Description
Technical field
The invention belongs to the technical field of heating system, relate in particular to the direct-connected heating system in the high district of skyscraper and low district.
Background technology
The heating circulatory system of skyscraper must be divided into high district and two systems in low district or two above systems by floor height, guarantees respectively to distinguish the safety of radiator in the heating system.In existing heating system, when high district and low district share a direct-furnish pipe network, the water supply of high sound zone system be the circulating pump that boosts by special use as power, by water main water is conducted to high district.Install decompression venting valve additional at the backwater main, the backwater static pressure is dropped to low district pressure of return water equate to link to each other with low district after (usually selecting greater than 0.01-0.02Mpa), to reach whole pipe network balance.
When skyscraper was independent thermal source, the heating endless form and the above-mentioned principle that generally adopt at present were basic identical, and the heating system layout that possesses independent thermal source has following two kinds of situations:
1, the independent boiler room of high-rise building design or independently high temperature heat exchange station, Qi Gao district and low district share a thermal source, and the circulatory system is separately systems independently of two covers, establishes two cover circulating pumps, respectively is a preparation and a use.The heating recirculation after behind the pressure-reduced and-regulated and low district backwater is got back to same boiler or high-temperature heat-exchanging by common backwater main of high district backwater.
2, set up separately independently boiler or high temperature heat exchange station independent loops fully separately by height district and low district, two cover circulating pumps respectively are one to be equipped with a usefulness, are two fully independently systems.
As shown in Figure 1, skyscraper possesses traditional heating system of the thermal source of independent special use, the heating system schematic diagram of the shared boiler in promptly high and low district, Tu Zhonggao district and the shared thermal source in low district, only providing with the normal-pressure boiler among the figure is the signal of independent thermal source, and other thermal source roughly the same.
Fig. 1 is the shared boiler schematic diagram in high and low district, use independent boiler dedicated separately as high and low district, 41,42 feed water valves among the figure then, 43,44 back-water valve (BWV)s are connected to boiler dedicated separately entry and exit and are the boiler dedicated separately circulatory system, so attached diagram in addition not.
The heating thermal source of skyscraper is independent special-purpose, and its heat supply system is not limited by city connection sheet heat supply network, in operational management considerable advantage and flexibility is arranged.But because circulating pump will be equipped with two covers or specialize in respectively high district and low sound zone system more than two covers, its operation and attendant's workload is many, it is big that pipe-line system layout and electromechanical equipment are put take up room position and material usage, and to overlap circulating pump institute power consumption many more.
Summary of the invention
Technical problem at above-mentioned existence, the invention provides a kind of need one cover circulating pump system, and corresponding operation maintenance operating personnel's workload only is equivalent to 50% the direct-connected heating system in high district of a kind of skyscraper and low district of former workload.
The present invention is achieved in that normal-pressure boiler links to each other with the boiler export valve by pipeline, and link to each other with heat exchanger through heat exchanger high temperature side inlet valve, after the heat exchange by heat exchanger high temperature side outlet valve and pump entry valve, cross water circulating pump, water circulating pump outlet non-return valve, pump discharge valve and link to each other, link to each other with the height district by the high water filling isolated controlling valve of distinguishing again; The return main in high district links to each other with heat exchanger by high district backwater decompression venting valve He Gao district back-water valve (BWV), links to each other with low district by heat exchanger low temperature side outlet valve after the heat exchange; Low district by connection valve, automatic open and close valve, automatic open and close valve before water return pipeline and dirt separator early gate, dirt separator, the automatic open and close valve after connection valve link to each other, link to each other with boiler by the boiler blow-down water main valve.
Described high district and low district can also be multi-region.
The direct-connected heating system in the high district of skyscraper and low district, it is characterized in that boiler links to each other with the boiler export valve by pipeline, heat exchanger high temperature side inlet valve links to each other with heat exchanger, after the heat exchange by heat exchanger high temperature side outlet valve and pump entry valve, cross water circulating pump, water circulating pump outlet non-return valve, pump discharge valve and link to each other, link to each other with the height district by the high water filling isolated controlling valve of distinguishing again; The return main in high district links to each other with heat exchanger by high district backwater decompression venting valve He Gao district back-water valve (BWV), links to each other with low district by heat exchanger low temperature side outlet valve after the heat exchange; Low district links to each other with connection valve before dirt separator early gate, dirt separator, the automatic open and close valve by water return pipeline, links to each other with boiler by the boiler blow-down water main valve, and boiler wherein can be bearing boiler or high-temperature water heat exchange station.
Advantage of the present invention is: a circulating pump just can guarantee the normal circulation of the two or more heating systems in skyscraper Zhong Gao district and low district, save manpower, conveniently manage, reduce investment outlay, save especially electric power resource, be applicable to that all possess the heating engineering of the high-rise of independent thermal source ability, therefore the scope of application is wide, high-temperature water heat exchange station applicable to normal pressure and pressure-bearing thermal source and urban district has considerable economic and social benefit.
