Description

Spray drying tower with self-cleaning function Technical Field The invention relates to the technical field of spray drying towers, in particular to a spray drying tower with a self-cleaning function. Background The spray drying tower is a continuous drying device widely applied to the chemical industry field, and the core application of the spray drying tower is to quickly convert liquid materials (such as solution, emulsion and suspension) into powdery, granular or hollow spherical solid products. The working principle is based on the high synergy of mass transfer and heat transfer, and the material is dispersed into fine fog drops through the atomizer, so that the specific surface area is greatly increased, and meanwhile, clean air heated to high temperature is introduced from the top of the tower and is instantaneously mixed with the fog drops in the tower body. In the extremely short time of the contact of the hot air and the fog drops, the moisture is quickly vaporized, the heavier solid particles are settled to the bottom of the tower after drying and are collected, and the tail gas containing a large amount of fine powder is discharged and then the solid powder and the waste gas are separated and recovered through a cyclone separator or a bag-type dust collector. In the spray drying process, the emulsion is dispersed into fine mist droplets by an atomizer and sprayed out. During the downward movement of the mist droplets and the mixing with the hot air, part of the mist droplets will move to the inner wall of the drying tower and adhere to the surface thereof. Along with the continuous vaporization of the moisture, the solid matters formed after the fog drops are dried are gradually adhered to the inner wall and are continuously heated under the continuous action of hot air, so that the quality problems of coking, color change and the like are finally caused. For this reason, existing spray drying towers are often equipped with a wall-sticking material cleaning function to ensure product quality and stable operation of the equipment. The existing spray drying tower gradually exposes the defects in the use process, and the defects are mainly shown in the following aspects: The wall-sticking material cleaning mode has more limitations, and particularly, the wall-sticking material cleaning mode of the existing spray drying tower mainly comprises four modes of mechanical knocking, high-pressure water jet cleaning, airflow impact and automatic scraping by a scraper. The automatic scraping of the scraper can continuously scrape the inner wall of the tower body through the rotating scraper structure arranged in the tower body, the online cleaning in operation can be realized, the material accumulation is easy to occur on the main body of the scraper structure, the quality problems such as coking and color change still occur after the accumulated materials are heated for a long time, and therefore, the conventional wall-sticking material cleaning mode has more limitations in the aspects of cleaning effect, operation continuity and cleaning structure body cleaning, and greatly influences the use effect of the equipment. In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed. Disclosure of Invention Aiming at the defects in the prior art, the invention aims to provide the spray drying tower with the self-cleaning function, the cleaning mode adopted by the spray drying tower can clean wall-adhered materials in a state that equipment continuously operates, the influence degree of the viscosity of the materials on the cleaning effect is extremely small, the stable and reliable cleaning process is ensured, and meanwhile, the cleaning structure body has the self-cleaning function, so that the problem of accumulation and deterioration of the materials on the surface of the cleaning structure body is effectively avoided, therefore, the limitation of the cleaning mode is extremely small, and the use effect and the operation reliability of the equipment are remarkably improved. In order to solve the problems, the invention provides the following technical scheme: The utility model provides a spray drying tower with self-cleaning function, includes the loading board, the fixed bottom plate that is equipped with in loading board top, the fixed tower shell that is equipped with in bottom plate top, the fixed roof that is equipped with in tower shell inside, the roof bottom has four square boards of fixed setting along circumference equipartition, square board bottom and bottom plate fixed connection, adjacent two all be equipped with the bounding wall that horizontal migration set up between the square board, the top and the lateral wall of bounding wall correspond and offset with roof and square board friction, square board and bounding wall enclose and close and form dry cavity, the bounding wall tip runs through the clearance board that is equipped with
