Description
Technical field
The utility model relates to a kind of water treating equipment, is a kind of reverse osmosis water treating equipment.Be a kind of low pressure reverse osmosis water treating equipment that has solar energy collector and electric heater specifically.
Background technology
Reverse osmosis is widely used in the softening desalination and the medical purified water of sea water desaltination, boiler feedwater and drinks the production of bottled water and the processing of dirty waste water as an advanced person's water technology.The operating pressure of pump is very high in the reverse osmosis system at present, usually more than 1.8Mpa, energy consumption is higher, simultaneously owing to the operating pressure height, and the pressure-bearing height of the pipeline of system, valve, drainage easily takes place in the operational process, the security and the reliability of equipment operation are lower, therefore, satisfy that equipment is exerted oneself and the condition of water quality under reduce the operating pressure of reverse osmosis, all be of great significance for security and the reliability energy-saving and cost-reducing and operation of raising equipment, this is that a kind of reality of this area is craved for.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that prior art exists, and a kind of low pressure reverse osmosis water treating equipment is provided, can satisfy that equipment is exerted oneself and the condition of water quality under reduce the operating pressure of reverse osmosis.
A kind of low pressure reverse osmosis water treating equipment of the utility model, comprise pretreatment unit, high-pressure hydraulic pump and reverse osmosis membrane assembly, it is characterized in that: between pretreatment unit and high-pressure hydraulic pump, contact successively solar energy collector and electric heater unit, the water outlet of high-pressure hydraulic pump connects reverse osmosis membrane assembly; Described electric heater unit is made of attemperater, electric heater and temperature controller, and described electric heater is arranged in the attemperater, the water temperature of temperature controller control attemperater; Connect attemperater behind the pipeline polyphone solar energy collector that is come out by pretreatment unit, the rising pipe of attemperater connects high-pressure hydraulic pump; The water temperature of attemperater is controlled at 35 ℃～45 ℃, and the operating pressure of high-pressure pump is controlled at 1Mpa～1.3Mpa.
The utility model equipment, before reverse osmosis, set up sun power and electric heater unit, improve the feed water by reverse osmosis temperature, can under the condition that does not reduce water production rate, reduce the reverse osmosis operating pressure, thereby make that the pressure-bearing of pipeline, valve of system is less, lower to the material requirement of withstand voltage, can reduce equipment degree manufacturing cost and reduce drainage in the equipment running process.
Description of drawings
Fig. 1, be the pipeline structure synoptic diagram of a kind of low pressure reverse osmosis water treating equipment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of low pressure reverse osmosis water treating equipment, this device comprises pretreatment unit 1, solar energy collector 2, electric heater 3, attemperater 4, temperature control unit 5, high-pressure pump 6, reverse osmosis membrane assembly 7.Wherein pretreatment unit 1 is a prior art, comprise more medium filter, charcoal absorption strainer and accurate filter, the rising pipe of pretreatment unit 1 is connected with the water inlet pipe of solar energy collector 2, the rising pipe of solar energy collector 2 is connected with attemperater 4, be provided with electric heater 3 and temperature control unit 5 in the attemperater 4, the water outlet of attemperater 4 is connected with the water-in of high-pressure pump, and the water outlet of high-pressure pump is connected with reverse osmosis membrane assembly.In the operational process, the water temperature of attemperater is controlled at 35 ℃-45 ℃, and the operating pressure of high-pressure pump is controlled between 1Mpa～1.3Mpa.Described electric heater is only as assisted heating device, is not enough to enable when temperature with attemperater is heated to 35 ℃～45 ℃ at solar energy collector, in case reach this temperature range, temperature control unit control electric heater automatically stop heating.The used reverse osmosis membrane of reverse osmosis membrane assembly can adopt LG-DOW (DOW) TW30 type reverse osmosis membrane, also can adopt the reverse osmosis membrane of other manufacturers produce.Adopt this device, 35 ℃ of control attemperater water temperatures, the operating pressure of pump can be reduced to 1.30Mpa from 1.80Mpa (water temperature is 25 ℃) during water production rate 450L/h, the attemperater water temperature is brought up to 40 ℃, the operating pressure of pump further drops to 1.15Mpa, the attemperater water temperature is brought up to 45 ℃, and the operating pressure of pump can drop to 15Mpa.
The utility model utilizes sun power and electric energy to improve the inflow temperature of reverse osmosis membrane, reduces reverse osmosis operating pressure (less than 1.3Mpa) under the condition that does not reduce water production rate, reduces power consumption; Simultaneously because the reduction of operating pressure, the pipeline of system, the pressure-bearing of valve are less, lower to the material requirement of withstand voltage, thereby can reduce the possibility that drainage takes place in equipment degree manufacturing cost and the equipment running process, the security and the reliability of the operation of raising equipment.In addition, because Heating temperature is not high, required solar energy collector is less, and the electric heater energy consumption is also lower, and membrane module can be used polytype reverse osmosis membranes such as rolled film, tubular fibre formula, and the water pump in the system can guarantee the equipment round-the-clock running.Therefore, the present invention is with the obvious advantage, and the difficulty of enforcement is less, not only can be used for new reverse osmosis equipment, also can have application potential widely to existing reverse osmosis equipment transformation.
