Description

The mid-filter of portable desalinization

One, technical field

The utility model relates to sea water desalting equipment, particularly for the manufacturing field of the desalinization filter of the drinking water of marine site ship's staff and coastal and the regional use in island.

Two, background technology

Along with industrialized process, in economy growing today, a more and more serious problem is placed in front of us shortage of fresh water.Each country of the whole world all is faced with so common problem, and it is particularly serious in our China, at present in state-owned more than 300 urban water shortages, 110 city serious water shortages wherein, mainly be distributed in North China, northeast and the Northwest, especially lack of water form in coastal area is very severe, coastal cities water resource of per capita major part is lower than 500 cubic metres, Dalian wherein, Tianjin, Qingdao, Lianyun Harbour, the water resource of per capita on ground such as Shanghai is lower than 200 cubic metres, belong to the serious water shortage district, according to the authoritative department statistics, the water resources ownership per capita of China only is 1/4 of world's water resources ownership per capita.Fast development along with World Economics, China's entry into the WTO and development of the West Regions, demand to water resource constantly increases all over China, particularly in the coastal open area and the Northwest, in recent years because the shortage of freshwater resources, seriously restrict industrial and agricultural production and Tourism development, influenced people's normal life.It is estimated, will reach 70-300 hundred million m3 to Chinese total water deficit in 2010, the lack of water form in above-mentioned area will be severe more.For this reason, country has started the project of South-to-North water diversion construction, remote water transfer no doubt can solve the matter of great urgency of some areas, but water transfer can not increase gross amount of water resources, and investment is more and more higher, therefore, seek a kind of material benefit more economically, effectively and the solution route with far-reaching significance become the task of top priority.

Known on the market desalinization water purifier product design structure is single, technology content is comparatively low, mainly be based on the desalination of large ship and industrial or agricultural water seawater and purification again, the purpose that reaches industrial or agricultural water and Drinking Water designs, and can not solve coastal and the regional dispersion in island water intaking family and people in the countryside seawater reach the purpose that People's Republic of China's " drinking water sanitary standard " becomes drinking water after purifying.As: Chinese patent literature disclose " a kind of marine desalination equipment " (CN200410066768.5) and " a kind of production method of desalinization " (CN00120891.8), the two all is the water source with the seawater, adopts reverse osmosis membrane filtration to be treated as Drinking Water.

Three, utility model content

The purpose of this utility model provides the mid-filter of a kind of portable desalinization, to solve the regional seawater that exceeds standard in coastal and island reaches the People's Republic of China's " drinking water sanitary standard " after purifying problem.This novel purpose is realized by following technical scheme: the mid-filter of a kind of portable desalinization, it is characterized in that, also has the micro-filtrate membrane filtration device: be provided with ring baffle in its closed container, following ring baffle, the overhead gage right side is provided with the fixedly circular card pipe of filter core, the left side is provided with the fixedly circular card pipe of filter core, the lower baffle plate right side is provided with the fixedly circular card pipe of filter core, the left side is provided with the fixedly circular card pipe of filter core, last circular card pipe can effectively be fixed two micro-filtrate membrane filtration cores with following circular card pipe by being connected overhead gage, the first micro-filtration membrane filter core, the second micro-filtration membrane filter core, first putamina, second putamina, the top of container is provided with water inlet, the back flush discharge mouth, the container lower right has delivery port on the side, and the container lower left side has the backwash water inlet, just washing floss hole; The delivery port of described micro-filtrate membrane filtration device is communicated with the water inlet of water purification jar.

In the above-mentioned design, this novel employing one-level two core filters are with at marine site ship's staff and needs coastal and the regional personnel's drinking water treatment in island.As concerning the seawater in marine site, basis is novel carries out micro-filtrate membrane filtration core filtration treatment to it.

Compare with prior art (on the basis of existing accurate filter filtration treatment), this novel pin has increased micro-filtrate membrane filtration core filtration treatment step to the water source, marine site.During this is novel, micro-filtrate membrane filtration precision height, stable effluent quality, realize manual backwash, clean efficient, thoroughly, filter screen can recover regeneration fully, the lifelong use, need not to change, backwash lasts weak point, the backwashing water consumption only is 0.001～0.002% of a normal aquifer yield, compact to design reasonable, floor space is little, be easy to carry, easy for installation, can effectively remove the silt in the water, clay, iron rust, suspension, algae, biological clay, corrosion product, big molecule bacterium, impurity such as organic matter and other molecule, reach the purpose of improving water quality, make the suitable back of water quality level filter.

This is novel to have following characteristics: 1, filtering accuracy height, water stabilization, realize backwash, clean efficiently thoroughly, filter screen can recover regeneration, the lifelong use fully, that backwash lasts is short, the backwash water consumption only is 0.001～0.002% of normal aquifer yield, compact to design rationally, floor space is little, be easy to carry.2, can effectively remove impurity such as silt in the water, clay, iron rust, suspension, algae, biological clay, corrosion product, big molecule bacterium, organic matter and other molecule, reach the purpose of improving water quality, thereby make the suitable back of water quality level filter.

This novel economizer is suitable for, good filtration effect, and water stabilization is easy to carry, and the mid-pre-filtering that is particularly suitable for desalinization is used.
