Description

Technical Field

[0001] The utility model relates to the field of water tanks used for cleaning gas turbine blades, in particular to a water tank for gas turbine water washing. Background Technique

[0002] The LM6000 gas turbine is derived from the General Electric CF6-80C2 commercial aero engine. This engine first entered airline service in 1985 and has been widely used in wide-body airliners. Currently, more than 3,500 80C2 aero engines are in use or on order. Its efficient and reliable operating characteristics have been verified over the years. Based on the technical platform of this aero engine, the LM6000 series gas turbines have a maximum power generation capacity of over 50 MW. By enhancing modern design, improving the installation, maintenance characteristics and efficiency of the units, reliable technology is always provided to customers. Currently, the number of operating units worldwide is nearly 1,200. The LM6000 gas turbine power generation equipment can be used in simple cycle, combined cycle and cogeneration applications, meeting a wide range of customer needs. Its performance of rapid start-up within 10 minutes enables the LM6000 to not only undertake base load, but also be used in the modes of frequent start-stop, peak shaving or rapid response to grid dispatching. Through more than 15 years of application experience in the power generation field, from the cold Arctic slope in Alaska to the deserts in Nigeria and the coastal environment in Australia, the LM6000 has proven its perfect performance. Moreover, various inspections and replacement of hot components of the gas turbine can be carried out on site.

[0003] For an aeroderivative gas turbine, when taking in air, the air needs to be compressed first. The inhaled air is compressed, fuel is mixed in and ignited, and the high-temperature gas expands to provide power through the turbine. Subsequently, the exhaust gas is discharged into the atmosphere. The role of compressed air is that when the air is released, it will be accelerated and generate a force. Continuously replenishing new air can maintain this force. This force generated by air quality and acceleration can drive a load and the turbine. An electric motor is used to drive the compressor to maintain the force generated by air quality and acceleration to drive the load. Fuel burns between the compressor and the turbine, which can further accelerate the air, so a greater force is generated to drive the load. After the blades of the compressed air have been running for a long time, there will be dirt, and the dirt needs to be cleaned every once in a while. Usually, the cleaning work is carried out on the blades after the machine is shut down; the cleaning work is realized through a water tank. A cleaning agent is added to the water in the water tank, and after mixing, the water is pumped over through a pump and sprayed onto the blades. The dirt can be washed away by using the water with the cleaning agent and the high pressure of the water spray. Currently, at least the following problems still exist in this process:

[0004] 1. After rinsing the dirt on the blade surface with water containing a cleaning agent, in order to avoid the residue of the cleaning agent on the blade surface, it is also necessary to rinse the original blade with clean water once, so as to avoid the residue of the cleaning agent on the blade surface; in this process, adding a special water tank for clean water not only increases the cost, but also occupies the floor area and space, so the process of rinsing with clean water also uses the same water tank; however, at this time, clean water / pure water cannot be immediately filled into the water tank; instead, the water containing the cleaning agent in the water tank needs to be drained first, and the water tank needs to be cleaned. When the cleaning reaches the target, clean water / pure water can be put into the water tank; the problem in this process is that it is impossible to ensure that all the water containing the cleaning agent is drained completely, and the inside of the water tank needs to be washed repeatedly many times to wash out the cleaning agent component in the water tank; this increases the waste of water, as well as the labor cost and time consumption.

[0005] 2. When cleaning the inside of the water tank, there will be foam floating on the surface of the water tank, and the foam cannot be drained away in time with the water, which increases the cleaning time and wastes the cleaning water.

[0006] 3. At present, major industrial enterprises can only dilute the cleaning solution by a large number of repeated cycles of water replenishment and drainage. In this way, the cleaning degrees of different workers are also different. Especially for the inner wall of the water tank, it is very difficult to effectively clean, and the waste of water and labor costs is large. Summary of the Utility Model
