Connected to the main body 10 and integrally formed, the upper end of the small diameter portion 10a of the main body 10 and the lower end of the large diameter portion 10b of the main body 10 are connected to the upper portion of the drain gang 10c. It is positioned and coupled to the inner side of the lower plate 20 and the lower plate 20 is formed with a plurality of through holes 21 so that contaminants or rainwater flows into the drain gang 10c and extends into the large diameter portion 10b. Baffle plate 30 to separate the contaminants during the perfusion of the exhaust gas, and on the top of the baffle plate 30 The upper plate 40 which is hermetically coupled and changes the flow of exhaust gas from the vertical direction to the horizontal direction to be led to the baffle plate 30, and is installed at the lower end of the drain gang 10c and provided to the drain gang 10c. It comprises a drain pipe 50 for discharging the introduced pollutant or rain water to the outside.

Here, the main body 10 forms a frame of the stack contaminant removing apparatus 1 according to the present invention, and the small diameter portion 10a and the small diameter portion 10a coupled to the stack 3 of the industrial environmental facility. The large diameter portion 10b located at the top height of the small diameter portion 10a and the large diameter portion 10b are connected by the baffle plate 30, which will be described later, and are collected by the pollutants falling down or rainwater falling from the top. The drain gang 10c which flows in is formed integrally.

In particular, the lower end of the small diameter portion (10a) is preferably flanged to the top of the stack (3) of the industrial environmental equipment to be hermetically coupled to each other, for this purpose, the lower end of the small diameter portion (10a) of the main body 10 and the industrial environmental equipment At the top of the stack 3 is preferably provided with flanges for mutually hermetic coupling.

The liquid collector 11 is formed at the upper end of the large diameter portion 10b of the main body 10. The liquid collector 11 has a liquid formed on the inner wall of the large diameter portion due to condensation. It serves to prevent the discharge into, it is formed in a shape similar to the step.

In addition, a drain induction pipe 13 is installed on the inner wall of the large diameter portion 10b of the main body 10, which drain guides the contaminants collected in the liquid collector 11 to the drain gang 10c. As a conduit to play a role, a plurality of pipes are provided at predetermined angular intervals around the inner wall of the large diameter portion 10b of the main body 10.

In addition, the support 15 is preferably installed on the inner upper portion of the large diameter portion 10b of the main body 10, which is the main body 10, particularly the large diameter portion 10b through which the exhaust pressure is transmitted. ) And protrudes from the large-diameter portion 10b of the main body 10 between the first support beam 15a and the first support beam 15a intersected by a cross (+). The second support beam 15b is connected to the upper plate 40 to be formed.

The upper end of the small diameter portion 10a of the main body 10 and the lower end of the large diameter portion 10b of the main body 10 are connected by the lower plate 20, and the lower plate 20 is connected to the main body 10. The small diameter portion 10a and the large diameter portion 10b of the main body 10 are connected to each other, and the pollutants falling by the baffle plate 30 and falling down to guide the rainwater falling from the upper portion to the drain gang 10c. By doing so, a plurality of through-holes 21 are formed in the upper part of the drain gang 10c so that pollutants or rainwater flows into the drain gang 10c. In addition, the lower plate 20 is formed with a step 23 for mounting and coupling the baffle plate 30 therein.

The baffle plate 30 is coupled to the inside of the lower plate 20 and extends vertically in the large diameter portion 10b. The baffle plate 30 is discharged from various industrial environmental facilities (not shown). When the exhaust gas flows through it serves to separate the contaminants contained in the exhaust gas, as shown in Figure 4, so that the contaminants contained in the exhaust gas can be easily separated during the perfusion of the exhaust gas, The corrugated baffle body 31 formed by stacking the dogs together with each other, and a wing plate 33 alternately protruding to both sides of the baffle body 31 and extending in the opposite direction of the exhaust gas flow.

The shape of the baffle plate 30 in which a plurality of corrugated baffle bodies 31 are stacked on each other and wing plates 33 are alternately protruded on both sides of each baffle body 31 changes the flow of exhaust gas in a zigzag manner. Inducing the large contaminants to directly impact the baffle plate 30 increases the collection effect of the contaminants and at the same time facilitates the collection of contaminants that are particularly respread.

In the case of the baffle plate 30, contaminants having sufficient inertia force do not follow the flow of gas, but use an inertial impaction principle attached to the surface of the baffle plate 30 in the exhaust gas during perfusion of the exhaust gas. The pollutants contained are collected and separated. The baffle plate 30 may be made of various materials such as nonwoven fabric.

In addition, the baffle plate 30 extends in the vertical direction in the large diameter portion 10b of the main body 10 in a state of being formed in a cylindrical shape having the same inner diameter as the small diameter portion 10a of the main body 10 as a whole. It is preferable that the purified air is discharged to the outside through the space between the 30 and the large diameter portion 10b of the main body 10.

The upper plate 40 is coupled to the upper end of the baffle plate 30, which is to change the flow of exhaust gas from the vertical direction to the horizontal direction to form a vortex and to be guided to the baffle plate 30 at the same time. In this role, it is hermetically coupled to the top of the baffle plate (30).

The drain pipe 50 is installed at the lower end of the drain gang 10c described above, and the drain pipe 50 is dropped from the contaminants introduced into the drain gang 10c from the baffle plate 30 or from the air through the drain gang ( 10c) serves to discharge the rainwater introduced to the outside.

5 shows an operation of the stack contaminant removal device 1 according to the present invention, in detail with reference to Figures 1 to 5 the entire operation of the stack contaminant removal device 1 according to the present invention in detail. Explain:

Exhaust gas discharged from various industrial environmental facilities (not shown) is finally discharged through the stack 3, and at the end of the stack 3, a stack pollutant removing apparatus 1 according to the present invention is installed. In this case, the exhaust gas passing through the stack 3 flows through the small diameter portion 10a of the main body 10 and the cylindrical baffle plate 30 to be hermetically coupled to the upper end of the cylindrical baffle plate 30. ).

The exhaust gas forms a vortex as its direction is changed from the vertical direction to the horizontal direction by the collision with the upper plate 40, and the exhaust gas thus diverted is guided to the cylindrical baffle plate 30.

While the doubling gas flows through the cylindrical baffle plate 30, a plurality of corrugated baffle bodies 31 are stacked on each other, and a baffle plate in which wing plates 33 alternately project on both sides of each baffle body 31 ( The flow changes zigzag due to the shape of 30 and contaminants contained in the exhaust gas are collected and separated while flowing through the baffle plate 30 by the principle of inertial impaction.

The air completely purified while flowing through the baffle plate 30 may be discharged to the outside through a space between the baffle plate 30 and the large diameter portion 10b of the main body 10.

In addition, the pollutants collected while the doubling gas flows through the baffle plate 30 are dropped to the lower part of the baffle plate 30 by its own weight, and the pollutants thus dropped may pass through the through hole 21 of the lower plate 20. Passes through and flows into the drain gang 10c and is eventually discharged to the outside through the drain pipe 50.

In addition, the rain water (including the eyes) falling from the air flows into the lower portion through the space between the baffle plate 30 and the large diameter portion 10b of the main body 10, and the rain water thus fallen also penetrates the through plate of the lower plate 20. It passes through the 21 and flows into the drain gang 10c, and is discharged | emitted to the outside through the drain pipe 50 eventually.

As described above, according to the stack contaminant removing apparatus according to the present invention, by combining the end of the stack and the contaminant that is not removed in the industrial environment equipment again to collect the contaminants generated in the process, the effect can be completely removed There is.

In addition, the flow of air is converted to zigzag by the baffle plate, and contaminants can be effectively collected by Chevron's inertia collision principle, and re-spreading of contaminants can be prevented to improve product quality. In addition to this, there is an effect to prevent contamination of the site where the industrial environmental equipment is installed.

In addition, even if the flow rate is installed in a very fast stack, the removal efficiency of the contaminants is not only high, but the pressure loss is not large, which does not interfere with the overall exhaust flow, and can be easily installed at a relatively low cost.
