3. PREAMBLE TO THE DESCRIPTION :
The following specification particularly describes the invention and the manner in which it is to be performed.

A System and Method for Reducing the Discharge Temperature and Thereby Cooling the Hot Compressed
Air through energy conservation.
Field of Invention:
The present invention relates to an arrangement to reduce the discharge temperature of the compressed air and thereby reducing energy consumption for given volume of compressed air for given pressure. More particularly it relates to the system and method for reducing the discharge temperature and thereby cooling the hot compressed air through conservation.
Prior Art:
Compressed air from the compressor is very hot and contains of the moisture. Its temperature is about 140°C to 150°C. It may pose a fire hazard to down stream equipment connected to the hot air outlet of the compressor. Hence it becomes necessary to reduce the temperature of the hot compressed air for further application. Basically for this purpose aftercoolers are used.
Aftercoolers are heat exchangers for cooling the discharge from the compressor. They use either air or water and are an effective means of removing moisture from compressed air. Aftercoolers control the amount of water vapor in a compressed air system by condension the water vapor into liquid form. In a distribution or process manufacturing system, liquid water can cause significant danger to the equipment that uses compressed air. An aftercooler is necessary to ensure the proper functioning of pneumatic or air handling devices that are part of process manufacturing systems.
Aftercoolers can use either air cooled or water cooled mechanisms. An air cooled heat exchanger uses ambient air to cool hot compressed air. An air cooled heat exchanger use a motor-driven fan to force the ambient air over the cooler, removing the heat from the compressed air. Water cooled aftercoolers use water for removing heat from the hot compressed air.

In the aforementioned methods, separate equipment are required for air compressor, each consuming a finite amount of energy apart from supervision, maintenance and running costs. Above two methods require regular maintenance as well as regular checkup. Also separate electricity is required to run cooling fan and water pump to maintain the temperature of air and also equipments are very costly and the maintenance cost of these cooling fan and water pumps is very high. The aforementioned drawback of high cost and maintenance makes it necessary to provide an arrangement which will provide cost effective means for reducing the temperature of the hot compressed air.
Objective of the Invention :
The primary objective of the present invention is to provide an arrangement which removes all the drawbacks associated the prior art systems for cooling the hot compressed air.
Another objective of the present invention is to provide the system and method for reducing the discharge temperature of the hot compressed air which is free from all deficiencies of the prior ail arrangements.
Yet another objective of the present invention is to provide cost effective and efficient system and method for reducing the discharge temperature of the hot compressed air.
Yet another objective of the present invention is to provide the system and method for reducing the discharge temperature of the hot compressed air which reduces the energy consumption for given volume of compressed air for given pressure.

Wherein water tank is provided with continuous flow of the cool water, said cool water lowers down temperature of the hot compressed air inside the stainless steel pipe, condenses the moisture and simultaneously at the same time hot water generated during cooling of the hot compressed air is drained from and outlet of the water tank.

Detailed description of the invention :
The above, and the other objects, features and advantages of invention will become apparent from following description read in conjunction with the accompanying drawings.
Meaning of the reference numbers used in the figure are as follow :
1 : Water tank
2 : Stainless steel pipe
3 : Air receiver tank
4 : Compressor unit
5 : Pit for collection condensed moisture
6 : Inlet of water tank

Now referring to figure 1 system for reducing the discharge temperature of the hot compressed air in accordance to present invention is shown. It mainly consists of water tank (1), stainless steel pipe (2) and air receiver tank (3).
The water tank (3) mainly consists of inlet (6) for allowing the entry of the cool water inside the tank and outlet (7) for allowing discharge of the hot water outside the water tank. The water tank is made up of bricks. It can be made by any other material as per need. Mostly water tank is situated under ground. All sides and base (8) of the water tank are made water proof.

The stainless steel pipe (2) is placed inside the water tank (1). It is situated above the base (8) at certain height in the tank (1). The steel pipe (2) is fitted in a water tank (1) in a continuous U shaped tubing fashion. This steel pipe (2) allows the passage of the hot compressed air from the compressor unit (4). The high pressure discharge pipe line (9) of the compressor unit (4) is connected to the stainless steel pipe (2) through flexible PVE pipe (10). The main purpose of providing flexible pipe is to absorb the vibration and avoid breakage of the stainless steel (2) during operation. The other end of the stainless steel pipe (2) is connected to air receiver tank (3).
The air receiver tank (3) consists of an inlet (12) to connect the other free end of the stainless steel pipe (2) through a PVC pipe (11). It also consist of an outlet (15) for providing the fresh cool compressed air and drain line {13) for separating the condensed moisture of the hot compressed air using drain valve (14) in a pit (5).
Working of the system:
Firstly the water tank is provided with the continuous flow of the cool water through the inlet to reduce the discharge temperature of the hot compressed air which flows through the stainless steel pipe. Then the hot compressed air at the temperature of 140°C is allotted to pass through the stainless steel pipe. At the same time the hot water generated during cooling of the hot air using cool water is continuously drained out through the outlet of file water tank. Compressed air passes on its way to the air receiver tank through the stainless steel pipe, because of the water cooling the compressed air at the temperature of 45° to 50°C and condenses the moisture. This moisture passes on to the receiver tank and is drained either manually or by drain valve through the drain line. Hence the fresh and pure cooler air at the temperature of 450 to 50°C is available at the outlet of the air receiver tank.
