That is, the slag is usually intermittently performed every hour, and a large amount of dust and smoke is generated from the slag outlet 30 as a jet gas with the slag. In connection with the slag opening device 36, it cannot be closed with a dust cover or the like, and is sucked by the hood 33 provided above the slag outlet 30 as described above.

As shown in FIG. 1, in the present embodiment, during normal operation of the waste melting treatment facility A, the first flow path switching valve 43 is opened, and the second flow path switching valve 44 is closed. . Then, by the operation of the combustion air blower 19, the air in the refuse storage chamber 11 is moved through the combustion air suction pipe 20 → the combustion air blower 19 → the combustion air supply pipe 18 to the combustion furnace 1.
7 will be supplied. Thus, the combustion air blower 19 has a large capacity since a large amount of combustion air must be supplied to the combustion furnace 17, and for example, has a maximum capacity of 5500.
At 0 Nm 3 / h, the air in the refuse storage chamber 11 can be supplied into the combustion furnace 17 as product gas combustion air. Also, by sucking air from the refuse storage chamber 11,
The refuse storage room 11 can be set to a negative pressure, and the refuse storage room 1

The second flow path switching valve 44 is opened. Thereafter, by the operation of the combustion air blower 19, the blast gas including dust and smoke generated with the slag of the molten slag from the slag port 30 is generated.
The air is sucked together with the air in front of the slag outlet 30, and the air blow duct 42 →
The air is supplied into the combustion furnace 17 through the combustion air suction pipe 20 → the combustion air blower 19 → the combustion air supply pipe 18. Since the combustion air blower 19 has a large capacity as described above, therefore, even if a large amount of dust or smoke is generated due to the slag discharge of the molten slag from the slag outlet 30, the blast containing the slag is generated. The gas is, for example, 35,000 to 40,000
If it is Nm 3 / h, it can be completely sucked and can be supplied into the combustion furnace 17 as product gas combustion air.

集塵フード４１内に吸引することができる。As described above, all of the jet gas including a large amount of dust and smoke generated at the slag port 30 can be supplied into the combustion furnace 17, so that the working environment around the slag port 30 can be remarkably improved. . In addition, the effluent gas is transferred to waste melting facility A
Therefore, there is no concern about pollution caused by the gas ejected from the slag port 30. In addition, there is no need for equipment cost for dust removal of the ejected gas. Further, in the present embodiment, as shown in FIG. 2, the suction opening of the dust collecting hood 41 can cover the slag port opening device 36 at the forward position provided in front of the slag port 30. Has an area.
Therefore, a large amount of dust and smoke generated when the slag opening 30 is opened by the slag opening device 36 can be more effectively sucked into the dust collecting hood 41.

Scattered by the blow air from the tip of the bit, and the scattered area is mainly in the vicinity of the slag port 30, but the amount of dust is large. During the slag, there is relatively little smoke. In the last stage of the slag discharge, dust and smoke are ejected along with the combustion flame of the furnace gas in the waste melting furnace 14, but the front is shielded by the heat shield plate on the front of the slag outlet 30. Do not leak. At the time of oxygen cleaning, a large amount of black smoke is generated, and at the end of cleaning, the combustion gas in the furnace is blown to a distant place to move the heat insulating plate in front of the slag port 30.

The configuration was adopted. That is, as shown in FIG.
A plurality of suction chambers 47, 48, and 49 are formed in this order in a direction away from the slag port 30, and each suction chamber 47,

なく、設備費も可及的に抑えることができる。According to the dust collecting method of the waste melting furnace according to the first and third aspects of the present invention, a large amount of dust and smoke emitted from the waste melting furnace at the time of slag discharge is generated. The suction gas is sucked into a dust collecting hood provided above the slag outlet, and the jet gas is supplied into the combustion furnace through an air duct to which a large-capacity combustion air blower is attached.
By using a large-capacity combustion air blower, it is possible to supply all the blast gas containing a large amount of dust and smoke generated at the slag outlet into the combustion furnace, so that the working environment around the slag outlet is significantly improved. Can be. Further, since the ejected gas can be treated in the system of the waste melting treatment facility, there is no concern about pollution and the facility cost can be reduced as much as possible.

えない。According to a second aspect of the present invention, there is provided a method for collecting dust at a slag outlet of a waste melting furnace, wherein a large amount of dust and smoke generated at the slag outlet of the waste melting furnace is discharged at the time of slag discharging. Through a dust collection hood provided above the front of the mouth, through a ventilation duct to which a combustion air blower is attached, air is selectively sucked into the combustion furnace from the refuse storage chamber and supplied to the combustion furnace. I am trying to do it. Therefore, it is possible to collect dust only in the slag work performed for each waste melting treatment in the waste melting treatment equipment, and to suck the air in the normal garbage storage room. Has no effect.
