Embodiment 1

[0040] The invention relates to an indoor air wet oxidation purification method, which comprises the steps of preparing an air-absorbing purifying agent, and then filtering the indoor air and passing it into the air-absorbing purifying agent, and at the same time, it is equipped with ultraviolet radiation and active carbon filtration.

[0041] First, the preparation of the air-absorbing purifier:

[0042] (1) Absorbent mother liquor is made of hydrogen peroxide (30%H 2 o 2 solution), Fe 2+ Ions, sodium oxalate, and hydrochloric acid are configured according to the following ratios.

[0043] Fe 2+ with H 2 o 2 The mol ratio is 1:5,

[0044] If using FeSO 4 ·7H 2 O and a hydrogen peroxide solution with a mass concentration of 30% are configured, and the proportional relationship is 1gFeSO 4 ·7H 2 O plus 30% hydrogen peroxide solution is about 2.6ml.

[0045] Fe 2+ And the ratio of oxalate ion is 1:1.

[0046] The addition of hydrochloric acid is for the purpose of con...

Embodiment 2

[0059] Purification special reactor, as described in embodiment 1;

[0060] Preparation of air absorption purifier:

[0061] (1) Absorbent mother liquor is made of hydrogen peroxide (30%H 2 o 2 solution), Fe 2+ Ions, sodium oxalate, and hydrochloric acid are configured according to the following ratios.

[0062] Fe 2+ with H 2 o 2 The mol ratio is 1:25.

[0063] If using FeSO 4 ·7H 2 O and a hydrogen peroxide solution with a mass concentration of 30% were prepared,

[0064] Fe 2+ And the ratio of oxalate ion is 1:3.

[0065] The add-on of hydrochloric acid is purpose with controlling pH value, and pH value control is 4.

[0066] (2) Dilute the required mother liquor to a certain concentration with distilled water or tap water, preferably at a dilution ratio of 1:7. The diluted reagent is used as the absorption reactant for indoor air wet oxidation purification. And pack in the reactor described in embodiment 1, mix with activated carbon then, the height of activa...

Abstract

The invention relates to a gas purify method, especially a method for humidity oxidation purifying indoor air, wherein the method comprises: preparing air adsorption purifying agent; then filtering the indoor air to ventilate it into the air adsorption purifying agent; radiating it with ultraviolet light, to be filtered with active carbon; the air adsorption purifying agent is prepared from hydrogen dioxide solution, Fe2+ ion, sodium oxalate, and alcaine. And the inventive method can quickly effectively purify the harmful gases of indoor pollution air, as formaldehyde, TVOC, etc.

Description

technical field [0001] The invention relates to a gas purification method, in particular to an indoor air wet oxidation purification method. Background technique [0002] In recent years, indoor air pollution has attracted more and more attention, especially indoor bacteria, dust, and air pollutants caused by formaldehyde, benzene, ammonia, TVOC and other decorations that must be purified and treated. In order to purify and control indoor polluted air, various indoor air purifiers and purification methods have emerged as the times require. According to its purification theory, these air purifiers can basically be divided into the following categories: fiber filter type, activated carbon adsorption type, discharge reaction type, ozone purification type, negative ion purification type, ultraviolet photocatalytic oxidation purification type, etc., or several types A comprehensive purification type that combines purification principles. However, these purifiers and the theory ...
