Product Description
The Sanghi Acetylene Generator is of an advanced design, incorporating several features not ordinarily found in other generators.
The Sanghi Acetylene generator is a fully automatic plant. Pneumatically controlled valves and highly sensitive sensors, integral with the temperature control instruments, perform all operations. These in turn open the water inlet valve or residue drain valve etc. Two hydraulic pumps help to open and close the supply of calcium carbide, which is fed into the generator by screw feed conveyors.
The screw feed mechanism and the agitators are operated by flameproof motors and fittings. The entire operation is perfectly synchronized to give maximum efficiency and simplicity in operation. Any failure, whether it is of power supply, water or air is signaled visually and also audibly when an alarm bell rings to alert the operator.
Only flame proof lights and electrical fittings according to IS 214868 group II or BSS-229 may be used in an acetylene plant building. Acetylene cylinder must be of specification IS 7312:1974 or ICC 8.
Instrument Air Compressor
A flameproof motor with a buffer tank drives the instrument air compressor
Chemical Purifier
This consists of two layers of regenerative chemicals, which remove additional impurities. The purifying agent may be reactivated for re-use by the atmosphere air. For continuous operation one extra charge of chemicals can be kept in open wooden trolley.
Water Scrubber
The equipment is installed between the chemical purifier and the high-pressure compressor which helps to remove additional impurities from the gas if any.
Acetylene Compressor
For filling of the cylinders an I.R. make reciprocating, oil lubricated, multi stage, water submerged compressor with intercoolers, safety relief valve for each stage, driven by a 15 H.P. Flame proof motor confirming to IS 2148-68 Gr. II.B is provided.
No Loss - Carbide charge
No gas is lost or wasted while charging the carbide because that section is completely sealed off from the generator by a high pressure hydraulically operated valve. All the above controls are automatic and require no attention from the operator. There is a further safety device, in terms of an alarm bell, which will ring continuously till the fault is corrected.
High Pressure Drier
This consists of a battery of three high pressure vessels. The first is filled with metal filler, while the second and third are filled with anhydrous calcium chloride. It is very important that the high pressure drier is fully filled up with calcium chloride, as any voids in high pressure area are against the required safety.
Filling Manifold
This consists of a battery of 60 filling connections to connect to the gas cylinders. Non return valves are provided in various sections of the pipeline to the filling manifold. These non return valves are extremely important for the safe operation of the plant and should be periodically cleaned to remove rust and scales, iron cause fire. The cylinder filling pig tails flexible hose pipes should also be periodically cleaned to ensure that they do not burst during filling operation, if they do burst a fire would ensure due to sudden discharge of Acetylene.
High Pressure Control
If all the gas generated cannot be drawn in by the compressor and passed on to the filling manifold, either due to low capacity of the compressor or fast generations, gas pressure will gradually build in the generator. When the gas pressure reaches a predetermined level about 0.5 kg cm2 carbide charging will be cut off automatically and further generation of gas is stopped.
There is no expensive gasholder with the Sanghi Acetylene Generator. This item alone will reduce the investment on such a plant. Further, as the gas generated is always at a positive pressure, the pumping cost is also reduced. Since the generator is constantly at a positive pressure, once the plant has been purged with nitrogen no air enter the system, and it is this feature which makes Sanghi Plant inherently very safe.
