Description
Technical field
The utility model relates to a kind of industrial cycle water treatment system, especially a kind ofly utilizes physics and chemical method to combine to handle the industrial circulating water zero discharge treatment system that industrial circulating water reaches the industrial cycle water zero discharge.
Background technology
As everyone knows; The concentration of lime carbonate just can not have been utilized after surpassing finite concentration again in the service water, the method for solution be exactly bleed off renew water or bleed off a part after again in the remaining service water interpolation pure water or softening water make the concentration of lime carbonate drop to proper level.After considering the Ordinary Wear and Tear of service water, additional pure water in the service water only looks like and has reached zero release, but this zero release is not zero release truly.Because 25% the condensed water of having an appointment in the pure water production process has been discharged; Most enterprises will produce about 25% the condensed water that emits in the pure water process be used as flushing cinder, towards ash or watering etc., this mode of utilizing condensed water is not industrial cycle water cooling system zero release truly equally.With regard to present scientific and technical present situation, have only and utilize the method for chemistry and physical treatment just can reach industrial cycle water zero discharge truly simultaneously.This method is exactly to utilize chemical method that super-saturated lime carbonate in the recirculated water is become grain slag with physical method grain slag to be filtered again, so that the lime carbonate concentration in the industrial circulating water reduces.The patent No. is that the Chinese invention patent of ZL200910073943.6 discloses a kind of multifunctional anti-incrustation corrosion inhibitor, generates grain slag after this chemical agent can react with the lime carbonate in the industrial circulating water.Therefore, establishing a kind of industrial circulating water zero discharge treatment system that utilizes this chemical agent to handle industrial circulating water, is the present technical issues that need to address.
Summary of the invention
The utility model technical problem to be solved provides a kind of industrial circulating water zero discharge treatment system.
The technical scheme that the utility model solves its technical problem is:
Industrial circulating water zero discharge treatment system; Circulating water pool is communicated with the import of interchanger through pumping conduit and recycle pump; The outlet of interchanger is communicated with the import of strainer through pump of constant delivery type, and the outlet of strainer is communicated with the import of cooling tower through water return pipeline, and cooling tower is located at the top of circulating water pool; On the pipeline between interchanger and the pump of constant delivery type, be provided with common pipe; The other end of common pipe is communicated with water return pipeline, is provided with on the pumping conduit between recycle pump and circulating water pool in recirculated water to add the chemical treatment water medicine chemical feed pipe that makes super-saturated lime carbonate in the recirculated water become grain slag, and chemical feed pipe is communicated with doser.
Compared with prior art, the utility model utilizes the existing bonded method of chemistry and physics, can realize industrial cycle water zero discharge truly.Industrial cycle water zero discharge does not truly also have successful examples at present at home and abroad.
The utility model is technical scheme preferably; Also comprise settling tank, be provided with the back flushing water inlet pipe that is communicated with strainer in the bottom of strainer, the other end of back flushing water inlet pipe is communicated with service water pipeline or circulating water pool; On the back flushing water inlet pipe, be provided with backwashing pump; Be provided with the back flushing rising pipe that is communicated with strainer at the top of strainer, the back flushing rising pipe leads to settling tank, on the back flushing rising pipe, is provided with pipe valve.Between settling tank and circulating water pool, be provided with deposition filtering water reuse pipe, on deposition filtering water reuse pipe, be provided with deposition filtering water reuse pump.
Add the strainer back flushing, strainer is increased the service life, grain slag content is higher in the water of filter back flushing, through settling tank deposition with top clear water reuse science more.
