A large gas turbine intake system cleaning equipment

Abstract

The invention discloses cleaning equipment for air inlet systems of large gas turbines. The cleaning equipment comprises a double-screw air compressor, wherein the double-screw air compressor is connected with a first gas storage tank; one end of the first gas storage tank is connected with a solenoid valve by the aid of a one-way valve; the solenoid valve is connected with a pressure reducing valve, the one-way valve, a pressure switch, a thermometer and a temperature switch; the first gas storage tank is connected with a first primary filter by the aid of a lead; the first primary filter is connected with a first precision filter, a first non-heat-adsorption type drying machine, a second precision filter and a valve in series; the first primary filter is connected with a second gas storage tank in parallel; and the second gas storage tank is connected with a second primary filter, a third precision filter, a second non-heat-adsorption type drying machine and a valve in series. The cleaning equipment has the characteristics that back flushing is realized by the aid of tail gas produced by the gas turbines, meanwhile, instrument gas can be provided, when the unit is maintained, no tail gas is produced, but the compressor can work, and a stable gas source is provided.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to cleaning equipment for the intake system of a large gas turbine. Background technique [0002] The cleaning device used in the gas engine air intake system used in the prior art is usually uneven in blowing, and the filter elements need to be disassembled for cleaning and blowing, and the efficiency is very low. When there are many filter elements, the operating time is too long. And it is easy to pollute the dust inside the filter element. Shutdown is required for purging. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a method of blowing back using the exhaust gas generated by the gas turbine, and at the same time can provide instrument gas. When the unit is overhauled, there is no exhaust gas, but the compressor can work, providing Large gas turbine intake system clea...
