Description
Technical field
The present invention relates to a kind of recovery system more particularly to a kind of recovery systems of flue residue heat.
Background technique
In existing heat power station, heating plant, the temperature of the waste heat in usual flue is probably on 400 to 800 DEG C of left sides
Therefore how the right side utilizes the waste heat in flue gas, it has also become the important topic of energy-saving and emission-reduction protection environment.
In the prior art, heat exchanger usually is set in the flue of heating furnace, is inhaled by the heat-conducting medium in heat exchanger
The heat in flue is received, so that heat-conducting medium is flowed into the heating space in evaporator, carrys out the evaporating space in heating evaporation device
In working medium, become gaseous state, the working medium of gasification is input to steam turbine, externally do work, thus realize flue residue heat is returned
It receives.
However, in the prior art, the heat-conducting medium in heat exchanger is usually using water, and water is under normal pressure usually in its temperature
Degree gasifies when reaching 100 DEG C, in order to make water absorb more heats, usually pressurizes to water.Therefore heat exchanger is just needed
The wall thickness of pipeline for the heat-conducting medium that circulates is sufficiently thick, to guarantee to rupture under an increased pressure.Thus need heavy wall
Pipeline, and the welding condition of pipeline will also correspondingly increase to avoid rupture, to increase cost.
In order to reduce cost, in general, the heat-conducting medium of heat exchanger uses conduction oil, conduction oil can absorb 300 under normal pressure
DEG C to the flue gas heat in the range of 800 DEG C, to can be carried out under normal pressure bigger when the use of conduction oil being heat-conducting medium
Within the temperature range of recovery operation, so there is no need to the circulation ducts of heavy wall, so as to reduce cost.But it is exchanging heat
It in device, due to the physicochemical characteristic of conduction oil, determines that the out temperature difference of heat exchanger is not greater than 60 DEG C, is greater than 60 DEG C in the temperature difference
When, the function that heat exchanger absorbs heat becomes unstable.Therefore, it is difficult to which the fume afterheat in flue is cooled down, can absorb
Waste heat is limited, can not sufficiently recycle heat, it is low to adopt the thermal efficiency.
Summary of the invention
The purpose of the present invention is propose one kind for technological deficiency existing in the prior art and can reduce fume afterheat
Heat recovery in flue gas very in wide temperature range is improved the recovery system for adopting the flue residue heat of the thermal efficiency by temperature.
The following technical scheme is adopted to achieve the purpose of the present invention.
A kind of recovery system of flue residue heat of the invention, comprising: multiple heat exchangers, using conduction oil as heat-conducting medium, edge
The flow direction of flue gas in flue be sequentially mounted in the flue；Multiple evaporators, it is corresponding with multiple heat exchangers
Configuration, the input port of the heating space of each evaporator are connected with the delivery outlet of the corresponding heat exchanger, each described
The delivery outlet of the heating space of evaporator is connected via the first pump with the input port of the corresponding heat exchanger, the multiple evaporation
The evaporating space of device is connected in series；Steam turbine, the output of the evaporating space of the evaporator of the air inlet and series connection of shell
Mouth connection, the exhaust outlet of the shell of the steam turbine pump the evaporating space with the evaporator being connected in series via condenser and second
Input port connection.
In the recovery system of flue residue heat of the invention, sequentially installed on the flow direction of the flue gas of flue it is multiple with
Conduction oil is the heat exchanger of heat-conducting medium, so that substep absorbs the heat in flue gas step by step, sufficiently to utilize to it.Separately
Outside, heat exchanger is connected with corresponding evaporator respectively, i.e. the both ends of the pipeline for having heat-conducting medium of heat exchanger and evaporator
The inlet and outlet of heating space connect, and the series connection of the evaporating space of evaporator.By above-mentioned according to conduction oil substep
The structure for taking the design of heat to be formed, can carry out stepped heating using the heat-conducting medium in heat exchanger as the heating source of evaporator
In the evaporating space of series connection for being supplied to the workmanship working medium of steam turbine, thus by multistage taken from flue gas heat and
Heat recovery in flue gas very in wide temperature range can be improved and adopt the thermal efficiency by the mode that multistage heats working medium.
In addition, the delivery outlet in the recovery system of above-mentioned flue residue heat, preferably in the heating space of the evaporator
On the pipeline connected with the input port of the corresponding heat exchanger, expansion drum is connected in the upstream side of first pump.
Due to conduction oil in heat exchanger dilation, in this way be possible to bubble is mixed into conduction oil, be mixed into bubble
The heat absorption capacity of conduction oil reduces afterwards, to need when using heat exchanger by the gas discharge in heat exchanger.If by leading
Mixed gas is discharged the circulation of hot oil, then takes a long time, and is possible to that gas can not be drained.And in the present invention
In expansion drum is provided on the circulating path of conduction oil, and blow valve is provided on expansion drum, it is swollen in conduction oil in this way
When swollen contraction, the conduction oil in expansion drum can float up and down, the dilation of Lai Pingheng conduction oil, therefore recycle in conduction oil
In the process, the phenomenon that being mixed into air, is not appeared in conduction oil.
In addition, in the recovery system of above-mentioned flue residue heat, preferably in the input port of the heating space of the evaporator
Between delivery outlet, being connected with by the short circuit of the heating space of evaporator and can be such that the input port of heat exchanger is connected to delivery outlet
Bypass with valve.
When heat exchanger absorbs the heat of flue gas in flue, it is possible to will appear the heat exchanger inlet and outlet temperature difference and be greater than 60 DEG C
Situation can thus make the reduced performance of heat exchanger.In the present invention, the inlet and outlet excessive temperature differentials of heat exchanger in order to prevent, if
Set the bypass for making heating space short circuit, that is to say, that when temperature difference of heat exchanger is greater than 60 degree, the valve on bypass is opened,
A part of conduction oil is set directly to be back to heat exchanger not via evaporator, the temperature of heat exchanging device entrance compensates, thus
The temperature difference between heat exchanger inlet and outlet is reduced, thus, it is possible to avoid the occurrence of heat exchanger inlet and outlet excessive temperature differentials and heat exchanger is unstable
Fixed problem.
In addition, being preferably equipped with 3 heat exchangers in the flue in the recovery system of above-mentioned flue residue heat, being located at
