Problems solved by technology

At present, the air purifiers on the market are mainly activated carbon and photocatalyst sprays. Activated carbon is not thorough in the treatment of harmful gases, because after the adsorption is saturated, harmful gases are particularly prone to overflow again, causing secondary air pollution; and the existing nano The pure stone adopts a single adsorption pore, which has weak adsorption capacity, low classification rate, weak passive adsorption formaldehyde decomposition ability, easy to cause secondary release of formaldehyde, and short service life. Therefore, it is necessary to develop new air purification materials to avoid existing materials. Deficiencies

[0024] Further, the preparation method of the white particles comprises the following steps:

[0025] a1: Select attapulgite, sepiolite, diatom mud natural mineral materials with adsorption capacity, and photocatalyst purification factor materials;

[0026] a2: Attapulgite, seafoam and diatom mud are purified and then polished separately, and then passed through a 325-mesh sieve for later use;

[0027] a3: modifying the attapulgite, sepiolite and diatom mud after the treatment in step a2;

[0028] a4: Fully mix the attapulgite, sepiolite, diatom ooze and photocatalyst purification factor after the treatment in step a3, and then catalyze it through PROX-NM-DCC technology;

[0029] a5: drying the granules obtained by the granulation;

[0030] a6: performing activation roasting on the dried particles to obtain the second component.

[0031] Further, in step a2, in the purified attapulgite, sepiolite, diatomite and tourmaline, the purity of the effective substance reaches more ...

Embodiment 1

[0033] Embodiment 1, put the nanoclean stone of the present invention in the conical flask, then fill up the smog to the conical flask, so after 2 minutes, it can be clearly seen that the concentration of internal smog decreases, and finally after 4 minutes, the conical flask There is no smoke in the shaped flask at all, indicating that the adsorption has been basically completed.

Embodiment 2

[0034] Example 2, put the nano-clean stone of the present invention into the experimental container filled with water, there will be a large number of air bubbles, and the density of the air bubbles is significantly higher than that of other existing products, which more effectively proves the super strength of the nano-clean stone adsorption.

[0035] To sum up, the design of the present invention adopts PROX-NM-DCC technology, which is composed of diatom ooze, sepiolite and other materials with adsorption properties, and contains abundant nano-scale pores inside, with a pore size of 0.27-0.98 nm Among them, the specific surface area is large and the adsorption capacity is high; its weak electricity enables it to preferentially and strongly adsorb polluting gases such as formaldehyde, benzene, toluene, xylene, TVOC; the added photocatalyst components can decompose the adsorbed pollution It is a harmless gas, so that the nano-cleaning stone can be recycled for more than three ...

Abstract

The invention discloses high-adsorption nano purification stone based on the PROX-NM-DCC technology. The nano purification stone comprises black particles and white particles, the black particles aremade of high-quality nano-mineral crystals, and the nano-mineral crystals have nanoscale pores. The high-adsorption nano purification stone has the advantages that the high-adsorption nano purification stone based on the PROX-NM-DCC technology is formed by compounding a plurality of adsorbing raw materials such as diatom mud and sepiolite, and has rich nanoscale pores inside, wherein the pore diameter is 0.27-0.98nm, the specific surface area is large, and the adsorption amount is high; due to the weak electric property, the nano purification stone can preferentially and strongly adsorb formaldehyde, benzene, methylbenzene, xylene, TVOC and other pollutant gases; added photocatalyst components can decompose adsorbed pollutants into harmless gases, so that the nano purification stone can bereused for more than three years, harmful substances such as the formaldehyde can be quickly oxidized and decomposed into water, and negative oxygen ions are released, so that the aldehyde removal effect is better, and the treatment speed is higher; purification factors are added into the white particles, the PROX-NM-DCC technology is applied to catalyze the white particles, and the aldehyde removal efficiency is improved by ten times.

Description

technical field [0001] The invention relates to the field of nano-clean stones based on PROX-NM-DCC technology, in particular to a high-adsorption nano-clean stone based on PROX-NM-DCC technology. Background technique [0002] In recent years, indoor air pollution caused by decoration problems has become more and more common. Among these decoration pollutions, formaldehyde pollution and benzene series pollution are very harmful to human health and have attracted the attention of people from all walks of life. At present, the air purifiers on the market are mainly activated carbon and photocatalyst sprays. Activated carbon is not thorough in the treatment of harmful gases, because after the adsorption is saturated, harmful gases are particularly prone to overflow again, causing secondary air pollution; and the existing nano The pure stone adopts a single adsorption pore, which has weak adsorption capacity, low classification rate, weak passive adsorption formaldehyde decompos...
