[Ca-based waste input step] ----- S1

This phase is the step of inputting Ca waste which is used in industrial field and environmental field and discarded, and most of it is put into gas form, powder form or sometimes solid form.

In the case of the solidified form as described above, the solidified Ca-based waste is transported and crushed by a screw or the like before the mixing and stirring step (S3) to be described later, and is then pulverized (S2) may be added.

[Mixing Stirring Step] ----- S3

The added Ca-based waste is transferred to a mixing tank (T), and water is added thereto, followed by stirring and mixing with an agitator (M). As a result, calcium hydroxide is mostly produced when the Ca-based waste and water are combined.

[Stirring storage step] ----- S4

After the mixing and stirring step (S3), the mixture is stirred again and transferred to the carbon dioxide removing step (S5) described below.

[Carbon dioxide removal step] ----- S5

After the stirring and storing step (S4), there is provided a reaction tank (200) for removing carbon dioxide introduced by the blowing means (100)

As shown in FIGS. 5 to 7, in the carbon dioxide removing step (S5)

A blowing means 100 for supplying carbon dioxide,

And the reaction tank (200) connected to one end of the blowing means (100)

The reaction tank 200 is provided with a connecting portion 110 connected to the blowing means 100 at a lower end and a Ca-based waste mixed with water transferred from the stirring and storing step S4 is introduced into the pump P, And a plurality of injection tubes 210 crossing the inside of the upper end of the reactor 200 so as to be multi-stage injected after being upwardly flowed by the filter unit 220 in the upward direction, And a direct water distribution pipe 230 for directing the water on the filter part 220 and washing the filter part 220. The water discharge pipe 230 for discharging carbon dioxide is provided on the direct water distribution pipe 230, (240) is formed,

The connection unit 110 forms a header pipe 130 connected to the main pipe 120 of the blowing unit 100. A plurality of branch pipes 131 are connected to and protrude from the header pipe 130, A plurality of water immersion pipes 132 connected to each other in the vertical direction for each of the one branch pipe 131 are formed so as to pass through the inside of the reaction tank 200, It is a structure that allows it to flood with waste.

Meanwhile, the branch pipe 131 has a structure in which the inner diameter of the branch pipe 131 gradually decreases from the header pipe 130,

Preferably, the water immersion tube 132 has the same diameter.

The connection unit 110 forms a header pipe 130 connected to the main pipe 120 of the blowing unit 100. A plurality of branch pipes 131 are connected to the header pipe 130, And allowing the carbon dioxide to flow into the reaction vessel 200 through the reaction vessel 200,

More preferably, as shown in FIG. 4, a plurality of reaction vessels 200 are formed.

According to the present invention configured as described above, the carbon dioxide is introduced into the reaction tank 200 side by the blowing means 100, and after the reaction between the Ca-based waste mixed with the water supplied from the stirring and storing step S4 and the carbon dioxide , And then flows upward to the upper part of the reaction tank 200 to be discharged.

The produced calcium carbonate (CaCo 3) in combination with the CO 2 Calcium hydroxide (Ca (OH) 2) is a most for a Ca-based waste, CO 2 removed the water mixture to be supplied from the stirring storing step (S4) . This will be described later.

Meanwhile, the blowing means 100 is provided as a means for introducing carbon dioxide into the reactor 200 side.

As shown in the drawing, the blowing means 100 adopts a connecting portion 110 for connecting the blowing fan to the reaction tank 200 to introduce carbon dioxide into the reaction tank 200, A header pipe 130 connected to the main pipe 120 of the blowing means 100 is formed and a plurality of branch pipes 131 are connected and protruded from the header pipe 130, A plurality of water immersion pipes 132 connected to each of the branch pipes 131 in the vertical direction are formed so as to be submerged in the Ca-based wastes mixed with the water stored in the reaction tank 200.

That is, the main pipe 120 connected by flange connection from the blowing means 100 has a header pipe 130 connected to the main pipe 120 in an orthogonal direction.

The speed and flow rate of the fluid flowing through the header pipe 130 and the main pipe 120 should be designed to be the same.

A branch pipe 131 is separately formed from the header pipe 130 so as to pass through the inside of the reaction tank 200.

Here, as shown in the figure, the branch pipe 131 is preferably formed to be smaller in steps as its diameter moves away from the header pipe 130.

That is, when the fluid pressure, the flow rate and the flow rate of the carbon dioxide supplied from the blowing means 100 pass through the main pipe 120 and the header pipe 130 as well as to the end of the branch pipe 131, This is because the effect of reaction with the Ca-based waste mixed with water stored in the reaction tank 200 can be enhanced.

The flood pipe 132 is connected to the lower end of each of the branch pipes 131 by an equal distance and is connected in an orthogonal form so that the flooded pipe 132 can be submerged into the Ca-based waste mixed with the water stored in the reaction tank 200. Respectively.

Each of the water immersion pipes 132 here has the same diameter.

The carbon dioxide is guided from the main pipe 120 of the connection part 110 to the header pipe 130 and then branched from the header pipe 130 by the operation of the blower 100. Thus, The water stored in the reaction tank 200 is submerged in the Ca-based waste, and the carbon dioxide is discharged to the side of the submerged pipe 132 through the submerged pipe 132, And to react with water mixed with Ca-based waste.

The reaction at this time is made with calcium hydroxide (Ca (OH) 2 ), and the reaction formula is as follows.

Ca (OH) 2 + CO 2 -> CaCO 3 + H 2 O

The connecting portion 110 of the blowing means 100 may be configured differently from the header pipe 130 connected to the main pipe 120 of the blowing means 100, (131) are connected to and protrude from the reaction tank (200), and carbon dioxide can be introduced into the reaction tank (200) through the reaction tank (200).

The branch pipe 131 penetrates through the reaction tank 200 without passing through the submerged pipe 132 in the form of the above-described submerged pipe 132, but is configured to pass through the pipe in a state close to the inner peripheral surface of the reaction tank 200.

Accordingly, when such a structure is provided, the carbon dioxide introduced from the blowing means 100 is supplied to the lower end of the reaction tank 200, and the reaction occurs while colliding with the surface layer of the Ca-based waste water mixed with water.

Meanwhile, in the stirring and storing step (S4), a multi-stage injection is performed after bypassing upward flow by a pump (P).

That is, the Ca-based waste mixed with the water to be supplied and supplied to the reaction tank 200 from the stirring and storing step S4 is bypassed upward in accordance with the operation of the pump P, To the lower side of the reaction tank 200 through the spray pipe 210 across the reaction tank 200.

Here, the injection pipe 210 may be formed in multiple stages in the upper and lower portions of the reaction tank 200 as shown in the drawing.

Therefore, the Ca-based waste mixed with water flowing by bypass to the injection pipe 210 is sprayed downward from the upper side of the reaction tank 200 and falls down naturally. The carbon dioxide stored and raised in the lower part of the reaction tank 200, Reaction.

That is, due to the hydraulic pressure and the flow rate of carbon dioxide, it is impossible to sufficiently react with the Ca-based waste mixed with water. To solve this problem, the gas phase carbon dioxide forcedly supplied into the Ca- And is convected upward toward the upper side of the reaction tank 200. In the convection process, a gas in which the carbon dioxide is not completely removed and water that falls through the injection pipe 210 side is mixed The carbon dioxide can be completely removed through re-reaction with the Ca-based waste.

In addition, since the injection tube 210 can be equally spaced apart from the proper position, it is possible to increase the removal efficiency of carbon dioxide.

The filter unit 220 is provided on the injection pipe 210 so that impurities or water contained in the carbon dioxide can be filtered and intermittently supplied to the filter unit 220 And the water distribution pipe 230 for cleaning the filter unit 220 is provided.

In addition, a discharge pipe 240 for discharging carbon dioxide is formed in the direction of the direct flow water distribution pipe 230 so that the rising carbon dioxide is discharged to the outside through the above-described process.

[Calcium carbonate storage step] ----- S6

After the carbon dioxide removing step (S5), the liquid calcium carbonate that is pumped and stored by the pump (P) is stored.

The liquid calcium carbonate thus stored is mixed with raw materials for various applications, for example, as a building material, or used as a raw material for producing other products.

[Calcium carbonate dehydration step] ----- S7

On the other hand, when calcium carbonate in a liquid state is not used and the user desires calcium carbonate in a gel state, the calcium carbonate in the liquid phase is pumped by the injection pump P1 as in the present step so that the dehydrated gel- It can be made of calcium carbonate and can meet the needs of users. It can also be used as a raw material for manufacturing desirable products mixed with various building materials and other raw materials of products.

[Calcium carbonate drying step] ----- S8
