Problems solved by technology

However, practice has proved that the devices and processes at that time did not fully take into account the particularity of the physical indicators of molten sebacic acid
Therefore, the technical indicators including the control precision of the sebacic acid product particle size and the reduction of energy consumption are not ideal

Embodiment Construction

[0018] Can have a further understanding of the process of the present invention with reference to the accompanying drawings. In this process, saturated steam is used as the processing heat source of industrial sebacic acid products, and the redesigned process is realized by the following procedures;

[0019] ①Choose qualified industrial sebacic acid products and add them to a melting tank with stirring, and pass saturated steam into the melting tank to heat and melt sebacic acid,

[0020] ② The sebacic acid that is stirred uniformly after melting is transported to the centrifugal chamber 7 of the centrifugal sprayer by means of the heat preservation pipeline 8,

[0021] ③The molten sebacic acid is atomized and sprayed out by means of the evenly distributed injection holes on the side wall of the centrifugal chamber and the high-speed rotating centrifugal chamber,

[0022] ④Introduce the atomized molten sebacic acid into the countercurrent settling tower, and complete cooling,...

Abstract

The present invention relates to an improvement on sebacic acid melting-spraying granulation process and its equipment. Said process is implemented by adopting the following procedures: (1), making the sebacic acid product be added into a melting kettle with stirrer, introducing saturated steam, heating and melting; (2), feeding the molten sebacic acid into a centrifugal chamber of centrifugal spraying machine by means of heat-insulating conveying pipeline; (3), utilizing jet holes which are uniformly distributed on the side wall of said centrifugal chamber and high-speed rotated centrifugal chamber to make the molten sebacic acid be ejected; (4), introducing the atomized molten sebacic acid into a countercurrent settling tower and undergoing the processes of cooling, forming and drying; and (5), feeding the formal products collected by trapper onto a vibration sieve, sorting and packaging so as to obtain the invented finished product. The improved equipment is a vertical tower-type structure, tower top is equipped with an air draught hole, a buffer chamber settling cavity and a trapper, and the lower portion of tower body is equipped with an air inlet structure.

Description

technical field [0001] The invention relates to a processing technology of industrial raw material sebacic acid and special equipment thereof. Specifically, it is a sebacic acid melt spray granulation process and its device. Background technique [0002] Sebacic acid is an important organic chemical raw material, which is widely used in polymer products as plasticizers, adhesives or other modified fillers. The subsequent process in the currently used sebacic acid production process is to centrifuge and dehydrate the crystalline sebacic acid, and then dry it with hot air to form a powdery sebacic acid product. Because the formed powder is too fine, it is very easy to form a dust explosion; especially in the process of weighting, filling and stirring, it will cause the powder to fly. It not only pollutes the environment, deteriorates working conditions, but also loses products and causes waste. Since the application environment of sebacic acid is a special organic solvent c...
