is 3 to 30 torr.

2. The system of claim 1 , wherein the baffles are arranged at 45° to block the fluid supplied through the one or more vapor inlets of the first condenser and the second condenser so that the fluid flows opposite to the vapor outlets.

3. The system of claim 1 , wherein the first condenser includes two or more vapor inlets, and each of the vapor inlets of the first condenser is formed per 1 to 2 m of a length of the first condenser.

4. The system of claim 1 , wherein the first condenser includes two or more vapor outlets, and each of the vapor outlets of the first condenser is formed per 1 to 2 m of a length of the first condenser.

5. The system of claim 1 , wherein the first condenser and the second condenser are cross flow condensers.
