Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the embodiments and the drawings.

[0027] The mechanism for preventing the spray drying tower from sticking to the wall according to the present invention, such as figure 1 As shown, the device includes an outer cylinder 21 with an air inlet 19 and an air outlet 20; and a suction port 22 provided on the outer cylinder for providing anti-sticking material in the outer cylinder 21; wherein, in the outer cylinder 21 The flowing airflow carries the anti-sticking material and flows out through the air outlet 20. The outer cylinder 21 may be made of metal or heat-resistant material, and the outer cylinder 21 made of the material can meet the requirements of heat-resistant wind. After the gas with anti-sticking materials enters the drying tower cylinder 2 (such as image 3 ), it can be dispersed to various parts in the drying tower to improve the phenomenon of sticky materials sticking to the wall. The...

Abstract

The invention provides a mechanism and a method for preventing wall adhesion of a spray drying tower. The mechanism comprises an outer cylinder and a suction port, wherein the outer cylinder is provided with an air inlet and an air outlet; the suction port is formed in the outer cylinder and is used for providing an adhesion preventing material to the inside of the outer cylinder; and air current flowing in the outer cylinder can carry the adhesion preventing material to flow out through the air outlet. The invention also provides a device for preventing the wall adhesion of the spray drying tower. The device comprises the mechanism and an air current distributor connected with the air outlet of the outer cylinder. The invention further provides the method for preventing the wall adhesion of the spray drying tower. According to the method, air current and the adhesion preventing material are fed into a spray drying area by the device.

Description

Technical field [0001] The invention relates to the field of chemical equipment, more specifically to the field of material dispersion equipment. Background technique [0002] The product prepared by spray drying of viscous materials is granular but not smooth, which will cause sticky walls and agglomeration, which will cause tower blockage. If it is not cleaned in time, normal production will not be maintained. For this type of material, intermittent operation is usually used in the spray drying industry to manually clean it. The production efficiency of the device is not high, and the work intensity of the operator is high. [0003] At present, the industry usually uses secondary drying or secondary blending methods to make the product smooth and meet the final requirements of the finished product. The secondary drying is to further reduce the moisture content of the product at a higher temperature (higher than the temperature in the drying tower), and it is suitable for non-he...
