The Harmful Results Of The Industrial Development

Up to a certain stage of development of human society human activities, in particular, industry did not violate the fundamental natural processes or effected very little on them. Millions of years the ecological balance in nature with preservation of natural ecological systems existed. It continued after the appearence man on the Earth.

The twentieth century was the century of unprecedented technological progress, rapid development of science, industry, energy and agriculture. At the same time as an accompanying factor a harmful impact of human industrial activities on the environment has grown and it continues to grow. As a result we have unpredictable changes of ecosystems and the entire planet Earth.

Currently, with the growth and rapid development of industry great attention is paid to ecological problem namely cleaning and recycling of wastes. In this article we consider one of the types of industrial wastes – gas emissions.

Ways To Control And Reduce Dust

Today we will talk about some of the methods of dust control. Ways To Control And Reduce Dust! The simplest way to allay the dust is to use dust precipitation chamber. It is a large tank, through which the burning gas is transmitted. The rate of gas flow decreases so that the dust settles down on the bottom of the chamber. The greater the volume of the chamber the more smoothly the gas flow moves, and so the cleaning is better.

The most common dust collectors are cyclones. Plain cylinder is a cylindrical casing with the inlet. Ignited gas is introduced into the cyclone, where it makes the motion of the helix. Dust by centrifugal force sticks to the walls and loses its speed, and continuing the circular motion falls into the lower conical part and then into the bunker. Purified gas exits through a central pipe up.

For dust removal different devices are designed. For example, prolong made from polyethylene irrigated by water, hung in the form of ball is very effective and has the ability of self-cleaning from dust.
