Abstract

PURPOSE:To supply waste tires while collecting a gas generated during the supply without releasing it into the air, by rolling waste tires to supply into a carbonization chamber through a coke push-out opening or waste water outlet while operating an ammoniacal liquor ejector. CONSTITUTION:An oven lid 2 is attached to a carbonization chamber 1, and a guide 11 of a charging device 8 of a pusher 7 is placed into a position close to a coke push-out opening 13. While an ammoniacal liquor ejector 6 is operated, a waste tire 12 in doughnut-like form is rolled on a slope 10 to be supplied into the carbonization chamber 1. The tire 12 rolls on a carbonization chamber floor 9 and hits against the oven lid 2 to stop. In the same manner, tires 12 are kept supplied in order into the carbonization chamber 11 until there is no more space for rolling tires 12 in the chamber. Then the supply is stopped, and an oven lid is attached to the coke push-out opening 13. A lid 14 of a coal supply hole 16 is removed to supply coal through the hole 16 for carbonization of a group 15 of waste tires together with the coal. Since the ejector 16 is operated, the gas generated during the supply of tires 12 and generated from a group of tires is sucked into a riser 3 and collected in a gas collector tube 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for charging waste tires into a coke oven.

[Prior Art] The present applicant previously disclosed in Japanese Patent Application No. 62-152040 that a donut-shaped waste tire is charged into the charcoal chamber of a coke oven through a coke extrusion port or a discharge port, and A furnace lid is attached to the inlet, and then coal is charged into the carbonization chamber through the furnace top coal charging hole, and the waste tires are carbonized together with the coal, thereby recovering and using it as fuel gas without manipulating the coke production amount. A method of operating a coke oven that can increase the amount of coke oven gas generated at a low cost has been provided.

In order to charge the above waste tires into the carbonization chamber, the red-hot coke in the carbonization chamber is extruded using an extruder. A donut-shaped rolling guide for waste tires is installed between the working floor of the extruder, and the waste tires are placed on the rolling guide from the extruder working floor and carbonized by rolling on the slope of the rolling guide. In order to increase the amount of gas generated in a coke oven, waste tires are placed repeatedly on a rolling guide, and as many waste tires as possible are loaded into the carbonization chamber. It is to be charged.

The waste tire that has entered the carbonization chamber through the rolling guide further rolls on the bottom surface of the carbonization chamber and comes to a stop when it hits the furnace lid on the side of the guide car or the already charged waste tire in the carbonization chamber.

Furthermore, the maximum number of waste tires that can be charged into the carbonization chamber using the above charging method varies depending on the size of the carbonization chamber and the size of the waste tires, but for example, the furnace width is 410 mm, the furnace length is 13200 +++
m, furnace height 4300 mm, outer diameter 550++ o.
If about n waste tires are charged, the amount will be about 22 tires.

[Problems to be Solved by the Invention] The temperature inside the carbonization chamber is approximately 1000°C, and by repeatedly rolling and charging doughnut-shaped waste tires from the coke extrusion port, a large number of waste tires are collected. In the process from when charging is completed to when the furnace cover is attached to the coke extrusion port, gas is generated from the waste tires that are rolling in the coke chamber, and gas is also generated from the waste tires that have already stopped being charged into the coke chamber. There was a problem in that the coke was radiated out of the furnace from the upper part of the coke extrusion port, causing air pollution.

The present invention provides a method for charging waste tires into a coke oven carbonization chamber, which prevents the gas generated during the process of charging the waste tires into the carbonization chamber from being released into the atmosphere from the waste tire charging port, and allows the gas to be recovered. It is something to do.

[Means for Solving the Problems] The method for charging waste tires into a coke oven of the present invention includes a bent pipe section that is arranged at the top of the coke oven and connects a riser pipe and an air collecting pipe that communicate with a carbonization chamber. The invention is characterized in that a donut-shaped waste tire is rolled and charged into the carbonization chamber from a coke extrusion port or a discharge port while operating an ammonium water ejector provided in the coke chamber.

[Embodiments and Effects] The present invention will be described in detail below based on the embodiment shown in FIG.

In FIG. 1, 1 is a carbonization chamber, 2 is a furnace lid on the coke guide car side, 3 is a riser pipe that communicates with the carbonization chamber 1 placed at the top of the furnace, 4 is a curved pipe section connected to the riser pipe 3, 5 is an air collecting pipe connected to the bent pipe section 4, and 6 is an ammonium water ejector provided in the bent pipe section 4. 7 is an extruder, and 8 is a waste tire charging device installed on the working floor of the extruder 7. An inclined slope 1o is formed on this slope 10 to prevent the waste tire 12 from overturning and also to prevent the waste tire 12 from overturning.
A pair of guides 11 that regulate the rolling direction of 2 in the furnace length direction.
will be established.

Note that the guide 11 is extended to a flat work floor above the slope 10, and is used to store waste tires 12.

The charging of waste tires using the charging device 8 is as follows.
It is to be implemented.

■ The red-hot coke (not shown) in the carbonization chamber 1 is transferred to the extruder 7.
and discharged through a guide wheel (not shown) into a fire extinguisher or a coke packet (not shown).

(2) Attach the furnace M2 on the side of the guide wheel to the carbonization chamber 1, and align the guide 11 of the charging device 8 of the extruder 7 with the coke extrusion port 13.

(2) Place the waste tires 12 stocked on the work floor on the slope 10, roll them on the slope 10, and operate the ammonium water ejector 6.

The waste tire 12 is rolled on the slope 10 to the carbonization chamber 1.
It enters the inside, further rolls on the bottom surface 9 of the carbonization chamber, and stops when it hits the furnace M2. Further, while operating the ammonium water ejector 6, the waste tires 12 stocked on the work floor are placed on the slope 10 intermittently in order, so that each waste tire 12 rolls on the slope 10, and the carbonization chamber 1 Go inside,
Furthermore, it rolls on the bottom of the chamber 1, and the waste tire 1 in the carbonization chamber 1 is
It hits 2 and stops.

When there is no more rolling space for the waste tires 12 in the carbonization chamber 1, the supply of the waste tires 12 onto the slope IO is stopped.

■ Attach the furnace lid to the waste tire loading port 13.

(2) Using a coal loading car (not shown), take the coal loading M14 and charge an amount of coal commensurate with the amount of coke produced into the carbonization chamber 1 through the coal loading hole 16.

In the charging process of the waste tires 12 described in (3) above, as shown in FIG. Gas is generated from the waste tire group 15 that is being used. However, in the method of the present invention, the ammonium water ejector 6 is operated at the same time as the start of charging the waste tires, and while the ammonium water ejector 6 is operating, the waste tires 12 are fed into the carbonization chamber 1. Since rolling charging continues, the gas is sucked into the riser pipe 3 as shown in FIG.

[Effects of the Invention] As detailed above, according to the present invention, gas generated during the charging process of donut-shaped waste tires into the carbonization chamber is prevented from being released into the atmosphere from the waste tire charging port, and the gas is can be recovered and can prevent air pollution.
