Description
The utility model relates to a kind of light radiation heating plant, particularly a kind of heater to building central heating heat supply water.
At present, be the heater of building central heating heat supply water, adopt with fire coal or fuel oil is the boiler of energy source more, and this kind boiler has been continued to use several centuries, although through repeatedly improving, does not break away from fire coal or fuel oil institute all drawbacks in generation yet.During as the transportation of fuel, storage, burning to the pollution of environment, the discharging of slag etc., remove the work fatigue in addition during burning boiler, outside working condition is arduous, to the operator strict specification requirement to be arranged also, because safety problem is a significant problem in the heat and heat water supplying system, there is carelessness that the danger of breeding disaster is just arranged slightly, builds the boiler room in addition and not only will exhaust great amount of manpower and material resources, financial resources, also will take the construction area of a lot of preciousnesses.
Be dispersed in that space heater in the user, electric heater, air-conditioner etc. are low because of its thermal efficiency again, power consumption is big, price is higher, is not easy to reasons such as centralized management, also can't popularize.
The purpose of this utility model is that will to provide a kind of be the light radiation heater of the energy with the electricity, and it can overcome fire coal, and all drawbacks during oil burning boiler work are greatly more energy-conservation and be convenient to centralized management than space heater, electric heater, air-conditioner etc. again.
The purpose of this utility model is achieved in that this heating plant is a principle of utilizing light radiation, convert electrical energy into luminous energy by light-emitting component, through special reflector luminous energy is gathered a specific place to high-density again, the luminous energy that is gathered together by such several light sources and reflector has formed a high energy field, place the heat exchanger of this high energy field, absorb luminous energy and be converted to heat energy again, water is heated when over-heat-exchanger, be transported to each user through the heat and heat water supplying pipeline again, last backwater and supplementing water return this heater, continue to be heated, form a circulation.
A kind of light radiation heating plant, by the light radiation heater, heat exchanger and switch board are formed, it is characterized in that described light radiation heater is made of electric light source and reflector, described electric light source is a halogen tungsten lamp, electric light source is installed on the end plate (6) by tube stand (4) and hold-down screw (5), described reflector is that a kind of cross section is parabola shaped reflector (10), this reflector (10) has a reflector cavity (16), on cavity (16) two end plates (6) the cooling water Inlet and outlet water is installed and chews (1), electric light source is fixed on reflector parabolic surface (10A) focal position by the support that is installed in reflector two end plates (6) (4), with n(n 〉=1) individual described reflector gets up just to constitute the light radiation heater assembly by certain textural association, place the pipe (18) of the heat exchanger of this device to fix by the heat transfer tube bundle ring flange (23) at tube bank two ends, return pipe (29) is joined by water pipe ring flange (21) and heat exchanger tube ring flange, and backwater enters heat exchanger tube (18).Described electric light source is to be mounted with filament (7) in a quartz burner (9), and filament (7) is supported by filament support ring (8), and partly seal lead (2) bare wire with ceramic lamp angle (3) at the electric light source two ends.N(n 〉=1) individual reflector is by columnar structured arrangement.N(n 〉=1) individual reflector is arranged by planar structure.
This device is made up of following three parts: 1. light radiation heater, and 2. heat exchanger, 3. switch board below is illustrated respectively.
1. light radiation heater:
The light radiation heater is an important component part of the present utility model, and it is made of electric light source parts and reflector parts.
The electric light source parts mainly comprise: the bracket component of halogen tungsten lamp and this lamp and conducting wire, this lamp are connected and can be sent colour temperature behind power supply and be: 2800 °～3000 ° of K luminous fluxes are the high light of 40000Lm, and its working life can reach more than 3000 hours.
Reflector parts, mainly comprise reflector and water circulation system, reflector is through the extrusion process moulding with fine aluminium, its cross section is parabola shaped, its reflecting part is that parabolic surface is processed into minute surface through polishing, in the too high damage reflector of temperature and this reflector of minute surface a cavity is arranged when preventing work, recirculated water has been chewed cooling effect through the water flowing at water pipe and cavity two ends.
Halogen tungsten lamp is fixed on the position of reflector parabolic surface focus by the support that is installed on the reflector two end plates, connect power supply after, the high light that halogen tungsten lamp sends is assembled for collimated light beam to reflect away.
Get up by certain position grouping by such several reflectors, (planar alignment or one-tenth garden tubular are arranged, reverberation gathers together to high-density, form an energy field, heat exchanger promptly is seated in this energy field, and it has absorbed luminous energy and has been transformed into heat energy, and its temperature can reach more than 1250 ℃, water is heated when over-heat-exchanger, is transported to each user through the water pump pressurization by heating, heat supply waterpipe.
2. heat exchanger:
Heat exchanger is the parts of a power conversion, it absorbs luminous energy in the energy field of light radiation heater, be converted to heat energy, the height of its efficient depends on that it accepts the size of illuminating area and to the absorbability of light, this heat exchanger is to adopt the bundled tube structure, and tube bank is through sandblast, and surface coarsening is made through electroplating blackout again, with the light radiation Heater group altogether, its thermal efficiency can reach more than 85%.
