Apparatus for producing microbubble liquid and device for atomizing air bubbles using the same

An apparatus for producing a microbubble liquid containing microscopic gas bubbles, comprising:

• a liquid feeding pipeline;
• a pressure pump arranged on the liquid feeding pipeline for aspirating liquid from a liquid supply source and forcibly feeding the liquid by pressure;
• an air bubble liquid producing means disposed on the liquid feeding pipeline on an upstream side of the pressure pump relative to a liquid feeding direction for producing the air bubble liquid by mixing the liquid with air by an aspirating pressure generated by the pressure pump;
• a first air-bubble atomizer disposed on the liquid feeding pipeline on a downstream side of the air bubble liquid producing means relative to the liquid feeding direction for atomizing air bubbles contained in the air-mixed liquid produced by the air bubble liquid producing means;
• a second air-bubble atomizer disposed on the liquid feeding pipeline on the downstream side of the first air-bubble atomizer relative to the liquid feeding direction for further atomizing the air bubbles atomized by the first air-bubble atomizer, wherein the first air-bubble atomizer is arranged between the air bubble liquid producing means and the pressure pump, and the second air-bubble atomizer is mounted on the liquid feeding pipeline on the downstream side in the liquid feeding direction of the pressure pump;
• and
• a pressure stabilizing tank disposed on the liquid feeding pipeline between the pressure pump and the second air-bubble atomizer.
