Injection quills are devices that are used to inject chemicals into the water system of a cooling tower. They are usually situated near the base of the tower and their purpose is to ensure that the chemicals are evenly distributed throughout the water in the tower.
Types of chemicals used in cooling towers are Scale inhibitors, Corrosion inhibitors, Biocides and pH adjusters.
Here will discuss Scale inhibitors and Corrosion inhibitors. Click here for Biocides and pH adjusters.
a. Scale inhibitors
Injection quills are used to inject scale inhibitors into cooling towers as a way to prevent mineral buildup on the heat transfer surfaces. Scale inhibitors work by altering the chemical properties of the water in the cooling tower, making it less likely for minerals to form and adhere to surfaces.
The quills are typically located near the base of the tower and are designed to ensure that the chemical solution is evenly distributed throughout the water in the tower. They have small holes or nozzles that allow for a controlled flow of the scale inhibitor solution into the water flow.
The scale inhibitor solution is injected into the water system of the cooling tower through the quills. As the water flows through the tower, it comes into contact with the scale inhibitor, which alters the chemical properties of the water, making it less likely for minerals to form and adhere to surfaces.
The quills can be adjusted to control the flow rate of the scale inhibitor solution, allowing for precise control of the dosing. The flow rate can be adjusted depending on the water conditions and the mineral content of the water. This can help to ensure that the appropriate amount of scale inhibitor is being added to the water, helping to prevent mineral buildup on the heat transfer surfaces.
In summary, Injection quills are used to inject scale inhibitors into cooling towers by introducing a controlled flow of scale inhibitor solution into the water system of the cooling tower through the quills, and by altering the chemical properties of the water, making it less likely for minerals to form and adhere to surfaces, and by adjusting the flow rate of the scale inhibitor solution to ensure the appropriate amount of scale inhibitor is being added to the water, helping to prevent mineral buildup on the heat transfer surfaces.
b. Corrosion inhibitors
Injection quills are used to inject corrosion inhibitors into cooling towers to prevent corrosion of the metal surfaces of the cooling tower and associated piping. Corrosion inhibitors work by altering the chemical properties of the water in the cooling tower, making it less aggressive to the metal surfaces.
The quills are typically located near the base of the tower and are designed to ensure that the chemical solution is evenly distributed throughout the water in the tower. They have small holes or nozzles that allow for a controlled flow of the corrosion inhibitor solution into the water flow.
The corrosion inhibitor solution is injected into the water system of the cooling tower through the quills. As the water flows through the tower, it comes into contact with the corrosion inhibitor, which alters the chemical properties of the water, making it less aggressive to the metal surfaces. This can help to protect the metal surfaces from rust and other forms of corrosion.
The quills can be adjusted to control the flow rate of the corrosion inhibitor solution, allowing for precise control of the dosing. The flow rate can be adjusted depending on the water conditions and the mineral content of the water. This can help to ensure that the appropriate amount of corrosion inhibitor is being added to the water, helping to prevent corrosion of the metal surfaces of the cooling tower and associated piping.
In summary, Injection quills are used to inject corrosion inhibitors into cooling towers by introducing a controlled flow of corrosion inhibitor solution into the water system of the cooling tower through the quills, which alters the chemical properties of the water, making it less aggressive to the metal surfaces, protecting them from rust and other forms of corrosion, and by adjusting the flow rate of the corrosion inhibitor solution to ensure the appropriate amount of corrosion inhibitor is being added to the water, helping to prevent corrosion of the metal surfaces of the cooling tower and associated piping.
