Description
Technical field
The invention belongs to the industrial dedusting technical field, especially relate to a kind of interior cone structure that has, the filter cartridge dust remover of the high uneven distribution of filtrate pleat.
Background technology
Along with China's rapid economy development; With resource, energy resource consumption property be the master heavy chemical industry (electric power, metallurgy, building materials, chemical industry etc.) development rapidly; The problem of environmental pollution that thereupon brings is also serious day by day; In numerous pollutants, solid particulate matter particularly fine particle becomes the emphasis that the urban atmospheric pollution thing is prevented and treated.Country has formulated strict emission control standards to flue dust in the industrial circle and dust, in thermal power plant's atmosphere pollutants emission standards of up-to-date promulgation the discharge standard of flue dust is brought up to 30mg/m
3(Environmental Protection Department, 2011).Because electrostatic precipitator is lower than the arresting efficiency of higher particle and fine particle to fly ash resistivity; Be difficult to reach emission request; Sack cleaner makes moderate progress with respect to electrostatic precipitator concerning the arresting efficiency of particle, but also exist ultrafine dust is collected difficult, high, filter bag run-down, the defectives such as ash-removal effect is poor, operating cost height easy to wear of filtration velocity.
In recent years, along with the continuous development of new technology and new material, make filter cartridge dust remover be widely used in industrial circles such as cement, chemical industry, iron and steel, metallurgy, electric power.Filter cartridge dust remover is compared with electrostatic precipitator with sack cleaner, has advantages such as filter area is big, pressure reduction is low, volume is little, long service life.See that from development trend filter cartridge dust remover will become the effective means that control subparticle pollutant emission concentration reaches national environmental standard fully.
The core component of filter cartridge dust remover---filter cylinder is a kind of cylindrical structure, and its inner core is a metal framework, and the outside is the folding filtrate of one deck.Filter cartridge dust remover work during to certain phase the pulse deashing device will carry out deashing to each filter cylinder.Can induce a large amount of secondary gas flows to enter into cartridge interior from the high-speed gas of nozzle ejection during deashing filter cylinder is carried out reverse gas cleaning, but conventional filter cylinder exists the excessive and drawback of bottom deashing energy shortage of filter cylinder top deashing energy when deashing.Top deashing energy is crossed conference and is caused the filtrate deashing of this part more thorough; When filtering, can attract more gas flow so next time; Thereby cause the media filtration load of this part to increase relatively; If things go on like this, the filtrate on filter cylinder top will shift to an earlier date the damaged service life that consequently has influence on whole filter cartridge dust remover; The bottom too small meeting of deashing energy makes the normal deashing of filtrate of this part; Can't play normal filtration when filtering in next stage like this; Reduced the filter area of whole filter cylinder to a certain extent; Increased the filtration load of other part filtrates of filter cylinder, so also can cause reduce the service life of whole filter cartridge dust remover.This conventional structure of filter cylinder makes that the deashing energy has wasted on filter cylinder top greatly; And arrival filter bag when bottom deashing energy is not enough to filtrate is carried out normal deashing, and the uneven distribution of this deashing energy will have influence on the service life of whole filter cartridge dust remover.
Simultaneously, conventional filter cartridge dust remover adopts single import intake method more, and single import intake method is because air-flow has certain initial velocity when just having got in the deduster; Air-flow can produce one jet; Gas Jet when running into the rear end face of deduster within it portion form one and laterally stream, the filter cylinder of one side will receive the transversal flow of dust-contained airflow in the windward side like this, it is bigger with respect to lee face one side that it filters load; If things go on like this can cause the filtrate of filter cylinder windward side one side damaged in advance; Thereby the filter efficiency of deduster is reduced, influence the service life of deduster, increased the production cost of enterprise simultaneously.
Summary of the invention
The present invention is directed to the technical problem that prior art exists, propose a kind of filter cartridge dust remover with interior cone structure, the high uneven distribution of filtrate pleat.
A kind of filter cartridge dust remover with cone structure filter cylinder provided by the present invention comprises casing, filter cylinder 7, card 10, air inlet 1, air outlet 2, pulse valve 8, gas bag 9 and pulse jet pipe 6; Said casing has upper box 3, middle casing 4 and lower box 5; Be provided with pulse jet pipe 6 and air outlet 2 in the said upper box 3, said gas bag 9 links to each other with pulse jet pipe 6 through pulse valve 8; The top of casing 4 is provided with card 10 in said; The bottom of casing 4 is provided with air inlet 1 in said; Said filter cylinder 7 is hung on said card 10, and said pulse jet pipe 6 is positioned at the top of filter cylinder 7, and each export center top of said filter cylinder 7 is facing to a nozzle of pulse jet pipe 6; Said filter cylinder 7 inside are provided with cone structure, and the filtrate of forming said cone structure is identical with the outside filtrate of filter cylinder.
Angle between the bus of said cone structure and filter cylinder 7 vertical directions does
β, said angle
βScope be: 5 °≤
β≤30 °.
The high windward side of the pleat of said filter cylinder 7 outside filtrates one side is higher than lee face one side, and has windward side one side filtrate pleat high
HBe lee face one side filtrate pleat height
h1.1 to 1.5 times.
The invention has the advantages that:
Owing to increase a kind of cone structure in cartridge interior, this structure reduces the cartridge interior space from top to bottom gradually, and the deashing energy also successively decreases from top to bottom, and this structure makes that the suffered from top to bottom deashing energy of whole filter cylinder is even basically; Next is that the material that cone adopted that cartridge interior increases also is a filtrate, has so just increased the filter area of filter cylinder; Windward side one side filtrate pleat height height a bit can increase the filter area of filter cylinder simultaneously, the short use that a bit can reduce material of lee face one side filtrate, and this structure can make the filtration of whole filter cylinder load relatively even.Filter cartridge dust remover provided by the present invention can improve the filter efficiency of deduster on the one hand, reduces the volume of equipment, can prolong the service life of deduster on the other hand.
