Now everyone's awareness of environmental protection is getting stronger and stronger, and everyone is paying more and more attention. In the field of new energy, everyone has different opinions on the problem of solar panel pollution. The following small series objectively summarizes several points for your reference.
1. After the calculation, the energy consumed in the whole process can be recovered by solar energy in a few months.
2, the production process pickling waste acid is used as hazardous waste for other companies to reuse (enterprise strictly in accordance with environmental standards to operate, is not a problem).
3. Nitrogen oxides, fluorides, dust and hydrogen chloride produced during the production process are all reduced by spray towers and dust collectors. The wastewater is generally flocculated and precipitated. It completely meets the gb8978 standard. Most of the waste residue is silicate waste residue, which is generally solid waste.
4. There is no enterprise that buryes silicon tetrachloride. 1. The filling of silicon tetrachloride indicates that the plant has no ability to convert hydrogen chloride (silicon tetrachloride to trichloro), and the cost will far exceed that of the peers. 2, silicon tetrachloride can sell money.
About silicon material: 1. It is a manufacturing and processing industry. The polycrystalline silicon is placed in a crucible and the ingot is cut into pieces, and the film is formed. Basically, it is acid and dust. All are well handled.
5. It is also impossible to directly discharge trichlorosilane tetrachloride because this material decomposes into moisture in the air and becomes hydrogen chloride fumes and silica powder.
To sum up, the old process pollution of poly silicon production in the past is relatively large. Domestic small factories have saved a lot of post-processing links and labor protection measures in order to control costs, so pollution and harm are very great.
However, the real norm of large-scale production of poly silicon can achieve environmental protection and low emissions and low cost. Our company adheres to the philosophy of "survive by quality, develop by quality". We are 100% in production and comply with ISO9001 quality standards. The process has strict quality control.
