Description
Technical field
The invention belongs to gas chamber safe handling and maintenance technology field, particularly relate to a kind of gas chamber leak source and repair structure and leak source method for repairing and mending thereof.
Background technology
Gas chamber is the device storing coal gas, generally little of 250m3, arrive greatly 30000m3, it is the buffer unit of coal gas user (resident, process units) and gas producing device (Gas-making Furnace), is equivalent to the effect of cistern. Generally it is made up of tank, bell jar, middle joint, bell jar and middle root section are automatically adjusted relevant position in the sink by gas situation carry out mating corresponding volume according to the aerogenesis situation of aerogenesis apparatus and coal gas user'ss, play self balancing effect, the whether normal continuous production being not only directly connected to whole system of its operation, closely bound up with the personal safety of numerous Manufacturing Workers and the people especially.
Why gas chamber there will be leakage, because the first, coal gas is also referred to as semiwater gas, by allowing coal gasification produce, by some hydrogen sulfide of by-product, coal tar etc in coal gasification course, our gas chamber can produce intercrystalline corrosion and electrochemical corrosion by these materials; The second, gas chamber is immersed in water throughout the year, and wet environment is very harmful to metal; 3rd, the bell jar of gas chamber, middle joint are in jacking condition all the time along with the change of tolerance, it is easy to produce exercise fatigue; 4th, the pressure that gas chamber bears is also among change along with the change of tolerance, and its wall is relatively thin, and alternate stress makes it produce fatigue rupture.
There is leakage in gas chamber one end, it will very big harm occur. The first, waste resource and the energy, coal gas is a kind of resource, it should service the mankind, and have leaked is exactly be directly discharged to air suffer, and is the very big wasting of resources, and coal gas is that coal obtains by consuming the energy simultaneously, and leaking in air is also the waste of the energy; The second, the main component of coal gas is carbon monoxide, the harm of carbon monoxide is well-known, the essence of carbon monoxide poisoning is exactly carbon monoxide poisoning, leak out and the person is had great toxicity, if our workman is in for a long time containing in certain density coal gas environment, health will be subject to very macrolesion;3rd, containing certain density hydrogen sulfide etc. in coal gas, if it occur that leakage, the environment such as air, soil, water will be produced very big pollution; 4th, coal gas belongs to flammable and explosive substance, leaks out and very easily causes the extreme security incident such as burning, blast.
Gas chamber leakage is commonplace, is usually traditionally and takes such several method to repair: 1, electric welding carries out soldering after leakage, and soldering can be divided into again direct soldering and drain soldering. A, it is all metalwork due to gas chamber, pressure is not high yet, crack is not as greatly, leakage rate neither much time soldering is carried out with regard to direct electric welding, when b, crack are very big, leakage rate is bigger, direct soldering is just relatively difficult, at this moment just takes drain soldering method, and a drain soldering frock is done in drain soldering exactly, first allow the coal gas of leakage by this frock toward our predetermined place, direction discharge, treat the method for re-closed floss hole after the position welding of this welding; 2, bonding is repaired, and bonding repairs the method being exactly to utilize the adhesive action of healant and binding agent that leakage position is repaired; 3, mechanical clamp is repaired, and mechanical clamp repairs the method that leakage position is clamped forcing leak-stopping by the method adopting machinery exactly by T-bolt, grip block, rubber.
Tradition leak source method for repairing and mending, Problems existing and defect: 1, electric welding soldering needs to get angry, there is great security risk, system component content requirement is extremely harsh, oxygen content necessarily be in extremely low level, and want on-line continuous to control, welding repair process must assure that gas chamber leakage point is in suitable height, need total system in tension for a long time, gas chamber local environment is moist, there is the risk got an electric shock in welding worker, in addition, electric welding temperature is up to 8000 DEG C, very easily make steel generation Material degeneration, thus aggravating the damage of gas chamber, simultaneously, 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 certain protrusion on more smooth gas chamber surface, 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 skill set requirements of operator is high especially, and operating time window is very narrow, and surface treatment is required harshness, and site environment is highly detrimental to again surface treatment, and the time adhered to after repairing is often shorter, effective also with regard to about one month. especially, the quality of materials such as healant is not directly perceived, it is difficult to find quality of materials problem in advance. and quality of materials quality to repair after durability degree or even success rate all it is critical that, 3, mechanical clamp reinforcement needs breach relatively big (can put in T-bolt), limitation is bigger, certain protrusion can be formed equally on more smooth gas chamber surface, 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, simultaneously because the elasticity of rubber is not as big, gas chamber wall planarization very well, can not be repaired and be difficult to reach perfect degree again.
