Abstract
It is intended to provide a blasting treatment apparatus which can prevent dispersion of a hazardous substance or the like to the exterior with a simple structure. To achieve this object, a blasting treatment apparatus (1) comprises a pressure container (10) including an outer vessel (31) and an inner vessel (32) and a suction device. The outer vessel (32) has a first sucking part (17) and a second sucking part (18) for interconnecting the interior and the exterior of the outer vessel (31) at an end thereof opposite to a pressure-resistant lid (11) and in an upper wall. The inner vessel (32) has an interconnect hole (16) for interconnecting the interior and the exterior of the inner vessel (32) at a location thereof corresponding to the first sucking part (17). The first sucking part (17) and the second sucking part (18) are located at positions where gas in the inner vessel (32) can be sucked by the suction device and the gas released from the inner vessel (32) through an inner opening (32a) can be sucked from a gap between the upper wall of the outer vessel (31) and the inner vessel (32).
