For this purpose, the gas turbine has to extract the air in the gas turbine thermal power plant environment; in order to control the air quality entering the gas turbine to ensure the normal operation of the unit, a matched gas engine air inlet filter is required.
The unit generally adopts an imported brand gas engine, matched gas engine air inlet filtration is designed according to foreign countries, under the environment states of low temperature and high humidity, haze, ice and snow, foggy and flying catkin in winter in the north, as the temperature changes sharply, the air humidity tends to be saturated, when the filter cylinder filters air, the high humidity air and dust are blocked in the gap of the filter cylinder filter material through the throttling effect of the filter material, negative pressure suction is carried out when the gas compressor works, the flow speed is accelerated when the gas compressor passes through small holes, diffusion and speed reduction are carried out when the gas passes through the filter material, the high humidity air intercepted by the filter material is slowly formed into semi-solidified ice crystal particles, the filter material is partially blocked, the air inlet flow is reduced, the pressure difference of the filter is increased, and meanwhile, the environment temperature and humidity change again, and the filter operates in a negative feedback state. The differential pressure of the filter is abnormally increased, the air sucked by the gas compressor is reduced, the combustion of the gas engine is influenced, the load is reduced, the output power is reduced, and the gas engine is caused to run in a load-reducing mode or the high differential pressure of the air inlet filter is caused to jump.
Therefore, the filter matched with the gas inlet system of the gas turbine in the prior art can cause the surface blockage and freezing of the filter material of the filter when being used in severe environments such as low temperature, high humidity and the like in winter in northern China, and the pressure difference of the filter is abnormally increased, so that the filter cannot operate for a long period, and the normal operation of the whole unit is seriously influenced.
Disclosure of Invention
In order to overcome the defects in the prior art of gas turbine inlet filters and enable the gas turbine inlet filters to adapt to local environment requirements of Chinese gas turbine factories, the invention provides a filter for a gas turbine inlet, which has the following technical scheme:
a filter for gas turbine inlet includes a front end catkin net of air inlet, a rain cover, an anti-icing device connected with the heat source of the gas turbine system, a filter module, and a filter outlet pipe for connecting the air inlet of the gas turbine compressor.
In the scheme, the anti-catkin net is added to the air inlet filter, and when catkin flies, catkin is intercepted on the stainless steel wire net at the outermost layer of the filter; when catkin intercepts much, the catkin net can be reused by cleaning the net. A rain cover is additionally arranged at the rear of the catkin net so as to prevent rainwater from entering.
In addition, in the scheme, an anti-icing device is designed on the filter for easily generating freezing phenomena when the ambient temperature is low and the air humidity is high for the filter element in the filter module, namely, a heat source is introduced into the air inlet end face of the air inlet filter, the air inlet temperature of the filter is regulated to enable the air approaching humidity saturation, the relative humidity is reduced along with the rising of the air inlet temperature, the air at the air inlet of the filter passes through the filter element in an unsaturated vapor state, and the pressure difference of the filter is not increased.
The anti-icing device connected with the heat source of the gas turbine system can be a high-temperature gas spray pipe connected with an inlet air heating system (IBH) of the gas turbine, and can also adopt a tubular heat exchanger.
When the IBH high-temperature air spray pipe is adopted to introduce a heat source, an IBH pipeline at the outlet of a gas compressor is led to the front of a filter bag of a coarse filter element, high-temperature air about IBH (generally about 390 ℃) is mixed with the sucked high-humidity cold air by the spray pipe, and the temperature of the air inlet of the filter is increased; the filter is provided with a high-temperature air spray pipe during design and manufacture.
When the tubular heat exchanger is adopted to obtain a heat source, hot water (generally about 65 ℃) of a waste heat boiler generated by a combustion engine is used as the heat source, the tubular heat exchanger is utilized to exchange heat, the temperature of inlet air is increased, the saturation state of high-humidity air is broken, and the purposes of dehumidification and deicing are achieved; the tubular heat exchanger device is arranged during the design and manufacture of the filter.

The filter bag intercepts large-granularity dust, and the filter cartridge intercepts small-granularity dust, so that the filter dust holding capacity of the filter cartridge is reduced, and the filter cartridge is assisted with compressed air pulses. The service life of the filter cylinder is prolonged, and the filter cylinder is expensive due to the low price of the coarse filter bag, so that the consumable consumption of the filter element for operating the combustion engine is reduced. The whole operation pressure difference of the filter is reduced, the power generation and heat supply of the gas turbine unit are improved, and the economic benefit is also improved.

As a further improvement of the invention, the rain cover has a structure that a labyrinth passage is formed between the catkin preventing net at the front end of the air inlet and the anti-icing device according to the air filtering direction, and a dehumidifying plate capable of blocking moisture and humidity from entering is arranged in the labyrinth passage. As the water retaining and dehumidifying board is arranged in the labyrinth channel of the rain cover, rainwater and partial moisture do not enter the filter and are blocked.
Preferably, the catkin preventing net at the front end of the air inlet is a stainless steel wire net.
The beneficial effects of the invention are as follows:
