Definitions
- the invention relates to a method for discharging dry-cooled coke from a coke cooling shaft, the coke being withdrawn from the coke cooling shaft and then from the coke disc continuously or in batches via non-gas-tight extraction devices, preferably by actuating discharge rockers arranged uniformly over the cooling shaft cross section gastight system is removed and a device for performing this method.
- the invention is therefore based on the object of proposing a method and a device for discharging dry-cooled coke of the type defined at the outset, which are improved with regard to the problems described.
- a gas-tight, wear-resistant discharge system with a low overall height and low investment costs should also be obtained.
- Claim 9 contains a device for performing the method. Preferred embodiments are given in claims 10 and 11.
- the cooled coke is then extracted from a preferably square or rectangular coke cooling shaft z. B. by actuating discharge rockers discontinuously and discharged via a cellular lock which ensures the gas-tight closure, preferably via a drum lock equipped with two lock chambers.
- each of the two lock chambers of the drum lock can be at least the one thrown off a discharge rocker
- the amount of coke thrown from a discharge rocker can be accommodated in one of the two lock chambers of a two-chamber drum lock, the drum lock not being moved during the coke discharge over the discharge rockers arranged above the drum lock and this being emptied first, so ⁇ as soon as the last coke has reached the receiving lock chamber from the discharge rocker actuated.
- the drum lock When the drum lock is actuated, it is pivoted through 180 °, so that the entire coke, which had previously reached the lock chamber which is ready to receive via the discharge rocker, falls out downwards and z. B. is discharged in a metered manner via a subsequently arranged vibration channel.
- the movement and thus the emptying of the two-chamber drum lock is locked with the actuation of the discharge rockers in such a way that the lock chamber is only emptied after the coke flow has come to a complete standstill via the respective discharge rocker.
- coke-side overshoot and thus overfilling of the two lock chambers with wear of the housing wall and any sealing strips due to clamped coke pieces is prevented at all times.
- the invention alternatively provides that the discontinuously withdrawn coke is fed with the aid of a vibrating trough to a continuously operating cellular wheel sluice with a large number of sluice chambers.
- the vibrating trough can be arranged above the cell wheel lock for the transition to the continuous further transport of the coke and, on the other hand, below the drum lock.
- a residual cushion of coke can form on the vibrating channel in the discharge funnel, which can also contain the quantity of several coke batches thrown off with the discharge rockers.
- This residual coke is expediently monitored by level probes and regulated by changing the discharge quantity in the vibratory trough and the rotary valve. In any case, it should be ensured that between the discharge rockers and the upper edge of the residual coke pad in the discharge funnel there is a free space for the even addition of the cooling gas below the discharge rockers.
- the invention provides that the sheet metal dividing the sluice in two chambers is connected on the outside to circular segments or other side plates adapted to the circular part of the housing shell, which are also rotated by 180 ° when the sluice chambers are emptied.
- These circular segments form a largely gastight seal with respect to the housing jacket. They are at least as large as the inlet and outlet openings of the drum lock. This ensures that the cooling gas, which is under pressure above the lock, cannot flow directly to the outside during the emptying or rotation of the lock chambers.
- FIGS. 1 and 2 show the two-chamber drum lock (4) according to the invention with the vibration channel (5) arranged underneath and in FIGS. 3 and 4 the arrangement of the vibration channel (17) above a rotary valve (18).
- the coke is usually cooled in the cooling shaft by a circulating cooling gas.
- the cooled coke is withdrawn in a metered manner at the end of the square or rectangular cooling shaft via the curved coke chutes (2) and by alternately actuating the discharge rockers (3), a large number of discharge rockers being evenly distributed over the shaft cross section.
- the entire coke bed rests on a sort of sieve tray, with the cooling gas below the discharge rockers (3) being distributed evenly over the cross-section of the cooling shaft.
- the actuation of the discharge rockers (3) is controlled via the final coke temperature.
- the coke falls directly and completely from the discharge rockers (3) via the outlet funnel (9) into the upper chamber (13) of the drum lock (4) which holds the coke.
- the inner movable part of the drum sluice with the sheet metal (12) and the circular segments (15) attached to it are rotated by 180 ° around the central horizontal axis of rotation, the coke being released from the chamber which now releases coke ( 14) onto the vibration channel (5) underneath and from there evenly to a conveyor belt (6) for further transport.
- the two-chamber drum lock shown in FIGS. 1 and 2 is characterized in that the essentially circular drum space of the drum lock (4) is divided into two lock chambers by a flat plate (12) which can be rotated about a central horizontal axis. So that the coke does not come into contact with the inner wall of the circular part of the casing (16) and grinds along it when the drum lock is actuated, circular segments (16) which are adapted to the circular part of the casing (16) are attached to the ends of the sheet (12). 15) or similar side panels attached.
- cooling gas can be prevented from escaping through the introduction of inert gas (N ⁇ application (11)) at the inlet port of the drum lock.
- the vibrating trough is arranged directly under the discharge funnel (9) in order to ensure an even application to the To ensure cellular wheel sluice (18).
- two vibrating troughs (17) and the associated cell wheels (18) and the conveyor belts (6) can also be arranged next to one another.
- the discharge funnel (9) is constructed in such a way that all of the coke thrown off the coke discharge rockers (3) can be removed either from one or the other vibrating channel.
- a needle slide (21) can be arranged in the outlet funnel (9).
- E REPLACEMENT LEAF (8) for the coke cooling shaft (1) is supported on the supporting walls (7).
- the drum sluice (4) with the further transport organs for the coke is expediently supported separately, a compensator (10) being attached to compensate for expansion between the discharge funnel and the drum sluice (4).
