Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spray drying tower, in particular to a spray drying tower with recyclable waste heat. BACKGROUND

[0002] The spray drying tower is a device in which air passes through a filter and a heater, enters an air distributor at the top of the drying tower, and then spirally and uniformly enters a drying chamber. The feed liquid is pumped by a pump through a filter to a centrifugal atomizer at the top of the drying tower, so that the feed liquid is sprayed into extremely small mist droplets. The feed liquid is in contact with the hot air in parallel flow, and the water is rapidly evaporated to be dried into a finished product in a very short time. The finished product is discharged from the bottom of the drying tower and a cyclone separator. The exhaust gas is discharged by a fan. The spray drying tower can spray material in solution state into the spray drying tower, and the material is discharged in solid powder state after drying. It is widely used in the drying of biological pesticides, medicines and food microorganisms. It is a device that can complete drying and granulation at the same time. The pressure, flow rate and size of the spray hole of the liquid pump can be adjusted according to the process requirements to obtain spherical particles of a certain size ratio. The spray drying machine is a continuous normal pressure dryer. Liquid material is sprayed into mist by special equipment, which is in contact with hot air to be dried. It is used for drying some heat-sensitive liquids, suspensions and viscous liquids, and also for drying fuels, intermediates, soap powder and inorganic salts. Spray drying realizes rapid evaporation of water by using hot air as carrier, but due to the decrease of temperature and relative humidity in the tail gas after water evaporation, there is still a lot of heat in the tail gas. Direct discharge is a waste of resources. It is divided into: pressure spray drying method; centrifugal spray drying method; air flow type spray drying method. At present, the exhaust gas preheating generally adopts conventional tube heat exchanger to exchange heat with the drying tower inlet air to preheat the drying tower inlet air. However, the waste heat inside the equipment cannot be utilized. When the waste heat is utilized, the impurities mixed in the gas are easy to accumulate during treatment, which reduces the effect of waste heat treatment of the equipment after a long time without cleaning, and small particles are easy to be discharged to the outside in the untreated gas discharge.
