The second filtering device comprises a second supporting frame and a second metal net in the second supporting frame.

The third filtering device comprises a third supporting frame and flame-retardant non-woven fabrics in the third supporting frame.

The second expanded metal density is greater than the first expanded metal density.

A first open slot for the first support frame to be drawn out and inserted is arranged at the position, corresponding to the first filtering device, of one side surface of the filtering cavity, a second open slot for the second support frame to be drawn out and inserted is arranged at the position, corresponding to the second filtering device, of one side surface of the filtering cavity, and a third open slot for the third support frame to be drawn out and inserted is arranged at the position, corresponding to the third filtering device, of one side surface of the filtering cavity; and the side surface of the filter tower close to one side of the first, second and third open grooves is provided with an access door.

The utility model has the advantages that: particulate matter in to waste gas filters and the oil smoke through first filtering component, and the oil smoke in the waste gas is further got rid of to rethread second filtering component afterwards for outer exhaust gas filter effect is better.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Wherein: FIG. 1 is a schematic structural view of the present invention;

in the attached drawing, 1 is a tower body, 2 is a flue, 3 is a filter chamber, 6 is a pattern plate, 7 is a filter cartridge, 8 is a first support frame, 9 is a second support frame, 10 is a third support frame, 11 is a first slot, 12 is a second slot, 13 is a third slot, 14 is an access door, 15 is an air storage tank, and 16 is an air inlet pipe.

Detailed Description

Referring to fig. 1, a filter tower for an incinerator comprises a tower body 1, a flue 2, a first filter assembly and a second filter assembly; a filter cavity 3 connected with the flue is arranged at an inlet of the lower part of the tower body, the first filter assembly is positioned in the filter cavity, and the second filter assembly is positioned at the upper part of the tower body; the first filtering assembly comprises a first filtering device, a second filtering device and a third filtering device which are arranged in the filtering cavity in sequence; the second filter assembly comprises a pattern plate and a plurality of filter cartridges 7 which are uniformly distributed on the pattern plate 6. Particulate matter in to waste gas filters and the oil smoke through first filtering component, and the oil smoke in the waste gas is further got rid of to rethread second filtering component afterwards for outer exhaust gas filter effect is better.

The third filtering device is arranged at the end part of the outlet of the filtering cavity. Set up the tip at the filter chamber export with the third filter equipment, can effectively filter on the one hand, on the other hand sets up the ash that falls that the device can avoid in the filter tower at the tip and gets into the flue.

The first filtering device comprises a first supporting frame 8 and a first metal net arranged in the first supporting frame. The metal mesh filters particles, and the metal mesh can be made of stainless steel and has longer service life.

The second filter device comprises a second support frame 9 and a second metal mesh in the second support frame. The metal mesh filters particles, and the metal mesh can be made of stainless steel and has longer service life.

The third filtering device comprises a third supporting frame 10 and a flame-retardant non-woven fabric in the third supporting frame. The adoption of the flame-retardant non-woven fabric can effectively filter the oil smoke in the waste gas.

The second expanded metal density is greater than the first expanded metal density. Because the density of the first metal net is small and the mesh holes are large, the first-stage filtration of the waste gas from the furnace body is realized, and larger particles are blocked; the second metal mesh holes are smaller than the first metal mesh holes, and the waste gas subjected to primary filtration is subjected to real-time secondary filtration to further filter particles of the waste gas.

A first open slot 11 for the first support frame to be drawn out and inserted is arranged at the position, corresponding to the first filtering device, of one side surface of the filtering cavity, a second open slot 12 for the second support frame to be drawn out and inserted is arranged at the position, corresponding to the second filtering device, of one side surface of the filtering cavity, and a third open slot 13 for the third support frame to be drawn out and inserted is arranged at the position, corresponding to the third filtering device, of one side surface of the filtering cavity; and the side surface of the filter tower close to one side of the first, second and third grooves is provided with an access door 14. Through setting up first, second, third fluting and access door, realize the demountable installation of first, second, third carriage, make things convenient for better and the maintenance in later stage.

And a blowing system is arranged on one side of the tower body above the second filtering component. And a blowing system is arranged to blow and clean the filter cartridge.

The blowing system comprises an air storage tank 15, a plurality of air inlet pipes 16 are uniformly distributed on the air storage tank, a plurality of nozzles are uniformly distributed on the insertion end of each air inlet pipe inserted into the tower body, and the nozzles correspond to the filter cartridges one by one; and a pulse valve is arranged at the joint of the air inlet pipe and the air storage pipe. The gas is blown to the filter cartridge through the nozzle on the gas inlet pipe.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
