A card which is arranged in the horizontal direction divides a box body into an upper part air purifying space and a lower part filtering space; two plane separation plates vertically extend in the vertical direction from the lower surface of the card, and the space between the two separation plates is of an air course, and a space between the separation plate and the box body is of a bag chamber, and a guide plate divides the air course into a passage with an air inlet and a passage with an air outlet, and the air inlet is directly communicated with the filtering space, and the air outlet is communicated with the air purifying space through an air outlet branch opening on the card, and a plurality of filtering bags are hung in the bag chamber. Through the above technical proposal, the card divides the box body into the air purifying space and the filtering space, and the filtering space is divided by the separation plate into the air course and the bag chamber, and the air course is separated by the guide plate into the passage with the air inlet and the passage with the air outlet, so that the dust is filtered by the filtering bag in the bag chamber through the air inlet, and the clean air passes through the air outlet branch opening to the air outlet so as to complete the collection of the dust.

Description

Bag filter
Technical field
The utility model relates to a kind of environmental protection cleaner, relates to a kind of bag filter specifically, mainly is used on the dust catching of cement industry toxic emission point, also may be used on iron and steel, machinery, metallurgy, the dust catching of industry similar applications such as building materials.
Background technology
China is manufacture of cement and consumption big country, and cement output accounts for the over half of the world, and the dust emission of cement industry is a major reason that causes atmosphere pollution.China to the discharging of dust traditional be to adopt cottrell more, but fast development along with domestic economy, improving constantly and the enhancing of people's environmental consciousness of living standard, the environmental protection policy of country requires in line with international standards, traditional cottrell can not satisfy environmental protection requirement, and cost is higher comparatively speaking.
Summary of the invention
The purpose of this utility model provides the high and lower-cost bag filter of a kind of integrated efficient.
For achieving the above object, the utility model has adopted following technical scheme: the card that horizontal direction is arranged is separated into the pure qi (oxygen) space on top and the filter space of bottom with casing, below card, run vertically down two smooth dividing plates, space between two dividing plates is the air channel, space between dividing plate and casing is the bag chamber, deflector is divided into path that contains air inlet and the path that contains air outlet with the air channel, air inlet directly communicates with filter space, air outlet props up mouth by the air-out on the card and communicates with the pure qi (oxygen) space, and bag hangs some filter bags in the chamber.
As shown from the above technical solution, the utility model is separated into pure qi (oxygen) space and filter space with card with casing, with dividing plate filter space is divided into air channel and bag chamber, with deflector the air channel is divided into path that contains air inlet and the path that contains air outlet again, dust is filtered through the filter bag in the bag chamber by air inlet, and dust falls, and clean gas props up mouth to air outlet through filter bag by the air-out on the card, thereby finish the collection to dust, not only integrated efficient height but also cost are low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of bag filter is made up of casing, air inlet 22A, air outlet 22B, card 30, dividing plate 21, ash bucket 50 etc.The card 30 that horizontal direction is arranged is separated into casing the filter space 20 of the pure qi (oxygen) space 10 and the bottom on top.Below card 30, run vertically down two smooth dividing plates 21, the edge, upper end of dividing plate 21 links to each other with card 30, the edge, lower end is lower than the bottom of filter bag 40 and leaves the space with bottom half, dividing plate 21 is separated into air channel 22 and bag chamber 23 with filter space 20, space between two dividing plates 21 is air channel 22, space between dividing plate 21 and casing is bag chamber 23, the rectangle deflector 221 that tilts to be installed in the air channel 22 is divided into air channel 22 in path that contains air inlet 22A and the path that contains air outlet 22B, one end of deflector 221 is fixed on and is higher than air inlet 22A position suitable for reading and leaves the gap with card 30, and the other end is fixed on position that is lower than air outlet 22B end opening and the lower surface that is higher than dividing plate 21; Bag hangs some filter bags 231 in the chamber 23, and card hole and the card 30 of the top of filter bag 231 on card 30 fixes; The pure qi (oxygen) space 10 of bag 23 corresponding cards, 30 tops, chamber is separated into a plurality of air-purifying chambers 12 by dividing plate 11, the top of each air-purifying chamber 12 is equipped with pulse jet system 40, pulse jet system 40 can work independently, when promptly an air-purifying chamber 12 being carried out deashing, remaining air-purifying chamber 12 can also work on; The card 30 of 22 tops, air channel is provided with the air-out that communicates with air outlet 22B and props up mouthfuls 31, and air-out is propped up mouthfuls 31 top and is provided with lift valve 13, and lift valve 13 can cut out or open air-out and prop up mouthfuls 31, controls itself and being communicated with of air outlet 22B; Air inlet 22A directly communicates with filter space 20, and the pure qi (oxygen) space is propped up mouthfuls 31 by air-out and communicated with air outlet 22B; The casing lower end is connected with the ash bucket 50 of bell mouth shape.
Specific operation process is as follows:
During operate as normal, dusty gas is entered by air inlet 22A, along with air flow slows, part bulky grain grit strikes deflector 221 and directly falls into ash bucket, all the other most of grits enter each bag chamber 23 along with air-flow rises, after 231 filtrations of the filter bag in the bag chamber 23, grit is trapped in the outside of filter bag 231, purified gas passes filter bag 231 is entered top by the card hole of filter bag 231 inside on card 30 pure qi (oxygen) space 10, air-out on card 30 is propped up mouth 31 and is entered air outlet 22B again, thereby realizes dust collection.
Along with constantly carrying out of filtering, the resistance of bag filter also rises thereupon, and ventilation reduces, and need carry out deashing to it, and deashing is finished by pulse jet system 40.During deashing, the pulse valve of the pulse jet system 40 of air-purifying chamber 12 tops is sent into compressed air stream in the filter bag 231, filter bag 231 is the drum account rapidly, produce strong shake, cause the dust in filter bag 231 outsides to be shaken off, reach the purpose of deashing, in this process, the air-out of corresponding air-purifying chamber 12 correspondences is propped up mouthfuls 31 and will be raised valve 13 and fall and close.。
Aforesaid bag filter, filtration by filter bag 231, grit is trapped in the ash bucket 50, purified gas passes filter bag 231 inside and props up mouthfuls 31 through air-out and enter air outlet 22B, when deashing, but pulse jet system 40 separate operatons do not influence the work of all the other air-purifying chambers 12 in air-purifying chamber 12 deashings, this dust-precipitator adopts regularly deashing control, but off-line ash-clearing and online ash removal are switched.In sum, the utility model replaces original cottrell with bag filter, not only integrated efficient height, and with respect to cottrell, more economical.
