It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the present application, and is not intended to be exhaustive or to limit the scope of the application.
Referring to fig. 1, the present application provides a fully automatic spray drying tower assembly (hereinafter, sometimes simply referred to as "spray drying tower assembly") with dust recovery capability that is capable of converting a product, such as a dye, from a slurry form to a granular form. It is to be understood that the arrows in fig. 1 indicate the direction of movement of the substance (e.g., dye, gas).
The spray drying tower assembly comprises a tower body 11 and a collector 13. A spray drying head 18 is provided at the inner side of the top area of the tower body 11, and a dye in a slurry form may be atomized by the spray drying head 18 and then introduced into the tower body 11. The top area of the tower 11 may also be provided with openings for the input of hot air. It will be appreciated that the atomised dye can be formed into a particulate form when exposed to hot air and subsequently collected by the collector 13. Illustratively, the collector 13 may be an automated packing scale capable of automatically quantitatively collecting and dispensing dye particles. The spray drying tower assembly may comprise a collecting pipe 22, by means of which collecting pipe 22 the collector 13 may be connected to the bottom of the tower 11.

In the tower body 11, part of the dye has small particle size and is dispersed in the gas. The first fan 16 may be an induced draft fan, which may be connected to the tower body 11 through a first wind pipe 19, for forming a negative pressure to draw gas out of the tower body 11. The cyclone 14 is used for separating dye particles doped in the gas, and the cyclone 14 may be disposed between the tower body 11 and the first fan 16 (specifically, the cyclone 14 may be disposed in a pipeline connecting the tower body 11 and the first fan 16), and connected to the tower body 11 through the second fan 17 and the second air pipe 21. The second fan 17 may be a blower, and after the dye is separated by the cyclone 14, the dye may be sent back to the tower body 11 by the second fan 17. The connection position of the second air duct 21 and the tower body 11 can be the bottom of the tower body 11.
In the prior art, most of dyes are directly discharged and packaged, and the dyes with smaller particle sizes can scatter along with gas, so that the product yield is reduced, the environment is polluted, and the production cost is increased. And this application after the dyestuff granule in the isolate gas, blow back the dyestuff granule to tower body 11, realized the dust and retrieved the function, reduced the dust content in the waste gas, increased the output of product.
In one embodiment of the present application, the spray drying tower assembly further comprises a third air duct 20, the collector 13 may be connected to the first air duct 19 via the third air duct 20, and a connection point of the third air duct 20 and the first air duct 19 may be located between the cyclone 14 and the tower body 11, so as to achieve dust absorption in the charging stage and improve safety of a working scene.
In an embodiment of the present application, a dust collector 15, such as a bag-type dust collector, may be further disposed between the cyclone 14 and the first fan 16, so as to further reduce the dust content in the gas sucked by the first fan 16 and reduce the emission of pollutants.
In an embodiment of the application, a tower pressure sensor 12 may be arranged in the tower 11. For example, a pressure setpoint P1 may be set, and the first fan 16 is controlled to increase or decrease the suction level when the tower pressure sensor 12 measures a value greater or less than P1. For example, the output of the tower pressure sensor 12 may be connected to a controller of the first fan 16. The tower pressure sensor 12 transmits a corresponding signal to the controller of the first fan 16, and the first fan 16 increases or decreases the suction level according to the given signal, so that the actual pressure in the tower 11 is always stabilized at P1, and the moisture content and quality of the product are stabilized.
It will be appreciated that it is also possible to maintain the actual pressure in the tower 11 within a predetermined pressure range, rather than at a specific pressure point.
In one embodiment of the present application, the spray drying tower assembly may further comprise a steam regulating valve 7, an air blower 8 and a heat exchanger 9. Steam can be used as a heat source of the heat exchanger 9 and is input into the heat exchanger 9 through the steam adjusting valve 7. The air blower 8 may be a blower, and wind sent by the blower is heated by the heat exchanger 9 and is input to the tower 11.

For example, a temperature set point T may be set, and the steam regulating valve 7 is controlled to decrease or increase the valve opening degree when the temperature sensor 10 detects that the temperature at the top of the tower body 11 is greater or less than T. For example, the output end of the temperature sensor 10 may be connected to the controller of the steam adjusting valve 7, the temperature sensor 10 transmits a corresponding signal to the controller of the steam adjusting valve 7, and the steam adjusting valve 7 decreases or increases the valve opening degree according to a given signal, so that the heat generated by the heat exchanger 9 decreases or increases, and the temperature of the air input to the tower body 11 by the air blower 8 decreases or increases accordingly, thereby stabilizing the actual temperature at the top of the tower body 11 at the set value T.
It will be appreciated that it is also possible to maintain the actual temperature in the tower 11 within a predetermined temperature range, instead of a specific temperature point.
It will be appreciated that the overhead temperature is an important factor affecting product quality. The top temperature of the drying tower in the current market is manually controlled, so that the temperature is unstable and fluctuates greatly, the control efficiency is low, and the production cost is high; and the heat of the pipeline is very large, and potential safety hazards exist in manual control. The application provides a spray drying tower subassembly adopts automatic control's form, and is comparatively accurate, and the product quality who obtains is stable, has saved the manual work, manufacturing cost and potential safety hazard greatly reduced.
In one embodiment of the present application, the spray drying tower assembly may further comprise a slurry storage tank 3, a high pressure pump 4, and a pneumatic valve 6.

Illustratively, a pressure set value P2 may be set, and the air-operated valve 6 can be controlled to open or close when the line pressure sensor 5 detects that the line pressure at its position is greater than or less than P2. For example, the output of the line pressure sensor 5 may be connected to the controller of the pneumatic valve 6. When the measured value of the line pressure sensor 5 is greater or less than P2, the line pressure sensor 5 transmits a corresponding signal to the controller of the air-operated valve 6, and the air-operated valve 6 is opened or closed.
It can be understood that most of dye drying adopts a pressure type drying tower, and the drying tower needs the slurry to reach a certain pressure value before atomization drying is carried out, otherwise, the phenomenon of tower flowing can occur. The height of the pressure type drying tower is about 50 meters, and the manual valve opening mode is often adopted in the past, so that the production efficiency is low, and the labor is consumed. The application provides a spray drying tower subassembly adopts automatic control's form, need not artifical manual switching valve, and production efficiency is higher, and the potential safety hazard is lower.
In one embodiment of the present application, the spray drying tower assembly may further comprise a transfer pump 1 and a filter 2. The transfer pump 1 may be a screw pump for transferring the slurry of the product to the slurry storage tank 3. A filter 2 may be provided between the transfer pump 1 and the slurry storage tank 3 for filtering out solid impurities in the slurry.
A level sensor 31 may be provided inside the slurry storage tank 3 for determining the liquid level inside the slurry storage tank 3. The liquid level sensor 31 may be a pressure sensor, and the liquid level is converted and calculated by measuring the liquid pressure. A level set point may be set and the transfer pump 1 is controlled to operate or stop when the slurry level is below or above the level set point. For example, the output of the fill level sensor 31 can be connected to a control of the delivery pump 1. When the slurry liquid level is lower than or reaches the liquid level set value, the liquid level sensor 31 transmits a corresponding signal to the controller of the delivery pump 1, and the delivery pump 1 works or stops working according to a given signal, so that the slurry in a certain liquid level is kept in the slurry storage tank 3 constantly.
It will be appreciated that two level sensors 31 of different heights may be provided. In addition, the liquid level in the slurry storage tank 3 may be made to be in a predetermined height range, instead of a specific height value.
It will be appreciated that there is a need to ensure that there is always slurry inside the slurry reservoir 3 during the spray drying process. In the past, a manual control mode is adopted, and the manual control mode has the defects that: the situation that slurry overflows or is insufficient often happens when manpower is consumed, the spray drying process is influenced, and if the slurry overflows, environmental pollution can be caused, and the product yield is reduced. This application passes through level sensor 31 and the cooperation of delivery pump 1, realizes the automatic control of liquid level in the thick liquids hold up tank 3, has solved above-mentioned problem.
While the foregoing is directed to the preferred embodiment of the present application, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the application.
