Description

The decontamination system of online production sodium hypochlorite
Technical field
This utility model belongs to water-treatment technology field, is specifically related to the decontamination system of a kind of online production sodium hypochlorite.
Background technology
Along with country is more and more higher to safety in production degree of attention, the transport of hazardous chemical and the supervision of use are more come The strictest, lattice, along with the quickening of urban development speed, waterworks is increasingly closer to resident living area.Requirement by chlorine safety Growing with each passing day, serious threat the normal safe of main waterworks, city and is produced.
It is currently used for the Main Means of water body disinfection to add chlorine, chlorine dioxide, sodium hypochlorite, ozone and ultraviolet and disappear Poison.Add liquid chlorine and be still the most frequently used sterilization method, but the safety added due to liquid chlorine is the most progressively by city tap-water factory Authorities are paid attention to, and liquor natrii hypochloritis is the broad-spectrum sterilization algicide that a kind of purposes is extremely wide.It not only has the strongest Sterilization algae removal effect, and the sodium hypochlorite prepared of on-the-spot electrolytic brine is due to its concentration dangerous materials concentration limit less than 1% System, stability is the best, it is simple to the safety of the excellence such as storage and cheap use cost, by waterworks, existing down town Prioritizing selection technique as liquid chlorine substitute technology.
The approach obtaining liquor natrii hypochloritis at present mainly has chlor-alkali plant manufacture and is prepared in situ two kinds, and chlor-alkali plant is produced Commodity sodium hypochlorite available chlorine content be 10%~13%, but experimental results demonstrate, the liquor natrii hypochloritis of high concentration holds very much Easily decomposing, when temperature is less than 25 DEG C, every day loses effective chlorine 0.1-0.15 mg/L, and during more than 30 DEG C, every day loses and reaches 0.3- 0.7mg/L, makes to be finished within several weeks after usually requiring that purchase.So, its preservation condition is the harshest, increase transport and management Difficulty and cost.Owing to commodity liquor natrii hypochloritis is the side-product of chlor-alkali plant, purity is the highest, alkalinity and objectionable impurities amount Height, applies in general to commercial Application, it is impossible to for drinking water.Sodium hypochlorite pH value is up to more than 11.0, is very easy to fouling, because of This also needs to regulate pH value process procedure further.The commodity sodium hypochlorite of high concentration is the same with chlorine broadly falls into dangerous materials, liquid Chlorine is 2 class dangerous materials, and commodity sodium hypochlorite is 8 class dangerous materials.There is stronger corrosivity, during transport, there is potential safety hazard.
Utility model content
In view of this, the purpose of this utility model is to provide the decontamination system of a kind of online production sodium hypochlorite.
The purpose of this utility model is realized by such technical scheme, the sterilization system of online production sodium hypochlorite System is including water softener, dissolved salt tank, hypochlorite generator, sodium hypochlorite storage tank, PLC control cabinet and chlorination skid, described soft Hydrophone, dissolved salt tank, hypochlorite generator, sodium hypochlorite storage tank and chlorination skid are sequentially connected with, and described PLC control cabinet is with secondary Sodium chlorate generator connects.
Further, also including cleaning device, described cleaning device is connected with hypochlorite generator.
Further, also including diluting skid, described dilution skid is connected between sodium hypochlorite storage tank and chlorination skid.
Further, also including softening water storage tank, described softening water storage tank is connected to water softener outlet and hypochlorous acid Between sodium generator.
Further, it is connected to soften and is provided with effusion meter and valve on the pipeline between water storage tank and hypochlorite generator Door, described effusion meter, valve electrically connect with PLC control cabinet respectively;The pipeline being connected between hypochlorite generator and water softener On be provided with valve.
Further, described sodium hypochlorite storage tank is provided with liquid level sensor, described liquid level sensor and PLC control cabinet Connect.
Further, the axial flow blower being arranged on sodium hypochlorite storage tank, described axial flow blower and PLC control cabinet are also included Connect.
Owing to have employed technique scheme, this utility model has the advantage that
1, product simple, cost-effective, reduces total disinfection cost;2, on-demand production reduces operation cost; 3, constant disinfection concentration improves water quality;4, less disinfection byproduct (DBP);5, the chemicals (raw material or product) of benign; 6, the potential safety hazard of chemicals mass storage is avoided;7, storage and the process of danger is substantially reduced, the risk of water factory employee Also reduce;8, there is no potential leakage chlorine risk, reduce the threat to public safety;9, the relevant duty in transportation is avoided Appoint;10, the cost of pH regulator is decreased.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this practicality Novel it is described in further detail, wherein:
Fig. 1 is the theory diagram that this reality is novel.
Specific embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail;Should be appreciated that preferred reality Execute example only for explanation this utility model rather than in order to limit protection domain of the present utility model.
The decontamination system of online production sodium hypochlorite, including water softener, dissolved salt tank, hypochlorite generator, sodium hypochlorite Storage tank, PLC control cabinet and chlorination skid, described water softener, dissolved salt tank, hypochlorite generator, sodium hypochlorite storage tank and Chlorination skid is sequentially connected with, and described PLC control cabinet is connected with hypochlorite generator.
Tap water water inlet is after water softener softens, and calcium, magnesium ion in water are removed, and generates and softens water.A part softens Water enters softening water tank storage, provides dilution water for hypochlorite generator;Another part enters dissolved salt tank and dissolves Sal, becomes Saturated aqueous common salt.Saturated aqueous common salt mixes through the accurate water distribution of dosing pump and dilution water, enters hypochlorite generator.
