Abstract
The utility model discloses a reverse blowing spray drying system, which comprises a hot air furnace, a blower, a drying tower and a cyclone dust collector, wherein a hot air pipeline is connected between the blower and a reverse blowing device. Improvements are made on the prior art, the conventional way of reverse blowing drying with an electric heating device is eliminated, and the temperature of a dried material is lowered and wet air in the material is brought away by supplying hot air in a way of connecting the original hot air furnace in the system with the hot air pipeline, so that moisture condensation of the surface of the material is prevented. The reverse blowing spray drying system has the characteristics of small investment and reduction in energy consumption.
Description
Technical field
The utility model relates to a kind of spray drying technology field, especially a kind of spray drying system that adopts the blowback wind process.
Background technology
Spray-drying is a kind of method that the systematization technology is applied to dry materials, air is a hot-air by thermal conversion, through the hot-air distributor of pressure fan access to plant at the hothouse top, enter in the hothouse equably then, simultaneously feed liquid is delivered to the centrifugal atomizing machine (perhaps pressure nozzle) of device at the hothouse top via screw pump (perhaps high pressure homogenizer) and form minimum vaporific drop, feed liquid is contacted with hot-air and stream, moisture content evaporates rapidly, is finished product at extremely short time inner drying.Hot blast after water vapour and the heat exchange is discharged by air-introduced machine.At present the most frequently used method as shown in Figure 1, this method can directly make solution, emulsion be dried to powdery or graininess goods.Technological process is: liquid material enters in the drying tower 3 after filtering, make the material atomizing with pressure or centrifugation method, material droplet after the atomizing carries out heat exchange with the hot blast that enters in the drying tower 3, hot blast is to be provided by pressure fan 2 by hot-blast stove 1, take away the moisture content in the material, material is dried, and obtains the material of solid.The material of solid is brought to cyclone dust collectors 4 by air-introduced machine 10 and collects, and after the cooling that dehumidifies under the drive of introductory note blower fan 5, is collected by back-blowing device 7, and back-blowing device 7 is the whirly separator, obtains end product 8.
In the drying process with atomizing, the material of some easy moisture absorptions (as containing sugared Chinese medicine preparation, leather agent) adds the blowback drying after generally adopting the whirlwind rewinding, and the method with air of uniform temperature reduces dry back material temperature, takes away the humid air in the material.In order not make the material surface sweating, need blowback wind is heated to uniform temperature, what adopt in the technology of prior art is electrical heating method, is example with the drying tower of 3.5 meters of diameters, needs with the electric heater unit about 9KW.Therefore, the consumption with electric energy is bigger, problems such as cost of investment height.
The utility model content
The utility model is the shortcoming at above-mentioned existence, and a kind of technical scheme is provided, and makes full use of the hot-blast stove waste heat that drying device matches, and inserts dry hot blast, adds the blowback drying after supplying with the whirlwind rewinding, to reduce the consumption of the energy.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of spray drying system of blowback wind comprises hot-blast stove, pressure fan, drying tower, cyclone dust collectors, back-blowing device, it is characterized in that being connected with hot air duct between pressure fan and back-blowing device.Back-blowing device adopts the whirly separator usually, and the material of solid adopts air inducing to bring to cyclone dust collectors usually and collects, and after the cooling that dehumidifies under the drive of little air-introduced machine, is collected by back-blowing device, obtains end product.
In concrete the enforcement, it is characterized in that entering back-blowing device after above-mentioned hot air duct is through the dehumidifying heater.The dehumidifying heater is because in the winter time when temperature is very low, owing to adopt the hot-blast stove waste heat to heat, hot blast temperature is not enough, can enable lower powered dehumidifying heater and heat, and gets a desired effect.
The beneficial effects of the utility model are: the utility model passes through improvements over the prior art, the original electric heater unit that adopts of cancellation adds the blowback drying, connect hot air duct with hot-blast stove original in the system and guarantee hot-air, reduce dry back material temperature, take away the humid air in the material, make not dewfall of material surface to reach, have small investment, reduce the characteristics of energy resource consumption.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
The process flow diagram of Fig. 1 prior art.
The process flow diagram of Fig. 2 the utility model embodiment.
Among the figure: 1, hot-blast stove 2, pressure fan 3, drying tower 4, cyclone dust collectors 5, introductory note blower fan 6, dehumidifying heater 7, back-blowing device 8, finished product 9, hot air duct 10, air-introduced machine.
The specific embodiment
Among Fig. 2, a kind of spray drying system of blowback wind, comprise hot-blast stove 1, pressure fan 2, drying tower 3, cyclone dust collectors 4, introductory note blower fan 5, dehumidifying heater 6 and back-blowing device 7, pressure fan 2 is connected with hot air duct 9, be connected with back-blowing device 7 by dehumidifying heater 6, back-blowing device 7 is the whirly separator.
Among Fig. 2, its technological process is: liquid material enters in the drying tower 3 after filtering, make the material atomizing with pressure or centrifugation method, material droplet after the atomizing carries out heat exchange with the hot blast that enters in the drying tower 3, hot blast be by hot-blast stove 1 by pressure fan 2 and air-introduced machine 10 form system provide, take away the moisture content in the material, material is dried, obtain the material of solid, brought to cyclone dust collectors 4 by air-introduced machine 10 and collect, after the cooling that dehumidifies under the drive of introductory note blower fan 5, the material of solid is collected by back-blowing device 7, back-blowing device 7 is the whirly separator, gets finished product 8 to the end.In the drying process with atomizing, the material of some easy moisture absorptions (as containing sugared Chinese medicine preparation, leather agent) adds the blowback drying after generally adopting the whirlwind rewinding, and the method with air of uniform temperature reduces dry back material temperature, takes away the humid air in the material.In order not make the material surface sweating, need blowback wind is heated to uniform temperature, the utility model embodiment adopts the pressure fan 2 of hot-blast stove 1 to connect hot air duct 9 and guarantees hot-air, hot air duct 9 carries out the blowback cooling through dehumidifying heater 6 backs to material, reduce dry back material temperature, take away the humid air in the material, make not dewfall of material surface to reach, have small investment, reduce the characteristics of energy resource consumption.
