で除去する技術が要求される様になっている。[Prior Art] As a means for detoxifying harmful gas components or decomposing malodorous components in the air, a method is widely adopted in which a catalyst is supported on a honeycomb-shaped molded body and the air is passed through the honeycomb-shaped catalyst. All of the above honeycomb-shaped catalysts have a structure in which the to-be-treated gas and the catalyst are brought into contact with each other to remove harmful components, etc. from the to-be-treated gas while the to-be-treated gas passes through the pores of the honeycomb-shaped catalyst. . However, with this configuration, fine particles in the gas to be treated pass through the pores of the honeycomb without being completely captured, and in order to achieve a high dust removal function, it is necessary to increase the capacity of the honeycomb-shaped catalyst. It was necessary to take some contact time. Furthermore, in cleaning indoor air, especially in work involving the handling of precision electronic components, there is a growing need for technology to remove fine dust from the air with high efficiency.

反復使用の可能なものとなり更に効果的である。[Operations] The present invention is constructed as described above, but in short, the honeycomb-shaped laminate, which is a component of an electrostatic precipitator, is made of an electrically conductive sheet material, leaving gaps parallel to the gas flow direction. A
By alternately laminating one or more layers of electrically conductive sheet material B and applying a voltage between two adjacent electrically conductive sheet materials A-A, the electrically conductive sheet is formed. An electric field can be formed in the space between the materials A and A through the electrically semiconductive sheet material B. Since it can electrically capture fine dust in the air that has been charged in advance by corona discharge or the like using an electric field, it is ideal as a constituent material for a dust collector with high dust collection efficiency. That is, in this case, in terms of strong electrical engineering, the electrically semiconductive sheet material B acts as an insulating layer, and the electrically conductive sheet material A acts as a conductive layer (or electrode), but in terms of electrostatic engineering, it acts as an electrically conductive layer. Since the semiconductive sheet material B acts as a conductor, it distorts the electric field between the electrically conductive sheet materials A and A and inhibits the dust collection action without causing the accumulation of pre-charged dust charges thereon. Never. Further, by incorporating a catalyst substance into the sheet material, additional functions such as ozone decomposition, deodorization, and sterilization can be exerted. The honeycomb-like laminate described above is even more effective if the sheet material is made heat resistant so that it can be used repeatedly by heating and firing.

きる。The basic structure of the honeycomb-like laminate according to the present invention is as follows:
As shown in Fig. 2, the wavy sheet material 2 and the flat sheet material 1 are alternately laminated horizontally, or as shown in Fig. 3, the wavy sheet material 2 and the flat sheet material 1 are wound into a cylindrical shape. Any structure such as a laminated structure can be adopted.

(Thus, the wavy sheet material 2 is an electrically conductive sheet material B), and in FIG. 5, every other flat sheet material 1a is an electrically conductive sheet material A. (3 layers of electrically semiconductive sheet material B are interposed), in FIG. 6, every other wavy sheet material 2a
This is the electrically conductive sheet material A.

By laminating the electrically conductive sheet material A one layer at a time between one or more layers of the electrically semiconductive sheet material B, a honeycomb-like laminate optimal as a constituent material for a dust collector can be manufactured industrially. and can be manufactured at low cost.

し、本発明の構成であるとこうした問題も発生しない。In addition, since the honeycomb laminate used in the present invention applies a voltage between the electrically conductive sheet materials A, it is possible to uniformly conduct electricity between the electrical resistors located at a short distance, and to conduct electricity from both end faces of the ceramic. Compared to conventional so-called ceramic honeycomb heaters, catalytic heaters, etc., it can be used even at lower voltages and is safe and economical. In other words, as a technology for electrically heating and purifying gas, there are also known ceramic honeycomb heaters in which ceramic is made into a honeycomb shape and the entire ceramic is used as an electrical resistor, and catalytic heaters that exhibit functions such as ozone decomposition, deodorization, and sterilization. However, all of these methods apply high voltage to both ends of the ceramic to heat it with electricity, which requires high voltage, increases the cost of the power supply, and also poses safety issues. be. In contrast, with the configuration of the present invention, such problems do not occur.

用を阻害するからである。As the electrically semiconductive sheet material B used in the present invention, a sheet material such as ceramic paper containing a substance generally called electrically semiconductive such as silicon or titanium carbide or nitride or metal oxide can be suitably used. It is necessary that its specific resistance value is t x t o' to 1×10 13 Ωcm. If the resistivity value is less than txto'Ωcm, the electrically semiconductive sheet material B acts more as a conductor than as an insulator, allowing too much current to flow, resulting in excessive power loss. Moreover, if it exceeds lXl0''00m, electric charge will accumulate on the surface of the electrically semiconductive sheet material B, which will inhibit the dust collection effect.

It can also be used by changing the composition of the electrically semiconductive sheet material B, but other materials such as metal foil, conductive paper, metal,
A ceramic sheet mixed with graphite or the like can be used. Further, the specific resistance value of the electrically conductive sheet material A is appropriately set in relation to the specific resistance value of the electrically semiconductive sheet material B of the honeycomb-like laminate, but at least It needs to be 1/10 or less of the specific resistance value. If this exceeds 1/10, electrically conductive sheet material A
