Description
Technical field
The utility model relates to the board-like filter core of a kind, particularly a kind of board-like filter core of class that is used for the dry method dust of various dusty gases.
Background technology
At present domestic and international dusty gas dry method dust, most sack cleaners that adopt.Sack cleaner has its advantage, and promptly relatively low, the cloth bag A wide selection of colours and designs of cost, efficiency of dust collection are high.These characteristics are characteristics decisions of cloth bag filtrate, are the difficult and analogies of other dedusting methods.But sack cleaner is being deposited significant disadvantages, mainly contains: 1. volume is big, and floor space is big; 2. leak detection difficulty is changed difficulty; 3. the purge gas consumption is big; 4. cloth bag is fragile, and the life-span is short.Above-mentioned shortcoming, by the cloth bag structures shape, these shortcomings are restricting the application of sack cleaner.
Cause short reason of cloth bag life-span to be: general cloth bag is made into rectangular bag shape, fixes by support and casing, and there are several garden rings support upper and lower side and centre, and cloth bag is fixed on these garden rings.Cloth bag is filtering and in the blowback cycle, is bearing very large tension force, and encircles friction with fixing garden, when the conversion of filtration and blowback, cloth bag produces bending, long friction and bending in fixing position, the contact point of cloth bag and support grinds leakage easily, and leak source is enlarged rapidly.As long as one the cloth bag mill leaks, can influence the filtration of whole box body.So the sack cleaner life-span is short is that structure by cloth bag causes.The bag shaped structure of cloth bag makes the filter area of every cloth bag limited, and the volume of sack cleaner is very big, and the purge gas consumption is big.
Each casing of sack cleaner has only a pure qi (oxygen) outlet, and the gas of all cloth bag filtrations all is pooled to an outlet, causes sack cleaner leak detection difficulty.
The drawbacks limit of sack cleaner the application on big-and-middle-sized blast furnace, and increased difficulty to maintenance management.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at sack cleaner, and a kind of efficiency of dust collection height is provided, and can make the board-like filter core of class that the deduster volume is little, the life-span long, the purge gas consumption is little, operating cost is low, the leak detection replacing is convenient, be convenient to maintenance management.
The purpose of this utility model is realized by following mode:
The utility model comprises discharge, flanged plate, gasket seal, upper head plate, flexible filtrate, on discharge, be provided with pure qi (oxygen) body outlet, it is characterized in that: flexible filtrate two sides is provided with protecting wire net and the outer protecting wire net of metal in the metal, in the metal, in outer protecting wire net and flexible filtrate are fixed on, between the outer grid, form the filter core main body, in, outer grid is the rigid structure of continuously arranged rhombus or approximate rhombus, making the filtering surface of flexible filtrate be with the central axis is the wavy shaped configuration of symmetry, and the zone that each rhombus or approximate rhombus surround constitutes filters cavity, the upper end and the upper head plate of filter core main body are fixed, upper head plate is connected with discharge by flanged plate, gasket seal is located between upper head plate and the flanged plate, and the side at discharge is connected with the filter core main body at least, at upper head plate, gasket seal, be equipped with and filter the corresponding pure qi (oxygen) body of cavity passage on flanged plate and the discharge, the lower end of filter core main body is sealed with press strip.
The utility model has the advantages that: adopt rigid structure, alleviate or eliminated the friction and the bending of filtrate; The metal inner and outer protecting wire net decomposes single grid with filtrate at the pressure that filters and bear during blowback, and the pressure that filtrate is born reduces significantly.This structure improves the life-span of filtrate greatly.Having eliminated the shortcoming of sack cleaner effectively, is a kind of desirable dusty gas dry method dust filter element.The deduster of making of this filter core has following characteristics:
1. efficiency of dust collection height; Can reach 99.99%;
2. the deduster volume is little, and floor space is half of sack cleaner;
3. the deduster life-span long, be 2～3 times of cloth bag;
4. the purge gas consumption is little, and for cloth bag half, operating cost is low;
5. the leak detection of this filter core is changed conveniently, is convenient to maintenance management.
