Description
Technical field
The utility model relates to a kind of outer surface cleaning device of outside filtering type gas filter tube.
Background technology
Outside filtering type gas filter tube (relies on the outer wall of screen pipe as filtering surface, other end opening is closed in screen pipe one end, gas to be filtered, from the lateral inner chamber infiltration of screen pipe, finally flows out from openend) be the filter element that gas filtration field, especially high temperature air filtration field are commonly used the most.At present, in high temperature air filtration what use outside filtering type gas filter tube to adopt is the screen pipe that sintering diamond bit or sintered ceramic porous material are formed.Due to reasons such as the Industrial Stoves working of a furnace temperature fluctuations of originating as high-temperature gas to be filtered, the dust easily fouling sometimes of screen pipe surface attachment, and on filter itself with screen pipe back-blowing dust removing device be difficult to effectively remove these dirty blocks.In addition, in screen pipe use procedure, some tiny dust granules can pierce in screen pipe hole, thus cause plug-hole.Back-blowing dust removing device still cannot effectively solve plug-hole problem.Chemical cleaning mode can only be relied at present to carry out cleaning and regeneration to plug-hole screen pipe, but this mode can make reduce the service life of screen pipe.
Utility model content
First the utility model will provide a kind of clean method and equipment of outside filtering type gas filter tube, effectively improves tiny dust granule and pierces the technical problem causing plug-hole in screen pipe hole; The outer surface cleaning device of the outside filtering type gas filter tube that secondly the utility model also will provide a kind of result of use desirable.
The clean method of outside filtering type gas filter tube of the present utility model, comprises and to be mounted to by screen pipe on a screen pipe hole deashing blowing device and to use the operation that this blowing device processes screen pipe, described blowing device comprises screen pipe rotary support system, take and turn device, intermediate transmission mechanism, motor, telescopic injection tube and high-pressure air source, described screen pipe is arranged on screen pipe rotary support and fastens and the blind end of this screen pipe turns device and is connected with taking, take and turn device and be connected with motor by intermediate transmission mechanism, telescopic injection tube enters screen pipe inner chamber from the openend of screen pipe and goes directly at the bottom of pipe, the outer end of telescopic injection tube is connected with high-pressure air source, the pipe shaft of telescopic injection tube is provided with winding-up mouth, taking, to turn the pressure ejected from described winding-up mouth under device drives screen pipe to rotate be the whole medial surface that the gases at high pressure of 0.2 ~ 1.2MPa cover screen pipe, it is more than 18 revs/min that described screen pipe rotating speed controls, the continuous winding-up time of telescopic injection tube remains more than 10 seconds.
In said method, because described screen pipe rotating speed is more than 18 revs/min, the continuous winding-up time of simultaneous retractable formula injection tube is more than 10 seconds, namely in the one-time continuous winding-up process of telescopic injection tube, screen pipe at least have rotated 3 turns, this means certain same area at least 3 winding-up mouths by correspondence of screen pipe medial surface.And at present on filter itself with back-blowing dust removing device, adopting pulse dust cleaning mode, is about 0.2 second for avoiding impacting each blowback duration settings to system pressure, blowback frequency general hundreds of second.Visible, the utility model mesohigh gas acts on time of screen pipe, frequency and current back-blowing dust removing device and there is very large difference.In addition the medial surface that mouth of jetting in the utility model presses close to screen pipe carries out jetting and the factor such as blowing gas pressure setting, tiny dust granule in screen pipe hole can effectively blow out by the clean method of above-mentioned outside filtering type gas filter tube of the present utility model from screen pipe hole, improves plug-hole problem.
In said method, concrete, the preferred set-up mode of the one as described winding-up mouth, the pipe shaft of described telescopic injection tube is provided with at least two row's winding-up mouths, and each arranges winding-up mouth by multiple along the spaced winding-up mouth composition of telescopic injection tube central axis; Wherein row's winding-up mouth and another to arrange mouth of jetting be interlaced arrangement.Such winding-up mouth arrangement design, the gases at high pressure gas of winding-up can either be made evenly the whole medial surface acting on screen pipe, and deashing treatment effeciency can be improved.
In addition, the force value ejecting gases at high pressure from described winding-up mouth can more preferably 0.3 ~ 0.8MPa, then is preferably 0.4 ~ 0.6MPa; Screen pipe rotating speed controls can preferably control further to be 20 ~ 30 revs/min; The continuous winding-up time of telescopic injection tube can preferably remain 15 ~ 20 seconds further.Well can not only remove the fine dusts in screen pipe hole like this, and operating efficiency is high, minimum to the mechanical wounding of screen pipe.
When screen pipe surface attachment has the dust of not easy-clear or dirty block (filter cake), in order to prevent screen pipe surface attachments to the fine dusts in screen pipe hole being blown out the obstruction caused, said method also further comprise screen pipe is mounted to described screen pipe hole deashing blowing device before first this screen pipe to be mounted on a screen pipe outer surface cleaning device and to use the operation that this cleaning device processes screen pipe; Described outer surface cleaning device comprises screen pipe braced system, linear reciprocating mechanism and the screen pipe collar, described screen pipe to be arranged in screen pipe braced system and to parallel with the direction of motion of the slide block carrying out straight reciprocating motion in linear reciprocating mechanism, screen pipe cover ring set is as screen pipe is connected with described slide block by intermediate connector, and the inner side of the screen pipe collar is provided with the wire-cup brush with screen pipe exterior surface.Moved back and forth at screen pipe outer surface by wire-cup brush, the obstinate attachment on screen pipe outer surface can be removed, thus be conducive to using described blowing device to process screen pipe.
For the cleaning equipment of the outside filtering type gas filter tube of the utility model said method, comprise screen pipe hole deashing blowing device, described blowing device comprises screen pipe rotary support system, take and turn device, intermediate transmission mechanism, motor, telescopic injection tube and high-pressure air source, screen pipe is arranged on screen pipe rotary support and fastens and the blind end of this screen pipe turns device and is connected with taking, take and turn device and be connected with motor by intermediate transmission mechanism, telescopic injection tube enters screen pipe inner chamber from the openend of screen pipe and goes directly at the bottom of pipe, the outer end of telescopic injection tube is connected with high-pressure air source, the pipe shaft of telescopic injection tube is provided with winding-up mouth, turn the whole medial surface that the gases at high pressure ejected from described winding-up mouth when device drives screen pipe to rotate cover screen pipe taking.
The outer surface cleaning device of outside filtering type gas filter tube of the present utility model, comprise screen pipe braced system, linear reciprocating mechanism and the screen pipe collar, described screen pipe to be arranged in screen pipe braced system and to parallel with the direction of motion of the slide block carrying out straight reciprocating motion in linear reciprocating mechanism, screen pipe cover ring set is as screen pipe is connected with described slide block by intermediate connector, and the inner side of the screen pipe collar is provided with the wire-cup brush with screen pipe exterior surface.This screen pipe outer surface cleaning device is moved back and forth at screen pipe outer surface by wire-cup brush, can remove the obstinate attachment on screen pipe outer surface.
