Description

Technical Field

[0001] The utility model belongs to the technical field of incinerator power generation, and specifically relates to a power generation transformation device for an incinerator directly mixing and burning wet sludge. Background Art

[0002] The technical background of the power generation equipment using wet sludge in an incinerator is mainly that wet sludge is a common solid waste that contains a large amount of organic matter and potential beneficial resources, such as incompletely burned organic matter and heat. However, due to its high water content, the incineration process of wet sludge has always been a challenge. Traditional incinerator designs may not be able to effectively handle wet sludge with high water content, because the moisture will dilute the oxygen content in the incineration chamber and hinder the combustion process. At the same time, the generated water vapor and other gases may also affect the heat exchange efficiency in the incinerator. The problems with the existing incinerator power generation equipment using sludge are mainly due to the high water content of the sludge and the difficulty of internal gas entering, resulting in low sludge combustion efficiency. Utility Model Content

[0003] In order to overcome the problem of low sludge combustion efficiency in existing incinerators for sludge power generation equipment, the sludge has high water content and internal gas is difficult to enter.

[0004] The technical solution of the utility model is: an incinerator directly mixed with wet sludge to generate electricity transformation equipment, including an incineration component, a heat exchange component, and an air waste heat component; the air waste heat component is arranged inside the incineration component; a heat exchange component is arranged on one side of the incineration component; the incineration component includes an incinerator, an ash discharge port, a gas nozzle, and a sludge combustion cage.

[0005] Preferably, air is blown into the heating sleeve from the outside through the blast air inlet, and the heating sleeve is heated by the external hot air so that the blown air is preheated and then introduced into the sludge combustion cage along the ventilation hook pipe, so that the sludge inside the sludge combustion cage is heated and air-dried. At the same time, the gas nozzle is ignited to ignite and burn the sludge combustion cage, and the heat emitted by the sludge combustion cage is used to further preheat the air introduced into the heating sleeve, thereby effectively improving the drying speed of the sludge in the sludge combustion cage and increasing its internal oxygen supply, thereby greatly improving the sludge combustion efficiency, and solving the problem of low sludge combustion efficiency caused by the existing incinerator burning sludge power generation equipment because the sludge has a high water content and the internal gas is difficult to enter.

[0006] Preferably, the lower end port of the incinerator is provided with an ash discharge port, and the ash discharge port is integrally formed with the incinerator.

[0007] Preferably, a gas nozzle is provided on one side of the incinerator, and an output end of the gas nozzle is arranged inside the incinerator.

[0008] Preferably, the heat exchange component includes a flue gas heat exchange chamber, a hot water exchange pipe, and a flue gas exhaust pipe; a flue gas heat exchange chamber is arranged on one side of the incinerator, and the flue gas heat exchange chamber is sealed and connected to the incinerator flange; a hot water exchange pipe is arranged inside the flue gas heat exchange chamber, and both ends of the hot water exchange pipe are connected to the input and output pipelines of an external water pump.

The flue gas extraction pipe extracts the high-temperature flue gas in the incinerator for discharge. At this time, the high-temperature flue gas passes through the water exchange water pipe to heat the water introduced into the interior to near the boiling point, thereby effectively improving the utilization rate of the waste heat of the exhaust gas and flue gas. Finally, the hot water near the boiling point is introduced into the power generation boiler for evaporation, and finally the steam is introduced into the turbine steam engine to drive the turbine blades to generate electricity.

[0010] Preferably, the air waste heat component includes an air blast inlet, a heating sleeve, and a ventilation hook pipe; the interior of the incinerator is provided with an air blast inlet; the external fixed sleeve of the air blast inlet is provided with a heating sleeve; the lower end of the heating sleeve is provided with a ventilation hook pipe, and the ventilation hook pipe, the heating sleeve, and the air blast inlet are through-connected.

[0011] Preferably, a sludge combustion cage is provided at the lower end of the ventilation hook pipe, and the ventilation hook pipe is hung and connected to the sludge combustion cage, and the output end port of the ventilation hook pipe is arranged inside the sludge combustion cage, and air is blown into the heating sleeve from the outside through the blast air inlet, and the heating sleeve is heated by the external hot air so that the blown air is preheated and then introduced into the sludge combustion cage along the ventilation hook pipe, so that the sludge inside the sludge combustion cage is heated and air-dried, and at the same time, the gas nozzle is ignited to ignite and burn the sludge combustion cage, and the heat emitted by the sludge combustion cage is used to further preheat the air introduced into the heating sleeve, thereby effectively improving the drying speed of the sludge in the sludge combustion cage and increasing its internal oxygen supply, thereby greatly improving the sludge combustion efficiency.

[0012] Beneficial effects of the utility model:

[0014] Through the setting of heat exchange components; the flue gas exhaust pipe extracts the high-temperature flue gas in the incinerator and discharges it outside. At this time, the high-temperature flue gas passes through the hot water exchange pipe to heat the water entering the inside to near the boiling point, thereby effectively improving the utilization rate of the waste heat of the exhaust gas and flue gas. Finally, the hot water near the boiling point is introduced into the power generation boiler for evaporation, and finally the steam is introduced into the turbine steam engine to drive the turbine blades to generate electricity.
