Abstract
The utility model provides a heating system formed by using temperature-rise heat energy of a bulb through-flow water turbine generator set. The bulb through-flow water turbine generator set comprises a generator and a water turbine, wherein the generator comprises an outer shell body, stator portions and a rotor portion are arranged in a chamber arranged inside the generator, two channels are arranged on the outer shell body of the generator, the two channels include a cold air inlet channel and a hot air outlet channel, the two channels are communicated with a workshop, an axial flow fan is further arranged in the chamber arranged inside the generator, an open type air circulating structure is formed by the generator, the channels and the workshop, and the axial flow fan is installed on one side close to the cold air inlet channel. According to the heating system formed by using the temperature-rise heat energy of the bulb through-flow water turbine generator set, the heat energy of temperature rise of the water turbine generator set of a hydropower station is transmitted to the workshop of the hydropower station, the problem that the temperature of the workshop in winter is excessively low is solved, and consumption of a large amount of electric energy is avoided.
Description
Technical field
The utility model belongs to hydraulic turbine technical field of power generation, is specifically related to a kind of heating system that utilizes the temperature rise heat energy formation of bulb through-flow hydraulic turbine generator group.
Background technology
The Northeast's factory building temperature in winter is low especially, and a lot of power stations are crossed when low in the factory building temperature, for guaranteeing safe, stable, the reliability service of each equipment, can only drop into a large amount of electric heating and guarantee the factory building temperature.So not only consume a large amount of electric energy, cause very big hidden danger also for the safety in production in power station.
There is following potential safety hazard in the factory building temperature when low excessively:
1, malfunction or tripping easily take place at low temperature environment to the hydraulic generator unit in moving control element, thermometric, frequency measurement, protection, measurement etc. separately;
2, easily cause turbine oil viscosity to increase, cause flow velocity slow excessively, influence the lubricant effect of turbine oil;
3, the pipeline that each water system, drainage system easily take place freezes, thereby causes very big economic loss, more threatens the safe operation of generating set.
And as core---the bulb through-flow turbine generating set in power station, its according to the heating temp of generator code requirement stator, rotor portion generally at 120 ℃ to 130 ℃.In fact, when generating set moves under rated power, stator temperature generally is no more than 90 ℃, traditional way is will be by supply water to reduce the temperature rise of generator to air cooler, as shown in Figure 1, the shell body of generator seals, and it adopts airtight air inner circulation structure to take away the disadvantageous temperature rise of generator by air cooler, does the huge waste that then causes temperature rise heat energy like this.
The utility model content
The utility model provides a kind of heating system that utilizes the temperature rise heat energy formation of bulb through-flow hydraulic turbine generator group, send the heat energy of power station hydraulic turbine generator group temperature rise to powerhouse of hydropower station, temperature is crossed in the low problem in solving the factory building in winter, avoids consuming a large amount of electric energy.
Concrete technical scheme of the present utility model is as follows: the heating system that utilizes the temperature rise heat energy formation of bulb through-flow hydraulic turbine generator group, the hydraulic turbine generator group comprises generator and the hydraulic turbine, wherein generator has in the chamber of shell body and generator inside and has stationary part, rotor portion, shell body at generator is provided with two passages, namely advance cold air duct and go out hot-air channel, two passages communicate with factory building respectively, in the chamber of generator inside, also be provided with an axial flow blower, form an open-type air circulation structure by generator, passage and factory building.
Axial flow blower is installed near a side of advancing cold air duct.
The beneficial effects of the utility model: the utility model is not by supplying water to reduce the temperature rise of generator to air cooler, but the heat energy that utilizes the generator temperature rise offers factory building in order to heating, make simple and easy to do, when having guaranteed factory temperature in winter, avoided a large amount of wastes of station service, reduced economic loss, improved economic benefit, also provide guarantee for the safe fire-fighting production in power station., very big to the relevant enterprise energy-saving potential, have dissemination; Axial flow blower is installed near a side of advancing cold air duct can strengthens the speed of circulation of air, promote the heating effect of factory building.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, utilize the heating system of the temperature rise heat energy formation of bulb through-flow hydraulic turbine generator group, the hydraulic turbine generator group comprises generator and the hydraulic turbine, wherein generator has in the chamber of shell body and generator inside and has stationary part 3, rotor portion 4, shell body at generator is provided with two passages, namely advance cold air duct 1 and go out hot-air channel 2, two passages communicate with factory building respectively, in the chamber of generator inside, also be provided with an axial flow blower 5, form an open-type air circulation structure by generator, passage and factory building.
During operation, the generator internal chamber sucks natural cold air by advancing cold air duct, natural cold air is taken the temperature rise of iron core and spiral out of when the stationary part 3 that passes through generator, rotor portion 4, and pass out to out hot-air channel 2 by axial flow blower 5, thereby heat is discharged in the generator factory building.
The applicant adopts technique scheme, measures generating set through terrain and goes out the air themperature of hot-air channel 2 between 25 ℃ to 35 ℃.And find that through record when outdoor temperature is-20 ℃ in the winter time, and do not add under the condition of any measures of heating such as electric heating at factory building, the factory building room temperature can remain between 5 ℃ to 8 ℃; When outdoor temperature was-28 ℃, the interior temperature of factory building is minimum to be 5 ℃.This shows that the technical program can be guaranteed safety, the stable operation of each equipment in the factory fully.
