Definitions

  • a device for reducing gaseous and particulate emissions into the atmosphere, especially useful in connection with the discharge of coke from the coke side of a coke oven battery includes an entrapment structure attached to and extending the length of the top of the coke side battery.
  • the structure has an enlarged top section which serves as an expansion zone for the gases.
  • the roof of the structure is formed by less than horizontal panels, and wall members depend from the roof panels to the coke quench car or below but do not touch the ground.
  • a tapered duct extends the entire length of the structure with air scoops suitably positioned to remove the finer fractions of particulates and thermal gases when the duct is placed under partial vacuum.
  • the invention relates to a device for collecting particulates and gases produced from thermal chemical reactions, and is particularly useful in connection with the collection of such products emitted into the atmosphere from the coke side of a coke oven chamber.
  • Each compartment would be obliged to accept the gas presthe oven and the volume represented by one compartment would not be able to accomodate the resulting increased volume of gases and the suspended particulates when the coke is pushed and the gases, including the atmosphere in front of the oven, increase by several orders of magnitude due to the high temperature of the coke (usually l ,800-2,000F.).
  • the compartment. even though it is under suction, is inadequate to accept the large increase in volume of the gases which are forced to migrate, as do the particulates, to either side of the particular compartment and enter the atmosphere outside of the hood. Also, this arrangement requires movable walls on the carriage of the coke guide.
  • this housing or entrapment area should be of a permanent or stationary nature and not be a part of the coke guide or coke quench car which should be permitted to move freely down their respective tracks laterally in front of the coke oven battery without being encumbered by the hoods, panels, suction ducts and other appurtenances described in the foregoing mentioned patents.
  • the present invention is directed to a device or apparatus for trapping or collecting the fumes and particulates which are normally discharged into the atmosphere in a variety of thermal chemical reactions.
  • the apparatus is particularly useful to accomplish these purposes in connection with the operation of a byproduct coke oven battery in that it can collect the fumes from leaking seals on or around the doors which enclose the ends of the coke ovens, and also it can collect the fumes and particulates that are formed when the coke is pushed from the ovens after each coking cycle.
  • Our device or apparatus includes a housing which extends the entire length of the emissions-generating apparatus, and particularly of a coke oven battery on the coke side thereof.
  • the housing has a peaked roof comprising end panels and less than horizontal roof panels which extend outwardly and downwardly from the peak of the roof and which are higher than the source of the emissions.
  • a peaked roof comprising end panels and less than horizontal roof panels which extend outwardly and downwardly from the peak of the roof and which are higher than the source of the emissions.
  • Depending from the lower portion or edge of the roof panels is at least one additional panel which extends inwardly and downwardly from the lower portion or edge of a roof panel over towards but terminating beyond the outerside of the quench car.
  • the upper zone of the apparatus defined by all of the aforesaid panels serves as an expansion zone which notonly helps to accomodate the thermal volume occupied by the hot gases generated when the coke is pushed from the oven but also affects the upward velocity of the emissions.
  • This upper zone also provides a space for altering the path of the upwardly rising hot gases and entrained particulates into acirculating pattern which assists in classifying the particulates into fine particles (ie less than about I micron) which are evacuated, and coarse particles which fall to the ground for periodic cleanup.
  • From the edges or lower portions of the aforesaid panels substantially vertical walls depend downwardly to the source of the emissions but they do not extend down so far as to prevent air from circulating across the bottom of the walls and upwardly through the housing.
  • a tapered suction duct is placed in the upper portion of the expansion zone of said housing.
  • the duct has a progressively increasing crosssectional area as it approaches the suction side of a fan at the end of the duct.
  • This duct is equipped with air scoops which project outwardly from the duct from openings therein and which are positioned in a manner to substantially balance the gas pressure throughout the duct when suction is applied thereto.
  • Suction means such as an in-line fan, are provided to produce a negative pressure in the duct to evacuate the finer portion of the particles and the gases from the thermal expansion zone at a controlled rate and balanced air flow, and the particulates are directed to a suitable scrubbing device.
  • a principal object of this invention is to provide an emissions collecting apparatus which is particularly suitable for being installed in existing byproduct coke plants without substantial structural changes being required, and which can be adapted to other industrial operations for control of emissions.
  • Another object of this invention is to'provide an emissions collecting apparatus which is integral with the coke side battery and which will cover the coke guide and quench car areas of a coke oven battery and which will extend the entire length of said battery and provide sufficient volume to accommodate the enlarging volume of gases caused when the hot coke is pushed from the oven while at the same time evacuating the fine fraction of the particles which rise to the top of the housing due to the thermal updraft and expanding volume of the gases.
  • Another object of the invention is to provide capability to entrap extremely hot pushing emissions, including particulate matter and also emissions escaping from coke side doors. More specifically, an object of the invention is to provide a unique design of entrapment to confine the massive thermal release attendant upon pushing an oven of incandescent coke while continuously providing the entrapment capability necessary to collect emissions from pushing operations and normal or abnormal leakage from coke side doors.
  • An additional object of the invention is to improve working conditions by removal of noxious fumes, gases, and particulate matter.
  • workmen in the entrapment area are provided highly desirable shelter from rain',:snow, wind, and hot summer sun.
  • FIG. 1 is a diagrammatic and perspective view, taken along the coke discharge side of a coke oven battery
  • FIG. 2 is a view along the line 2-2 of FIG. 1 showing, in cross-section, the emissions housing of the invention including the suction duct, as well as the coke guide and coke quench car.
  • FIG. 3 is a graph showing the thermal expansion effect on the atmosphere within the emissions housing of the invention when coke is pushed from a coke oven at a temperature of around I,800F.
  • FIG. 4 is similar to FIG. 2 but shows another modification of the invention.
  • FIG. 5 is a fragmentary perspective detail of the suction duct and air scoops which form a part of the inventIOn.
  • a coke oven battery generally designated by the numeral 10 having a plurality of parallel coke chambers or ovens 11.
  • a door llu which may be either self-sealing or which is luted, in accordance with the conventional practice, with a suitable clay or other refractory material to retain the gases insofar asis possible within the oven while the coal charge is being coked therein.
  • the top of the coke oven battery consists of a buckstay llb.
  • On the coke oven side of the battery and just directly beneath the individual ovens is a track or bench 12 on which a coke guide car is positioned.
  • the guide car is equipped with side panels 13a and moves laterally along the coke oven side on rails I4.
  • a quench car 15 On still a lower level beneath the guide car and also running laterally of the coke oven battery is a quench car 15 which moves on track 16. All of the aforementioned components are standard equipment and well known to those skilled in the art.
  • roof structure which is higher than the battery and which consists of roof end panels 220 at each end of the roof, and outwardly and downwardly extending roof panels 21 and 22.
  • the first roof panel 21 extends outwardly and downwardly above the top of the coke oven battery and is supported by columns 27b which rest on and are fixed to the coke oven buckstay to support this side of the roof structure.
  • the second roof panel 22 extends outwardly and downwardly beyond the coke guide and quench car. areas.
  • a third panel 23 depends downwardly and inwardly from the lower longitudinal edge of roof panel 22 toward the quench car area but terminating outside of this area.
  • a substantially vertical wall member 25 depends from the lower portion or edge of the first roof panel 21 down to the top of the coke oven battery buckstay 11b and preferably fits in a substantially gas tight fashion.
  • Another substantially vertical wall 24 depends downwardly from the lower portion of the panel23 to a posi- I which the quench car is positioned but is not in contact therewith in order that air currents may form a cross draft or upward draft inside of the housing structure when the coke is pushed from the oven, causing a thermal updraft within the housing.
  • the apparatus also requires, when used in connection with a coke oven battery, an inwardly and upwardly extending thermal shield 27 positioned above the coke guide area and which can be affixed to the columns 27b which support the roof panel 21.
  • This shield extends the entire length of the coke battery and may be constructed of steel with insulation such as calcium or magnesium silicate affixed to the underside and/or both sides.
  • the area above this thermal shield or deflector panel 27 and under the roof panel 21 serves as a portion of the expansion zone B in the upper portion of the housing.
  • This thermal deflector panel or shield 27 is affixed to the supporting columns 27b at one end and is supported from the roof truss 30 by means of a suspension rod 27a.
  • the roof panels 21, 22 and the panel 23 may be constructed of any suitable high temperature resistant material including corrugated alloy steelor tempe ratuFe resistant vinyl-asbestos panels.
  • the vertical wall panels 24 and 25 may also be constructed of steel or other rigid, high temperature resistant material, or they may be constructed of woven asbestos blankets or panels which can be reinforced and/or secured together by monel wire or other high temperature resistant wire.
  • the emissions entrapment structure 20 also includes end panels 24 and 26 which are constructed of materials similar to panels 24 and 25.
  • the quench car travels along the track 16 in a right to left direction in the views shown in FIGS. 1 and 3 and therefore the wall or panel 26 must have a suitable hinged flap 32 or door which can be pushed up or opened if this panel extends below the level of the quench car in order that it may leave the structure on its way to the quench tower.
  • the emissions entrapment structure is also equipped in the upper area of the thermal expansion zone with a temperature resistant duct 28 which can be round, square, rectangular or other configuration. As is shown in the drawings, this duct is progressively tapered and has an increasing cross section as the duct approaches the suction side of a fan 29. When the enlarged portion of the duct leaves the emissions entrapment structure it is preferably provided with a transition piece 35 and a tubular duct portion 35a which leads to the fan 29.
  • the particulate matter which passes through the fan is led to a gas scrubbing device or dust filtration apparatus which may be of the centrifugal or cyclone type or to an electrostatic precipitator. These are conventional devices and are not shown on the drawings. Alternatively, these devices may be positioned ahead of the fan 29.
  • FIG. 5 shows an enlarged portion of a section of the exhausting duct 28 and the air scoops 28a which are positioned over openings therein.
  • these scoops are formed by cutting diagonally a piece of pipe of a suitable diameter and each section of this cut pipe is welded to an opening in the duct in a manner such that the leading edges of the scoops 2811 are opposed to the direction of air flow in the duct produced when the fan 29 draws a suction on the duct.
  • This provides a streamline flow of the gases and particulate material through the scoops and through the duct in the direction of the fan.
  • the duct holes and air scoops are appropriately placed in the duct so as to substantially equalize the static pressure in the duct throughout the length thereof to provide reasonably uniform exhaust throughout the length of the emissions entrapment structure.
  • the emissions entrapment structure 20 is supported by structural members 17, 18 and 27b on the outside of the structure and by structural members 30 and 31 on the inside of the overall structure.
  • the fan 29 is also supported by suitable structure.
  • FIG. 3 shows the thermal expansion of the gases within the emissions entrapment structure 20-when about 1 1 tons of coke, at a temperature of around 2,000 F are pushed from an oven in less than 1 minute into the quench car 15.
  • the peak thermal volume or load, represented by area A-4, reaches its maximum in less than 1 minute. This depends on the ram travel time A-l, i.e., the time required to push the coke from the oven into the quench car, the coke temperature, and the retention time A-2 of the quench car within the structure.
  • the desired clearing time of the housing can be calculated and the diameter of the suction duct 28 and the capacity of the fan 29 can be determined.
  • Fan 29 is operated continuously and at a suitable volumetric flow (shown as A-3 in FIG. 3), a total time shown as A5 elapses to clear the thermal volume emission A-4 from the entrapment structure.
  • a large portion of the expanded gas volume is reversed in flow in the upper portion of the entrapment structure and is directed back downward into the portions or areas of the upper structure defined by the roof panels 21 and 22, the panel 23 and the thermal deflector panel 27.
  • the gases containing particulate matter are initially di rected upwardly in the main thermal updraft in the center portion of the thermal expansion zone.
  • the finer particles i.e., those finer than about 1 micron, are directed upwardly toward the duct 28 and into the duct through the air scoops 28a and then downstream in the duct toward the exhaust fan 29 and thence to a scrubber of the type previously described.
  • the temperature resistant panels or walls 24, 25 and 26 contain the thermal load and also allow air to move under these wall panels to produce a cross draft and an upward draft of the thermal load into the expansion zone.
  • the thermal load per volume generated by a given amount of coke pushed from the oven canbe determined by placing the quench car into an enclosed structure such as a quench tower, and measuring the velocity of the upwardly directed gases and their temperatures at various portions inside the closed structure. This produces a figure which approximates the volume of the hot gases produced by a given quantity of coke.
  • the emissions entrapment structure is then constructed of suitable proportions to contain this volume but must have the upper structure previously described in order to provide the expansion zone for the thermal volume and circulation of the hot gases and particulate matter in the desired fashion and to provide a partial classification and fallout of particulates in the manner described.
  • an emissions entrapment structure which will accomodate about 400,000 cubic feet of gas at the maximum temperature which is reached within the structure when the coke is pushed at a temperature about l,800F., is provided.
  • the entrapment structure will be 176 ft. long and the 45 roof panels 21 and 22 will be ft. and 22 ft. long, respectively.
  • Panel 23 will be about 7 ft. in length. The entire roof structure overhangs the coke guide and quench car areas.
  • the duct 28 will vary in cross-sectional area, and will have a dimension at the far end of the emissions entrapment structure of 3 ft. by 6 ft. and a dimension of 6 ft. by 6 ft. at the suction end of the structure.
  • Fifty-nine air scoops 28a are provided and these are constructed from 14 inch diameter round pipe by cutting the pipe diagonally and fitting each scoop to one of 59 holes cut out of the duct. These are so positioned that the static gas pressure in the duct is substantially balanced throughout the duct when suction is applied.
  • a 6 ft. diameter in-line fan having a capacity of about 140,000 cfm is employed, driven by a 200 horse power motor.
  • the wall 24 and the end panels 26 are suspended or positioned so that the bottom edge thereof is either at about the same level of, or slightly above the top of the coke quench car, or they can be in a position just above the grade on which the track for the quench car has been laid.
  • the apparatus of the invention can also be used in connection with other industrial operations employing a high temperature chemical reaction such as a blast furnace, electric steel furnace, etc.
  • the supporting structure for the emissions entrapment housing will have to be changed to suit the particular installation requirements. Therefore, the invention can be used in connection with many operations other than that specifically described herein.
  • an apparatus for collecting particulate emissions discharged into the atmosphere in the presence of high temperature gases produced by a high temperature chemical reaction which includes a noncompartmented stationary housing defining an emissions entrapment zone positioned to receive such emissions and having a peaked roof including end panels and outwardly and downwardly extending first and second roof panels which are higher than the source of said emissions, the first of said roof panels extending from the peaked roof to a point over or beyond the source of said emissions, and the second roof panel extending from the peaked roof in a direction away from the source of said emissions, the lower edge of the roof panels also being higher than the source of said emissions, and a suction duct positioned at or near the apex of the roof, the improvement which comprises providmg:
