Abstract
The utility model discloses a water treatment unit using adsorption method for fluoride removal, particularly suitable for taking activated alumina as adsorbing agent. The water treatment unit comprises a pipe system which automatically adjusts the raw water pH value and regeneration alkali liquor pH value with raw water pressure. In pipes, fluid technology is adopted to extract acid and alkali liquor to adjust the pH value.
Description
Affiliated technical field:
The utility model belongs to the absorption method fluorine removal device.
The utility model design background:
Adopt activated alumina to make de-fluoridation adsorbent, experimental results show that and to control former water ph value, will make loading capacity remain on optimum value, for example reach 12.5mg/g.Control the practice of former water ph value in the water factory of central water supply, external report has State of Arizona, US Ji Naxide city daily output water 2.8 * 10
3m
3The water factory of/day.But according to China's situation, well water is drunk in a lot of water of high fluorine content areas, generally is to disperse to supply water.And at present in small-sized removal of fluorine from water device, not about utilizing former water pressure to control the report of former water ph value.
The utility model purpose of design:
The design's purpose is to make the absorption method fluorine removal device that a kind of pressure that can utilize former water itself is adjusted pH value automatically.
The utility model content:
The design's content comprises defluorination and regeneration two big piping systems.Pipeline structure as shown in drawings.
The flow direction of defluorination pipeline is that former water is entered by the pipe valve 11a that discharges water, by the pipeline of four-way pipe fitting 12 along cock 1a control, and through water sprayer 3a, tee pipe fitting 13, cock 1b enters from adsorption-defluorination post 9 bottoms, flow out at the top is that defluorination disposes.Suspended body flowmeter 5a shows the defluorination filtering velocity, and the pipe valve 11b that discharges water emits the water purification of handling.Connect water purification fluorine content monitoring pipeline, water sampling monitoring at any time through cock 1g.
The flow direction of regeneration pipeline is former water through the pipeline of four-way along cock 1c control, enters the storage alkali jar 8 that level attitude is higher than defluorination post 9 through water sprayer 3b.Close pipe valve 11b and cock 1g, 1b when treating defluorination post 9 internal adsorption agent regeneration, open cock 1d alkali lye and enter from adsorption column 9 tops, the pipe valve 11c that flows through from the bottom discharges.
The design is characterised in that:
In the defluorination pipeline, former water utilizes former water pressure to sneak into an amount of diluted acid to adjust former water ph value for power through water sprayer before entering adsorption-defluorination post 9.
In the regeneration pipeline, former water enters storage alkali jar 8 is allocated required pH value before with above-mentioned principle and device regeneration alkali lye.
Like this, under the constant situation of former water pressure value and raw water quality, the control filtering velocity just can keep former glassware for drinking water that required stable pH value is arranged.Can control regeneration alkali lye pH value equally.
Finish the additional unit and the connecting pipeline thereof of above-mentioned design function, also indicate in the accompanying drawings.
Transfer the additional line flow direction of former water ph value part to be: former water is through cock 1a, water sprayer 3a, because jet action, the diluted acid in the extracting storage alkali jar 6 makes it to be dissolved in the former water that flows to adsorption column 9, the extracting amount of diluted acid can be shown by suspended body flowmeter 5b, and control with check valve 2a.Check valve 2a can prevent that former aqueous reflux is to the diluted acid basin simultaneously.Former water ph value can adopt and draw former water and count 10 places through cock 1f to PH and measure.For in diluted acid basin 6, adding diluted acid, utilize the additional storage diluted acid pipeline of former water pressure, its flow direction be former water through cock 1e water sprayer 3c because jet action, the concentrated acid in the extracting concentrated acid jar 4, being diluted in former water in the pipeline becomes diluted acid and stores into diluted acid basin 6.The check valve 2b control concentrated acid amount of dissolving in also prevents that former aqueous reflux from going into concentrated acid jar 4.
Transfer the additional line of regeneration alkali lye to flow to be former water through cock 1e, water sprayer 3b, utilize jet action, the extracting high alkali liquid is miscible from concentrated base jar 7 becomes sig water in Yuan Shui to enter regeneration alkali lye basin 8 standby.The concentrated base amount is joined in check valve 2c control, also prevents that former aqueous reflux from going into concentrated base jar 7 simultaneously.
The enforcement of utility model
Capacity and quantity that the design can dispose defluorination post 9 in force according to the needs of service discharge guarantee continuous water supply as palpus.At least want two posts of configuration in parallel,, can use another to handle former water so that during a regeneration.All the other additional line only need a cover to get final product.
Can form and to have for bringing into play the design that standardized of same function bonded annex various according to present design by cock 1f, the former water ph value monitoring device that PH meter 10 and connecting pipeline constitute, the former water ph value device of accent that constitutes by water sprayer 3a, suspended body flowmeter 5b, check valve 2a, diluted acid basin 6 and connecting pipeline; The complex acid device that constitutes by cock 1e, water sprayer 3c, check valve 2b, concentrated acid basin 4 and connecting pipeline; Elevated regeneration alkali lye basin 8 reaches by the cock 1c that connects the standardized product of all size that the processing water yield of joining the alkali device that water sprayer 3b check valve 2c, concentrated base basin 7 and connecting pipeline constitute is different on former water branch pipeline.
The advantage of utility model
The design is applicable to that former water has certain pressure, and the water unit that gets final product such as tap water pressure settles processing high-fluorine water water voluntarily. Complex acid is transferred former water ph value and is joined alkaline regeneration solution and all utilize former water pressure automatically to carry out, and does not add in addition power. Easy to operate, operating cost is cheap.
