Problems solved by technology
[0002] At present, most of the traditional coking ovens are intermittent coking. The coal burned in the furnace is generally room temperature wet coal for coking directly without dehydration. In this way, a large amount of waste water will be generated during the entire coking process, causing environmental pollution and high energy consumption. Not conducive to energy saving and emission reduction

The invention relates to a dehydrating device of coal as fired for a coal pyrolysis furnace. A coal hopper (7) is connected with a first hopper handle (5), a hopper handle blanking slot (3) is arranged above the first hopper handle (5), the hopper handle blanking slot (3) is connected with a first dehydrating device (4), a coal bin (6) is arranged below the first dehydrating device (4), a bag type dust collector (2) is arranged above the coal bin (6), the bag type dust collector (2) is connected with an exhaust funnel (1), a coal bin hopper (9) is arranged below the coal bin (6), the coal bin hopper (9) is connected with a spiral conveyer (8), one side of the spiral conveyer (8) is connected with a second hopper handle (5); a second dehydrating device (4) and a third dehydrating device (4) are arranged at the right side of the coal hopper (7), and a cyclone dust collector (10) is arranged between the second dehydrating device (4) and the third dehydrating device (4). The dehydrating device of coal as fired for the coal pyrolysis furnace produces no waste water in the whole technological process and has the advantages of low energy consumption and no pollution.
Description
technical field [0001] The invention belongs to a coking oven, in particular to a coal pyrolysis furnace coal dehydration device. Background technique [0002] At present, most of the traditional coking ovens are intermittent coking. The coal burned in the furnace is generally room temperature wet coal for coking directly without dehydration. In this way, a large amount of waste water will be generated during the entire coking process, causing environmental pollution and high energy consumption. Not conducive to energy saving and emission reduction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dehydration device for the incoming coal of the coal pyrolysis furnace. The incoming coal is dried and dehydrated, quickly preheated and tempered, and then coking is carried out instead of normal temperature wet coal directly into the furnace for coking, and the energy consumption is small. , no pollution. [0004] T...
