GAS SULFONATOR
SERIES SDM-5
The SUPERIOR™ Series SDM-2/5 Gas Sulfonator is a state-of-the-art, vacuum-operated, solution feed type which mounts directly on a sulfur dioxide valve. The Sulfonator is mounted onto the sulfur dioxide valve of a cylinder, wall manifold, or ton container adaptor using a very heavy-duty, positive yoke clamp connection. A sulfur dioxide gas flow meter indicates the amount of sulfur dioxide being fed. Sulfur dioxide flow rate is manually adjusted, and the design permits easy addition of a number of automatic flow rate control devices. A high-efficiency, water-operated ejector produces the vacuum necessary to operate the system. The ejector assembly contains a back-flow check valve system to prevent pressurized water from entering the Sulfonator. A spring-opposed diaphragm vacuum regulator controls the sulfur dioxide gas flow rate and also acts as the safety shut-off valve.
SDM-5 TYPICAL INSTALLATION
FEATURES
The SUPERIOR™ Series SDM-2/5 represents the most modern design technology coupled with the very best materials available to create an outstanding, user-friendly piece of equipment. It is designed with user safety as a primary concern.
-
A new ultra-thick fluoroplastic yoke coating gives SUPERIOR™ unmatched protection. It will not crack, peel, or chip. Sulfur dioxide will not diffuse through it to cause coating bubbling and peeling.
-
All machined parts are high-impact PVC plastic, designed for strength, corrosion resistance, and sulfur dioxide resistance.
-
The rate valve "Seat" is pure fluoroplastic and will not swell, stick, or become brittle with age or exposure to liquid sulfur dioxide.
-
All external bolts and nuts are Titanium for complete corrosion resistance — a SUPERIOR™ exclusive. There are no stainless steel or Monel nuts and bolts to corrode and freeze up in the presence of moist sulfur dioxide gas.
-
Extra heavy-duty outlet threads on the ejector diffuser prevent breakage from over-tightening or “bumping” of the ejector assembly.
-
(Number was missing — included for proper sequence)
-
Easier to service and perform routine maintenance, with standard-size wrench lugs provided on all screwed-together ejector parts.
-
All vacuum fitting holes are heavily reinforced to prevent the possibility of cracking from over-tightening fittings.
-
The "dual-pressure" check valve is standard on all SUPERIOR™ gas Sulfonators. Proven high back-pressure unitized check valve design protects against sudden surges up to 300 PSIG, while a spring-loaded diaphragm check provides positive shutoff even when there is no back-pressure to force the seat closed.
-
Fewer parts, combined with SUPERIOR™ materials and a SUPERIOR™ design, give you a SUPERIOR™ Gas Sulfonator.
SDM-5 FLOW DIAGRAM
SYSTEM OPERATION
The vacuum regulator is securely clamped onto the sulfur dioxide cylinder valve. Water under pressure flows through the ejector at high velocity, which causes a strong vacuum to be created. This opens the check valves in the ejector assembly and transmits a vacuum signal through the remote meter tube/rate valve panel and back to the vacuum regulator. When the vacuum reaches a pre-set level, the diaphragm in the regulator moves to open the sulfur dioxide inlet safety valve, permitting gas to flow from the sulfur dioxide cylinder. The spring-opposed diaphragm and inlet valve regulate the vacuum at this point.
Sulfur dioxide gas passes through the remote flow meter panel and rate control valve to the ejector. The gas mixes with the ejector water and is discharged through the diffuser into the treated water.
FLOW METER CAPACITIES
A dual English/Metric scale variable area flow metering tube is provided with a maximum capacity of 250 pounds per 24 hours – 5 kg/hr (Model SDM-2) or 500 pounds per 24 hours – 10 kg/hr (Model SDM-5). All metering tubes are interchangeable and may be changed in the field without special tools.
MODULAR DESIGN
SUPERIOR™ Gas Sulfonators have been designed to give maximum flexibility in system installation. The vacuum regulator and metering tube panel are close-coupled and mounted onto the sulfur dioxide cylinder as a single assembly. The ejector can be located wherever plumbing and/or hydraulic conditions make it most desirable. Modular design also makes it easy and inexpensive to expand or upgrade the system. The metering tube panel may be detached from the vacuum regulator at any time, in just a few minutes, if future requirements or safety dictate a remote metering application, or multiple-point chlorination is desired.
MATERIALS OF CONSTRUCTION
One of SUPERIOR™'s major competitive advantages is the use of the finest, strongest, and most durable materials available. Extensive use of fluoroplastics and fiberglass-reinforced thermoplastics allows SUPERIOR™ Gas Sulfonators to withstand attack by sulfur dioxide in any form and to give the longest operational life. Many parts are guaranteed for the life of the equipment against sulfur dioxide damage.
SPECIFICATIONS
The Sulfonator shall be SUPERIOR™ MODEL SDM-2/5, manufactured by Chemical Injection Technologies, Inc., Ft. Pierce, Florida, and shall have a maximum capacity of ___ pounds per day /gr/hr of sulfur dioxide feed and shall be equipped with a sulfur dioxide flow meter of ___ pounds per day /gr/hr. The Sulfonator shall consist of a close-coupled vacuum regulator/flow meter, and ejector/check valve. Each of these assemblies shall be capable of being individually located wherever safety and/or operator convenience dictates. The vacuum regulator/flow meter assembly shall be capable of being separated into independent vacuum regulator and metering panel assemblies at any time for remote metering or multiple point applications. The vacuum regulator shall mount directly on the cylinder valve by means of a positive yoke-type clamp having an integral tightening screw with slide bar handle. No wrenches or other tools shall be required to mount or dismount the vacuum regulator from the cylinder. The cylinder valve/Sulfonator inlet adaptor shall be constructed of corrosion-proof fluoroplastic material which shall be inert to the effects of wet, dry, or liquid sulfur dioxide. The inlet safety shut-off/vacuum regulating valve shall be of capsulated design, easily removable as a unit from the outlet side of the yoke. A ceramic filter shall be installed in the vacuum regulator inlet and shall be capable of removing impurities greater than 25 microns. A pressure relief valve shall be incorporated into the vacuum regulator to prevent pressure from building up in the system. All external screws and nuts shall be made of Titanium to prevent corrosion. The vacuum regulator/flow meter bodies shall be constructed of high-impact PVC plastic material and shall incorporate a flow rate control valve made of fluoroplastic material which is inert to the corrosive effects of sulfur dioxide. The rate valve metering tip shall be constructed of metal which is completely impervious to the effects of wet, dry, or liquid sulfur dioxide attack. Design shall provide for full closing of the rate valve without engaging the control surfaces, to prevent damage. Vacuum shall be created by a fixed-throat venturi/ejector system connected directly to the sulfur dioxide solution diffuser. A dual high-pressure/low-pressure check valve system shall prevent water from entering the gas system. The ejector assembly shall be capable of withstanding water pressure up to 300 PSIG (20.7 Bars). A universal-type sulfur dioxide solution diffuser shall be provided, which shall allow close-coupling of the ejector to a water main, use of flexible solution hose, or rigid solution pipe without the use of special adaptors.
