Abstract

The invention relates to a high-temperature-resistant double-layer feeding system which comprises a discharging chute (3) provided with a feeding inlet (1), a discharging outlet (2) and a double-layer bottom plate. The high-temperature-resistant double-layer feeding system is characterized in that a flame retardant device is further arranged on the discharging chute (3) and used for preventing deflagration of materials which are guided into a dryer. Accordingly, the high-temperature-resistant double-layer feeding system has the following advantages of (1) being reasonable in design, simple in structure and completely practical and (2) being capable of completely eliminating safety accidents like easy combustion and explosion of brown coal.

Description

technical field [0001] The invention relates to a feeding system, in particular to a high-temperature-resistant double-layer feeding system. Background technique [0002] Lignite is the youngest coal to form among the earth's fossil solid fuels. It is characterized by a very high volatile content, which determines that the explosiveness and flammability of this kind of coal are very strong during baking, and the moisture content in the coal is also very high, generally as high as about 40%. In particular, the internal moisture of coal is not easy to remove, which also determines that the calorific value of lignite is very low, and the content of fixed carbon is also very low. The ash content is moderate, the tar content is high, and the sulfur content can be high or low according to the lignite origin, which will lead to the lignite desulfurization system must be considered in accordance with the national environmental protection policy during the lignite baking process. ...
