Description
Technical field
The invention belongs to technical field of environmental protection in chemical industry, be specifically related to deashing device and the online ash removal method of a kind of Waste Sulfuric Acid pyrolysis recycle device by utilizing waste heat boiler.
Background technology
All kinds of chemical plant installations of China, such as relating to sulfonation, alkylation, hydration hydrolysis, purify and the technique such as dehydration, annual the most all can a large amount of Waste Sulfuric Acid of by-product, wherein containing a large amount of organic impuritiess and inorganic salts in a big chunk Waste Sulfuric Acid, use conventional methods extremely difficult process, bring great environmental protection pressure to enterprise.
At present, process this kind of Waste Sulfuric Acid the most thoroughly, the technique of environmental protection be exactly Waste Sulfuric Acid pyrolysis recycle technique.In Waste Sulfuric Acid pyrolysis recycle technique, the flue-gas temperature that pyrolysis furnace is discharged is up to 1100 DEG C.Owing to containing substantial amounts of moisture and ash in flue gas, flue gas has to pass through washing, purifying before continuing operation after entering.Flue gas washing purifies and is necessary for first cooling down, waste heat boiler is undoubtedly optimum selection as chiller, is recycled by the high level heat in flue gas by waste heat boiler, produces middle pressure steam, not only save the energy, be also greatly reduced the operating cost of device.
Owing to the flue gas that pyrolysis furnace is discharged containing the SO of high concentration2、SO3、H2The components such as O, and carry more ash even liquid salt secretly so that the flue gas entering waste heat boiler has severe corrosive and tack, it is easy to causes boiler corrosion perforation and heat exchanger tube ash deposit and slag buildup, uses traditional waste heat boiler cannot meet the requirement of technique.
For the characteristic of Waste Sulfuric Acid pyrolysis recycle flue gas, applicant propose in patent application before a kind of can tolerate for a long time fume high-temperature corrosion again can be with the waste heat boiler of online ash removal salt discharge.
Summary of the invention
Owing to being entrained with substantial amounts of ash even fused salt in Waste Sulfuric Acid pyrolysis recycle flue gas, applicant proposes in patent application before and a kind of can solve, with the waste heat boiler of online ash removal, the frequent parking problem caused due to heat exchanger tube ash deposit and slag buildup.
Deashing device and online ash removal method that a kind of and above-mentioned waste heat boiler matches are the purpose of the present invention is to propose to.
Waste heat boiler online ash removal device of the present invention is achieved like this: the online ash removal device of Waste Sulfuric Acid pyrolysis recycle device by utilizing waste heat boiler, it is characterized in that it includes: wire brush, scraper, deashing bar, handle or reducing motor, deashing bar front end is sequentially provided with wire brush and scraper, and the rear end of deashing bar arranges handle or reducing motor.
Usually, described wire brush is demountable structure, and the external diameter of wire brush is not more than the internal diameter of exchanging pipe of boiler by waste, and the material of wire brush is carbon steel or steel alloy.
Described scraper is welding or demountable structure, and scraper is round tube shape structure, and there is sawtooth front end, and scraper external diameter is compared with the heat exchanger tube internal diameter of waste heat boiler to when young more than 5mm, and the material of scraper is carbon steel or steel alloy.
Described handle is welding or demountable structure, is made up of round steel or steel pipe, and the material of handle is carbon steel or steel alloy.
Described deashing bar is round steel or steel pipe is made, and the length of deashing bar meets scraper and stretches out the requirement of heat exchanger tube, and the material of deashing bar is carbon steel or steel alloy.
The present invention uses the online ash removal method of above-mentioned online ash removal device: when it is characterized in that online ash removal, first the sealing structure of waste heat boiler deashing pipe is unloaded, then exchanging pipe of boiler by waste is stretched in one end of deashing bar strip steel wire brush, rotating ash removal bar, by the scraper sawtooth of deashing bar front end, dust stratification is scraped from heat exchange tube wall, push forward simultaneously, until the front smoke box of waste heat boiler, being pushed away by the dust stratification scraped falls in front smoke box, discharge through boiler dust inlet, the most repeatedly, until the dust stratification in heat exchanger tube is cleaned out, finally that the deashing seal of tube is good, then repeat the above steps, until having managed all heat exchanger tubes.
Usually, the inventive method drives deashing bar to rotate by handle or reducing motor.
It should be noted that the heat exchanger tube simultaneously carrying out deashing operation can not be too many, the most once a piece heat exchanger tube of cleaning, in order to avoid too much cold air is sucked in boiler by deashing pipe, affect the composition of flue gas, and then affect the stability of device.Described clear up preferably no more than 10 heat exchanger tubes every time simultaneously.
The maximum feature of the present invention is efficient, convenient and safety and stability.
