Abstract
A kind of cleaning device for boiler tube inwall, comprise scraping nail, body, jet pipe, body two ends are conical, interlude is cylindrical, the inside of body arranges jet pipe, through jet orifice is had in jet pipe, the cylindrical segment of body buries number row scraping nail underground, often arrange scraping nail to distribute in the shape of a spiral on cylindrical surface, the utility model is put in heating furnace tube, huge discharge injection liquid stream in heating furnace tube, under the effect of jet pipe, before and after body, produce pressure differential promote its walking, during walking, scraping nail is to Jiao's on heating-furnace inside pipe wall, hard scale carries out scraping, scraping nail distributes in the shape of a spiral at cylindrical surface, rotation can be produced during walking, make all surface of heating-furnace inside pipe wall can by scraping, can reuse after liquid after cleaning flows through separation, there is not the problem of contaminated environment, therefore, the utility model cleaning performance is good, problems of the prior art can be overcome, there is significant economic benefit and social benefit.
Description
Technical field
The utility model belongs to the cleaning equipment of petroleum and petrochemical industry heating furnace tube, is a kind of cleaning device for boiler tube inwall.
Background technology
In petroleum and petrochemical industry system, the method for heating furnace tube inner wall washing is mainly contained burn, Chemical cleaning two kinds of methods.Burning method cleaning heating furnace tube is by alternately passing into steam and compressed air, makes the burning of of Jiao in boiler tube with the object reaching removing.The method has mechanical coke to burn, and can not be eliminated without mechanical coke dirt (salt and iron sulfide), when the method is burnt, coke particle is with very high velocity shock elbow, elbow is worn and torn and erosion, also can cause potential potential safety hazard, when burning, also have pollutant emission, cause environmental pollution.Chemical method cleaning heating furnace tube utilizes a large amount of water and cleaning agent, injects in boiler tube, make the dirt on cleaning agent dore furnace inside pipe wall, but this method can not remove hard Jiao on boiler tube inwall, the waste liquid produced also pollutes the environment, and does not reach environmental requirement, so be prohibited from using.
Summary of the invention
The purpose of this utility model is to provide a kind of cleaning device for boiler tube inwall, can clean, and can overcome above-mentioned Problems existing in petroleum and petrochemical industry system to heating-furnace inside pipe wall.
The purpose of this utility model is achieved in that and comprises scraping nail, body, jet pipe, body two ends are conical, interlude is cylindrical, the inside of body arranges jet pipe, through jet orifice is had in jet pipe, the cylindrical segment of body buries number row scraping nail underground, often arranges scraping nail and distributes in the shape of a spiral on cylindrical surface.
The length of body is 1.5 times of its external diameter.
The beneficial effects of the utility model are: put into by the utility model in heating furnace tube, huge discharge injection liquid stream in heating furnace tube, under the effect of jet pipe, before and after body, produce pressure differential promote its walking, during walking, scraping nail is to Jiao's on heating-furnace inside pipe wall, hard scale carries out scraping, scraping nail distributes in the shape of a spiral at cylindrical surface, rotation can be produced during walking, make all surface of heating-furnace inside pipe wall can by scraping, can reuse after liquid after cleaning flows through separation, there is not the problem of contaminated environment, in cleaning process, pressure differential is produced before and after jet pipe, its port of export at jet pipe is made to produce disturbance jet, make to be scraped Jiao's chipped away, hard scale suspends, accumulation can not be produced, pipeline jam accident can not be there is, therefore, the utility model cleaning performance is good, problems of the prior art can be overcome, there is significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As seen from Figure 1, embodiment of the present utility model comprises scraping nail 1, body 2, jet pipe 3, body 2 two ends are conical, interlude is cylindrical, the inside of body 2 arranges jet pipe 3, have through jet orifice in jet pipe 3, the cylindrical segment of body 2 buries number row scraping nail 1 underground, often arranges scraping nail 1 and distributes in the shape of a spiral on cylindrical surface.The length of body 2 is 1.5 times of its external diameter, ensures not produce pintle hook lock between body 2 and tube wall, can walk smoothly and rotate.
During heating-furnace inside pipe wall, the utility model is put into heating-furnace inside pipe wall, inwardly suppress, under the effect of jet pipe 3, before and after body 2, produce pressure differential promote it and walk and rotate, scraping is carried out to Jiao's on heating-furnace inside pipe wall, hard scale, scrape chip away Jiao's, hard scale washed away by liquid stream, makes heating-furnace be in control cleaning.
