Abstract

The utility model relates to an intercooling tower hot-air recycling system in a thermal power plant. The intercooling tower hot-air recycling system comprises a boiler, air blowers, primary air fans and auxiliary engine cooling water intercooling towers. Suction openings of the air blowers and suction openings of the primary air fans are arranged at hot air exhaust openings of the auxiliary engine cooling water intercooling towers. Air outlets of the air blowers and air outlets of the primary air fans are communicated with a furnace hearth of the boiler. Compared with the prior art, the intercooling tower hot-air recycling system has the advantages of recycling heat of gas exhausted from the intercooling towers, saving high-quality steam and improving economical efficiency of a thermal power generation system. In the intercooling tower hot-air recycling system, the heat of the gas exhausted from the intercooling towers in the thermal power plant is utilized and waste heat is changed into useful heat so that high-quality steam is saved. Therefore, the intercooling tower hot-air recycling system has important significance for energy saving of the thermal power plant.

Description

Thermal power plant indirect cool tower hot blast recycling system
[technical field]
The utility model relates to the thermal power generating technology field, particularly a kind of thermal power plant indirect cool tower hot blast recycling system.
[background technology]
In recent years, along with China's rapid economy development, the resource environment problem becomes increasingly conspicuous, and the energy-saving and emission-reduction situation is very severe, how to reduce investment for the thermal power plant, improves economy, need be from every side, each parts analyzes consideration.
In the prior art, the air outlet of the subsidiary engine cooling water indirect cool tower in the thermal power plant directly enters atmosphere with hot-air, and boiler need be provided with steam air heater through the air in the high-quality Steam Heating entering boiler air preheater, and the wasting of resources is bigger.
[utility model content]
The purpose of the utility model provides a kind of thermal power plant indirect cool tower hot blast recycling system, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
A kind of thermal power plant indirect cool tower hot blast recycling system comprises boiler, pressure fan, primary air fan and subsidiary engine cooling water indirect cool tower; The inlet scoop of pressure fan and primary air fan is positioned at the hot-air outlet place of subsidiary engine cooling water indirect cool tower; The air outlet of pressure fan and primary air fan is communicated with the burner hearth of boiler.
The utility model further improves and is: the air outlet of pressure fan and primary air fan is communicated with the burner hearth of boiler through the air preheater of boiler.
The utility model further improves and is: be provided with steam air heater between the air outlet of pressure fan and primary air fan and the air preheater.
Compared with prior art, the utlity model has following advantage: the heat that 1, has reclaimed indirect cool tower discharge gas; 2, practiced thrift high-quality steam; 3, improved the economy of thermal power plant system; Native system utilizes power plant's indirect cool tower to discharge the heat of gas, and change used heat is useful heat, practices thrift high-quality steam, has great significance for the energy-conservation of power plant.
[description of drawings]
Fig. 1 is the structural representation of the utility model.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
See also shown in Figure 1ly, a kind of thermal power plant of the utility model indirect cool tower hot blast recycling system comprises boiler 1, pressure fan 2, primary air fan 3 and subsidiary engine cooling water indirect cool tower 4.
The utility model is connected to the air draught pipeline of pressure fan 2 and primary air fan 3 outlet of subsidiary engine cooling water indirect cool tower 4; Utilize the medium of the hot-air of subsidiary engine cooling water indirect cool tower 4 discharges as the boiler air preheater import; Get into boiler furnace through air preheater then, thereby practiced thrift the high-quality steam of utilizing steam air heater heating air preheater import cold air.Under the enough situation of the hot air temperature that the utility model is discharged at subsidiary engine cooling water indirect cool tower 4, can cancel the steam air heater that heating pressure fan 2 and primary air fan 3 suck gases, perhaps reduce the amount that steam air heater consumes high-quality steam.
Two subsidiary engine cooling water indirect cool towers 4 of every boiler 1 include two cooling units, and two subsidiary engine cooling water indirect cool towers 4 are arranged in the both sides of boiler 1, and are corresponding with two pressure fans 2 and two primary air fans 3 of every stove 1.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
