Description
Technical field
It is specifically a kind of for building life the utility model is related to build domestic hot-water's water quality safeguards technique field
The disinfectant preparation facilities and dosing control system of hot water.
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 washes one's face and rinses one's mouth, does 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 wall of the pipe 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 to be unable to get effective guarantee if being not provided with disinfectant supplement and adding facility.
Currently, although the safety of domestic water causes extensive concern and payes attention to, but still there are many hot water water quality
Chemical safety and biosafety issues are to be resolved.The disinfecting process of domestic hot-water mostly uses domestic water system 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 is 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 production quantity 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 when hot water, leads to remaining disinfection in hot water occur
The phenomenon that agent completely consumes, microorganism largely grows causes great threat 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, improves 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 problemss.Chlorine, chloramines, ozone, titanium dioxide
The bacteria inactivation rate effect of chlorine very well and has continuous disinfection effect, but rate of decay in the hot water is all quickly, and increases
Disinfectant throwing amount can cause disinfection by-products production quantity to dramatically increase.Therefore conventional chlorine, chloramines, ozone, chlorine dioxide etc. is all
The disinfecting process of hot water can not be effectively applied to.
In order to make hot-water heating system keep biological safety for a long time, needs to add and do not disappeared by Water Temperature, attenuation amplitude are small
Toxic agent.Silver ion has good sterilizing effect, 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, and disinfection is not influenced by hot water temperature, can meet life heat well
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 the requirement of (0.05mg/L) limit value of silver ion content in, it is therefore desirable to stringent
Control the dosage of silver ion.Under the premise of ensureing domestic hot-water's biological safety, 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
It improves silver ion disinfection effect, reduce the exceeded risk of silver ion content, may be used composite disinfecting mode, sterilized meeting
Under the premise of effect, the dosage of silver ion disinfectant is greatly lowered.Hot water supply system carries out periodic cleaning and impact disappears
When malicious, the silver ion disinfectant for adding higher concentration in a short time is needed, it is thorough to the carry out such as hot-water pipeline system and facility
Cleaning and disinfection.
A kind of disinfectant preparation facilities and dosing control system for building domestic hot-water provided by the utility model, just
It is to be proposed under the conditions of the actual demand of above-mentioned hot water supply system, has both may be implemented to ensure domestic hot-water's biological safety item
Silver ion disinfectant under part prepares and quantifies online feeding function and silver ion and prepares and quantify online with other disinfectants
The compound dosing function of adding, and hot water supply system's periodic cleaning may be implemented and impact the silver ion disinfection under conditions for sterilization
Agent mother liquor prepares function online and high concentration silver ion disinfectant quantitatively adds control function.
