Will be described with reference to FIG.

The venturi tube 200 includes an inlet tube 220 and a discharge tube 240. It is to be understood that the venturi tube 200 may be any type of venturi tube for rapid discharge of exhaust gas. Preferably, the inlet pipe 220 may be formed so that the inner cross-sectional area of the inlet pipe 220 decreases from one end of the inlet pipe 220 to the other end of the inlet pipe 220 at the outlet of the outlet pipe 220, Sectional area of the discharge pipe 240 may be reduced from one end of the discharge pipe 240 at a point where exhaust gas is discharged to the outside of the discharge pipe 240 toward the other end of the discharge pipe 240.

The other end of the inflow pipe 220 and the other end of the discharge pipe 240 are in contact with each other.

A circulating gas flow space 320 through which a circulating gas is supplied from a circulating gas supply unit 720 to be described later is formed at a portion where the other end of the inlet pipe 220 and the other end of the discharge pipe 240 are in contact with each other, A circulating gas flow hole 340 communicated with the inside of the venturi pipe 200 may be formed so that the circulating gas is supplied in a flow direction of the exhaust gas discharged to one end of the inlet pipe 220 in a state of being communicated with the venturi pipe 200.

The shape of the inflow pipe 220 and the discharge pipe 240 and the coupling portion therebetween, the space-regulated circulation gas flow space 320 formed in the coupling portion, and the coupling structure of the circulation gas flow hole 340 are disclosed in Applicants' As already disclosed in the prior art, detailed description is omitted.

The air blower unit for an exhaust gas according to the present invention includes a heating unit (400) for applying heat to the discharge pipe (240). The heating unit 400 may be in any form capable of transferring heat to the inside of the discharge pipe 240, but may be in the form of surrounding the outer peripheral surface of the discharge pipe 240. The heating unit 400 heats the discharge pipe 240 to dissolve the powder to minimize the accumulation of the powder. The accumulated powder is heated and suspended to be discharged together with the educt gas. Further, the accumulated powder is discharged through the discharge pipe 240, It is possible to minimize sticking to the inner surface.

The air blower unit for an exhaust gas according to the present invention includes a magnetic body part (500) which exerts a magnetic force on an exhaust gas passing through the discharge pipe (240) while surrounding the outer circumferential surface of the discharge pipe (240). The magnetic body part 500 may be located outside or inside the heating part 400, but it is preferably located outside the heating part 400. Details will be described later.

The air blower unit for exhaust gas according to the present invention is installed in the venturi pipe 200 and communicates with the venturi pipe 200. The air blower unit measures the air flow rate, the wind speed, and the temperature of the exhaust gas passing through the venturi pipe 200 (Not shown). Details will be described later.

Will be described with reference to FIG.

The magnetic body part 500 surrounding the discharge pipe 240 may be a magnetic body made of the S-S poles, unlike the magnetic body made of the general N-S poles. That is, it may be a magnetic substance composed of an S-pole single pole. The exhaust gas flows to the discharge pipe 240 surrounded by the magnetic body part 500 and receives the magnetic force of the magnetic body part 500.

The exhaust gas flowing into the discharge pipe 240 is subjected to a strong S-S polar magnetic force acting vertically in the discharge pipe 240. In other words, the magnetic force due to the S pole is applied to the center of the discharge pipe 240 in all directions. As a result, the exhaust gas flowing into the discharge pipe 240 is a strong S The magnetic force of the pole is received.

It is known that the magnetic force of the SS polar magnetic body is 3,000 to 5,000 Gauss, but the magnetic force of the SS polar magnetic body is 11,000 Gauss or more. It is known that the magnetic force of the SS polar magnetic body can be increased up to 500 times the magnetic force of the maximum N-S polar magnetic body.

It is known that a negative charge, which is affected by magnetic force, passes through a strong magnetic force formed by the SS pole and is converted into a positive charge uniformly. Thus, an exhaust gas containing a molecule having a predetermined negative charge, The exhaust gas containing only positively charged molecules is discharged to the exhaust gas discharged to one end of the discharge pipe 240 as the molecules having such a predetermined negative charge are changed into positive charges due to the strong magnetic force of the magnetic body part 500.

The magnetic body unit 500 may be any magnetic body made of the S-S poles having a strong magnetic force, but may be a magnetizer made of S-S poles manufactured using a ferrite magnet, for example.

As shown in FIG. 3, as a result, the exhaust gas containing the negatively charged molecules flows into the discharge pipe 240 and is converted into a positive charge. As a negatively charged molecule is converted into a positive charge, The bonding force is weakened, so that powder accumulation and sticking that may occur on the inner side of the discharge pipe 240 can be minimized.

Further, since the exhaust gas discharged from the discharge pipe 240 is exhaust gas containing only positively charged molecules, scale generation in the exhaust gas pipe can be minimized in a state in which the ion binding force is weakened.

In the air blower unit for an exhaust gas according to the present invention, a plurality of protrusions 222 protruding toward the inner center direction are formed on the inner side surface of the inflow pipe 220. The protrusion 222 extends in the longitudinal direction from one end of the inflow pipe 220 to the other end, and may extend in a curved shape.

The height of the protruding portion 222 may be lowered toward the other end of the inflow pipe 220 where the exhaust gas flows from one end of the inflow pipe 220 at which the exhaust gas flows, 222 at the top of the inflow pipe 220. In this case,

The exhaust gas flowing into the inlet pipe 220 is rapidly discharged and a vortex is generated in the exhaust gas discharged from the inlet pipe 220 so that the powder accumulation in the inlet pipe 220 and the outlet pipe 240 And easily removes the accumulated powder by using a vortex of the exhaust gas generated due to the flow of the exhaust gas due to the formation of the plurality of protrusions 222 even if a small amount of powder is already accumulated.

That is, the exhaust gas flowing into the inflow pipe 220 rapidly flows into the inflow pipe 220 due to the pressure difference generated according to the flow velocity difference of the exhaust gas inside the venturi pipe 200, Flows into the curved shape formed between the projecting portion 222 and the projecting portion 222 as well as the central portion of the inlet pipe 220 to form a vortex in the entire flow of the exhaust gas, The powder accumulation on the inner side of the inflow pipe 220 and the discharge pipe 240 is prevented.

4 is a view showing a state in which the protrusion 222 is formed on the inner side of the inflow pipe 220. FIG 5 is a cross-sectional view of the inflow pipe 220, And then flows into the discharge pipe 240 in a state where the gas is vortexed, and flows through the discharge gas to the outside.
