Description

A kind of drying system

Technical field

The utility model relates to the chemical drying technical field, especially a kind of drying system.

Background technology

Drier is by heating, hygroscopic water (referring generally to moisture or other volatile liquid components) vaporization in material to be overflowed, and stipulates the plant equipment of the solid material of moisture content with acquisition.

Present stage, a most widely used class drier comprises fluidized drier, pneumatic conveyer dryer, tray dryer, spray dryer, tunnel dryer etc.The main feature of this type of drier is: 1. thermal current directly contacts with solid, and heat is passed to wet solid in the convection heat transfer' heat-transfer by convection mode by thermal current, and the steam that produces is taken away by air-flow; 2. hot stream temperature can be brought up to the tolerant maximum temperature of ordinary metallic material (approximately 730 ℃), and at high temperature radiant heat transfer will become main heat transfer type, and can reach very high heat utilization ratio; 3. the humidity of air-flow is influential to the final water content of rate of drying and product; When 4. using low-temperature airflow, need that usually air-flow is first done dehumidification and process; The energy consumption of the unit mass of 5. vaporizing moisture is high than the conduction-type drier, when the final products water content is low more so; 6. need a large amount of thermal currents to guarantee the required heat of moisture vaporization, if the particle diameter of the material that is dried is very little, dust arrester is huge and cost is more; 7. should operate near under condition of normal pressure.

The rate of drying of material depends on the diffusion rate of surperficial boil-off rate and inner hygroscopic water.Usually the rate of drying of the early stage of drying is controlled by surperficial boil-off rate; Then, as long as dry external condition is constant, it is stable that the rate of drying of material and surface temperature namely keep, and this stage is called constant rate drying period; When the material moisture content is reduced to a certain degree, inner hygroscopic water reduces to the diffusion rate on surface, and during less than surperficial boil-off rate, rate of drying is namely mainly determined by diffusion inside speed, and constantly reduce with the reduction of moisture content, this stage is called falling rate drying period.

Because drier need to consume a large amount of heat energy in dry run, in order to save energy, the material that some moisture content is high, the suspension that contains solid matter or solution are general first through mechanical dehydration or heating evaporation, then at the drier inner drying, with the solid that obtains doing.

In field of medicine and chemical technology, the most frequently used drying system is that centrifuge is connected with chamber dryer, utilizes chamber dryer to carry out drying to the material after centrifugal, yet because material is placed in drying on handcart, material can't stir, therefore, need the dry time longer, and energy consumption is higher.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of drying system.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of drying system, formed by mother liquor tank, centrifuge, double-cone dryer and vavuum pump, described centrifuge is provided with discharge gate and leakage fluid dram, the liquid storage mouth pipeline connection of the leakage fluid dram of described centrifuge and described mother liquor tank, the discharge gate of described centrifuge is connected with the feeding mouth of described double-cone dryer, the dehumidifier mouth of described double-cone dryer and the bleeding point pipeline connection of described vavuum pump.

Preferably, above-mentioned drying system also comprises surge tank, the dehumidifier mouth pipeline connection of the inlet of described surge tank and described double-cone dryer, the bleeding point pipeline connection of the liquid outlet of described surge tank and described vavuum pump.

Preferably, above-mentioned drying system, described surge tank are the gasbag-type surge tank.

Preferably, above-mentioned drying system, the discharging opening of described double-cone dryer is connected with packaging production line.

Preferably, above-mentioned drying system, described double-cone dryer are bipyramid rotary dryer.

The utility model structure has following beneficial effect:

Above-mentioned drying system, simple in structure, easy and simple to handle, material in double-cone dryer carries out drying by the mode that vacuumizes and rotate, make dry materials speed obviously accelerate, energy consumption significantly reduces, and in dry run, material is blendable more even, has improved operating efficiency, is fit to the needs of large-scale industrial production.
