Device and method for salving water hyacinth

Abstract

The invention discloses a device and a method for salving water hyacinth. Firstly, water hyacinth on the water surface is conveyed into a large funnel at the top end through a conveying belt, and a multi-level roller rolling device is arranged under the funnel. The gaps located between two rollers at each level are arranged downwards and are reduced step by step; and after the water hyacinth on a salvor enters from the large funnel to the multi-level roller rolling device, is rolled by multi-level rollers and is discharged between the final-level two rollers through rolling, the water hyacinth which is originally loose in volume is converted into juice with greatly-reduced volume and a heap of residues as thick as a book, and the water hyacinth salving process is also a water hyacinth treatment process.

Description

technical field [0001] The invention relates to the field of water environment protection, in particular to a device and method for salvaging water hyacinths. Background technique [0002] With the development of industry in modern society, the situation of water pollution is becoming more and more serious. Water hyacinth, a harmful aquatic weed, often breeds in polluted rivers and lakes, causing flooding. If it is not salvaged in time, it will block the waterway. Once the water hyacinth sinks and rots, It will cause further deterioration of water quality, destroy the water ecology, and cause great harm. Now there is a mechanical salvage ship specially used for salvaging water hyacinths. This kind of salvage ship is more suitable for salvaging water hyacinths in small areas, but it is powerless for super large-scale water hyacinths of tens of square kilometers or even hundreds of square kilometers. It is too late to salvage, even if it can be salvaged ashore, it will be pil...

Problems solved by technology

[0002] With the development of industry in modern society, the situation of water pollution is becoming more and more serious. Water hyacinth, a harmful aquatic weed, often breeds in polluted rivers and lakes, causing flooding. If it is not salvaged in time, it will block the waterway. Once the water hyacinth sinks and rots, It will cause further deterioration of water quality, destroy the water ecology, and cause great harm.

Now there is a mechanical salvage ship specially used for salvaging water hyacinths. This kind of salvage ship is more suitable for salvaging water hyacinths in small areas, but it is powerless for super large-scale water hyacinths of tens of square kilometers or even hundreds of square kilometers. It is too late to salvage, even if it can be salvaged ashore, it will be piled up like a mountain, and the handling work is very heavy

Moreover, most of the solutions for water hyacinth are landfill and biogas production. However, if water hyacinth absorbs a large amount of heavy metals and then returns it to the field as biogas fertilizer, it will pollute the soil again, which is a secondary pollution that costs money.
