Description

Apparatus for capturing the powder coke in the cooling chamber of the coke dryer quenching}

The present invention relates to a device that separates and collects the powdered coke contained in the coke when the coke is discharged from the dry fire extinguishing device of the coke oven, and more particularly, the fire extinguishing is maintained in the cooling tower of the dry fire extinguishing facility for a predetermined time. The present invention relates to a pulverized coke collecting device for a cooling tower of a dry fire extinguishing system that collects pulverized coke contained in the bulky coke when the completed cooling coke is discharged through an outlet.

Generally, red coke produced in a COKE OVEN is digested before being charged to the blast furnace. In addition, such a fire extinguishing treatment method of the red coke is a wet fire extinguishing method of extinguishing by water in the digestion tower and the red coke is loaded into the bucket and then lifted up to the cooling tower with the charging crane to charge the coke in the cooling tower, for example, nitrogen: 75%, there is a dry fire extinguishing system which is extinguished by other circulating gas.

Recently, the latter method has been widely used.

Since the dry fire extinguishing method adopts a cooling fire extinguishing method by nitrogen, it is a situation that a lot of dust is discharged due to the relatively low moisture content compared to the wet fire extinguishing method. For example, the moisture content is 4% in wet and 0% in dry. In addition, since the coke has a large amount of dust coke and dust is attached to the coke, in the process of transporting the coke by the conveying belt, a large amount of dust is separated, causing serious environmental problems.

However, since a device for collecting dust or the like is not provided at the outlet of the lower portion of the cooling tower of the dry fire extinguishing method, a large amount of dust is scattered in the process of dropping and transporting the coke from the outlet to the transfer belt.

In general, the pressure inside the cooling tower is set lower than the pressure outside the coke outlet to prevent harmful gas such as carbon monoxide (CO) from leaking into the atmosphere, thereby ensuring worker safety. Residual gas (CO) is leaked to the outlet 3 of the lower cooling tower there is a problem that the risk of safety accidents.

The present invention was devised to solve the conventional problems as described above, the cooling tower of the lower portion of the cooling tower so as to minimize the dust generated in the process of transporting the coke cooled in the cooling tower to the conveying belt through the outlet of the lower cooling tower It is an object to provide a powdered coke collecting device mounted at an outlet.

The dust collecting device 20 is fixed to the lower end of the outlet of the cooling tower, the upper portion is narrower than the center and the lower portion has a narrower jar shape than the inside, the vibration discharger 10 inside the dust collecting at a predetermined position at a predetermined distance It is engaged with the central axis 14 on the shaft support 14-1 fixed on a line extending parallel to the left and right bodies of the device.

In addition, the vibration ejector 10 is a structure having a predetermined slope that can be moved up and down from the center axis 14 as a starting point.

In addition, the lower surface of the vibration ejector 10 is provided with a plurality of discharge holes vertically spaced apart from each other at a predetermined interval, for example, to allow a coke fall of about 3 mm or less, and parallel to the rear end side from the front end of the vibration ejector 10. The triangular guide member 12 which consists of several pieces is provided.

The bearing housing 26 is fixed to one side of the dust collecting device main body for the vertical flow of the vibration discharger at the lower end of the vibration discharger 10, and the bearing housing 29 is fixed to the main body of the same structure on the other side. The camshaft 27 of the snail shape is inserted into the shaft 25 and fixed by the key pin 28 between the bearing housings 26 and 29, and the shaft protrusion part at one end of the shaft 25 to prevent one side of the shaft from tipping. (24), the coupling (22, 23) is coupled to the adjacent shaft projection (24), the coupling and the vibration motor 21 is coupled.

The link fixing part 30 is provided on the lower face of the front end of the vibration ejector 10, and the link part 31 of the filter fixing part 32 is coupled by the link pins 31a and 31b. The upper filter 38 is fixed to the left and right by a plurality of fixing bolts 51a on the fixing unit 32 main body.

In addition, the filter fixing part 32 is provided with a link hole 34 at the bottom of the main body, and a link part 35 which can be fixed to the upper end 30 of the dust collecting device 20 main body, and the face plate 36 front. The side has a straight line, and the rear surface of the nipper is equipped with an air outlet 37 integrated into a funnel shape. In addition, the guide plate 46 having a gentle inclination in the lower part of the dust collecting device 20 and the upper side of the dust collecting device 20 at a predetermined interval so as not to come into contact with the vibration ejector 10. 47) is fixed and a pressure sensor is provided in the dust collecting device.

The lower body of the collecting device is provided with level sensors (41, 42) and dust discharge motor (5).

In the dust collecting device configured as described above, the vibration discharger 10 flows up and down during discharge of the coke falling from the cooling tower discharge port, and the dust coke of 3 mm or less falls below the vibration discharger and is partially around the guide plate and the thrust plate. It will accumulate.

At this time, the air (air) of a certain pressure is introduced to guide the wind direction from the bottom to the cooling tower side under the influence of the guide plate and the upper guide member so that harmful gas does not flow out to the lower side of the discharge port side and continuously around the guide plate and the milge board Air is introduced into the dust to prevent the accumulation of dust and coke.

(RPM) is increased (up to 1150 RPM), and if the present emission value is lower than the discharge setting value, the dry dust collector blower can be signaled to reduce the rotation speed (minimum: 860 RPM) so that the dust in the dust collecting device can be flexibly transferred. Work is done.

Therefore, according to the present invention, it is possible to minimize the dust generated in the process of transferring the coke cooled in the cooling tower to the conveying belt through the outlet of the lower cooling tower, and also according to the dust concentration and gas pollution generated during the vibration process It can improve the production efficiency with comfortable operating conditions, prevent environmental pollution, and prevent safety accidents caused by gas.
