Description

  The present invention relates to a harmful substance detoxifying device for detoxifying harmful substances such as dioxins.

Conventionally, for example, used filter cloth used in a filtration dust collector is incinerated in an incinerator in the facility where the dust collector is installed, or entrusted to an industrial waste disposal contractor with a certain license for industrial waste disposal. Then, it was put into an ash melting furnace and processed or disposed of by landfill.
In addition, as a method for removing dioxins by the inventors of the present application, a method for removing dioxins by irradiating microwaves or ultraviolet rays at an appropriate place in the transportation piping when transporting the fly ash transported by gas in the piping has been proposed.

In order to minimize the adverse effects of dioxins on the human body in recent years, since December 1, 2002, “Ministerial Ordinance on Standards and Measurement Methods for the Amount of Dioxins Contained in Soot and Dust Related to Waste Incinerators” The concentration of dioxins contained in waste is regulated to 3 nanograms or less per gram of dust collection ash, and in principle, dioxins are also removed from landfilled waste. It became necessary to take measures to do.
In view of the above, an object of the present invention is to provide a harmful substance detoxifying device that detoxifies harmful substances such as dioxins with simple equipment.

  In order to achieve the above object, the harmful substance detoxifying device of the present invention is adjacent to the detoxifying device for detoxifying harmful substances having a plurality of microwave irradiation mechanisms for irradiating the inside of the casing with microwaves. The microwave irradiation mechanism is arranged such that the irradiation ports are perpendicular to each other.

According to the harmful substance detoxifying apparatus of the present invention, harmful substances such as dioxins can be reliably rendered harmless by microwave irradiation.
And by arranging the adjacent microwave irradiation mechanisms so that the respective irradiation ports are at right angles, the reflected microwaves go back to each other's irradiation ports and destroy the inside of the microwave irradiation device. It is possible to effectively prevent the microwaves from interfering with each other.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a harmful substance detoxifying apparatus according to the present invention will be described below with reference to the drawings.

  FIG. 1 shows an overall view in which the harmful substance detoxifying device of the present invention is applied to a used filter cloth detoxifying device.

  The used filter cloth detoxification device 1 includes a housing 4 having an open lower surface on a transfer mechanism 3 that transfers a used filter cloth roll R, and the inside of the housing 4 is separated from a partition wall 5 and a ceiling. 8, the inside of the housing 4 is partitioned, and a shielding ceiling 6 having an open lower surface is provided below the partition wall 5, and the shielding ceiling 6 is shielded from the transition direction of the used filter cloth roll R. The shielding member 7 is suspended, and the space defined by the shielding ceiling 6 and the shielding member 7 is defined as a shielding room B, and the space defined by the ceiling 8 and the partition wall 5 is configured as an irradiation chamber A.

A microwave irradiation device 2 is provided on the ceiling 8 of the irradiation chamber A.
In addition to providing one microwave irradiation device 2 in one room, when two microwave irradiation devices 2 are provided in one room, the irradiation ports are perpendicular to each other as shown in FIG. Deploy as follows.
This is because when the irradiation ports are arranged in parallel, the reflected microwaves may go back to each other and destroy the inside of the microwave irradiation device 2.

  As shown in FIG. 3, the transfer mechanism 3 uses a belt conveyor or the like as shown in the figure, and arranges the used filter cloth rolls R so as to regularly and alternately enter the irradiation chamber A and the shielding chamber B. As shown in FIG. It is preferable to provide 3 ′.

  The shielding member 7 is an example of a noren-shaped curtain, but is not limited thereto, and may be an iron shutter. In this case, the shutter is configured to open and close in accordance with the transfer of the transfer mechanism 3. .

  Reference numeral 9 denotes a pusher for pushing the used filter cloth roll R onto the transfer mechanism 3, and it is preferable to use a hydraulic / pneumatic cylinder or the like.

  In the above configuration, the used filter cloth rolls R used in the filtration type dust collector are arranged in front of the pusher 9 by appropriate means, and pushed into the housing 4 of the detoxification device 1 by the pusher 9 to thereby enter the detoxification device 1. The used filter cloth roll R is fed into the detoxifying device 1 while opening the shielding member 7 'of I.

  The used filter cloth roll R fed first passes through the first shielding chamber B and is fed into the first irradiation chamber A. At this time, the second used filter cloth roll R enters the first shielding chamber B, and the used filter cloth roll R in the irradiation chamber A is rendered harmless by the microwave irradiated from the microwave irradiation device 2. The

  According to experiments by the inventors and others to make the used filter cloth roll R harmless, in the case of one used filter cloth roll R of 5 kg, irradiation for 5 minutes is performed by a 10 kW microwave irradiation device 2 (micro transmitter). When the transfer mechanism 3 is driven and the used filter cloth rolls R are sequentially sent out of the last shielding chamber B, the used filter cloth rolls R become detoxified filter cloth rolls R ′. It is sent and conveyed to the outside of the detoxifying device 1 while pushing open the shielding member 7 ″ provided at the outlet O of the detoxifying device 1 and stored in the storage box 10 as appropriate.

  FIG. 4 shows an example in which the above-described used filter cloth detoxification device 1 is placed on the mobile conveyance vehicle 20. In this example, in addition to the power supply for driving the conveyor of the transfer mechanism 3, microwave irradiation is performed. As a power source for operating the apparatus 2, a battery provided in the transport vehicle 20 can be used.

  As described above, the harmful substance detoxification device of the present invention has been described based on the example applied to the used filter cloth detoxification device, but the present invention is not limited to the configuration described in the above example, The configuration can be changed as appropriate without departing from the spirit of the invention.

  Since the harmful substance detoxification apparatus of the present invention can detoxify harmful substances such as dioxins with simple equipment, microwaves including those for processing harmful substances such as dioxins are used. It can be widely used in processing equipment.

It is a side view which shows the whole detoxification apparatus of the used filter cloth to which the detoxification apparatus of the harmful substance of this invention is applied. It is a top view which shows a part of detoxification apparatus of the used filter cloth. It is a side view which shows the detail of the transfer mechanism of the detoxification apparatus of the used filter cloth. It is a side view which shows the example which mounted the detoxification apparatus of the used filter cloth in the vehicle for conveyance.
