Description

Multi-Purpose Vertical Mixing Dissolver {MULTI-PURPOSE MIXING DISSOLVER}

The present invention relates to a multipurpose vertical mixing dissolving machine used for mixing gas and liquid or liquid and liquid in a wastewater treatment plant, water treatment plant, hydroponics, fish farm, industrial site, etc. The present invention relates to a multipurpose mixed dissolver invented to increase the mass transfer rate as much as possible by maximizing a mixed performance of a gas and a liquid, a liquid and a liquid by forming a diaphragm laminated with a diaphragm.

In the past, fish farms and water treatment plants mainly increase the amount of oxygen in the water by means of an aeration device or oxygen supply device. However, in this case, oxygen is supplied to the water and bubbles are floated and deaerated into the atmosphere. There was a problem that the dissolved dissolved oxygen present.

A vertical mixer for solving this problem is disclosed in Korean Patent Laid-Open Publication No. 2000-0018208. The disclosed vertical mixing dissolver is a mixture of liquid and gas is made in the process of the gas supplied with the liquid from the upper portion of the vertical mixing dissolver body to the bottom, and constitutes a gas dispersion mixing dissolver body upper dispersion diffuser The first gas dissolved in the grill layer and dissolved by dropping is bubbled and flows down from the top to the bottom according to the flow of the fluid, and then floats upward by the buoyancy of the bubble at a certain point.

In addition, the liquid and gas continuously flowing through the repetitive process, a constant gas-liquid space portion is formed on the water surface in proportion to the hydraulic pressure, the flow rate, and the gas gas amount in the mixed solvent. In this process, the undissolved gaseous gas continuously moves to the upper and lower parts according to the hydrodynamic structure, and is ultra-fine and forced to dissolve due to the increase in surface area and frictional force.

However, such a conventional vertical mixing solvent has a relatively long vertical length, and thus cannot be transported and installed as a set unit, so that it is decomposed into a plurality of parts and transported to an installation site, and the transported majority Part of the assembly had to be installed as a set unit.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a multipurpose vertical mixing dissolver having a vertical length of a main body shorter than that of the conventional body without impairing mixing and dissolution efficiency.
