DEVICE FOR COLLECT DUST AND DISCHARGING OF FUME DUCT DUST IN EMISSION CONTROL SYSTEM}

The present invention relates to a fume duct dust collection and automatic discharge device of the dust collector to collect the dust of the fume duct (FUME DUCT) installed in the dry dust collector system of the coke plant to automatically discharge it, in particular, coke oven Through the fume duct, which is an accessory of the dry dust collector system installed in the operation, the dust collected with large particle size during the extruding of the red coke, and the life and performance degradation materials of the dust collector such as relatively heavy particles and rain water generated in rainy weather The present invention relates to a fume duct dust collection and automatic discharge device of a dust collector, which is equipped with an automatic processing device for separating and preliminary collecting by car to prevent the occurrence of trouble of the coke dust collector and to prevent the occurrence of environmental pollution by maximizing its performance. .

In a commonly known steelworks coke plant oven, a dust collection system for collecting dust gases generated during the extraction and production of coke products is divided into two processes according to the composition of the coke oven, classified and extracted with a dry dust collector. It has the characteristic of running only at work.

1 is a schematic configuration diagram showing a process of a general coke oven dust collector, wherein the dust gas dust collecting system 10 is a coke feeder 11 used in the production operation of the red coke 9 in a carbonization chamber of the coke oven 8. The fume duct 13 which is a transport pipe which collects the dust 19 generated from the hood 12 of is installed.

The fume duct 13 is composed of a circular pipe having a ┬ shape of 1M or more in diameter so that the inlet pipe 13-1 is incised on the upper side, and the belt 14 is covered on the incision. When the belt lifting device 15 of the coke feeder 11 is transported to the working position, the dust is fed through the lower cut-out space 16 of the portion where the belt 14 is lifted, and the fume fuse of the coke feeder 11 is removed. Collection work is performed through the inlet pipe 13-1 cut in (12), and the circular "I" type main dust collector transport pipe 13.

At this time, when the main fan 18 of the dust collecting system 10 is operated, suction pressure is collected in the BAG chamber 17 of the dust collecting facility 10 through the dust collector transfer transport pipes 12, 13-1, 13, The dust 19 collected in the BAG chamber 17 is separated into dust and clean air through a dedusting (exfoliating) operation, and the separated dust 19 is accumulated in an appropriate amount in the BAG chamber hopper 17, and thus, secondary The dust is collected in the dust silo 22 through the transfer line 21 by operating the dust collecting blower fan 20 for the purpose of exhausting the dust. The collected dust is collected in the collecting box 23 to collect the treatment vehicle 24. It is discharged through.

On the other hand, in the conventional dust collection system as shown in Figure 2 during the dust treatment process as described above, the use of the line is reduced by the pinhole 25 that the line thickness becomes thin in the course of the transfer through the dust transfer line 21. As a result, the dust is poorly collected, as well as equipment troubles in proportion to the amount of dust generated, causing frequent equipment downtime. In summer, the first inlet-side transfer pipe 13-1 is cut and the belt 14 is disposed thereon. When a large amount of rain water is generated, it is sucked by the dust collector operating suction pipe pressure, and clogging of the eye 26 of the BAG filter in the BAG chamber 17 occurs. And it is impossible to discharge the phenomenon due to the solidification of the dust inside the hopper 17, there is a disadvantage that the operation of the pollution prevention equipment falls.

In the above phenomenon, although the particle size range of the dust 19 collected by the dust collector is small, the particle size of the dust 19 is preferably 10 μm to 0.1 μm or less. When the shape is formed into a polygonal shape like a grain of sand, the collection of the line 21 and the bent portion ⓐ, ⓑ by friction occurs when collected through the line 21, causing a pinhole 25, Particles having a large particle diameter of the red coke dust are accompanied by a high temperature heat source, causing damage and fire to the BAG filter 26, causing problems during operation of the dust collector 10 facility.

The present invention has been made in order to improve the various problems as described above, the object of which is to separate the foreign matter deteriorating the life and performance of the dust collector through the spark baffle plate of the transfer pipe, the collection and discharge hopper and hopper By discharging through the gate, it is possible to prevent dust collector's troubles caused by dust, to prevent downtime of the production equipment, improve the service life of the equipment, and to collect the fume duct dust of the dust collector, which can prevent the occurrence of pollution. And to provide an automatic discharge device.

It consists of the structure installed in the inlet part of the pipe | tube 30.

Referring to the operation and effect of the present invention made of such a configuration as follows.

As shown in Figs. 3 to 5, when the red coke 9 compression operation is started, the dust collector 10 as shown in Fig. 5 is operated, and the red coke dust 19 collected at the same time as the dust collector 10 is operated. Particles having a large particle diameter (1 mm to 12 mm or more) and particles having a relatively high weight are passed through the transport pipes 13 and 13-1 to reach the transport pipe 30, and then separated horizontal two-stage guide plate 31. , 32, and firstly hit the rotary "V" type baffle plate (31-1, 32-1) by the suction pressure to fall to the inlet (47) of the hopper 34, and the rain water in summer The collection hopper 34 is collected along the lower side of the transport pipe.

In addition, water and dust scattered at this time are caused by the resistance to strike and the structure of the "V" type baffle plates 31-1 and 32-1. Phenomenon) and accumulate in the inner groove 54 of the "V" type baffle plate,

The baffle plate (31-1, 32-1) is applied to the end of the guide plate before, after 45 degrees in accordance with the suction force (ⓓ) so that dust is collected according to the dust collector suction pressure situation generated. .

In addition, the dust 19 accumulated in the inner groove 54 by the vortex effect ⓒ of the "V" type baffle plate during the dust collecting operation is initially positioned by the weight of the "V" type baffle plate with the end of the dust collecting operation. While returning to the to be discharged to the hopper 34 naturally by the reverse rotation.

On the other hand, the lower the weight of the dust collected on the horizontal end of the collecting port 47 is a hook-shaped backflow prevention plate to prevent being sucked into the dust collector 10 after the middle (ⓔ) on the collecting port 47 side Dust is hit by the reverse action of (33-1) and falls to the hopper side, and the adjustment operation is made around the upper and lower shafts (33-2) within a range of 45 degrees depending on the suction pressure state of the dust collector (10). In addition, the hopper is configured in a two-stage vial bottle shape, the primary collecting port 47 has a large diameter, so that a large amount of dust is collected, the secondary collecting port 48 is configured to collect a small diameter The dust 19 prevents backflow of dust even when negative pressure is generated due to an abnormal occurrence, and the surface area 49 of the collected dust is made small in a vertical form, depending on the dust collection weight. The discharge pressure becomes high, It is facilitated imhyeong discharged through the outlet 36.

On the other hand, the gate 41 of the frame-type discharge port 36 is naturally opened when the weight of the collected dust is higher than the weight of the weight 43 in the closed state by the lever lever to the bar center axis 45. It is made, if less than the weight of the weight is closed, to adjust the weight of the weight to control the discharge of the dust, the circular plate 41 is attached to a good sealing rubber plate (41-1) Close contact with the frame outlet is free.
