Product Desciption

MSW Municipal Solid Waste to Energy Garbage Power Plant

Introduction of Incineration System Technology
1. Garbage acceptance and storage
Municipal waste is transported into the factory by a special garbage truck, and then automatically weighed by a truck scale, and then enters the unloading hall of the joint factory (the weighbridge room has the functions of weighing, metering, transmission, printing, and data processing). The garbage bin is a large cement pit with anti-seepage and anti-corrosion, with a filtrate drainage ditch in the middle. There are two garbage pits, which can store garbage disposal capacity for 10-15 days in total. The incinerator is arranged in the middle position. On both sides of the incinerator, garbage pits, garbage unloading platforms and sorting equipment are set up respectively. The garbage unloading platform adopts an outdoor type with gates. The garbage discharge channel is close to the garbage storage pit. The garbage truck dumps garbage into the garbage pit from the outside. At the same time, an air curtain is set at the garbage door to prevent the odor from leaking. The unloading platform is equipped with a dedicated garbage transport truck entrance and exit. The two unloading halls are each equipped with 3 garbage truck unloading doors. There are traffic lights in the lobby and the crane control room to indicate the status of the door opening and closing. The platform has enough area to meet the driving, U-turn and unloading of the largest garbage transfer vehicle without affecting the operations of other vehicles. In order for the garbage truck driver to accurately aim the garbage at the garbage door and unload the garbage into the garbage pool without causing the truck to turn into the garbage bin, there is a white zebra crossing sign in front of each door, and a car stop is set near the door. Set up water hydrants to clean the ground around the garbage unloading platform, maintain the slope of the ground and set up drainage ditches in the direction of the garbage storage pit to collect and discharge sewage, and send it to the collection tank together with the leachate collected in the garbage storage pit. The section of the garbage storage pit is shown in the figure.
2. Garbage feeding system
One orange flap grab crane is set above each garbage pool. The crane has a lifting capacity of 5t, and the rail top elevation is 19.5m. The crane is equipped with a weighing device, and has sub-system measurement, pre-alarm, overload protection, anti-sway, anti-tilt, self-positioning, anti-collision and other functions. It can record and can In the crane control room, display statistics and record the various parameters of the feeding. The crane is equipped with manual operating system and automatic operating system switching port. The crane can be used for charging the incinerator and mixing, dumping, transporting, stirring the garbage, etc., and stacking them in the predetermined area in order to ensure the uniform and stable combustion of the components of the garbage into the furnace. The incinerator is equipped with 5 garbage inlets, which are evenly distributed in the incinerator for a week. Each garbage inlet corresponds to a two-stage screw feeder, and the garbage is fed into the furnace in the order of "grab → garbage hopper → first-stage screw feeder → second-stage screw feeder → incinerator".
In view of the harsh environment in the garbage pool, the operation of the grab crane is remotely controlled by the driver in the cab, which is set at an elevation of 18m. The operator can conveniently observe the conditions in the garbage storage pit. The operator is equipped with a display on the upper front and connected with the camera device above the feeding hopper to make it conducive to operation. The crane adopts automatic control, which can reduce the labor of the operator, and it can also be switched to manual control. The grab crane is equipped with a metering device, which transmits the amount of garbage loaded to the control room for recording. The cab and the central control room are arranged separately, and the central control room is located on the 9.5m level, which is convenient for controlling all equipment.

4. Waste heat boiler system
The waste heat boiler is a vertical boiler specially made for this project. The flue gas flows through the following heating surfaces of the waste heat boiler: superheater, evaporator, and economizer. The tube bundles of the superheater and the economizer are cleaned by an effective dust removal device. In order to avoid low-temperature corrosion of the heating surface pipes, the flue gas temperature at the outlet of the economizer is reduced to about 180°C. The waste heat boiler steams 43 tons per hour, the temperature is 226ºC, the pressure is 2.4mpa, and it can be equipped with 9mw steam turbine and supporting power generation equipment.
5. Flue gas purification system
After the flue gas is discharged from the incinerator, dioxin will be significantly synthesized after passing through the cooling section. 200 ºC ~ 500 ºC is the most active temperature range for the reaction, and the maximum synthesis rate appears around 300 ºC. Shortening the residence time of the flue gas in this range can significantly reduce the generation of dioxins.
The average cooling rate of the flue gas is a key inhibitory factor. Generally, the flue gas cooling rate in the domestic waste incinerator is within the range of 100 ºC/s~200 ºC/s, and the dioxin concentration at the outlet of the corresponding furnace is generally 5 ng 1-TEQ/m3. To achieve the standard of less than 0.1 ng1-TEQ/m3, the flue gas cooling rate must be 500 ºC/s ~1000 ºC/s.
6. Flue gas washing process
The hot flue gas and the mixed powder material exchange heat and mass transfer and the following chemical reactions occur:
Ca(OH)2+2HCl=CaCl2+2H2O
Ca(OH)2+SO2=CaSO3+H2O
Ca(OH)2+SO3=CaSO4+H2O
The automatic control of the deacidification process mainly includes: SO2 emission concentration control-adjust the absorbent feed volume according to the SO2 content in the flue gas;
7. Bag dust collector
The compressed air required for dust removal by the bag filter is supplied by its own air compressor station. Because the bag filter has a good trapping effect on small particles, it has a high removal efficiency for the dry salt products and activated carbon powder produced during the desulfurization process. Especially after adopting the anti-acid Leighton filter, it is more suitable for occasions with strict control of acidic substances. The removal rate of SO2 in this flue gas purification system is greater than 90%, the removal rate of HCl is about 95%, and the purification rate of dust More than 99.99% can ensure that the flue gas emission meets the requirements of the national emission standard "Pollution Control Standard for Municipal Solid Waste Incineration".
