Problems solved by technology

The reciprocating high-pressure pump occupies a relatively large area and body volume, and its speed is also low (the reciprocating frequency is generally less than 600 rpm); in addition, due to the high sealing requirements caused by high pressure, small maintenance is often required; and, if In order to recover and utilize the high-pressure residual energy in the seawater desalination plant, a special pressure energy recovery device is required, which has great limitations

Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] The structure of a small seawater desalination device of the present invention is as follows: figure 1 As shown, it includes a variable frequency motor 1, an electromagnetic clutch 2, a high voltage generating device 4 and an energy recovery device 3;

[0024] The energy recovery device 3 includes a turbine device, a high-pressure concentrated brine inlet 31 and a low-pressure concentrated brine outlet 32. The turbine device includes a turbine rotor. After the high-pressure liquid enters from the high-pressure concentrated brine inlet 31, it can drive the turbine rotor to rotate and from the low-pressure brine The concentrated brine is discharged at 32 outlets;

Abstract

The invention discloses a small seawater desalination pump device which comprises a variable-frequency motor, an electromagnetic clutch, a high pressure generation device and an energy recycling device. The energy recycling device is a turbine device, a turbine rotor is arranged in the turbine device, a rotary shell type high pressure pump is arranged in the high pressure generation device, and a main shaft of the variable-frequency motor, the electromagnetic clutch, the turbine rotor and a rotor of the rotary shell type high pressure pump are coaxially connected. The small seawater desalination pump device is compact in structure, and a turbine is additionally and coaxially arranged on a rotary shell pump, so that the high pressure generation device and the energy recycling device are integrated, functions are integrated, installation maintenance are easy, and besides, the small seawater desalination pump device further has the advantages that parts are not influenced mutually and axial force can be effectively balanced.

Description

technical field [0001] The invention relates to the fields of seawater desalination and high-pressure pumps, in particular to a small seawater desalination device. Background technique [0002] Our country is seriously short of fresh water resources. Seawater desalination is an effective way to solve the serious shortage of freshwater in my country's coastal areas, and it is also the most effective way for ships and island residents to solve freshwater problems. Due to the advantages of low energy consumption, no phase change process, low engineering investment, short construction period, and simple and convenient operation and maintenance, reverse osmosis seawater desalination technology has developed rapidly in recent years and has become the leading technology for seawater desalination. [0003] The multi-stage centrifugal high-pressure pump widely used in large-scale reverse osmosis seawater desalination devices is more suitable for coastal areas and large and medium-si...
