Abstract

An eddy current sea water desalting system for ships relates to a sea water desalting system. In the eddy current sea water desalting system for ship, a sea water intake is sequentially connected with a silt separator, an engine cooler for ship, a integrated filter, a UF filter, the first high pressure pump, a flow control valve, an NF filter and a pure water storage can. The NF filter is sequentially connected with the second high pressure pump, the flow control valve, a RO filter, a direct-drinking water storage can. The eddy current sea water desalting system for ship is a sea water desalting equipment employing the reverse osmosis technology, nanofiltration technology, eddy shedding principle and integrated filter. No moveable component is arranged in the silt separator, making the silt separator need not to be maintained. The filter element of the integrated filter can be repeatedly cleaned and regenerated without needing to be changed, which reduces the dirty and blocking phenomena. The engine cooler makes the eddy current sea water desalting system of the utility model have higher working efficiency.

For solving the above problems, the utility model provides a kind of do not need often to safeguard and can the reduce dirt of filter screen, the eddy current seawater desalination system peculiar to vessel of stifled phenomenon.

Eddy current seawater desalination system peculiar to vessel, comprise seawater water inlet, UF filter, controller, pressure-gradient control valve, pressure sensor, first high pressure pump, flow-controlling gate, water purification water storing tank, second high pressure pump, RO filter, silt blowoff valve, wastewater outlet, also comprise silt disconnector, integrated filter, marine engine cooling vessel, NF filter, direct drinking water storing tank; The water inlet of silt disconnector connects the seawater water inlet, the water outlet of silt disconnector separation of sediment connects the silt blowoff valve, the other end of silt blowoff valve connects wastewater outlet, the water outlet that the silt disconnector separates clear water connects the marine engine cooling vessel, the other end of engine cooling apparatus connects integrated filter, the condensed water outlet of integrated filter connects the silt blowoff valve, the drainage outlet of integrated filter connects the UF filter, the water outlet that the UF filter filters out waste water connects the silt blowoff valve, the water outlet of the clear water after the filtration connects first high pressure pump, the first high pressure pump connection traffic control cock, flow-controlling gate connects the NF filter, the wastewater effluent mouth of NF filter connects pressure-gradient control valve, be equipped with pressure sensor on the pressure-gradient control valve, the other end of pressure-gradient control valve connects integrated filter, the clear water water outlet of NF filter connects the water purification water storing tank, the clear water water outlet of NF filter also is connected with second high pressure pump, the second high pressure pump connection traffic control cock, flow-controlling gate connects the RO filter, the wastewater effluent mouth of RO filter connects pressure-gradient control valve, be equipped with pressure sensor on the pressure-gradient control valve, the other end of pressure-gradient control valve connects the silt disconnector, and the clear water water outlet of RO filter connects the direct drinking water storing tank.

Described integrated filter, comprise water inlet, filtered water outlet, housing, coarse filter element, smart filter core, microstraining core, condensed water outlet, there is a water inlet housing upper end, there is a condensed water outlet lower end, there is a filtered water outlet side, the enclosure interior outermost layer is a coarse filter element, the second layer is smart filter core, the innermost layer is a microstraining core, three metafiltration cores all are ring-type, communicate between water inlet and three metafiltration cores and the housing, communicate between condensed water outlet and three metafiltration cores and the housing, filtered water outlet and microstraining core inside communicate.

The utility model has the advantages that: the silt disconnector, utilize vortex principle that the suspended matter in the seawater, compound are separated because inside does not have movable part, need not safeguard; Integrated filter, inner integrated multilevel filter core, and filter core cleaning and regeneration repeatedly need not changed all the life, moreover filter screen are carried out automated washing filter process the time, greatly reduce the dirt of filter screen, stifled phenomenon; Ultra filtration filter (UF filter) is security personnel's filters in addition, and newly-increased one-level nanofiltration filter (NF filter), the pressure that needs because of the NF membrane of unidimensional specification be well below reverse osmosis membrane, and producing water ratio height, cost are low, form two-stage and produce water; The clear water that separates through the silt disconnector enters the marine engine cooling vessel, carry out energy replacement, the heat that absorbs driving engine improves the temperature of handling water, utilize the engine cooling apparatus of boats and ships itself that filtered water is heated, make this device have higher work efficiency, and can alleviate the situation of the fouling of cooling vessel; Since used NF filter and RO filter and two independently water storing tank make a table apparatus can work as two to do the use of platform machine.

Description of drawings:

Fig. 1 is a constructional drawing of the present utility model;

Fig. 2 is the constructional drawing of integrated filter among Fig. 1.

The specific embodiment:

As Fig. 1, the seawater that sea water pump 2 is extracted out from seawater water inlet 5 enters silt disconnector 7, utilize vortex principle, make current produce the anticlockwise direction rotation by silt disconnector 7 in-to-in air deflectors, because the high speed revolution of current, make the different material of quality produce different centripetal force, the silt in the water is separated, the silt of discharge is discharged through silt blowoff valve 6, wastewater outlet 4.Clear water enters marine engine cooling vessel 8, carry out energy replacement, the heat of absorption driving engine becomes the warm water about 30 ℃, enter into integrated filter 9 again, as Fig. 2, water inlet 30, condensed water outlet 35 and filtered water outlet 38 are arranged on the housing 31 of described integrated filter 9, and there are coarse filter element 34, smart filter core 33, microstraining core 32 multi-stage filter cores in inside.When seawater stream enters in the housing 31 by water inlet 30, filtration through filter core is divided into two strands, vertically current 36 and lateral current 37, lateral current 37 by filter element filtering after filtration water out 38 flow out, vertically 36 in current are being with and are being leached thing and directly export 35 discharge orifices by condensed water.Discharge through silt blowoff valve 6, wastewater outlet 4 from the non-filtered water that condensed water outlet 35 is discharged, the filtered water that flow out from drainage outlet 38 enter the UF filter 10 purifies.The water of Ti Chuning is not discharged through silt blowoff valve 6, wastewater outlet 4, and the water after the purification is pumped in the NF filter 15 by first high pressure pump 13.Water wasting through NF filter 15 flows out enters into integrated filter 9 by pressure-gradient control valve 11.A pressure sensor 12 is arranged on pressure-gradient control valve 11,, utilize controller 1 to come dominant discharge control cock 14 according to pressure sensor 12 detected pressure, thus dominant discharge.Water part after NF filter 15 filters enters into water purification water storing tank 26, and another part water is pumped in the RO filter 22 by second high pressure pump 25, and the water of the non-filtration of flowing out from RO filter 22 enters into silt disconnector 6 by pressure-gradient control valve 23.A pressure sensor 21 is arranged on pressure-gradient control valve 23,, utilize controller 1 to come dominant discharge control cock 24 according to pressure sensor 21 detected pressure, thus dominant discharge.Water after RO filter 22 filters enters into direct drinking water storing tank 20.
