Building a General-Purpose Oxygen Generator

Oxygen is an essential element for various applications, including small torches and household chores. Building a general-purpose oxygen generator can provide a convenient source of oxygen without the need for expensive components. In this article, we will guide you through the process of building your own oxygen generator, step by step.

1. Introduction

Before delving into the details of constructing an oxygen generator, it is crucial to understand the significance and potential uses of such a device. Oxygen generators can be used in various scenarios, such as welding, soldering, and even providing oxygen supply for medical purposes. By having a general-purpose oxygen generator, you can have a readily available source of oxygen for your specific needs.

2. Building a General-Purpose Oxygen Generator

2.1. Gathering the Required Materials

To begin with, you will need the following materials:

• PVC pipe (approximately 4 inches in diameter and 10 inches long)
• Transparent plastic box with an airtight cover
• PVC coupling and a thin transparent hose
• PVC ball valve
• PVC swamp cooler float
• Two 10-gauge insulated copper wires (red and black)
• Two 10-inch stainless steel screws
• Pair of nuts for attaching screws to copper wires
• Small transformer
• 3M 600 volt diode bridge

Make sure you have all these materials before proceeding with the assembly.

2.2. Assembling the Oxygen-Producing Cell

The first step is to attach the PVC pipe adapter to one end of the PVC pipe, ensuring a perfect seal without any leaks. Strip the insulation off the red wire to create an eyelet and attach it to one end of the stainless steel screw using a pair of nuts. Apply waterproof sealant to cover the copper wire and prevent it from touching the electrolyte. Fasten the screw inside the PVC tube with a plastic strip, allowing the water inside the pipe to be pushed down by the oxygen produced.

Next, attach the PVC tube adapter to the lid of the box using rubber gaskets to ensure a secure and sealed connection. The oxygen generating cell should be suspended about an inch away from the bottom of the box, providing enough space for the oxygen to accumulate.

2.3. Connecting the Electrical Components

The electrical connection involves using a small transformer and a diode bridge as the power supply. Follow the diagram provided to make the necessary connections. The transformer's secondary winding should go to the diode bridge's AC input, while the positive terminal of the bridge connects to the red wire of the oxygen generating cell and the negative terminal connects to the black wire from the hydrogen generating screw. The transformer's primary winding connects to a regular outlet (127 or 220 volts AC).

2.4. Adding the Sodium Hydroxide Solution

To initiate the oxygen generation process, dissolve about one ounce of sodium hydroxide (NaOH) in a large glass of water and pour it into the plastic box. Ensure the box is filled to the necessary level by opening the valve filling the float. The water level should cover both stainless steel screws, allowing the oxygen and hydrogen production to begin.

2.5. Controlling the Oxygen and Hydrogen Output

Regulating the oxygen and hydrogen output is essential for safety and efficient operation. By opening the oxygen outlet valve, air can escape from the oxygen generating cell, and oxygen will flow into the room or area where it is needed. The hydrogen generated during the process needs to be released to the outdoor air to avoid any potential hazards. This can be achieved by installing a one-inch diameter PVC pipe that extends about six feet outside the house.

Keep in mind that the water level in the box must be maintained, covering both stainless steel screws. If the water level drops below a certain point, the reaction will stop, and the oxygen production will cease. By adjusting the oxygen outlet valve and monitoring the water level, you can have a continuous supply of oxygen.

3. Safety Considerations

When working with oxygen and hydrogen, it is crucial to prioritize safety. Both gases can be highly flammable and pose a risk of explosions or fires if not handled properly. Here are some safety considerations to keep in mind:

3.1. Handling Oxygen and Hydrogen

Oxygen supports combustion, making it crucial to avoid exposing it to flammable materials or open flames. Additionally, hydrogen gas is highly flammable and can also lead to explosions or fires. When handling these gases, ensure you are in a well-ventilated area and away from any potential sources of ignition.

3.2. Preventing Fires and Explosions

To prevent fires and explosions, it is essential to maintain proper water levels and ensure the stainless steel screws are always covered by water. This prevents hydrogen buildup and keeps the gases at safe levels. Additionally, ensure all valves are properly sealed, and there are no leaks in the system.

4. Conclusion

Building a general-purpose oxygen generator can provide a convenient and cost-effective solution for various oxygen-dependent tasks. By following the step-by-step instructions outlined in this article, you can construct your own oxygen generator using readily available materials. However, always prioritize safety and take necessary precautions when working with oxygen and hydrogen gases.
