Definitions

  • This invention represents a system reducing infestation of the air, water and soil by poisonous wastes released to the atmosphere by combustion outlets in thousands of residential chimneys and industrial smokestacks around the world. Of all the commercial substances released to the atmosphere, about 200 of them have been identified as possibly carcinogenic. (Carcinogenic As ⁇ esment groupformed in 1976).
  • the gas plays an important role in a process called-g r e e n h o u s e e f f e c t because it tends to reflect heat back towards the Earths surface, that would otherwise escape into space. Too much carbon dioxide could cause a world wide warming trend.
  • the greenhouse effect with a potential for altering climate, melting the polar caps and raising ocean levels can be called as one of the most serious medium and long term environmental issues.
  • Nitric oxide- NO- from motor vehicles, coal and oil furneces,rdadily
  • Nitrogen dioxide-NO 2 -formed from NO produces ozone(causes bronchitis
  • OzoneO 3 formed in sunlight from nitrogen oxides and hydrocarbons(irritates eyes, aggravates asthma) .
  • Chlorine-Cl 2 - from chemical industries, form HCl (irritates mucus membrane) 18.
  • S u l f u r d i o x i d e - SO 2 - and SO 3 - are the major pollutants emanating from industrial plents, coal. oil furnaces and smelters.lt has been the most trouble seme during last several centuries, because of the large scale burning of oil and coal,espacially since the industrial revolution. (The combustion of 10 tons of bituminous coal produces a ton of sulfur dioxide) .
  • N i t r i c a c i d -UNO,- formed from NO 2 - is a major component of acid rain.
  • a colorless and mildly toxic reddish gas, when in the troposphere reacts with ultraviolet rays from the sun. Heat is absorbed by the nitrogen dioxide mole ⁇ ules, which causes oxygen atoms to break loose from each molecule and thereby recreate the nitric oxide gas.
  • a c i d r a i n a composition of two familiar fossil fuels by-products- sulfur dioxide and nitrogen oxide. Apart from these compounds, many other windborne contaminants afflict destruction on distant and unsuspecting victims. Tall smokestacks disperse the pollutants to alleviate some local problems, but it spreads the waste products to previously uncontaminated areas.
  • the aerosol spray was classified as a threat to the ozone layer. Harmless to humans, it does not react with other substances when released into the air. It than rises unchanged through the troposphere and arrives intact in the stratosphere, where it is exposed to ultraviolet Light.
  • L e a d - P B - is a noxious substance from car exhaust recently removed from lead-free petrol. Lead particles can be harmful, be cause when inhaled they enter the blood stream and rupture red blood cells, and also damage cells in the gastrointestinal tract and the central nervous system.
  • Targe particles may remain in the air for only a few second, but others includinglead and smoke particles can stay aloft for weeks-some times rain brings them down, somwtimes by gravity alone, but mostly the windborne particles are deposited by impact when they collide with trees, buildings, hills and other topographic features.
  • the sulfates, nitrates and soot, are most dangerous, because they often lodge in the minute air passages of the lungs, causing bronchial disorders and may possibly generate serious illnesses.
  • N i t r o u s o x i d e - NO 2 - as long as five years after it leaves the ground may fially reach altitudes of 13 miles and above where it is broken apart by the same ultraviolet radiation that creates ozone.
  • ozone killer is m e t h a n e , a carbon hydrogen compound produced by microbes in swamps, rice paddies and the intestines of sheep, cattle and termites, which are responsible for as much as 50% of total atmospheric me than, because they produce enormous amounts of gas as they digest woody vegetation.
  • a single termite mound can emit five litres of methane a minute.
  • O z o n e is a form of oxygen that rarely occurs naturally in the cool layer of the troposphere.lt is created when ordinary oxygen molecule -O 2 - are bombarded with solar ultraviolet rays, usually in the stratosphere .
  • the radiation shatters the oxygen molecules, and some of the oxygen atoms recombine with -O 2 - to form-O 3 -.
  • This configuration can efficiently absorb ultraviolet light. In doing so ozone protects oxygen in lower altitudes from being broken up and keeps most of these harmful rays from penetrating to the Earth surface.
  • Ozone molecules are constantly being made , but they can be destroyed by any numoer of chemical processes, for example by regular injections of nitrogen bearing compound(nitrous oxide ) in the stratosphere ,
  • Nitrogen is quite unreactive at room temperature , although nitrogen atoms are a component of many compounds. The lack of reactivity of molecular nitrogen can be attributed to the very strong triple bond between the atoms in nitrogen molecules. Nitrogen is an essential constituent of all plant and animal tissue in a compound called p r o t e i n .
  • the main attribute of this invention are functional filters and the hot combustion channels removing dust, hard particles and toxic substances from the incoming fumes and gases.
  • the particles toosmall to be removed through glass or cellulosic fibres can be removed through filters made of an activated carbon Kjaterial which absorbs the contaminating gas particles.
  • the system is designed in a modular form and can therefore be utilized in most situations in consideration of size,space,climitic capacity,weight and resource availability.
  • the system as described above can be applied to any house design, at a reasonable cost ensuring that clean air is all that is emitted from house chimneys.lt is a safe,reliable system which could be installed by domestic tradesman.
  • a further application is in event of chemical warfare the treatment process can be used quickly and efficiently to clear the air of toxic chemicals.

Abstract

Systèmes d'élimination de polluants/contaminants dans des gaz d'émission et/ou l'atmosphère par la combinaison de procédés de séparation particulaire, de lavage eau/vapeur d'oxides de soufre, de combustion assistée par l'oxygène de gaz inflammables et de tranmsformation catalytique. On divulgue trois systèmes spécifiques pour l'épuration : i) de fumées de conduits et de cheminées; ii) d'air atmosphérique (à grande échelle); iii) de fumées d'échappement de véhicules à moteur (automobiles, avions, etc.).
