Description

Technical Field

[0001] The invention relates to the technical field of water purifier production and concentration, and in particular to a solution concentration device for water purifier. Background Art

[0002] The water purifier has the characteristics of good water purification effect, fast water purification speed, weak acidic pH, inorganic, high safety, and no secondary pollution. It is a green and environmentally friendly product. It uses natural materials with adsorption capacity as raw materials. It has a strong purification effect and can remove heavy metals in the water. The treatment of raw water is not affected by water temperature and pH value. It has a wide range of uses. The treated water is extremely transparent and can be reused. It can react with impurities in the water, and the impurities can be flocculated, precipitated, and even separated to make the water clear.

[0003] After searching, it was found that the application number is CN202111565405.6, and the name is a high-efficiency water purifier preparation system and preparation method. The application discloses a method for preparing a liquid polyaluminum chloride solution water purifier, which includes concentrating and drying the liquid polyaluminum chloride solution to obtain a water purifier. At this stage, the concentration equipment is roughly divided into two types. One is heating concentration, which heats the solution by a heat source to cause the water in the solution to evaporate, thereby achieving the purpose of concentration. This method consumes a lot of energy, and it is impossible to add and discharge materials simultaneously during the heating and concentration process. The working continuity is not high, the working time is long, the working efficiency is low, and it is not environmentally friendly. The other is low-temperature concentration, which uses refrigeration equipment to lower the solution temperature so that the water in the solution is in an ice crystal state, and completes solid-liquid separation with the target concentrated product, and then removes the ice crystals to complete separation and concentration. This method also consumes a lot of energy, and temperature control is very difficult. It will also cause problems such as low working continuity and long working time. The technical difficulty is high and further improvements can be made.

When the pressure is too high, the pressure-stabilizing valve 10 opens, and the water purifier solution after preliminary concentration enters It enters the second diverter disk 12 and is sprayed along the atomizing nozzle 13. At the same time, the hot air generator 21 generates hot air, which is blown upward through the gas distributor disk 15 and the air outlet pipe 16, and quickly contacts with the atomized and falling water purifier solution, evaporates the water in the water purifier solution, and completes the secondary concentration. The device uses the atomized water purifier solution and the hot air to complete rapid heat exchange to evaporate and concentrate the water. The heat exchange efficiency is high, the evaporation speed is fast and uniform, the speed is faster, the efficiency is higher, the working continuity is higher, and the working efficiency is further improved. At the same time, the water collector 11 is installed above the second diverter disk 12 to prevent the liquid water purifier solution from passing through. The steam enters the steam dehydrator 23 through the exhaust pipe 14, and returns to the hot air generator 21 after dehydration, utilizing the waste heat of the steam, which is convenient for the hot air generator 21 to quickly perform secondary heating, with lower energy consumption, and further improving the environmental protection and energy saving efficiency.
