Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
After adding pure water to the hot water kettle in which scale is present, the hot water kettle is heated, and the pH value of the hot water kettle gradually decreases as the temperature of the pure water increases, as shown in fig. 1. This phenomenon occurs because as the temperature increases, the ionization equilibrium constant Kw of water increases, and [ H ] in water+]And [ OH-]Will increase due to [ H ]+]The pH thereof is decreased, so that the scale is gradually disappeared.
As shown in fig. 2, the heating module pollution-free descaling structure in the present embodiment comprises a water filtering module 7, a heating module 1 and a controller 10, wherein the water filtering module 7 has a water inlet end, a pure water outlet end and a wastewater outlet end, and the water inlet end is provided with a first electromagnetic valve 21; the water filtration module 7 in this embodiment includes a primary filtration assembly 71, a booster pump 72, and a reverse osmosis membrane filter 73, which are connected in sequence, wherein the primary filtration assembly 71 is composed of PP cotton and activated carbon. The waste water outlet end of the water filtering module 7 is provided with a waste water ratio 8.
Heating module 1 has first water inlet, second water inlet, waste water export and delivery port, and first water inlet is equipped with second solenoid valve 22, and the second water inlet is connected with the pure water play water end of water filtration module 7, and the waste water export is equipped with third solenoid valve 23, and the delivery port is equipped with fourth solenoid valve 24, is equipped with temperature sensor 3, TDS sensor 4 and level sensor 5 on this heating module 1.
