Therefore, in order to achieve harmlessness, ordinary waste incineration power generation systems need to adopt additional treatment processes for leachate, flue gas, slag, fly ash, etc., or outsource treatment and disposal, which is extremely expensive
Taking fly ash as an example, the processing cost per ton of fly ash can reach up to 5,000 yuan / t, plus the steam consumption of heating flue gas before SCR (millions of yuan per year), the investment and operating costs of soot blowing on each heating surface , heating surface anti-corrosion design and overhaul inspection costs, etc., resulting in high operating costs of waste incineration power plants

Embodiment 1
[0028] Such as figure 1 As shown, a 1-input and 2-outlet waste incineration power generation system includes an incinerator 1, a first flue 2, a second flue 5, a third flue 6, a high-temperature SCR system 9, and a horizontal flue 10 connected in sequence. , heat exchanger 14, induced draft fan 16 and chimney 17. The inner wall of the first flue 2 is castable, and a high-temperature dust collector 3 with a temperature resistance ≥ 1000° C. is installed inside. The top of the first flue 2 is provided with a ceiling 4 protected by a pouring material, and an SNCR system is provided on the ceiling 4, and the ceiling 4 is connected to the smoke inlet of the submerged evaporator 8 through a smoke branch valve 7. The flue gas outlet of the submerged evaporator 8 is connected with the flue gas inlet of the third flue 6 . The heating surface of the horizontal flue 10 is provided with a steam pipeline, and the steam outlet of the steam pipeline is connected to a steam turbine 11, and ...

The invention discloses a one-inlet and two-outlet waste incineration power generation system and a process thereof, and belongs to the technical field of waste incineration power generation. In the system, a high-temperature dust remover is arranged in a first flue, a ceiling is arranged at the top of the first flue, the ceiling is connected with a flue gas inlet of an immersed evaporator through a flue gas branch valve, and a flue gas outlet of the ceiling is connected with a flue gas inlet of a third flue; a steam pipeline is arranged on the heating surface of the horizontal flue, a steam outlet of the steam pipeline is connected with a turbine, and the turbine is connected with a generator; the heated surface of the horizontal flue is connected with a cooled flue gas inlet of the heat exchanger, a cooled flue gas outlet of the heat exchanger is connected with a cooled flue gas inlet of the wet deacidification tower, a deacidification flue gas outlet of the wet deacidification tower is connected with a deacidification flue gas inlet of the heat exchanger, and a deacidification flue gas outlet of the heat exchanger is connected with a flue gas inlet of the induced draft fan. According to the invention, through process reform, a fly ash and leachate treatment process is omitted, the investment cost is saved, and the economic benefit is improved.
Description
technical field [0001] The invention belongs to the technical field of waste incineration power generation, and specifically relates to a 1-in, 2-out waste incineration power generation system and its technology. Background technique [0002] Ordinary waste incineration power generation system generally refers to a 1-in 4-out waste incineration power generation system, that is, 1 type of waste - garbage in, 4 types of waste - leachate, flue gas, slag, fly ash out of waste reduction processing method. Therefore, in order to achieve harmlessness, ordinary waste incineration power generation systems also need to adopt additional treatment processes for leachate, flue gas, slag, fly ash, etc., or outsource treatment and disposal, which is extremely expensive. Taking fly ash as an example, the processing cost per ton of fly ash can reach up to 5,000 yuan / t, plus the steam consumption of heating flue gas before SCR (millions of yuan per year), the investment and operating costs...
