Problems solved by technology

[0002] The spray dryer heats the air and sprays it onto the atomized object to be dried, and increases the surface area of ​​the object to be dried through the atomized small particles, thereby enabling rapid drying; in the actual drying process, the air is often suspended due to Dust, although the air is filtered after entering the spray dryer, it is still unavoidable for dust with a small particle diameter, and at the same time, the requirements for the ambient air of the equipment are increased

Embodiment 1

[0032] see figure 1 Shown, the present invention is a kind of air separation device that is used for spray dryer, comprises dedusting equipment 1, ozonolysis equipment 2, water tank 3 and drying equipment 4, and air successively from dedusting equipment 1, ozonolysis equipment 2, water tank 3 and The drying equipment 4 enters the spray dryer.

[0033] like Figure 2-4 As shown, the dust removal equipment 1 includes a ventilation box 101 and a dust collection box 106. One surface of the ventilation box 101 is connected to the dust collection box 106. Side boxes 102 are respectively arranged on both sides of the ventilation box 101. Two opposite inner surfaces of the ventilation box 101 are provided with ionizers. Plate 103, one surface of side box 102 is provided with adsorption plate 104, one surface of adsorption plate 104 is provided with peeling knife 105, one surface of ventilation box 101 is provided with dust outlet, the position of dust outlet is adapted to the positio...

Embodiment 2

[0042] see Figure 1-10 As shown, the present invention is an air separation device for a spray dryer. Its working principle is: after the air enters the device, it first passes through the dust removal device 1, and applies a DC high voltage on the ionization plate 103 of the dust removal device 1, and passes through the strong The electric field ionizes the dust in the air, and then the ionized dust is adsorbed to the surface of the board through the adsorption plate 104, and then the dust on the surface of the adsorption plate 104 is scraped into the dust collection box 106 by the stripping knife 105, and the oxygen in the air passes through After the dust removal equipment 1, ozone will be generated under the action of a strong electric field. In order to prevent the strong oxidative properties of ozone from affecting the substances in the spray dryer, the ozone is decomposed by the ozonolysis equipment 2, and the ozone is decomposed by ultraviolet or infrared rays. Improv...

Abstract

The invention discloses an air separation device for a spray dryer, and relates to the technical field of dryers. The air separation device comprises a dust removal device, an ozone decomposition device, a water tank and a drying device, wherein air sequentially enters the spray dryer from the dust removal device, the ozone decomposition device, the water tank and the drying device. Dust in the air is adsorbed and filtered by arranging of the dust removal device; the ozone decomposition device is arranged to eliminate and decompose ozone generated in the dust removal device; oxidation influence of ozone on a dried object is reduced, residual ozone and dust in the air are adsorbed by arranging the water tank, redundant moisture in the air is adsorbed by arranging of the drying device, the drying effect of the spray dryer is improved, and the requirement of the spray dryer for the environment air quality is lowered.

Description

technical field [0001] The invention belongs to the technical field of dryers, in particular to an air separation device used in spray dryers. Background technique [0002] The spray dryer heats the air and sprays it onto the atomized object to be dried, and increases the surface area of ​​the object to be dried through the atomized small particles, thereby enabling rapid drying; in the actual drying process, the air is often suspended due to Although the air is filtered after entering the spray dryer, it is still unavoidable for dust with a small particle diameter, and at the same time, the requirements for the ambient air of the equipment are increased. Contents of the invention [0003] The object of the present invention is to provide an air separation device for a spray dryer, which solves the problems mentioned in the background art. [0004] In order to solve the problems of the technologies described above, the present invention is achieved through the following t...
