Abstract

PURPOSE:To provide a packed bed type washing and dust collecting apparatus having a structure capable of washing packing without stopping the apparatus. CONSTITUTION:A packed bed rotating shaft 7 is provided to a packing receiver 8 having packing received therein and directly connected to the rotary motor provided to the outside of a packed tower. By this constitution, since the dust or reaction product bonded to the packing can be washed off without shutdown of the packed tower, operation can be performed under always stable pressure loss.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning and collecting exhaust gas containing harmful gas or dust, and more particularly to a packed bed type packed tower.

[0002]

2. Description of the Related Art A conventional packing tower, as shown in FIG.
Intake port 1, exhaust port 2, wash water supply port 3, wash water drain port 4, demister 5, filler receiver 8 containing filler
Has a filling layer 6 composed of Next, the operation will be described. Exhaust gas containing harmful gas or dust is sent to the packing tower from the intake port 1, the cleaning liquid supplied from the cleaning water supply port 3 becomes a spray, flows downward, and water is applied to the surface of the packing material installed in the packing layer 6. Cleaning and dust collection processing is performed by forming a film, inertial collision with exhaust gas sent directly, or diffusion and adhesion of fine particles. In the demister 5, water is removed and the purified gas is exhausted through the exhaust port 2
Had been discharged more. In addition, the cleaning water is the cleaning water drain port 4
It was constantly drained and the amount of liquid in the packing tower was adjusted to be constant.

[0003]

In this conventional packing tower, dust and reaction products may adhere to the packing, resulting in increased pressure loss and difficulty in operation. , Remove the packing from the device, wash,
It was necessary to fill the packing tower again. For this reason, a lot of manpower and time are required, and it is impossible to stop the device frequently in a 24-hour full operation, so that the pressure loss must be high. There was a point.

The object of the present invention is to make it possible to regularly wash off dust or reaction products adhering to the packing material without stopping the apparatus, and to always provide a stable pressure loss without requiring manpower or time. It is an object of the present invention to provide a packed bed type cleaning and dust collecting apparatus capable of operating the packed bed type cleaning and dust collecting apparatus under the circumstances.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a packed bed rotating shaft 7 integrated with a packing receiver 8 for rotating a packed bed 6 for cleaning the packing of a packed tower without stopping the apparatus. Is equipped with.

[0006]

The present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a packed column according to an embodiment of the present invention. The filling layer 6 is in a state in which the filling is stored in the filling receiver 8. In view of this, in this embodiment, the packed bed rotary shaft 7 is provided in the center of the packing receiver 8 and a rotary motor is installed outside the packed tower, and the packed bed rotary shaft 7 is directly connected to the packed bed rotary shaft 7 to periodically fill the packed bed 6 in half. It is to rotate.
The dust and reaction products collected in the packing grow and collect in one direction where the packing is present because the gas flow and the cleaning liquid flow are always constant. In this embodiment, the dust and the reaction product are periodically washed by rotating the filling layer half way to wash away the dust and the reaction product from the reverse of the growth direction using the washing liquid.

[0007]

Industrial Applicability As described above, according to the present invention, it is possible to regularly wash off dust or reaction products adhering to the packing material without stopping the apparatus, and always without manpower or time. This has the effect that the packed bed cleaning and dust collecting apparatus can be operated under a stable pressure loss.
