The chlorinator is an important component of chlorination equipment and is commonly used in mechanical sewage treatment. Its role is to safely, accurately, and efficiently transport chlorine from chlorine bottles to the chlorination point. The liquid chlorine evaporates into chlorine gas, which undergoes pressure reduction, filtration, measurement, and full mixing with water by the chlorinator before being added to the filling port. There are various types of chlorinators that can be selected based on the amount of chlorination and operational requirements. This paper primarily introduces the basic working principle and structure of the chlorinator for swimming pools.
Point 1: Function of the Pool Chlorinator
Function: Transporting chlorine from the chlorine bottle to the chlorination point
Composition: Separator, rotor flow machine, control network, etc.
Classification: Manual and automatic chlorinator
Point 2: How the Pool Chlorinator Works
- The chlorinator is a liquid chlorine dosing equipment. Liquid chlorine evaporates into chlorine gas, which undergoes pressure reduction, filtration, measurement, and full mixing with water by the chlorinator before being added to the filling port.
- The chlorinator is composed of a separator (filter), a rotor flow machine, a control network, a pressure gauge, and a water injector. Commonly used chlorinators include rotor chlorinators, vacuum chlorinators, follow-up chlorinators, and so on.
- The body of the chlorinator is equipped with a black manual valve, a vacuum gauge, and a glass gas flow meter. During production, the operator can adjust the chlorination amount according to production requirements when the automatic controller is not used.
- The gas flow meter provides a visual indication of the gas, allowing the operator to know the instantaneous dosage through the number engraved on its outer wall. The vacuum meter provides a visual display of the vacuum value generated by the water injector, helping the operator analyze the normal operation of the entire production.
- In normal production, the reading of the vacuum meter is consistent. The value will gradually decrease as the dosage increases, and once the equilibrium point is reached, it stops falling.
Point 3: Structure of the Pool Chlorinator
Cabinet: The chlorination cabinet is factory-assembled, pre-installed with piping, wiring, and taken over as a shipping unit.
Manual flow control valve: The manual flow valve is adjusted from the front of the cabinet and can be used to manually adjust the required flow rate when the automatic valve is not in use (the automatic valve is closed).
Automatic valve (automatic system only): The opening or closing of the automatic valve is in response to the signal from the controller. The automatic valve provides an electrical signal of the valve position for displaying and recording the gas flow.
Gas flowmeter: Gas flow meters provide a visual indication of the gas flow rate. The flow meters can be set manually or automatically. The capacity range of each flow meter is marked on the glass tube.
Vacuum gauge: The vacuum meter provides a visual indication of the vacuum value produced by the water injector, and the vacuum meter is dual, indicating mercury inches and kilopascals. The watch has been sealed in the factory with a protective film to prevent gas corrosion and should never be opened.
Water injector/check valve: The water injector/check valve is operated with sufficient pressure and flow of water to produce the vacuum required to operate the vacuum regulator. In most cases, a booster pump is required to supply pressure water. The water ejector/check valve can be mounted in a floor cabinet, and the gas intake is connected to the vacuum tube.
