Claims
- 1. The combination of a coke oven battery having a plurality of coke ovens in side-by-side relation, a track paralleling the coke oven battery on the coke side and a quench car traveling on said track into which hot coke is pushed selectively from the coke ovens of said coke oven battery, a hood traveling on a track, suspended over the quench car, and movable into close overhead registry therewith, an exhaust duct paralleling and coextensive in length with the cokeoven battery, said exhaust duct comprising water trough means which is coextensive to said exhaust duct, wherein the improvement comprises a lateral U-shaped extension duct on said hood through which emissions collected in said hood flow to the exhaust duct, said U-shaped extension duct comprising an upstream section and a downstream section, the downstream section being smaller in cross-sectional area than the upstream section and providing a venture-like restriction to flow of emissions from the said hood to said exhaust duct across which a pressure differential exists, and a water pressure system including a series of nozzles in the upstream section of said U-shaped extension duct for laterally projecting a spray of water into the flow of emissions immediately in advance of the restriction provided by said downstream section, to effect a blending of said spray with said emissions to produce a cooling and a cleaning of said emissions prior to entry into said exhaust duct.
- 2. The combination according to claim 1, wherein said water pressure system comprises a pump and a motor for driving said pump carried on said hood, a water intake pipe via which said pump withdraws water from said water trough means, a pair of parallel extending header pipes located on opposite sides of the upstream section of said extension duct to which said pump delivers water under pressure, said nozzles being disposed in spaced relation along and connected to said header pipes.
- 3. The combination of a coke oven battery having a plurality of coke ovens in side-by-side relation, a track paralleling the coke oven battery on the coke side, a quench car traveling on said track into which hot coke is pushed selectively from the coke ovens of the coke oven battery, a hood traveling on a track suspended over the quench car and being movable into close overhead registry therewith, said hood acting to collect emissions including smoke, fumes, gases and particulates arising from hot coke deposited in the quench car upon being pushed out of the coke side of said ovens, a water trough paralleling the coke oven battery and divided into two separate longitudinal areas, the space over one of which is enclosed and constitutes an exhaust duct, the space over the other being open to atmosphere, said hood having a U-shaped lateral extension the distal end of which is submerged in the water trough and open into said exhaust duct to enable emissions to flow from said hood to said exhaust duct, the bottom of said water trough being sloped laterally to a low point and having drains at the said low point via which particulates that collect therein from the emissions are removed, the improvement comprising a multiple of high pressure water jet nozzles carried on said U-shaped lateral extension and aimed to agitate said particulates and skim the collected solids from the bottom of said trough to enable them to be removed via the drains in said trough, and a water pressure system for supplying water under high pressure to said jet nozzles.
- 4. The combination according to claim 3, wherein said water pressure system comprises a pump carried on said hood, an intake pipe for said pump extending into the area of said water trough open to atmosphere, and a delivery pipe communicating pressurized water from the said pump to said jet nozzles.
