A few days ago, the invention patent "A new type of online opening structure and method for concrete pool wall" declared by Yan'an Refinery was officially authorized by the State Intellectual Property Office, becoming the second invention patent with independent intellectual property rights in the history of the plant, filling the domestic The blank of the online hole-opening technology for concrete pool walls is of great value for the promotion and application of projects with similar online hole-opening requirements
.
In 2018, the plant implemented a sewage upgrading and upgrading project, requiring the installation of return pumps in the biochemical tank, four DN500 holes in the tank wall, and installation of mechanical pump inlet pipelines
.
As the traditional domestic concrete pool wall opening technology needs to discharge all the biochemical sewage, it will cause the entire sewage treatment plant to be paralyzed, and some production devices are facing the danger of shutting down
.
In order to break this dilemma, the technicians of Yan'an Refinery have invented a new type of online hole-opening structure and method for the concrete pool wall.
When the biochemical pool is full of water, the pool wall can be successfully opened once under pressure
.
The pump has been installed safely for more than 3 years, and there is no leakage at the opening
.
According to reports, the newly invented hole-opening technology has obvious advantages.
