Description
Technical Field
The present disclosure relates to gas turbines, and particularly to an ion waterfall purification apparatus and a gas turbine air intake system.
Background
The gas turbine is an internal combustion type power machine which takes continuously flowing gas as a working medium to drive an impeller to rotate at a high speed and converts the energy of fuel into useful work, and is a rotary impeller type heat engine. And the function of the gas turbine inlet air filtering system is as follows: the pollutants in the air, such as dust, particles, salt, water drops and the like, are filtered, so that clean air enters the gas turbine from the air inlet system, and the safe and reliable operation of the gas turbine generator set is ensured. If the filtering quality of the filtering system is not good, blockage can occur, so that the air inflow of the gas turbine can be reduced, and the output power and the heat efficiency of the gas turbine generator set can be reduced. If the filtering capability of the filtering system is poor (weak), dust or particles in the air can enter the gas turbine, so that the blades of the gas compressor are polluted, the power consumption of the unit operation is increased, the output power of the gas turbine generator set is reduced, the washing times of the blades of the gas compressor are increased, and the power generation time of the gas turbine generator set is influenced. In addition, particles such as dust in the intake air can cause impact damage to compressor blades of the gas turbine, and experiments show that particles with the particle size of 20 microns can cause obvious abrasion of the blades and even surge of the compressor, seriously affect the performance and safe operation of a unit and shorten the service life of the unit.
At present, gas turbine inlet air filtering systems mostly adopt common plate filters, bag filters or cylinder type self-cleaning filters with pulse back-blowing self-cleaning functions. The filter screens of common plate filters and bag filters are generally divided into three stages of primary effect, intermediate effect and high efficiency. The primary filter screen is replaced once in 1-3 months. The medium-efficiency filter screen is replaced once in 3 to 6 months. The high-efficiency filter screen is replaced once in 6-12 months. The material is generally PP filter paper, glass fiber, melt-blown non-woven fabric and other materials, and is of a microporous structure, and the size of the pores determines the size of the filtered particles. Compared with common plate filters and bag filters, the cylindrical self-cleaning filters mainly utilize compressed air to carry out back flushing on filter elements so as to achieve the aim of cleaning filter screens, prolong the service life of the filter screens and replace the filter screens once in about 1 to 2 years (different according to different air humidity).
The problems of the existing filtering systems are that: on the one hand, its performance attenuates gradually along with the live time increases, and is lower and lower, until changing the filter screen, not only influences work efficiency, still causes secondary pollution. On the other hand, the influence of air humidity easily causes bag sticking, causes different visual ranges, reduces efficiency or causes machine halt.
