Abstract
The invention relates to a system for heating and unfreezing a winter dump pit of a garbage incineration power plant. The system comprises a continuous blow-down flash tank, an intermittent blow-down flash tank, a blow-down cooling tank and the dump pit, wherein a continuous blow-down hole of a waste heat boiler is accessed to an inlet of the continuous blow-down flash tank; a dewatering hoe of the continuous blow-down flash tank and an intermittent blow-down hole of the waste heat boiler are connected to an inlet of the intermittent blow-down flash tank through a pipeline; an outlet drain of the intermittent blow-down flash tank is divided into three branch pipes through a tee joint, is separately connected to an inlet of the blow-down cooling tank and an unloading hall side of the dump pit, is connected to the blow-down cooling tank and the dump pit; and valves are arranged on all branch pipes. The system effectively heats and unfreezes introduced low-temperature garbage and improves the fermentation effect of the winter dump pit, so that a heat value of garbage in a furnace is increased, an auxiliary combustion system is avoided, and winter operation cost of the power plant is greatly reduced.
Description
Technical field
The invention belongs to waste incineration and generating electricity technical field, specially a kind of garbage incineration power plant winter dump pit heating solution
Jelly system.
Background technology
After rubbish is transported into garbage incineration power plant, dump pit storage need to be put into and fermented a couple of days, to improve the heat into stove rubbish
Value.The essence of rubbish fermentation be the vital movement for relying on microorganism improveing the process of house refuse, therefore, the fermentation speed of rubbish
Rate is largely dependent on the active degree of microorganism.Research shows, junk-heap body temperature at 30-65 DEG C, mesophilic bacteria group and
High-temperature group is in active state, and sweat is very fast, if ambient temperature is low, heap temperature is also decreased, sweat
It is slower.
In general, when spring, summer, autumn, in trash repository, temperature is higher, and rubbish fermentation effect is good, enters stove refuse thermal value height,
Flameholding in stove.But in the winter time, especially in northern China, admission rubbish temperature is very low, rubbish freezes even entrainment ice and snow,
Totally unfavorable to sweat, under same fermentation time, the calorific value of rubbish is reduced.Rubbish can only be extended in this case generally
Fermentation time, but fermentation time limited by dump pit reserves again, can only finally put into combustion-supporting system lower heat of combustion rubbish,
So as to operation cost is significantly increased, also it is unfavorable for the generation of bioxin and other pollutant is controlled in burning process.
The content of the invention
Present invention aim at providing a kind of dump pit heating system suitable for garbage incineration power plant, entered with tackling winter
Factory's temperature garbage even freezes the situation for affecting rubbish fermentation in dump pit.
The technical scheme is that：A kind of garbage incineration power plant winter dump pit heats defrosting system, including continuous row
Dirty flash vessel, regular unloading container, blowdown cooling tank and dump pit；The continuous blowdown of waste heat boiler accesses the continuous blowdown
Flash vessel entrance, drain port and the waste heat boiler periodical blowdown of continuous blowdown flash tank are connected to periodical blowdown expansion by pipeline
Container entrance, regular unloading container outlet is hydrophobic to be divided into three road arms by a threeway, is respectively connected to blowdown cooling tank and enters
Mouthful and dump pit discharging hall side, be connected to blowdown cooling tank and dump pit, be provided with valve on all arms.When spring, summer, autumn
In season, when dump pit temperature is higher, the valve opening being connected at blowdown cooling tank arm is connected to the valve at dump pit arm and closes
Close, after waste heat boiler continuous blowdown accesses continuous blowdown flash tank blood pressure lowering flash distillation, its hydrophobic access regular unloading container is and remaining
The blood pressure lowering flash distillation together of heat boiler periodical blowdown, the hydrophobic environment temperature picked out by regular unloading container are connected to blowdown drop when higher
Wen Chi；When winter, dump pit temperature was relatively low, the valve closing being connected at blowdown cooling tank arm is connected at dump pit arm
Valve opening, regular unloading container is hydrophobic to access dump pit discharging hall side, just pours into for heating and thawing low in hole
Warm rubbish.
The steam that the continuous blowdown flash tank is flashed off is connected to deaerating type of cycles UTILIZATION OF VESIDUAL HEAT IN, regular unloading container flash distillation
The steam discharging for going out.
Present invention has the advantages that：Simple system, design, implementation cost are low, reliable, it is possible to use house refuse is burnt
Burn the low-grade exhaust heat in power generation thermodynamic system and improve local temperature of the dump pit in discharging hall side, so as to effectively heating and
The low temperature rubbish of defrosting admission, improves winter dump pit ferment effect, and then improves into stove refuse thermal value, it is to avoid input auxiliary combustion
Burning system, is greatly reduced power station winter operation cost.
Description of the drawings
Fig. 1 is the system schematic of the present invention.
Specific embodiment
As shown in figure 1, a kind of dump pit heating system suitable for garbage incineration power plant of the present invention, including continuous blowdown expansion
Container, regular unloading container, blowdown cooling tank and dump pit.The continuous blowdown of waste heat boiler accesses continuous blowdown flash tank 1
Entrance, drain port and the waste heat boiler periodical blowdown of continuous blowdown flash tank 1 are connected to regular unloading container 2 by pipeline
Entrance, regular unloading container 2 export hydrophobic by a threeway, are respectively connected to unloading for 3 entrance of blowdown cooling tank and dump pit 4
Material hall side, is connected on the arm of blowdown cooling tank 3 and dump pit 4 and arranges valve.When spring, summer, autumn, dump pit temperature is higher
When, the valve opening being connected at blowdown cooling tank arm, the valve closing being connected at 4 arm of dump pit, regular unloading container
Hydrophobic access blowdown cooling tank 3；When winter, dump pit temperature was relatively low, the valve closing being connected at blowdown cooling tank arm connects
Valve opening to 4 arm of dump pit, regular unloading container is hydrophobic to access dump pit 4 discharging hall side, for heating and
The low temperature rubbish that defrosting is just poured in hole.For simplified system and reduces cost, the hydrophobic employing of regular unloading container 2 is from manifold
Formula accesses dump pit 4, therefore the processing technique of its connecting pipe and arrangement trend, and the access port position of dump pit 4 needs root
Carry out optimizing after water force according to practical situation.
