Detailed description of the invention
In Fig. 1, municipal administration heat distribution pipeline is divided into two set blood circulation after entering consumer heat inlet, low district blood circulation and high district blood circulation, the operational process of high district blood circulation is: set the aperture of constant flow control valve (16), reach the metered flow value needed for high district blood circulation, open speed change pressurization cycle water pump (5) and two-stage supercharging water circulating pump (8) simultaneously, the when that two-stage supercharging water circulating pump (8) reaching rated speed, automatic speed governing device can regulate the rotating speed of speed change pressurization cycle water pump (5), until the pressure transducer (10) being arranged on high district top layer measures pressure reaches top layer desirable pressure value, and stablize top layer desirable pressure value by being automatically adjusted speed change pressurization cycle water pump (5) rotating speed.
High district backwater drives hydrogenerator (14) to reach stabilized (steady-state) speed, hydrogenerator can export the electric energy of rated power by stable-pressure device, hydrogenerator is greatly reduced high district pressure of return water, unnecessary pressure is consumed by constant flow control valve (16), Shi Gao district return pipe (22) force value is identical with low district return pipe force value, and system reaches steady operational status.
After high district blood circulation is stable, switch to hydrogenerator (14) to power the mains-supplied of two-stage supercharging water circulating pump (8), reduce the high-rise direct-connected total power consumption of heating cycle system.
When system needs variable-flow operation, the flow first setting constant flow control valve (16) reaches target flow value, hydrogenerator (14) opens the number of units of coupling according to target flow value size, the generated output that output is corresponding, number of units or generated output that two-stage supercharging water circulating pump (8) runs according to hydrogenerator (14) adjust rotating speed automatically, make two-stage supercharging water circulating pump (8) output generated output less than hydrogenerator (14), speed change pressurization cycle water pump (5) stablizes high district top layer pressure by pressure transducer (10) and automatic speed governing device.
When speed change pressurization cycle water pump (5) breaks down out of service, check-valves (7) cuts out, pressure between speed change pressurization cycle water pump (5) outlet and check-valves (7) is greatly reduced, approximate consumer heat inlet pressure of supply water value, gather under speed change pressurization cycle water pump (5) normal operation due to connecting pipe (17) is high pressure, when speed change pressurization cycle water pump (5) breaks down out of service, what connecting pipe (17) gathered is low pressure, the flap making block device (18) internal produces out-of-balance force, flap will be closed under the active force of spring force, prevent high district backwater from flowing into low district return pipe.When speed change pressurization cycle water pump (5) is fixed a breakdown and is continued to run with or switch to standby speed change pressurization cycle water pump (6) to run, connecting pipe (17) gathers high pressure, overcome block device (18) contained spring elastic force so that block device (18) internal flap is opened, and high district blood circulation is properly functioning.
When block device (18) breaks down, if speed change pressurization cycle water pump (5) breaks down out of service, block device (18) will be unable to block the high pressure backwater in high district, high pressure backwater will enter expansion drum (19) decompression, if still superpressure, then relief valve (21) is opened, superpressure water in high district return pipe (22) is entered sluicing pond (20), until high district pressure of return water is less than safety valve setting force value, prevent high pressure backwater from flowing into low district return pipe, ensure that low district blood circulation is properly functioning.
