China has launched a giant cleaner smog solar energy
The problem of air pollution from smog is especially relevant in China, as in the period of rapid growth of the industry, few people thought about the safety of the environment. However, in recent years the situation has become almost critical, which is reflected even on people's health. Today, therefore, the Chinese spare no effort and means of remedying the situation. For example, a few days ago in the city of Xi'an (Shaanxi Province) has earned the world's largest plant for cleaning smog. Moreover, this setup works on solar energy, but not quite familiar to us understanding.
The main innovation of the Chinese setup is that it operates in a passive mode. On the ground, a plurality of glass roofs to capture sunlight. The air heated by a system of tubes rises to the main pipe 18 meters. In the pipe contaminated air passes through a series of filters and enters it already purified to the atmosphere. Daily passes through a setting of 5 to 8 million cubic meters of air. Data taken from pollution sensors indicate a decrease in the concentration of particulate matter in the air by 19%. It should also be noted that the cost of construction was $ 2 million, and the total area of all the designs sewage treatment is 10 square kilometers. But despite the successes, environmentalists have a lot of complaints about the work, without a doubt, the correct treatment plant. Firstly, there is no evidence that clears if antismogovaya installation of sulfur dioxide - one of the most dangerous air pollutants. In addition, experts say that a treatment plant - a drop in the ocean. For normal air cleaning needs at least a few dozen of these facilities, and given the considerable area of the complex, this would be very problematic.
