In order to eliminate liquid accumulation occurring between a gas-liquid mixing part and a vaporization part to stably perform liquid feeding to the vaporization part and vaporization in the vaporization part, a liquid material vaporization apparatus includes: a gas-liquid mixing part adapted to mix a liquid material and gas to produce a gas-liquid mixture; and a vaporization part adapted to heat the gas-liquid mixture to vaporize the liquid material. In addition, the gas-liquid mixing part has a gas-liquid mixture lead-out pipe for leading out the gas-liquid mixture, the vaporization part has a heating flow path HS for heating the gas-liquid mixture, and a lead-out port of the gas-liquid mixture lead-out pipe is arranged in the heating flow path HS.

Provided are a method for crushing hard tungsten carbide (WC) scraps which is a pre-step of alkaline leaching and acid leaching processes for recycling of tungsten and cobalt, the method including mixing hard tungsten carbide (WC) scraps such as chips, wires, bolts, drills, etc., that are metalworking tools to be discarded after being used, with aluminum, followed by heating to a high temperature, to form an intermetallic compound, metal oxides, or mixtures thereof in a sponge form, and crushing the intermetallic compound, the metal oxides, or the mixtures thereof in a sponge form. Further, provided is a method for recovering tungsten and cobalt from hard tungsten carbide (WC) scrap powder through alkaline leaching and acid leaching methods,
摘要:
Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 μm. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).
