Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, a kind of water cleaning systems with backwashing function that the present embodiment proposes, including be sequentially connected
Raw water box 1, raw water pump 2, quartz filter 3, active carbon filter 4, cartridge filter 5, RO membrane modules 6 and RO abacterial water tanks
7.The water inlet of raw water box 1 is provided with water compensating valve 8, and the upper end of raw water box 1 is provided with the first liquid level sensor 9, and the parallel connection of raw water pump 2 is set
Two are put, a conduct is standby.The water inlet of quartz filter 3 is provided with the first control valve 10, for controlling quartz sand filtration
The backwash of device 3 and water is normally produced, the water inlet of active carbon filter 4 is provided with the second control valve 11, for controlling activated carbon to filter
4 backwashes of device and normally produce water.Chemicals dosing plant 12, chemicals dosing plant 12 are installed between active carbon filter 4 and cartridge filter 5
Including dosing tank 13 and measuring pump 14.RO membrane modules 6 include two section 16 of one section 15 of RO films and RO films, one section 15 of the RO films and institute
State RO films to be connected in series for two section 16, one section of 15 entrance of RO films is provided with RO high-pressure pumps 17, one section of 15 entrance of RO films and RO films two
16 exits of section are respectively equipped with first pressure meter 18 and second pressure meter 19.The upper end of RO abacterial water tanks 7 is provided with the second liquid level
Sensor 20.And sensor, pressure gauge, control valve and the pump housing all in system is connected with switch board, due to switch board skill
Art is relatively conventional, therefore will not be repeated here.
The system is provided with quartz filter and active carbon filter backwashing function, concrete operations are as follows：
First control valve of quartz filter is placed in backwash position, has water and water compensating valve in raw water box after confirmation is errorless
In the case of door is opened, while start 2 raw water pumps and rinse quartz sand filter leaching material.Water inlet starts rear first few minutes, it is necessary to head
Water is first full of whole tank body, so the anhydrous discharge of sewage draining exit, but have air and extruded from tank body.After tank body water outlet, backwash is extremely
Switching control valve to position is just washed to clean outlet (1 raw water pump can be closed by just washing journey), control by switching again after clean outlet
Valve processed to backwash position continues to rinse (during backwash 2 raw water pumps while open), so circulation until backwash and positive wash-off water without
Untill naked eyes impurity is discharged, complete quartz filter and rinse；
First control valve of quartz filter is switched to production water position, the second control valve of active carbon filter is placed in
Backwash position, raw water pump flushing active carbon filter filtrate, the same quartz sand of operating method are opened in the case where raw water box has water
Filter rinses (only open 1 raw water pump), after the completion of close raw water pump, control valve is switched to production water position.
Certain density antisludging agent is added in chemicals dosing plant, is added into the raw water before RO membrane modules.Antisludging agent
Addition concentration is 3-5PPM, and the system takes median 4PPM to add, and antisludging agent dosing tank can about be used with the device medicament of 5 days
Amount, new antisludging agent must be configured before having used and supplies equipment production and application.
After a certain time of operation, the meeting of RO membrane modules decays, it is necessary to logical the system because of the reason such as dirty stifled or fouling
Cross Chemical cleaning and recover or improve its performance.And judge whether to need to clean the then standardization pressure according to RO membrane modules inlet and outlet
Difference, rise 15% when standardizing pressure difference between water inlet and concentrated water, or standardization aquifer yield reduces by 10%, illustrate RO films by it is biological,
Organic matter or colloid etc. pollute；Or substantially reduced when producing water, but the pressure difference between concentrated water of intaking rises without obvious, illustrates RO film tables
Face deposits inorganic salt crust；Or during standard salt dissolving transmitance increase by 5%, it should which RO membranous systems are cleaned.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, is not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
