Description
Technical field
The present invention relates to fluid purification technical fields, especially a kind of to dodge the clear membrane process of quick-fried method recoil and its device.
Background technique
In cleaner, bag filter is a kind of equipment being widely adopted.Since the frame mode of filter bag determines
This bag-type dust equipment can only and its low pressure under run, and running resistance rapidly increases.Running resistance determines
Dust pelletizing system energy consumption, filter efficiency and cleaning cycle.Once running resistance is excessively high, it will cause equipment work efficiency drops
It is low, cause dust collection capacity insufficient, also will affect the load of whole system.It is clear when carrying out very brief injection to filter bag using compressed air
When grey, deashing effect is weaker, and which define the sound development of this kind of equipment.Especially removed in the gentle box pulse of pulse
In dirt device, dust is attached to the outer surface of cloth bag.When dusty gas passes through deduster, dust is trapped in the appearance of filter bag
At this moment face carries out deashing, form gas tank and contend with the pressure inside filter bag, and recoil deashing is forced to cannot achieve.
Based on this, the present invention provides a kind of recoil clear membrane process and its devices of quick-fried method that dodge to be asked with solving above-mentioned technology
Topic.
Summary of the invention
The object of the invention is to solve problems of the prior art, provide it is a kind of dodge quick-fried method recoil clear membrane process and
Its device, the quick-fried method of the sudden strain of a muscle recoil clear membrane process and its device can by compressed gas, to the dust for being attached to membrane surface and
Dirt instantaneously dodged it is quick-fried remove contamination, reach the thorough cleaning to membrane, make membrane restore original state.
To achieve the above object, the clear membrane process of quick-fried method recoil and its device are dodged the invention proposes a kind of, membrane is carried out
Instantaneously dodge quick-fried cleaning.It due to dodging the quick-fried method clear membrane process that recoils is realized by device, dodges quick-fried method and recoil clear film device
Including filtration fraction and anti-cleaning dirt containing section composition.
The present invention adopts the following technical scheme that realization: device filtration fraction is the filtering appearance that can bear certain pressure
Device filters device filter membrane part in container, and filter membrane part is fixed in the device aperture of orifice plate, and orifice plate is placed in filtering vessel flange
Top is pressed with upper cover, and import is arranged an entirety is synthesized, in the side of filtering lower vessel portion in blending bolt,
Top is provided with outlet, and sewage draining exit is arranged in bottom.It is recoiled the dirt that clear film ejected to receive by filtration fraction, anti-cleaning is dirty
Object containing section uses dirt receiving container equally to receive and store dirt.Device dirt containing section is divided into Open architecture
And closed structure, Open architecture is the upper unit filtering membrane in waste rexeptacle, in the side of waste rexeptacle lower part
Import is set, sewage draining exit is set in waste rexeptacle bottom, is then communicated with atmosphere at the top of waste rexeptacle；Dirt containing section it is closed
Formula structure is cylinder body, piston structure, i.e., dress sets the piston that can be floated up and down in outer housing.When the surface of filtering portions membrane
It is covered by dirt, can make to increase by the Fluid pressure of membrane, when reaching set pressure, stored by gas tank
Gas can be inflated filtering container, and the gas filtered in container exists in a manner of pressure, when reaching set pressure
When, the sewage draining exit for filtering container bottom is instantaneously opened, and the gas moment that filtering container contents are stayed goes out sewage draining exit, is filtered in container
Instantaneous loss of pressure, the gas that space is stored in membrane while decompression are gone out inside-out by the filter membrane of membrane, make membrane
The dirt that outer surface is detained is carried out several times, by gas clean-up until membrane restores as before repeatedly.
When the filtering or the clear film medium that recoils are fluids, when fluid media (medium) is gaseous state, included fluid media (medium) is can
Combustion gas body, inert gas, air, steam or other gases；When fluid media (medium) is liquid, included fluid media (medium) is water, oil
Or sewage.
The filtering case or the shell of open waste accommodation device and closed waste accommodation device be not using
Become rusty steel making.
The shell for filtering case or open waste accommodation device and closed waste accommodation device, using stainless steel
Manufacture.
The clear membrane process of the quick-fried method recoil of above-mentioned sudden strain of a muscle and its apparatus structure are simple, and use cost is low, takes up little area, and low energy consumption, behaviour
Facilitate.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
