Description

A kind of water treatment reverse osmosis device

Technical field

The utility model relates to water treatment device, particularly relates to a kind of water treatment reverse osmosis device.

Background technology

Along with the continuous expansion of ignition group of motors construction scale, parameter and the capacity of unit improve constantly, and deep change is also just occurring in power plant chemistry water treatment.And the power of this change, be mainly derived from the requirement of high-parameters large sized unit to water quality and the needs of environment protection, new water technology and the appearance of material and apply again for the development of water treatment of power plant technology provides possibility.The wastewater treatment in existing power station can adopt reverse osmosis system usually, and utilize reverse osmosis system process to obtain dense water, dense water arranges waste treatment outward, causes the waste of the energy while contaminate environment.

Utility model content

The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of water treatment reverse osmosis device is provided, discharge after solving the dense water of anti-penetration wastewater disposal traditional in current technology, the problem wasted energy while contaminate environment.

For solving above technical problem, the technical solution of the utility model is:

A kind of water treatment reverse osmosis device, comprise reverse osmosis module, it is characterized in that, described reverse osmosis module comprises one section of reverse osmosis module and two sections of reverse osmosis modules, one section of reverse osmosis module is connected with two sections of reverse osmosis modules, the dense water that the process of one section of reverse osmosis module obtains obtains pure water after the process of one section of reverse osmosis module, and the film group number of one section of reverse osmosis module is greater than the film group number of two sections of reverse osmosis modules.Water treatment reverse osmosis device described in the utility model adopts two-section type to arrange, two-section type process is carried out to obtaining the former water of waste water in production, the water inlet of one section of reverse osmosis module is the former water that high-pressure pump pressurization is injected, and the water inlet of two sections of reverse osmosis modules is the dense water obtained after the process of one section of reverse osmosis module.When adopting reverse osmosis membrane to carry out water treatment, it is more much smaller than flooding quantity that the water yield obtained is processed in infiltration, if therefore one section of reverse osmosis module is set to equal with the module quantity of two sections of reverse osmosis modules, then can the processing power of guide rail two sections of reverse osmosis modules superfluous, the water yield of the dense water obtained after the process of one section of reverse osmosis module is less, dense water can not meet two sections of reverse osmosis modules completely and process at full capacity, waste resource, pure water is also caused to yield poorly, therefore the film group number that the utility model arranges one section of reverse osmosis module is greater than the film group number of two sections of reverse osmosis modules, the water yield of the dense water obtained after making the process of one section of reverse osmosis module increases the processing power meeting two sections of reverse osmosis modules.

Further, the ratio of the film group number of one section of described reverse osmosis module and the film group number of two sections of reverse osmosis modules is 3:1.The water yield of the dense water that former water obtains after the process of one section of reverse osmosis module is roughly 1/3rd of former water, therefore the film group number of one section of reverse osmosis module and two sections of reverse osmosis modules is set to 3:1, one section of reverse osmosis module and two sections of reverse osmosis modules can be made to process at full capacity simultaneously, avoid the wasting of resources, improve water production rate.

Further, the inside module of one section of described reverse osmosis module adopts structure in parallel, the former water of parallel processing, improves processing efficiency.

Further, the reverse osmosis membrane aperture of one section of described reverse osmosis module is 0.3 ~ 0.5nm, and during filtration, extracting solution temperature is 20 ~ 40 DEG C, is 1.05 ~ 1.15MPa to hydraulic pressure.

Further, the reverse osmosis membrane aperture of two sections of described reverse osmosis modules is 0.1 ~ 0.3nm, and during filtration, extracting solution temperature is 20 ~ 40 DEG C, is 0.95 ~ 1.05MPa to hydraulic pressure.

Compared with prior art, the utility model advantage is:

Water treatment reverse osmosis device described in the utility model carries out two stage process to waste water, reduces concentrated water discharge, and obtained pure water is recycled, and improves pure water output, reduces the wasting of resources, reduces environmental pollution; Pure water output 11-12 ton after transformation/hour, existing concentrated water drainage high-volume than original reduce 2-3 ton/little time, every day, water production rate was by 180 tons, water time shorten 7-9 hour is produced after transformation, every day, save power was 350kwh, and electricity price, by 0.5 yuan/kwh, can be reduced expenses 175 yuan every day.
