Chlorine distributors are crucial devices in swimming pool water treatment systems for accurately dispensing chlorine disinfectants, effectively controlling microorganisms in the water. Submerged (submersible) chlorine distributors and floating chlorine distributors are the two most commonly used types. These two chlorine dispensers differ in their structure and operational principles. The article provides a detailed exposition of the distinctions between submerged and floating chlorine distributors, aiding in a better understanding and appropriate selection of products based on specific needs.
Working Principles of Submerged Chlorine Distributor
A submerged chlorine distributor is typically connected to a chlorine gas or chlorine compound supply system. Chlorine is usually supplied as compressed gas, regulated by a valve before entering the distributor. In systems using chlorine tablets, solid chlorine is placed in a dedicated chlorination box and transported to the submerged chlorine distributor by a regulator. Water inside the submerged chlorine distributor is divided into two parts, flowing into each distribution pipe separately. The water flow in each distribution pipe can be controlled by adjusting the diversion valve. Flow rates in each distribution pipe are controlled by instruments or regulating valves, ensuring stable flow. By adjusting the number and arrangement of distribution pipes, the distribution of chlorine ions in the water can be more evenly balanced, ensuring compliance with specified quality standards.
Working Principles of Floating Chlorine dispensers
A floating chlorine distributor typically contains chlorine tablets or chlorine compound particles. Chlorine slowly dissolves in the water, releasing chlorine gas. The floating chlorine distributor is designed to be suspended on the water surface, releasing chlorine gas through openings on the distributor, aided by the movement and fluctuations of the water. Because floating chlorine distributors can move freely in the water, they can release chlorine gas from various locations in the pool. Chlorine in the distributor will be depleted after some time, necessitating periodic checks and the addition of new chlorine particles.
Comparative Analysis of Submerged and Floating Chlorine Distributors
Applicability
Submerged chlorine distributors are generally used in large water treatment systems like municipal water treatment plants and large swimming pools, designed to handle high water capacities.
Floating chlorine distributors are mainly used in small-scale water treatment facilities such as swimming pools and aquariums due to their easy placement in small water environments and adjustability.
Stability in Use
Submerged chlorine distributors are installed on the main supply pipes, effectively controlling chlorine concentration in the outgoing water by adjusting flow rates and chlorine ratios.
Floating chlorine distributors, being small devices installed in the water, can be influenced by floating devices, leading to unstable chlorine gas release. However, with regular maintenance, their normal operation can be ensured.
Environmental Impact
Submerged chlorine distributors, when dissolved, generate chlorine-containing gas. While chlorine is effective for water disinfection, excessive chlorine can adversely affect the surrounding environment and personnel. Design considerations for submerged chlorine distributors often include exhaust control to mitigate environmental impact.
Compared to gaseous chlorine, the diffusion of chlorine tablets in floating chlorine distributors is relatively easy to control. This helps reduce potential adverse effects on the surrounding environment, especially in small enclosed spaces such as swimming pool areas.
In summary, submerged and floating chlorine distributors differ significantly in structure and operational principles. Submerged chlorine distributors are stable and reliable devices for large-scale water purification, while floating chlorine distributors offer flexibility and convenience for small-scale water treatment projects. The correct selection of a chlorine distributor depends on specific application requirements. This article introduces floating chlorine distributors and, based on individual circumstances, encourages a rational choice to ensure the normal operation of water treatment systems and achieve desired water quality control and disinfection effects.
