Volume pump 1 and volume pump 1 electric power are 24W; Volume pump 1 and volume pump 1 peak flow are 38mL/min; Volume pump 1 and volume pump 1 operating frequency are 0 ~ 360spm; Chlorine dioxide yield 500 ~ 1000mL/h; Conversion rate of chlorine dioxide 80%; In-line pump 15 lift 45m; Temperature of reaction is about 70 DEG C.This generation systems selects hydrochloric acid and sodium chlorate to be raw material, wherein load sodium chlorate as raw material in head tank 1, hydrochloric acid is loaded as raw material in head tank 2 10, enter reactor 5 after pumping into mixing tank 11 in proportion respectively by volume pump to react, reacted chlorine dioxide liquid enters water supply line through induction units 7.The determination of titanium dioxide chlorine dose is controlled by chlorine residue measurement and control instrument 1, beyond producer 50m, water sampling is through chlorine residue sensing 2, sensor output 0 ~ 20mA analog quantity current signal enters chlorine residue measurement and control instrument 1 and compares process, then export variable pulse signal and control volume pump, volume pump controller changes the operating frequency of pump head at any time according to the change of pulse signal, namely change the flow of volume pump, make the chlorine residue of water supply line remain certain value.The amount of substance ratio participating in starting material hydrochloric acid and the sodium chlorate of reacting is 1: 1, and solid sodium chlorate dissolving ratio in water is generally defined as 1: 2, and namely sodium chlorate is 1.Hydrochloric acid and pumped into T-shaped mixing tank by two volume pumps in proportion by the sodium chlorate of dissolving, in T-shaped mixing tank, hydrochloric acid contacts with sodium chlorate.Mixed solution completely after contact enters reactor and stops reaction.In general, hydrochloric acid and sodium chlorate enter after reactor through mixing tank, and whether sufficient reacting is based on three conditions, i.e. temperature, time and pressure.Under the condition that temperature is certain, the mixed solution residence time is in the reactor directly proportional to chlorine dioxide yield, transformation efficiency.In the chemical reaction process of hydrochloric acid, sodium chlorate, obtain reaction effect more completely, except contact and residence time factor, in addition a very important factor is exactly temperature of reaction.At normal temperatures (10 ~ 25 DEG C), after two kinds of contact raw 40min, its transformation efficiency is 30%.65 ~ 72 DEG C time, after 40min, transformation efficiency is 65% ~ 80%.Prove through a large amount of experiments, when the temperature of reaction of hydrochloric acid and sodium chlorate must reach 70 DEG C, high yield and high-quality chlorine dioxide disinfection liquid could be obtained.For realizing higher temperature of reaction, reaction chamber adopts the manufacture of titanium material, has both improve the erosion resistance that heat transfer efficiency turn improves reactor.Arrange electric heater 6 below reactor, the heating tube of electric heater 6 is arranged in the reactor, for heating the temperature of heat-transfer medium water.WATER AS FLOW MEDIUM can reduce the thermograde of reactor, to ensure that dioxide peroxide steadily produces, throw in evenly, to improve sterilisation effect.The power of electric heater is controlled by temperature regulator 4, and temperature regulator 4 controls water liquid level simultaneously, to prevent overheated and dry combustion method.When the dioxide peroxide produced after reaction in reactor 5 is discharged, magnetic valve 8 is utilized to control output.
Also be stressed that the design of reaction pressure, illustrate that the pressure of reaction environment can not be too high through a large amount of tests, during pressure height, there is reversed reaction, the productive rate of dioxide peroxide declined in meeting inhibited reaction speed.Therefore hydrochloric acid and sodium chlorate reaction process must be made to be in normal pressure or negative pressure state, guarantee popular response.In order to make to be in atmospheric pressure state in reactor, the design of user's water supply line internal pressure and producer operation power water pressure is very important.Producer operation power water pressure must be greater than the internal pressure of user's water supply line could be soluble in water by thimerosal, and the water of assure feed water pipeline does not reflux.Therefore operation power Water oxidize chlorine disinfectant liquid enters user's water supply line.For this purpose, induction units 7 is set in exit.High pressure pipe pump is also received on water supply line, and the hydraulic pressure of water supply line, through in-line pump supercharging, makes induction units top hole pressure be greater than water pipe pressure, makes the input aperture pressure of induction units lower than 0 by variable diameter design.Only reactor just can be made to work under normal conditions lower than zero pressure, improve speed of response.In-line pump outlet is connected with the under meter 9 be arranged on equipment, and to observe the flow of power water, variable valve 14 is the measures in order to regulate producer induction units to produce zero pressure.In the disinfecting of Drinking Water, according to the relevant criterion of country, the chlorine content in process water is required at 0.2 ~ 0.7mg/L.Reach this standard, only way is the output flow controlling volume pump, and the amount of pumping into of volume pump is under the prerequisite that pump head stroke is certain, and the frequency controlling pump head is relatively accurate.Chlorine residue measurement and control instrument selects the product that market can directly be bought, the chlorine residue test specification 0 ~ 2mg/L of this instrument, output pulse signal variable range 0 ~ 360spm, and is provided with PID regulatory function.Can at the outer water sampling of water supply line 50m during use, chlorine residue signal controls the frequency of volume pump after chlorine residue controller calculates, with the productive rate of control generator.
As mentioned above, in high service pipeline, selecting chlorine dioxide generator to select, transformation efficiency is high, safe and reliable, installation and debugging convenient, the malleation chlorine dioxide generator of chlorine residue observation and control technology advanced person, requires that the output pressure of this producer dioxide peroxide mixed solution must be greater than water pipe pressure; The conversion rate of chlorine dioxide of producer must be greater than 65%; Being added to ducted chlorine dioxide concentration can not be too high, in order to avoid accelerate the corrosion speed of pipeline; Control chlorine content within the scope of regulation, improve the sterilisation quality of Drinking Water.This system increases the luminous efficiency of dioxide peroxide, reasonably can control chlorine dioxide concentration, ensure that water quality meets the requirements, ensure that people drink water health, solving in the generation systems of existing dioxide peroxide controls not tight for the concentration of dioxide peroxide, cause corrosive pipeline, easily produce harmful material, to problems such as the health of people cause damage.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; every according to technology of the present utility model, method in fact to any simple modification, equivalent variations that above embodiment is done, all fall within protection domain of the present utility model.
