Abstract
The utility model discloses a vertical type amphoteric ion exchanger for the treatment of boiler water supply and water quality outside the boiler. The exchanger is divided into an upper and a lower two exchange chambers and a middle reaction chamber, one exchange chamber is a Na type (positive) ion exchange chamber, and the other exchange chamber is an H type (negative) ion exchange chamber. After tap water respectively enters into the two exchange chambers for exchange, the tap water can respectively enter into the reaction chamber for reaction, and qualified water quality needed by the boiler can be obtained. Meanwhile, the two exchange chambers are respectively provided with a reverse cleaning pipe, a counter-current regeneration pipe, etc., and when the water quality of water supply is unqualified, the reverse cleaning pipe and the counter-current regeneration pipe can respectively carry out cleaning and regeneration for each exchange chamber in order to ensure the water quality of the water supply. The exchanger with easy manufacture, less investment and simple and reliable operation can remove the hardness in the water, and can reduce or remove the alkalinity in the water.
Description
The utility model relates to the amphoteric ion exchanger of a kind of oiler feed, the outer water conditioning of pot.
Most Industrial Boiler and boiler for domestic to the processing of the outer water quality of pot, all adopt Na
+Exchange.Na
+Exchange can only be removed hardness in the water, can not remove basicity in the water.Its result makes pot alkalinity of water raise CO
2Condensing-type power plant enters in the steam, if can make condensate pipe that CO takes place
2Corrosion.Pot water is because of evaporation concentration, and basicity rises very fast.To this, people only control the basicity of pot water by method for discharging pollution (promptly discharge the higher pot water of a part of saltiness, strengthen moisturizing simultaneously, keep ordinary water-level).This method had both been wasted a large amount of fuel, had reduced exerting oneself of boiler again.However, still do not reach national standard, worsened steam quality, because of the basicity height, encouraged the foamy generation, make steam carry a pot water, i.e. alleged priming usually is directed at the Boiler Metallic corrosion.Its reaction formula is as follows:
2NaOH＋Fe (PH＞13)/() Na
2FeO
2＋H
2↑
Can find out that from following formula when the PH of pot water＞13, iron is dissolved, the most fearful is to produce caustic embrittlement (a kind of special corrosion form of Boiler Metallic).Causing this reason for corrosion, is the NaOH in pot water, makes to be subjected to corrosive metal generation embrittlement, and caustic embrittlement is serious, can cause boiler explosion.
For addressing this problem, people design mixed-bed exchanger, are about to two kinds of resins of different nature (Na, H or yin, yang resin), are blended in the interchanger, and it can guarantee the water quality that provides, but the resin regeneration difficulty that lost efficacy." H-Na ion-exchanger system ", " male-female ion-exchanger system " for another example, such " system " be though water treatment effect is good, invests too greatly, involves great expense, and the service requirements height is not easy to popularize and implements.
The purpose of this utility model is to design a kind of vertical amphoteric ion exchanger.This interchanger is made up of upper and lower two switch rooms and an intermediate reaction chamber, and it can remove hardness in the water, i.e. hardness ε ［ Ca
++]+[Mg
++; Can reduce or remove basicity in the water again, i.e. basicity ε ［ weak acid ］+［ OH
-.This interchanger is the water sampling assay at any time, can do corresponding the adjustment to feedwater again, need not to fall the alkali blowdown.
The purpose of this utility model is achieved in that this amphoteric ion exchanger is a vertical structure, interchanger is divided into switch room, following switch room, intermediate reaction chamber three parts, one of them is Na type (positive) ion-exchange chamber, and another then is H type (feminine gender) ion-exchange chamber.From the top of last switch room, the bottom of switch room down, introduce water pipe respectively to be communicated with water-supply pipe (running water pipe), water inlet control valve is housed therebetween separately.The top of the bottom of last switch room, following switch room draws water pipe to be communicated with reaction chamber, on rising pipe separately, outlet water control valve is housed, and two rising pipes link to each other with water shoot, communicate with upper and lower two switch rooms, and separately draining control valve are housed.The opposite of reaction chamber water inlet place sets out water pipe, and outlet water control valve is housed on it.The indoor resin of adorning of last exchange, intermediate drain installation is arranged in the middle and upper part, the intermediate drain installation skirt is communicated with water-supply pipe, water inlet control valve is housed therebetween, and this pipe is communicated with the rising pipe of upper and lower two switch rooms again simultaneously, and control valve is housed therebetween, this resin is installed between two filtering nets that are fixed on the indoor upper and lower part rising pipe of exchange, constitute fixed bed (also can make floating bed) if floating bed need not established intermediate drain installation.Between the resin of being adorned in the following switch room, device two filtering nets in being fixed in following switch room, under the rising pipe of top, constitute floating bed.The reverse drainage pipe is respectively drawn in the bottom of the top of last switch room, following switch room, on reverse drainage pipe separately, draining control valve is housed.On the rising pipe of upper and lower switch room, respectively draw reverse wash tube and be communicated with, and on reverse wash tube separately, control valve is housed with water-supply pipe.The bottom of last switch room connects the soft water water inlet pipe and advances the saline solution pipe, and control valve is housed respectively on two pipes.The top of following switch room connects the regenerated liquid liquid-inlet pipe, and control valve is housed on it.
This amphoteric ion exchanger has the following advantages: the water quality having guaranteed oiler feed with imitating, guarantee the safe operation of equipment, and prolonged the work-ing life of equipment.Realized energy-conservation, low consumption, efficient.This interchanger, easy to manufacture, less investment, simple to operate, reliable.
