Efficient gas turbine intake air temperature adjustment system

Abstract

The invention discloses an efficient gas turbine intake air temperature adjustment system and relates to a gas turbine. The efficient gas turbine intake air temperature adjustment system comprises a hollow cooling and dehumidification main body. The cooling and dehumidification main body is internally provided with a pretreatment chamber, a multi-stage filtering chamber, a pre-dehumidification chamber and a cooling and dehumidification chamber in sequence from an air inlet to an air outlet, wherein the pretreatment chamber, the multi-stage filtering chamber, the pre-dehumidification chamber and the cooling and dehumidification chamber communicate with one another. The pretreatment chamber is internally provided with an air corrosion removal device. The pre-dehumidification chamber is internally provided with a dehumidifier, a humidity sensor and a first temperature sensor. The pre-dehumidification chamber is provided with a first air guiding opening and a second air guiding opening, wherein the flow rate of the first air guiding opening is greater than that of the second air guiding opening. The cooling and dehumidification chamber is internally provided with a surface air cooler and a mixing device. The surface air cooler comprises refrigerating coils. The refrigerating coils comprise the first coil and the second coil. An inlet of the first coil communicates with the first air guiding opening and is internally provided with refrigerant. An inlet of the second coil communicates with the second air guiding opening. The mixing device is provided with a first branch pipe, a second branch pipe and a header pipe. When the efficient gas turbine intake air temperature adjustment system is used for cooling and dehumidifying air, losses of the cooling capacity and the heating capacity are remarkably reduced, and energy conservation and consumption reduction are achieved.

Description

technical field [0001] The invention relates to a gas turbine, in particular to a high-efficiency gas turbine inlet temperature regulating system. Background technique [0002] A gas turbine is an impeller-type thermal power machine that uses gas as its working medium, internal combustion, and continuously rotates. It is mainly composed of three major components: a compressor, a combustion chamber and a gas turbine. The compressor continuously inhales air from the outside and pressurizes it, and at the same time, the temperature of the air increases accordingly; , High-pressure gas; the gas expands in the turbine to do work, pushing the turbine to drive the compressor and generator to rotate at high speed together; the exhaust gas discharged from the turbine is discharged to the atmosphere to naturally release heat. In this way, the gas turbine converts the chemical energy of the fuel into heat energy, and part of the heat energy into mechanical energy. [0003] There are ...

Problems solved by technology

In this process, since the cooling capacity required by the air is much greater than the load of the room, the temperature of the low-temperature air caused by dehumidification is raised by the heater, which also consumes a large amount of heating capacity, and the loss of cold and heat neutralization is quite large.
