Disclosed is a depositing apparatus for forming a thin film, the apparatus including a source container in which a source material to be deposited on a substrate is accommodated in a solid or liquid state; an evaporation chamber which couples and communicates with the source container above the source container, and through which an evaporated source material from the source container passes; a spraying hole which is formed on a top of the evaporation chamber, and sprays upward the evaporated source material passed through the evaporation chamber; a first heater which is provided above the source material inside the evaporation chamber or the source container, and supplies heat to the source material to evaporate the source material accommodated in the source container; and a block plate which is provided above the first heater inside the evaporation chamber, and prevents the source material or foreign materials contained in the source container from being sputtered and attached to the spraying hole while the first heater supplies heat to the source material.

A solar water evaporation purification and decomposition device comprises a water supply line, a floating and heat insulating layer, an evaporation layer, a light-to-heat conversion and a solute blocking layer connected sequentially from bottom to top. The water supply line uses capillary action to pump water through the floating and thermal insulation layer to the evaporation layer. The light-to-heat conversion and solute barrier layer absorbs solar energy and converts it into heat, and the heated water is vaporized from the evaporation layer to water vapor. Through the light-to-heat conversion and solute barrier The pores of the layer are volatilized, and part of the water vapor is decomposed to produce hydrogen and oxygen. Since the light-to-heat conversion and solute barrier layer contains hydrophobic parts, it will not be infiltrated by water, so solar energy can only directly heat the heat-absorbing material without heating water to achieve high light intensity. Heat conversion efficiency, while preventing solutes in water from being precipitated on the surface of the membrane, to achieve seawater desalination, sewage purification and water splitting. The invention obtains a solar water evaporation purification and decomposition device with high light-to-heat conversion efficiency and high stability through the design of a hydrophilic / hydrophobic double-layer evaporation structure.

The invention relates to a pipe type falling film evaporator, and provides a horizontal pipe type falling film evaporator. An evaporation chamber, a distribution cavity and a recycle cavity of the falling film evaporator are mutually isolated closed cavities; condensation pipe bundles are horizontally arranged in the evaporation chamber and used for communicating the distribution cavity and the recycle cavity; a film distribution device is located above the condensation pipe bundles; a concentrated solution outlet is formed in the bottom of the evaporation chamber; condensed water outlets are formed in the bottom of each of the distribution cavity and the recycle cavity; a vapor inlet pipe for communicating the outside and the distribution cavity is arranged, a vapor outlet pipe for communicating the outside and the evaporation chamber is arranged, and a foam destroyer is arranged in the steam outlet pipe. According to the horizontal pipe type falling film evaporator, closed and mutually isolated cavities are formed, so that the stability of an evaporation process, secondary steam and heating steam supply are guaranteed, and the horizontal pipe type falling film evaporator is suitable for MVR (mechanical vapor recompression) vaporization system.
