Abstract
The invention discloses a boiler water primary treatment system. The system includes a raw water tank, a raw water pump, a quartz sand filter and an activated carbon filter, which are arranged along the flow direction and connected in order; and the system also comprises a dosing system between the raw water pump and the quartz sand filter, and the dosing system includes a PAC dosing system, a PAM dosing system, and a NACLO dosing system. According to the boiler water primary treatment system of the invention, the dosing systems arranged before the quartz sand filter add PAC (polyaluminium chloride), PAM (polypropylene amide) and NACLO (sodium hypochlorite) into the water, so that the colloidal particles turn into an unstable state and agglomerate into large particles and precipitate; therefore, the quartz sand filter can remove impurities of colloid and suspended solids in water thoroughly; and the addition of NACLO can prevent the propagation and proliferation of bacteria in raw water and the pipeline, and avoid damage to the subsequent water treatment equipment caused by bacteria.
Description
Technical field
The present invention relates to a kind of water treating equipment, particularly a kind of boiler feed water primary treatment system.
Background technology
Gas to generate electricity is the heat heating boiler utilizing gas-fired to produce, the steam driven electrical power generators that recycling boiler produces.
And boiler feed water needs through strict process, otherwise the easy fouling of boiler, reduce heat utilization ratio.In prior art, general employing quartz filter carries out preliminary treatment to boiler feed water, to remove the suspended substance, mud, colloid etc. in water, but because the colloidal solid in water is general all electronegative, both mutually exclusive between them, in water, constantly do pedesis again, very stable, not easily sink, this makes again quartz filter remove the impurity such as the colloidal solid in water thoroughly.
Summary of the invention
In view of this, the object of this invention is to provide a kind of boiler feed water primary treatment system, to solve the problem that quartz filter thoroughly can not remove water-borne glue body granule foreign.
Boiler feed water primary treatment system of the present invention, comprise the raw water box, raw water pump, quartz filter and the activated charcoal filter that connect successively along water (flow) direction, also comprise and be arranged on medicine system between raw water pump and quartz filter, described medicine system comprises that PAC adds medicine system, PAM adds medicine system and NACLO adds medicine system.
Further, described boiler feed water primary treatment system also comprises the heat exchanger be arranged between raw water pump and medicine system.
Further, described quartz filter and activated charcoal filter are two covers and are arranged in parallel.
Beneficial effect of the present invention:
Boiler feed water primary treatment system of the present invention, it by arranging medicine system before quartz filter, and Xiang Shuizhong adds PAC (aluminium chlorohydroxide), PAM (polypropylene acyl ammonia) and NACLO (clorox) respectively; After PAC adds can with small colloid, suspended substance in water even larger molecular organics mutually collide and bond, eliminate the Coulomb repulsion between colloidal solid, colloidal particle are made to become unsteady state, and make coalesces form larger particles, thus reach the object of precipitation, be equipped with PAM coagulant aids effect particularly remarkable; PAM is a kind of organic polymer coagulating agent, after water-soluble, can poly-condensation and hydrolysis be produced and form the high polymers of linear structure, this structure makes the two ends of line respectively adsorb colloidal solid, between apart from each other two particulates, play bonding bridging action, make particulate progressively become large, form oarse-grained flocs unit (alumen ustum), help the colloidal particle neutralized to condense further, thus make quartz filter can thoroughly remove the impurity such as water-borne glue body, suspended substance; And add the bacterial reproduction hyperplasia that NACLO can prevent in former water and pipeline, bacterium can be avoided to damage follow-up water treating equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of boiler feed water primary treatment system of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment boiler feed water primary treatment system, comprise the raw water box 1, raw water pump 2, quartz filter 3 and the activated charcoal filter 4 that connect successively along water (flow) direction, also comprise and be arranged on medicine system between raw water pump and quartz filter, described medicine system comprises that PAC adds medicine system 5, PAM adds medicine system 6 and NACLO adds medicine system 7.
The present embodiment boiler feed water primary treatment system, it by arranging medicine system before quartz filter, and Xiang Shuizhong adds PAC (aluminium chlorohydroxide), PAM (polypropylene acyl ammonia) and NACLO (clorox) respectively; After PAC adds can with small colloid, suspended substance in water even larger molecular organics mutually collide and bond, eliminate the Coulomb repulsion between colloidal solid, colloidal particle are made to become unsteady state, and make coalesces form larger particles, thus reach the object of precipitation, be equipped with PAM coagulant aids effect particularly remarkable; PAM is a kind of organic polymer coagulating agent, after water-soluble, can poly-condensation and hydrolysis be produced and form the high polymers of linear structure, this structure makes the two ends of line respectively adsorb colloidal solid, between apart from each other two particulates, play bonding bridging action, make particulate progressively become large, form oarse-grained flocs unit (alumen ustum), help the colloidal particle neutralized to condense further, thus make quartz filter can thoroughly remove the impurity such as water-borne glue body, suspended substance; And add the bacterial reproduction hyperplasia that NACLO can prevent in former water and pipeline, bacterium can be avoided to damage follow-up water treating equipment.
In the present embodiment boiler feed water primary treatment system, activated carbon filter can remove organism in water, germ and absorption chlorine residue.Because gac has great specific surface area, produce very strong adsorptive power, can bacterium in planar water, microorganism, organism and chlorine residue, reach the water inlet index request of reverse osmosis, can protect follow-up reverse osmosis water treating equipment.
As the improvement to the present embodiment, this boiler feed water primary treatment system also comprises the heat exchanger 8 be arranged between raw water pump and medicine system, and heat exchanger 8 can carry out preheating to source water, is conducive to dissolving and the reaction of accelerating medicament.
As the improvement to the present embodiment, described quartz filter and activated charcoal filter are two covers and are arranged in parallel, and can improve filtration treatment efficiency and better tackle equipment failure.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
