Abstract
The utility model discloses an air water back blowing washing device for a tube-type sintered membrane filter. One or more cloth air plates are arranged in a back blowing washing cavity in a housing of a filter, and arranged at an interval with a filter pipe connecting plate mounted in the housing; a plurality of cloth air holes are formed in the cloth air plates, and in one-to-one correspondence and center justification with a plurality of mounting holes used for fixedly mounting sintered membranous pipes and formed in the filter pipe connecting plate. The additionally arranged cloth air plates can perform guiding function to back blowing airflow; the phenomenon that back blowing washing is not even and thorough is settled; dead angles of back blowing washing no longer exist.
Description
Technical field
The utility model relates to the technical field of the dirty water decontamination handles, and particularly regenerating unit is washed in a kind of air water blowback for tubular type sintered membrane filter.
Background technology
Tubular type sintered membrane have that unit volume filter area is large, unit filter area filtering traffic is large, filtering accuracy is high (can reach 0.1 μ m), 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 industry or the aspects such as clarification filtration, liquid-solid separation of other liquid such as chemical industry, food, medical medicine, biotechnology, environmental project.
Prevent that film from stopping up, extending the service life of film, reducing processing cost is the target that film filter industry is pursued always.Because sintered pipes is rigidity, can utilize compressed air blowback, not only the filter residue on tube wall can be blown off, simultaneously can also be by the particulate blowback in capillary micropore out, thus reach pulse cleaning.
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 a device that filter capacity is larger, there is cost low, take up an area the features such as little, simple to operate.
But the shortcoming of this structure is that blowback air-flow is inhomogeneous, cause blowback not thorough, there is blowback dead angle.As time goes on, there is part film to lose filtration, thereby reduce the filter capacity of filter.The blowback cleaning device of this class filter is blowback to be washed to chamber be separated into several loculuses at present, a loculus is washed by an independent air feed blowback of anti-blowpipe, but cannot guarantee when blowback is washed evenly to clean every chimney filter, conventionally in order to reach cleaning object, only has the blowback pressure reduction that reduces each film pore by the distance of increasing gas hole and film pore, increase time and number of times that blowback is washed simultaneously, this had both caused the increase of air consumption to cause energy resource consumption large, also just make the film pipe of gas hole, because blowback air flowing pressure is excessive, to increase the omitted danger of chimney filter.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, make on the contrary the average pressure in blowback chamber reduce, thereby reduced on the whole blowback effect.
As: the Chinese patent that the patent No. is 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, chimney filter stream pressure and speed close to washing mouthful from blowback are larger, produce larger impact and increase the omitted danger of chimney filter, by air velocity and pressure, less to cause blowback to be washed not thorough for the chimney filter of washing mouthful away from blowback.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of air water blowback cleaning device for tubular type sintered membrane filter, can make every chimney filter air-flow even by this device, does not exist blowback to wash dead angle, can reach the object that thorough blowback is washed.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of air water blowback cleaning device for tubular type sintered membrane filter, blowback in the housing of this filter is washed and in chamber, is provided with at least one air distribution plate, this air distribution plate arranges with the chimney filter connecting plate interval being arranged in described housing, and on this air distribution plate, have some qi-emitting holes, each qi-emitting hole and some installing hole corresponding and center-aligned one by one in order to fixedly mount sintered membrane pipe on chimney filter connecting plate.
The aperture of the film pipe apopore of installing on chimney filter connecting plate described in the aperture ratio of each qi-emitting hole of described air distribution plate is little.
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 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 the interval setting successively of chimney filter connecting plate; From chimney filter connecting plate to the air distribution plate away from chimney filter connecting plate, the aperture in the hole on each plate reduces step by step; And, from chimney filter connecting plate to the air distribution plate away from chimney filter connecting plate, 4 times of the aperture in the hole after the spacing between two adjacent panel is not less than on a step.
Described blowback is washed and in chamber, is provided with blowback and washes air inlet, this blowback is washed air inlet place a gas distribution pipe is installed, this gas distribution pipe stretches into described blowback and washes inside, chamber, and this gas distribution pipe stretches in blowback and wash the radially tube wall of inside, chamber and have some radial holes, and axial inner ends portion is plugging structure.
The axial inner ends portion 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.
Adopt after such scheme, the utlity model has following beneficial effect:
1. the utility model setting has the air distribution plate of qi-emitting hole, makes each qi-emitting hole just to a sintered membrane pipe, thereby can play guiding function to counter purging gas stream, and has solved blowback and has washed inhomogeneous, blowback and wash halfway phenomenon, and blowback is washed and no longer had dead angle.
2. after the utility model is provided with air distribution plates at different levels, installing hole from chimney filter connecting plate is to the qi-emitting hole on air distribution plates at different levels, aperture reduces step by step, thereby the air velocity that blowback is washed is also reduced step by step, make the dynamic pressure of air-flow change static pressure into as far as possible, reduce like this impact of air-flow, reduced noise, reduced the impulsive force that film pipe bears simultaneously.
3. the utility model is further provided with gas distribution pipe, make to enter blowback wash air-flow in chamber from longitudinally change into surrounding laterally, thereby can make air-flow further evenly announce, blowback is washed more even.
4. the utility model can reduce blowback and wash the height in chamber, has alleviated complete machine weight, has reduced production cost simultaneously.
In a word, test shows, when structure blowback described in the utility model is washed, can evenly clean every sintered membrane pipe, and it is short that the time is washed in blowback, saved air consumption, and blowback energy resource consumption can be saved 50-60%, and has improved the service life of sintered membrane pipe.
