Chlorine disinfectant constant temperature maintenance system {Chlorine disinfectant constant temparature maintenance system}

The present invention relates to a chlorine-based disinfectant constant temperature maintenance system, and more particularly, to a chlorine-based disinfectant constant temperature maintenance system for maintaining the temperature of a tank storing the chlorine-based disinfectant at a constant temperature to maintain the physical properties and quality of the chlorine-based disinfectant.

The disinfection method applied to the conventional disinfection process of water and sewage is chlorine disinfection, and after vaporizing liquid chlorine with a vaporizer, it is supplied to raw water to be treated through an ejector and disinfected. However, this disinfection method has a problem of high risk in terms of safety management because it contains the danger of toxic substances and the danger of high-pressure gas at the same time by forming chlorine, which is a toxic substance, into a high-pressure gas.

In order to solve this problem, in recent years, the disinfection method is being replaced by chlorine-based disinfectants, which are liquid substances containing chlorine. was replaced by the disinfection method by In Korea, pilot installation and operation started in 2010, and it was introduced in earnest in Seoul in 2013, and in 2019, it is also being introduced to local, county, and small governments.

As the chlorine-based disinfectant, one kind of sodium hypochlorite is used in the disinfection process of water and sewage, and sodium hypochlorite is manufactured to have an effective chlorine concentration of 0.8% to 12%. For storage of sodium hypochlorite, a storage tank made of polyethylene or rigid polyvinyl chloride is generally used to prevent corrosion.

On the other hand, according to the data on changes in the effective chlorine and harmful substances content according to the disinfectant storage institution of the Ministry of Food Safety of the Republic of Korea, the chlorate, a hazardous substance, increases 133-286 times of the initial concentration in the 12th week under the storage condition of sodium hypochlorite at 30℃. , a 4-fold increase at 20°C and almost no change in concentration at 4°C even for 12 weeks, proving that low-temperature storage of sodium hypochlorite is the optimal storage method.

In this regard, as disclosed in Korean Patent No. 10-1393361 'A device for manufacturing sodium hypochlorite', the temperature of the solution rises by 40 to 50 ° C during electrolysis of brine to produce hypochlorite, so a cooler is mainly used in the production facility process. Although comparatively many studies have been made on its use, research is insignificant on the technology of keeping the prepared sodium hypochlorite chemical solution at a low temperature when stored in a storage container.

In particular, in the case of using a cooler in the process of production equipment as in Korea Patent Registration No. 10-1393361, since it is cooled using water used in the process of production equipment, it is possible to lower the heat shielding temperature of 40-50℃ to about 20-30℃. Although it is possible, it is difficult to lower it below that, and since the chemically unstable room temperature is maintained in sodium hypochlorite, the effective chlorine concentration decreases over time.

The thermal conductivity of the artificial graphite sheet 210 is about 2,000 W/mK, which is four times higher than the thermal conductivity of copper.

When the heat transfer tube 200 coated with the graphite sheet 210 is located inside the storage unit 100 , the graphite sheet 210 is exposed to a chlorine-based disinfectant. Graphite is known to have a significant corrosion resistance with respect to sodium hypochlorite at a concentration of 5% at room temperature, at a concentration of 5% at room temperature, the corrosion resistance decreases sharply, but does not corrode well below 40 degrees. In the case of the chlorine-based disinfectant constant temperature system of the present invention, it is maintained at 4°C to 14°C, and the concentration of sodium hypochlorite is maintained at 5% to 15%.
