Abstract
The utility model relates to a closed circulating flow drying device, which is widely suitable for drying materials in a chemical industry, a medicine industry, a food industry, etc., and comprises a drier (1), a dust remover (2), a blower (7), a heating filter (8) and a connecting pipeline. A hot gas inlet of the drier (1) is connected with a hot gas outlet of the heating filter (8), and the gas inlet of the heating filter (8) is connected with the outlet of the blower (7). The hot gas outlet of the drier (1) is connected with the inlet of the dust remover (2). The utility model is characterized in that the outlet of the dust remover (2) is connected with the hot gas inlet of a condenser (3), and the cold gas and the hot gas outlets of the condenser (3) are connected with the inlet of the blower (7). A solvent outlet of the condenser (3) is connected with a solvent storing tank (4). The utility model is safe, can reclaim solvent and is favorable to environment protection.
Description
Technical field:
The utility model relates to a kind of drying device, especially relates to a kind of closed cycle fluidized drying device.Be widely used in industry dry materials such as chemical industry, medicine, food, be particularly useful for the dry materials of anaerobism, poisonous and harmful, needs recovery menstruum.
Background technology:
Before the utility model was made, public known fluidisation attitude drying device was open circuit operation, and hot gases is directly externally discharging after use.Its structure is made up of hot filtration apparatus, fluid bed, deduster and blower fan.Its operation principle is: material is added in the fluid bed by the charge door of fluid bed one end, places on the interior orifice plate, and hot gas from bottom to top passes orifice plate and material bed with the material heat drying, and dried material is discharged the bed body through fluid bed other end discharge gate.Because hot gas uses directly externally discharging of back, therefore has following shortcoming:
1, the solvent boil-off gas that contains in the hot gas can not reclaim;
2, contain the directly externally discharging of hot gas of solvent gas, contaminated environment, unfavorable environmental protection;
3, anaerobism or be difficult for protection when containing the dry materials of inflammable and explosive solvent.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of safe and reliable, can reclaim solvent, be beneficial to the closed cycle fluidized drying device of environmental protection.
The purpose of this utility model is achieved in that a kind of closed cycle fluidized drying device, comprise drier, deduster, blower fan, hot filtration apparatus and connecting line, the hot gas import of described drier is connected with the outlet of the hot gas of hot filtration apparatus, and the gas feed of hot filtration apparatus links to each other with the blower fan outlet; The hot gas outlet of drier links to each other with the deduster import, it is characterized in that: described deduster outlet links to each other with the hot gas import of condenser, and the cold air outlet of condenser links to each other with the blower fan import, and the solvent outlet of condenser links to each other with the solvent basin.Wet stock is by the quantitative or disposable adding fluid bed of fluid bed one end, and hot gas enters fluid bed and from bottom to top passes material bedly, forces material to move simultaneously the material heat drying to the port of export, and dry material holds discharge gate to discharge outside the bed through other.Hot gas temperature reduces, and humidity increases, and by the deduster dedusting, dry, go into fluid bed and recycle through the hot filtration apparatus heat temperature raising is laggard through condenser again, forms fluid bed closed cycle fluidized drying device like this.Solvent gas in the hot gas enters the solvent basin and reclaims after the condensation in condenser.
The utility model closed cycle fluidized drying device, described blower fan import links to each other with the nitrogen basin by automatic valve.When adopting nitrogen protection in the system, the nitrogen in the nitrogen basin by automatic valve to the automatic supply of system.
Compare with existing open type fluidized drying device, the utlity model has following advantage:
1, the solvent boil-off gas that contains in the hot gas can reclaim;
2, contain the not externally discharging of hot gas of solvent gas, the protection environment is beneficial to environmental protection;
3, anaerobism or be easy to protection when containing the dry materials of inflammable and explosive solvent.
Description of drawings:
Fig. 1 is the utility model fixed fluidized bed closed cycle fluidized drying equipments overall structure schematic diagram.
Fig. 2 is the vibration fluidized bed closed cycle fluidized drying of a utility model equipments overall structure schematic diagram.
The specific embodiment:
Referring to Fig. 1, Fig. 1 is a fixed fluidized bed closed cycle fluidized drying device, is made up of fixed fluidized bed 1, deduster 2, condenser 3, solvent basin 4, nitrogen basin 5, automatic valve 6, blower fan 7, hot filtration apparatus 8 and connecting line.Described fixed fluidized bed 1 hot gas import is connected with the hot gas outlet of hot filtration apparatus 8, and the gas feed of hot filtration apparatus 8 links to each other with blower fan 7 outlets; The hot gas outlet of fixed fluidized bed 1 links to each other with deduster 2 imports, deduster 2 outlets link to each other with the hot gas import of condenser 3, the cold air outlet of condenser 3 links to each other with blower fan 7 imports, the solvent outlet of condenser 3 links to each other with solvent basin 4, and nitrogen basin 5 links to each other with blower fan 7 imports by automatic valve 6.
Referring to Fig. 2, Fig. 2 is the utility model vibrated fluidized bed closed cycle fluidized drying device, and 1 is vibrated fluidized bed, and vibrating motor 9 orders about a body vibration, and the fluidisation that is beneficial to material in the body is with mobile.All the other devices and embodiment are with fixed fluidized bed closed cycle fluidized drying device.
Claims (4)
1, a kind of closed cycle fluidized drying device, comprise drier (1), deduster (2), blower fan (7), hot filtration apparatus (8) and connecting line, the hot gas import of described drier (1) is connected with the hot gas outlet of hot filtration apparatus (8), and the gas feed of hot filtration apparatus (8) links to each other with blower fan (7) outlet; The hot gas outlet of drier (1) links to each other with deduster (2) import, it is characterized in that: described deduster (2) outlet links to each other with the hot gas import of condenser (3), the cold air outlet of condenser (3) links to each other with blower fan (7) import, and the solvent outlet of condenser (3) links to each other with solvent basin (4).
