Description
Technical field
This utility model belongs to gas chamber safe handling and maintenance technology field, particularly relates to a kind of gas chamber leak source and repairs
Structure.
Background technology
Gas chamber is the device storing coal gas, the least to 250m3, arrive greatly 30000m3, be coal gas user (resident,
Process units) and the buffer unit of gas producing device (Gas-making Furnace), be equivalent to the effect of cistern.Generally by tank,
Bell jar, middle joint form, and bell jar and middle root section are according to the aerogenesis situation of aerogenesis apparatus and being automatically adjusted by gas situation of coal gas user
Relevant position in the sink carries out mating corresponding volume, plays self balancing effect, its run whether normal not
Only being directly connected to the continuous production of whole system, the personal safety with numerous Manufacturing Workers and the people ceases especially
Relevant.
Why gas chamber there will be leakage because first, coal gas is also referred to as semiwater gas, is by allowing coal gasification produce
, by some hydrogen sulfide of by-product, coal tar etc, these materials gas chambers to us in coal gasification course
Intercrystalline corrosion and electrochemical corrosion can be produced；The second, gas chamber is immersed in water throughout the year, and metal is endangered pole by wet environment
Greatly；3rd, the bell jar of gas chamber, middle joint are in jacking condition all the time along with the change of tolerance, easily produce exercise fatigue；
4th, the pressure that gas chamber is born is also among change along with the change of tolerance, and its wall is relatively thin, and alternate stress makes
It produces fatigue rupture.
There is leakage in gas chamber one end, it will the biggest harm occur.The first, waste resource and the energy, coal gas is a kind of
Resource, it should service the mankind, have leaked and be directly discharged to air exactly and suffer, be the biggest wasting of resources, simultaneously coal gas
Being coal obtains by consuming the energy, and leaking in air is also the waste of the energy；The second, the main component of coal gas
Being carbon monoxide, the harm of carbon monoxide is well-known, and the essence of carbon monoxide poisoning is exactly carbon monoxide poisoning, leaks out
The person is had great toxicity, if our workman is in containing in certain density coal gas environment for a long time, healthy
Will be by very macrolesion；3rd, containing certain density hydrogen sulfide etc. in coal gas, if it occur that leakage, to air,
The environment such as soil, water will produce the biggest pollution；4th, coal gas belongs to flammable and explosive substance, leaks out and easily causes
The extreme security incident such as burning, blast.
Gas chamber leakage is commonplace, the most usually takes such several method to repair: 1, after leakage
Electric welding carries out soldering, and soldering can be divided into again direct soldering and drain soldering.A, it is all metalwork due to gas chamber, pressure
The highest, crack is not that very big, leakage rate carries out soldering with regard to direct electric welding when being not a lot, b, crack very greatly, let out
When leakage quantity is bigger, direct soldering is the most relatively difficult, the most just takes drain soldering method, and a drain is done in drain soldering exactly
Soldering frock, first allows the coal gas leaked by this frock toward us predetermined place, direction discharge, treats the portion of this welding
The method of re-closed floss hole after the welding of position；2, bonding is repaired, and bonding is repaired and utilized healant and binding agent
The method that leakage position is repaired by adhesive action；3, mechanical clamp is repaired, and mechanical clamp is repaired and used machinery
The method that leakage position is clamped forcing leak-stopping by method by T-bolt, grip block, rubber.
Tradition leak source method for repairing and mending, the problem existed and defect: 1, electric welding soldering needs are got angry, there is great safety wind
Danger, the harshest to system component content requirement, oxygen content necessarily be in extremely low level, and wants on-line continuous to control,
Welding repair process must assure that gas chamber leakage point is in suitable height, needs total system the most in tension, coal
Gas holder local environment is moist, and welding worker exists the risk got an electric shock, additionally, electric welding temperature is up to 8000 DEG C, easily makes steel
Material generation Material degeneration, thus aggravate the damage of gas chamber, meanwhile, the weld seam of 8000 DEG C runs into the water inside gas chamber,
New stress will be produced, form the hidden danger again destroyed；Drain soldering also can form one on more smooth gas chamber surface
Fixed protrusion, if its size controls bad, or when gas chamber makes, technical size controls not in place, it is possible to
Obstacle gas chamber properly functioning；2, bonding is repaired the highest to the skill set requirements of operator, and operating time window is the narrowest,
Processing surface and require harshness, site environment is highly detrimental to again surface and processes, and the time adhered to after repairing is the shortest,
Effective also with regard to about one month.Particularly, the quality of materials such as healant is the most directly perceived, it is difficult to find quality of materials in advance
Problem.And quality of materials quality to repair after durability degree even success rate all it is critical that；3, mechanical clamp is mended
Needing by force breach relatively big (can put in T-bolt), limitation is relatively big, equally can be on more smooth gas chamber surface
Forming certain protrusion, if its size controls bad, or when gas chamber makes, technical size controls not in place, just
Likely obstacle gas chamber is properly functioning, simultaneously because the elasticity of rubber is not very big, gas chamber wall planarization again can not
Can repair and be difficult to reach perfect degree very well.
