Abstract
The invention discloses a boiler water treatment method which comprises the following steps: 1) pre-treating raw water by adopting a powerfully-magnetic water processor; 2) conveying the pretreated raw water to a pipeline mixer added with a mixed reagent, mixing the raw water and the mixed reagent, then conveying the water to a security filter, and performing filtration, wherein the mixed reagent comprises a bactericide, a coagulant, a scale inhibitor, a reducing agent, a cleaning agent and an absorbing agent; 3) conveying the filtered water to a reverse osmosis device through a high-pressure pump to perform reverse osmosis treatment; 4) conveying the water after reverse osmosis treatment to a degassing device to perform degassing treatment; 5) conveying the water after degassing treatment to an EDI device to perform desalting treatment; 6) performing pH adjustment on the water after desalting treatment; 7) inputting the water after pH adjustment to a boiler.
Description
Technical field
The invention belongs to boiler technology field, particularly to a kind of boiler water processing method.
Background technology
Boiler is the generation equipment of steam or hot water, is core technology using water as heat transfer medium, the quality therefore fed water, uses qualified water quality, is to ensure boiler safety stable operation and the qualified steam of output or the premise of hot water.If the produced harm of the poor water quality of feedwater has following several respects: 1, form fouling: incrustation scale causes the damage of boiler heating surface metal, reduce boiler service life；Reduce flow area in heat pipe, increase the flow resistance of pipe interior water circulation；Reduce the thermal efficiency, increase coal consumption amount or reduce boiler output；2, Boiler Metallic is caused to be corroded: the excess vol of abluent uses, and makes free sodium hydroxide too high or pH is low, can cause metal erosion in the case of containing again more neutral salt；3, steam quality deteriorates: pot water salinity height can occur priming phenomenon, pollutes steam.In the boiler that pressure is higher, silicon etc. can be optionally dissolved in steam.
Summary of the invention
It is an object of the invention to provide a kind of boiler water processing method.
For solving above technical problem, the present invention provides following technical scheme: a kind of boiler water processing method, comprises the steps:
1) use strong Management of magnetic water device that unboiled water is carried out pretreatment；
2) pretreated unboiled water being delivered to add the pipe-line mixer of confection, makes unboiled water mix with confection, then water is delivered to cartridge filter and filters, wherein, described confection includes antibacterial, mixes
Solidifying agent, antisludging agent, reducing agent, abluent and adsorbent；
3) water after filtering is delivered to reverse osmosis unit by high-pressure pump and carries out reverse-osmosis treated；
4) water through reverse-osmosis treated is delivered to degasser and be de-gassed process；
5) water processed through degassing is delivered to EDI device and carries out desalination process；
6) water processed through desalination is carried out pH regulation；
7) the water input boiler that will regulate through pH.
Preferably, the step 6) water to processing through desalination carries out pH regulation, and the pH value controlling water is 7.5.
Advantages of the present invention and having the beneficial effects that: provide a kind of boiler water processing method, it is high to removal of impurity, and it is high to produce water water quality, ensures boiler safety stable operation, improves the thermal efficiency.
Detailed description of the invention
The present invention will be further described in conjunction with the embodiments.
