Detailed description of the invention
Core of the present utility model is to provide a kind of pulse bag type dust collector, and this pulse bag type dust collector can guarantee that it normally runs.
In order to make those skilled in the art understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, the sectional structure schematic diagram of the airway of the pulse bag type dust collector that Fig. 1 provides for the utility model embodiment.
The pulse bag type dust collector that the utility model provides, comprise upper box body, bag room that inside is provided with filter bag of dust collector, lower part box, soot cleaning system and ash exhauster; In addition, upper box body comprises air-purifying chamber and promotes casing, and bag room is positioned at the bottom of air-purifying chamber; Several locellus ash buckets 1 are provided with, as shown in Figure of description 1 in the bottom of airway.
On above-mentioned basis, airway is positioned at the below promoting casing, and is provided with inclined clapboard in airway, and inclined clapboard is inclined at the inside of airway, and airway is divided into air inlet and air outlet; Air inlet and air outlet lay respectively at the both sides of airway; In addition, be provided with shunting device in airway, this shunting device runs through inclined clapboard and arranges, and utilizes shunting device flue gas can be brought to air outlet from air inlet; Promote casing and be provided with lifting cylinder, this lifting cylinder stretches into airway inside, and can open the bypass valve of shunting device; This lifting cylinder is connected by the valve plate of rigid connecting rod with shunting device end, is controlled the opening and closing of shunting device by lifting cylinder.
Specifically, when needs shunting device 5 is closed, utilize lifting cylinder to be pressed down by valve plate, thus make shunting device 5 be in closed condition; Now, the actual flow of flue gas is to being air inlet--locellus ash bucket 1--lower part box (namely the ash bucket)--bag room--air-purifying chamber of upper box body--lifting casing of upper box body--air outlet, so, flue gas is just discharged from air outlet after the devices such as locellus ash bucket 1, ash bucket, bag room and air-purifying chamber complete filtration; When needs shunting device 5 is opened, utilize lifting cylinder to carry on valve plate, thus make shunting device 5 be in opening; Now, the actual flow of flue gas is to being air inlet--shunting device--air outlet; Adopt aforesaid way, the infringement that shunting device just can be utilized just can to avoid being in the flue gas under non-work condition state cause filter bag of dust collector, thus ensure the normal use of pulse bag type dust collector.That is, shunting device 5 is utilized to be to make flue gas without bag room, flue gas being directly expelled to air outlet by air inlet after shunting device 5.
Herein, it should be noted that, in order to the air inlet realizing the air-purifying chamber of upper box body is opened or closed, can lift valve be provided with, thus guarantee that the gas outlet of air-purifying chamber can open normally or close.
In addition, the end of shunting device 5 is provided with valve gap, rises cylinder and is connected with valve gap by rigid connecting rod, and the by-pass port of valve gap and shunting device 5 fits tightly; And valve gap comprises two-layer valve plate, between two-layer valve plate, pass through compressed air sealing.
Specifically, shunting device 5 is set to closed type valve; During the furnace lifting of debugging, trial run, close the louver valve of locellus ash bucket 1 and the lift valve of air-purifying chamber, the air outlet of the air inlet of bag room and air-purifying chamber can be closed.Such flue gas is without filter bag, and the shunting device 5 directly through deduster enters into next processing links, thus realizes the object of protection filter bag.
Moreover, when the inlet temperature sensor of pulse bag type dust collector detects that cigarette temperature exceedes the temperature range that filter bag of dust collector can bear (setting this temperature is 160 DEG C to 200 DEG C), the signal given by temperature sensor controls lifting cylinder 4, open shunting device 5, and the pipeline valve of closes compression air 7, pending fault solves, time in cigarette temperature drop to the normal tolerance range of filter bag of dust collector, close shunting device 5, pulse bag type dust collector at this moment just can normally run.
Moreover, when differential pressure transmitter detects that the pressure reduction of pulse bag type dust collector air inlet and air outlet is greater than setting value (setting the scope of this pressure at 1480Pa to 1520Pa) and can fall, the signal given by differential pressure transmitter controls lifting cylinder 4, the pipeline valve of closes compression air 7, open shunting device 5, fix a breakdown in time, when differential pressure transmitter detects that pressure drop drops in the scope of setting, close shunting device 5, pulse bag type dust collector at this moment just can normally run.
As can be seen from above-mentioned, in above-mentioned three kinds of situations, utilize shunting device 5 just can realize the normal operation of pulse bag type dust collector, avoid being in the infringement that the flue gas under non-work condition state causes filter bag of dust collector, thus ensure the normal use of pulse bag type dust collector, and extend the service life of filter bag.
For optimizing above-mentioned embodiment, pulsaire collector bag dust collector also comprises the Pressure gauge 6 of the pressure showing compressed air 7.That is, utilize Pressure gauge 6 can the sealing effectiveness of real-time monitored shunting device 5, and the pressure of compressed air 7 between two-layer valve plate just can be shown in real time by Pressure gauge 6.
On above-mentioned basis, filter bag of dust collector is vertically arranged on 2 bags of indoor; And filter bag of dust collector is flat bag or circular bag.Certainly, according to actual needs, the set-up mode of filter bag of dust collector and the shape design of filter bag of dust collector can have multiple different set-up mode, are not limited to described herein.
Above pulse bag type dust collector provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
