As shown in FIG. 3, the sweeper 60 is provided with a windmill-type vane, and each end of the vane is equipped with a brush 58 to easily remove dust accumulated on the inner surface of the stack 307. It is configured to do so.                     

For reference, the sweeper 60 is equipped with a windmill-type sweeper 60 in a frame (not shown) coupled to the washing liquid storage tank 42, and a driving roller 44 at the center of the windmill-type sweeper 60. Since it is comprised, it is the structure which can be rotated by washing liquid fall.

The configuration of the washing liquid inlet 43 is, as shown in Figure 4, is provided with a hollow tube 56 that can be supplied with the washing liquid in the center, the top is enlarged so that it can be easily inserted into the washing liquid supply portion It has a mold 52.

The air volume control unit of the present invention will be described with reference to FIG. 3.

The air volume control unit is composed of an air volume plate 46 of an umbrella-shaped rigid plate material that can be unfolded by the discharge air volume formed inside the stack 307. The umbrella-shaped rigid plate material is a structure supported by the some external support body 48 and the internal support body 47, and the air volume plate support 49 is provided in the center.

The upper portion of the air volume plate support 49 is bonded and fixed to the fixing ring (47a) is the end of the outer support bar 48, the inner support bar 47 is bonded to the outer support bar 48 to the fixing ring It is a structure joined and fixed to the movement ring 48a of the lower part 47a.

Referring to Figures 5 and 6 will be described the washing liquid supply unit of the present invention.

As shown in FIG. 6, the washing liquid supply unit includes a washing liquid supply pipe 45 that rises to the upper portion of the stack 307 along the height direction of the outer surface of the stack 307. The upper end of the washing liquid supply pipe 45 is provided with a washing liquid supply device for supplying the washing liquid to the washing liquid storage tank 42 of the cleaning unit mentioned above.

As shown in FIG. 5, the cleaning solution supply device has an opening 56 formed therein so that the cleaning solution inlet 43 of the cleaning unit can be inserted therein, and the opening 56 is provided by the packing device 55. The structure is covered to prevent discharge.

The spring 53 is coupled to the upper portion of the packing device 55, so that when the washing solution inlet 43 is inserted, the packing device 55 is raised so that the washing solution is introduced into the washing solution inlet 43.

Hereinafter, the operation of the present invention will be described with reference to FIGS. 3 to 7.

The operation of the present invention utilizes the airflow phenomenon 41 in which the airflow amount due to the start of the main fan 301 is discharged from the bottom of the stack 307 to the top during dust collection operation of the pollution emission prevention facility.

When the facility main fan 301 for pollution discharge prevention is started during the coke oven extrusion operation, the air volume is formed inside the stack 307 by suction pressure.

When the air flow out of the stack 307, the moving ring 48a of the air volume plate support 49 is operated so that the air volume plate 46 of the dust removing device under the stack 307 is opened, and thus the air volume of the rigid air flows. Plate 46 is flattened.

When the air flow rate plate 46 is opened as described above, the dust removal device rises upward through the wall of the stack 307 by the discharge air flow pressure.

The dust removal device that rises to the top of the stack 307 is fixed by the cross bar 62 of the stack 307. At this time, the air volume plate 46 of the dust removal device is operated while the cross stopper 50 is operated. Folded up.

The pressure of the air volume inside the stack 307 is discharged to the outside between the folded air volume plate 46 and the cleaning liquid storage tank 42 of the cleaning unit (see the top of the stack shown in FIG. 7). The dust removal device of the washing liquid storage tank 42, the washing liquid inlet 43 installed on the upper surface of both sides push the packing device 55 of the washing liquid supply device spring 53 of the washing liquid supply device is raised.

Therefore, the opening 56 is opened due to the spring 53 of the washing liquid supply device being raised, and the washing liquid is introduced into the washing liquid storage tank 42 through the washing liquid inlet 43.

When the washing liquid supply is completed, the dust removal device is lowered to the bottom of the stack 307 due to the weight of the washing liquid stored in the washing liquid storage tank 42, the washing liquid through the washing liquid outlet 57 formed on the lower surface of the washing liquid storage tank 42 It is discharged.

The above-mentioned windmill type sweeper 60 is rotated by the drop of the washing liquid discharged, and dust accumulated on the wall of the stack 307 is removed by a brush 58 coupled to the end of the sweeper 60. do.

For reference, the cleaning liquid used to remove dust is discharged through the outlet 63 at the bottom of the stack 307 after the cleaning operation, and the lowered dust removing device is stopped by the stop bar 61 shown in FIG. 6. And the operation ends.

As described above, according to the present invention, the dust removal device is raised and lowered on the inner surface of the pollution emission prevention equipment stack by the discharge air volume, and thus, dust accumulation accumulated on the inner surface of the stack can be removed to prevent contamination of the surrounding environment and the efficiency of the dust collector. It is expected to reduce the labor burden and the risk of safety accidents, which were imposed during the increase and removal of dust inside the stack.
