Uses of water hyacinth

Abstract

The invention relates to a usage of a water hyacinth, in particular to the application of the water hyacinth for preparing the mixed slurry used for producing the synthesis gas or fuel combustion. The mixed slurry used for producing the synthesis gas or fuel combustion, according to the parts by weight, comprising 100-200 parts of carbon matters, 20-150 parts of water hyacinth, 0.001-1 parts of modifier and 0.001-5 parts of dispersant. The slurry consistency of the mixed slurry containing the water hyacinth which is prepared by the invention achieves more than 60wt% and the appearance viscosity thereof is less than 1000mPa.s (25 DEG C). Furthermore, no additional stabilizer is required to be added during the preparation process of the mixed slurry containing the water hyacinth prepared by the invention; furthermore, the mixed slurry containing the water hyacinth generates no hard sediment after being statically placing for a long time and is suitable for pumping.

Description

Uses of water hyacinth technical field The invention relates to the use of water hyacinth. Background technique Water hyacinth, also known as water hyacinth, water lotus, false narcissus, and aquatic hyacinth, is a monocotyledonous perennial plant belonging to the genus Hyacinthaceae. Water hyacinth generally grows in lakes, rivers, ponds and other places, and has strong fecundity and viability. It has a strong ability to purify water bodies. A certain amount of water hyacinth in lakes is beneficial to improving water quality, inhibiting the growth of algae such as blue-green algae, and beautifying the environment. However, just because of its strong fecundity and fast metabolism, if it is not salvaged in time, the roots, stems, leaves, etc. will rot in the water and cause serious pollution to the water quality. So far, water hyacinth has been mainly used as fodder, retting, general fuel or biogas production. Because the calorific value contained in water hyacinth is ...

AI Technical Summary

Problems solved by technology

Because the calorific value contained in water hyacinth is relatively high (its dry basis calorific value is about 13MJ / kg, which is more than half of coal calorific value), therefore, in terms of the application status of existing water hyacinth, its contained calorific value has not yet been fully obtained. use

In addition, since the salvaged water hyacinth contains a large amount of water (water content greater than 90wt%), it needs to be dehydrated before use (especially as a common fuel), which not only requires special dehydration equipment, but also consumes a lot of energy during the dehydration process
