Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 to 4, a spray drying tower comprises a tower body 1, wherein the upper end of the tower body 1 is provided with a liquid material inlet 11, the liquid material inlet 11 extends into the tower body and is connected with a spray nozzle 2, and the liquid material inlet 11 extends out of the tower body and is connected with a high-pressure pump; the lower end of the column body 1 is provided with a feed opening 12.
The annular wall of the tower body 1 is provided with at least one air outlet 13, generally a plurality of air outlets; the outer seal cladding of tower body 1 rampart is provided with heat preservation clamp cover 3, and heat preservation clamp cover 3 covers the upper portion, middle part and the lower part position of tower body rampart to heat preservation clamp cover 3 has seted up the perforating hole corresponding to the position of air outlet 13, is equipped with hot-blast entry 4 on the heat preservation clamp cover 3, and hot-blast entry 4 is linked together with a plurality of air outlet 13.
Thus, hot air enters from the hot air inlet 4 (hot air can be generated by multiple ways without limitation), firstly enters the heat-insulating jacket, and enters the tower body from the plurality of air outlets 13 in the process of filling the heat-insulating jacket. This spray drying tower's design, in other words, a plurality of air outlets have been seted up on the tower body itself, and the outer sealed cladding of tower body has the heat preservation to press from both sides the cover, realized evenly preheating whole tower body, from this, a plurality of air outlets cooperation can increase material and hot-blast contact time, make material drying efficiency uprise, the temperature that can make the tower wall simultaneously is more balanced, can avoid going up the material and caking at the tower wall, and the heat that the material accumulation conduction got off when the bottom can continue the drying, make the material drying more thorough.
This air outlet 13 is equipped with outer annular plate 14 of following of integral type towards the direction in the tower body outside, and outer annular plate 14's inner wall along has seted up the screw thread, and outer annular plate 14 is followed by the perforating hole and is stretched into in heat preservation jacket 3, and outer annular plate 14's external diameter size is the same with the diameter size of perforating hole outward. For the sealing effect, the gap between the outer peripheral ring plate 14 and the insulating jacket 3 can be filled with a gasket.
The outer edge ring plate 14 may be threaded with the ring wall seal 5. The design of the structure can realize the secondary utilization of the spray drying tower, when all the outer edge ring plates are in threaded connection with the ring wall sealing element (as shown in figure 2), the spray drying tower is converted into a closed tower body, and other processes such as storage, stirring, filtering, cleaning and the like can be realized in the closed tower body; when a part of the outer edge ring plate is in threaded connection with a ring wall sealing element (as shown in figure 3), a part of air outlets of the spray drying tower can also serve as inlets/outlets for use, and the application range is very flexible.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the right of the present invention should not be limited thereby, and therefore, modifications, equivalent changes, improvements, etc. made in the claims of the present invention are still included in the scope of the present invention.
