Energy-saving water purification machine

Abstract

The invention relates to an energy-saving water purification machine in the field of water purification devices. The energy-saving water purification machine comprises a distillation tank. A tap water inlet and a steam outlet are formed in the distillation tank, and a first electrical heated tube and a heat exchanger are arranged inside the distillation tank; a vacuum pump, a hot water tank and an ice water tank are arranged on the left side of the right side of the distillation tank, a second electrical heated tube is arranged inside the hot water tank, an inlet pipe of the vacuum pump is connected with the steam outlet in the distillation tank through a first electromagnetic valve, an outlet pipe of the vacuum pump is connected with an inlet pipe of the heat exchanger, and an outlet pipe of the heat exchanger extends upwards along the inner wall of the distillation tank and is communicated with the hot water tank; the back portion of the ice water tank is connected with an inlet in the vacuum pump through a third electromagnetic valve; a fourth electromagnetic valve is installed above the ice water tank, and the left side of the ice water tank is communicated with a vertical pipe arranged on the inner wall of the hot water tank through a second electromagnetic valve. According to the energy-saving water purification machine, heat emitted when air pressure is reduced to evaporate steam and steam is cooled into water is used, electric energy required by 1-kg purified water is 0.1 degree, energy is saved, environment protection is achieved, and the energy-saving water purification machine has the popularization value.

Description

technical field [0001] The invention relates to the field of water treatment equipment manufacturing, in particular to an energy-saving pure water machine developed by adopting the principle of natural evaporation. Background technique [0002] The earth's water pollution is mainly caused by pollutants produced by human activities, including industrial pollution sources, agricultural pollution sources and domestic pollution sources. Water pollution has posed a major threat to human survival and has become a major obstacle to human health and social development. [0003] Most waterworks at home and abroad still use the outdated process of sedimentation, filtration, and chlorine disinfection to simply process river water or groundwater into potable water. In the face of a large number of industrial and agricultural pollution sources pouring into domestic water sources, the types of pollutants are increasing, and the waterworks are unable to remove all pollutants.

Problems solved by technology

[0005] The traditional pure water machine uses membrane filtration to obtain pure water. Because the membrane is easy to plug, it is not easy to maintain, and the replacement cost is high. In addition, the membrane filtration process requires a large pressure, and the energy consumption of pressurized filtration is also high.

Therefore, citizens generally buy bottled purified water to meet the demand for drinking water, but the cost of purchasing bottled purified water is relatively high, and the price per 1 kg of water exceeds 1 yuan, and the bottled purified water is due to supply and distribution. The channels are difficult to manage, and the bacteria often exceed the standard and fail to meet the standards. Unscrupulous merchants use untreated tap water and sell it as pure water, which seriously damages the health of the citizens.
