Description

Technical Field

[0001] The utility model relates to the field of water treatment engineering construction, in particular to an integrated skid-mounted device for cleaning and removing bleaching powder disinfection reaction residues. Background Art

[0002] At present, large domestic water plants mainly use liquid chlorine and commercial sodium hypochlorite to sterilize tap water. Small and medium-sized water plants and township water plants use different methods to disinfect tap water, including liquid chlorine, bleaching powder, sodium hypochlorite generators, etc. According to the survey, due to the insufficient deployment rate of disinfection facilities and disinfection agents and the failure of the operation of existing disinfection facilities to fully consider the quality level of operators and the convenience of facility application, the actual application effect of most projects is poor. Among various common disinfection methods, chlorine disinfection is still the most mature technology, the easiest to detect, the lowest operating cost and the best continuous disinfection effect. Among the various application forms of chlorine disinfection, the risk pressure of liquid chlorine in the transportation, storage and use process is increasing. The transformation of sodium hypochlorite to replace liquid chlorine for tap water disinfection in cities such as Beijing and Shanghai has basically completed the transformation work of sodium hypochlorite replacing liquid chlorine, but sodium hypochlorite transportation requires special tank trucks and storage requires special storage tanks, which is troublesome in transportation and storage, and the storage and transportation costs are high. Especially for some water plants with smaller and more dispersed water production scales, the storage and transportation costs of obtaining commercial sodium hypochlorite are even higher than the value of the product itself.

[0003] The sodium-based bleaching powder does not have the complicated preparation process of sodium hypochlorite generators and chlorine dioxide generators for disinfection. There is no process of transferring the manufacturing cost of the agent to consumers and the process of consumers passively learning the process principles. When disinfecting and sterilizing, it only needs to wait for the bleaching powder particles to be physically dissolved in water before it can be put into use. The disinfection facilities are simple and the investment is low. Therefore, the bleaching powder, which is not restricted by regions, is not affected by the scale of water production, and is not restricted by traffic conditions, is safe and convenient to transport, store, and put into use, greatly caters to the current situation of rural drinking water project disinfection, and is also being recognized and affirmed by users.

[0004] Bleaching powder, commonly known as "dry chlorine", uses solid calcium hypochlorite to convert liquid chlorine, which is inconvenient to store, transport and use, into a conventional broad-spectrum disinfectant, sterilant, bleach and oxidant that is easy to store and use. The main component of bleaching powder is calcium hypochlorite, and it contains a small amount of calcium carbonate, sodium chloride and water. Its effective chlorine content reaches more than 70%. It has a pungent smell and has the advantages of high efficiency, stability, convenience, and suitability for long-term storage and transportation. The disinfection and sterilization principle of bleaching powder is that it forms hypochlorous acid through its hydrolysis, and hypochlorous acid further decomposes to form new ecological oxygen [O]. The extremely strong oxidizing property of new ecological oxygen denatures proteins and other substances on bacteria and viruses, thereby killing pathogenic microorganisms. In the process of sterilization and virus killing, hypochlorous acid can not only act on cell walls and virus shells, but also penetrate into bacteria (viruses) because of its small molecules and no charge, and undergo oxidation reactions with organic polymers such as bacterial (viral) proteins, nucleic acids and enzymes, thereby killing pathogenic microorganisms. The chloride ions produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and viruses, causing the cells to lose their activity and die.

[0005] The process can be simply expressed by the chemical equation as follows:

[0006] Ca(ClO)2+2H2O→2HClO+Ca(OH)2

[0007] Ca(ClO)2+H2O+CO2→2HClO+CaCO3

[0008] HClO→HCl+[O]

[0009] The use of bleaching powder in water disinfection is a simple dissolution reaction process. At the concentration used, calcium hypochlorite reacts completely with the water to be disinfected and sterilized, is relatively stable, and has no obvious chlorine smell. From daily use experience and the above reaction formula, it can be seen that after the bleaching powder reacts with water, there is a 20% residue precipitation (including calcium hydroxide and calcium carbonate). The residue attached to these precipitations will gather at the bottom of the mixing tank, bleaching powder solution tank, clarified liquid tank and the wall of the transmission pipe. If it is not cleaned for a long time, it will cause blockage and cause the transmission pump outlet pressure value to be too large, which has certain safety hazards and affects the water quality.

In addition, when the transmission pump transfers the solution in the mixing tank to the clarified liquid storage tank, the clean water branch cleans the mixing tank and the clarified liquid storage tank; then close the valves of the clean water branch, the transmission pump and the dosing pump, and open the conical bottom drainage port of the storage tank and the mixing tank to discharge the waste liquid generated by descaling.
