Description

Detailed Description of the Invention For example, in a coke dry cooling facility (CDQ), red-hot coke pushed out of a coke oven is put into a bucket, transported to the top of a cooling tower by a transport mechanism, and the bottom of the bucket is opened to remove red-hot coke. Coke is charged into the cooling tower via a charging hopper.

However, when the bucket is removed from the coke oven, it is not done from directly above, so uneven distribution of particle size already occurs in the bucket, and if this condition is brought into the cooling tower, it will also become uneven inside the cooling tower. Uneven distribution of particle size distribution occurs, causing non-uniform flow of gas and coke, which causes a large temperature difference between various parts within the cooling tower. In addition, the coke in the bucket is deposited once in the charging hopper and is then charged by falling from the charging hole, but at the end or early stage of charging, a space is created in the hopper, making it easier for the coke to flow. This increases the charging speed to the cooling tower.
This causes the pressure inside the cooling tower to fluctuate and causes the cooling tower to emit harmful gases containing coke breeze into the atmosphere.

The present invention was made with the aim of solving these causes, and is used in dry cooling equipment for raw materials in which raw materials charged from a bucket are charged into a cooling tower from a charging hopper and cooled. This invention relates to a device for charging coke and other raw materials into a dry cooling facility, characterized in that a movable damper is provided in a raw material passage section in a hopper.

Embodiments of the present invention will be described below with reference to the drawings.

In the charging hopper 2 installed at the top of the cooling tower 1,
A rectangular or elliptical charging hole 3 is opened at the bottom, and a damper (bumpful) 4 is installed in the center of the charging hole 3 to adjust the charging distribution and amount of charging material to the cooling tower 1. is rotatably and tiltably mounted so that it can be moved by a damper drive device 5.

Now, when charging raw materials into the cooling tower 1, the damper 4 attached to the charging hole 3 of the charging hopper 2
is appropriately displaced and tilted. If the raw material is separated into coarse particles and fine particles in the bucket into which the raw material is charged (charged) into the charging hopper 2, and uneven distribution of particle size occurs, as shown in Figs. 2 and 3. The damper 4 is adjusted to change (adjust) the charging distribution of raw materials to the cooling tower 1. As a result, even if the particle size distribution is unevenly distributed in the bucket, this condition will not be brought into the cooling tower 1 as it is, and the particle size distribution at the point where it falls into the storage chamber in the cooling tower 1 will be corrected (adjusted). ), the temperature distribution in the cooling chamber in the cooling tower 1 can be improved, the temperature difference between each part can be reduced, and the raw material can be cooled uniformly.

The above-mentioned damper 4 can be operated by changing the charging position at the beginning and end of each charging time, or periodically, for example, once a day or a week. By adjusting the amount of raw material charged per unit, it is possible to adjust the charging speed to the cooling tower 1 at the beginning and end of charging as described above, and it is possible to prevent the pressure inside the cooling tower 1 from fluctuating. Emission of harmful gases into the atmosphere can be avoided.

As described above, according to the present invention, the purpose is to solve the cause of temperature non-uniformity that occurs when the uneven distribution of particle size distribution generated in the bucket is brought into the cooling tower,
The purpose of solving the cause of the release of harmful gases that occurs due to the increase in charging speed at the end and the beginning of material charging into the cooling tower is to move the movable damper by rotating and tilting it in the left and right directions. This can be achieved by changing (adjusting) the charging distribution by displacing the movable damper and adjusting the charging amount per unit time by varying the amount of material on the damper by tilting the movable damper. It is possible to correct the uneven distribution of particle size distribution in the cooling tower, which is caused by the occurrence of particle size distribution in It can have the excellent effect of avoiding release.
