Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "mounted on" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-9, an embodiment of the present invention provides a purification carbon, which includes a body 1 and a plurality of purification channels 11 distributed on the body 1, wherein the purification channels 11 are distributed in an array and penetrate through the body 1 along the same direction, and the aperture D of the purification channels 11 is 1.0 mm-2.0 mm.

It can be understood that a plurality of purification channels 11 penetrate the body 1, the purification carbon is honeycomb-shaped, the gas passes through the purification channels 11 and adsorbs pollutants in the gas, such as formaldehyde, and the pore diameter D of the purification channels 11 has a certain influence on the gas passing. Wherein the aperture D is understood as: the longest line segment through the geometric center in the cross-section of the purification channels 11, and the geometric figure is substantially porous. In this embodiment, the pore size D of the same piece of purified carbon is the same, and in other embodiments, the pore size D of the same piece of purified carbon may be different.

Resistance simulation experiments are carried out on the purified carbon with different apertures D, and it can be found that the resistance is reduced along with the gradual increase of the apertures D. As shown in fig. 5, the relationship between the pore diameter D of the purification pore canal 11 and the resistance is that when the pore diameter D of the purification pore canal 11 is between 1.0mm and 2.0mm, the resistance to air is small, and the purification efficiency is improved. If the aperture D is too large, the purifying carbon is not easy to adsorb pollutants in the gas, and the efficiency of air purification is influenced. If the aperture D is too small, the resistance to air is too large, which is not beneficial to air passing through the purification carbon, and especially when the aperture D is less than 1.0mm, the resistance rises quickly.

Specifically, the experimental simulation conditions of fig. 5 are: the purifying carbon with the cross section of the purifying pore canal 11 being a regular quadrangle and the wall thickness being 0.6mm is adopted, wherein the wall thickness is understood as follows: the smallest distance between adjacent purification channels 11.

The cross-sectional shape of the purification channels 11 may be an irregular geometric figure or a regular geometric figure (e.g. a regular polygon or a circle), and the cross-sectional shape is substantially porous. In one embodiment, the cross-sectional shape of the purification pore canal 11 is a regular quadrangle or a regular hexagon, such as the purification carbon shown in fig. 1, the cross-sectional shape of the purification pore canal 11 is a regular quadrangle, in this case, the pore diameter D is a diagonal of the regular quadrangle, and the wall thickness a of the purification pore canal is a distance between two adjacent sides of the regular quadrangle.

As shown in fig. 2, the cross-sectional shape of the purification channels 11 is a regular hexagon. At this time, the aperture D is the diagonal of the regular hexagon, and the wall thickness A of the purification pore channel is the distance between the adjacent sides of the two regular hexagons.

In one embodiment, the cross-sectional shape of the purification channels 11 is circular, such as the purification carbon shown in fig. 3 and 4, and the cross-sectional shape of the purification channels 11 is circular. The aperture D is the diameter of the circle, and the wall thickness A of the purification pore channel is the minimum distance between the two circles.

In one embodiment, the purification channels 11 in adjacent rows are distributed in a staggered or aligned manner. As shown in fig. 1 and 3, the purification channels 11 in adjacent rows are distributed in a positive way, i.e. distributed in a row; as shown in fig. 2 and 4, the purification channels 11 in adjacent rows are distributed in a staggered manner, i.e., in a staggered manner. The purification carbon distributed in a staggered way is beneficial to saving space and increasing the area for air to pass through.

Simulating the resistance of the purification carbon of the purification pore canals 11 with different cross section shapes, calculating by adopting Icepak software, assuming constant flow, an inlet as a velocity boundary and an outlet as a pressure boundary condition, wherein the calculation method adopts a SIMPLE algorithm and a zero equation model, the convergence standard of each equation is set as 10^-3The parameters of the simulation experiment are shown in table 1 below:

TABLE 1 Table of the pressure drop of the purified carbon with different cross-sectional shapes of the air passing through the purification channels 11 during the experiment

According to the test results, the pressure drop, i.e., the resistance, of the purified carbon having the cross-section of the purification channels 11 in the shape of a regular quadrangle is minimized while maintaining substantially the same porosity. Wherein the "purified carbon cross-sectional dimensions" in table 1 are understood to be: the size specification of the purification carbon on the cross section vertical to the extending direction of the purification pore canal 11; "high" is understood to mean: the length C of the purge channel 11; the length C of the purification channels 11 may be set as desired, and in one embodiment, the length C of the purification channels 11 is 30 mm.

The wall thickness A of the purification pore canal can be set according to requirements. The wall thickness value is too large, the resistance is too fast increased along with the wind speed, the wall thickness value is too small, and the processing is difficult in the process. In one embodiment, the simulation of the purification carbon with the cross section of the purification pore canal 11 being a regular quadrangle is performed, and the simulation result shows that: after the wall thickness exceeds 0.6mm, the resistance is increased too rapidly along with the wind speed, and the wall thickness is preferably 0.3 mm-0.6 mm by combining the actual processing technology. The wall thickness A of the purification pore channels can be kept consistent or different in the same purification carbon block.

As shown in fig. 6, the cross section of the purification duct 11 is a regular quadrilateral purification carbon, and when the side length of the regular quadrilateral is 0.9mm and the wall thickness a of the purification duct is 1.3mm, the pressure drop (Δ P) is in the range of "0 Pa to 900 Pa".

As shown in fig. 7, the cross section of the purification pore canal 11 is a regular quadrilateral purification carbon, and when the side length of the regular quadrilateral is 0.9mm and the wall thickness a of the purification pore canal is 0.4mm, the variation range of the pressure drop (Δ P) is "0 Pa to 200 Pa". Therefore, when the thickness is 0.4mm, the resistance of the purified carbon to the formation of air is small as compared with fig. 6.

As shown in fig. 8, the cross section of the purification pore canal 11 is a rectangular purification carbon, and when the side length of the rectangular purification carbon is 1.4mm and the wall thickness a of the purification pore canal is 1mm, the variation range of the pressure drop (Δ P) is "0 Pa to 200 Pa".

As shown in fig. 9, the cross section of the purification duct 11 is a rectangular purification carbon, and when the side length of the rectangular purification carbon is 1.4mm and the wall thickness a of the purification duct is 0.4mm, the variation range of the pressure drop (Δ P) is "0 Pa to 80 Pa", and the resistance to the formation of air is large. Therefore, the resistance of the purified carbon to the formation of air is smaller at a wall thickness of 0.4mm as compared with fig. 8.

Preferably, the wall thickness a of the purification channel is 0.4 mm.

Of all the purification channels 11, the outermost ones are the edge purification channels 11; on a cross section perpendicular to the extending direction of the purifying pore canal 11, the minimum distance between the edge purifying pore canal 11 and the outer surface of the body 1 is the wall thickness B of the body; the wall thickness B of the body and the wall thickness A of the purification pore channel meet the strength range of the purification carbon.

In one embodiment, the body wall thickness B is greater than the purge channel wall thickness a. The wall thickness B of the body plays a role in supporting and protecting the purification carbon, ensures that the purification carbon is not easy to break when in use, and has better strength.

In one embodiment, the wall thickness B of the body of the purified carbon is 0.45 mm-0.9 mm.

On the cross section perpendicular to the extending direction of the purification pore canal 11, the size of the body 1 can be set according to the needs, and the size can be accepted when the strength range is satisfied. In one embodiment, the length and width of the body 1 are 70mm × 70mm to 25mm × 25mm, so that the purified carbon is conveniently packaged into a filter screen at the later stage, and the packaging flexibility is increased. In addition, the shape of the body 1 can be square or round or other irregular shapes, and only the use requirement is met.

The embodiment of the utility model provides a purify charcoal, the effect that has one of following at least: when the aperture D of the purification pore canal 11 of the purification carbon is between 1.0mm and 2.0mm, the resistance to air is small, and the purification efficiency is improved; the wall thickness A of the purification pore canal is 0.3 mm-0.6 mm, so that the air resistance can be reduced, and the process effect can be ensured; the wall thickness B of the body is 0.45 mm-0.9 mm, so that the strength of the purified carbon is ensured; the cross section of the purification pore canal 11 is square purification carbon, so that the resistance is minimum; the staggered distribution of the purification pore canals 11 is beneficial to increasing the area for air to pass through.
