The device comprises a garbage pit, a percolate tank which is arranged below the garbage pit and is matched with the garbage pit, a percolate heating system and a percolate spraying pipeline, wherein the percolate spraying pipeline is horizontally arranged all around in the garbage pit; a plurality of spraying holes are uniformly distributed in one side, which faces garbage, of the percolate spraying pipeline; and percolate in the percolate tank is heated by the percolate heating system and then is conveyed to the percolate spraying pipeline so as to heat the garbage in the garbage pit. With the adoption of the percolate heating system provided by the utility model, garbage is heated to raise the temperature so as to improve the fermentation condition of the garbage of the household garbage incineration power plant in winter and improve the heat value of the garbage in a boiler, so that the combustion temperature of the boiler under the condition of full-combustion household garbage in winter can be stabilized to be above a safety line of 850 DEG C.
Description
Technical field
The utility model belongs to garbage incineration technology field, is specially a kind of device that regulates MSW Incineration Plant rubbish fermentation in winter temperature.
Background technology
At present, MSW Incineration Plant all has the dump pit of storing rubbish, and before waste incineration, first through fermentation in a few days, 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 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, 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 temperature low winter, affect the burning effect of rubbish.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 dump pit holds quantitative limitation, cause boiler in the winter time in the situation of clean burn rubbish, only have frequent throwing oil combustion-supporting, guarantee furnace temperature, more than the safety line of 850 ℃, significantly increases production cost.
Utility model content
The purpose of this utility model is to enter in order to overcome that factory's rubbish refuse moisture is few and temperature is low, ferment effect is poor, the unsettled objective condition of boiler combustion winter, the utility model provides a kind of device that regulates rubbish fermentation temperature in winter, ooze drop liquid by sending into high temperature to freezing rubbish in dump pit, improve the fermentation condition of rubbish at dump pit to rubbish temperature raising, rubbish also can be fermented in the winter time preferably.
The technical scheme that realizes above-mentioned purpose is: a kind of device that regulates MSW Incineration Plant rubbish fermentation in winter temperature, it is characterized in that: comprise dump pit, be arranged on dump pit below and the diafiltration liquid pool that is used in conjunction with dump pit, percolate heating system and percolate spray piping, described percolate spray piping horizontally disposed in the hole of dump pit surrounding, percolate spray piping is evenly equipped with some spray orifices towards a side of rubbish, the input of percolate heating system is connected with diafiltration liquid pool, the output of percolate heating system is connected with percolate spray piping, percolate in diafiltration liquid pool is sent into percolate spray piping after heating by percolate heating system, rubbish in dump pit is heated.
Between spray orifice on described percolate spray piping, be the calabash shaped being interconnected, be conducive to prevent obstruction and the cleaning of spout,
The input of described percolate spray piping is connected with compressed air input pipe, and the spray sky of percolate shower purges by the compressed air in compressed air hose while obstruction.
Described percolate heating system comprises heat exchanger and steam turbine, the refrigerant entrance point of described heat exchanger is connected with diafiltration liquid pool by water circulating pump, the entrance point of water circulating pump is connected with diafiltration liquid pool, the port of export of water circulating pump is connected with heat exchanger, the refrigerant exit end of heat exchanger is connected with percolate spray piping, the heating agent entrance point of heat exchanger is connected with steam turbine, and the heating agent port of export of heat exchanger is provided with out hydraulic control valve.
Described water circulating pump comprises two water pumps of a preparation and a use.
In described diafiltration liquid pool, be provided with temperature sensor, temperature sensor is controlled the openings of sizes that hydraulic control valve of the heating agent port of export of heat exchanger by the temperature information of percolate in the diafiltration liquid pool gathering, control the quantity of steam of heat exchanger heating agent entrance point, guarantee the thermal effect that is subject to of rubbish.
The percolate pipeline that the utility model is arranged in dump pit surrounding adopts and drenches nozzle type, and high temperature percolate is contacted more fully with rubbish, guarantees the being heated evenly property of rubbish.
In the dump pit of garbage incinerating power plant, due to winter cold make into factory's rubbish temperature low, cannot meet the temperature conditions of crude waste fermentation, cause into stove refuse thermal value lower, affect waste incineration effect, spray into high temperature percolate to rubbish heap in this way, from outside to inside giving rubbish temperature raising, improve the fermentation condition of rubbish at dump pit, rubbish also can be fermented in the winter time preferably.
The rubbish heating system that adopts the utility model to provide, by heating temperature raising to rubbish, improve the fermentation condition of MSW Incineration Plant rubbish in winter, improve the calorific value that enters stove rubbish, boiler is fired in the situation of house refuse in the winter time entirely, also can reach the safety line above (remaining on 1000 ℃ of left and right) that ignition temperature is stabilized in 850 ℃, reduce boiler and throw oily combustion-supporting number of times (substantially not throwing oil combustion-supporting), reduce production cost.
