<p>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.</p> |
