CONSTRUCTION OF THE DEVICE:
The device is made to separate pollutants by chemical scrubbing. It consists of:
A main body
It is the cuboidal shell of the device where the cleaning process takes place. In the prototype it is 20in tall, 6in long and 6in wide. The body is made up of stainless steel for its property to resist corrosion and having high melting point. This is the part where various assembly of the device is fixed and also various chemical reaction will take place.

These reactions are all exothermic in nature and will produce lot of heat. Thus, device is made up of a conducting material. There is 6 inches pipe with the cross-section of 2 inches diameter welded on it as main protrusion to connect the connection tube and used as inlet of exhaust gases.
Connection tube
Connection tubes are responsible for transfer of exhaust gases to inlet of the main body. These gases have a very high temperature of about 100? to 150? and also have a high pressure.
Thus tubes are chosen so they can endure high temperature and pressure. For this experiment, vulcanised rubber is chosen.
Saw-dust cleaner
It is actually a filter device, used to separate shoot particles, especially unburnt carbon. It is made up of cylindrical vessel, truncated at both ends and filled with saw dust. The saw dust act as fine particles which collides with the shoot particles and adsorp them. The device is made up of a thick material, which will have ability to withstand pressure created due to semi-plugging the exhaust gas.

Chemical chamber
The system uses a chemical wet scrubbing process to clean the pollutant particles. For this purpose, a chamber is made in the main box. It has upper and lower edge sealed by the metal sieve which as small holes. This make the chamber gas permeable and also have capacity to hold the packing material. Packing material used is bitumen coal.
Distribution System
This system is responsible for the uniform distribution of the scrubbing material over the chamber. It is made up of a bucket to be used as overhead tank which can be replaced by a normal bucket with a suitable motor. There is rubber pipe sealed at one end. The other end of the pipe is connected to the tap attached to the bucket. This pipe is pierced with number of holes. When scrubbing material flows in the pipe, it spills out of these holes. The pipe is arranged such that it will reach most of the places and thus chemical is distributed.

DESCRIPTION:
The exhaust gases is made to pass through a saw dust cleaner with the help of connection tubes before they go into the setup device. In the device, an exhaust fan is present just below the entry point. Its purpose is to create forced draught in the device so that all the gases move upwards. In the middle section of the device, there present bituminous coal which acts as absorber to absorb various pollutants particles. A continuous shower of aq. NaOH solution is poured on the bituminous coal. Thus, various reactions happens converting the oxides of carbon, nitrogen, sulphur into their respective salts and water. Most of the water gets vaporised due to the large heat produced during the reaction, rest of the water containing all these salts flow from the bottom of the device where it is collected in order to perform confirmatory tests on it in chemistry lab to check presence of these salts. The sample thus collected after using 2 L of NaOH was about 150 mL-200 mL.
