Comprehensive test bench and test method for air filter or filter material

Abstract

The invention relates to a comprehensive test bench and test method for an air filter or a filter material. The device is composed of the following four systems: an aerosol generation system, a mixing system, a test system and an automation control system, wherein the aerosol generation system is composed of an aerosol generator, an electric butterfly valve, an electromagnetic flowmeter and a mini vacuum pump; the mixing system is composed of a test box, a low-pressure blower, a humidifier, a surface air cooler, a temperature/humidity sensor and an aerosol detector; the test system comprises a test box, an electric butterfly valve, a flowmeter, a clamp, slide glass, a mini vacuum pump and a high efficiency filter; and the automation control system is mainly connected with all of the electric butterfly valves, the low-pressure blower, the electromagnetic flowmeters and the mini vacuum pumps through a computer control terminal. The test bench provided by the invention is advanced and reasonable in design structure, realizes automation control, and can be easily and quickly operated; and the test bench can test the filter performance of a filter material and can also test the filter effect of a filter.

Description

Technical field [0001] The invention belongs to the field of air purification, and specifically relates to an air filter or filter material comprehensive test bench and a test method. Background technique [0002] In modern cities, the degree of indoor air pollution is many times higher than that of outdoors. More importantly, more than 80% of the urban population spends 70% of their time indoors. Children, pregnant women and chronic patients, because they stay indoors It takes longer than other people, and the harm from indoor environmental pollution is more significant. According to the World Health Organization (WHO), 100,000 people worldwide die of asthma due to indoor environmental pollution every year. In response to the current situation of indoor air pollution, in order to create a relatively clean indoor environment, more and more families use indoor air filters. Many domestic and foreign manufacturers have introduced different types of filters in order to meet market n...

AI Technical Summary

Problems solved by technology

However, since the country currently has no quality standards and corresponding standard testing methods for air filters, it is difficult to determine the actual effect of the filter.

At present, several popular filtering effect detection methods are relatively rough and cannot reflect the purification effect of the filter well. [1] , and at this stage, the test bench for its filtration efficiency has the following defects: (1) Most of the test bench test objects are relatively single, and only a single test of the filtration effect of the filter material

For example, in 2014, the China Patent Office announced that the authorized announcement number is CN 102854087 B's invention patent, named "A Test Platform for Air Filtration Material"; (2) Without considering other conditions, such as temperature, humidity, etc. impact, the best purification conditions cannot be determined, and the shortest purification time cannot be determined. For example, in 2015, the China Patent Office announced that the application publication number is CN 105043672 A for an invention patent, and the name is "A High Efficiency Filter PAO Test Device"
