Vacuum Feed Gas Chlorinators — System Diagram
Vacuum Feed Gas Chlorinators

Principle of Operation

Motive Water (water at high pressure) passes through the Injector to produce vacuum. This vacuum extends upto Automatic Vacuum Regulator (AVR). The chlorine gas supplied (from Tonners / Cylinders or Chlorine Evaporators) under pressure is reduced to a lower pressure by Pressure Reducing Valve (PRV) and to a constant vacuum at the AVR. The gas under vacuum passes through a Gas Flowmeter or Rotameter and Flow Control Valve (FCV). A Differential Pressure Regulator (DPR) is provided for Chlorinators above Kgs/hr capacity, to control the pressure drop across the Flow meter and also to ensure accurate and steady flow of gas. The chlorine gas then gets mixed with the water at the injector and is then discharged to the point of application. Safety Valves like Emergency Check Valve, Emergency Drain Valve, Pressure Relief Valve and Vacuum Relief Valve are provided in this System to make it safe for both Operating Personnel and Equipment's longevity.

System Components
01

Automatic Vacuum Regulator

  • Normally closed and opens only when there is vacuum, thus regulating the flow of chlorine gas in a controlled manner.
  • Exclusive design ensures minimal risk of handling chlorine gas under pressure.
02

Flow Meter

  • Indicates directly the flow of Chlorine gas in terms of Grams/ Kilograms/ Pounds consumed per hour.
  • Made of Borosilicate glass and calibrated for 0.1, 0.2, 0.5, 1, 2, 3, 5, 6 10, 15, 20, 25, 30, 40, 50, 75, 90, 110,150, 200, 250 kgs/hr.
  • Accuracy is ± 4% of indicated flow. Flow can be adjusted by a specially designed Flow Control Valve allied with the Flow meter.
03

Safety Valves

  • The system is provided with Pressure Relief Valve, Vacuum Relief Valve, Check Valve and Emergency Drain Relief Valve.
  • Ensures safety at all critical moments to both Men and Machinery
04

Injector

  • Comes in Fixed-throat and Variable-throat types.
  • Variable orifices can be provided along with throttle valve for capacities above 50 Kgs/hr thereby reducing water consumption to a minimum.
  • Made of PVC-FRP/ Cast Iron Rubber Lined/ Mild Steel Rubberlined.
  • This is a Venturi Principle Injectors Where in Motive Water at Higher Pressure is Used to Create Vacuum to Suck and Mix Desired Chlorine Gas Uniformly and Send to Point of Application.
  • Ensures continuous and constant quantity of chlorine solution by using a packed Absorption Tower.
  • Capacity normally ranges from 200 Gms/hr to 40 Kgs/hr of Chlorine. (Higher capacities can also be provided on request)
  • Simple design, very easy to operate and maintain.
  • Fewer spares, less operating costs.

Gravity Feed Gas Chlorinators

Principle of Operation

Chlorine Gas from Cylinders/Tonners at regulated pressure passes through a Flow Control Valve, Rotameter/Flowmeter, Moisture-Trap and Check Valve to a Packed Absorption Tower where it gets uniformly mixed with the incoming water. The chlorine solution is then discharged to the point of application [normally discharged into a sump or reservoir at an elevation below the Absorption Tower only]. The Flow meter directly indicates the amount of chlorine consumed. It is very important that the required water flow to the Absorption Tower, should be constant and continuous at the time of operation for safety reasons.

 

System Components
01

Flow Meter

Indicates directly the flow of Chlorine gas in terms of Grams/ Kilograms/ Pounds consumed per hour.
  • Made of Borosilicate glass and calibrated for 0.2, 0.5, 1, 2, 3, 5, 6 ,10, 15, 20, 25, 30, 40 kgs/hr of chlorine gas.
  • Accuracy is ± 4% of indicated flow.
  • Flow can be adjusted by a specially designed Flow Control Valve allied with the Flowmeter.
02

Absorption Tower

Comes in both Co-Current and Counter Current Types. Design:3000 parts of chlorine dissolves in one litre of water. Our design consideration is dissolution of 1500 parts of Chlorine in one litre of water.
  • Chlorine gas is released inside the packed [PVC/PP Rashig rings] Absorption Tower with high velocity with 360°+ 90° turn ensuring a uniform and complete mixing.
  • A "Compensating-Head" is provided to avoid Back-surge during pressure drop of Chlorine gas.
