Sanghi - Acetylene Generators
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 & 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.
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 a further safety device, in terms of an alarm bell, which will ring continuously till the fault is corrected.
The Sanghi Acetylene Generator can be set to operate at any given temperature, regardless of the size of carbide used or the temperature of the cooling water. A Sensitive sensor actuates a pneumatic control that adds water into the generator tank when the temperature exceeds the set limit, thus maintaining a given standard temperature. This helps in the complete utilization of carbide, which is a very expensive raw material.
If all the gas generated cannot be drawn in by the compressor and passed on to the filling manifold, either due to the 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 in 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, it is this feature which makes “SANGHI” Plant inherently very safe.
