Electric heating pool for generating bubbles with fixed sizes

Abstract

The invention belongs to the technical field of liquid heating, and particularly relates to an electric heating pool capable of generating bubbles with fixed sizes. The electric heating pool comprisesa stainless steel pool and a water supplementing tank, wherein the stainless steel water tank is arranged on an electromagnetic heater and is connected with the water supplementing tank through a pipeline; an electric valve A is arranged on a connecting pipeline of the stainless steel water tank and the water supplementing tank; an annular metal tray is welded to the upper portion of the stainless steel pool; and a metal grid is placed on the metal tray. According to the invention, the sizes of bubbles passing through the grid can be controlled by changing the size of the metal grid near a liquid level, so the sizes of the bubbles reaching the liquid level are fixed; by adjusting the structure of the bottom of the pool and using bases of different shapes and specifications, the positionsand the number of the bubbles can be changed; and an aqueous solution is continuously supplied to the electric heating pool through a temperature-controllable water storage tank, so the electric heating pool can maintain a constant liquid level, and bubbles are continuously generated.

Description

technical field [0001] The invention belongs to the technical field of liquid heating, and in particular relates to an electric heating pool for generating bubbles of fixed size. Background technique [0002] At present, the electric heating pools on the market mainly use electromagnetic heating and resistance wire heating. When the aqueous solution is heated to boiling, a large number of bubbles will be generated. [0003] The bubbles grow from small to large, because a small amount of air is dissolved, and air is also adsorbed in the small cavities on the surface of the container wall. These small bubbles act as gasification nuclei. [0004] The solubility of water to air and the adsorption capacity of air on the wall of the vessel decrease with the increase of temperature. When water is heated, air bubbles first form on the walls of the container. [0005] After the bubbles are generated, the container wall inside the pool is actually in a "dry burning" state, while the...

Problems solved by technology

[0008] For the traditional electric heating pool, when the aqueous solution is heated to boiling, there is a large difference in the size of the bubbles when the bubbles rise to the liquid surface, and the size of the bubbles cannot be controlled; at the same time, the bubble output when the traditional electric heating pool boils cannot meet the demand.
