Integrated clay spraying device for red tide treatment

Abstract

The invention relates to the technical field of marine pollution treatment, in particular to an integrated clay spraying device for red tide treatment. The integrated clay spraying device for red tide treatment is divided into a ship body, a storage/feeding system, a material mixing system and a spraying system. A normal design is adopted in the ship body, free carrying is achieved in the treating area, the storage/feeding system is installed on a deck of the ship body and is contained with a material storing bin, a motor, a stirrer, a conveyor, a water bin and the like, continuous feeding is achieved, continuous type mixing of the modified clay and the seawater is achieved, the spraying system and the material mixing system are connected at a water outlet of the material mixing bin, and turbid solution of the modified clay in the material mixing bin is sprayed into a polluted sea area; the massive structure of the integrated clay spraying device for red tide treatment, the design principle is reliable, the production technology is ripe, the using operation is convenient, the practical value is high, and the applied environment is friendly.

Description

Technical field: [0001] The invention relates to the technical field of marine pollution control, and relates to a device for spraying clay to control red tides, in particular to an integrated clay spraying device for controlling marine pollution and red tides. Background technique: [0002] At present, with the continuous development and utilization of the sea, a large amount of industrial wastewater and domestic sewage in the sea flow into the sea, forming an increasingly serious problem of red tide pollution. Therefore, the society urgently needs a feasible and efficient method to control the problem of red tide pollution . There are various methods of red tide control, mainly including chemical methods and physical methods; chemical methods are effective, mainly spraying relevant chemicals on polluted sea areas, using chemical agents to inhibit or even kill algae to control red tide organisms, chemical methods are effective The fastest, according to relevant data, a var...

Problems solved by technology

There are various methods of red tide control, mainly including chemical methods and physical methods; chemical methods are effective, mainly spraying relevant chemicals on polluted sea areas, using chemical agents to inhibit or even kill algae to control red tide organisms, chemical methods are effective The fastest, according to relevant data, a variety of chemical agents for red tide control have been experimentally studied, such as: copper sulfate and slow-release copper ion algaecides, organic algaecides such as chlorine dioxide and isothiazolinone, Ozone, bromogermine and iodophor, etc., the chemical agent used in scale is CuSO 4 , this kind of chemical agent is easily soluble in water, and the effect of controlling red tide is remarkable, but the chemical method of red tide control also has obvious shortcomings. When chemical methods are used to control red tides in places with rapid migration under seawater fluctuations, the persistence of the agents is poor, which can easily cause secondary pollution of chemical agents; physical methods mainly include clay methods, especially the successful development of modified clay, which is also recognized internationally. An effective method for controlling red tide pollution is to use the flocculation of clay particles on red tide organisms to remove red tide organisms

The algae removal rate of the modified clay successfully developed in my country at the present stage can reach 95%-99% in a small experimental field, but when it is applied in a vast sea area, due to the lack of efficient equipment support, the modified clay method to control red tide pollution has not been widely used. It has been promoted and popularized in China; traditional clay spraying equipment has many shortcomings, such as: it is difficult to prepare modified clay on the hull, and it is not easy to continuously, uniformly and efficiently release modified clay in sea areas polluted by red tides, and it is also difficult to pollute sea areas according to Control the dosage of modified clay according to the situation
