Embodiment

[0030] Dry the cemented carbide mixture with alcohol as the solvent. As shown in the figure, the slurry is firstly sent to the degassing tank by the vacuum pump to increase the power to separate the air in the slurry, and then sent to the filter to filter the slurry. The slurry is pressurized by a vacuum pump and sent to the atomizer located in the spray drying tower for atomization. Because the spray drying tower is filled with high-temperature nitrogen, the spray drying tower is filled with high temperature nitrogen, so the mist slurry and the working steam conduct contact heat exchange, so that The slurry dries instantaneously to form a granular product while generating mixed steam. The product enters the cyclone separator with the working gas, and the cemented carbide mixture particles are discharged from the bottom of the cyclone separator. The mixed steam enters the circulation pipe 1 and the circulation pipe 2 through the induced draft fan. The mixed steam entering the c...

Abstract

The invention discloses an energy-efficient closed-cycle spray drying system. The energy-efficient closed-cycle spray drying system comprises a vacuum pump, a degassing tank, a filter, an atomizer, a gas content detector, a spray drying tower, a cyclone separator, an induced draught fan, a refrigerant circulation loop, a heat exchanger, a nitrogen supplementary device, an electric heater, and the like. The energy-efficient closed-cycle spray drying system can be used for recycling and reusing of heat energy of steam discharged from drying towers, and recycling and reusing of organic solutions in the steam at the same time. In the energy-efficient closed-cycle spray drying system, high temperature nitrogen is taken as drying gas, so that product quality is improved effectively, and oxidation of products in production process is avoided.

Description

Technical field [0001] The invention relates to an energy-saving and highly efficient closed-circuit spray drying system, which is particularly suitable for organic solution slurry and belongs to the technical field of drying. Background technique [0002] The spray drying technique was invented by La Mont and Percy at the end of the 19th century. Due to the development of the food industry, this technology was first applied to the manufacture of skimmed milk powder, and later in the dairy industry, solid beverages, solid condiments and other food industries. At the same time, it is often used in the detergent industry, pharmaceutical industry, ceramics, and environmental protection industries. Today, your technology has been continuously improved and innovated. This technology is also applied to the development of equipment with different liquid characteristics (such as concentration, viscosity, surface tension, etc.) and the development of drying aids. [0003] The spray dryer d...
