Abstract

The utility model discloses an ORP (Oxidation-Reduction Potential) adjustable char filter device which comprises a char filter body which is respectively provided with a water inlet pipe and a water outlet pipe. The improved char filter device further comprises an ORP detection sensor, an ORP meter and a chemical adding device, wherein the ORP detection sensor is fixedly arranged at the tail end of the water outlet pipe, the ORP meter is electrically communicated with the ORP detection sensor, the chemical adding device comprises a chemical adding barrel, an ORP chemical adding pump, a chemical pumping pipe and a medicine delivery pipe, and the ORP meter is electrically communicated with the chemical adding pump. The char filter device is automatically medicated by the chemical adding device, so that ORP value in the char filter device is in a substantially stable state, thereby, prolonging the regeneration period of the active carbon and reducing the regeneration time. Therefore, the labor intensity of the operator is reduced, and meanwhile, the chemicals and water are further saved, and the production cost is lowered.

Description

The charcoal filter device that a kind of ORP is adjustable

Technical field

The utility model belongs to ultrapure water processing unit field, particularly the adjustable improvement charcoal filter device of a kind of ORP.

Background technology

In the production technique of ultrapure water, need to use charcoal filter device water is carried out to corresponding follow-uply process again, complete by gac specifically, gac needs regeneration to reuse after using some cycles, cycle is generally 15 days, after the gac life-time service of regenerating, also can produce complete failure and scrap, be 3 years duration of service, why gac needs regeneration to be because the ORP value in anion bed changes, ORP refers to oxidation-reduction degree, ORP value variation meeting produces very large impact to Properties of Activated Carbon, so charcoal is filtered in use, staff need to regenerate to it frequently and scrap to change and process, this brings very large inconvenience with regard to the production operation of giving us, labor intensity of operating staff is very large, and a large amount of medicaments and water are wasted, if the ORP that can filter in device charcoal controls and makes it adjusting automatically in basicly stable, the problems referred to above can solve.

The technical problems to be solved in the utility model is to provide a kind of ORP value improvement anion bed adjustable, easy to use.

Utility model content

Use the problems such as inconvenient, operator's labour intensity is large for solving above-mentioned prior art operation, the utility model adopts following technical scheme:

The utility model provides the adjustable charcoal filter device of a kind of ORP, comprise charcoal filter body, on described charcoal filter body, be respectively arranged with water inlet pipe and rising pipe, improved charcoal filter device also comprises ORP detecting sensor, ORP table and chemicals dosing plant, described ORP detecting sensor is fixedly installed on described rising pipe end, described ORP table and described ORP detecting sensor electrical communication, described chemicals dosing plant comprises medicine-adding bin, ORP dosing pump, take out pencil and drug feeding pipe, described ORP table and described dosing pump electrical communication, described ORP table is controlled described dosing pump work, the described pencil one end of taking out is communicated with described medicine-adding bin, the other end is communicated with described ORP dosing pump, described drug feeding pipe one end is communicated with described dosing pump, the other end is communicated with described water inlet pipe.

The beneficial effects of the utility model are: filter device Automatic Dosing by chemicals dosing plant to charcoal, ensure in charcoal filter device that ORP value is in basicly stable state, can extend the regeneration period of gac, reduce regeneration times, thereby reduce operator's labour intensity, also saved medicament and water, reduced production cost simultaneously.

Brief description of the drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Embodiment

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Refer to Fig. 1, the charcoal filter device that a kind of ORP is adjustable, comprise charcoal filter body 1, on described charcoal filter body 1, be respectively arranged with water inlet pipe 11 and rising pipe 12, water is continual to be flow to from water inlet pipe 11, after charcoal filter body 1 is interior, flow out through rising pipe 12 again, improved charcoal filter device also comprises ORP detecting sensor 2, ORP table 3 and chemicals dosing plant 4, described ORP detecting sensor 2 is fixedly installed on described rising pipe 12 ends, described ORP table 3 and described ORP detecting sensor 2 electrical communication, by ORP detecting sensor 2, the ORP value in device is carried out to Real-Time Monitoring, the ORP information that ORP detecting sensor 2 detects can be transferred in ORP table 3 in time, ORP table 3 needs first to set an ORP reference value before use, ORP refers to oxidation-reduction degree, ORP value changes will directly affect the performance of gac, described chemicals dosing plant 4 comprises medicine-adding bin 41, ORP dosing pump 42, take out pencil 43 and drug feeding pipe 44, described ORP table 3 and described ORP dosing pump 42 electrical communication, described ORP table 3 is controlled described ORP dosing pump 42 and is worked, described pencil 43 one end of taking out are communicated with described medicine-adding bin 41, the other end is communicated with described ORP dosing pump 42, described drug feeding pipe 44 one end are communicated with described ORP dosing pump 42, the other end is communicated with described water inlet pipe 11, when the ORP value that ORP detecting sensor 2 detects is not presetting within the scope of ORP, ORP table 3 sends instruction will to dosing pump 42, ORP dosing pump 42 will be started working and be filtered the interior dosing of body 1 to charcoal timely, what in described medicine-adding bin 41, put is sodium bisulfite medicament, carry out the ORP value in balance charcoal filter device by sodium bisulfite, thereby ensure that the regeneration of activated carbon cycle in charcoal filter device is extended, and then minimizing regeneration times, reduction operator's that like this can be suitable labour intensity, also reduced the use of medicament and water simultaneously, and the ORP value of traditional charcoal filter is nonadjustable, the regeneration of activated carbon cycle in charcoal filter device is also very short, need to carry out regenerative operation to gac frequently, medicament and water resources were so both wasted, also improved operator's labour intensity, by above-mentioned improvement, can address the above problem.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
