The utility model discloses a kind of multistage filtering devices for radioactive waste gas treatment belongs to waste gas treatment device technical field, and it includes base, box and positioning ring, box is fixedly connected on the upper surface of base, positioning ring is fixedly connected in box inner wall, positioning ring upper surface is overlapped with support frame, support frame surface is fixedly connected with filter screen bag, it has beneficial effect, this one is used for multistage filtering device of radioactive waste gas treatment, by setting filter screen bag and air extractor, when staff needs to filter dust in waste gas, staff only needs to connect the one end of connecting pipe with inlet pipe, then operates air extractor by control switch control, to be able to draw radioactive waste gas into box interior, under the cooperation of filter screen bag, it is convenient for staff to filter dust carried in radioactive waste gas, avoid the blockage damage caused by water pump used when staff handles radioactive waste gas.

This invention discloses an environmentally friendly, low-emission bag filter dust collector, relating to the technical field of bag filter dust collectors. The dust collection box has several mounting seats evenly embedded at equal intervals at its top. An outer frame tube is threaded onto the outer side of the bottom of each mounting seat, and an inner frame tube is threaded onto the inner side of the bottom of each mounting seat. An outer bag is fitted onto the outer side of the outer frame tube, and an inner bag is embedded into the inner wall of the inner frame tube. Several through slots are formed at equal angles along the circumference at the top of the mounting seat corresponding to the position between the outer and inner frame tubes. This invention can construct a dual-channel dust collection path and a synchronous dust removal path. During dust collection, the dust collection pressure is monitored in real time, enabling automatic switching between the two paths. This indirectly achieves uninterrupted dust collection and continuous dust removal, improving the compatibility and stability between dust collection and dust removal operations, enhancing the dust collection effect, reducing the wear rate of the outer and inner bags during operation, extending their effective service life, and indirectly improving their endurance stability and working efficiency.

The utility model provides a kind of treepaper carton processing trepanning device, by first conveyor belt, trepanning mechanism, second conveyor belt sequentially arranged along the direction of conveyance, and then the treepaper paperboard constituting carton is conveyed from first conveyor belt to trepanning mechanism and is trepanned, after being sent out by second conveyor belt, realize the full automation of treepaper paperboard, trepanning and discharging processing, to improve the trepanning efficiency when treepaper carton is processed, improve economic benefits.Simultaneously, by setting dust hood to be sleeved outside output assembly, avoid the dust generated when trepanning to be scattered to working environment and be inhaled by human body, cause damage to the health of operator;Simultaneously set negative pressure fan to carry out suction treatment to dust emitted in dust hood in time by suction pipe and dust suction pipe, avoid too much dust to overflow to dust hood outside or dust to deposit on conveying assembly, cause conveying assembly to be blocked and damaged, guarantee the use safety and use efficiency of device, improve service life.

The utility model belongs to the technical field of heat accumulating type oxidation furnaces, in particular to a heat accumulating type oxidation furnace with a heat exchange device, which comprises a base, an oxidation furnace main body is fixedly connected to one side of the top of the base, a transmission pipe is fixedly connected to the top of the oxidation furnace main body, one end of the transmission pipe is fixedly connected with a heat exchange device main body, and the other end of the transmission pipe is fixedly connected with the heat exchange device main body.
