Abstract
An enclosed quenching car movable along a battery of coke ovens and adapted to receive coke from each oven in succession and quench it without polluting the atmosphere. The car includes an enclosure containing a pivotal quenching tank with interior dimensions substantially corresponding to the dimensions of the carbonized coke cake to be accommodated therein. One side of the pivotal tank is formed from a water-permeable grid such that the coke cake within the tank can be rotated into a horizontal plane and the coke completely immersed in water passing through the permeable grid; while dust and gases are extracted without polluting the atmosphere. In this manner, the coke is quenched in such a way that it is yielded in large pieces with a defined uniform water content in the coarse and fine coke.
Claims8
A coke quenching apparatus including the combination of a quenching car movable along a battery of coke ovens and adapted to receive and quench a carbonized coke cake from said ovens, said car carrying a substantially gas-tight enclosure having door means at opposite ends thereof, a quenching tank disposed within said enclosure, said quenching tank being generally rectangular and having interior dimensions corresponding substantially to those of a coke cake to be quenched, one side of the tank being solid and one side being formed from a water-permeable grid, at least one end of the tank comprising door means to permit passage of a coke cake therethrough, water spray means in the enclosure adapted to spray water uniformly over the tank, and means for rotatably mounting the tank in the enclosure for movement between a vertical position wherein the sides of the tank are vertically disposed for receiving or discharging coke and a horizontal position for quenching the coke in which said solid side is below said water-permeable grid, whereby said water passes into the tank through said grid and is retained in the tank to completely immerse the coke cake.
