Description

Smoke treatment equipment {smoke treatment equipnent}

The present invention is to rotate the rotating disk formed with the spokes at high speed while spraying water at a high speed radially using the centrifugal force of the rotating disk to a small amount of various contaminants introduced into the vacuum layer generated by the rotation of the rotating disk It relates to a soot treatment device that can be effectively removed even with water or chemicals.

Conventional soot (soot generated from various incinerators, combustion kilns, etc.) treatment apparatus mainly passes the soot into the water film or installs a spray nozzle in the soot exhaust pipe to spray the water when the soot is discharged to cool the soot. After the pollutants contained in the water were washed down, the water was purified to remove the pollutants contained in the continuous stream. However, the above methods have a large amount of toxic pollutants because the removal performance of the pollutants is poor. In the case of this soot, not only does the pollutant not be completely processed, but the amount of water used is very high and various pollutants are washed, and the contained water needs to be purified again. Because of the high cost of facilities and the large scale of facilities, they require a large installation area. There were many problems with the space constraints.

The present invention has been made in order to solve the above-mentioned conventional problems to rotate the rotating disk with the spokes formed around the high speed to form a vacuum layer for sucking the contaminants of continuous smoke around the spokes and at the center of the rotating disk The sprayed water or chemicals can be sprayed radially by using the centrifugal force of the rotating disk to maximize the contact area with the pollutants and achieve high-speed contact, effectively removing the pollutants contained in the smoke using a small amount of water or chemicals. It will be described in more detail by the accompanying drawings as follows.

A fume inlet duct 2 is installed in the lower part of the cylindrical body 1, and a fume discharge duct 3 is installed in the upper part of the main body 1 so that the driving motors 4 and 4a are respectively provided at the centers of the upper and lower ducts. After the installations face each other, the rotary disks 5 and 5a in which the spokes 51 and 51a are radially formed on the flanges 41 and 41a provided on the drive shafts of the respective driving motors 4 and 4a are combined. , The odd number of rotation disc 5 in the upper portion to form a connecting portion 52 at the edge to connect a plurality of rotating discs 5 vertically installed in the connection portion 52 a plurality of water outlets 521 penetrated from the inside to the outside The number of rotation discs 5a at an even number in the upper part is installed vertically with a plurality of rotation discs 5a with a fixed shaft 54 with a gap retaining hole 55 between the rotation discs, but the upper drive motor 4 and The lower driving motor 4a is rotated in opposite directions, and through holes 53 and 53a are formed at the center of each of the rotating disks 5 and 5a. The rotating disk 5 has a larger diameter of the through hole 53 than the even rotating disk 5a, so that the fixed shaft 54 fixing the even rotating disk 5a has an odd number of the centers of the rotating disk 5. It is located inside the study (53) and the upper drive motor (4) is formed in the bottom of the sump (7) in communication with the washing water supply pipe (6a) to combine the washing water spray pipe (6) and the motor shaft in the washing water spray pipe The upper part of the (6) forms a plurality of washing water supply hole 62 and the bearing 72 and the airtight hole 71 is installed at the bottom of the sump (7) to maintain the airtight and wash water spray pipe (6) can be rotated In the washing water spray pipe (6) exposed to the outside of the sump (7) to form a plurality of spray holes (61) to be installed vertically downward in the center of the rotary disk (5) (5a) and the main body ( 1) It is a structure formed by forming a washing water discharge pipe (7) at the bottom.

According to the present invention, the driving motor 4 installed on the upper and lower portions of the main body 1 while injecting the soot generated from the incinerator, the combustion kiln, or the welding gas through the soot inlet duct 2 installed below the main body 1 is provided. When the rotational direction of (4a) is reversed and operated, the number of rotation disks 5 from above is rotated counterclockwise by the upper drive motor 4, and the number of rotation disks 5a is lower drive motor ( It rotates clockwise by 4a).

When the rotary disks 5 and 5a are rotated at high speed by the driving motors 4 and 4a, the fumes introduced through the fume inlet duct 2 under the main body 1 rotate by the rotational force of the rotary disk. It rotates along the disks 5 and 5a. Since the rotating disks 5 and 5a have spokes 51 and 51a having a cross-sectional shape of "<" or ">", they are radially rotated. When the original plates 5 and 5a rotate at high speed, as shown in FIG. 5, a vacuum layer is formed at the portions where the spokes are formed at the rear of the spokes 51 and 51a in the advancing direction, and the fine layers contained in the vacuum layer are continuously contained. Contaminants are sucked in.

At this time, when spraying the washing water or chemicals in the spray hole 61 of the washing water spray pipe (6) formed perpendicular to the lower part of the upper drive motor (4) sprayed washing water or chemicals to the surface of the rotating disc (5) (5a) However, due to the centrifugal force generated when the rotating disc 5 (5a) rotates at high speed, washing water or chemicals on the surface of the rotating disc will be diffused to the outside of the rotating disc 5 (5a). While washing water or a chemical is sprayed into the vacuum layer behind the spokes 51 and 51a radially formed around the rotary disks 5 and 5a, various contaminants of the soot sucked into the vacuum layer are contacted at high speed.

Thus, the contaminants introduced into the vacuum layer are collected by washing water or chemicals and then discharged to the outside through the discharge pipe installed in the lower part of the main body 1 by flowing down on the inner wall surface of the main body 1. In the case of the rotating disc 5 formed therein, the washing water or the chemical is discharged to the outside of the rotating disc 5 through the water outlet 521 formed in the connecting portion 52, and then flows to the inner wall surface of the main body 1. Get off.

On the other hand, washing water or chemicals are sprayed by spray disks 5 and 5a which are rotated at high speed in the spraying state at the initial stage, and the main body is driven by driving motors 4 and 4a respectively installed above and below the main body 1. (1) Dividing the rotary disk (5) (5a) installed inside into odd and even numbers and rotating them in opposite directions, so that spraying can be maintained continuously during the spraying of washing water or chemicals. By maximizing the contact area with the material, the contaminant can be removed very effectively.

In addition, in the present invention, the rotary disk (5) (5a) is used to install two types of vertical at regular intervals, wherein the number of the rotary disk is not limited to a specific number, but the number of the rotary disk (5) (5a) It is noted that the higher the number, the better the performance of treating contaminants.

Therefore, the present invention maximizes the area of contact with soot by atomizing finely sprayed washing water or chemicals using a rotating disc made of a disc shape, maximizing the treatment efficiency of pollutants and minimizing the amount of washing water or chemicals used to operate the smoke treatment apparatus. In addition to minimizing the required cost, the device can be miniaturized to increase space utilization.
