Cars exhaustion



Main problem of ventilating system of garages and parking places is it’s accumulation of toxic substances which produced while cars engines are started. In consequence cars exhaustion concentrating inside a tunnel and around of air wells, through which occurs release of polluted air. Most polluted exhaustion produced in engine starting and heating time, when cars are in garage and parking places.

Cars exhaust contains:

  • Incomplete liquid fuel burning products (CO, soot, hydrocarbons, etc);
  • Air hydrogen oxidizing products – different hydrogen oxides;
  • Polycyclic aromatic hydrocarbons (also benzapyrene)

Note.

In view of ban to production and use of ethylated petrol in RF from 2002 year amount of plumbum in cars exhaustion not counted.

All compounds specified in this list are harmful and hard-to-remove. Concentration of these compounds in garages and parking places can reach amount mentioned in table:

Name of car exhaustion toxic compound Chemical formula Amount in exhaustion of one car in mg/h
Carbon oxide CO 100000
Aldehydes (total) CH2O (formaldehyde)
CH2-CH-CHO (acrolein)
10000
Soot (carbon) C 10000
Simple structure hydrocarbons(total) CH, CH4, C3H6 идр. etc 30000
Benzapyrene C20H12 3000

Amount of toxic compounds in ventilating emissions while both drawing out 10000m3/h and car engines working.

Amount of simultaneously working cars Amount of toxic gases in ventilating emission, mg/m3 Maximum permissible concentration of exhausts in air, mg/m3 Amount of toxic substances after“Gasconvertor “Yatagan”, not more than mg/m3
10 15-25 3 0,3-0,5
20 60-100 3 0,6-1,0
30 45-75 3 0,8-1,5
50 75-125 3 1,5-2,5
100 150-250 3 3,0-5,0

Exhaustion toxic compounds differently influence human organism. Hydrogen oxide cause oxygen starvation and affect central nervous system. Aldehydes (formaldehyde, acetaldehyde, acrolein, etc) irritate mucous tunics and affect central nervous system. Benzapyrene, polycyclic aromatic hydrocarbons, anthracenes are carcinogenic substances. They are strong poisons, influence food poisoning, and destroy respiratory organs and nervous system.

Nowadays main and the most popular method of neutralization previously mentioned effect is dispersion of ventilating emissions from tunnels. This lead to appearance of polluted areas around air wells. This pollutions concern not only air but also soil and surface reservoirs.

To make air, soil and surface reservoirs more cleaner “Ecopromika” company developed and produces gas cleaning equipment complex which based on plasma gas-discharge-catalytic air cleaning technology – “Gasconvertor “Yatagan”.

For today these type of equipment has the best “cost-quality” and “efficiency-dimensions” performance, practically doesn’t have replaceable parts, doesn’t need wastes utilization and has lowest cost of operation. “Gasconvertor “Yatagan”installations sterol cleaning efficiency confirmed by many tests on a stand in laboratory environment and operating enterprises.

Rest on field experience of   “Gasconvertor “Yatagan” on a different enterprises, related to motor transport operation:

  • To clean ventilating emissions from exhaustion gases use  “Gasconvertor “Yatagan X,X - 1000”  and  “Gasconvertor “Yatagan X,X - 2000”
  • To clean air in recycling ventilating systems use  “Gasconvertor “Yatagan  X,X – 200R”

“Gasconvertor “Yatagan” installations to clean air from exhaustion used like part of ventilating systems (combined extract and input ventilation, recycling ventilation), or like separate local air cleaner.
