Description

Inclined Coke Oven

1 is a cross-sectional view of an inclined furnace type coke oven of the present invention taken along line II of FIG.

FIG. 2 is a cross-sectional view of the heating flue of an inclined furnace type coke oven taken along line II-II of FIG.

3 is a partial cross-sectional view of an inclined furnace type coke oven having a single oven furnace chamber according to line III-III of FIG.

The present invention relates to an inclined furnace chamber type coke oven in which a bottom surface of an oven cokes coal briquette-shaped material configured to be inclined downward from a heating wall toward a coke discharge wall.

German patents 144,579 and 151,136 describe a gasification oven and an oven for making peat coke with a horizontal ceiling and an inclined bottom, respectively.

In the case of the German Patent No. 144,579, the charge must be at a constant height at all positions on the bottom of the furnace chamber to uniformly heat the chamber and recover the gas above the charge. Only part of the furnace was filled, and as a result the furnace volume was not fully available.

In addition, in the oven of German Patent No. 151,136 used for the coking of peat, the peat has the drawback that the coking is different according to the position of the oven furnace.

German Patent Nos. 198,471, 235,038, 378,200, 411,885, 455,450 and 671,997 describe a furnace-type oven inclined to the ceiling and the bottom, so that the height of the furnace in all positions is constant. It is true that in these ovens a vertical heating flue is formed on both walls of the furnace to heat the material in the furnace, so that some degree of coking occurs, but this type of oven is comparable to an oven furnace with horizontal ceiling and inclined floor. When the structure is very complex and small in volume, the charge can only be charged through a single charge.

It is an object of the present invention to provide an inclined furnace type coke oven that can coke uniformly by using the entire space in a furnace room whose height is not uniform and simplify the operation of charging, heating and discharging the oven furnace room. .

This object is achieved by the apparatus of the present invention having a vertical heating flue connected to the heating wall of the furnace chamber by an induction opening, the bottom of the heating flue having a plurality of nozzles mounted parallel to the inclination angle of the bottom of the furnace chamber. have.

Induction openings of each heating year were sequentially formed to descend from the heating wall toward the coke removal wall of the oven to be less than the bottom slope of the furnace chamber.

Air is supplied to the heating flue at different heights through the upper air inlet and the central air inlet, and each air inlet is inclined downward from the heating wall of the oven to the side of the coke removal wall so that it is smaller than the inclination of the bottom of the furnace chamber but inclined more than the inclination of the induction opening. Formed.

According to the present invention, even if the height of the furnace chamber is different, uniform coking can be achieved. Initially, the charge is completely filled to the top of the furnace chamber, but once the coking operation begins, the charge in the higher part decreases more rapidly and decreases faster than the charge in the lower part, so the coke removal side of the furnace compartment is charged. A gas collection space is automatically formed in the water phase and the top surface of the charge is sloped further downward as it descends from the heating wall to the coke removal wall.

The charging capacity of the oven according to the invention is substantially larger than known ovens having a uniform furnace height.

Uniform coking can be improved by forming a bottom air inlet at the bottom of the heating flue. More uniform coking can be achieved by injecting air independently from the air inlets at the center and top of the heated flue.

Each heating year is advantageously connected to a regenerator designed to meet the required heat capacity of the corresponding heating year. Each regenerator capacity depends on the amount of off-gases obtained within each heating year.

According to another aspect of the present invention, each heating flue is connected to the branched gas conduit, and all the gas conduits are separately extended to the heating wall of the oven so that each heating flue can be adjusted separately. That is, the gas conduit can speak horizontally to the heating wall or vertically down the oven.

When the heat accumulator is formed in a vertical bent form having a longitudinal portion and a transverse portion, the space portion under the oven furnace chamber and the heating side wall can be used effectively. In addition, if the heat accumulator is separated and connected to the bottom conduit extended to the heating wall of the oven, space can be used economically and the air discharged from the heating wall of the oven and the injected air can be controlled by a simple device.

By allowing the gas conduit and the air conduit to be separated and controlled from the outside of the oven, the amount of combustion material injected into the heating flue can be controlled.

In another embodiment of the present invention has a plurality of charging holes in the furnace ceiling of the inclined furnace type coke oven, these charging holes are formed in the longitudinal direction of the oven furnace chamber, the charging operation is easy and the contents are uniformly in the room It became distributed.

The charging port located close to the heating wall of the oven is formed to be inclined toward the heating wall of the oven, so that the injected coal is inclined toward the heating wall and is uniformly stacked in the oven rather than falling vertically through the charging port.

When charging, charge first at the charging slot located close to the heating wall of the oven and at the same time at the remaining charging slots or sequentially.

Since the gas outlet for recovering gas from the furnace is located in the area where the height of the furnace is highest, the gas collected in the wedge-shaped gas recovery space, which is widely formed above the contents of the oven toward the coke removal wall, can be recovered simply and completely. have.

The present invention will be described in detail with reference to the accompanying drawings.

According to FIG. 1, the coke oven consists of the oven furnace chamber 1 which consists of the inclined bottom 2 and the horizontal ceiling 3. As shown in FIG. In the coke outlet wall 4 of the oven, an outlet 5 was formed at the bottom of the furnace chamber bottom 2 and the outlet 5 was sealed with a lid (not shown). Five charging holes 6 are formed in the furnace chamber ceiling 3, but the charging holes 6 are narrow at the top and wide at the bottom. The charging hole 6 located close to the heating wall 13 of the oven is inclined toward the heating wall 13 while extending vertically to the furnace chamber bottom 2 so that the charging material can be gradually filled in the room. The gas outlet 7 is formed at the position where the ceiling 3 and the bottom surface 2 of the furnace chamber 1 are farthest apart.

A heat accumulator (8) consisting of a vertical portion (10) and a horizontal portion (11) below the furnace chamber (1) is formed separately from the partition wall (9) so as to communicate with the conduit (12) extending to the heating wall (13). .

The volume of the heat accumulator 8 is such that each heating flue 18 of different height can accept the amount of exhaust gas. The flue 18 was formed in the heating side walls 17 on both sides of the furnace chamber 1 and communicated with the heat accumulator 8. Since a large amount of hot exhaust gas is obtained in a flue rather than a short flue, the volume of the heat accumulator 8 connected to the long heated flue 18 is wider than the volume of the heat accumulator connected to the short hot flue.

According to FIG. 3, there is a main heat storage unit 14 under one oven furnace chamber 1, and two auxiliary heat storage units 15 are installed on both sides thereof, and each heat storage unit 14 and 15 has a partition 16. Separated. 3 is shown for one oven furnace chamber 1, but two or more oven furnace chambers and heat accumulators may be spoken.

2 shows the arrangement of the vertical heating flue 18 mounted on both heating side walls 17 of the oven furnace chamber 1. The heating flue 18 is formed of two sets of flues communicating above the brick partition wall 26, and the bottom 24 of the heating flue 18 is positioned at the same level as the bottom of the furnace chamber 2 of the oven. do. On the bottom surface 24 of each heating flue 18, a nozzle 19 connected to the gas conduit 20 is installed, and the gas conduit 20 has an oven horizontally to the heating wall 13 as shown in FIG. Give a speech. In addition, a bottom air injection hole (not shown) is formed in the bottom surface 24 of the heating flue.

An air conduit 21 is provided in each heating flue 18, and each air conduit 21 has a central air inlet 22 and an upper air inlet 25. The air inlets 22 and 25 of the air conduit 21 are connected to a separate inclined conduit descending from the heating wall 13 of the oven to the coke removal wall 4. The air inlet 22 is positioned below the central portion of the heating flue 18 and the air inlet 25 is positioned at the center of the heating flue 18 so that a line connecting each upper air inlet and the lower air inlet is It is possible to maintain the inclination angle less than the inclination angle of the furnace chamber bottom (2).

In this arrangement, since each of the flues 18 forms a long fire reaching the height of the oven oven chamber 1, the contents in the oven furnace chamber 1 are uniformly heated and coked.

That is, the air inlets directed into each heating flue 18 are located at three different heights so that the injected air is at the bottom air inlet at the bottom face 24 of the heating flue 18 and at the center and upper air inlets 22, 25. Is injected separately. Air is injected from each regenerator to the air inlet of the corresponding heating flue by the same method and apparatus as in a conventional coke oven.

The heating flue 18 was communicated with each other at the top by an induction opening 23 formed on the line inclined downward from the heating wall 13 of the oven to the coke removal wall 4. The line connecting each opening 23 has a smaller inclination angle than the bottom surface of the furnace chamber 2 and a smaller inclination angle than the connection lines of the air inlets 22 and 25. Coal charged in the furnace chamber is reduced more at the height of the furnace chamber so that the induction opening 23 in the longest heating year 18 is lower than the induction opening 23 in the short heating year 18. So that the charge is evenly heated. Therefore, even if the height of the oven furnace chamber 1 is not uniform, a uniform coking effect is achieved by the arrangement of the heating flue 18 and the formation of the flame as described above.

The oven described above may be heated in other ways. For example, in a two-year oven, the secondary gas conduit 20 is connected to the gas pipe and the remaining gas conduit supplies only a small amount of air to combust the deposits of carbon or graphite. The preheated combustion air is supplied from the heat accumulator through an air conduit 21 connected thereto and an unexplained bottom air inlet of the secondary heating flue 18. The corresponding bottom air inlet of the intermediate heating year 18 can lead the exhaust gas into the connected heat accumulator and then reverse the direction of heating. The inlets 22 and 25 are used alternately as inlets or outlets.
