Description
Technical field
The invention belongs to the ballast water treatment technical field in boats and ships shipping process, is the crucial filter plant in ballast water treatment system.
Background technology
The trade in commodities in the world more than 80% is all by Shipping.Ballast water is the important guarantee of marine operation safety, it can ensure boats and ships safe, steadily and efficiently run.According to estimates, the ballast water that current global boats and ships carry nearly 12,000,000,000 tons every year, and along with the development of shipping business is still in cumulative year after year.But ballast water causes threat also to ecological environment, social economy and human health.Be present in the biology of travelling around the world with ship in ballast water for ship every day more than 4500 kinds.Migrate caused biotic intrusion and the epidemic transmission etc. of biology in seagoing vessel ballast water in worldwide occur repeatedly to the infringement event of marine environment and the mankind, have caused the extensive concern of international community.Therefore International Maritime Organization (IMO) has formulated " international convention about ballast water for ship and deposit thereof manage and control " (hereinafter referred to as " pact ") on February 13rd, 2004.This pact makes ballast water treatment system become the key equipment that International Maritime Organization's solar obligation is gone on board and " pass " that enter other countries harbour.The ballast water of all foreign-going ships all will meet discharge standard, just can enter object harbour.Therefore, the purified treatment correlation technique of seagoing vessel ballast water and the research of equipment and industrialization will have a direct impact China's shipping economy, the problem of each shipping enterprise in the urgent need to adopting correlation technique to solve ballast water for ship emission compliance.
In ship ballast water treatment system, to the filtration of ballast water be treatment system be substantially the most also treatment process that is most important and most critical.
Know through market survey, unit of global range Nei You 30 many enterprises is at research and development ballast water treatment system.From external product, the filter that this system is installed mainly is divided into two large classes:
1, German bohr filter is the product of main flow, formula filter element filtering of namely lighting up.Its occupation rate of market is greater than 50%.The advantage of its product is: aim at Ship's Ballast System design supporting.Have pressure reduction to control, automatic backwash technical advantage, filter area is comparatively large, volume is bigger than normal.Its inferior position is only having single filter simultaneously, and backwash is not thorough, and filter screen is perishable, easily blocks, and frequency of maintenance is high, expensive.
2, negative pressure straw cartridge filter.Its advantage is: backwash does not rely on water head-drop, and backwash effect is good.Shortcoming is: in unit volume, effective filtration area is little, and equal flow small product size is slightly large.
From the producer of domestic tens production ballast water treatment equipment, the filter dependence on import that most of producer selects.The filter usage of other form is less, and there is many problems, is mainly:
1) stable current (damage by water consumption is large) are needed;
2) single frit amount little (maximum 50-60m3/h), large discharge needs parallel combination, and volume macrostructure is complicated, and the biology close to density and water cannot be separated with impurity, there is the possibility lost efficacy.
Summary of the invention
The object of the invention is to overcome above deficiency, providing that a kind of relative volume is little, filter area is large, power consumption is little, filter efficiency is high, filtering accuracy is high, backwash effect is good, the ballast water treatment system high-precision full-automatic high-pressure backwash filter of long service life.
