Description
Technical field
The utility model relates to a kind of process water treatment system, and particularly a kind of vitriol works process water supernatant treatment system, belongs to chemical technology field.
Background technology
Chemical fertilizer industry factory needs to use a large amount of clear water aborning, is usually applicable to drawing from neighbouring surface drainage system directly carrying out production application afterwards according to production requirement.Often happened suddenly in summer storm flood, and surface drainage system turbidity increases about 2000mg/L, increases the pressure load for dirty water of water pump and chemical production equipment, and usually cause production product cannot meet relevant criterion requirement because water source turbidity exceeds standard.
Utility model content
Goal of the invention of the present utility model is: cause production unit pressure load to increase for the increase of prior art industrial land table water system turbidity, affect the problem of product quality, provide a kind of vitriol works process water supernatant treatment system.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of vitriol works process water supernatant treatment system, being supplied to production plant for drawing water from river, comprising the first settling pool, the second settling pool, the 3rd settling pool, water pump, frequency transformer, automatic feeder.
The inlet channel of described water pump is arranged in river, and described water pump is connected with frequency transformer, to be drawn water speed by Frequency Converter Control water pump.
The outlet conduit of described water pump is connected in the first settling pool.Described first settling pool, the second settling pool, the 3rd settling pool are disposed adjacent, and the first settling pool overflow port is towards the second settling pool, and the second settling pool overflow outlet is towards the 3rd settling pool, and the clear water in the 3rd settling pool is directly utilized by production plant.
Described automatic feeder is arranged on by the first settling pool, and automatic feeder discharge port is connected on the first settling pool.
The utility model sets up frequency transformer makes its water withdrawal reach steadily quantitatively, is being provided with multistage settling pool by overflow supernatant, is making the clear water in the 3rd settling pool meet production plant service requirements.Even if in the flood season, also river turbidity can be reduced to 20-70mg/L by original 2000mg/L, meet production requirement.
As preferred version of the present utility model, in described automatic feeder, store flocculation agent, and can quantitatively throw in by self-timing.Described flocculation agent is aluminium chlorohydroxide.Aluminium chlorohydroxide can well adsorption precipitation except the suspended impurity in anhydrating, improve the clarity of river.
in sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, by Frequency Converter Control water pump operating rate, the matching degree of pump-out and water of productive use amount in water pump working time is improved, power cost saving.
2, by multi stage precipitation and flocculation adsorption process, effectively improve production water quality, improve product quality, slow down equipment Ordinary Wear and Tear speed.
Accompanying drawing explanation
Fig. 1 is the utility model.
Mark in figure: 1-first settling pool, 2-second settling pool, 3-the 3rd settling pool, 4-water pump, 5-frequency transformer, 6-automatic feeder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Vitriol works's process water supernatant treatment system as shown in Figure 1, comprises the first settling pool 1, second settling pool 2, the 3rd settling pool 3, water pump 4, frequency transformer 5, automatic feeder 6.The inlet channel of described water pump 4 is arranged in river, and described water pump 4 is connected with frequency transformer 5, controls water pump 4 and to draw water speed, make it to match with water of productive use amount by frequency transformer 5.The outlet conduit of described water pump 4 is arranged in the first settling pool 1, first settling pool 1, second settling pool 1, the 3rd settling pool 3 are disposed adjacent, water in first settling pool 1 overflows to the second settling pool 2, water in second settling pool 2 overflows to the 3rd settling pool 3, clear water turbidity in 3rd settling pool 3 is reduced to minimum level, meet aquatic products requirement, directly used by production plant.Described automatic feeder 6 is arranged on the first settling pool other 1, and automatic feeder discharge port is connected on the first settling pool.Because frequency transformer installed by water pump, water withdrawal more steadily quantitatively, has effectively saved grid electricity fee cost.Meanwhile, the first settling pool 1, second settling pool 1, the 3rd settling pool 3 cut off body of wall by the choked flow arranged and realize multistage overflow sedimentation blowdown process.Water of productive use turbidity is reduced greatly, improves the product quality such as company's phosphoric acid, sulfuric acid, hydrochloric acid, extend the work-ing life of the equipment such as plate-type heat exchanger, graphite heat exchanger, tail gas washing tower and improve plant efficiency.
Further, in described automatic feeder, store flocculation agent, and can quantitatively throw in by self-timing.Described flocculation agent is aluminium chlorohydroxide.Aluminium chlorohydroxide can well adsorption precipitation except the suspended impurity in anhydrating, improve the clarity of river.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
