A coke oven monitoring system capable of quantitatively monitoring changes in the state of the furnace walls in a coke oven with good accuracy has: an oven width measurement device (6) that measures the oven width; an in-furnace observation device (7) that photographs the oven walls; and a computer (10) that analyzes oven width data measured by the oven width measurement device, and oven wall image data captured by the in-furnace observation device. The computer is characterized by including: a oven width/oven wall image data extraction unit (10a) that extracts width data and oven wall image data in different extrusion cycles for the same location of the same kiln; and an oven width/oven wall image data analysis and processing unit (10b) that determines oven wall abnormalities when the oven width data and oven wall image data obtained in the current extrusion cycle have both changed relative to the oven width data and oven wall image data obtained in past extrusion cycles in such a manner as to exceed established values.A coke oven monitoring system capable of quantitatively monitoring changes in the state of the furnace walls in a coke oven with good accuracy has: an oven width measurement device (6) that measures the oven width; an in-furnace observation device (7) that photographs the oven walls; and a computer (10) that analyzes oven width data measured by the oven width measurement device, and oven wall image data captured by the in-furnace observation device.

An oven observing equipment capable of observing the inside of an oven turned to a high temperature precisely includes: a housing 13 having an intake part for cooling air, and a discharging part for discharging the cooling air after being used for cooling; and an imaging device 20 contained in this housing 13 near the discharge part. This imaging device 20 is composed of integrated combination of an image sensor 16; plate-like thermoelectric cooling elements 18a to 18d arranged in a state that their heat-absorbing faces surround the periphery of a body of the image sensor; thermoconductive blocks 17a to 17d embedded in the gaps between the image sensor body and the thermoelectric cooling elements 18a to 18d; and cooling fins 19a to 19d formed on the heat-radiating faces of the thermoelectric cooling elements 18a to 18d are integrated with each other.

A coke-oven repairing apparatus comprising: a traveling carriage 3 which travels in the direction of coke oven battery with the carriage straddled on the rails placed on the top of a coke oven; a traversing carriage 4 provided on said traveling carriage 3, which moves in the direction orthogonal to the direction of coke oven battery; and a working device 5 for making repairs on the oven walls within the coke oven which is mounted on said traversing carriage 4, wherein the working device 5 includes: a guide post 31 which stands on the traversing carriage 4, and is also coupled, at its lower end portion, to a supporting portion provided on the traversing carriage through a pivot shaft 42; a lance 32 which ascends or descends along the guide post 31; and a derricking device 45 which tilts the guide post 31 between a forward-tilted posture and a backward-tilted posture using the pivot shaft 42 as the fulcrum to oscillate the lance 32 inserted in a coke-oven carbonizing chamber through a charging-hole, within the carbonizing chamber.
摘要:
The present invention provides a biological treatment method of biologically treating the subject water containing phenol, thiocyanate and the like, which improves the quality of treated water, while suppressing a reduction in treatment efficiency. As a means for achieving the aforementioned object, the present invention relates to a biological treatment method including introducing subject water containing a COD component, wherein the COD component is at least one of phenol and thiocyanate, into a biological treatment tank containing sludge containing bacteria capable of decomposing the COD component to thereby biologically treat the COD component with the bacteria, wherein, before the introduction of the subject water into the biological treatment tank, a step of counting the total number of bacteria contained in the sludge is carried out, so that the amount of the COD component loaded on a single bacterium per unit time can be controlled within a predetermined range.
