The invention relates to a two-section decomposing and melting method for glass batch. The method comprises the following steps: 1, heating glass batch to 300 DEG C-600 DEG C from room temperature for preheating and decomposing; 2, raising the temperature of the preheated glass batch in a melting furnace to 1580 DEG C to 1600 DEG C for completing decomposition, melting and settling processes. The first stage is carried out in an external decomposition flow bed (2), wherein the external decomposition flow bed (2) is provided with a material inlet (2a) and a material outlet (2b) and is sleeved with a revolving drum (9) with an auger so as to push and feed the glass batch into a insulation material bin (3), the glass batch is fed to a melting furnace feeding port (5) through a seal feeding machine (4); and the preheated heat sources can be various high-temperature smokes and natural gas in the glass melting furnace, other smokes with other high-calorific value and the like. The method has the advantages that (1) preheating volume and area in the furnace are saved and the melting capability of the melting furnace is improved; (2) comprehensive energy-saving effect is obvious, and dust emission is reduced; and (3) the erosion of glass batch steam (especially base steam) on the brick material of a melting furnace is reduced, and the service life of the melting furnace is improved.
Description
technical field [0001] The invention relates to a glass production method and device, in particular to a method and device for decomposing and melting glass batch materials. Background technique [0002] The practice of the traditional glass melting process is to put glass raw materials (batch materials) into the activated melting furnace at room temperature, and then undergo pyrolysis, melting, and clarification to form a glass state. On the one hand, since the batch material at room temperature is put into the melting furnace from the feeding port, there will be a section of batch material heating pre-melting section, which not only occupies the total volume and area of the melting furnace, consumes heat energy, and makes the melting capacity of the melting furnace not fully utilized. When the flame preheats the batch material in the furnace, the flame will easily blow off part of the powdery batch material, and the gas generated by the heated batch material will corrode...
