In the use of the present invention, the valve in the present invention is handled into line label first of all for convenient for description, such as 1 He of attached drawing
1# valves ~ 19# valves in Fig. 2 usually utilize the steam of incineration treatment of garbage generation in normal garbage processing procedure
It generates electricity, but remaining steam carries out condensing recovery processing generally by condenser 2, is handled in condenser 2
In the process, 1# valves, 2# valves, 3# valves, 4# valves, 5# valves, 6# valves, 7# valves, 8# valves, 9# valves are usually opened
, 10# valves, 11# valves, 12# valves, 13# valves, 14# valves, 15# valves, 16# valves, 17# valves in closing system
Door, 18# valves, 19# valves are thus that cold water in cooling column 4 is entered by main pipe 5 of intaking and connect with condenser 2
First side inlet pipeline 7 and second side inlet pipeline 9 enter in condenser 2, and the steam in condenser 2 is carried out solidifyingization processing, is coagulated
To the condensed water in inlet pipeline, condensed water absorbs heat and then water temperature is made to increase heat transfer in vapour device 2, increases the cold of receipts
Condensate, which is discharged and then is entered by first side outlet pipeline 8 and second side outlet pipeline 10, carries out re-circulation refrigeration in return water main pipe 6,
But the heat loss of the raised condensed water of temperature in this process, lead to energy dissipation, using the condensed water heated into
Efficiently using for energy is realized in row heating, during being heated, by 1# valves, the valve of 2# valves, 3# valves
It closes, remaining valve is opened, and the condensed water heated in condenser 2 in this way is by first side outlet pipeline 8 and second side outlet pipeline
10 flow out and then enter in return water main pipe 6, and the water heated in return water main pipe 6 flows into spike heating system 18, works as the winter
When cold season December in season to February, the temperature of needs is not achieved by the condensed water that condenser 2 heats, at this moment just by spike
19# valves in heating system 18 are closed, and the condensed water heated in this way, which enters, carries out heat temperature raising in peak load calorifier 14,
Since the heating of peak load calorifier 14 is heated using 1 one steam pumping of steam turbine, the energy is utilized again in this way, is prevented
The loss for having stopped energy heats condensed water by two sections of peak load calorifiers 14 of spike heating system 18, meets heat
Requirement of the user to temperature, in November in winter and second year March or April, the temperature of the condensed water heated by condenser 2
13# valves, 14# valves, 15# valves, the 16# valves for being sufficient for the heat demand of heat user, therefore being shut off in heating system
Door, 17# valves, 18# valves open 19# valves, and then the condensed water heated is just in charge of by the defeated heat where 19# valves
It is flowed directly into heat user on 13, has saved energy, in actual operating process, can wanted according to the temperature of required heating
It asks, one in spike heating system 18 section of defeated heat with peak load calorifier 14 can be opened be in charge of 13 and also open simultaneously two sections of bands
The water inlet main pipe 5 for having the defeated heat of peak load calorifier 14 to be in charge of 13, and being flowed into from heat user is equipped with pressure gauge 17, passes through pressure
Water pressures in 17 real-time monitoring tubular road of power table carry out increase hydraulic pressure by constant pressure supply water pump 15, and in entire heat supply system
Pipeline in system is equipped with multiple valves and multiple pressure gauges 17 for measuring hydraulic pressure, can monitor water pressures and in time adjustment in real time
Water (flow) direction protects the flow stability of whole system.
The present invention provides a kind of new heat supply mode, i.e., the waste heat generated during domestic garbage burning electricity generation passes through condensing
Heat is transmitted to recirculated water by formula Steam Turbine low-vacuum-operating, for heating.The heat supply mode both realizes domestic rubbish disposal
Innoxious, minimizing, recycling can in not newly-increased power plant unit capacity and in the case of do not increase local pollutant emission
Increase area of heat-supply service, while saving the recirculated cooling water largely lost because of evaporation.
House refuse, which is sent into boiler, burns, and the heat released using burning is by heating in waste heat boiler heating surface
Water, generates the steam with certain pressure and temperature, and main steam collects in a steam main pipe on impulse turbine rotor
Blade rotates, and drives coaxial generator amature rotary electrification；The low temperature and low pressure steam steam exhaust for finishing work(is sent into condenser
Water is condensed by the constantly cooling of closed cycle water, then continues to heat by sending boiler back to again after feed pump raising pressure, carry out past
Multiple cycle.Low temperature and low pressure steam is released in condensation process again after a large amount of latent heats of vaporization (about 2400kJ/kg) are absorbed by recirculated water,
Circulating water temperature increases, and is sent into heating user by circulation pump of heat-supply network by water supply line, the cold water come out from heating user
（That is heating water return）The steam exhaust of condenser cooling steam turbine discharge is squeezed into through water circulating pump again, in cycles.
