On-line monitoring device for fume gas turbine moving blade scaling

Abstract

The invention discloses an on-line monitoring device for fume gas turbine moving blade scaling. The on-line monitoring device comprises a sampling tube (5), wherein a handle (6) is mounted at one end of the sampling tube (5); a packing tube (8) match with the sampling tube (5) in a sleeving manner is arranged at the other end of the sampling tube (5); a pressing cover (4) matched with the packing tube (8) in a covering manner is mounted at one end of the packing tube (8); a first flange disc (2) which is capable of being abutted with a fume gas turbine flue is mounted at the other end of the packing tube (8); a sampling head (1) is mounted at an end surface, opposite to the handle (6), of the sampling tube (5). The on-line monitoring device is simple in sampling and convenient to use, daily sampling steps are greatly simplified, the overall working efficiency is improved, device operation conditions can be adjusted in time, and a scaling phenomenon of a catalyst inside a fume gas turbine can be retarded or eliminated, therefore, long-term safe operation of the fume gas turbine can be achieved.

Description

technical field [0001] The invention relates to a device for on-line monitoring of scale fouling of a flue gas turbine moving blade in a catalytic cracking device in the petroleum refining industry. Background technique [0002] The dust contained in the flue gas entering the flue gas turbine in the catalytic cracking unit of the petroleum refining industry will cause huge damage to the flue gas turbine and seriously reduce its service life. The smoke machine is an important equipment in the catalytic cracking energy recovery system. Its safe and stable operation can not only bring huge economic benefits, but also is related to the smooth operation of the regenerator and the entire catalytic cracking unit. Therefore, it is important to ensure the normal and stable operation of the flue gas turbine. Significance. After the flue gas turbine starts running for a period of time, fouling of catalyst fine powder will occur on the stator blades, shrouds and moving blades. Scaling...

Problems solved by technology

The fouling of the smoke rotor blades will have a great impact on the safe and smooth operation of the smoke machine

A large amount of flue gas dust in the flue adheres to the flue and blades of the flue gas machine, and this distribution is often uneven, which will directly affect the dynamic balance of the rotor

In particular, the deposition and sintering of dust increases the weight of the blade, and the coke attached to a certain part of the blade is thrown off due to centrifugal force, which seriously damages the dynamic balance of the rotor and aggravates the vibration of the hood. In severe cases, the hood will Forced to shut down, thereby increasing the overall energy consumption level of the installation
