Material
Power saving	Monthly power consumption 624 degrees/686 yuan	Monthly power consumption 1800 degrees/1980 yuan
Time saving	3 days (4 working hours)	3 days (8 working hours)		more than 4 days
Safety	High (indoor)	Low (outdoor)
Fan	Long indoor service life (6 years)	Short Outdoor Service Life (3 years)
Material	Indoor (8 years)	Outdoor (4 years)
Noise	65db	115db		more than 50db	Over 16db: 11,200 yuan/month
Purification	Yes	No
Environmental protection	Yes	No
Protection of the body	Yes	No
Risk warning	Great protection	Confronted with inspection, shutdown and rectification

Conclusion:

1. Now invest 100,000 yuan at a time, and earn money back in 6 months;
2. When the environmental tax is collected in January 18, we can strive for a "half collection" preferential policy;
3. The noise of the wind turbine is up to standard (the national standard is 85 decibels during the day and 75 decibels at night).
4. It is equipped with purified emissions to avoid the fear of future environmental protection inspection.
5. You can apply for the national subsidy policy for the workshop environment transformation, about 30% of the project transformation amount;

I. How to solve the problem of poisonous and harmful gases caused by amino-baking insulating paint, soldering furnace and ferrochrome in the workshop on the fourth floor, and return a fresh air to the workshop.

Chemical composition of insulating paint: formaldehyde, toluene, dimethyl ester, etc.

Solder Smoke:

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 lung, kidney, liver, skin, and intestine.
First of all, the pollution source (2 soldering furnaces, 2 dip ovens), the original dip room area (8m2) door to improve the sealing degree, in the special room of the soldering furnace at 20m2, isolated from the workshop, the soldering furnace through the fume purification The exhaust gas purifier collects and purifies the discharge in the outdoor building. Then, through the new fan, the filtered and clean air is circulated within 6-12 hours per hour, and the workshop maintains fresh air.

II Purification effect diagram of workshop:

III Fresh air process flow:
The outdoor air enters the new fan through the upper air inlet, and is filtered by the primary and middle to achieve clean air. The air outlet is continuously distributed to the localities through the air outlet. The lower air passes through the 20cm pipe arranged in the wall, and the bad air in the workshop passes through the snorkeling fan to the exhaust gas purifier through two suction vents; the two lacquer boxes smell odor through the cm15cm pipe through the sag The exhaust gas purifier is net filtered by a new outdoor fan to achieve clean emissions. The pollution that we filter into the paint room is more serious. The fresh air designed to clean every hour produces 10-15 internal circulations in this space to keep the workshop clean air forever.
