Description

Production of dacron DTY finish is with corrosion-resistant high temperature resistant toper reation kettle

Technical Field

The invention belongs to the technical field of conical reaction kettles, and particularly relates to a corrosion-resistant and high-temperature-resistant conical reaction kettle for producing a polyester DTY oiling agent.

Background

The finish can be classified into a polyester finish, a polyamide finish, a polypropylene finish, a spandex finish, and the like according to the type of the fiber.

The finish can be divided into pre-spinning finish, post-spinning finish and the like according to the sequence of processing procedures.

The oil agent can be classified into a POY oil agent, a DTY oil agent, and the like according to the properties of the processing step.

In the high-speed polyester filament yarn POY-DTY spinning process, two kinds of oil agents, namely a spinning oil agent and a post-processing oil agent, are needed. The post-processing oil is used for meeting the requirements of the cylinder forming and post-processing weaving process of the DTY. Different DTY oil solutions have different influences on the unwinding property, the bundling property, the friction property, the antistatic property and the like of the fibers.

The broad understanding of the reaction kettle is that the reaction kettle is a container for physical or chemical reaction, and the heating, evaporation, cooling and low-speed mixing functions required by the process are realized through the structural design and parameter configuration of the container.

The reaction kettle is widely applied to pressure vessels for petroleum, chemical engineering, rubber, pesticides, dyes, medicines and foods, and is used for completing technological processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and the like, such as a reactor, a reaction kettle, a decomposition kettle, a polymerization kettle and the like; the material is generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloy and other composite materials.

For the production of polyester DTY oil agent, the following patent documents mainly exist at home at present:

as disclosed in patent publication nos.: CN209333737U discloses a conical reaction kettle, which is divided into a cylindrical section and a conical section. The main stirring blade makes the materials in the cylinder section fully mixed and reacted. The auxiliary stirring blade enables the newly added materials at the top of the cylinder to be fully mixed and reacted. The materials in the conical section are fully mixed and reacted through the first blade, the second blade and the third blade; meanwhile, under the action of the spring, the first blade, the second blade and the third blade which are arranged on the sleeve float up and down within a certain elastic force range, so that the stirring area is increased, and the quality of a product obtained by reaction is improved. The sizes of the first blade, the second blade and the third blade are gradually decreased and are the same as the diameters of the cross sections of the conical sections from the top end to the bottom end, so that the shapes of the kettle bodies are matched, and the whole space is uniformly stirred. However, the conical reaction kettle provided by the patent lacks a sandwich structure, so that the internal heat preservation and heating effects of the kettle body are poor.
