Problems solved by technology

The advantages of cotton masks are that they can be reused after cleaning. The disadvantages are that bacteria are easy to breed and reproduce, and they cannot effectively filter small particles. The protection ability is poor, and the quality is also uneven. There is no guarantee.
Disposable medical masks and KN95 masks have the advantages of strong protective effect, good facial fixation, and low price. The disadvantages are short wearing time, non-recyclable, more medical waste, and poor ventilation.

example 1

[0029] Example 1: Use the gas burned by cigarettes as the dust-containing gas, place it on one side of the filter layer, and test the dust removal effect of the electrostatic precipitator mask by setting different variables.

[0030] Set the variable as the distance between the plates is 0.3cm, 0.5cm, 0.8cm, 1.0cm, 1.2cm. Each variable is divided into two situations: energized and non-energized. Each test burns 0.5 cigarettes, and the voltage is 3695V. The specific test data As shown in Table 1 below:

[0031]

[0032] Table 1

[0033] The test results show that the electrostatic dust removal mask has an adsorption effect. Under the same other conditions, the adsorption effect when the electrode plate spacing is 0.8cm, 1.0cm and 1.2cm is better than that of other electrode plate spacing.

example 2

[0034] Example 2: Use the gas burned by cigarettes as the dust-containing gas, place it on one side of the filter layer, and test the dust removal effect of the electrostatic precipitator mask by setting different variables.

[0035] The variables are set to be 0.5 cigarettes, 1 cigarette, and 2 cigarettes respectively. Each variable is divided into two situations: energized and non-energized. The distance between the plates is 1.2cm and the voltage is 3695V. The specific test data are shown in Table 2 below:

[0036]

[0037] Table 2

[0038]The test results show that the electrostatic dust removal mask has an adsorption effect, and the adsorption effect is the best when the air flow is 1 cigarette when other conditions are the same.

example 3

[0039] Example 3: Use the gas burned by cigarettes as the dust-containing gas, place it on one side of the filter layer, and test the dust removal effect of the electrostatic precipitator mask by setting different variables.

[0040] The variables are set as voltages of 3695V and 5257V respectively. Each variable is divided into two situations: energized and non-energized. The distance between the plates is 1.2cm, and the amount of cigarette burning is 1. The specific test data are shown in Table 3 below:

[0041]

[0042] table 3

[0043] The test results show that the electrostatic dust removal mask has an adsorption effect. Under the same other conditions, the adsorption effect of the high-voltage electrostatic field of 3695V is better than that of 5275V.

[0044] Compared with the prior art, the electrostatic dust removal mask of the present invention can replace the traditional filter mask, does not hinder breathing, and can effectively remove suspended particles in th...

Abstract

The invention provides an electrostatic dust removal mask which comprises a mask shell, a filter layer, a power supply device and a fixing band, the filter layer comprises a protective inner shell, a protective outer shell, a metal pole plate, an air inlet window and an inspiration and breathing valve, and the metal pole plate, the air inlet window and the inspiration and breathing valve are arranged between the protective inner shell and the protective outer shell; the metal polar plate comprises a positive polar plate and a negative polar plate which are respectively connected with the corresponding positive wire and the negative wire, the power supply device is electrically connected with the positive wire and the negative wire of the metal polar plate and is used for providing a power supply for the electrostatic dust collection mask, and the fixing band is connected with the mask shell so as to be worn and used. The electrostatic dust removal mask can replace a traditional filtering type mask, breathing is not hindered, and suspended particles in air can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of public health, in particular to an electrostatic dust removal mask. Background technique [0002] The working principle of electrostatic dust removal: air molecules are ionized into positive ions and electrons in a strong electric field. When the electrons run to the positive pole, they encounter dust particles or bacteria, which make the dust particles or bacteria negatively charged and tend to the positive pole. After reaching the positive pole, they release all The charged electrons, dust particles or bacteria are deposited on the positive plate. In the past, electrostatic dust removal was mainly used in heavy industries, such as purifying the waste gas of ironmaking furnaces and coke ovens in the iron and steel industry; purifying fly ash from coal-fired power plants; it is also widely used in the cement industry. Most dryers are equipped with electrostatic precipitators. Dust sources such as cement...
