Fossil-fuel power generation system assisted by waste incineration

1. A fossil-fuel power generation system assisted by waste incineration, comprising a waste incineration subsystem and a fossil-fuel power generation subsystem; wherein:

said waste incineration subsystem comprises a waste incinerator and said fossil-fuel power generation subsystem comprises a main boiler;

a flue gas channel is provided between a furnace of said waste incinerator and said main boiler; and said waste incinerator incinerates waste and generates flue gas which enters said main boiler through said flue gas channel; and

said flue gas channel is lined with fire-resistant materials;

the fossil-fuel power generation system further comprises a control device, wherein: said control device comprises a switch component for controlling said waste incineration subsystem to enter or withdraw from said fossil-fuel power generation subsystem in real time; and said control device is further for controlling a feeding frequency and a total ventilation amount of said waste incineration subsystem;

said waste incineration subsystem further comprises a storage chamber, an inputting mechanism and a feeding mechanism, wherein:

said storage chamber is for sending the waste to said furnace;

said inputting mechanism comprises a hopper, a wings flap, a flap box and an inputting channel leading to said furnace, wherein:

said hopper has a steel-plate structure and hangs at an outlet of said storage chamber;

said wings flap, for preventing air from entering said furnace of said waste incinerator when said hopper is short of waste, comprises a hollow shaft, a bearing neck, a transmission lever, a radial joint coupler and a hydraulic cylinder;

said flap box contains said wings flap, and connects said hopper and said inputting channel; and

said inputting channel has an inlet sleeved with said flap box and an outlet connected with said furnace; said inputting channel is further provided with a water injection connection sleeve and a drainage connection sleeve; and

said feeding mechanism is a mechanical non-stop feeding mechanism, comprising two pounder-type feeding push-rods with a hydraulic synchronous movement, a connecting rod, a universal joint, a sliding plate, a sealing panel, a feeding rail made of steel plates and steel brackets, a beam located above an inlet of said furnace and a coaming with a protective lining.

2. The fossil-fuel power generation system assisted by waste incineration, as recited in claim 1 , wherein said inputting mechanism further comprises a compensator which is located between said flap box and said inputting channel.

3. The fossil-fuel power generation system assisted by waste incineration, as recited in claim 1 , wherein said waste incinerator has a pushing-type grate structure, comprising a grate, a holder for said grate, a power device and a grate driving component; wherein:

said grate, located below said furnace, comprises orderly arranged movable grate strips and fixed grate strips, wherein a row of said fixed grate strips and a row of said movable grate strips are staggered successively;

said holder for said grate is located below said grate for supporting said movable grate strips and said fixed grate strips;

said power device, for supplying hydraulic power for said whole waste incinerator, comprises a hydraulic unit, a reversing valve, a relief valve, a pressure gauge, a pressure switch and an oil tank; and

said grate driving component comprises a plurality of driving motors and corresponding connection pipelines.

4. The fossil-fuel power generation system assisted by waste incineration, as recited in claim 3 , wherein said waste incinerator further comprises a cooling mechanism which has a peripheral protective sleeve and is mounted on a sidewall of a whole combustion zone of said furnace.

5. The fossil-fuel power generation system assisted by waste incineration, as recited in claim 3 , wherein said waste incinerator further comprises two sets of ignition and combustion burners which are symmetrically mounted on two sidewalls of said furnace.

6. The fossil-fuel power generation system assisted by waste incineration, as recited in claim 3 , wherein said waste incinerator further comprises a slag discharging and soot cleaning equipment which comprises an ash hopper, a scraping-rake-type transporter, an ash hopper fastener and a sliding slot; wherein:

said ash hopper for collecting fallen ash is located at a bottom of said grate;

said scraping-rake-type transporter is for cleaning said fallen ash in said ash hopper by wetting;

said ash hopper fastener for closing a discharging outlet of said ash hopper is located below said ash hopper; and

said sliding slot connects said ash hopper and said scraping-rake-type transporter.
