Description
Technical field
The utility model relates to a kind of heating system.
Background technology
Heat supply in winter is the living guarantee measure that the northern area of China must be implemented in winter.Along with development of market economy, heat supply in winter is supplied with by the Thermal Corp that occurs in the society mostly, this heating system belongs to central heating, it is the heat exchanger that vapours is transported to each heat supply zone by heat distribution pipe network, to finish by heat exchanger that the heating system by the sub-district heats to the user after the heat exchange, this heating system centrality is strong, the heat supply efficiency height, it is the main heating system of present China, but have the following disadvantages: 1, the heating poor reliability, when break down in the heating pipe network upstream, the heat exchanger in downstream will lose thermal source, and cause the resident to heat and be forced to interrupt, and when heat exchanger itself breaks down, downstream resident heating also is interrupted, and makes troubles to resident living; 2, existing small-scale Thermal Corp makes steam by fire coal, and environmental pollution is relatively large.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure at above-mentioned deficiency, and heating is reliable, pollute little, and the low heating system of operating cost.
For solving the problems of the technologies described above, this heating system comprises vapour source and the heat exchanger that is attached thereto, the backwater end of heat exchanger is equipped with circulating pump, and its design feature is: be parallel with electric boiler between the water supply end of heat exchanger and the backwater end, the water supply end of electric boiler is equipped with the electric boiler feed water valve.
This heating system is parallel with the electric boiler thermal source at the water side and the backwater end of heating heat exchanger thermal source, that is to say that hot water effluent's end of electric boiler is held with the hot water effluent of heat exchanger and is communicated with, the cold-water return end of electric boiler is communicated with the cold-water return end of heat exchanger, simple in structure, it is convenient to transform; This heating system, not only heat exchanger can heat to the user, and the backwater of returning from the user also can heat to the user after the electric boiler heating, and shared one overlaps hot duct and relevant device, has saved the integrated cost of native system; Electric boiler and heat exchanger generally are one and move another as standby, close heat exchanger when electric boiler moves, can overhaul by the heat exchanging device this moment, and when heat exchanger moves, can overhaul electric boiler, fundamentally improve the reliability of this heating system; Heat exchanger is operation by day mainly, no matter vapour source is to be provided or manufacturing voluntarily by other unit, its cost is certain, and when entering the period in the late into the night, heat exchanger cuts out, open electric boiler, use electric boiler to heat to the user, at dead of night the period, power consumption is at a low ebb, country carries out paddy section electricity price, use electric boiler heating Billy much lower with heat exchanger heat exchange heating cost, and environment friendly and pollution-free, help improving the environmental protection index in heat supply sub-district and city, and help the electrical network peak load shifting, the quality of power supply that improves paddy section electrical network is had certain benefit.
For the ease of safeguarding that the backwater end of electric boiler is equipped with the electric boiler back-water valve (BWV).
The water supply end of electric boiler is equipped with the electric boiler feed water valve, the backwater end of electric boiler is equipped with the electric boiler back-water valve (BWV), when heat exchanger moves, when perhaps needing to overhaul electric boiler, electric boiler feed water valve and electric boiler back-water valve (BWV) are all closed, hot water and cold water all can not flow to electric boiler like this, and is very convenient when the maintenance boiler.
In order to satisfy different heating demands, the quantity of described electric boiler is at least one.
When heating demand hour, only need to open an electric boiler, when the heating demand is big, open the electric boiler more than two or two, can satisfy user's different demands.
In sum, adopt the heating system of this structure, simple in structure, heating is reliable, pollutes for a short time, and operating cost is low, is adapted at using in city and the rural area central heating.
