The method for preparing pure water commonly used at present has following several: (1) chemical laboratory utilizes steam condensate to prepare a small amount of pure water; (2) utilize a large amount of pure water of preparation such as reverse osmosis process; (3) utilize the resin ion exchange technique to prepare a large amount of pure water.But they all have significant disadvantages:
(1) to prepare the equipment yield of distilled water (being pure water) low for chemical laboratory, can not meet the needs of the industrial production of a large amount of pure water, and exist water temperature too high, the problem that required process is long, required equipment is complicated, cost is high of lowering the temperature.
(2) the just present domestic behaviour in service of reverse osmosis process sees that its utilising efficiency to water has only 30%～50%, wastes comparatively serious.And reverse osmosis membrane penetrates damage easily, the replacement cost costliness, and complex process requires the professional to manage use, apparatus expensive.
(3) the resin ion exchange technique prepares pure water system and need in time positive post and cloudy post adding acid, alkali are carried out manipulation of regeneration, otherwise the purity of water be difficult to guarantee after work for some time.
On the other hand, a large amount of steam is used in winter plant produced and heating.If the water of condensation that steam produces is not recovered utilization, cause water resource waste.In fact, water of condensation self has been satisfactory pure water just, and just prior art can't be apt to add utilization.In the prior art, to the two kinds of whereabouts that have of this heating water of condensation: reclaim and discharging.Power plant generally wishes factory's backwater, but this backwater need be laid water return pipeline between power plant and factory; And power plant utilizes mainly is heat contained in the backwater, and promptly return water temperature is high more good more.If the distance between factory and the power plant is too big, return water temperature is low, and the clean level of backwater can not get guaranteeing that the value of backwater has just reduced; But this moment water of condensation temperature for general applications or higher, if adopt alternate manner such as closed heat exchange fins to reclaim, the cost height is so often can see the phenomenon that water of condensation is drained.
Summary of the invention:
Purpose of the present invention is exactly in order to solve in the above-mentioned prior art, produce pure water cost height, and the water of condensation recovery back temperature that the steam of production and heating usefulness produces is not suitable for or water purity is not enough, and further tooling cost is too high, emitting can wasting problem.
For achieving the above object, the present invention proposes a kind of equipment for preparing pure water, comprise the water of condensation gathering device, it links to each other with the vapor condensation grid with heating with production, it is characterized in that: also comprise two or more cooling tank and at least one siphon pipes, have at least one to link to each other in the described cooling tank with described water of condensation gathering device; Link to each other by siphon pipe between at least two cooling tanks.
For achieving the above object, the present invention also proposes a kind of method for preparing pure water, comprise the steps: A, from produce and heating with gathering water of condensation the vapor condensation grid; (B) water of condensation that collects is incorporated into first step cooling tank; (C) water of the first step being lowered the temperature in the tank by siphon pipe is incorporated into next stage cooling tank; (D) repeating step (C), the water of previous stage being lowered the temperature in the tank by siphon pipe is incorporated into next stage cooling tank, and the water temperature in two-stage or multistage cooling tank in the last step cooling tank drops to predetermined temperature.
Owing to adopted above scheme, utilize siphon pipe and siphon principle, can under the situation of consumption of power not, the water of condensation of collecting be transported to next stage cooling tank, lower the temperature by common tank.Because of the equipment of employing is very simple, cost is extremely low.And when can make water temperature drop to suitable temperature, guaranteed the purity of water.The present invention can reclaim plant produced and the water of condensation that generates of the used steam of heating in winter, and a large amount of preparations are used for industrial pure water, can satisfy big industrial needs.Adopt system described in the invention, from whole society, not only make full use of water resources, save power, can also exempt the expense of laying water return pipeline.
Other purposes of the present invention and effect will describe by following embodiment.

Embodiment:
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
See Fig. 1, the equipment of this preparation pure water comprises water of condensation gathering device 11 and siphon pipe 20, water of condensation gathering device 11 links to each other with the vapor condensation grid with heating with production, the first step cooling tank 12 of cooling in the tank 12,13,14,15 link to each other with water of condensation gathering device 11 (be by valve among the figure, do not use siphon pipe) but also do not get rid of.Like this, just can from produce and heating with gathering water of condensation the vapor condensation grid, by siphon pipe the water of condensation that collects is incorporated into the cooling tank.
For further improving cooling-down effect, described cooling tank 12,13,14,15 has two or more (this example is four), link to each other by siphon pipe 20 successively between them, like this, the water of previous stage being lowered the temperature in the tank by siphon pipe is incorporated into next stage cooling tank, repeat this step, the water temperature in two-stage or multistage cooling tank in the last step cooling tank drops to predetermined temperature.As shown in Figure 1,12,13,14 is open tank, and 15 is closed tank, and the top has an observation, breather hole 151, and lid 152 is arranged on the breather hole.
In order to control current, on the described siphon pipe 20 valve 21 is arranged, be used to control that siphon pipe 20 is communicated with outside air or isolated.Effect by the valve control siphonage of control in the siphon pipe with stop.Such as, when the needs cleaning sink, can open valve 21, its inside is communicated with outside air, then siphonage disappears, and the current between tank and the tank interrupt, and can clean this moment to one of them tank.Clean the rear enclosed valve, then siphon pipe again can works better.
As shown in Figure 2, in order to make the water in the previous stage tank can flow into the next stage tank as much as possible, siphonal water inlet and water outlet are apart from the height of bottom of gullet about equally, but water outlet must than water inlet apart from bottom of gullet nearer (as Fig. 2: suggestion 100mm 〉=A 〉=0) so that the water in the previous stage tank can flow into the next stage tank as much as possible.Specific explanations is as follows: it is because our purpose is to import the water in the previous stage tank (that is: water inlet do tank) as much as possible next stage tank (that is: water outlet do tank) that (1) water inlet can not be lower than water outlet.If water outlet is higher than water inlet, then might the water surface in the previous stage tank do not reduce to as yet with the contour position of water inlet in, owing to water outlet has arrived the water surface of next stage tank, interrupted syphonic effect among being exposed to air, cause the water of previous stage tank can not fully flow into the next stage tank, the water surface of previous stage tank is limited by the abnormal phenomena of the water surface of next stage tank; (2) siphonal inwall has certain resistance, and there is difference of altitude in two mouths of pipe, can cause certain potential energy to overcome the resistance of tube wall.The standard of 0 ~ 100mm both can produce enough potential energy, limited this potential energy not too large (if potential energy is too big, then water flow impact pressure is big, and the settling of agitate water trench bottom makes water become muddy easily) again.In the present embodiment, the drop of water inlet and water outlet is 50mm.
Two mouths of pipe are near the bottom of tank, and (suggestion 400mm 〉=B 〉=200mm), concrete numerical value depends on the circumstances but still keep certain distance with bottom of gullet.So, in fact water inlet is 300 ~ 500mm apart from the distance of bottom of gullet, and choosing of such segment distance mainly is that the bottom of the tank of considering that water inlet is done has throw out.Water inlet keeps such segment distance apart from bottom of gullet, both can avoid throw out is sucked the next stage tank, is unlikely to again to cross far away and cause residual too much water in the tank apart from the bottom of tank.Provide such size range, crucial problem is to guarantee that (1) water inlet can not low excessively (then sucking throw out less than 300mm) easily apart from bottom of gullet, also can not be too high (then the residual water of water inlet one side is too many greater than 500mm); (2) drop of 0 (must be greater than 0, promptly the position of water outlet must be lower than water inlet) ~ 100mm (excessive then potential energy is big, stirs and make muddy the water of next stage easily) is arranged between water inlet and the water outlet.In the present embodiment, water outlet is 250mm apart from bottom of gullet.
Further strengthen cooling-down effect if desired, as shown in Figure 3, can make to include snakelike thermal diffusivity part in the described siphon pipe 20, for example the part that its middle part is exposed to air is arranged to snakelike radiating pipe, a similar heat radiation grid sheet.By making siphon-shaped is snakelike, makes the current cooling at siphon pipe.
Its principle of work and process are as follows:
1, steam condensate imports in the collection cooling tank 11;
2, the water in the collection cooling tank 11 enters cooling cooling tank 12 by valve;
3. siphonal caliber size is relevant with the water yield: the water yield greatly then caliber is big.In the time of first the use, water enters cooling tank 12 from collection cooling tank 11; After the water surface surpassed siphonal inlet, water entered in the siphon pipe, and kept identical liquid level with water in the cooling tank 12.The water surface continues to rise in the cooling tank 12, and when liquid level surpassed the height of siphon pipe horizontal component, water flowed into next stage tank, the tank 13 of promptly lowering the temperature under the effect of pressure.After the liquid level in the cooling tank 13 surpasses the siphon pipe water outlet, in whole siphon pipe, form the successive water column; After this as long as water outlet and water inlet are all imbedded below the water surface, whether the liquid level in the tank 12 of no matter lowering the temperature surpasses the height of siphon pipe horizontal component, and the liquid in the cooling tank 12 all can enter cooling tank 13 under the effect of siphon power.When causing two groove water temperature difference, realize that floating matter separates with sedimentary; And the like.The water surface in final all tanks is almost on same horizontal plane.
4, when water arrived sealing flume, temperature had been reduced to allowable temperature, and has kept clean level and specific conductivity.
5, through secondary filter 16, the finished product electrical conductivity of water is below 10, is equivalent to the specific conductivity (＜10 μ S/cm) of general tap water after the first-stage reverse osmosis system handles, can satisfy the requirement of general industry production to pure water.
6 if further improve specific conductivity, can make specific conductivity approach 0 at mixing column of the back of secondary filter 6 series connection.Mixing column plays the effect that improves purity.Secondary filter and mixing column can have been bought on the market.
The specific conductivity of the pure water after the processing is below 10, except that medical treatment and civilian drinking-water (problem of bacteria breed after mainly considering to stop using summer), can be widely used in industry and chemical industry, the required pure water in laboratory.
The present invention adopts siphon pipe, and each tank is connected combination, has utilized characteristics such as occurring in nature pressure difference, temperature head, difference of altitude dexterously, has realized following advantage:
Naturally cooling is without cooling apparatus.Can save the power consumption cost that equipment purchase cost and equipment use.Circuit design cleverly, realized: (1) utilizes siphon principle, makes the water in the previous stage tank also can enter the next stage tank under the situation that no machine drives, and saves the equipment purchase cost of buying water pump and the power consumption expense that pump operation causes.(2), so formed current, make of the heat dissipating layer motion of the high water of temperature, and the low depositing in water of temperature is in the bottom of tank to ingress of air in tank inside owing to the rising along with temperature of the proportion of water reduces.In the plural serial stage system, under the effect of siphonage, the water that enters the next stage tank from the previous stage tank all is the water that cooled off at the previous stage tank, descends step by step so can realize the water temp in each tank.Even it is very high that water of condensation is gone into the temperature at groove place, can realize that still the water temperature of terminal tank meets specific temperature requirements; Realize cooling fast.(3) owing to adopt the nature cooling, in order to strengthen the exchange capability of heat of the water surface, preceding what tank all is open.The rising pipe of previous stage tank is near the bottom of tank, and the water that not only guarantees to enter by siphon pipe the next stage tank is the lower water of temperature, and guarantees that the floating matter of previous stage flume surface can not enter the next stage tank.(4) water pipe of previous stage tank guarantees that the throw out of previous stage bottom of gullet can not be inhaled into the next stage tank near the bottom of tank but still apart from bottom of gullet certain distance is arranged.
