摘要： PROBLEM TO BE SOLVED: To enable prolonged continuous operation with a higher efficiency of retarded combustion by arranging pin-shaped protrusions for preventing sliding down of wastes fed at a specified interval on the internal wall of a rotary kiln to effectively stir up the wastes therein. SOLUTION: Pin-shaped protrusions 14 are arranged on the internal wall surface of a rotary kiln 10 along a spiral opposite to the direction of rotation of the rotary kiln. By the reverse spiral is meant a spiral state in which an action is developed to send wastes 18 upward against the downward movement of the wastes 18 when a cylinder body 11 is rotated in a specified direction. With the formation of the protrusions, one mass of the wastes 18 lifted up by the pin-shaped protrusions 14 is pushed back slightly toward to the front side with the rotation of the rotary kiln 10 thereby enabling the extending of retention time within the cylinder body 11. This enables effectively stirring up of the wastes 18 thereby achieving an efficient and sufficient retarded combustion.

摘要： PURPOSE:To simplify equipment and to decrease the reflying of collected dust by installing a dust discharge means in the lower part of a dust collector through a cutoff valve, arranging a portable closed dust storage/transfer means that is attachable to and detachable from the dust discharge means and connecting the dust discharge means and the inlet side part of the dust collector by a pressure equalizing piping. CONSTITUTION:A dust collector body 1 and a discharge hopper 4 are connected by a pressure equalizing piping 7 having a stop valve 6 When the dust collected and deposited in a lower hopper 2 of a dust collector body 1 is discharged, first the stop valve 6 is opened to equalize the pressure in the dust collector body 1 with that in a tank lorry 5. Next, swing valves 3 incorporated into upper and lower discharge hoppers 4 are opened to discharge the collected dust collected and deposited in the lower hopper 2 into the tank lorry 5. As a result, the collected dust is discharged, completely sealed from outside the system and since the equalization is made, reflying dust contg. gas flows to the inlet side of the dust collector through the pressure equalizing piping. Therefore, the lowering of dust collecting performance due to reflying of dust is not caused.

摘要： PURPOSE:To make it easy to replace filter cloths by contracting filter cloths suspended from a ceiling plate in a bag chamber vertically, then taking the cloths together with the ceiling plate out of the bag chamber, and instead, suspending another filter cloths prepared previously from the ceiling plate to introduce the cloths in a contracted state into the bag chamber. CONSTITUTION:Filter cloths suspended from ascendable ceiling plates 2A to 2E in bag chambers 6A to 6E are allowed to contract vertically all at once, and then are taken out of the bag chamber together with the ceiling plates 4A to 4E through a delivery outlet 9A. Instead, another filter cloths prepared previously are suspended from the ceiling plates 2A to 2E, then are introduced in a contracted state into the bag chambers 6A to 6E, and are elongated vertically. Thus time required for the replacement of the filter cloth is shortened significantly. In addition, a working environment can be improved as the filter cloths are given a maintenance service outside the bag chamber. That is, simplifying the work to set the temperature of a working site, operation in a clean ambient due to partial dust collection, remove the filter cloth using well- maintained replacement equipment and install the filter cloth is achieved.
