Description
Technical field
The present invention relates to the technical field of the dirty water decontamination handles, particularly regenerating unit is washed in a kind of air water blowback for tubular type sintered membrane filter.
Background technology
Tubular type sintered membrane has that unit volume filter area is large, unit filter area filtering traffic is large, filtering accuracy is high (can reach 0.1 μm), stain resistance is strong, stiffness and strength is large, voltage endurance capability is strong, the features such as power of regeneration is strong are washed in blowback, is widely used in the dirty water decontamination handles of the industries such as chemical industry, food, medical medicine, biotechnology, environmental project or the aspect such as clarification filtration, solid-liquor separation of other liquid.
Preventing film from blocking, extend the service life of film, reducing processing cost is the target that film filter industry is pursued always.Because sintered pipes is rigidity, compressed air blowback can be utilized, not only the filter residue on tube wall can be blown off, by the particulate blowback in capillary micropore out, thus pulse cleaning can also be reached simultaneously.
In order to improve sintered pipes filter unit filter capacity, reduce the processing cost of unit volume solid-liquid treating capacity, manufacturing enterprise by hundreds of root even thousands of sintered pipes be loaded in a filter housings, form the device that a filter capacity is larger, there is cost low, take up an area little, the feature such as simple to operate.
But the shortcoming of this structure is that blowback air-flow is uneven, causes blowback not thorough, there is blowback dead angle.As time goes on, there is part film to lose filtration, thus reduce the filter capacity of filter.The blowback cleaning device of current this kind of filter blowback is washed chamber to be separated into several loculus, a loculus is washed by an independent air feed blowback of anti-blowpipe, but evenly can clean every root chimney filter when cannot ensure that blowback is washed, generally for and reach cleaning object, the distance by strengthening gas hole and film pore is only had to reduce the blowback pressure reduction of each film pore, the time that increase blowback is simultaneously washed and number of times, this had both caused the increase of air consumption to cause energy resource consumption large, also make just excessive because of blowback air flowing pressure to the film pipe of gas hole, increase the danger that chimney filter is left out.Due to the increase of gas hole and film pore distance, the volume in blowback chamber is increased, if blowback air tank volume does not increase, makes the average pressure in blowback chamber reduce on the contrary, thus reduce blowback effect on the whole.
As: the patent No. is that the Chinese patent of ZL200620001726.8 discloses a kind of accurate filter, its blowback is washed mouth and is located at blowback top of chamber, when blowback is washed, from blowback wash chimney filter stream pressure close to mouth and speed larger, produce larger impact and increase the danger that chimney filter is left out, then by air velocity and pressure, less to cause blowback to be washed not thorough for the chimney filter washing mouth away from blowback.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of air water blowback cleaning device for tubular type sintered membrane filter, can make every root chimney filter uniform stream, there is not blowback and wash dead angle, can reach the object that thorough blowback is washed by this device.
For solving the problems of the technologies described above, technical solution of the present invention is:
A kind of air water blowback cleaning device for tubular type sintered membrane filter, blowback in the housing of this filter is washed in chamber and is provided with at least one air distribution plate, this air distribution plate and the chimney filter connecting plate interval be arranged in described housing are arranged, and this air distribution plate has some qi-emitting holes, align in installing hole one_to_one corresponding in order to fixedly mount sintered membrane pipe of each qi-emitting hole and some on chimney filter connecting plate center.
The aperture of each qi-emitting hole of described air distribution plate is less than the aperture of the film pipe apopore that described chimney filter connecting plate is installed.
Described air distribution plate is provided with one, and the spacing of this air distribution plate and chimney filter connecting plate is not less than 4 times of the qi-emitting hole aperture on this air distribution plate.
Described air distribution plate is provided with more than one, and each air distribution plate and chimney filter connecting plate are arranged at interval successively; From chimney filter connecting plate to the air distribution plate farthest away from chimney filter connecting plate, the aperture in the hole on each plate reduces step by step; Further, from chimney filter connecting plate to the air distribution plate farthest away from chimney filter connecting plate, the spacing between two adjacent panels is not less than 4 times of the aperture in the hole on rear stage plate.
Described blowback is washed in chamber and is provided with blowback and washes air inlet, this blowback is washed air inlet place and is provided with a gas distribution pipe, this gas distribution pipe stretches into described blowback and washes inside, chamber, and this gas distribution pipe stretches in the radial tube wall that blowback washes inside, chamber has some radial holes, and axial inner end is plugging structure.
The axial inner end of described gas distribution pipe is welded on the air distribution plate of afterbody, to realize plugging structure.
Each radial hole on described gas distribution pipe distributes axisymmetricly along gas distribution tubular axis center.
After adopting such scheme, the present invention has following beneficial effect:
1. the present invention arranges and has the air distribution plate of qi-emitting hole, makes each qi-emitting hole just to a sintered membrane pipe, thus can play guiding function to counter purging gas stream, and solve blowback and wash uneven, blowback and wash halfway phenomenon, blowback is washed no longer exists dead angle.
2. after the present invention is provided with air distribution plate at different levels, from the installing hole chimney filter connecting plate to the qi-emitting hole on air distribution plate at different levels, aperture reduces step by step, thus the air velocity making blowback wash also reduces step by step, make the dynamic pressure of air-flow change static pressure into as far as possible, which reduce the impact of air-flow, reduce noise, reduce the impulsive force that film pipe bears simultaneously.
3. the present invention is provided with gas distribution pipe further, makes to enter blowback and washes air-flow in chamber from the transverse direction longitudinally changed into surrounding, thus air-flow can be made evenly to announce further, blowback is washed evenly.
4. the present invention can reduce the height that chamber is washed in blowback, alleviates complete machine weight, reduces production cost simultaneously.
In a word, test shows, evenly can clean every root sintered membrane pipe when structure blowback of the present invention is washed, anti-flushing times is short, saves air consumption, and blowback energy resource consumption can save 50-60%, and improves the service life of sintered membrane pipe.
