Background:

Carbon monoxide CO is the main occupational disease hazard of metallurgical steel enterprises. There are many operating points, a wide range of distribution, and a wide range of contacts. Gas poisoning accidents often occur every year, and the harm to the happiness of workers and families is far-reaching. Of.

The effect of carbon monoxide CO concentration on the human body:

The allowable exposure concentration of 50ppm can be exposed for 8 hours (OSHA).

200ppm may cause mild forehead headache within 2 to 3 hours.

400ppm Headache and vomiting after 1 to 2 hours, dizziness after 2.2 to 3.5 hours.

800ppm headache, dizziness, vomiting within 45 minutes. If you are in a coma within 2 hours, you may die.

1600ppm headache, dizziness, vomiting within 20 minutes. He fell into a coma and died within 1 hour.

3200ppm Headache and dizziness within 5 to 10 minutes.If you are unconscious for 30 minutes, there is a risk of death.

6400ppm headache and dizziness within 1 to 2 minutes. Inawareness for 10 to 15 minutes, there is a risk of death.

12800ppm immediately unconscious. There is a risk of death within 1 to 3 minutes.

The highest allowable concentration of carbon monoxide CO stipulated by the state:

1. Occupational exposure limit (GBZ2-2002)

It can communicate with the computer, monitor the concentration of the on-site probe in real time through the upper computer on the computer, and store, analyze and print data on the computer.

Detection gas: carbon monoxide CO, oxygen O2

Sensor: Electrochemistry

Description:

The system monitors the potentially harmful gases of the steel smelter for 24 hours a day, and through the 4-20mA signal Transported to the DCS system for centralized monitoring, on-site detection of harmful gas generation or oxygen concentration drop to make sound and light alarm action.
