AI Technical Summary

Technical Problem

Existing mixed-flow turbines are prone to being blocked by large impurities and foreign objects during operation, leading to equipment wear, frequent failures, affecting power generation stability and increasing maintenance costs.

Method used

A clogging-resistant mixed-flow turbine inlet filtration device was designed, which adopts a two-stage filtration structure consisting of a main filtration pipeline system and a secondary filtration pipeline system. The device includes an inlet pressurization pipeline system, a main filtration pipeline system, and a secondary filtration pipeline system. The device reduces the scouring of key components by diverting the filtration path and sets up an impurity collection pipeline system for centralized collection of impurities.

Benefits of technology

This effectively reduced the probability of filter box clogging, improved the operational reliability of the turbine and the anti-clogging performance of the equipment, reduced maintenance frequency, and ensured the stable operation of the turbine.

Abstract

The application provides an anti-blocking mixed-flow water turbine inlet filtering device, which comprises a water turbine main body, an inlet pressurizing pipeline system, a main filtering pipeline system and a secondary filtering pipeline system, the inlet of the water turbine main body is connected with the inlet pressurizing pipeline system, the inlet side of the inlet pressurizing pipeline system is connected with the main filtering pipeline system and the secondary filtering pipeline system, the inlet side of the secondary filtering pipeline system is simultaneously connected to the main filtering pipeline system and can divert the inlet water, and the filtered impurities are re-filtered together with the main filtering pipeline system, and then the filtered water is delivered to the inlet pressurizing pipeline system. The application can make the impurities be more fully intercepted by reasonably guiding the water flow to disperse the filtering path, improve the uniformity of water quality, and reduce the probability of filter box blockage and improve the smoothness of the filtering channel due to the realization of the diversion filtering process.
