Briquette static cage-drawer-type undamaged drying device and using method

Abstract

The invention discloses a briquette static cage-drawer-type undamaged drying device and a using method. The briquette static cage-drawer-type undamaged drying device comprises a hot blast furnace for providing hot blast. The hot blast furnace is connected to an air distribution pond by a hot air tube. The hot air tube is provided with an induced draft fan. The air distribution pond is provided with an iron cage drawer for storing the briquette, and the bottom is the uniformly distributed ventilation-type structures. The side walls and the bottom of the air distribution pond are provided with insulating layers. The opening of the air distribution pond is covered by the cage drawer. One end, adjacent to the hot air tube, of the air distribution pond is provided with a wind-proof pressure-regulating wall. The air distribution pond is internally provided with a temperature sensor. The briquette static cage-drawer-type undamaged drying device uses the moveless and collisionless static drying mode, the breakage rate is 1%, an adhesive is saved by 40%-50%, the working efficiency is high, the practicability is high, the manual operation cost and the fuel cost are saved, the manufacturing cost of the briquette per ton is reduced by 40-60 Yuan, the structure is simple, the manufacturing cost of the device is low, and the reliability of the device is high.

Description

technical field [0001] The invention relates to the field of drying, in particular to a static cage-type non-damage drying device for briquettes and a method for using it. Background technique [0002] Briquette has the advantages of smokeless combustion, clean emission and sufficient combustion, and has been widely used in industry and civil use. During the production process of briquettes, a small amount of water needs to be added. The moisture in the briquettes directly affects the strength and quality of the briquettes. The less moisture in the briquettes, the better. Therefore, it is necessary to dry the processed briquettes. The processing and drying steps are very important for the quality of coal briquettes. If the humidity is too high, the strength quality will be affected, and more harmful gases will be generated during combustion. The existing drying kilns use heat transfer through grilles or iron nets. If the heat delivery hole is too large, the humidity will be...

AI Technical Summary

Problems solved by technology

The shortcoming of this kind of drying furnace is: during the falling process of the molded coal, due to mutual extrusion and friction between the molded coals, more powder is produced, and at the same time, the damage rate of the molded coals is relatively high.

In order to reduce the breakage rate of coal briquettes, those skilled in the art add materials such as coagulant to coal briquettes. However, the briquettes made by this method have relatively large deficiencies. While increasing the weight of briquettes, the briquettes are reduced The flammability of coal will cause greater economic losses to users

Another disadvantage of the vertical drying furnace is: due to the large area in the furnace, the ventilation is uneven, the drying uniformity of the briquettes is low, and manual drying is often required, resulting in low production efficiency.

However, the free-fall transfer mode adopted by the transport carrier is very unsuitable for briquettes with high moisture content and loose structure, which will cause a large amount of crushing, the crushing rate is as high as 10%, and the production cost is high
