Salvage ship for cleaning suspended substances through differential pressure suction

Abstract

The invention relates to a salvage ship for cleaning suspended substances through differential pressure suction, which is composed of a ship body and a salvaging device; the ship body is a carrier for the salvaging device; the salvaging device comprises an underwater through-flow pipeline, a water pump, a filter screen, a compression air nozzle, and a suspended substance collecting hopper; the underwater through-flow pipeline is arranged in the ship body and extends from a ship head to a stern; the water pump and the filter screen are arranged in the underwater through-flow pipeline; the water pump is started and a pressure difference is formed between both ends of the underwater through-flow pipeline; mixed water of the underwater mixed suspended substances of the ship head is flowed from the ship head to the stern at high speed, and filtered by the filter screen in midway; the suspended substances in the mixed water is stopped by the filter screen, and water is sprayed out from the stern to form a pushing force for the ship advancing. The suspended substances stayed on the filter screen are blown to the suspended substance collecting hopper through the compression air nozzle. The salvage ship has the advantages of being new in design, reasonable in structure, good in suspended substance salvaging effect, high in efficiency, low in cost, energy-saving, environment-friendly, and others.

Description

technical field [0001] The invention relates to a salvage ship for cleaning suspended matter in water, in particular to a salvage ship for cleaning suspended matter in water such as cyanobacteria, water-insoluble inorganic matter, organic matter, mud sand, clay, microorganisms, etc. by means of differential pressure suction. A cleaning salvage ship belongs to the technical field of environmental protection equipment. Background technique [0002] Suspended solids (Suspended Solids) refer to solid substances suspended in water, with a particle diameter of about 10-4mm or more. These particles are mainly composed of sediment, contaminated soil, protozoa, algae, bacteria, viruses, and high-molecular organic matter, and are often suspended in the water flow. Suspended solids are the main source of turbidity, color, and odor. The organic suspended solids in the water body are prone to anaerobic fermentation after deposition, deteriorating the water quality. Therefore, the conte...

Problems solved by technology

The physical salvage method is mainly in the form of manual salvage, which consumes a lot of manpower, material resources, and financial resources, and is labor-intensive and time-consuming; the chemical reagent killing method is mainly aimed at blue-green algae, which will cause secondary pollution

Of course, there are also equipment that use machinery to achieve physical salvage purposes, but it is still in its infancy
