Advantages of purification equipment: |
||||||
|
1) Energy saving: the energy consumption of the purifier is 5.9 kw/h. |
||||||
|
2) Low noise, easy maintenance. |
||||||
|
3) Deposit in lump sum and withdraw in installments: 10 sets of purifiers are divided into two lines, and 5 sets are used as a group of modules. For example, 10 people can only open one line and 5 sets of equipment to work, and consume 600W; |
||||||
|
4) Purification: It is of great help to employees'health. |

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;
Solder fume, solder paste chemical composition: formaldehyde, toluene, dimethyl ester, etc.
2. On-site test data on the fourth floor: PM2.5 is 13 times higher than the national standard, formaldehyde and toluene are 6.3 times higher than the national standard, and the noise is between 83-92.
For the sake of the employees of the workshop, for the sake of reducing the energy consumption of their own enterprises, a company wants to reduce pollution for the country. Regardless of the consideration, the installation workshop purification is a good deed of merit.

6. Process flow of soldering tin pipeline:
Smoke generated by soldering tin is collected through the hose of "equipment oil fume odor purifier" and ionized and decomposed into carbon dioxide by electrostatic high voltage electric field after primary filtration. Smoke and harmful gases are filtered through advanced filter through pipeline and discharged into the floor through fresh air fan.

8. Flow chart of fresh air process
The smoke leaking from the soldering workshop floats in the workshop, and is collected and filtered by a single-flow new fan installed on the top floor and discharged to the outside through the pipeline to improve the air in the workshop.
