Vacuum heat pump type distilling apparatus

Abstract

The invention discloses a vacuum heat pump type distilling apparatus which comprises a program controller, an evaporating tank assembly, a condensing tank assembly, a distilled water tank assembly, a vacuum buffer tank assembly, a vacuum pump, an air inlet pipe of the vacuum pump, an air exhaust hole of the vacuum pump, an electrical bar, a compressor, a high-temperature condenser, a low-temperature evaporator, a compressor outlet pipeline, a compressor inlet pipeline, a connecting pipe and a throttling valve. In the invention, first, the vacuum pump is used for pumping the device into a vacuum state so that the boiling temperature of the water is lowered and the heat pump can meet the temperature requirement; then, the low-temperature evaporating pipe of the heat pump is used for absorbing the energy of high-temperature steam to heat the water; and meanwhile, after the heat of the high-temperature steam is absorbed, the high-temperature steam is condensed into distilled water, the cooling process of the high-temperature steam can not consume any tap water, the power can be saved by more than 80%, and the water can be saved by more than 90%. In order to solve the problem that the heat source is insufficient when the heat pump is just started, the electrical bar is used for heating the water to the specified temperature in the starting process.

AI Technical Summary

Problems solved by technology

[0004] In addition to drinking, distilled water is also widely used in electroplating industry, pharmaceutical industry, food processing industry, wine making industry, beverage industry and other industries, because distilled water not only consumes a lot of electric energy under the current process conditions, but also consumes a lot of cooling water , so the price is more expensive,
