Brief description of the drawings
Fig. 1 is the overall schematic of the distributed mixing heating system of the defeated single tube of the length described in the application.
Detailed description of the invention
As shown in Figure 1, the invention provides the distributed mixing heating system of a kind of long defeated single tube, comprise single thermal source 1, single tube heat supply network and thermal substation, wherein thermal substation comprises energy source station 2, between for station 3, one in direct-furnish station 4 and large temperature difference thermal substation 5 and/or multiple, the outlet of single thermal source is connected with single tube heat supply network, thermal substation is serially connected on single tube heat supply network, wherein between the entrance and exit of energy source station 2, be connected with and cross over pipe and be provided with valve 11 on leap pipe, between cross over pipe and be provided with valve crossing on pipe for being also connected with between 3 the entrance and exit of station, the entrance pipe of thermal substation is provided with independent loops water pump 6, on single tube heat supply network, be also serially connected with heat supply network main circulation pump 8, the outlet of heat supply network main circulation pump 8 is connected with the water return outlet of single thermal source.
On single tube heat supply network, be also serially connected with filter 7, the entrance of filter 7 is connected with the outlet of thermal substation, and the outlet of filter is connected with the entrance of heat supply network main circulation pump 8.
Single tube heat supply network is also connected with small pump 9 and water supply tank 10 by valve 13.
Single thermal source is a kind of and/or multiple in steam power plant, heating boiler, machine waste heat recovery.
The entrance pipe of thermal substation is provided with independent loops water pump 6, and the entrance of independent loops water pump 6 and/or outlet are connected with control valve 12.
Direct-furnish station 4 is multiple, after multiple direct-furnish station 4 is in parallel, is serially connected on single tube heat supply network again.
Large temperature difference thermal substation 5 is one or more, between large temperature difference thermal substation 5 or after in parallel between large temperature difference thermal substation and one or more direct-furnish station, is serially connected on single tube heat supply network again.
Single thermal source is a kind of and/or multiple in steam power plant, heating boiler, machine waste heat recovery, for system provides high-temperature-hot-water, by single tube heat supply network, delivery is arrived to thermal substation, after thermal substation and the heat exchange of user's side, hot water returns single tube heat supply network, last hot water enters thermal source water return outlet by heat supply network main circulation pump, is admitted to thermal source and again heats, and completes the circulation of hot water in heat supply network; Each thermal substation can pass through independent loops water pump, control valve, leap pipe and cross over independent control of valve realization on pipe.
Water supply tank provides moisturizing by small pump to single tube heat supply network.
Independent control procedures taking a confession station 3 as example explanation thermal substation.In the time that the valve 11 on leap pipe is closed or regulates, the control valve 12 that the porch of independent loops water pump 6 connects is opened, between the high-temperature-hot-water that carrys out self-heat power enters by control valve 12 and independent loops water pump 6 for station 3, in a confession station 3, carry out heat exchange with user's side, hot water release heat is got back to single tube heat supply network later again.User's side obtains after heat, for user provides heat supply hot water.When breaking down when needing maintenance or provide user's side of heat not need heat supply for station 3 for station 3, the valve 11 of crossing on pipe is opened, the control valve 12 that the porch of independent loops water pump 6 connects cuts out, and hot water is managed circulation by leap, supplies station 3 heat exchange between not entering.
The independent control procedure of energy source station 2 and a confession station 3 are substantially similar.
The independent control valve 12 being directly connected with its porch by independent loops water pump 6 of controlling of direct-furnish station 4 and large temperature difference thermal substation 5 is realized, and opens or closes control valve 12 and controls whether hot water enters direct-furnish station 4 and large temperature difference thermal substation 5 carries out heat exchange.
Independent loops water pump 6 can also regulate respectively flow and the flow velocity of the hot water that enters thermal substation.
Single-main distribution is to have cancelled water return pipeline with tradition for the difference of backwater two-pipe system, utilizes single water supply line to be together in series or parallel for each thermal substation in thermal region and each hot user, forms distributed mixing heating system.In this system, pipeline no longer progressively attenuates with Design cooling load situation, drag losses and changes in flow rate, but is made up of the single branch network of pipes that waits caliber (waiting flow) water supply line to be circular layout.Heat supply network sigle-pipe concurrent-flow is made up of single tube, leap pipe, all kinds of valve member, expansion bend etc., saves tubing than two-pipe system, and minimizing is invested, system is simple, easy for installation, takes up an area less.
Because thermal substation is all installed independent loops water pump 6, therefore can not consider the resistance loss of sewage heat exchanger of traditional heat supply network in design, in single-main distribution heat supply network main circulation pump 8 design selections, only consider line loss, two factors of the heating districts physical features discrepancy in elevation, ensure the mobile satisfied circulation of hot net water, can realize farthest the heat-net-pipeline of 100 kilometers, be applicable to long distance and carry, and reduce heating network operation cost.Thermal substation is installed independent loops water pump 6 and is crossed over pipe, control valve, improve thermal substation self-adjusting ability, the horizontal hydraulic misadjustment problem of existing heating system, planning load and actual load are effectively solved, at developing mismatch problem, realize systems of distributed heating systems, user's effluent amount, pressure are by each hot source point self-regulation.
Single tube heat network system water supply maximum temperature can reach 190 DEG C, improves supply water temperature, can increase heat supply network back-up capability, and System Expansion is good, reduces heat supply network caliber simultaneously, reduces initial investment, strong and municipal heating systems long-term plan and urban construction and development.
Between being not only to have, the difference of single-main distribution thermal substation and traditional heat supply network supplies station, direct-furnish station, energy source station and large temperature difference thermal substation are also introduced, single-main distribution has realized direct-furnish, a heating network system is mixed application, utilize between energy source station, tradition and connect, combine for the difference of station, traditional direct-furnish station, large temperature difference thermal substation, effectively reduce single-main distribution return water temperature, thereby raising heat transfer temperature difference, promote pipe network conveying capacity, and the hot source point (steam power plant etc.) that has waste heat recovery apparatus is improved to its waste heat recovery ability.
One pipe heating system is to adopt the single branch network of pipes that waits caliber (waiting flow) water supply line to circularize layout.Heat supply network sigle-pipe concurrent-flow is made up of one-pipe, leap pipe, all kinds of valve member, expansion bend etc., and its heat network system is simple in structure; Each thermal substation is installed independent loops water pump 6 and is crossed over pipe, control valve, and thermal substation self-adjusting ability is high, for the operation of many thermals source common network provides the foundation.
