The workshops of many factories produce a large amount of smoke during the production process. The smoke is permeated in the workshop. If it is not dealt with in time and effectively, the concentration of smoke will become higher and higher, which will seriously affect the production order of employees and cause a harsh environment Work efficiency is low, even endangering the health of employees. What can be done to deal with the smoke in the workshop?
The first method is to strengthen natural ventilation and smoke exhaust:
The specific method is to open the original ventilable doors and windows in the workshop, use the natural wind outside the workshop to flow in through the doors and windows, and take away the smoke in the workshop during the natural flow of air, reducing the concentration and the amount of smoke in the workshop. This method is very effective for workshops with a small area, many doors and windows, and good natural ventilation. For workshops with an area of more than 300 square meters and poor natural ventilation, the effect is relatively poor, and the advantage is that it saves money.
The second method is to install a negative pressure fan to forcefully exhaust the smoke:
The specific method is to install a powerful negative pressure fan on the wall or roof closest to the source of smoke. When the negative pressure fan is energized, the negative pressure generated by the large suction volume of the negative pressure fan is used to extract the negative pressure generated by the air to quickly gather in the workshop. The smoke is removed from the workshop along the airflow, and at the same time, fresh and clean air is introduced into the workshop. This method is suitable for large areas and poorly ventilated workshops. The advantage is that the smoke in the workshop is faster, more thorough, and easier to implement. .
The third method is to set up a smoke exhaust duct on the wall of the workshop:
The specific method is to construct a row of smoke exhaust ducts about 50 cm high on the wall surrounding the walls of the workshop more than 2.5 meters, so that the smoke in the workshop rises to the exhaust duct at a faster speed. Using the principle of fast air circulation above, Outside of the smoke removal workshop, this method is suitable for the steel structure workshop with a height of 6 meters or more and the workshop is open without obstructions and obstacles. The smoke exhaust rate is slow, and the smoke exhaust is incomplete.
