Description
Technical field
The utility model relates to steam generator system heat supply process field, particularly the annular circulation centralized heating net of connecting of the two stations single loops taking multiple steam generator systems as supplying heat source.
Background technology
Prior art, in city, adopting boiler is that supplying heat source central heating network technology is the most general form, it is to be to provide the outlet conduit of hot water and the water return pipeline of time cold water or warm water for hot-zone with heating network.Must turn back to for hot-zone through the outlet conduit that in water return pipeline turns back to former boiler room, circulation enters into out hot water after Pressurized-heated again for the backwater of hot-zone.The problem that this traditional heat-supplying mode exists is: area of heat-supply service is larger, and the caliber of required pipeline is just larger, and round pipeline is just longer, has directly taken the degree of depth of ground width and buried pipes, has greatly increased heat cost.In addition, existing heating network due to system heat supply far and near distance not etc., the cycle-index of heating system is inconsistent, can cause closely apart from supplying heat source, heating system cycle-index is that heating effect is all right more.And far away apart from supplying heat source, heating system cycle-index is just fewer, and heating effect obviously reduces, and this is the inconsistent temperature imbalance causing of flow due to heating system.
In order to alleviate the unbalanced problem of heating system temperature, particularly consider hot-zone, can only adopt existing first-level pipeline network heat supply standard apart from far away the supplying of supplying heat source, leaving water temperature is brought up to 180 DEG C of left and right, and raising discharge pressure, needs to build heat exchange station, pressurizing point etc. along pipeline more.The more important thing is that the selected boiler of supplying heat source must be bearing boiler because water moderate pressure improves.So just strengthen heat cost and had operating potential safety hazard especially.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of two station single loops annular circulation centralized heating net of connecting.It can reduce heat cost greatly, has particularly solved for the unbalanced problem of temperature between hot-zone.Have save floor occupying area, efficient energy-saving and emission-reducing, investment and low, the safe and reliable feature of operating cost.
In order to realize foregoing invention object, the technical solution of the utility model realizes as follows:
A kind of two station single loops annular circulation centralized heating net of connecting, it comprises two groups of heating boilers and the pressurized circulation equipment mating with it.Its design feature is that described heating boiler one forms two website supplying heat sources with pressurized circulation equipment one, heating boiler two with pressurized circulation equipment two.The delivery port of heating boiler one is connected with the delivery port pipeline of imperial palace ring heating network, the water return outlet of pressurized circulation equipment one is connected with the delivery port pipeline of little outer shroud heating network, the delivery port of heating boiler two is connected with the delivery port pipeline of little interior ring heating network, and the water return outlet of pressurized circulation equipment two is connected with the water return pipeline of large outer shroud heating network.On described little interior ring heating network, little outer shroud heating network and large outer shroud heating network, large outer shroud heating network, be equipped with several multipair by the each heating network of stop valve control and the delivery port and the water return outlet that communicate for hot-zone.
At above-mentioned two stations, single loop is connected in annular circulation centralized heating net, and described heating boiler one is arranged at corresponding position, large outer shroud heating network both sides in addition with heating boiler two.
At above-mentioned two stations, single loop is connected in annular circulation centralized heating net, and described pressurized circulation equipment one and pressurized circulation equipment two are made up of multiple force (forcing) pumps, stop valve and check/stop valve.
The utility model is owing to having adopted said structure, by setting up two positions supplying heat source of correspondence mutually, according to above-mentioned pipe network connection, the water return pipeline that can realize a supplying heat source no longer necessarily returns to former boiler room, but enter into nearby in another boiler room, in the situation that almost there is no thermal loss, heat again pressurization, become hot water and get back in network and recycle again.Thereby floor space that pipeline need to be round and round pipeline are saved and the thermal energy that loses.Realized save floor occupying area, the object of efficient energy-saving and emission-reducing.Again because the outlet conduit of two supplying heat sources is simultaneously to for hot-zone hot-water supply, solved for the temperature imbalance problem between hot-zone, also need not adopt and add the caliber of large pipeline and improve water moderate pressure, build the method for heat exchange station, pressurizing point along pipeline, greatly reduce investment and the operating cost of heating system, and safe and reliable to operation.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Brief description of the drawings
Accompanying drawing 1 is structure principle chart of the present utility model.
Detailed description of the invention
Referring to accompanying drawing, the single loops annular circulation centralized heating net of connecting in the two station of the utility model comprises two groups of heating boilers and the pressurized circulation equipment mating with it.Heating boiler 1 forms two website supplying heat sources with pressurized circulation equipment 1, heating boiler 22 with pressurized circulation equipment 24.The delivery port of heating boiler 1 is connected with the delivery port pipeline of imperial palace ring heating network 7, the water return outlet of pressurized circulation equipment 1 is connected with the delivery port pipeline of little outer shroud heating network 6, the delivery port of heating boiler 22 is connected with little interior ring heating network 5 delivery port pipelines, and the water return outlet of pressurized circulation equipment 24 is connected with the water return pipeline of large outer shroud heating network 8.On little interior ring heating network 5, little outer shroud heating network 6 and large outer shroud heating network 7, large outer shroud heating network 8, be equipped with several multipair by the each heating network of stop valve control and the delivery port and the water return outlet that communicate for hot-zone.Heating boiler 1 is arranged at corresponding position, large outer shroud heating network 8 both sides in addition with heating boiler 22.Pressurized circulation equipment 1 and pressurized circulation equipment 24 are made up of multiple force (forcing) pumps, stop valve and check/stop valve.
The utility model is in service, all same as the prior art, seldom repeats.Difference be the heating boiler of each supplying heat source by the connected mode of above-mentioned pipeline, can realize and enter for each position heat of hot-zone substantially balanced for the delivery port hot water in hot-zone pipe network.Respectively enter in the water return pipeline for hot-zone pipe network for the backwater unification after the heating of hot-zone in addition, the backwater of each position can enter among pressurized circulation equipment nearby, after heating boiler heats pressurization again, turn back among the outlet conduit for hot-zone pipe network, recycle.
