Abstract

The embodiment of the invention discloses jet evaporation vapor phase drying equipment. The jet evaporation vapor phase drying equipment comprises an evaporator module. The evaporator module is arranged outside a vacuum tank. The evaporator module adopts a plate type heat exchanger to realize heating and evaporation treatment of a liquid solvent, so that the liquid solvent reaches an over-heat supersaturated state, the liquid solvent enters the vacuum tank through a main spray pipeline and is sprayed out from a plurality of preset nozzles, jet evaporation is formed, and a transformer in the tank is heated; and venturi baffles are arranged at the front portions of the nozzles. By the adoption of the jet evaporation vapor phase drying equipment, the drying treatment efficiency of transformerproducts is improved, the drying time is shortened, the energy consumption is reduced, and meanwhile, the adopted plate type heat exchanger is small in size and higher in heating efficiency.

Description

technical field [0001] The embodiment of the present invention relates to the field of transformer mechanical equipment manufacturing, in particular to a spray evaporation vapor phase drying equipment. Background technique [0002] Vapor-phase drying technology belongs to the drying technology of phase-change heat, which is mostly used in the drying treatment of transformers with voltage levels of 110kV and above. At present, the vapor-phase drying technology uses kerosene vapor as the heat-carrying medium and uses phase change as the main heat transfer form to dry transformer products. It is a treatment method to remove moisture from transformer insulating materials. Vapor phase drying technology has undergone great changes since it was used in the 1970s. However, with the rapid development of high technology, the existing vapor phase drying equipment and technology are still relatively backward. Existing vapor-phase drying equipment and technology exist that kerosene eva...
