Smog tower: Delhi’s “smog season” is a couple of months away and, as preceding years have demonstrated, the national capital calls for some sort of intervention to tackle this challenge. Accordingly, on Monday, the city got a ‘smog tower’ behind the Shivaji Stadium metro station so that it can assist in improved combating the challenge of air pollution that Delhi witnesses every single year. According to a report in IE, the whole structure has a height of 24 metres, which includes a concrete tower 18 metres higher, with a canopy on top rated that has a height of 6 metres. Collectively, the structure is about as tall as an eight-storey constructing.
The base of the structure includes a total of 40 fans, 10 fitted on every side, and every fan has the capability of discharging 25 cubic metres of air every single second. This signifies that as a entire, the tower has the capacity to discharge a whopping 1,000 cubic metres of air per second. Not only that but inside the tower are 5,000 filters placed in two layers. Both the fans as properly as the filters have been imported from the US, the report added.
The mechanism of the tower is a downdraft air cleaning program. The program was created by the University of Minnesota in the US, and IIT Bombay paired up with the university to duplicate the technologies in India. The project was implemented by Tata Projects Limited. When the fans at the base of the tower begin working, the air gets sucked in from the top rated of the tower at a height of 24 metres. It travels downwards, going by way of the two filters, in which the macro layer filter traps particles that are 10 microns in size or bigger and the micro layer filters out particles of about .3 microns. The filtered air is then released at the bottom of the tower by way of the fans at a height of about 10 metres.
A computational modelling carried out by IIT Bombay has recommended that the tower could influence the air good quality in a variety of 1 km from the tower. However, the actual influence would be measured by IIT Bombay as properly as IIT Delhi in a pilot study more than a period of two years. Moreover, an automated SCADA or Supervisory Control and Data Acquisition program has also been incorporated in the tower, and it would monitor the good quality of the air, which includes levels of PM 2.5 and PM 10 particles, temperature as properly as humidity. These metrics would be monitored constantly and displayed atop the tower.
However, as per specialists, there is not adequate proof that would prove that such smog towers are powerful.
