Description
Technical field
The present invention relates to a kind of spray drying corollary equipment, especially relate to a kind of test-type noble gas blood circulation.
Background technology
Spray dryer is the one of continuous way atmospheric dryer.With special installation by liquid material atomisation so that it is be dried with hot air.For being dried the liquid of some thermal sensitivity, suspension and viscous liquid, such as milk, egg, tannin and medicine etc..It is also used for drying fuel, intermediate, soap powder and inorganic salt etc..
Air, through filtering and heating, enters exsiccator headspace allotter, and hot-air is in the shape of a spiral evenly into hothouse.Feed liquid is through the high speed centrifugal atomization device at tower body top, and (rotation) sprays into imperceptible vaporific liquid pearl, with hot-air flow to contact and can be dried as finished product within the extremely short time.Finished product is exported by bottom drying tower and in cyclone separator continuously, and waste gas is emptied by air-introduced machine.
Existing experiment type spray drier mostly is open, and tail gas directly discharges, it is impossible to carry out being dried containing solvent material spray flammable, toxic, it is impossible to be dried the material being oxidized easily.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of test-type noble gas blood circulation is provided, laboratory spray is coordinated to be dried use composition enclosed noble gas blood circulation, it is dried and solvent recovery containing solvent material spray flammable, toxic, and the material being oxidized easily can be dried.
The purpose of the present invention can be achieved through the following technical solutions；
A kind of test-type noble gas blood circulation, enclosed noble gas blood circulation is formed with spray dryer, described test-type noble gas blood circulation includes filter, preheater, condenser, dehumidifier, refrigeration unit and solvent receiving flask, pass sequentially through pipeline between the entrance of described filter, preheater, condenser and dehumidifier to connect, the outlet of described dehumidifier is connected with preheater again by pipeline, described refrigeration unit is connected with condenser, and described solvent receiving flask is located on the pipeline between condenser and dehumidifier.
Pipeline between described condenser and solvent receiving flask is provided with temperature controller.
The described pipeline before solvent receiving flask is provided with valve.
Pipeline between described dehumidifier and condenser is provided with pressure transducer and automatic decompression device, and described pressure transducer is connected with automatic decompression device.
Pipeline between described dehumidifier and preheater is provided with oxygen sensor and automatic noble gas gatherer, and described oxygen sensor is connected with automatic noble gas gatherer.
The condensation temperature of condenser is controlled by temperature controller；The built-in flammable gas alarm of body of spray dryer, is monitored flammable escaping gas, improves device security energy；Oxygen content in system is measured and controls in real time by described oxygen sensor, and oxygen concentration exceedes setting value, and system is automatically imported noble gas；System pressure is measured and controls in real time by pressure transducer, hypertonia system releasing pressure automatically, makes system pressure be maintained at set point.
The noble gas being loaded with solvent and steam drawn from spray dryer outlet sequentially enters preheater and condenser after filter filters out solid particle, solvent therein and steam flow in solvent receiving flask after being condensed, noble gas is after dehumidifier dehumidifies, and flow out after again passing by preheater preheating, it is spray dried device and recycles.
Compared with prior art, the test-type noble gas blood circulation of the present invention can realize coordinating laboratory spray dryer composition enclosed noble gas blood circulation, it is dried and recycled solvent containing solvent material spray flammable, toxic, and the material being oxidized easily can be dried；Present configuration is compact, and volume is little, easy for installation, and security performance is high.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of test-type noble gas blood circulation, as shown in Figure 1, enclosed noble gas blood circulation is formed with spray dryer, test-type noble gas blood circulation includes filter 1, preheater 2, condenser 3, dehumidifier 6, refrigeration unit 4 and solvent receiving flask 5, pass sequentially through pipeline between the entrance of filter 1, preheater 2, condenser 3 and dehumidifier 6 to connect, the outlet of dehumidifier 6 is connected with preheater 2 again by pipeline, refrigeration unit 4 is connected with condenser 3, and solvent receiving flask 5 is located on the pipeline between condenser 3 and dehumidifier 6.Pipeline between condenser 3 and solvent receiving flask 5 is provided with temperature controller 8.Pipeline before solvent receiving flask 5 is provided with valve 12.Pipeline between dehumidifier 6 and condenser 3 is provided with pressure transducer 7 and automatic decompression device 9, and pressure transducer 7 is connected with automatic decompression device 9.Pipeline between dehumidifier 6 and preheater 2 is provided with oxygen sensor 10 and automatic noble gas gatherer 11, and oxygen sensor 10 is connected with automatic noble gas gatherer 11.
The condensation temperature of condenser 3 is controlled by temperature controller 8；The built-in flammable gas alarm of body of spray dryer, is monitored flammable escaping gas, improves device security energy；Oxygen content in system is measured and controls in real time by oxygen sensor 10, and oxygen concentration exceedes setting value, and system is automatically imported noble gas C by automatic noble gas gatherer 11；System pressure is measured and controls in real time by pressure transducer 7, and during hypertonia, system passes through automatic decompression device 9 releasing pressure automatically, makes system pressure be maintained at set point.
The noble gas A being loaded with solvent and steam drawn from spray dryer outlet sequentially enters preheater 2 and condenser 3 after filter 1 filters out solid particle, solvent therein and steam flow in solvent receiving flask 5 after being condensed, condensed noble gas is after dehumidifier 6 dehumidifies, and become the noble gas B through recycling design after again passing by preheater 2 preheating, flow out from preheater 2 through the noble gas B of recycling design, be spray dried device and recycle.Preheater 2 both can reduce refrigeration machine load with cooling hot gas, it is possible to preheats condensed noble gas and again recycles.
