Description

A melt-blown fabric filterability detection device for epidemic prevention gauze mask

Technical Field

The utility model belongs to the technical field of detection device, especially, relate to a melt-blown fabric filterability detection device for epidemic prevention gauze mask.

Background

In the existing detector, a prepared NaCl solution or DEHS/PAO solution and the like are sprayed out from an aerosol generator, unnecessary large particles are collected into a collecting bottle through a classifier (an inertia principle), and the aerosol particles meeting the requirements are sprayed out from a nozzle of the aerosol generator to enter a test system. The aerosol emitted by the aerosol generator needs to be treated twice before reaching the test filter material: aerosol salt particles are produced by mixing with heated gas (for salt spray). The static electricity charged in the aerosol is neutralized by the static neutralizer, and the effect of the loss of particles and the influence of the static electricity on the test result is reduced. After the aerosol is processed by the two procedures, the aerosol reaches the surface of the tested filter material at a certain flow velocity (flow rate), the testing procedure is started, and for the filtering efficiency test, the testing time is short, and the test on one filter material can be completed only within a few seconds. The loading experiment test is relatively long, the quantity concentration or the mass concentration of aerosol at the upstream and the downstream of the filter material is measured through a particle counter or a laser scattering photometer, the filtering efficiency is calculated, and meanwhile, the pressure drop at the two sides of the filter material is monitored through a pressure difference sensor. The test principle is as follows: an oil mist method: the dry oil-free compressed air enters an aerosol generator at a certain flow rate to generate aerosol with certain particle distribution, and the aerosol is screened by a cascade impactor to discharge particles with particle size distribution meeting the standard requirement from an aerosol outlet and enter a test pipeline. And reach the filter material, the filter material is fitted with the differential pressure sensor both sides, carry on the granule number monitoring to the upstream and downstream granule of filter material in the test process; the whole testing process is carried out at a certain flow rate or air volume. The salt spray method dry oil-free compressed air enters an aerosol generator at a certain flow rate to generate aerosol with certain particle distribution, and the aerosol is screened by a cascade impactor to discharge particles with particle size distribution meeting the standard requirement from an aerosol outlet and enter a test pipeline. Because the salt spray aerosol generates static electricity, the salt spray aerosol needs to be neutralized. And for salt spray aerosols, they are heated to produce salt particles. The method comprises the following steps: the aerosol produced to meet the particle size requirement is mixed with heated gas and then the moisture in the aerosol is evaporated to produce salt particles. And reach the filter material, the filter material is fitted with the differential pressure sensor both sides, carry on the granule number monitoring to the upstream and downstream granule of filter material in the test process; the whole testing process is carried out at a certain flow rate or air volume. However, the detection device does not guarantee a sterile environment and the clamping mechanism of the meltblown fabric is not tight enough, which can have an impact on the end result.
