Abstract
The utility model discloses a connector for sealing and anticorrosion for seal and the anticorrosion in a carbonators water tank in nitrogen fertilizer industry. A plurality of tailor-made O-shaped rubber rings are superimposed to form the connector for sealing. The outer appearance of the connector for sealing is a corrugated pipe shape. Owing to aluminium and rubber has the anticorrosion for ammonia water and the rubber also has favorable elasticity, the seal between an aluminium cooling pipe and the plate of a carbon steel pipe, which enables the corrosion problem of the carbonators water tank to solve easily. A water tank which adopts the connector for sealing to make substantially makes use of the advantages of original equipment, such as simple structure, lower expenses, and good anticorrosion effect. The connector for sealing and anticorrosion can be used for the operating procedure of the normal pressure or pressurization of a carbonizer.
Description
The utility model belongs to the preserving and sealing coupling of carbonizing tower water tank in the nitrogen fertilizer industry.
Carbonizing tower is a key equipment in the carbonic hydroammonium production technology.The problem of its existence is the corrosion of the critical piece water tank of carbonizing tower.The structural type of water tank is a U type heat exchange of heat pipe, and it is made up of tube sheet, cooling tube, card, strut etc., and material is a carbon steel.In recent years, for solving the anticorrosion problem of carbonizing tower water tank, though lacquer is arranged; Cashew resin; Sodium sulfide; Spray epoxy; The aluminium-plated epoxy that is coated with; Anode (negative electrode) coating Combined Protection and making aluminum radiator aseptic technics such as (cooling tube replace the carbon steel weldless tube with aluminum pipe) occur, but are eliminated through the big portion of practice of factory.At present, because the anti-ammoniacal liquor corrosion of aluminum pipe, thermal conductivity is good, and the carbonization water tank of most medium and small chemical fertilizer factories adopts the cooling tube of aluminum to solve anticorrosion problem.But because of the aluminum pipe rigidity relatively poor, the general expand tube method that adopts connects between aluminum pipe and the tube sheet in addition, whole water tank weight reaches again about 100 kilograms, making and lifting by crane in the installation process, moves through several kinds, aluminum pipe and tube plate expanded-connecting place just often are difficult to guarantee to fit tightly, and fluctuation is arranged during the carbonizing tower routine operating pressure, can occur unavoidably running the ammonia phenomenon and influence using effect in water tank working process, aluminum pipe is squeezed because of expand tube again, during misoperation, often cause the local serious thinning phenomenon of pipe end.Simultaneously, because expand tube, aluminum pipe is extruded, and lattice is twisted, and makes aluminum tube surfaces be difficult to form fine and close alumina protective layer, causes the corrosion of aluminum pipe expanded joint section.
The purpose of this utility model is in order to make a kind of novel preserving and sealing coupling, to be difficult to fit tightly and anticorrosion, sealing problem between aluminum pipe in the solution carbonization water tank and carbon steel tube plate.
Technical characteristics of the present utility model is to adopt a kind of with between the special aluminium matter cooling tube and tube sheet of preserving and sealing coupling filling in the carbonizing tower water tank of rubber.Because all anti-ammoniacal liquor corrosion of aluminium and rubber, rubber has certain elasticity again, has guaranteed the excellent sealing between aluminum pipe and the tube sheet, has solved the etching problem of carbonizing tower water tank.This novel preserving and sealing coupling forms for several special O type rubber rings coincide, and outward appearance is a corrugated tube shape.The ripple that the inner ring of rubber ring is become with the outer ring when coinciding can misplace or be consistent, and its ripple number generally should be seen accompanying drawing 2 more than or equal to 2(); The rubber kind is common glue, and hardness (Shao Er A type) is between 65～75; Each fitting surface of sealed attachment part and tube sheet and cooling tube had the magnitude of interference of 0.3～0.8mm after the inside/outside diameter size of sealed attachment part was decided according to the gap between cooling tube and the tube sheet, should be guaranteed to assemble, to guarantee the excellent sealing between the three, in order to guarantee that aluminum pipe and sealed attachment part and tube sheet three fit tightly, other has pressing plate to be pressed on the bellows in addition.Pressing plate can be fixed with Bolt Connection method or welding process and tube sheet or strut.
Advantage of the present utility model is: simple for production, man-hours requirement only is 1/2nd of former expand tube method man-hour; Expense is cheap, and the material cost of the sealed attachment part of every water tank only is 1/20th of raw water box making and material cost; Convenient disassembly, tube sheet can repeatedly reuse, and the life-span prolongs more than 2～3 times than former expand tube method; Good seal performance is being guaranteed under the prerequisite of machining accuracy, needn't pressure testing, guarantee not leak.All applicable for carbonizing tower normal pressure or pressurized operation technology, be the most effective and reliable method that solves the corrosion of carbonizing tower water tank.
Accompanying drawing 1 is the structural representation of carbonizing tower water tank.Accompanying drawing 2 places the interior structure diagram (partial cutaway diagrammatic sketch) of carbonizing tower water tank for the preserving and sealing coupling.1 is aluminium matter cooling tube among the figure, and 2 is carbon steel tube plate, and 3 is the sealed attachment part, and 4 is pressing plate, and 5 is strut.
From accompanying drawing 2, find out: between aluminum pipe (1) and the tube sheet (2) sealed attachment part (3) is arranged.Because sealed attachment part (3) has certain magnitude of interference, guaranteed that aluminum pipe (1) and tube sheet (2) fit tightly, add top board (4) and be pressed on again on the sealed attachment part (3), guaranteed the sealing of aluminum pipe (1) and tube sheet (2), thereby solved the sealing and the anticorrosion problem of carbonizing tower water tank.
Example
Carbonizing tower water tank cooling tube bore is φ 25 * 2.5 o'clock: 1. the Kong Shangzai of former φ 25 bores φ 36.5 holes on the tube sheet, and the two becomes shoulder hole with former φ 25 holes; 2. sealed attachment part external diameter is φ 37.1, and ripple is several 3, and internal diameter is φ 23.4, and ripple is several 4, and height is 20; 3. the sealed attachment part is inserted in tube sheet φ 36.5 holes; 4. aluminum pipe inserts in the sealed attachment part; 5. settle pressing plate on the sealed attachment part; 6. pressing plate and tube sheet or strut are fixed.Press the carbonizing tower water tank that said process is made in certain small fertilizer plant, in 6 years of production practices operation, use condition is good.Do not find bad and etching problem to occur sealing because of the problem of sealed attachment part.
Claims (3)
1, a kind of novel preserving and sealing coupling that is used for nitrogen fertilizer industry carbonizing tower water tank.Sealed attachment part (3) places between the aluminium matter cooling tube (1) and tube sheet (2) of water tank, and is pressed on the sealed attachment part with pressing plate (4).The sealed attachment part (3) that is characterised in that of the present utility model forms for several special O type rubber rings coincide, and outward appearance is a corrugated tube shape.The ripple that the inner ring of rubber ring is become with the outer ring when coinciding can misplace or be consistent, and its ripple number generally should be more than or equal to 2; Sealed attachment part (3) inside/outside diameter size is decided according to the gap between cooling tube and tube sheet.It cooperates the fitting surface of back sealed attachment part and cooling tube and tube sheet that certain magnitude of interference is arranged, generally at 0.3～0.8mm.
