Abstract

PROBLEM TO BE SOLVED: To obtain the multi-static mixing system utilizable in the effective areation, chemical treatment of malodor, heating, cooling, floatation, or the like in the lake, river, water supply, sewerage, fish farm, or the like by mixing liq. and gas, and liq., liq. and powder ant liq. and solid. SOLUTION: A multi-static mixer A and a pressure tank B are provided to purify the water in the lake, river, water supply, sewerage, fish farm, etc. A pump 1 is connected to the inlet A2 of the mixer A to introduce waste water, the water in a fish farm, or the like. Meanwhile, a pump 2 is connected to a suction port 5 provided on one end of the mixer A to suck liq. and chemicals. The water, chemicals, or the like, are mixed by the element A4 of the mixer A and then pressurized in the pressure tank B. In this case, the contact time is prolonged in the pressure tank B by the lowering of flow velocity due to increase in the cross-sectional area of the tank, hence the solubility of gas is increased, the water is effectively aerated, and the malodor is chemically treated.

2. Description of the Related Art In an existing wastewater treatment plant, as an example, as one process for purifying wastewater, aerobic bacteria may be cultured in a wastewater tank. In order to cultivate aerobic bacteria more efficiently, a separate air injection device (eg, a diffuser or aerator) is installed to supply oxygen and air. In addition, the amount of dissolved oxygen in wastewater is increased, and liquids and chemicals are introduced during wastewater treatment.

[0003]

However, during wastewater treatment,
There is no special charging device for liquids or chemicals, and it is artificially charged into the wastewater tank from outside. However, mixing is not performed smoothly and the interface (liquid and liquid that are not mixed, or liquid There is a problem that the regeneration rate is lowered.

[0004] In the case of an existing fish farm, the water in the fish farm is cultured with aerobic bacteria in a separate filtration tank or filtration path, and the water is filtered and, at the same time, a blower or a combiner is connected to the water. However, this also has the problem that the efficiency cannot be maximized when mixing oxygen and water or chemicals and water because water and oxygen are partially mixed.

[0005] The present invention has been made in view of the above points, and aims at liquid and gas,
Mixing liquids and liquids, liquids and powders, liquids and solids, etc. for effective aeration and chemical treatment of odors, heating, cooling and pressure flotation in lakes, rivers, water and sewage systems, fish farms, etc. An object of the present invention is to provide a multi-starty mixing system which can be used.

[0006]

In order to achieve the above object,
The multistar mixing system of the present invention
By mixing the liquid pumped into the wastewater or the fish farm with the first driving force together with the fluid drawn from the second driving force in the multi-starting mixer, it is more effective than the single-starting mixer. One of the features is to increase the contact surface area.

In addition, the multi-star mixing system of the present invention increases the contact efficiency between gas and liquid in a pressurized tank, more efficiently supplies oxygen to a wastewater treatment plant or a fish farm, etc. In the case of gas and chemicals, wastewater in the tank or water from the fish farm can be mixed in a short time,
Mixing liquid and powder, liquid and solid, liquid and solid, and liquid and gas by mixing the liquid and powder, liquid and solid, As it is supplied, it can be used throughout the industrial structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, two embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the first embodiment, as shown in FIG. 1, the multi-starting mixer (A) and the pressurized tank (B) are connected, and the first (A2) of the multi-starting mixer (A) is connected to the first (A2). A pump of driving force (1) is connected so that oxygen or air flows into wastewater or water of fish farm, etc., a suction port (5) on one side of the front surface of the outer cylinder (A1), and a second driving force.
(2) is connected to suck liquid and chemicals, mixed by the elament (A4) of the multi-starting mixer (A), and then connected so as to be pressurized by the pressurized tank (B).

In another embodiment of the present invention, as shown in FIG. 2, a multi-starting mixer (A) is installed independently, and a wastewater is pumped at an inlet (A2) by a first driving force (1). And the multi-starter mixer (A)
Liquid, gas, chemicals, etc. are sucked into the suction port (5) on the front side of the outer cylinder (A1) by the second driving force (2),
After mixing with the elament (A4) of the multi-starting mixer (A), the mixture flows into the wastewater treatment plant for purification.

In general, in a treatment method of a wastewater treatment plant, after installing a large number of aerobic bacteria culture packs in a wastewater treatment tank, oxygen is introduced, aerobic bacteria are cultured, and wastewater is purified. A filtration step is performed. At this time, an aerator or a diffuser is installed and used in order to increase the amount of dissolved oxygen in the wastewater, but the two components of the present invention configured as described above are used. Embodiments are even more effective than this diffuser or aerator. The multi increases the contact efficiency and pressurizes more than the single to dissolve more oxygen than the liquid.

That is, a multi-star-take mixer
A pump, which is the first driving force (1), is connected to the inlet (A2) of (A) so that wastewater flows in. At this time, the suction port (5)
A liquid, gas, chemical, etc., for purifying oxygen or wastewater prepared in advance is sucked into the connecting pipe (4) connected to the pipe, and the vortex is generated by a spiral repetitive motion while passing through the multi-start mixer (A). Wastewater and oxygen or chemicals swirl along a large number of elament (A4)
The fluid becomes a completely mixed fluid and is sucked into the pressurized tank (B) and compressed.

At this time, the object prepared to be sucked into the connecting pipe (4) of the suction port (5) is selectively equipped with a liquid, a gas, a chemical and the like necessary for wastewater treatment. Become like As described above, the multi-starting mixer (A) of the present invention can minimize the length while maintaining the mixing efficiency, and the divided mixing can be performed at the interface of the mixed fluid (liquid and liquid or liquid and gas, etc. which are not mixed). In the pressurized tank and the pressurized pipe, the contact time is prolonged due to a decrease in the flow velocity due to an increase in the tank cross-sectional area, and the solubility of the gas by pressurization is increased.

Accordingly, the present invention provides a multi-starter mixer as shown in FIG. 1 at the time of wastewater treatment, at the time of liquid, gas, or chemical input, or at the time of oxygen or chemical input in a water filter of a fish farm. (A) + Pressurized tank (B), or a system combining pressurized pipes can be installed. As shown in FIG. 2, the multi-starting mixer (A) can be installed and used independently. The present invention can be selectively installed so as to meet the requirements of a wastewater treatment plant or a fish farm.

[0014]

As can be appreciated from the above description, the multi-starting mixing system of the present invention has many economic benefits by mixing multiple volumes simultaneously and more efficiently for multiple purposes.
