The problems existing in the workshop on the sixth floor:

Workshop formaldehyde, xylene 11-22.5 times / m3, PM2.5 super national standard 13 times / m3; (national standards: formaldehyde, xylene: 0.1mg / m3; PM2.5: 75mg / m3)

Renovation Concept: Renovation of Bad Air in SMT Workshop on the 6th Floor

1. Key pollution sources: 8 stations of solder are directly discharged indoors through the "equipment fume odor purifier", and can also be discharged to the outdoor floor; reflow soldering installation of two "equipment fume odor purifiers" using existing pipelines Outdoor; wave soldering also installs two "equipment purifiers" that use existing pipelines to discharge directly to the outdoors.
2. The outdoor air enters the new fan through the upper air inlet, and is filtered by medium and high-grade to achieve clean air. After 5 Ф20cm main pipes, 15 outlets continuously and cleanly distribute the clean air to all places. The new air blower is arranged on the wall 20cm pipe, and the bad air in the workshop is cleaned and discharged to the outdoor floor through the new air blower through 9 air suction ports. The pollution from the filter to the workshop is serious. The designed clean air per hour produces 10-15 internal circulations in the space, so that the workshop always keeps clean air.

 

I Solder smoke is harmful to the body:

1. Soldering fumes, chemical components of solder paste: formaldehyde, toluene, dicarboxylic acid ester, etc.;

 

Soldering fumes:

 

Lead: Lead is not an essential element of the human body. Its toxicity is concealed and slow. Lead can enter the human body through the digestive tract, respiratory tract or skin, and the toxicity to humans is cumulative. Lead is absorbed and circulated in the blood. Except in the liver, spleen, kidney, brain and red blood cells, most (90%) are also present in the bone as stable insoluble phosphate. Lead is a chemical substance that is potentially carcinogenic to humans. The target organs are the lungs, kidneys, and liver.

Industry pain point
 
The formaldehyde exceeds the national standard: 22.5 times, and the PM2.5 exceeds the national standard by 0.5 times;

II Case：

III Summary:

For the sake of the employees of the workshop, for the sake of reducing energy consumption in their own enterprises, a company wants to reduce pollution for the country. No matter from which considerations, the purification of the workshop is one, a good deed of merit.

Summary
1. When the environmental tax is collected in January 18, we can strive for a "half-half" preferential policy;
2. The fan noise is up to standard (the national standard is 85 decibels during the day and 75 decibels at night).
3. Installed clean emissions to avoid fear of environmental inspections in the future;
4. You can apply for the national subsidy policy for the workshop environment transformation, about 30% of the project transformation amount.
