Problems solved by technology

At the same time, the fly ash content in the flue gas after incineration is high, the boiler ash is heavy, and the ash cleaning maintenance period is short
[0007] 2. With the increasing amount of garbage generated and piled up like mountains, the amount of garbage treatment must be effectively increased in order to meet market demand
[0010] Existing gasification incinerators, such as the following two invention patents: Multi-column segmented drive compound domestic waste incinerator (ZL200710092508.9) and two-stage waste incinerator (ZL201010268376.2) Unsolved problems: heat treatment of waste The mode is relatively backward, just drying-burning-burning, the process of solid combustion releasing heat; the thermochemical reaction in the furnace is dominated by oxidation reaction, supplemented by reduction reaction, which is easy to produce secondary pollutants; when garbage is burned in the furnace, the peroxygen coefficient Large, large amount of primary air and secondary air supply, high dust content in flue gas, great impact on heat energy recovery system and flue gas treatment system, easy to accumulate dust, large amount of flue gas, reducing heat conversion efficiency; Without a separate gasification furnace and ember furnace, waste can only be processed in batches, and large-scale continuous gasification and incineration of waste cannot be realized, and the amount of waste treated is small

Embodiment Construction

[0044] see Figure 1 to Figure 6 , which is a preferred embodiment of a double boiler power generation system using waste gasification and incineration of syngas, including a gasification incinerator, a boiler system, and a circulating air supply system.

[0045] see Image 6 , is a mechanical grate type garbage gasification incinerator, including a furnace frame 101, and a feed bin 102, a gasification furnace 103, and an ember furnace 104 that are sequentially arranged on the furnace frame 101 along the feeding direction, and the ember furnace 104 The rear is the slag outlet 116 of the embering furnace 104. The slag outlet 117 is provided on the embering furnace 104. The slag outlet 116 of the embering furnace 104 is located directly below the slag outlet 117 of the embering furnace. The structural sealing effect is good, which can effectively reduce the emission of pollutants. The gasification furnace 103 mainly gasifies the charcoal part of the garbage, and discharges com...

Abstract

The invention discloses a double-boiler power generating system capable of incinerating syngas through garbage gasification, and the double-boiler power generating system is small in heat conversion efficiency loss and higher in heat recovery efficiency. The double-boiler power generating system comprises a steam input pipe, a steam turbine and a power generator. The steam input pipe is connected with the steam input end of the steam turbine. The steam output end of the steam turbine is sequentially connected with a condenser, a water pump, a low-pressure steam water heater, a deaerator, a booster water pump and a high-pressure steam water heater. The heated input end of the low-pressure steam water heater is connected with the water pump, and the heated output end of the low-pressure steam water heater is connected with the deaerator. The heated input end of the high-pressure steam water heater is connected with the booster water pump, and the heated output end of the high-pressure steam water heater is used for outputting water which is used for boilers. The steam turbine is provided with a first steam fetching pipe and a second steam fetching pipe which are used for fetching steam from the steam output end of the steam turbine. The output end of the first steam fetching pipe is connected with the heating input end of the high-pressure steam water heater. The output end of the second steam fetching pipe is connected with the heating input end of the low-pressure steam water heater.

Description

technical field [0001] The invention belongs to the technical field of solid waste incineration treatment, in particular to a double-boiler power generation system utilizing waste gasification to incinerate synthesis gas. Background technique [0002] The existing waste treatment technologies mainly include incineration, sanitary landfill, composting, and waste recycling. Among the conventional waste treatment technologies, incineration has the advantages of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. However, with the continuous improvement of environmental protection requirements at home and abroad, how to strengthen the control of secondary pollution is particularly important. Therefore, waste pyrolysis and gasification incineration technology is gradually pushed to the road of industrial application, ...
