Method for preparing formaldehyde absorbent by using pomace

Abstract

The invention provides a method for preparing a formaldehyde absorbent by using pomace. The method comprises the following specific preparation steps: (1) collecting the pomace obtained by extractionof pectin, wherein the pomace still contains a little of pectin; (2) cooking the pomace obtained in step (1): cooking the pomace with boiled water for 20 to 40 minutes; (3) performing squeezing: adding water to squeeze the pomace to obtain material slag, and further smashing the material slag; (5) performing filtration: filtering the smashed material slag; (6) boiling and drying the filter residues, performing suction filtration to obtain a filter cake, putting the filter cake into a granulator for granulation, putting the granules into a drying oven for drying at temperature of 100 to 105 DEGC for 30 to 40 minutes, taking out the granules, and preparing the formaldehyde absorbent. According to the method provided by the invention, the pomace obtained by the extraction of the pectin is used as the raw material; the pomace is a novel originally ecological biological adsorption material, which is prepared into an economical, practical and healthy substance for adsorbing formaldehyde.

Description

technical field [0001] The invention relates to the technical field of formaldehyde adsorbents, in particular to a method for preparing formaldehyde adsorbents from pomace. Background technique [0002] In recent years, with the gradual improvement of people's living standards, the problem of indoor air pollution has become increasingly prominent, which has aroused widespread concern from all walks of life. As one of the main indoor air pollutants, formaldehyde can enter the human body through the respiratory system and skin, which has potential, universal and long-term harm to the human body. As one of the main pollutants of indoor air, formaldehyde is also the most common, most serious and most concerned pollutant, with a wide range of sources. A large number of studies at home and abroad have shown that a large number of decorative materials, furniture and coatings used in the decoration process are the main sources of indoor air pollution, such as building structural ma...

Problems solved by technology

[0004] At present, the method of removing formaldehyde in China is mainly to use some activated carbon and diatoms sold on the market to adsorb formaldehyde, but the cost of these materials is relatively high, and their adsorption is limited, which is easy to cause secondary pollution, especially activated carbon. The production process will also have a greater impact on the environment
