The microscope zooms in thousands of haze particles

“People who wear masks give it to people who are busy outdoors: This is Beijing's smog particles collected today. They have complexes, there are biological particles, there are minerals, all sorts of things. Microscope 1000 times (visual ) shooting, the last one is taken at 250 times."

From March 23rd to 27th, Beijing continued to haze and the pollution continued to increase. On the 27th, the AQI index maintained at around 400 for a long time. What are the tiny particles of helium in the air? User @ zhangchao _ shakes the particles by a microscope 1000 times and finds that they have different shapes, complexes, biological particles, and minerals. shocking.

Semi Coke

The production of semi-coke is mostly based on low-temperature dry distillation, and the dry distillation temperature is generally around 600 ℃. Due to the late start, the annual output of a single furnace of semi-coke low-temperature dry distillation equipment is mostly around 30,000 tons/year, and 50,000 tons/year The low-temperature dry distillation furnace equipment of the above scale is still in the exploration and test stage, and the technical process of large-scale equipment is still immature. Only one furnace and multiple doors and other combined technologies can be used to achieve centralized large-scale production.
