Description
Technical field
The manufacture method of manufacturing installation and sterilization water of water the present invention relates to sterilize, more detailed saying, relate to and contain hypochlorous sterile water producing apparatus and manufacture method thereof, relate in former water such as tap water and well water, mix acidic aqueous solutions such as interpolation aqueous sodium hypochlorite solution and hydrochloric acid, sulphuric acid, acetic acid, make the device and method of hypochlorous acid sterilization water.
Background technology
Known in former water, adding mixing sodium hypochlorite (NaClO) and hydrochloric acid (HCl) etc., generate and produce very strong hypochlorous acid (HclO) the sterilization water of sterilizing power in the water.Yet, might produce deleterious chlorine (Cl during direct reaction such as sodium hypochlorite and hydrochloric acid
2).As the spy open flat 11-188083 communique and utility model login put down in writing in No. 3058642 communique, be thought of as the pH value that keeps suitable, the addition of sodium hypochlorite and hydrochloric acid etc. is adjusted on the limit, blended method and apparatus is added on the limit.
According to Figure 14 existing apparatus is made general description herein.Wherein use aqueous hydrochloric acid solution as acidic aqueous solution.In device as shown in Figure 14, at first, in former water supplying pipe road 120, connect non-return valve 121, after its downstream is divided into 2 bye-passes 123,124, in this bye-pass 123,124, connect non-return valve 125,126 respectively.And is connected with pipeline 127,128 that the interpolation nozzle 132 with aqueous sodium hypochlorite solution and aqueous hydrochloric acid solution add nozzle 137, by these interpolation nozzles 132,137, respectively aqueous sodium hypochlorite solution and aqueous hydrochloric acid solution are added in pipeline 127 and 128 in right amount.Have dilution agitator tank 129 and 130 at its downstream part, aqueous sodium hypochlorite solution and the aqueous hydrochloric acid solution that adds fully mixed with the former water of supply.Thereafter, pipeline 145,146 is collaborated, import by interflow pipeline 147 and mix in the agitator tank 148, each aqueous solution that dilutes is fully mixed.At this moment, for mixed liquor is fully mixed stirring, the way of taking is as required, strengthen to mix self volume of agitator tank 148, and connects dashpot in the downstream of mixing agitator tank 148.
In sterile water producing apparatus shown in Figure 14, generally be that bottom from vertical direction infeeds former water, by closing and mixing stop valve (not shown) that agitator tank 148 downstreams are connected when stopping to infeed former water, signal according to the pick off (not shown) that detects raw water flow etc., stop pump 134,139, also stop to add hypochlorous acid acid sodium aqueous solution and aqueous hydrochloric acid solution.Yet, add because detection stops to infeed later the stopping of former water, so the time that stops to add often lags behind the time that stops to infeed former water.Therefore, formation is added above-mentioned each aqueous solution to the former water that does not have flowing water.Thereby, near the interpolation nozzle 132,137 that adds aqueous sodium hypochlorite solution or aqueous hydrochloric acid solution, be detained the very high aqueous solution of sodium hypochlorite and concentration of hydrochloric acid.The proportion of retention aqueous sodium hypochlorite solution and aqueous hydrochloric acid solution overweights the proportion of former water like this, along with the time can be caused the precipitation diffusion, infeed near the mouth and move to former water, thereby the danger that exists sodium hypochlorite and hydrochloric acid reaction to produce chlorine, thus need each add nozzle 132,137 under closing means such as non-return valve 125,126 is set.

Describe diluted mixture unit 50 with bottom in detail with reference to Fig. 4 and Fig. 5.Fig. 4 is the unitary vertical section of diluted mixture shown in a Fig. 2 sketch map, and unshowned interpolation nozzle 21,26 is also shown in this Fig. 4 among Fig. 2.Keeping from clamping attitude up and down, these bodys 31,32,33 are centered on by outside cylindrical shell 50 body 31,32,33 by downside plate body 52 and accessory plate 53, the cylindrical shell 50 in the outside also by lower plate 52 and accessory plate 53 from clamping up and down.In order to prevent liquid, suitable encapsulant can be installed to external leakage.
The encapsulant that anti-liquid leaks also is set between upside plate body 51 and accessory plate 53.And then aqueous sodium hypochlorite solution adds nozzle 21 and aqueous hydrochloric acid solution interpolation nozzle 26 is inserted port 61,62 by the interpolation nozzle insertion mouth 57,58 of upside plate body 51 and the interpolation nozzle of accessory plate 53, in the insertion body 31,32.Add the encapsulant that also is provided with anti-liquid leakage usefulness on the nozzle 21,26 at each.Making the top of the body 33 that is connected of discharge line 44 of sterilization water with discharge, be provided with and make sterilization water flow into the interior outlet pass 79 of this body 33, and, be provided with the encapsulant that anti-leak is used in the lower end of this body 33., also the ditch that water flowing is used can be set below accessory plate 53 here, with the outlet pass 79 that replaces on body 33, being provided with.
Below interpolation nozzle shown in Figure 4 21,26 is described.The inside of adding nozzle 21 has path, and it distolaterally has a jet of opening to the side 77 simultaneously.Top ends in internal path is configured to taper valve body 75, is pressed on the valve seat by spring 76.Therefore, the power that overcomes spring 76 can not take place in the inside of this nozzle 21, and formation can not be by the structure of internal path from jet 77 ejections.
As shown in Figure 1, the aqueous sodium hypochlorite solution of being derived from groove 22 by pump 23 passes through pipeline 38,39, imports in the path that adds in the nozzle 21.At this moment, when automatic valve 24 shown in Figure 1 is closed, because the pressure in this nozzle 21 rises, the valve body 75 of interpolation nozzle 21 overcomes the pressure that falls spring 76 and opens, aqueous sodium hypochlorite solution adds in the former water of supply by tributary circuit 60, mix with former water on the limit, flows downwards in body 31 in the limit.
Stop for a long time making during the sterilization water, this adds nozzle 21 inner gasification gas that produce drains upward along pipeline 40, can retention in these nozzle 21 inside of formation aqueous sodium hypochlorite solution feeding pipe.Even the remained gas activating QI is arranged in the pipeline 40, open shut off valve 24, when primer pump 23 carries out the actuation cycle operation, also can become the circular flow of return slot 22 by pipeline 40, thus, gasification gas also can flow in the groove 22, owing to finally send in the groove 22, so can the addition of aqueous sodium hypochlorite solution not impacted.And the interpolation nozzle 26 that the opposing party's aqueous hydrochloric acid solution is used also forms same structure.
Following according to Fig. 6 to containing from groove 22,27 to the feeding pipe that adds nozzle 21,26 and describing to the pipe-line system of the return pipeline of groove 22,27 from adding nozzle 21,26.Be that example describes with interpolation nozzle 21 sides herein.Have a pair of coupling part in groove 22 bottoms of storing aqueous sodium hypochlorite solution, be connected with return pipeline 40 with feeding pipe 38, feeding pipe 38 is connected with pump 23, from groove 22 pump up water solution, imports 39 by pipeline 38 by primer pump 23.Pipeline 39 is connected with interpolation nozzle 21, and the aqueous solution that is aspirated by pump 23 infeeds in the interpolation nozzle 21.
At this moment, above the vertical direction in downstream, the connecting portion of configured slot 22 bottoms, pump 23, interpolation nozzle 21 dispose pipeline 38 and 39 from bottom to top successively, can not form protrusion angle upwards midway at this.Thus, be difficult to be detained by pipeline 38 and 39 with the condensed gas of the tiny gasification gas of pump 23 generations.Even produce little cohesion bubble, this bubble also can move to the supply of adding nozzle 21 along with the aqueous solution of pump 23, sends into and adds in the nozzle 21, sends at last to be located in 40 1 sides of pipeline vertically upward of adding in the nozzle 21.In former water, add the amount of aqueous solution like this, equal by the conveying capacity of pump 23, also just make the concentration of residual chlorine and the pH value that make sterilization water form stable.
Yet, change groove 22 backs or long-time in when out of service, enter the gas or the remained gas activating QI of pipeline 39, not only be present in the pipeline 40, also might arrive in the internal path of interpolation nozzle 21.Therefore, after changing groove 22 or after long-time out of service, open shut off valve 24 automatically, primer pump 23.Make aqueous solution from groove 22 like this,, turn back to again in the groove 22 by pipeline 38, pump 23, pipeline 39, interpolation nozzle 21, pipeline 40, shut off valve 24.Therefore,,, lead to gas in the pipeline that adds nozzle 21 and always push mobilely, to pipeline 40 or groove 22 in, move by pump 23 from groove 22.By this action, gasification gas can not be trapped in the feeding pipe of aqueous solution, can the addition of aqueous solution not exerted an influence yet.
Below with groove 22 1 sides as an example, according to Fig. 7 and Fig. 8 the coupling part of groove 22,27 and feeding pipe 38,41 is elaborated.The connecting portion 82 of tubular is installed in the bottom of groove 22, and at these connecting portion 82 inner valve bodies 83 that this connecting portion 82 is opened and closed of installing, it is pressed on the valve seat 85 by spring 84.Above-mentioned spring 84, to be clamped in plate and the compression of being supported by buckle for fastening of the state between the valve body 83, valve body 83 has the encapsulant that anti-liquid leaks usefulness.Relative with it, the connector 87 that is connected with pipeline 38 top ends has protuberance 88, also is provided with anti-liquid and leaks the encapsulant of usefulness in this protuberance 88, forms path 89 simultaneously in inside.
Then being connected of connecting portion 82 and connector 87, because groove 22 is installed on this device, the connecting portion 82 by groove 22 bottoms and the protuberance 87 of connector 87 compress and carry out.By making valve body 83 relative the pressing of protuberance 88 and connecting portion 82, as shown in Figure 8, the elastic force that the valve body 83 of connecting portion 82 has overcome spring 84 is moved upward, and 85 forms gaps owing to lift off a seat, so groove 22 and pipeline 38 form connection status.
