Abstract

The utility model relates to an improved seawater desalinating apparatus, which comprises a machine frame used for fixing and installing the apparatus. A motor and a reverse osmosis membrane are arranged in the machine frame. In order to reduce the volume of the desalinating apparatus, the utility model discards a traditional multistage sand filtration drug adding filtration treatment device which is replaced by a core filtration type filter with good filtration effect, small volume and light weight instead, and the utility model adopts multiple stages, usually three stages or more than three stages. Meanwhile, in order to further reduce the volume and decrease the weight, the driving system of a belt or a gear wheel class is also spared. The utility model adopts the driving mode of the direct connection of an output shaft of the motor with the input end of a plunger pump. The utility model has small volume, light weight and portability, and is suitable for flowing use on ships and on the sea.

Description

Improved sea water desalinating plant

Technical field

The utility model relates to a kind of improved sea water desalinating plant, and particularly a kind of have particular requirement for being suitable for naval vessels etc. to volume, the weight of sea water desalinating plant, and improved sea water desalinating plant.

Background technology

For some more special sea water desaltination application scenario, on narrow and small relatively naval vessel, living space, wish that desalting equipment should take as far as possible little usage space, and offshore surveys etc. have mobile big characteristics, wish simultaneously that again desalting equipment answers volume little and in light weight, so that carry.

Seawater contains suspended substances such as bacterium, algae, protista, silt, also contain macromolecular compound, colloidal sol isocolloid and salt dvielement, for making it reach drinking water standard, existing multiple desalination method and corresponding apparatus are as distillation method, ion exchange method, electroosmose process, cold method and reverse osmosis method.

Distillation method needs heating installation, and volume is therefore and huge, and the fresh water that ion exchange method and electroosmose process are produced is not used in usually and drinks, and the cold method power consumption is high.Reverse osmosis method has the advantages that energy consumption is low, desalination water is of fine quality, it is the desalination method that extensively adopts at present, desalting plant according to this method principle of tool adopts secondary sand-bed filter, one-level doser, reverse osmosis membrane with sea water desaltination usually, and be provided with high-pressure pump in the reverse osmosis membrane prime, under high pressure conditions, the seawater shunting formed fresh water.But the prime that sand-bed filter and doser are formed filtration volume is bigger, and weight is also high, also has, and high-pressure pump makes also that because of linking to each other with power set by power train the volume of desalting equipment is bigger.

Summary of the invention

The purpose of this utility model provide a kind of volume little, in light weight, be suitable for flow using, improved sea water desalinating plant.

The improved sea water desalinating plant that provides, comprise a frame that is used for fixing erecting equipment, motor of frame internal fixing, a reverse osmosis membrane, for making the desalting equipment volume-diminished, the utility model has been abandoned traditional multistage sand filtration dosing filtration treatment device, the substitute is, adopt good, the little lightweight filer element type strainer of volume of filter effect, and adopt multistagely, be generally more than three grades or three grades.Simultaneously, reduce weight, also saved the power train of belt or gear class, adopt the output shaft of motor and the direct-connected type of drive of input terminus of ram pump for further reducing volume.

Description of drawings

Fig. 1 is a fundamental diagram of the present utility model;

Fig. 2 is the general assembly structure iron of the utility model most preferred embodiment;

Fig. 3 is the left view of Fig. 2.

Below in conjunction with accompanying drawing and most preferred embodiment to being described further.

Embodiment

Principle of work of the present utility model as shown in Figure 1, seawater is under the effect of ram pump 2, seawater inlet 6 from desalting equipment enters, enter reverse osmosis membrane 7 through first step filer element type strainer 5, second stage filer element type strainer 4, third stage filer element type strainer 3, confess at water outlet 9 at last, dense water is discharged from dense water out 8, and 1 in motor directly links to each other with ram pump 2 power intakes.

Most preferred embodiment of the present utility model is referring to Fig. 2 and Fig. 3, frame 10 adopts stainless steel to make, there is an instrument case 101 in Fig. 2 left side, be furnished with instrument 103, button 102 etc. on its panel, be used for the operation and the monitoring of device, four dismountable universal travel wheels 104 also are equipped with in the bottom of frame 10, are used for the push-and-pull walking.Motor 1 is fixed on the bottom of frame 10, ram pump 2 is fixed on motor 1 axle head, 4,3 reversals of the natural order of things of second and third grade filer element type strainer are installed in the top of frame 10, and first step filer element type strainer 5 is positioned at the rear portion of second stage filer element type strainer 4 in Fig. 2, invisible in Fig. 2.Reverse osmosis membrane 7 also hangs upside down the top that is fixed on frame 10, the hose connection discharge outlet of dense water out 8 and water outlet 9 usefulness to frame 10, and seawater inlet 6 also is arranged on the frame 10.Owing to saved traditional power train, and adopted little, the in light weight filer element type strainer of volume with precision Filter element, the precision of three grades of filer element type filter elements is followed successively by 15 μ m, 5 μ m and 1 μ m from low to high, 0.2 cubic metre of the maximum gabarit volume of present embodiment less than, 20 kilograms of under weight.

The foregoing description only is used for the understanding to the present utility model design, is not to restriction of the present utility model, under the guidance of the utility model design, many simple variations also can be arranged, for example, plastics or stainless steel can be installed outside frame 10 cover plate, internal unit is protected.
