Description
Technical field
The utility model is related to a kind of deashing device, and in particular to a kind of pulse dust collector ash removing device.
Background technology
Pulse dust collector ash-removal effect directly affects efficiency of dust collection, and the compressed gas source that conventional deashing is used passes through water-oil separating
Device is carried out, and the setting well can not separate moisture content from source of the gas, cause filter bag easily hardened in pulse dust cleaning, at place
During the ash-laden gas that reason boiler is produced, this phenomenon is more obvious, causes equipment running resistance to increase, and has a strong impact on pulse dust removal
The dust removing effects of device；The utility model patent utilization compressed gas source, the active force produced by inverted draft is carried out clearly to cloth bag
Ash.
Utility model content
The purpose of this utility model is to provide that a kind of ash-removal effect is good, safe and reliable to operation, can extend filter bag uses the longevity
A kind of pulse dust collector ash removing device of life and raising filter bag dust removing effects.
A kind of pulse dust collector ash removing device, including pulse control instrument, pulse valve filter bag, gas bag, injection tube, air compressor machine；
Described pulse control instrument controls to control the unlatching of valve and pulse valve；Venturi tube persuader is provided with described filter bag；Institute
Multiple injection holes are provided with the injection tube stated；Described pulse valve one end is connected with gas bag, and one end is connected with injection tube；It is described
Air compressor machine through air cleaner filter after be connected with gas bag；Described pulse valve back pressure chamber connection control valve.
When pulse control instrument sends signal, control valve control Exhaust Open, the gas outside pulse valve back pressure room is released,
Pressure reduction, pulse valve film two sides produces pressure difference, diaphragm that displacement is produced because of differential pressure action, and pulse valve is opened, now compressed
Compressed air is entered gas bag by machine after air cleaner, sprays to be formed once through the injection hole in injection tube by pulse valve
Wind, when high velocity air enters filter by Venturi tube persuader induction of formation Secondary Air after being several times as much as the surrounding air of First air
Bag, makes filter bag drastically expand, by the inverted draft that the impact shock of Secondary Air and the gas absorbed with filter bag opposite direction are formed
To carry out deashing treatment to filter bag.
Moisture trap is provided between described gas bag and pulse valve, greasy dirt, moisture in gas bag is prevented through pulse valve
It is blown into filter bag；The settable multiple of described filter bag；Founder is to filter bag under described injection hole, it is ensured that gas is blown into filter bag；
When designing the injection hole of injection tube, the tolerance of injection hole pitch-row is ± 0.5mm, and injection hole should be vertically downward, it is impossible to
Incline, the vertical≤0.4mm of its axial line, otherwise blast pass can wash away filter bag；Arcuate socket resistance with flange is smaller, this
Injection hole not only reduce system injection resistance, and can make compressed air stream try one's best be compiled in some injection, in case air-flow diverging it is unordered
Filter bag is washed away, the possibility of filter bag is washed away so as to be reduced from structure.
The utility model patent is sprayed compressed gas by pulse valve, forms First air and Secondary Air, and filter bag is carried out
Filter bag dust is removed in reverse impact vibration, and ash-removal effect is good, safe and reliable to operation, effectively extend filter bag service life and
Improve the purification efficiency of filter bag.
