Inertia-stage blades of a water delivery tank with a coating for an air intake filter

Abstract

The object of the present invention is to provide a kind of inertia stage blade of air intake filter device with a coating in the water delivery tank, its section is M-shaped, and it is composed of three water delivery units, wherein the first water delivery unit consists of a diversion section, a delivery section The second water delivery unit is composed of a water delivery tank and a transition section, and the third water delivery unit is composed of a water delivery tank, a transition section and a diversion section; the first and second water delivery units share the transition section, The second and third water delivery units share the transition section, the first and second water delivery units are arranged in mirror images, and the first and third water delivery units are arranged in the same direction. The interior of each water delivery tank is a diversion tank with a coating. The invention can ensure that the total pressure loss level is basically unchanged, relying on the hydrophilic coating on the inner wall of the water delivery tank to capture tiny droplets, and relying on the water delivery coating to catch tiny droplets. Layers form capillary channels to improve water transport capacity. The invention has the advantages of simple structure, convenient processing and low cost.

Description

technical field [0001] The invention relates to an inertial stage blade, in particular to an inertial stage blade of an air intake filter device. Background technique [0002] Inertia blades are installed in the intake filter device of gas turbines to remove impurities such as solids, liquids, and salt mist aerosols in the air. Among them, the liquids in the marine environment are mainly removed, but with the increase of the inlet airflow speed, the blades The water transport burden of the water tank is greatly increased. In order to ensure that the total inlet pressure loss does not increase, the shape of the inertia stage blade body cannot be changed. [0003] The traditional inertial stage blades work between the working conditions of the inlet airflow speed of 1 ~ 7m / s. As the speed increases, the separation efficiency also increases exponentially. [0004] However, with the rapid development of gas turbine technology, the output power of the gas turbine continues to ...

AI Technical Summary

Problems solved by technology

With the increase of the airflow speed, it is more difficult for the device to capture and transport the 0-20 micron droplets. The tiny droplets will form a water film on the wall of the water delivery tank, and the self-weight of the water film driven by the high-speed airflow is not enough to meet the free fall motion.
