Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0015] A composite biomass filter material, which is uniformly mixed with the following mass percentages and then pressed and molded at 80-120°C: 70%-80% of biomass particle fragments, 20%-30% of diatomite ;

[0016] Among them, the biomass particle fragments are obtained by the following method: drying the biomass raw material to a moisture content of 15wt% to 20wt%, and crushing the biomass raw material to a particle size between 3mm and 5mm, and then soaking in petroleum ether 2 hours, take out and continue to dry the biomass raw material until the moisture content is less than 10wt%, and grind again until the particle size of the biomass raw material is less than 1.5mm to obtain biomass particle fragments; the oven temperature is 90-110°C. Due to the high water content of the raw ...

Abstract

The invention discloses a composite biomass filtering material which is prepared from the following materials through uniform mixing and then compression molding: 70-80% of a granular biomass crushed material and 20-30% of diatomite. According to the invention, a biomass material and a natural mineral material are integrated creatively, a special porous structure in the diatomite has strong adsorption capacity, and trace metal oxides contained in the diatomite can form colloids at high temperature, so that the viscosity of the composite biomass filtering material is increased, and the composite biomass filtering material has a moisture retention function; the biomass material is derived from living waste materials, so that the biomass material is cheap and easily available in raw materials, and has no pollution to the environment; the filtering material developed in the invention is not only natural, environmentally friendly, and low in cost, but also has an excellent adsorption performance; and the composite biomass filtering material, after being recovered and then subjected to simple treatment, can be used as a boiler fuel, thereby greatly increasing the economic practicability of the filtering material.

Description

technical field [0001] The invention relates to the field of filter materials, in particular to an environmentally friendly and pollution-free composite biomass filter material obtained from natural materials. Background technique [0002] At present, with the rapid increase of population aging worldwide, issues such as pension and medical care have become hot topics in society. By the end of 2013, the elderly population in China had exceeded 15% of the total population. As the population structure tends to age, the medical and pharmaceutical fields are booming, new pharmaceutical factories are constantly being established, and a large number of new drugs are constantly on the market. However, the production of raw materials is also a part of chemical production, and it will produce a certain amount. Production waste, such as filter materials often used in chemical production: 200-400 mesh silica gel. The post-treatment of such substances is often discarded, and such subst...
