Abstract
The invention provides a double pulse air flow drying machine, comprising a cyclone cluster, an air filer, a vapor heater, a material feeder, a plurality of pulse drying tubes, a first-stage cyclone separator, a second-stage cyclone separator, a pulse bag-type dust collector and a draft fan, wherein the cyclone cluster is connected with the air filter; the air filter is connected with the vapor heater; the vapor heater is connected with the material feeder; the material feeder is connected with the plurality of pulse drying tubes; the plurality of pulse drying tubes are connected by heating tubes, a pulse drying tube at a relatively back part is connected with the first-stage cyclone separator; the first-stage cyclone separator is connected with the second-stage cyclone separator; the second-stage cyclone separator is connected with the pulse bag-type dust collector; the pulse bag-type dust collector is connected with the draft fan; and an air adjusting valve is arranged at the draft fan. The double pulse air flow drying machine provided by the invention has the beneficial effects that a pulse air flow tube is used as a reinforced heat exchange structure for dehumidifies materials rapidly by changing the relative velocity of materials and thermal media and reinforcing heat transfer and mass transfer process.
Description
Technical field
The present invention relates to a kind of dipulse pneumatic drier, belong to the drier unit field.
Background technology
Pneumatic drier be a kind of continuously, efficiently, fluidization of solid drying equipment fast.Loose powder and granule shape material dispersion suspension is in hot-air, and moment removes moisture content in the process that air-flow is carried secretly, is applicable to the drying of the powder and granule shape material surface water of particle size range between 5 μ m-5mm.
Existing pneumatic drier is the pulsed pneumatic drying machine particularly, often adopts the form of pulse, for the higher material of initial moisture content, adopts single-stage pulsed pneumatic drying machine can't reach the whole moisture content requirement of product.
Summary of the invention
The technical problem that the present invention will solve is to overcome existing single-stage pulsed pneumatic drying machine can not reach the dry problem that requires for the higher material of initial moisture, and a kind of dipulse pneumatic drier is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The dipulse pneumatic drier; Comprise cyclone cluster, air cleaner, steam heater, feeder, several impulse drying pipes, primary cyclone, secondary cyclone, pulsed jet cloth filter, air-introduced machine, wherein cyclone cluster is connected with air cleaner, and air cleaner is connected with steam heater; Steam heater is connected with feeder; Feeder is connected with several impulse drying pipes, between several impulse drying pipes, connects through heating tube, and the impulse drying pipe after the position is leaned on is connected with primary cyclone; Primary cyclone is connected with secondary cyclone; Secondary cyclone is connected with pulsed jet cloth filter, and pulsed jet cloth filter is connected with air-introduced machine, and at the air-introduced machine place adjusting valve is installed.
The natural air of wet stock after conveyer and heating gets into drier simultaneously, and the two is fully mixed because the caloic exchange area is big, thereby reaches the purpose of evaporation drying in a short period of time.Dried finished products is discharged from cyclone separator, and the sub-fraction micro mist is obtained recycling by cyclone dust collectors or sack cleaner.
Dipulse pneumatic drier of the present invention adopts the air pulse pipe as enhanced heat exchange structure, and through changing the relative velocity between material and the thermal medium, the heat and mass transfer enhancement process realizes removing rapidly of material moisture content.

Fig. 1 is the structure chart of dipulse pneumatic drier of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
As shown in Figure 1, dipulse pneumatic drier of the present invention comprises cyclone cluster 1, air cleaner 2, steam heater 3, feeder 4, several impulse drying pipes 5, primary cyclone 6, secondary cyclone 7, pulsed jet cloth filter 8, air-introduced machine 9; Wherein cyclone cluster 1 is connected with air cleaner 2; Air cleaner 2 is connected with steam heater 3, and steam heater 3 is connected with feeder 4, and feeder 4 is connected with several impulse drying pipes 5; Between several impulse drying pipes 5, connect through heating tube 11; Impulse drying pipe 5 after the position is leaned on is connected with primary cyclone 6, and primary cyclone 6 is connected with secondary cyclone 7, and secondary cyclone 7 is connected with pulsed jet cloth filter 8; Pulsed jet cloth filter 8 is connected with air-introduced machine 9, and at air-introduced machine 9 places adjusting valve 12 is installed.
The natural air of wet stock after conveyer and heating gets into drier simultaneously, and the two is fully mixed because the caloic exchange area is big, thereby reaches the purpose of evaporation drying in a short period of time.Dried finished products is discharged from cyclone separator, and the sub-fraction micro mist is obtained recycling by cyclone dust collectors or sack cleaner.
Dipulse pneumatic drier of the present invention adopts the air pulse pipe as enhanced heat exchange structure, and through changing the relative velocity between material and the thermal medium, the heat and mass transfer enhancement process realizes removing rapidly of material moisture content.
