Background technology
Conventional ammonia low pressure recycle bucket only possesses vapor-liquid separation and storage liquid circulatory function, and lower liquid mouth connects ammonia pump, and ammonia pump entrance installs well strainer additional.Containing refrigeration oil from the liquefied ammonia that conventional ammonia low pressure recycle bucket flows out, even also containing solid sundries such as welding slags, be easy to be attached on screen pack, accumulate over a long period and be very easy to screen pack to block, now, ammonia pump entrance pipe drag losses sharply strengthens, and ammonia pump produces cavitation phenomenons, and long-term cavitation can cause ammonia pump impeller failure even to burn the motor of ammonia pump.Ammonia pump blocks up the damage phenomenon caused because filter is dirty commonplace, and the generation of this fault cannot be eradicated or avoid to the ammonia pump of supporting conventional ammonia low pressure recycle bucket.
Summary of the invention
The purpose of this utility model is to provide the ammonia low pressure recycle bucket carrying filtering function that a kind of structure is simple, medium is had to the phenomenon generations such as filter effect, the cleannes ensureing cooling medium liquefied ammonia, the middle filtrator blocking of minimizing cooling system and pump damage, overcomes the deficiencies in the prior art.
The ammonia low pressure recycle bucket carrying filtering function of the present utility model, comprise by left end socket, cylinder, the cylindrical shell of right end socket composition, cylindrical shell is provided with Liquid level assembly, throttling inlet, relief valve assembly, bleeding point, Pressure gauge, inlet, liquid barrier is provided with in inner barrel, the middle part of cylindrical shell and the bottom being positioned at cylinder is provided with sandwich-type cinder ladle, sandwich-type cinder ladle comprises outer tube and is positioned at the pipe inside outer tube, interlayer gap is formed between outer tube and interior pipe, the upper end of outer tube connects with described cylinder, the inner termination of interior pipe stretches in cylinder, the inner termination place of interior pipe is covered with anti-slag plate, the intracavity inter-connection of interlayer gap and cylinder, connect with liquid outlet after interior pipe external end head stretches out from the closed external end head place of outer tube, the side of outer tube is connected to the fuel outlet be connected with interlayer gap, the external end head of outer tube is connected to the sewage draining exit be connected with interlayer gap.
The described interior pipe inner termination length stretched into inside cylinder is 100 ~ 200mm.
For being welded and fixed between described anti-slag plate and the madial wall of cylinder.
Described liquid barrier is arranged on immediately below bleeding point, is welded and fixed with the madial wall of cylinder (3).
The ammonia low pressure recycle bucket carrying filtering function of the present utility model, liquid mouth under ammonia low pressure recycle bucket is designed to liquid shape of the mouth as one speaks formula under sandwich-type cinder ladle, low pressure recycle bucket possessed filter and store the function of the dirt such as refrigeration oil and welding slag, ensure that the liquefied ammonia flowing out ammonia low pressure recycle bucket has high cleannes, thoroughly improve the operating condition of supporting ammonia pump, essentially eliminate because entrance front filter blocks the ammonia pump damage fault caused.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model detailed description of the invention;
Fig. 2 be Fig. 1 depending on a left side look schematic diagram.
Detailed description of the invention
As shown in Figure 1, 2: cylindrical shell is made up of left end socket 1, cylinder 3, right end socket 9, the same with existing ammonia low pressure recycle bucket on cylindrical shell, Liquid level assembly 2 for controlling liquid level in bucket, throttling inlet 4, relief valve assembly 5, bleeding point 7, Pressure gauge 8, inlet 10 are installed equally, liquid barrier 6 is provided with in inner barrel, liquid barrier 6 is arranged on immediately below bleeding point 7, and liquid barrier 6 is welded and fixed with the madial wall of cylinder 3.
The middle part of cylindrical shell and the bottom being positioned at cylinder 3 is provided with sandwich-type cinder ladle 11, sandwich-type cinder ladle 11 comprises outer tube and is positioned at the pipe inside outer tube, namely the mutual coaxial package of bimetallic tube is arranged, interlayer gap is formed between outer tube and interior pipe, upper end and the cylinder 3 of outer tube are welded to each other, the inner termination of interior pipe stretches in cylinder 3, and the length stretched into is 100 ~ 200mm, is generally 150mm.The inner termination place of interior pipe is covered with anti-slag plate 12, for being welded and fixed between anti-slag plate 12 and the madial wall of cylinder 3.The function of anti-slag plate 12 prevents the impurity in cylindrical shell such as welding slag or other foreign material from entering the inner chamber of interior pipe.The intracavity inter-connection of interlayer gap and cylinder 3.Connect with liquid outlet 13 after interior pipe external end head stretches out from the closed external end head place of outer tube.The side of outer tube is connected to the fuel outlet 15 be connected with interlayer gap, and the external end head of outer tube is connected to the sewage draining exit 14 be connected with interlayer gap.
The general principle carrying the ammonia low pressure recycle bucket of filtering function of the present utility model: ammonia low-pressure steam liquid mixture flows in cylindrical shell through the inlet of throttling inlet 4 and connection evaporimeter respectively, most liquefied ammonia is isolated by gravitational settling and shock end socket inwall, remaining a small amount of liquefied ammonia is kept off back in staving by the liquid barrier 6 below bleeding point 7, ammonia is drawn back compressor through bleeding point 7, ammoniacal liquor to be stored in staving and through liquid outlet 13 flow into ammonia pump pressurized after be delivered to evaporimeter, brought into the thing such as refrigeration oil and welding slag in staving by ammonia, again because the density of refrigeration oil is greater than the density of liquefied ammonia and does not melt mutually, therefore refrigeration oil can be deposited in the bottom of ammonia low pressure recycle bucket under gravity, the solid sundries such as welding slag also landing to the bottom of bucket, the solid sundries such as refrigeration oil and welding slag only occupies the very little height of bottom of the barrel less because measuring, all clean from the liquefied ammonia more than a bit of distance in bottom, and the ammoniacal liquor flowing out staving is the liquefied ammonia of the clean area of distance more than bottom of the barrel 150mm, and be anti-slag plate 12 directly over liquid outlet 13, block the possibility that the solid sundries such as refrigeration oil or welding slag vertically falls into liquid outlet 13, sandwich-type cinder ladle is positioned at the bottom of cylinder, the solid sundries such as refrigeration oil and welding slag is assembled the most at last and is stored in the interlayer gap of cinder ladle.There is the advantage that structure is simple, medium is had to the phenomenon generations such as filter effect, the cleannes ensureing cooling medium liquefied ammonia, the middle filtrator blocking of minimizing cooling system and pump damage.
