Hello World,
Today i will like tell you all about my 4th year project which was on the topic of experimental analysis of an air washer.
In the recent sanario the peoples are slowly getting conscious about the beast(pollution) intended to destroy our beautiful sphere(earth). This pollution had drastically spread in our world drastically in few years. It is sad to say but we are only responsible for it. The careless burning of fossil fuels, heavy growth in industries and inventions without considering about the earth safety pushed of us into this undesirable situation.
But now the peoples are thinking about what they are doing and what they had done including the government which taken so many steps for the control on pollution. The scientist's also get conscious about their invention which will be in the favor the reducing pollution.
In India the refrigerants like R 22 is going to be banned in upcoming few years which is one of the major reason for the depletion of the ozone layer which causes global warming and some harmful skin disease's. These things created the requirement for the replacement of old cooling systems and introduction of the new inventions which are environment friendly.
My project was on the same concern me and my friends decided to try the project which can be the one of the substitute of the recent refrigeration system. On the suggestion of our professor we modified the air washer to not only work as an evaporative cooler but also can remove the sulphure dioxide from the air which is one of the gas responsible for green house effect.
In my project my team was using spray type air washer with the very simple design since it become easier to modify.
The spray type air washers consists of a chamber or casing containing a spray nozzle system, a sink for removing the spray water as it falls. And an eliminator section for the removal of moisture in the air. A pump recirculates water at the rate higher than the evaporation rate.
Intimate contact between the spray water and the air flow causes heat and mass transfer between the air and the water.
The air washer used in the industries has the basic use to clean air and control the properties of the air as per the requirement.
The air washer can perform two kinds of cooling:
1. Direct evaporative cooling
2.Indirect evaporative cooling
The direct evaporative cooling is done by the direct contact between sprayed water and the flowing air in the chamber.
Where the indirect evaporative cooling is done by providing heat exchanger at the front of air washer.
The syphon present in the heat exchanger is circulated by the cold water and the hot air is passed through the fins of the heat exchanger. Which causes heat exchange between air and water.
The indirect evaporative cooling was done in my project by the use of car radiator.
AIR WASHER SPECIFICATIONS
BLOWER
suction blower with 1HP, 3PHASE, 440 V and internal diameter 4 inch
NOZZLE SECTION
the nozzle section consist of:-
1. 4 elbow joints (0.5 inch bore)
2. 3 distributors (0.5 inch bore)
3. 10 vertical pipes (0.5 inch bore & 50 cm length)
4. 10 holes on vertical pipe each (1 mm bore)
5. 5 holes on horizontal pipe each (1 mm bore)
All the components in the nozzle section are made up of PVC material.
The body of the air washer was made up of the aluminium composite pannel.
Two layers of simple cellulose pad was use in the eliminator section to absorb the moisture in the air.
The picture above will give you the brief and real understanding of the project.
The analysis was done with the following aims:
1. circulating the water at normal temperature and analyzing the changes in the property of the air
2. circulating hot water through air washer and analyzing the change in the properties of air
3. circulating chilled water through air washer and analyzing the changes in properties of air
I am providing some videos of working of my project i hope you will like it.
please give reviews on my publish and don't forget to follow.
your reviews are precious to me and your following will motivate to share new views
thank you.
