The cleaning brush 8 is fiber hairbrush, and the scraper plate 9 is that the material with certain toughness and hardness is made.

In the present embodiment, spray bar and air jet pipe, several atomizers 5 and spray bar phase are provided in the oil gas jet pipe 3 Even, several air nozzles 4 are connected with air jet pipe；The oil gas feedway includes that high-pressure pump 28, oil pump 29 and three-way pipe connect Fitting 30, the high-pressure pump 28 are arranged in the upside of post-tensioning motor A22, and the gas outlet of high-pressure pump 28 is connected with appendix 31；The oil pump 29 is mounted on the bottom of flue ontology 1, and the oil outlet of oil pump 29 is connected with petroleum pipeline A32；The three-way pipe connects Fitting 30 is arranged at the top of retarder 24, and petroleum pipeline A32 and appendix 31 are respectively from the both sides port of threeway pipe connections 30 Stretch into, stretched out from Centronics port, petroleum pipeline A32 and appendix 31 pass through after threeway pipe connections 30 respectively with spray bar and jet Pipe is connected, and the Centronics port of the threeway pipe connections 30 is connected with the oil gas for being set in 31 outside petroleum pipeline A32 and appendix Delivery cannula 33, after the back clevis A windings on the oil-gas transportation casing 33 and retarder on output shaft 241 with oil gas jet pipe 3 are connected.By controlling oil gas feedway, in order to which cleaning ring carries out what jet, oil spout or jet were combined with oil spout Cleaning mode, it is easy to use, it is vdiverse in function.

In the present embodiment, the rear port of the flue ontology 1 connects cleaner 34（For existing cleaner）, flue The rear end bottom of ontology 1 offers the floss hole of an arc shape, and the lower end of the floss hole is connected with for collecting cigarette ash and clear The cigarette ash oil bucket 35 of clean oil is disposed with coarse strainer 36 and fie screen 37 in the cigarette ash oil bucket 35, such as Figure 16 from top to bottom Shown, scraper plate 9 scrapes the cigarette ash of 1 inner wall of flue ontology and cleansing oil to cigarette ash oil bucket 35, and coarse strainer 36 and fie screen 37 will Fluid after cleaning is detached with cigarette ash residue, and coarse strainer can filter the larger particle of grain size, and fie screen can filter grain size Smaller particle, filtered cleansing oil are stored in the bottom of cigarette ash oil bucket, and the one petroleum pipeline B38 of bottom of cigarette ash oil bucket 35 It is connected with the cleaning oil strainer 39 mounted on 1 bottom of flue ontology, cleans the delivery outlet of oil strainer 39 through a petroleum pipeline C40 is connected with the oil inlet of oil pump 29, i.e., filtered cleansing oil is delivered to further in cleaning oil strainer through petroleum pipeline B Filtering, the cleaned filtered fluid of filter are delivered in oil pump through petroleum pipeline C, are recycled.

The coarse strainer and fie screen and cigarette ash oil bucket are releasable connection.

Motor A, preceding drawing motor B, post-tensioning motor A and post-tensioning motor B is drawn to be mounted on by electric machine support 41 before described On the lateral wall of flue ontology；The high-pressure pump is arranged by a mounting bracket in the top of post-tensioning motor A.

In the present embodiment, it can be used for medium-sized, the coal-fired flue of large scale industry, flue diameter dimension is in 6m to 8m or more, mainly For cleaning the black dirt and dust stratification accumulated in flue.

Specific implementation process：When flue inner body wall dust stratification is more, cigarette ash can cover photoelectric sensor or part is covered Lid, photoelectric sensor send signal to main control unit, and Sheng Qu mechanisms driving cleaning ring moves from front to back, clear on rear side of cleaning ring Brush is first contacted with the dust stratification of flue inner body wall, plays the role of pineization dust stratification, at the same time, high-pressure pump can pass through jet Mouth is blown towards flue inner body wall, improves ash-removal effect；And the scraper plate on front side of cleaning ring in flue inner body wall being not easy to clear away Or the dust stratification blown down is scraped rearward.After multiple work, capacitance sensor still judges have part not remove with photoelectric sensor Dust stratification, at this time oil-gas change-over switch switch, oil pump action, and intermittent injection is carried out to flue inner body wall by atomizer Cleansing oil, cleansing oil can assist cleaning brush to clean dust stratification with scraper plate, and scraper plate may also function as the effect of frizing.Meanwhile in order to ensure Flue damages surface at high temperature under high pressure after its inner pipe wall will not be cleaned because of multiple physical, system is working cleaning ring is controlled When irregular oil spout, using cleansing oil to carry out automatically cleaning and surface maintenance to flue inner body wall and cleaning ring itself.When clear It sweeps ring after a period of use, moved by the small rail car started in each section of endless glide and packs up sliding block so that every section Sliding block on circular orbit is sequentially stacked, and because of being relatively large in diameter for flue, maintenance personnel can be convenient for each sliding block after packing up each sliding block On cleaning brush or scraper plate carry out concentrating cleaning or replacement, after maintenance, the small rail car on every section of circular orbit is along ring Shape track moves, and band movable slider is unfolded successively.

The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal Deng variation and modification, it should all belong to the covering scope of the utility model.
