Description
Technical field
It is specifically a kind of to be used to build domestic hot-water the present invention relates to building domestic hot-water's water quality safeguards technique field
Disinfectant preparation facilities and dosing control system.
Background technology
Hot water supply system is the important component for building water system, and building domestic hot-water is mainly used in building
Bathing, wash one's face and rinse one's mouth, do washing, many aspects such as kitchen, has with human body and directly contacts, the water quality safety of domestic hot-water and water quality guarantee
It is the field paid special attention in recent years.The hydraulic detention time of hot water supply system is very long, and higher temperature also accelerates
Chlorine Decay speed, therefore generally existing chlorine residue is too low or even the problem of without chlorine residue, is conducive to bacterium, pathogenic microorganism is heating
Adhere on wall and inner-walls of duct and grow, condition is provided for biofilm formation so that domestic hot-water's water quality generally existing is pacified
Full hidden danger, keeps disinfectant residual, biological safety can not obtain effective guarantee if being not provided with disinfectant supplement and adding facility.
At present, although the security of domestic water causes extensive concern and payes attention to, but still has many hot water water quality
Chemical safety and biosafety issues are to be resolved.The disinfecting process of domestic hot-water uses domestic water system more at this stage
Disinfection technology and sterilization method, but since the operation characteristic of hot water water temperature and pipe-line system and domestic water have greatest differences,
There are great number of issues in practical applications.The temperature of domestic hot-water can locally be up to 70-90 generally at 35-60 DEG C, in heat exchanger
℃.Routine disinfection agent rate of decay dramatically increases, disinfection by-products growing amount showed increased；Hydraulic retention of the hot water in pipeline
Time is very long, and only user just has fresh water to add in hot-water heating system using during hot water, causes to occur remaining disinfection in hot water
The phenomenon that agent completely consumes, microorganism largely grows, great threat is caused to health.Therefore, it is badly in need of taking effectively disappearing
Malicious measure ensures the biological safety of hot water supply system.
The domestic hot-water's sterilization method that may be used mainly has supplement to add chlorine, chloramines, ozone, chlorine dioxide etc., to protect
Remaining disinfection agent content in domestic hot-water is held to meet《Standards for drinking water quality》(GB5749-2006) requirement；In addition also
Hot water supply system is periodically sterilized, frequently with thermal disinfection, improve the modes such as disinfectant throwing amount.Thermal disinfection is to micro-
The inactivating efficacy of biology is fine, but can only periodically use, and there are some potential safety problems.Chlorine, chloramines, ozone, titanium dioxide
The bacteria inactivation rate effect of chlorine is very well and with continuous disinfection effect, but rate of decay in the hot water is all quickly, and increases
Disinfectant throwing amount can cause disinfection by-products growing amount to dramatically increase.Therefore conventional chlorine, chloramines, ozone, chlorine dioxide etc. be all
The disinfecting process of hot water can not be effectively applied to.
Disappear to make hot-water heating system keep biological safety for a long time, it is necessary to add from Water Temperature, attenuation amplitude are small
Toxic agent.There is silver ion good sterilizing to act on, and can effectively inactivate the various microorganisms in hot water supply system, and silver
The rate of decay of ion in the hot water is very low, its disinfection can meet life heat well from the influence of hot water temperature
The disinfection of water and biological safety requirement.When adding silver ion in domestic hot-water and carrying out disinfection, water quality has to comply with China《It is raw
Sanitary standard for drinking water living》(GB5749-2006) to (0.05mg/L) limit value requirement of silver ion content in, it is therefore desirable to stringent
Control the dosage of silver ion.On the premise of domestic hot-water's biological safety is ensured, silver ion disinfection agent content is maintained
0.02-0.05mg/L, silver ion dosage need to carry out accuracy controlling, and it is exceeded to may result in silver ion content for slightly deviation.For
Improve silver ion disinfection effect, reduce the exceeded risk of silver ion content, can use composite disinfecting mode, meet disinfection
On the premise of effect, the dosage of silver ion disinfectant is greatly lowered.Hot water supply system carries out periodic cleaning and impact disappears
It is thorough to the carry out such as hot-water pipeline system and facility, it is necessary to add the silver ion disinfectant of higher concentration in a short time when malicious
Cleaning and disinfection.
A kind of disinfectant preparation facilities and dosing control system for being used to build domestic hot-water provided by the invention, exactly exists
Itd is proposed under the conditions of the actual demand of above-mentioned hot water supply system, can both realize ensure domestic hot-water's biological safety under the conditions of
Silver ion disinfectant prepare online and quantitatively feeding function and silver ion are prepared with quantitatively adding online with other disinfectants
Compound dosing function, and can realize that hot water supply system's periodic cleaning and the silver ion disinfectant impacted under conditions for sterilization are female
Liquid prepares function online and high concentration silver ion disinfectant quantitatively adds control function.

The control of holding or the impact disinfection of agent surplus；
When building hot water supply system's disinfection for composite, close in the first solenoid valve (3), second solenoid valve (5) and the 3rd electric
Magnet valve (7) is opened, silver ion generator (6) work, while in circulating pump (10) stopping, the 4th solenoid valve (8) and the 5th electromagnetism
Valve (11) is closed, and under conditions of the 6th solenoid valve (14) is opened, building domestic hot-water enters from domestic hot-water's water inlet tube interface (1)
Flowmeter (2), second solenoid valve (5), silver ion generator (6), the 3rd solenoid valve (7), injection valve (15) are flowed successively through, at the same time
Other disinfectant mother liquors in medicine storing pot (9) pass through metering pump (12), chemical feed pipe (13), the 6th solenoid valve (14), injection valve
(15) it is sequentially connected, the hot water for having added silver ion disinfectant is mixed with other disinfectants at injection valve (15) place, and formation disappears
The compound of toxic agent adds form, is then flowed out from domestic hot-water's water outlet interface tube (4).
7. according to the application process described in claim 6, it is characterised in that：Build hot water supply system and carry out silver ion disinfection
When, according to the numerical value of flowmeter (2), the ginseng such as content of organics, remaining disinfection agent content, micro organism quantity with reference to timing detection
After number participation statistical software is weighted optimization, comprehensive estimate and parameter tuning, silver ion disinfectant dosage is determined, by silver
Ion generator (6) prepares silver ion, is added to online in domestic hot-water online, and controls the concentration of silver ions in domestic hot-water
No more than 0.05mg/L, while disinfectant residual is ensured, avoid silver ion content in hot water exceeded.
8. according to the application process described in claim 6, it is characterised in that：When building hot water supply system's disinfection for composite,
According to flowmeter (2) numerical value, the parameter ginseng such as content of organics, remaining disinfection agent content, micro organism quantity with reference to timing detection
After being weighted optimization, comprehensive estimate and parameter tuning with statistical software, determine that silver ion disinfectant dosage disappears with other
Toxic agent dosage.
