Description
Technical field
It the utility model is related to cleaning device, more particularly to a kind of device for cleaning dirt in heating furnace tube.
Background technology
Tubular heater is the main firing equipment in refinery, and one of main energy consumption equipment, almost take part in oil
All kinds of technical process are processed, determine product quality and energy consumption of whole oil plant or device etc..It is a large amount of due to containing in oil product
Organic matter, including alkanes, cycloalkane, aromatic hydrocarbons and its derivative are easily heated that the reaction generation such as cracking, synthesis occurs
Macromolecular compound, cause oil viscosity to increase, coking can occur in the boiler tube inwall of tubular heater.Particularly heavy oil due to
The easy green coke material containing macromoleculars such as colloid, asphalitines is more, and coking is easier in heating.And coking, meeting occur for boiler tube inwall
Cause to have a strong impact on below：
1. heat transfer efficiency reduces, increase energy consumption.
2. heat transfer efficiency is low, oil product temperature can not reach technological requirement, reduce finished product quality.
3. tube skin temperature rises, because the thermal conductivity ratio steel pipe of coking layer is much smaller, there is the place of coking,
Local thermal resistance increase, boiler tube radial symmetry gradient is larger, and in the most thick place of coking layer, local thermal resistance increase, boiler tube is radially warm
Spend gradient and become big, in the most thick place of coking layer, cause tube skin focus occur, influence the boiler tube life-span.
4. the pressure loss increase of boiler tube, coking phenomenon seriously even block boiler tube.
5. if steel tube surface is relatively rough（Such as spun pipe）, with regard to easy carburizing, deteriorate steel strength, sometimes
Boiler tube CRACKING ACCIDENT can occur.
For these reasons, oil plant is serious to coking, and the tubular heater for influenceing normally to produce must be safeguarded, clearly
Coke and dirt in prepurging pipe, ensure the heat transfer efficiency of boiler tube, improve finished product quality, and ensure production safety.At present,
Snaking method in heating furnace tube mainly has：
1. high-temperature vapour-air decoking method：Traditional decoking, toward boiler tube in be passed through high-temperature steam and air, fire
Burn the coke in heating pipe.This method has to set the burnt related facility of combustion, and temperature change is big in burning process,
Corrosion/damage is produced to boiler tube, easily blocked up when coking situation is serious, the dirt such as salt crust can't be eliminated.
2. mechanical decoking：The hydraulic pressure that 0.5-4Mpa pressure is produced by high-pressure hydraulic pump will be as decoking instrument coke cleaning ball
（pig）It is pushed into the combustion flue of coking and carries out back and forth movement, utilizes the subsidiary metallic projections of coke cleaning ball surface（Screw）With pipeline
Inwall does mechanical friction, coke button, dirt and the scale crust scraped clean that will be attached on combustion flue inwall.The Jiao Zizai water wiped off
Take it out boiler tube and collect in bucket.This method has certain damage to boiler tube inwall（Scratch）；Screw on coke cleaning ball
Come off, do not clear up the plugging phenomenon that can be caused in production process；Coke-removing procedure misoperation, can cause coke cleaning ball be stuck in pipe or
Elbow, to carry out pipe cutting processing.
3. chemical reagent ablution：To be cleaned using soda acid chemical reagent, soda acid can corrode boiler tube in cleaning process, because
Special furnace tube material is 347H compo pipes, and pole capacity is produced such as caustic embrittlement, polythionic acid corrosion equivalent risk.
