Breakthrough technology in the service of China
An example of Chinese environmental innovators may be useful for guiding emissions-affected industrial enterprises in Russian regions. In the city of Xi'an, a prototype hybrid installation of urban air from harmful emissions and smog was launched.
The air "vacuum cleaner" is at the experimental stage of the project, but has already given an improvement in urban air purity by 19%. The Siyan "anti-smog vacuum cleaner" itself is a pipe 18 meters high and glass roofs with solar collectors with an area of about 10 square kilometers. The installation works like this: it draws in dirty city air and drives it through the pipe through a filter system, where it delivers purified air to the atmosphere of Xi'an at an eighteen meter height. The clean energy for the operation of the anti-smog is provided by the sun, whose rays are captured by the system of panels installed on the roofs.
The cost of this environmental installation in every sense is about $ 2 million, which is not so much for the budget of the Chinese city. According to estimates, up to ten such plants may be needed to completely remove harmful emissions from the city of Xian.
Skeptical doubts are expressed mainly in terms of the appropriateness of using passive solar energy and the need to divert huge sections under it. However, the very principle of cleaning the urban atmosphere is interesting, and the need for it seems undeniable. Residents of the city exhausted by the emissions of Chelyabinsk, for example, would be glad to see a dozen new pipes in the city that would not poison it, but for a change - they would clean it.
