Utility model content

Technical problem to be solved in the utility model is to provide a kind of accurate automatic plus alum control of stable, controlSystem.

To solve the technical scheme that above-mentioned technical problem is used：It is a kind of to add alum control system automatically, including with alum tank, storageAlum tank, quantitatively plus alum pipeline, variable add alum pipeline, raw water pipeline, pipe-line mixer, reaction settling basin and control rack, it is describedQuantitatively plus alum pipeline and variable add alum pipeline to be arranged in parallel and two is corresponding respectively is connected with storage alum tank, raw water pipeline, instituteState raw water pipeline and be provided with the flowmeter being electrically connected with control rack, quantitatively plus on alum pipeline be sequentially provided with quantitatively describedPump, ripple damper, pressure gauge and counterbalance valve, add in the variable and variable pump, ripple damper, pressure are sequentially provided with alum pipelinePower table and counterbalance valve, the constant displacement pump and variable pump are electrically connected with control rack respectively, the raw water pipeline, pipeline mixingDevice, reaction settling basin are sequentially connected and connect, and the reaction settling basin is connected with the transmissometer being electrically connected with control rack.

Further, it is described quantitatively plus alum pipeline and variable to add and be also respectively connected with bursting tube between alum pipeline and storage alum tankRoad, safety valve is provided with the safety line.

Further, the liquid level gauge being electrically connected with control rack is provided with the storage alum tank.

Beneficial effect：This is automatically plus in alum control system, using quantitatively plus alum pipeline and variable add alum pipeline to be arranged in parallel,Pair plus alum amount be controlled, quantitatively plus alum pipeline use and quantitatively controls to meet minimum alum liquid demand, variable add alum pipeline byControl rack real-time regulation is controlled and conveys a certain amount of alum liquid according to actual conditions, to cause that it is optimal that alum liquid and raw water reachMixed proportion, so that throwing alum amount is more accurate, effectively save water purification cost.

Brief description of the drawings

The utility model is described further with reference to the accompanying drawings and examples；

Fig. 1 is the systematic schematic diagram of the utility model embodiment.

Specific embodiment

Reference picture 1, the utility model is a kind of automatically plus alum control system, including with alum tank 1, storage alum tank 2, quantitatively plus alum pipeRoad 4, variable adds alum pipeline 5, raw water pipeline 6, pipe-line mixer 7, reaction settling basin 8 and control rack 9, quantitatively adds alum pipeline 4Be arranged in parallel with variable plus alum pipeline 5 and two respectively it is corresponding with storage alum tank 2, raw water pipeline 6 be connected, on raw water pipeline 6The flowmeter 61 being electrically connected with control rack 9 is provided with, quantitatively plus on alum pipeline 4 constant displacement pump 41, damping of pulsation is being sequentially provided withDevice, pressure gauge and counterbalance valve, variable pump 51, ripple damper, pressure gauge and back pressure are sequentially provided with variable plus alum pipeline 5Valve, constant displacement pump 41 and variable pump 51 are electrically connected with control rack 9 respectively, raw water pipeline 6, pipe-line mixer 7, reaction settling basin8 are sequentially connected and connect, and reaction settling basin 8 is connected with the transmissometer 81 being electrically connected with control rack 9.

In the present embodiment, raw water enters pipe-line mixer 7 from raw water pipeline 6, and flowmeter 61 is detected to raw water flowAnd in feeding back to control rack 9,81 pairs of processes of transmissometer add the water that alum is processed to carry out Turbidity measurement, and will detection numeric feedback extremelyControl rack.Wherein, the liquid level gauge being electrically connected with control rack is provided with storage alum tank 2, liquid level gauge is anti-by alum liquid capacity informationIt is fed to control rack 9.Quantitatively plus alum pipeline 4 quantitatively conveys alum liquid, variable adds alum pipeline 5 to be controlled by the real-time regulation of control rack 9And a certain amount of alum liquid is conveyed according to actual conditions, to cause that alum liquid and raw water reach optimal mixed proportion, quantitatively add alum pipeRoad 4 and variable add alum pipeline 5 to be arranged in parallel, and quantitatively add alum pipeline 4 to use and quantitatively control to meet minimum alum liquid demand, variablePlus alum pipeline 5 uses Variable Control, according to raw water flow and Turbidity measurement feedback real-time regulation control plus alum amount so that throw alum amountIt is more accurate, effectively save water purification cost.

Preferably, quantitatively adding alum pipeline 4 and variable to add between alum pipeline 5 and storage alum tank 2 has been also respectively connected with bursting tubeRoad 10, is provided with safety valve 11 in safety line 10.

Implementation method of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited toImplementation method is stated, in the ken that the technical field those of ordinary skill possesses, this practicality can also not departed fromVarious changes can be made on the premise of new objective.
