Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0021] Such as figure 1 The schematic diagram of the overall structure of the low-temperature coal dry distillation square furnace is shown, and the production process of low-temperature coal dry distillation is as follows:
[0022] 1. Low-temperature retort furnaces require the type of coal to be fed into the furnace to be bituminous coal, long-flame coal, non-caking coal or weakly caking coal, with a particle size of 20 to 120 mm;
[0023] 2. The raw coal is fed from the coal hopper 1 on the top of the furnace, enters into 4 auxiliary coal boxes 3 through 2 discharge rollers 2, and enters the top of the furnace through the auxiliary coal boxes 3. The gas collection umbrella 4 is installed on the top of the furnace. The umbrella 4 divides the materials again, and evenly distributes t...
