Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage incineration, in particular to a fly ash bin ash unloading and dust prevention structure. Background Art
[0002] Domestic waste incineration fly ash (hereinafter referred to as fly ash) is a powdery substance collected by the flue gas purification system of domestic waste incineration, with a particle size of less than 100μm. The amount of fly ash produced by waste incineration is calculated as 3% of the mass of the waste entering the furnace, and the flue gas purification fly ash produced by incineration throughout the year can reach 6.31026 million tons. Fly ash contains organic pollutants such as benzopyrene, benzanthracene, dioxin and heavy metals such as Cr, Cd, Hg, Pb, Cu, Ni, and is a highly dangerous solid waste. If fly ash is not properly disposed of, it will cause serious harm to the environment. The main component of fly ash is mineral phase, which can be used as a raw material for cement production. At the same time, harmful substances are degraded and solidified, that is, cement kiln coordinated disposal. However, due to the small particle size and light density of fly ash, secondary dust pollution is easily generated during storage and transportation.
[0003] The problem with the existing technology is that fly ash needs to be unloaded on a transport vehicle and transferred for subsequent treatment. During the unloading process of the fly ash bin, the fly ash is very likely to generate dust, causing leakage pollution of high-level solid waste.
[0004] Therefore, it is necessary to design a dust-proof structure during the fly ash bin unloading process to prevent fly ash leakage and to be able to recover the dust for treatment. Utility Model Content
[0005] In order to solve the deficiencies of the above-mentioned technology, the utility model provides a fly ash bin ash unloading and dust prevention structure.
[0006] The technical solution of the utility model is: a fly ash bin ash unloading and dust prevention structure, including a parking room, an ash unloading pipeline, an exhaust device, and a bag filter. The parking room is provided with an inlet and outlet, and the inlet and outlet are provided with movable door curtains. A floor scale device and a dust extraction pipe are arranged in the parking room, and the dust extraction pipe is connected with the exhaust device and the bag filter. The ash unloading pipeline enters the parking rack from the top.
[0007] By adopting the above technical scheme, a parking room is set up. After the vehicle transporting fly ash enters the parking room, the movable door curtain is closed to form a closed space in the parking room. The ash unloading pipeline is located directly above the vehicle, and the ash is unloaded to the transport vehicle in the closed space. The dust generated by the fly ash will not overflow. At the same time, the exhaust equipment is started, and the dust in the parking room is extracted by the dust extraction pipe and pumped to the bag filter for secondary filtration and is collected by the ash hopper again, thereby solving the dust pollution problem in the fly ash unloading process.
[0008] The scale equipment is installed to weigh the vehicles, observe the amount of ash unloaded, and compile factory data.
[0009] A further configuration of the utility model is as follows: a plurality of atomizing nozzles are arranged in the parking rack.
[0010] By adopting the above technical solution, after the ash unloading and dust removal are completed and before the vehicle is ready to leave the parking room, the atomizing nozzle is started to further suppress the dust, and then the movable door curtain is opened to drive out the vehicle.
[0011] A further configuration of the utility model is as follows: the floor scale equipment comprises a PLC controller, and the PLC controller controls the start and stop of the fly ash bin unloading according to the floor scale equipment data.
[0012] By adopting the above technical solution, through the control linkage between the floor scale equipment and the fly ash bin unloading valve and other equipment, the ash unloading valve is automatically closed before the transport vehicle is fully loaded, so as to avoid the unloading of too much fly ash, which may cause fly ash overflow and increase of dust.
[0013] The utility model is further configured as follows: the movable door curtain is an electrically controlled door curtain, and the PLC controller controls the opening and closing of the electrically controlled door curtain according to the data of the floor scale equipment.
[0014] By adopting the above technical solution, the control of the weighing equipment and the electric-controlled door curtain is linked. After the driver completes the ash unloading, he does not need to get off the vehicle to open the door curtain, which reduces the operation and protects the driver from contact with fly ash.
[0015] The beneficial effects of the utility model are as follows: the dust is filtered twice by the parking room, dust extraction pipe, bag filter and other equipment, and then collected by the ash hopper again, thereby solving the dust pollution problem in the fly ash unloading process. At the same time, the atomizing nozzle is further suppressed, and the floor scale, electric control door curtain and other settings are set to optimize the entire unloading process.

[0021] The following is a detailed description of the utility model inlet line in conjunction with the accompanying drawings. Figure 1-2 As shown, a fly ash bin ash unloading and dust prevention structure includes a parking room 1, an ash unloading pipeline 2, an exhaust device, and a bag filter 3. The parking room 1 is provided with an inlet and outlet 11, and the inlet and outlet 11 is provided with a movable door curtain 12. A floor scale device 4 and a dust extraction pipe 13 are arranged in the parking room 1, and the dust extraction pipe 13 is connected with the exhaust device and the bag filter 3. The ash unloading pipeline 2 enters the parking rack from the top.
[0022] By setting up the parking room 1, after the vehicle transporting fly ash enters the parking room 1, the movable door curtain 12 is closed to form the parking room 1 into a closed space. The ash unloading pipeline 2 is located directly above the vehicle, and the ash is unloaded to the transport vehicle in the closed space. The dust generated by the fly ash will not overflow. At the same time, the exhaust equipment is started, and the dust in the parking room 1 is extracted by the dust extraction pipe 13 and pumped to the bag filter 3 for secondary filtration and is collected by the ash hopper again, thereby solving the dust pollution problem in the fly ash unloading process.
