Abstract: To provide a solvent separator for purifying an exhaust atmosphere efficiently in solvent removal from the exhaust atmosphere containing a vaporized solvent by the heating exhausted from an exhaust generator, so that the vaporized solvent does not slip through an electrode for collecting the solvent and is positively led to the electrode. An electrode is arranged in a first wall surface of a casing of a solvent separation unit having a circular cylindrical shape, thereby inducing a vaporized solvent in an exhaust atmosphere to the electrode by a fan and discharging the solvent to the outside of the separator with part of the peripheral exhaust atmosphere while attracting the solvent to the electrode by an electric field of the electrode.

Abstract: A method and an apparatus for collecting flux in a way that improves the cleanliness inside a furnace by improving flux collection efficiency, reduces flux viscosity to maintain a liquid state even at ordinary temperature, and makes the flux collection unit more easily serviceable includes a rosin particle contained in an atmosphere gas, and vapor of a solvent or an atomized solvent particle are mixed in a mixing section provided upstream of a flux collection unit-side inlet, and a gas containing a mixed particle is cleaned by means of electrostatic precipitation. The solvent particle adheres to the rosin particle, and forms an aggregate of large particle size that can be more easily charged by corona discharge. This improves the flux collection rate of electrostatic precipitation collection, and, because the rosin particle dissolves in the solvent particle, the collected flux can have reduced viscosity.

Abstract: In a vapor-phase type heating method, an object is heated by a heated gas containing vapor in a heating furnace. The heat transfer fluid falling from a front surface of the object to a lower portion of the heating furnace is collected, after the vapor comes into contact with the object and cools to liquefy and latent heat of vaporization of the vapor is applied to the object through phase change. The heated gas obtained after heating the object is discharged from an inside of the heating furnace to the circulation route. In the circulation route, the heat transfer fluid is supplied as droplets to the discharged heated gas and is vaporized after heating, and the heated gas including the vapor is supplied to the heating furnace.
