Development from Russia will help clean up emissions from CHP plants in China

The accelerator developed by the staff of the Tomsk Polytechnic University is being tested at the Xinyang Aerospace Institute (the largest in China). This technology will subsequently be used for the complex cleaning of flue gases, primarily of hazardous emissions from thermal power plants.

The prototype and its tests

At the moment, the prototype of the industrial plant is undergoing the first phase of testing in China. As soon as the first stage of tests is completed, based on the data obtained, the construction of an already full-fledged industrial design that will purify the flue gas through the use of pulsed electron nanosecond accelerators duration.

What is the essence of technology

The technology, which was proposed by TPU researchers, is based on the use of a pulsed electron beam. In the course of numerous experiments, it was found that the use of such a beam allows it is quite effective to remove from the air mass such extremely harmful compounds as nitrogen oxide and sulfur oxide.

In this case, the cleaning system itself is divided into two zones:

1. Irradiation area.
2. Filtration zone.

So, at the first stage, additional gas is added to the contaminated gas, at the next stage, this prepared mixture goes through the phase of irradiation with an accelerator. In this case, strictly controlled processes begin to take place in the formed plasma, as a result of which solid particles are formed.

Then, in the filtration zone, these solid elements settle on special filters, and after cleaning the filters, the resulting mixture can be disposed of or used as a secondary raw material.

And the rest of the gases, already completely cleaned of all harmful impurities, will go outside.

Note. Experiments have shown that the formed sludge is quite suitable for use as mineral fertilizers.

Why is it needed

In fact, the issue of environmental pollution is quite acute. And CHP is the most "dirty" production. Chinese specialists are interested in Russian development primarily because CHPPs are the main source of electricity in the country, and in their locations there are serious problems with ecology.

To minimize the harm done, the country's authorities are looking for all possible ways, and the Russian development seems to them extremely promising. In addition, as it turned out, this installation also copes well with air disinfection. Which is very important in our turbulent 2020.

So, according to the plan of the developers themselves, pulse accelerators will begin to be fully used at Chinese thermal power plants in the next 3-5 years.
