Problems solved by technology
This technology has the following defects: because the compressed air is mixed with the dust removal additive in the oil storage tank, and the space of the oil storage tank is small, it cannot be fully mixed; because the oil storage tank is equipped with a heating device, the oil is mixed with the air in the oil storage tank, Once the heating device is out of control, it is easy to cause an explosion, and the consequences are disastrous

Embodiment Construction
[0013] The present invention is specifically described below in conjunction with accompanying drawing, as figure 1 As shown, a certain amount of dedusting agent is stored in the oil storage tank 1, which is equipped with an electric heater 2 inside. The dedusting agent (in this embodiment, engine oil) is sprayed out through the pump 3 after being heated, and then passed through the oil injection nozzle 7 and the compressed air 6 After working together, they are atomized and sprayed to the screw conveyor 8. The flow and pressure of the dedusting agent are adjusted through the flow regulating valve 5. The dedusted calcined coke is sent to the calcined coke storage bin 11 through the bucket elevator 9 and the belt 10.
[0014] The oil storage tank 1 is provided with a high and low liquid level gauge and a temperature sensor, which can display the liquid level and temperature of the dedusting agent online.
[0015] The pump 3 is used to provide circulation power for the dedusting ...

The invention discloses a dust removal method and device for coke loading and unloading. Engine oil is sprayed during coal loading and unloading, and a spraying method of the engine oil comprises thestep of mixing the engine oil and high-pressure air through a high-pressure spray head, and the engine oil spraying amount accounts for 0.1% to 0.3% of the weight of coal. The dust removal method hasthe beneficial effects that according to the system, a dust removal agent is sprayed to coal dust in calcined coke, carbon dust transportation loss is avoided, and the production cost is reduced; andmeanwhile, the operation environment in the production and transportation process is improved. According to the system, a dust removal agent is independently heated in an oil storage tank, no air is mixed, and therefore explosion danger is avoided; and in addition, due to the fact that compressed air and engine oil are mixed on a nozzle, the mixing effect can be improved.
Description
technical field [0001] The invention relates to a dust suppression system, in particular to a dust removal method and device during coal loading and unloading. Background technique [0002] In recent years, with the rapid development of the market price of raw materials and the electrolytic aluminum industry, tank calciners have more prominent advantages in the field of calcining petroleum coke and gradually occupy the market. Corresponding professional large-scale calcining enterprises have also emerged, such as calcined coke plants with an annual output of 500kt / a. Some foreign owners or calcined coke suppliers are looking for partners in China to establish professional calcining enterprises and ship some calcined coke products abroad. However, during the loading and unloading and shipping process of calcined coke wharf, there is a large amount of carbon dust flying, which not only causes product loss, but also pollutes the environment. According to statistics, the annua...
