Description

A desalination system with a combined high-pressure pump

technical field

The utility model relates to a desalination system with a combined high-pressure pump.

Background technique

In the complete reverse osmosis system, one of the important parts is the high-pressure pump system. At present, most of the medium and large-scale systems for reverse osmosis brackish water desalination and seawater desalination use a single high-pressure plunger pump with relatively large flow and lift. The plunger pump is also relatively large, bulky, and inconvenient to carry. In practical applications, it still has a long growth cycle, relatively expensive prices, and difficult maintenance and repair; A single high-pressure plunger pump is risky. Once a single high-pressure plunger pump fails, the entire desalination system will stop running and the work will be unstable.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a desalination system with a combined high-pressure pump that has a short production cycle, convenient maintenance, low cost and stable operation.

The technical solution adopted by the utility model is: the utility model includes a water supply pump, a pretreatment device, and a reverse osmosis membrane assembly, and the desalination system with a combined high-pressure pump also includes a high-pressure device, and the water supply pump, pretreatment The reverse osmosis membrane module of the device and the high pressure device are connected in sequence, and the high pressure device is composed of at least two high pressure pumps connected in parallel, and the reverse osmosis membrane module is respectively connected with a pure water port and a concentrated water port.

A sterilizing device is also provided between the water supply pump and the pretreatment device.

The pretreatment device includes a primary filter device, and the primary filter device includes a multimedia filter and an activated carbon filter connected in sequence.

The pretreatment device also includes a secondary filter device, and the secondary filter device includes a precision filter and a security filter connected in sequence.

The beneficial effects of the utility model are: in the utility model, a plurality of small high-pressure plunger pumps are used to replace large-scale high-pressure plunger pumps. The price is cheaper than a single large high-pressure plunger pump, and the cost performance is high. Using multiple high-pressure plunger pumps is also easier to control in terms of electrical control, and reduces the starting power of the entire system, reduces the configuration of the electrical system, and saves electrical appliances. component cost.
