Preparation of indoor organic pollution gas purifying agent and process of using

Abstract

The present invention discloses a manufacture and use method for an indoor organic polluting gas purificant. The method comprises the following steps: (1) waste pericarps and other vegetable cutins are collected, and residual pulps and other sundries are removed to get natural vegetable cutins and biological polymers; (2) the vegetable cutins are dried, crushed and filtered with a sieve of 10 to 200 eyes; (3) hydrochloric acid with the concentration of 0.5-6mol / l is added; then after the vegetable cutins with the hydrochloric acid are heated in a water bath for 0.5 to 6 hours, the cutins are flushed with water to be neutral, and a green purificant is got; (4) the green purificant is used absorb and treat organic pollutants in the indoor air; after the purificant is saturated, the purificant is heated under the temperature of 70 to 100 centigrade degrees for 0.5 to 2 hours to be regenerated and recycled. The purificant manufactured with the present invention is provided with the rapid and highly-efficient performance of absorbing the indoor organic pollutants. The absorption capacity reaches as high as 2.0g / g. Moreover, the purificant is free of the temperature, the humidity and co-existing organic pollutants and in particular applicable for purification of indoor compound pollutants. The purificant is cheap and easily obtainable, and can be recycled and regenerated.

Description

technical field [0001] The invention relates to a method for preparing and using an indoor organic pollutant gas purifying agent. Background technique [0002] In recent years, home decoration has approached people's lives, poisonous gas has become an invisible killer, and various cancers and allergic diseases have an upward trend. Nowadays, the pollution is getting worse and worse. About 4% of the diseases in the world are related to the indoor environment. Indoor air pollution is sneaking into the room with the help of decorative materials, endangering people's health. In the past, people paid attention to the harm that air pollution can bring to human beings. However, statistics show that many pollutants in indoor air are 2-5 times that of outdoors, and in a few cases it can be as high as 100 times or more. Indoors include living rooms, office buildings, various vehicles, shopping malls, etc. For most people living in modern metropolises, people's activities are indoors...

AI Technical Summary

Problems solved by technology

The adsorption mechanism of conventional adsorption purifiers (such as activated carbon) is surface adsorption. The adsorption capacity of the adsorbent is limited, and there is a maximum adsorption capacity. Various organic pollutants have competitive adsorption, which is greatly inhibited by humidity, and the adsorption capacity decreases with the increase of temperature.
