The polyvinyl chloride polymerization reactor equipped with a kettle top condenser independently developed by Tangshan Sanyou Group has recently been granted a patent by the State Intellectual Property Office. The condensing device is applied to the top of a 70m3 polymerizer kettle and is the first in China. The application of this patented technology can shorten the reaction time of a single polymerization reactor by 40 to 50 minutes, and increase the annual production capacity by about 4,000 tons.
At present, the company's chlor-alkali primary and tertiary polymerizers have all used this technology, adding about 24,000 tons of new production capacity and achieving an annual profit of about 8 million yuan. According to the overall deployment, the chlor-alkali second phase polymerization reactor will adopt this technology after this year's overhaul, and the total new capacity will be 48,000 tons.
Tangshan Sanyou Group attaches great importance to scientific and technological innovation, strives to raise the level of production equipment and technology, and increases the competitiveness of enterprises through scientific reduction in consumption and production. Up to now, the Group has accepted 63 new technologies such as solid and liquid water coexistence and production of low-salt heavy-duty soda ash. The patents for high-whiteness and strong denier viscose staple fiber and their production process, and their own return alkali weight have been accepted. 46 technologies such as quality soda steam calciners have been granted patents by the State Intellectual Property Office. The group has also won several honorary titles such as the China Chemical Industry Technology Innovation Model Enterprise and Hebei Province Intellectual Property Advantage Development Unit.
