Problems solved by technology

However, due to the high density and hardness of the corncob particle material, the inside of each particle body cannot pass through the water flow, and the gap between the corncob particles is relatively large, which is ineffective for filtering micron-sized particles in the water body; For filtering particulates in the air, it is even less feasible due to the large air resistance

Embodiment

[0023] One of the purposes of this embodiment is to provide the use of rush wicks as atmospheric air and drinking water filter materials. The rush wicks can effectively filter particulate matter in air and water, including aerosol particles, heavy metal particles, and bacteria-carrying particles in the air. and various suspended particles in the water. And it can also solve the problem of adsorption of odor gas phase substances in air and water.

[0024] This embodiment also provides a filter structure made of rush wicks, and further provides a filter device including the filter structure. The device further processes the rush wicks into rush wick particles, and makes them form a rush wick layer through technological treatment. The rush core layer can be composed of rush core particles bonded to each other, or can be formed by other filtering mechanisms, and the rush core layer can also be processed according to needs to form a sheet or a film.

[0025] The following is only...

example 1

[0035]This example is an experiment to filter PM2.5 in the air using a filter device. The filter device uses a textile layer as an interlayer, and the textile layer has a belt-like structure as a whole. The textile layer is provided with a number of micropores with a diameter of 1 mm, and the interior of the textile layer is filled with rush core particles with a diameter of 2 mm.

[0036] The specific steps of this experiment are as follows:

[0037] A. Prepare an air quality detector, a computer exhaust fan with a power of 1.8w, and a filter cavity made of transparent plastic; then first compress the volume of the filter material filled with rush core particles to 70% of its original volume, Seal the opening of the textile layer as the filter material for this test;

[0038] B. Put the air quality detector into the filter cavity, turn on the fan, and measure the concentration of PM2.5 in the air in the filter cavity at that time to be 487.6 μg / m 3 , which is consistent wit...

example 2

[0041] This example is an experiment of filtering PM2.5 in smoke by using rush wick particles with a diameter of 2mm in the filter structure.

[0042] The specific steps of this experiment are as follows:

[0043] A. Prepare an air quality detector, a computer exhaust fan with a power of 1.8w, a filter chamber made of transparent plastic, two cigarettes of the same weight in the same pack of cigarettes, an office with an area of ​​10㎡, and a diameter of 2mm rush core granules, soft plastic tube;

[0044] B. Seal the windows of the office, and only open a hole with a diameter of 7mm on one of the windows;

[0045] C. Refit the exhaust fan and filter cavity into a simple smoking machine that can be connected to a soft plastic pipe;

[0046] D. Mark the flame-stop mark at the same length position on the two selected cigarettes, remove the original filter element in the disposable filter tip, fill the prepared rush core particles into the filter tip of the cigarette, and press t...

Abstract

The present invention discloses an application of a rush core used as an atmospheric air and a drinking water filtration material, and provides a novel filtering structure of the rush core, the filtration material has good air permeability, permeability and biological activity, is environmentally friendly, and has good filtering effect for particles in water and air. In addition, the invention also discloses a novel filtering device of the novel filtering structure, the novel filtering device comprises a rush core layer composed of rush core particles. The rush core layer is formed by the rush core particles by mutual bonding, and also can be formed by other filtering mechanisms. The rush core used as an atmospheric air and the drinking water filtration material has good air permeability, permeability and biological activity, is environmentally friendly, and has good filtering effect for particles in water and air.

Description

technical field [0001] The invention relates to a filter material, in particular to the use of the rush core, the filter structure, filter device and the preparation method of the filter device. Background technique [0002] With the process of industrialization, the problem of environmental pollution is becoming more and more serious, and the air and water pollution on which people live are also becoming more and more serious. At the same time, various filter materials and technologies have also been produced one after another. At present, the filter materials used for air filtration and water quality filtration are mainly plastic fiber, glass fiber, activated carbon, metal film, etc., which basically use the fluidity of air and water, and adopt the microporous structure of physical interception to air and water. Filtering, and all have good filtering effect. However, the disadvantages of these filter materials are also obvious. First, these materials are mostly non-degra...
