Abstract
The invention provides a single-tube outer net circulating water system which consists of a user, an adjusting device, a heat source system, a heat source boiler, a heat source circulating pump, and an outer net pipeline, wherein the heat source boiler, the heat source circulating pump, the user and the adjusting device are connected in series by the outer net pipeline to form a closed circulating water system, and the user and the adjusting device are connected in parallel. In the single-tube outer net circulating water system of the invention, each heat exchanging station has a separated water-taking pump, the outer net circulating water only needs to ensure the sufficient flow, and can overcome the delivery lift of on-way resistance of the pipeline, reduces the delivery lift and the flow of a water pump, and at the same time, overcomes the heat imbalance problem of a two-pipe system.
Description
Technical field
The present invention relates to the single-tube outer net circulating water system in a kind of heating system.
Background technology
Heating system is heat exchange initial station to be set as thermal source in steam power plant, and the hot water of producing with plant condenser and peak load calorifier to a heat supply network transfer heat, is given heat delivery by the secondary heat supply network hot user's system as medium then.Along with the reinforcement of the environmental consciousness of urban construction, the central heating system of big thermal source has progressively replaced the direct supply system of little thermal source.Millions of square metres easily of area of heat-supply services, and also have the trend that continues increasing.The increasing of heat supply network causes investing the problem that increases and given prominence to the heat supply network management, and its difficult problem is exactly the thermodynamic equilibrium problem or the heat balance problem of heat supply network.The serious unbalanced system of heating power can cause the large-area cold-peace superheating phenomenon of crossing to take place, and make heating enterprise in the immense pressure of bearing society's complaint, also to disregard cost ground and solve the huge economic pressures that cold belt comes by strengthening the thermal source input.One time outer net thermodynamic equilibrium adjusting workload is increasing, more and more is not easy, and the thermal misadjustment of pipe network is thoroughly improved.
Existing two-pipe system can be big with hydraulic power near the user of boiler room, and heat is crossed Sheng since the pressure loss of pipeline the hydraulic power that can use of the terminal heat exchange station user on webmaster road is little outside, there is serious thermal misadjustment problem in shortage of heat.
Summary of the invention
In order to overcome in two-pipe system, user near the boiler room can be big with hydraulic power, heat is crossed Sheng, because the hydraulic power that can use of the terminal heat exchange station user on webmaster road is little outside for the pressure loss of pipeline, shortage of heat, have serious thermal misadjustment problem, the present invention proposes a kind of single-tube outer net circulating water system.
Technical scheme of the present invention is: a kind of single-tube outer net circulating water system is characterized in that: comprise the single tube outer net circulating water system that user, adjusting device, heat source system, thermal source boiler, thermal source circulating pump, outer net pipeline constitute; Wherein thermal source boiler, thermal source circulating pump, user and adjusting device are utilized the series connection of outer net pipeline, constitute closed circle water system; User and adjusting device are in parallel.
A kind of single-tube outer net circulating water system of the present invention is the single cycle pipeline, it goes out to cold from the heat of boiler, and to advance be to be made of a pipe, under the promotion of water pump, after outer net circulating water heats away from boiler, in outer net, take a round and get back to boiler and enter the mouth out and enter boiler, in the process of outer net circulation, each heat exchange station can enter the heat exchanger of heat exchange station according to water intaking pump of the increase in demand extracting high-temperature water from outer net of oneself, after finishing, heat exchange again a water is sent back in the outer net, in the system that does not take heat exchange, the high-temperature water that the water intaking pump extracts from outer net directly mixes the back with user's heating recirculated water and goes into low temperature heating recirculated water supply user heating.The primary side of heat exchanger need increase water water intaking pump one time in the heat exchange station of heat exchange, and the electric control valve of water circulating pump, the mixed coolant-temperature gage of control need be arranged in the system that does not take heat exchange.
In a kind of single-tube outer net circulating water system of the present invention, each heat exchange station has the pump of independently fetching water, outer net circulating water only need guarantee that flow satisfies, there is the lift that can overcome the pipeline on-way resistance to get final product again, reduce the lift and the flow of water pump, also overcome the thermal misadjustment problem in the two-pipe system simultaneously.
The single tube circulation has been compared following characteristics with two-tube circulation:
The pipe network investment: single-main distribution is saved 50% construction investment than two-pipe system;
The boiler room power consumption: single-main distribution saves 50% than two-pipe system;
Thermal energy consumption: single-main distribution saves 50% than two-pipe system;
Operational effect: reduce the thermal misadjustment problem greatly, operational effect is higher than two-pipe system;
Operation maintenance: the simplification of pipeline has reduced maintenance cost and difficulty.
Distributed single tube heat supply (outer net) system all has and obviously is better than traditional indirect heating mode and mixed water direct-furnish heating system building initial cost, operating cost, maintenance expense etc.For the heat supply field provides a kind of new method.

Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of single-tube outer net circulating water system comprises the single tube outer net circulating water system that user 1, adjusting device 2, heat source system 3, thermal source boiler 4, thermal source circulating pump 5, outer net pipeline 6 constitute; Wherein thermal source boiler 4, thermal source circulating pump 5, user 1 and adjusting device 2 are utilized 6 series connection of outer net pipeline, constitute closed circle water system; User 1 and adjusting device 2 are in parallel.
A kind of single-tube outer net circulating water system of the present invention is the single cycle pipeline, it goes out to cold from the heat of boiler, and to advance be to be made of a pipe, under the promotion of water pump, after outer net circulating water heats away from boiler, in outer net, take a round and get back to boiler and enter the mouth out and enter boiler, in the process of outer net circulation, each heat exchange station can enter the heat exchanger of heat exchange station according to water intaking pump of the increase in demand extracting high-temperature water from outer net of oneself, after finishing, heat exchange again a water is sent back in the outer net, in the system that does not take heat exchange, the high-temperature water that the water intaking pump extracts from outer net directly mixes the back with user's heating recirculated water and goes into low temperature heating recirculated water supply user heating.The primary side of heat exchanger need increase water water intaking pump one time in the heat exchange station of heat exchange, and the electric control valve of water circulating pump, the mixed coolant-temperature gage of control need be arranged in the system that does not take heat exchange.
In a kind of single-tube outer net circulating water system of the present invention, each heat exchange station has the pump of independently fetching water, outer net circulating water only need guarantee that flow satisfies, there is the lift that can overcome the pipeline on-way resistance to get final product again, reduce the lift and the flow of water pump, also overcome the thermal misadjustment problem in the two-pipe system simultaneously.
