Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal distribution, in particular to a multi-channel bin distribution system. Background Art
[0002] In the prior art, a bin, especially a multi-channel bin coal hopper for supplying coal to a coal-fired device, usually has a coal dropping port for each multi-channel bin coal hopper to supply coal to a specific coal-fired device. For example, small and medium-sized thermal power plants are equipped with at least 5 to 6 boilers, and large-scale thermal power plants are equipped with more than a dozen boilers. Each boiler is usually equipped with a coal bin storing a specific coal quality with high or low calorific value. That is, the coal stored in each multi-channel bin coal hopper has different qualities, and the corresponding boiler can only use coal of a single quality. When burning low-calorific value coal during peak power consumption periods, it is impossible to obtain high heat energy for power generation, and the unit has problems such as inability to change coal types in time and accurately distribute coal. The conventional solution to solve the above problems is to install a partition in the raw coal bin. In actual operation, it is very difficult to keep the coal levels on both sides of the partition the same, which will lead to load imbalance. The partition used for long-term operation has the risk of deformation, cracking, and collapse. Seriously, it will cause some welds of the coal bin to tear, and there is a risk of the overall coal bin falling off, which will form a greater safety hazard! There is a problem of coal blockage in the bin transformation with a partition installed in the middle. After the bin is transformed with a partition, due to the unreasonable structure of the multi-channel bin coal hopper, when low-quality coal is put into operation, it will cause frequent coal blockage in the multi-channel bin coal hopper, resulting in the failure of the transformation.
