Description
Technical field
The utility model relates to a kind of boiler of power plant air inlet system, is specifically related to a kind of Air-cooled Unit inlet air of boiler system.
Background technology
The air cooling principle of Air-Cooling Island is that exhaust steam after the steam turbine acting steam exhaust device through low pressure (LP) cylinder bottom enters main blow-off line and is delivered to Air-Cooling Island steam-distributing pipe, by air cooling blower fan, the heat in heat radiation tube bank is taken away, and exhaust steam is condensed into condenses.Air-Cooling Island outlet hot-air is 40～5O ℃ approximately, and general directly row people atmosphere, had both wasted a large amount of heats, again environment had been produced to certain thermal pollution.
The air that enters boiler of power plant need to be preheating to uniform temperature through air preheater, and especially in the winter time, the air that enters boiler also needs to heat air intake by steam air heater, in order to avoid air preheater dewing corrosion.
Utility model content
The purpose of this utility model is to provide a kind of can realization to transfer the hot air discharge of Air-Cooling Island to enter in boiler air, without boiler air preheating, saves the energy, the convenient Air-cooled Unit inlet air of boiler system of implementing.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The utility model comprises hot-air gas collecting apparatus, air channel and blowing device;
Described hot-air gas collecting apparatus comprises Air-Cooling Island, is arranged at the hot-air collection chamber of Air-Cooling Island top;
Described blowing device comprises pressure fan and primary air fan;
Described air channel comprises the first air channel being connected with hot-air collection chamber and the second air channel being connected with atmosphere;
The crossing position in described the first air channel and the second air channel is provided with for controlling the fan blade of wind direction, the hinged sidewall that is arranged at described the first air channel in upper end of described fan blade;
The crossing position in described the first air channel and the second air channel is also provided with the horizontal baffle of horizontal direction locking fan blade and the vertical baffle of vertical direction locking fan blade.
The beneficial effect that adopts technique scheme to produce is:
The utility model collects the hot-air of Air-Cooling Island by hot-air collection chamber, and by air channel, transfer to the air inlet of boiler, realized the recycling of Air-Cooling Island hot-air, avoided it to be directly distributed to the thermal pollution that atmosphere causes, and can save the heating acting of boiler air preheater to air, effective use of energy sources resource.
The first air channel of the present utility model is communicated with hot-air collection chamber, the second air channel is communicated with atmosphere, and utilizes fan blade to realize the opening and closing in air channel, when Air-Cooling Island turns round, the pressure fan of inlet air of boiler mouth and the first blower fan are opened, and extract the hot-air in hot-air collection chamber; When Air-Cooling Island does not turn round, can regulate fan blade angle, the first air channel is closed, the pressure fan of inlet air of boiler mouth and the first blower fan extract the air in atmosphere after opening, and guarantee the operation of boiler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In the accompanying drawings: 1-1 Air-Cooling Island, 1-2 hot-air collection chamber, 2-1 the first air channel, 2-2 the second air channel, 3-1 pressure fan, 3-2 primary air fan, 4 fan blades, 4-1 horizontal baffle, 4-2 vertical baffle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises hot-air gas collecting apparatus, air channel and blowing device; Described hot-air gas collecting apparatus comprises Air-Cooling Island 1-1, is arranged at the hot-air collection chamber 1-2 of Air-Cooling Island 1-1 top; Described blowing device comprises pressure fan 3-1 and primary air fan 3-2; Described air channel comprises the first air channel 2-1 being connected with hot-air collection chamber 1-2 and the second air channel 2-2 being connected with atmosphere; The crossing position of described the first air channel 2-1 and the second air channel 2-2 is provided with for controlling the fan blade 4 of wind direction, the hinged sidewall that is arranged at described the first air channel 2 in upper end of described fan blade 2-3; The crossing position of described the first air channel 2-1 and the second air channel 2-2 is also provided with the horizontal baffle 4-1 of horizontal direction locking fan blade 4 and the vertical baffle 4-2 of vertical direction locking fan blade 4.
The utility model is in use: Air-Cooling Island 1-1 produces hot-air when using air displacement heat energy cooling, the air that the pressure fan 3-1 of boiler and primary air fan 3-2 extract in hot-air collection chamber 1-2 produces negative pressure, the hot-air that Air-Cooling Island 1-1 produces is enriched in faster hot-air collection chamber 1-2 and by the first air channel 2-1, enters pressure fan 3-1 and the primary air fan 3-2 of boiler, realizes the recycling of hot-air.Under this state, fan blade 4 is subject to the impact of air pressure, keeps vertical state, and vertical baffle 4-2 stops fan blade to be subject to gas pressure skew deviation, plays the effect of locking, the second air channel 2-2 sealing.
When Air-Cooling Island 1-1 maintenance or other situation do not turn round, when the pressure fan 3-1 of boiler and the first blower fan 3-2 extracting air, due to the air that cannot extract in hot-air collection chamber 1-2, make fan blade 4 become horizontal direction from vertical direction, the first air channel 2-1 sealing, the second air channel 2-2 opens, and the air suction pressure fan 3-1 in atmosphere and the first blower fan 3-2 guarantee boiler running.
The utility model collects the hot-air of Air-Cooling Island by hot-air collection chamber, and by air channel, transfer to the air inlet of boiler, realized the recycling of Air-Cooling Island hot-air, avoided it to be directly distributed to the thermal pollution that atmosphere causes, and can save the heating acting of boiler air preheater to air, effective use of energy sources resource.
