Description
Technical field:
This utility model is a kind of dust-proof deicer of the air inlet installed and used be applicable to gas turbine inlet air temperature elevation system.
Background technology:
At present the air inlet temperature elevation system of gas turbine is typically provided with pulse self-cleaning air filter; owing to filtering element for air filter has throttling effects of reduced temperature; when atmospheric temperature close to freezing point temperature and relative air humidity bigger time; a part of steam can condense into water droplet under throttling cooling effect; then one layer of frost is formed on air filtering core surface; blocking filter element mesh, the not only normal work of impact, also can affect air and enter gas turbine and cause shutdown.Existing gas turbine inlet air intensification filter element preventer has multiple, and one is electrical heating or steam heat-exchanging heating, and another kind is the recycling heating of hood circulated air.The former equipment is complicated, investment is big, energy consumption is high, practicality is poor, the hot-air that cooler is discharged by the latter causes supercharging at blower fan by the road, it is delivered in mixed heat exchanger, from heat exchanger, ejection mixes raising intake air temperature with gas turbine inlet air again, major defect is system complex, and energy consumption is high, also can be in hood and filter element produces oil vapour pollution.Also having by the way of at introduction high-pressure hot gas to primary air inlet filter element heating intake air temperature, the subject matter that this mode exists is, because the active force of nozzle upwards jet is strong, dust-proof deicing weak effect, reduces the service life of gas turbine.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in construction, the energy consumption dust-proof deicer of gas turbine inlet air low, length in service life.
The technical solution of the utility model completes as follows, a kind of gas turbine inlet air preventing dust ice production apparatus, it includes that adds a hot leg pipe, it is characterized in that: a shower nozzle is installed separately down at interval of 10-20 centimetre on the tube wall add hot leg pipe, add hot leg pipe and horizontally extend in an orientation air channel from one end, Pressure gauge after the inlet end adding hot leg pipe is drawn downwards and is provided with one, an exhaust tube it is horizontally installed with to side at the buffered device in rear manometric outer end, control valve and rear control valve before being separately installed with by two ends on exhaust tube, Pressure gauge before being provided with on the inlet end exhaust tube of rear control valve, the exhaust tube of front control valve outlet side is provided with a restricting orifice, inlet end at exhaust tube is provided with a wall-through flange, a threeway of bleeding is had in the connection of expanded section of wall-through flange outer end.Exhaust tube is a thermal-insulating type exhaust tube.
This utility model has simple in construction, energy consumption is low, can effectively reduce the impact on filter element of dust and frost, reduces equipment investment and operating cost, the advantage in extension device service life.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；Fig. 2 is the structural representation that this utility model is arranged on gas turbine.
Detailed description of the invention:
Embodiment is described in detail in conjunction with accompanying drawing, it includes that adds a hot leg pipe 12, the tube wall add hot leg pipe is provided with separately down a shower nozzle 10 at interval of 10-20 centimetre, add hot leg pipe and horizontally extend in an orientation air channel 11 from one end, Pressure gauge 8 after the inlet end adding hot leg pipe is drawn downwards and is provided with one, an exhaust tube 13 it is horizontally installed with to side at the buffered device in rear manometric outer end 9, control valve 4 and rear control valve 7 before being separately installed with by two ends on exhaust tube, Pressure gauge 6 before being provided with on the inlet end exhaust tube of rear control valve, the exhaust tube of front control valve outlet side is provided with a restricting orifice 5, inlet end at exhaust tube is provided with a wall-through flange 3, connect for expanded section 2 in wall-through flange outer end and have a threeway 1 of bleeding.Exhaust tube is a thermal-insulating type exhaust tube.Threeway of bleeding can realize taking online gas on the premise of not changing gas turbine structure；Expansion arc is for the expansion of metallic conduit high temperature conveying, wall-through flange is used for airtight for exhaust tube through gas turbine engine enclosure, the sealing and the hood ventilating system that do not affect hood itself are run, front and back control valve is for the regulation and control of rate of air sucked in required, adapt to the regulation under varying environment, only put into and operate under relatively overall situation demand；Restricting orifice is used for limiting rate of air sucked in required, it is designed by less than the standard of gas turbine blower 5, value is that the forcing press amount of calming the anger less than or equal to 3 configures, front and back Pressure gauge is used for monitoring operating pressure of bleeding, because of work and stable, safe and reliable can only make situ configuration, it is not necessary to teletransmission configures；Buffer for slow fall suction pressure fluctuation, being distributed in arm and reducing pneumatic noise evenly of bleeding；Shower nozzle sprays downwards and being arranged on arm the formation Jet with downward flow direction sealing gland in passage that makes to bleed; add bib aerofoil around arm surrounding and form orientation air channel; by semiclosed to arm and shower nozzle in air channel; the crosswind impact on shower nozzle can be reduced; make full use of heat energy, further through the change to wind direction of the lower air inlet mode, make larger particles dust remove; large granular impurity in air, water droplet being removed, the air simultaneously entering bottom open type orientation fan housing removes large granular impurity in air by baffling under gravity.Bleeding, on three exhaust tubes passing between buffer, heat-insulation layer is set, heat loss can be reduced；Exhaust tube and the wall-through flange on-link mode (OLM) of casing infall and expansion tube ensure that the sealing property of hood.
