示されている。PRIOR ART The present invention generally seeks to recover moist aerosol from the exhaust gases produced in the manufacturing process, but in order to recover moist aerosol, it has hitherto been necessary to use a square or cylindrical shape with glass fiber packets. A filter was being used. Cylindrical filters are used for remote control, especially for high levels of radioactive exhaust gases, such as wet or dry aerosols. This filter consists of a filter frame and an annular fiber packet. The diameter and height of the filter are arbitrarily selected. The gas flows into the filter through an opening provided on one end face side of the casing (the other end face side is closed by a lid) sealed by the filter casing, and then flows into the filter, and the fiber of the filter insert is inserted. Flow through the layers.
The fiber packet filter is thus washed with water during operation, whereby the filter material is automatically washed by washing off the entrapped particles. The nozzle and the water distributor for this cleaning device are part of the filter casing and are connected to the filter insert when the filter insert is replaced. In this case, the sprayed liquid reaches both the gas inlet side and the gas outlet side of the filter and must be discharged separately from the gas in order to prevent short circuiting of the gas path. In order to obtain a high filter effect and keep the pressure drop in the filter low, the velocity change of the gas passing through the fiberglass packet must be within certain limits.
The filter surface provided thereby defines the maximum gas flow rate through the filter. A cleaning device for a filter stand is disclosed, for example, in DE-OS 3012911.

を大きくするために多層の構造にすることはできない。Known filter inserts of the type mentioned at the outset do not have an integrated spray system. The nozzle for cleaning the filter material is a component of the filter casing. When the filter becomes clogged, the filter casing, which is generally designed for a service life similar to that of the device, must be replaced at high cost.
Further, in such a casing, since the filter layer is fixed to both end surface sides of the filter material, it is not possible to form a multilayer structure in order to enlarge the filter surface.

ルタ挿入体の構成部分である。Effects According to the configuration of the present invention, the filter insert is configured as a self-cleaning moisture separator, whereby exhaust gas generated in the manufacturing process is forcibly guided through a filter packet made of glass fiber wool, Moist aerosol is collected. The filter insert has the shape of two concentrically arranged cylindrical layers, connected at the bottom to a packet of equal thickness made of fiberglass wool, so that the filter insert is moved upwards by a nozzle. Washed from. The gas flows from bottom to top through the gas inlet of the filter insert and is radially deflected at the top,
The distribution chamber between the two cylindrical fiber layers is reached. The gas then traverses the fiber layer, at which time moist aerosol is collected in the glass fiber packet and further gas flows downwardly from the filter insert through an annular opening in the bottom of the filter insert. Flow out.
When the filter pressure difference due to the load on the filter material reaches a predetermined value, the filter material is automatically or manually operated by the cleaning device of the invention, which is a built-in component incorporated in the filter insert. To be washed. At this time the aerosol collected in the filter packet is washed off by the liquid and removed with the liquid from the filter insert. As a result, the filter insert is cleaned and a new good filter action is obtained. The liquid distributor and the actual spray nozzle are part of the filter insert according to the invention.
