Compared with the prior art, the beneficial effects of the utility model are that: the use amount of ion exchange resin, reverse osmosis material and scale inhibitor can be effectively reduced, and the production and operation cost is reduced; the external discharge amount of the external exchange water due to the increase of the hardness of the water is reduced.
Description
Technical field
The utility model relates to the softening field of recirculated water, relates in particular to a kind of device that reduces recirculated water hardness.
Background technology
In recirculating cooling water system, some salts that very easily form incrustation scale are as the inverse ratio that is varied to of solubleness in water of carbonate, vitriol, silicate and temperature, along with the rising of water temperature, the carbonate, vitriol, the silicate that were originally dissolved in water will separate out and be attached on tube wall.The generation of incrustation scale is mainly the precipitation of some water-fast materials, such as CaCO
3, Zn (OH)
2, Ca
3(PO
4)
2, CaS
io
3deng, because the thermal resistance of incrustation scale is 40 times of steel plate, will have a strong impact on flow velocity and heat exchange efficiency, waste energy.
The method that incrustation scale forms that prevents or alleviate often adopting at present has: a kind of is that ion exchange softening method, reverse osmosis are produced soft water, de-mineralized water; Another kind method is to use Scale inhibitors.No matter be soft water, DW system demineralized water system or the system of using Scale inhibitors, because the usage quantity of ion exchange resin, reverse osmosis material, Scale inhibitors is larger, working cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of device that reduces recirculated water hardness, utilizes fume afterheat to reduce recirculated water hardness, alleviates and prepares soft water, de-mineralized water and use the high problem of working cost in Scale inhibitors process.
For achieving the above object, the technical solution of the utility model is:
A kind of device that reduces recirculated water hardness, comprise interchanger one, interchanger two, waste heat fume pipe and water cooler, interchanger one and interchanger two are connected on circulating pipe and waste heat fume pipe, are respectively equipped with water inlet A, water outlet A on interchanger one ', enter mouth C, smoke outlet C ', clean-out system entrance E and clean-out system outlet E '; On interchanger two, be respectively equipped with water inlet B, water outlet B ', enter mouth D, smoke outlet D ', clean-out system entrance F and clean-out system outlet F '; The water inlet B of the water inlet A of interchanger one and interchanger two valve of respectively hanging oneself is connected with circulating pipe respectively, the water outlet A of interchanger one ' with the water outlet B of interchanger two ', and the valve of respectively hanging oneself is connected with water cooler respectively; The mouth D valve of respectively hanging oneself that enters that enters mouth C and interchanger two on interchanger one is connected with waste heat fume pipe respectively, and mouth C ' and the smoke outlet D ' of interchanger two valve of respectively hanging oneself that enters on interchanger one is connected with chimney respectively.
Compared with prior art, the beneficial effects of the utility model are: can effectively reduce the usage quantity of ion exchange resin, reverse osmosis material, Scale inhibitors, reduce the preparation expense of soft water, de-mineralized water; Reduce the usage quantity of Scale inhibitors, reduce production run expense; Improve the utilization ratio of the energy; The minimizing outer discharge capacity that outer row changes water because water hardness increases.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic block diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is a kind of device example structure schematic block diagram that reduces recirculated water hardness of the utility model, comprise interchanger one, interchanger two, waste heat fume pipe and water cooler, interchanger one and interchanger two are connected on circulating pipe and waste heat fume pipe, are respectively equipped with water inlet A, water outlet A on interchanger one ', enter mouth C, smoke outlet C ', clean-out system entrance E and clean-out system outlet E '; On interchanger two, be respectively equipped with water inlet B, water outlet B ', enter mouth D, smoke outlet D ', clean-out system entrance F and clean-out system outlet F '; The water inlet B of the water inlet A of interchanger one and interchanger two valve of respectively hanging oneself is connected with circulating pipe respectively, the water outlet A of interchanger one ' with the water outlet B of interchanger two ', and the valve of respectively hanging oneself is connected with water cooler respectively; The mouth D valve of respectively hanging oneself that enters that enters mouth C and interchanger two on interchanger one is connected with waste heat fume pipe respectively, and mouth C ' and the smoke outlet D ' of interchanger two valve of respectively hanging oneself that enters on interchanger one is connected with chimney respectively.
Interchanger one and interchanger two forms bypasses induction scaler systems, and two interchanger are worked by turns, one when heat exchange induction state, another is in cleaning and descaling state.The utility model utilizes the recirculated water in fume afterheat heating heat exchanger, the recirculated water that enters interchanger is rapidly heated, originally the carbonate, vitriol, the silicate that were dissolved in water will separate out precipitation, be attached on interchanger, and the water hardness of outflow heat exchanger can reduce greatly so; Higher through the water temp of interchanger, enter water cooler and return to the recycle system after cooling.The flow major part of water circulating pump output enters recirculated water user, and rest part enters bypass heating scaler system.
The utility model unit that resource can be used that is applicable to have surplus heat.Waste heat flue gas can be a kind of in all flue gases after converter, blast furnace, process furnace or fume afterheat generating.
