To make the object, technical solutions and advantages of the present invention clearer, technical scheme of the present invention will be carried out below
Detailed description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
Embodiment：
As shown in Fig. 1~Fig. 2, present embodiments provides one kind and exempting from the online purge gas cleaner that stops, including cylinder
1, the top of the cylinder 1 is connected with end socket 2, and the lower section of the cylinder 1 is connected with the ash bucket 3 of taper, described
It is provided with medium inlet 101 on cylinder 1, net gas outlet 201 is provided on the end socket 2, the bottom of the ash bucket 3 is provided with
Cinder-discharging port 301.
Fixed plate 4 is provided in the cylinder 1, the lower section of the fixed plate 4 is foul smell chamber 5, the top of the fixed plate 4
For the areas Jing Qi, the medium inlet 101 is located at the lower section of the fixed plate 4, and installation settings has several groups tool in the fixed plate 4
There is the filter core 7 of inner cavity, the filter core 7 is located in the foul smell chamber 5 and the inner cavity of the filter core 7 is connected to the areas Jing Qi, often
Group filter core 7 is correspondingly arranged on back-blowing device 8.
It is four net air cavitys 6 that partition board 9 is provided in the areas Jing Qi by the areas Jing Qi even partition, each net air cavity 6
It is correspondingly arranged on one group of filter core 7 and a set of back-blowing device 8.
Gas containing dust is entered through medium inlet 101 in the foul smell chamber 5 of cylinder 1, and the gas containing dust is turbid
Other than in air cavity 5 into it is interior go out mode through filtration core 7, dust is trapped in filter by the filtering interception function through filter core 7 in cylinder 1
Outside core 7, the interior intracavitary that filtered air enters filter core 7 reaches the net air cavity 6 of the top of fixed plate 4 again, through on end socket 2 after
Net gas outlet 201 from net air cavity 6 be discharged；It is fallen under the effect of gravity in ash bucket 3 after dust accumulation that filter core 7 intercepts
The ash that 3 bottom deposit of ash bucket is discharged in cinder-discharging port 301 is opened when the dust of ash bucket 3 accumulates to a certain extent in bottom.
After filter core 7 works a period of time, dust accumulation, which is attached on filter core 7, leads to the net air cavity 6 of cleaner and foul smell
5 pressure difference of chamber is excessive, opens back-blowing device 8 at this time and is passed through purge gas to the inner cavity of filter core 7, into outgoing side within purge gas
Formula dispels the dust adhered on filter core 7 to foul smell chamber 5 through filtration core 7, i.e., has carried out blowback cleaning to filter core 7.
To ensure the normal work of production system, closes and need by the net gas of the corresponding net air cavity of clean one group of filter core 76
The net gas outlet 201 of outlet 201, the net air cavity of the other three 6 is in the open state, after the blowback cleaning of the net air cavity 6,
The net gas outlet 201 of the net air cavity 6 is opened, then blowback cleaning, production system sequentially are carried out to remaining 6 corresponding filter core 7 of net air cavity
System cleaner when running well successively cleans 6 corresponding filter core 7 of each net air cavity, does not influence production efficiency.

It is entered in gas distributor 10 through medium inlet 101.Effect through gas distributor 10 uniformly divides containing the air with dust
It is scattered in foul smell chamber 5, enables four net air cavitys, 6 corresponding four groups of 7 uniform filtering dust of filter core, single group filter core 7 is avoided to load
Big situation ensures the stable operation of cleaner.
Specifically, the back-blowing device 8 includes gas collecting tube 81 and pulse valve 82, and the gas collecting tube 81 includes 811 Hes of supervisor
Several branch pipes 812 being distributed on supervisor 811, the branch pipe 812 are correspondingly arranged with the filter core 7, and the pulse valve 82 is arranged
On the supervisor 811；Blowback air entrance 202 is provided on the end socket 2, the supervisor 811 is threaded through the blowback air and enters
In mouth 202.When specifically used, each branch pipe 812 corresponds to a filter core 7 and is arranged, and branch pipe 812 is made to stretch into the inner cavity of filter core 7, to
It is passed through blowback air in the supervisor 811 of gas collecting tube 81.When filter core 7 has dust accumulation obstruction after the fillter section time, in pulse valve 82
Under the action of, blowback air cleaning filter core 7 is blown into 81 fixed time intervals section of gas collecting tube into filter core 7.
The difference gauge 12 being provided with for detecting 5 pressure difference of net air cavity 6 and foul smell chamber is also connected on the cylinder 1；Further include
The control system being turned on and off for receiving the pressure difference signal control pulse valve 82 that difference gauge 12 detects, i.e. control system are adopted
The opening and closing of the pulse valve 82 are controlled with the mode that differential pressure controls.
When specifically used, when difference gauge 12 detects the smaller threshold value less than setting of pressure difference of net air cavity 6 and foul smell chamber 5
When, control system controls pulse valve 82 and closes, and the filter effect of filter core 7 is preferable at this time；When difference gauge 12 detects 6 He of net air cavity
When the pressure difference of foul smell chamber 5 is larger than the threshold value of setting, illustrate to have on filter core 7 more dust accumulation obstruction, at this time filter core 7
The poor needs of filter effect are cleaned, and control system receives the pressure difference signal control pulse valve that difference gauge 12 detects and opens at this time
It opens, blowback air enters gas collecting tube 81 and cleaned to 7 blowback air of filter core, until difference gauge 12 detects net air cavity 6 and foul smell chamber 5 again
Pressure difference be less than threshold value close pulse valve 82.
As further improvement of this embodiment, the control system can carry out adaptability in existing electric controller
Selection, as long as the opening and closing for accurately controlling pulse valve 82 can be realized.Preferably, the control system is controlled for PLC
System processed.

It rushes valve 82 to be distributed in a ring, the mode that time control also can be used in the control system controls unlatching and the pass of the pulse valve 82
It closes.The control system controls between each pulse valve 82 with certain time interval and certain anti-of each pulse valve setting
Blow the time.Per being spaced after a period of time, control system, which sequentially controls a pulse valve 82 and opens, starts blowback cleaning, when the pulse
When valve 82 opens certain blowback time, which closes, and four net air cavitys 6 sequentially clean corresponding filter core 7.
Further, control system is adopted when the priority of differential pressure control is higher than the priority, i.e. normal use of time control
Make the opening and closing that the pulse valve 82 of four net air cavitys 6 recycles with time control, sequentially cleans four groups of filter cores 7.If occurring turbid
Threshold value of the air cavity 5 with some 6 pressure difference of net air cavity higher than setting, then preferentially clean the 6 corresponding filter core 7 of net air cavity.
As further improvement of this embodiment, the ash bucket 3, which is also connected with, is provided with level-sensing device 11, when in ash bucket 3
Dust pile accumulated amount it is larger when, can open cinder-discharging port 301 be discharged dust.
As further improvement of this embodiment, the control system can also be by receiving the material that detect of level-sensing device 11
Position height controls the opening and closing of cinder-discharging port 301.
As further improvement of this embodiment, the back-blowing device 8 further includes air accumulator 83, is also set on the end socket 2
It is equipped with blowback air outlet 204, the air accumulator 83 is by pipeline through blowback air outlet 204 and the blowback air entrance 202
Connection.
