Application of steam traps in pharmaceutical plant steam systems
2022-11-26 11:08:56
Steam is one of the important energy sources for pharmaceutical companies. The heating, concentration, drying and heat exchange in production, including air conditioning and heating, use steam, and steam will change due to temperature changes during use. Condensed water, the condensed water produced must be discharged in time. Otherwise, the condensed water will accumulate in the equipment, which will greatly affect the efficiency of the heat transfer process, increase the possibility of generating water hammer, and even the heating process cannot be carried out. The condensate generated during the heating process needs to be discharged through the trap. A steam trap is actually an automatic valve. When it has condensed water, it automatically opens to discharge condensate, air and carbon dioxide gas and block the steam. Discharge, which requires the steam trap to be able to work stably for a long time, to minimize failure. The performance of steam traps is critical to the proper operation of the steam system.
It turns out that the steam trap installed by the pharmaceutical company using steam equipment is not good, often bad, and the condensed water can not be discharged in time to affect normal production. There is no way to open the bypass and the straight row. The result of the straight row is that the water is steamed together. Waste is imaginable, and the factory is braving white steam everywhere, which also affects the factory appearance.
Since 2010, the plant has begun to address this issue. Through a large number of investigations, they selected four steam traps at home and abroad. After a period of trial and comparison, Zui decided to use the series of traps of Rick Valve Suzhou Co., Ltd. First used on the distillation column system. The distillation tower uses a large amount of steam. The original steam trap is often bad, and it is often changed. Sometimes it is too late to change. It has to open the bypass, and even the water and steam are discharged together, which not only wastes a lot of steam, but also easily burns people. Our Rick technicians and the plant worked together to study not only to solve the problem of hydrophobicity, but also to recycle the condensate, so they used the Rick FT14-1.5 float trap, which is suitable for load change. For large occasions, it has good air discharge performance. The trap is used to pass the collected condensed water through the spiral plate heat exchanger to preheat the previous materials, which saves a part of the steam. This trap is used in three sets of rectification equipment, saving annually. More than 5,000 tons of steam, equivalent to RMB 315,000 (according to the current price), recovered the investment in more than a month.
With the above experience, the plant has replaced some of the main steam equipment, twin towers, steam packs and air conditioners with Rick's steam traps in a few years. The drainage and steam blocking effects are very good and the failure rate is very low.
By using a few points to summarize the correct use of the trap:
The selection of the trap of the trap is very important. It is not as simple as selecting the diameter of the trap according to the diameter of the pipe. If it is not selected, the effect of the trap will not be achieved.
First of all, the type of trap is different, the working principle is different, and the applicable conditions are different. It has: float type, inverted bucket type, thermodynamic type, thermostatic type, etc., so when selecting a trap, the following should be considered factor:
1. Application occasions 2. Connection method 3.zui big zui small load 4. Steam temperature 5. Equipment type 6. Whether with temperature control 7. Steam system pressure 8. Whether condensate is recovered 9. Pressure difference 10. Material 11 The lifting height behind the trap 12. Back pressure 13. Whether to install the emptying device 14. Safety factor 15. The ambient temperature seems complicated above, in fact, the main thing is to look at the specific application, the above various forms of steam trap working principle Different, adapted applications are also different. Therefore, it is first necessary to select a suitable type of trap according to the characteristics of the process drainage. In fact, consider factors such as pressure and displacement. Otherwise, the cart is upside down, even if the drain capacity of the trap can meet the requirements, it may not guarantee the normal drainage of the equipment.
Installation and Maintenance of Steam Traps Proper installation and maintenance is extremely important to ensure proper operation and longevity of the trap. In fact, this is not difficult, just follow the installation instructions and maintenance instructions provided by the manufacturer. For floating ball and inverted bucket traps, since they rely on the floating ball or the bucket to move up and down, care must be taken during installation. The floating mechanism should be moved up and down without error.
In short, the selection of steam traps with good performance and good quality is the guarantee for the normal production of steam equipment, and also the guarantee of product quality. In addition, it is energy saving. We roughly calculated it. Due to the use of good quality steam traps, we reduce the leakage of steam by about 15,678 tons per year, and the total amount of 63,072 tons in four years, at 60 yuan/ton, saving a total of 3.78 million yuan. many. In addition, there is also nearly 10,000 tons of steam saved each year by condensate recovery. Saved a lot of energy and money for the plant.
