Description

The proposed annular battery of coke ovens of continuous action consists of a series of annular coking chambers arranged in a ring, having heating channels on the outer and inner sides and a regenerative or recuperative device located in the center of the battery and intended for heat recovery of waste combustion products; in addition, the battery is provided with an annular gas line, a barrel plate and a coke screen.

In FIG. 1 shows a vertical section of a battery along the junction of the heating channels and at the coal supply site; FIG. 2-cross section of the battery (with recuperators); FIG. 3 is a section along I - // in FIG. 2; FIG. 4-expanded view of I / -I / with a cut.

Channels are shown for the conspicuity due to the width of the regenerators). The proposed battery of coke ovens of continuous operation has an annular coking chamber 2 (Fig. 1), an inner ring of heating channels 3 and an outer ring of heating channels 4; regenerators or recuperators 5 are located in the center. Charging coal into the coking chamber is made through a turnstile / and coke -through a roller screen 12, guiding it to a circular conveyor / 5 for transferring through point 14 to a transport tube 15 in which the coke is cooled by air or an inert gas. An additional gas LL serves as an annular gas line 6, and for a heating gas — an annular gas line 7. Gas is withdrawn from the coking chamber through stations 9 into the barrel 8 mounted on supports 10, which are attached to the anchorage 11. The latter is tied together by the height of the battery gami on convolutional couplings.

When pressing coke under the coking chamber 2, a press 12a is installed with a coke dosing unit, transferring the briquettes to the circular conveyor 13a. The briquettes are subjected to additional heating for the final removal of carbohydrates.

Air or oxygen required for burning the heating gas can be heated the heat obtained from quenching the coke is supplied to the internal heating channels through the support channels b to the common annular channel 7; Air or oxygen is supplied to the external heating channels through pipe 8 to the support cavity 9 and to the annular channel / ft. Gas is supplied to the external heating channels by arranging the annular gas pipelines in the required places; when supplying gas to the internal channels, the gas pipeline // must be located outside the zone of high temperature of the furnace, and gas must be supplied to the burners using separate tubes J2; The same system for supplying gas and air can also be used for heating through a wall, if the regenerators are located outside the furnace.

In all furnace heating options, coke oven gas is supplied purified.

PROPOSAL SECTION.

1. A ring battery of coaxial continuous furnaces. This is due to the fact that it consists of a number of radially arranged coking chambers, equipped on both sides with internal and external heating channels 3, 4, a turnstile /, a ring gas pipeline 6, 7, a rack plate 8, a screen for coke-12 and a device for utilization of heat-waste from waste products of combustion.

2. The form of the device according to p. 1, characterized in that for the purpose of heat recovery of waste combustion products, it is provided with a regenerative device 25, 24 concentrically located in a ring battery, connected by means of a valve 29, channels 26 and 32 and openings 27 with vertical heating channels 4-4a, 21 and 5-Over.

3. The form of the device according to p. 1, characterized in that for the purpose of heat utilization of waste combustion products it is provided with recuperative devices 23, 24 connected through channels 25, 26 and apertures 27, 29, concentrically arranged in a ring battery vertical heating channels 3, 21 vi 4.

4. The form of the device according to p. 1, characterized in that the heating vertical channels I, 2, 3 are directly connected to the coking chamber 4 in order to carry out the coking process by internal heating.
