Performance testing device and method of salt mist filter material for marine environment

Abstract

The invention discloses a performance testing device and method of a salt mist filter material for a marine environment. The performance testing device comprises a sealed box body and a power supply, wherein a water tank, a pressure difference meter and an air filtering box are arranged inside the sealed box body, and the water tank is provided with an ultrasonic atomizer; a tested salt mist filter material, an ECM environment corrosion monitor and a blower are arranged in the inner cavity of the air filter box, and the inner cavity of an anti-corrosion box body is divided into a front cavity and a back cavity which are independent of each other by the tested salt mist filter material; the ECM environment corrosion monitor and the blower are positioned in the back cavity, and an air outlet of the blower is connected with a vent to form a performance testing environment of the tested salt mist filter material; the environment corrosion rate and corrosion grade of the back cavity of the air filter box are detected by the ECM environment corrosion monitor in real time, and the pressure difference value between the front cavity and the back cavity is detected by the pressure difference meter in real time. Therefore, the filter effect, filter durability, service life and recycling use durability of the tested salt mist filter material can be accurately tested.

Description

technical field [0001] The invention relates to a performance testing device for a marine environment salt spray filter material and a performance test method using the device, wherein the performance of the marine environment salt spray filter material includes filtering effect and durability. Background technique [0002] In coastal and marine environments, due to the violent disturbance of seawater in the ocean, broken wind and waves, and waves hitting the shore, a large number of foams and bubbles are generated. When the bubbles burst, tiny water droplets will be generated. Most of the seawater droplets fall due to gravity, and some of them are in the same vortex. Diffusion maintains a balanced state and distributes on the sea surface. They rise into the air with the airflow and evolve into a diffuse system through processes such as cracking, evaporation, and mixing. Salt spray has a corrosive effect on metals, and is particularly sensitive to corrosion for electrical co...

AI Technical Summary

Problems solved by technology

Salt spray has a corrosive effect on metals, and is particularly sensitive to corrosion for electrical components, which are precision products. Slight corrosion may lead to failure of electrical equipment, serious losses for shutdown and maintenance, and may even lead to short circuits and major safety accidents such as fires.

[0003] Salt spray filter materials can effectively filter salt spray particles in the air, but the filtering effect and durability of salt spray filter materials from various manufacturers vary widely

Sophisticated electronic equipment is expensive, and the cost of damage and replacement is expensive. It is necessary to use salt spray filter materials to purify the environment
