After intense installation and debugging, the belt filter press for harmless treatment of drilling waste mud in the drilling site of geothermal geological exploration project in ZK1, Zhenyuan County, Gansu Province officially started operation on the first day of the new year. This equipment can transform liquid mud into solid mud cakes.
In recent years, Qingyang Institute has innovatively integrated the concept of green exploration throughout the entire process of geological exploration. They have vigorously explored the application of new equipment and technologies, actively researched solutions for a "win-win" situation between geological exploration and ecological environment protection, and made efforts to promote dual governance at the "institutional level + technological level". In order to achieve the goal of "no mud on the ground" in geological drilling work, the institute has invested over 200,000 yuan to introduce environmentally friendly treatment equipment such as a belt filter press, solving the problem of post-treatment of mud in the geological drilling process.
The belt filter press developed by Qingyang Institute is a continuous solid-liquid separation equipment with features of compact structure, small footprint, high efficiency, and good operating environment. It consists of components such as frame, transmission device, cloth device, alignment device, tensioning device, washing device, discharging device, pressing roller system, liquid collection tank, and electrical system. It is mainly used for dewatering treatment of sludge with low solid content and without pre-concentration.
At the geothermal geological drilling site in the urban area of Zhenyuan County, the green exploration management system sign is fixed at the prominent entrance of the project, and the belt filter press is also working intensively. The flocculated suspended material is dehydrated of most free water in the gravity dewatering section, and the material is gradually concentrated. Then, the belt filter press flips and discharges the material between the upper and lower filter belts, enters the wedge zone for pre-press dewatering, goes through the main dewatering and radial dewatering, and enters a series of pressure rollers arranged in an S-shape from large to small diameter for final dewatering until a mud cake is formed. In this process, the mud is subjected to squeezing and shearing forces from small to large, which can remove most of the free water and some capillary water.
After repeated verification, the technical experimental results have met expectations. Qingyang Institute not only provides energy resources for local economic and social development, but also protects the local ecological environment through equipment research and development. This marks a further realization of reduction, harmlessness, and greener environmental protection, energy conservation, and low carbon emissions in the drilling construction of the institute.
Facing the new era and new requirements, Gansu Bureau Qingyang Institute will continue to vigorously promote green exploration measures, advance the green exploration work in depth, guard the green mountains and rivers, and demonstrate the responsibility of geological exploration with innovation and wisdom.
