The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of boiler vacuum pipe solar air preheater is provided, gathering and utilize solar radiation can be to the boiler transfer heat, reduce the consumption of traditional fuels such as coal and oil, thereby reach energy-saving and cost-reducing effect.
Vacuum pipe solar air preheater described in the utility model includes collection blast cap, air header, through double glazing solar vacuum heat-collecting pipe, induced duct, bypass air door, air blast and ajutage and forms.Cooperate with the steam generator system of prior art, form the energy conserving system of boiler jointly.In this case, whole steam generator system then includes collection blast cap, air header, through double glazing solar vacuum heat-collecting pipe, induced duct, bypass air door, air blast, ajutage, boiler, economizer, deduster, air-introduced machine and chimney composition.The air header is horizontal ventilation shaft, between the ventilation header, is vertically disposed form, is provided with through double glazing solar vacuum heat-collecting pipe.One end of air header is set to outer port, and the outer port of said air header is provided with the collection blast cap.Through the air of through double glazing solar vacuum heat-collecting pipe heating, the air header that is provided with by other is connected to induced duct and draws, and the power source of air inducing is an air blast.By the air header to the induced duct of air blast, be provided with the bypass air door.Air blast is connected with ajutage between the boiler, through ajutage hot-air is delivered in the boiler.The rear end of boiler then is provided with economizer according to prior art, and economizer is connected to deduster, connects air-introduced machine behind the deduster, and air-introduced machine is connected to the chimney emptying.
Wherein,, be provided with wave parabolic type mirror surface, the sunlight of vacuum tube neutral gear is reflexed to solar vacuum heat-collecting pipe to greatest extent in through double glazing solar vacuum heat-collecting pipe bottom.Outer surface at the inner glass tube of through double glazing solar vacuum heat-collecting pipe is coated with solar energy absorbing coating, improves the absorption efficiency of solar energy.
Principle of the present utility model is by the collection blast cap air to be sucked through double glazing solar vacuum heat-collecting pipe, through double glazing solar vacuum heat-collecting pipe adds hot-air under irradiation of sunlight, hot-air is sent into boiler furnace through air header, induced duct, air blast and ajutage.Good when the weather condition, when through double glazing solar vacuum heat-collecting pipe came into operation, the bypass air door was closed.Because boiler is a kind of special heat exchange container in essence, send into both boiler water of the final heating work medium of heat of the hot-air of boiler, and improve the boiler furnace burning condition, reach fuel-saving purpose.The effect of collection blast cap mainly be prevent rainwater enter the damage vacuum heat collection pipe.
Should determine whether through double glazing solar vacuum heat-collecting pipe comes into operation according to weather condition, operate very simple, close the bypass air door vacuum pipe solar air preheater that can come into operation, open the bypass air door and can close the vacuum pipe solar air preheater, and reduce the power consumption of air blast.But the manual operation of bypass air door also can be by the YE straighforward operation, comes into operation and to close the flexible operation of vacuum pipe solar air preheater simple.Whether the vacuum pipe solar air preheater comes into operation, may minimal effect be arranged to the combustion conditions of boiler, but can satisfy the requirement of boiler output by the adjustment of combustion apparatus, because the thermal inertia of boiler itself, can be to factory with hot production equipment generation harmful effect.
Advantage of the present utility model is: the heat that solar energy produces is sent into boiler by through double glazing solar vacuum heat-collecting pipe, save traditional fuels such as fire coal; The air that boiler combustion is needed absorbs the medium of solar energy as the vacuum pipe solar air preheater, sends into boiler by air blast, does not need existing boiler is carried out complicated transformation, saves transformation funds; Come into operation and to close the vacuum pipe solar air preheater swift to operate flexibly, the boiler operatiopn state is not produced strong the interference, satisfy the instructions for use of boiler; Use air to make heat-carrying agent, make that vacuum pipe solar air preheater component weight is light, can lay on general factory building roof, can play indoor heat-blocking action summer.The utility model overall structure is simple, and is easy for operation, good stability, and the reliability height, energy-saving effect is remarkable.
