る。2. Description of the Related Art Generally, a coke dry fire extinguishing system (hereinafter referred to as CDQ) as shown in FIG. 3 is known as a system for extinguishing red hot coke extruded from a carbonization chamber of a coke oven furnace. That is, the red-hot coke 2 charged in the cooling tower 1 is cooled by an inert gas 4 blown from below through a blower 5, and the extinguished coke 3 is discharged from the lower part of the cooling tower 1 to the outside of the tower. Things. At this time, the injected inert gas 4 exchanges heat with the red hot coke 2 to increase the temperature, and the high temperature discharged inert gas (normally around 800 ° C.) 3
It becomes 0 and is discharged from the upper part of the cooling tower 1. The high-temperature discharged inert gas 30 is then subjected to removal of coarse dust by a simple settling chamber type dust remover 6, and its sensible heat is recovered as steam in a waste heat recovery boiler 8 (hereinafter referred to as a boiler). Next, the low-temperature discharge inert gas (usually around 200 ° C.) 31 whose temperature has been lowered by heat exchange with the boiler 8 is guided to a dust remover (generally using a cyclone) 10 to remove fine-grained dust, and again to the cooling tower 1. Circulated as inert gas to

2の回収時には、ガス中のかかる微細粒ダストを除塵す
る必要があった。In the cooling tower, hydrogen (H 2 ) gas and carbon monoxide gas (CO) are generated when extinguishing red hot coke. Since the high-temperature discharged inert gas 30 containing a combustible gas such as H 2 or CO has a risk of explosion, immediately after being discharged from the cooling tower, the inert gas 30 is supplied to the dilution air blower 27 in accordance with a change in the gas composition. Air is blown through the connected air pipe 28 to be diluted. For this reason, the amount of gas returning to the cooling tower is sequentially increased. Conventionally, the increased amount is burned as excess gas 32 at the tip of the diffusion tube 11 and emitted into the atmosphere. However, since the emission of the surplus gas 32 to the atmosphere causes a loss of energy, it has recently been recovered as a combustible gas and used as a fuel gas. This surplus gas 32
At the time of recovery / utilization of the gas, since the low-temperature discharge inert gas 31 that has passed through the cyclone 10 still contains considerable fine-grain dust, the dust is contained in a recovery path (not shown) of the surplus gas 32 described later. Has been deposited, causing a problem in the recovery operation. Therefore, the surplus gas 3
At the time of recovery of 2, it was necessary to remove such fine-grain dust in the gas.

A surplus gas recovery method for CDQ was proposed. As shown in FIG. 2, a part of the circulating gas is sucked from a CDQ circulating gas pipe (not shown) as excess gas 32 by a suction blower 21 and guided to the bag / filter 13 to contain fine particles. After removing the particulate dust, the excess gas recovery pipe 14
Is collected in the gas main pipe 15 through the main body. That is,
The excess gas 32 sucked into the bag / filter 13 is condensed and drained due to a decrease in the temperature of the gas, and the drain mixes with and binds to the dust to block the pipe, thereby making it impossible to recover the gas. The problem is that the steam trace 22 is provided on the gas pipe 12 and the main body of the bag filter 13 to suppress the temperature drop by heating the sucked excess gas 32, prevent the drainage, and prevent the bag filter 13.
The heater 19 is also provided for the dust removing gas 33 to heat it.

When the temperature of the pipe 16 is lowered, the vapor in the gas is condensed and drained, and another problem is that the deposits and deposits formed by mixing the drain and the fine particle dust 25 block the discharge system. Occurred. In addition, the condensed water contains sulfur dioxide (S) contained in the gas.
Sulfuric acid was generated by combining with O 2 ), which corroded the inside of the discharge system piping of the dust 25, the discharge blower 17, or the surface of other equipment, and showed an effect of promoting clogging. Further, when the corrosion progresses, there is a possibility that the life of the entire dust removing facility for the surplus gas 32 may be shortened. In addition, 5-548
The equipment described in Japanese Patent No. 79 has disadvantages such as large scale and high construction cost, large consumption of heating steam, and large power consumption in each of a large number of blowers. was there.

Is connected. In other words, bags
The fine dust 25 collected by the filter 13 is continuously extracted from the discharge means 23, dropped into the existing pipe 9 connecting the boiler 8 and the cyclone 10, and collected by the existing cyclone 10. It is. At this time, a part of the surplus gas 32 flows from the bag filter 13 together with the fine dust 25 to the cyclone 10 through the discharge means 23. Of course, as apparent from FIG. 1, the low-temperature discharge inert gas 31 from the existing boiler 8 is used.
However, there is a risk that the discharge means 23 flows backward. In order to prevent the backflow, the CDQ according to the present invention uses the blower 5
Thus, the operation is performed by appropriately operating the gas flow rate adjusting valve 29 disposed in each place. As described above, a part of the surplus gas 32 is caused to flow to the circulation path,
Thus, the amount of gas guided to the surplus gas 32 flow path can be increased. Increasing the gas will increase its heat capacity, resulting in a slower drop in gas temperature. In the present invention, the increase is carried out by increasing the dilution air.

However, the present invention is not limited to this, and any means such as gas conveyance can be used as long as continuous discharging is possible. The CDQ according to the present invention was operated under conditions such that the amount of surplus gas recovered was 4000 Nm 3 / hour. At that time, the amount of gas passing through the bag / filter 13 was increased by about 20 vol% as compared with the conventional case. As a result, the temperature of the passing gas at the inlet of the bag filter 13 was still maintained at about 190 ° C. Further, the gas temperature at the outlet of the spiral conveyor 23 was about 140 ° C., and any troubles associated with the conventional drainage were eliminated.
