Abstract
The utility model provides a winter refuse heating system for a household refuse incineration power plant, and belongs to the technical field of refuse incineration. The winter refuse heating system for the household refuse incineration power plant comprises a turbine, a condenser, a refuse pit and a lithium bromide heat pump, wherein a driving heat source inlet of the lithium bromide heat pump is connected with the turbine; a driving heat source condensed water outlet of the lithium bromide heat pump is connected with a low-temperature heat source inlet of the lithium bromide heat pump; an inlet of the condenser is connected with a waste steam outlet of the turbine; a condensed water outlet of the condenser is connected with the low-temperature heat source inlet of the lithium bromide heat pump; the lithium bromide heat pump uses high-temperature steam of the turbine as power, and uses driving heat source condensed water of the lithium bromide heat pump and the condensed water of the condenser as a low-temperature heat source, so that high-temperature heating medium water is prepared and enters the refuse pit. With the adoption of the winter refuse heating system for the household refuse incineration power plant, provided by the utility model, the temperature of the refuse pit can be effectively improved, the fermentation conditions of refuse in winter of the household refuse incineration power plant can be improved; the heat value of furnace inlet refuse is provided, so that a boiler is in a household refuse full combustion state in winter.
Description
Technical field
The utility model belongs to garbage incineration technology field, is specially one way of life refuse-burning plant rubbish in winter heating system.
Background technology
At present, MSW Incineration Plant all has the dump pit of storing rubbish, first will be through fermentation in a few days before waste incineration.The object of fermentation is in order to improve the calorific value into stove rubbish, ferments better, and calorific value is higher, more can make boiler combustion stable better with economy.In certain fermentation time, if make the effective rubbish that depends primarily on of rubbish fermentation contain certain moisture and rubbish temperature and want high.
In summer, enter that factory's refuse moisture is large and temperature is high, ferment effect is best, season in spring and autumn still can, the power plant that entirely fires rubbish generally can flameholding at summer spring and autumn boiler.To enter factory's rubbish temperature low winter, rubbish is difficult to fermentation, causes into stove refuse thermal value lowly, affects waste incineration effect.In order to guarantee ferment effect as far as possible, conventionally can only extend the fermentation time of rubbish, but the fermentation time of rubbish is subject to rubbish holds quantitative limitation, cause boiler in the winter time in the situation of clean burn rubbish, can only often throw oil combustion-supporting, guarantee furnace temperature, more than the safety line of 850 ° of C, increases considerably production cost.
Utility model content
The purpose of this utility model is to enter the objective condition such as factory's refuse moisture is few and temperature is low, ferment effect is poor, boiler combustion is unstable winter in order to overcome, provide a kind of winter rubbish heating system, improve rubbish temperature, improve the fermentation condition of rubbish in dump pit, rubbish also can be fermented in the winter time preferably.
The technical scheme that realizes above-mentioned purpose is: one way of life garbage incinerating power plant rubbish in winter heating system, comprise steam turbine, condenser, dump pit and lithium bromide heat pump, the driving heat source import of lithium bromide heat pump is connected with steam turbine, using the high-temperature steam of steam turbine as driving heat source, and the driving heat source condensation-water drain of lithium bromide heat pump is connected with the low-temperature heat source import of lithium bromide heat pump; The import of condenser is connected with the exhaust steam of steam turbine outlet, exhaust steam becomes condensate water after the circulating cooling water cooling of condenser, the condensate water outlet of condenser is connected with the low-temperature heat source import of lithium bromide heat pump, lithium bromide heat pump is usingd the high-temperature steam of steam turbine as power, using the driving heat source condensed water of lithium bromide heat pump and the condensate water of condenser as low-temperature heat source, produce high temperature heat medium water, high temperature heat medium water passes into dump pit, for improving rubbish temperature.
The utility model can effectively improve the temperature in dump pit, improved the fermentation condition of MSW Incineration Plant rubbish in winter, calorific value into stove rubbish is provided, make boiler entirely fire in the winter time in the situation of house refuse, also can reach the safety line above (remaining on 1000 ° of C left and right) that ignition temperature is stabilized in 850 ° of C, reduce boiler and throw oily combustion-supporting number of times (substantially having avoided throwing combustion-supporting oil), reduced production cost.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises steam turbine 1, condenser 2, dump pit 4 and lithium bromide heat pump 3, the driving heat source import of lithium bromide heat pump 3 is connected with steam turbine 1, using the high-temperature steam of steam turbine 1 as driving heat source, and the driving heat source condensation-water drain of lithium bromide heat pump 3 is connected with the low-temperature heat source import of lithium bromide heat pump 3.
The import of condenser 2 is connected with the exhaust steam outlet of steam turbine 1, exhaust steam becomes condensate water after the circulating cooling water cooling of condenser 2, the condensate water outlet of condenser 2 is connected with the low-temperature heat source import of lithium bromide heat pump 3, lithium bromide heat pump 3 is usingd the high-temperature steam of steam turbine 1 as power, using the driving heat source condensed water of lithium bromide heat pump 3 and the condensate water of condenser 2 as low-temperature heat source, produce high temperature heat medium water, high temperature heat medium water passes into dump pit 4, for improving rubbish temperature.
