Abstract

The invention belongs to the technical field of environmental protection and relates to an environment-friendly biomass fiber water treatment conditioner. The biomass fiber water treatment conditioner is prepared from, by mass, 40-45% of castor cake dreg alcoholic-alkaline filtrate, 17-28% of complexing agent, 27-30% of castor cake dreg alcoholic-alkaline filter residues and 5-8% of catalyst. According to the biomass fiber water treatment conditioner, due to the fact that the castor cake dregs serve as main synthesis raw materials, a new way for current castor cake dreg resourceful treatment and comprehensive utilization is expanded, matter and energy cycle of the nature is achieved, environmental protection is benefited, and good social benefits, environmental benefits and economic benefits can be achieved.

Description

The biomass fiber water of a kind of castor bean meal synthesis processes conditioner

Technical field

Patent of the present invention belongs to environmental technology field, is specifically related to utilize castor bean meal to process conditioner for Material synthesis biomass fiber water。

Background technology

Semen Ricini is a kind of oil plant industrial crops, belongs to 1 year raw euphorbia plant, and all there is plantation in more than 30 country in the world。China is one of three big cultivating castor-oil plant states in the world, and castor bean yield is only second to Brazil and India。Castor bean contains the Oleum Ricini of about 50%, of many uses in departments such as aviation, medicine, chemical industry。Along with the raising year by year of China's castor bean yield, the development problem of the side-product castor bean meal after castor bean oil expression also increasingly seems important。

The purposes of current castor bean meal is feedstuff。But due to trans-utilization technological means fall behind, toxicity therein is difficult to remove, often go out of use need not or its utilization rate very low, not only cause the waste of resource, but also bring the pollution of environment。

From castor bean meal chemical composition its rich cellulose isoreactivity material known, it is possible to process the raw material of conditioner as synthesising biological matter fiber water。Process conditioner coagulation performance with castor bean meal for biomass fiber water prepared by raw material superior, not only solve the problem of complex utilization of castor bean meal, and be conducive to saving the energy and equipment investment。

Summary of the invention

For solving the problem of complex utilization of castor bean meal, the invention provides a kind of biomass fiber water being Material synthesis with castor bean meal and process conditioner。

The present invention utilizes castor bean meal to prepare biomass fiber water and processes conditioner。First in isopropanol and potassium hydroxide mixed solution, add heat soaking certain time by drying the castor bean meal after pulverization process, take filtrate, filtering residue standby；Then filtrate, complexing agent, catalyst and filtering residue are injected heating in hydrothermal synthesis reaction still, reacts certain time under a certain pressure, be cooled to room temperature, take supernatant liquid concentrating and precipitating, dry precipitate and namely prepare biomass fiber water process conditioner。It is castor bean meal alcohol alkali filtrate 40-45%, complexing agent 17-28%, castor bean meal alcohol alkali filtering residue 27-30%, catalyst 5-8% by each Ingredient percent that biomass fiber water processes conditioner。

Castor bean meal synthesising biological matter fiber water is utilized to process conditioner; not only expand the new way of current castor bean meal recycling treatment and comprehensive utilization; and achieve the matter and energy circulation of nature; do not need main equipment; and dust and noise will not be produced; be conducive to environmental conservation, good social benefit, environmental benefit and economic benefit can be obtained。

Detailed description of the invention

Embodiment one:

Learn from else's experience the castor bean meal dried after pulverizing, heat in the isopropanol and 2.0mol/L potassium hydroxide mixed solution of the 1.5mol/L that volume ratio is 1:3 to 60 DEG C and soak that to take filtrate, filtering residue after 6h standby；Then by filtrate, complexing agent flax glue, catalyst and filtering residue according to mass percent respectively 40%, 28%, 5%, 27% ratio inject in hydrothermal synthesis reaction still and heat to 115 DEG C, 4h is reacted under 1.5MPa, it is cooled to room temperature, take supernatant liquid concentrating and precipitating, at 40 DEG C, dry precipitate namely obtain biomass fiber water process conditioner solid。Described catalyst is trimethyl tetradecyl base ammonium bromide。

Embodiment two:

Learn from else's experience the castor bean meal dried after pulverizing, heat in the isopropanol and 2.5mol/L potassium hydroxide mixed solution of the 2.0mol/L that volume ratio is 2:3 to 65 DEG C and soak that to take filtrate, filtering residue after 7h standby；Then by filtrate, complexing agent flax glue, catalyst and filtering residue according to mass percent respectively 41%, 25%, 6%, 28% ratio inject in hydrothermal synthesis reaction still and heat to 120 DEG C, 5h is reacted under 2.0MPa, it is cooled to room temperature, take supernatant liquid concentrating and precipitating, at 45 DEG C, dry precipitate namely obtain biomass fiber water process conditioner solid。Described catalyst is Dodecyl trimethyl ammonium chloride。

Embodiment three:

Learn from else's experience the castor bean meal dried after pulverizing, heat in the isopropanol and 3.0mol/L potassium hydroxide mixed solution of the 2.5mol/L that volume ratio is 1:2 to 70 DEG C and soak that to take filtrate, filtering residue after 8h standby；Then by filtrate, complexing agent flax glue, catalyst and filtering residue according to mass percent respectively 45%, 17%, 8%, 30% ratio inject in hydrothermal synthesis reaction still and heat to 130 DEG C, 6h is reacted under 1.8MPa, it is cooled to room temperature, take supernatant liquid concentrating and precipitating, at 50 DEG C, dry precipitate namely obtain biomass fiber water process conditioner solid。Described catalyst is dimethyl diallyl ammonium chloride。
