Description
Technical field
The utility model relates to a kind of deduster, especially relates to a kind of sack cleaner.
Background technology
Deduster be equipment that dust is separated from flue gas deduster or cleaner, its performance with accessible gas flow, gas drag losses and the efficiency of dust collection during by deduster express.Deduster is facility commonly used in boiler and the industrial production.
Deduster is divided into following five classes by its action principle: (1) mechanical precipitator comprises gravitational precipitator, inertial dust separator, centrifugal deduster etc.; (2) Washing dust remover comprises water-bath type dust cleaner, foam type deduster, venturi tube duster, water film type duster etc.; (3) filtration dust catcher comprises sack cleaner and gravel bed filter etc.; (4) electrostatic precipitator; (5) magnetic dust collector.Wherein, sack cleaner is most widely used cleaner.
Existing sack cleaner is in dust removal process, and the dust of assembling on the cloth bag inwall is difficult for dropping, and causes easily obstruction, needs often cleaning; In addition, in the course of work of sack cleaner, need manually carry out the judgement of cloth bag congestion situations, waste time and energy and also the result unreliable, cause efficiency of dust collection low.
The utility model content
For the deficiency that prior art exists, the utility model provides the sack cleaner that a kind of cost is low, efficient is high.
A kind of sack cleaner, described sack cleaner comprises casing and blowing device, casing is rack-mount, described sack cleaner also comprises control system, described casing comprises lower box, middle casing and upper box, be provided with ash bucket in the described lower box, ash bucket top is provided with air inlet, be provided with some row's filter bags in the middle casing, be provided with the pure qi (oxygen) passage in the upper box, the pure qi (oxygen) passage is communicated with filter bag, and the port of export of pure qi (oxygen) passage connects blowing device, one end of upper box is provided with air outlet, the blowing device connection control system.
Preferably, described blowing device comprises pulse valve and gas bag, and described pulse valve comprises Small diaphragm-piece and the large diaphragm that from top to bottom arranges, and pulse valve connects gas bag.
Preferably, the position corresponding to air inlet is provided with baffle plate in the described casing.
The utility model is reasonable in design, simple in structure, has energy-saving consumption, good dedusting effect, cleaning efficiency advantages of higher.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model blowing device.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, Fig. 2, a kind of sack cleaner, it comprises casing 1, blowing device 2 and control system 3, casing 1 is installed on the support 4, casing 1 comprises lower box 5, middle casing 6 and upper box 7, be provided with ash bucket 8 in the lower box 5, ash bucket 8 tops are provided with air inlet 9, and the position corresponding to air inlet 9 in the casing 1 is provided with baffle plate 10, be provided with some row's filter bags 11 in the middle casing 6, be provided with pure qi (oxygen) passage 12 in the upper box 7, pure qi (oxygen) passage 12 is communicated with filter bag 11, and the port of export of pure qi (oxygen) passage 12 connects blowing device 2, one end of upper box 7 is provided with air outlet 13, blowing device 2 connection control system 3.
After dusty gas was entered by ash bucket 8 top air inlets 9, under the effect of baffle plate 10, air-flow upwards flowed, and flow velocity reduces, and the part big dust particle falls into ash bucket 8 because the effect of inertia force is separated.Dusty gas enters middle casing 6 through the filtration, purification of filter bag 11, and dust is delayed at the outer surface of filter bag 11, and purified gas enters upper box 7, is discharged by air outlet 13.
Along with filter bag 11 surface dusts constantly increase, the sack cleaner inlet outlet pressure differential also rises thereupon.When the sack cleaner resistance reached setting value, control system 2 was sent the deashing instruction, and soot cleaning system is started working.At first pulse valve 14 is opened after receiving signal immediately, the compressed air of Small diaphragm-piece 16 top air chambers is discharged, because the stressed change in Small diaphragm-piece 16 two ends, the exhaust passage of being closed by Small diaphragm-piece 16 is opened, and the compressed air of large diaphragm 17 top air chambers thus passage is discharged, the large stressed change in diaphragm 17 two ends, make large diaphragm 17 actions, the delivery outlet of closing is opened, and the compressed air in the gas bag 15 sprays in the filter bag 11 via efferent duct 18, realizes deashing.After control signal stopped, pulse valve cut out, and Small diaphragm-piece, large diaphragm reset in succession, and winding-up stops.
Claims (3)
