Embodiment Construction

[0029] see figure 1 , a multi-layer belt drying system, including a drying box 5 with two air outlets 2 on the top and five layers of conveyor belts 12 made of perforated stainless steel sheets located in the drying box 5, the bottom conveyor belt The input end of the upper layer is connected to the output end of the adjacent conveying mesh belt. There are several circulating fans 13 under each layer of conveying mesh belt. The distribution density of the circulating fans 13 is every 2.5-4m 2 The area of ​​the conveyor belt is set to one.

[0030] The multi-layer belt drying system also includes:

[0031] The air supply pipe 17 communicates with the air supply port 15 at the bottom of the cooling chamber for transporting air;

[0032] The exhaust pipe 3 communicates with the two exhaust outlets 2 on the top of the drying box, and each exhaust outlet is provided with a dehumidification fan 4, and the outlets of the two dehumidification fans are aggregated to the exhaust pipe ...

Abstract

The invention discloses a multi-layer belt type drying system. The multi-layer belt type drying system comprises a drying box with an exhaust port in the top and multiple layers of transmission net belts in the drying box, wherein the input end of the lower-layer transmission net belt is connected with the output end of the adjacent upper-layer transmission net belt, and a plurality of circulation fans are arranged under each layer of transmission net belt. A horizontal separation plate dividing the drying box into a drying chamber and a cooling chamber is arranged in the drying box, an air feeding port is formed in the bottom of the cooling chamber, a draught fan used for exhausting the air is arranged inside the cooling chamber, the air feeding port and the draught fan are arranged at two sides of the transmission net belts, a heater is arranged in the drying chamber, an air inlet of the heater is communicated with an air outlet of the draught fan, and a plurality of air outlets corresponding to the transmission net belts in the drying chamber one to one are formed in the heater. The multi-layer belt type drying system is simple in structure and reasonable in arrangement, preheats a heating medium by recycling waste heat of off gas and utilizing dried upgrading materials with high temperature, and lowers the energy consumption in the drying process.

Description

technical field [0001] The invention relates to a belt drying system, in particular to a multi-layer belt drying system. Background technique [0002] The lignite resource reserves that have been discovered in my country are huge and the price is low. However, lignite is the coal with the lowest degree of coalification. It has large porosity, high volatile matter, oxygen content of 15% to 30%, and high moisture content. The total moisture content can generally reach 20%. ~50%, easily weathered in the air, belongs to low-to-medium calorific value coal, which is not conducive to long-distance transportation and long-term storage. Due to high moisture content, direct combustion for power generation without drying, low flame temperature, difficult burnout, and low thermal efficiency. At present, with the development of industrial and agricultural production and the rapid increase of urban population, a large amount of domestic sewage and industrial wastewater have been brought in...
