Description

TECHNICAL FIELD

[0001] The utility model relates to technical diesel antiwear coolant field especially a cooling device for diesel antiwear agent. BACKGROUND

[0002] With the implementation of the national six diesel standard, domestic sulfur reduction technologies such as hydrogen treatment and hydrogen cracking are adopted, which greatly reduces the sulfur content of diesel, and the sulfur content of diesel is reduced to below 10PPM. However, because the lubricity in diesel mainly comes from sulfur-containing substances, reducing sulfur content also reduces the diesel lubricity index. Due to the poor lubricity of low-sulfur diesel, the high-pressure oil pump and injector of the diesel engine are rapidly worn and fail. Therefore, low-sulfur diesel and ultra-low-sulfur diesel usually use lubricity additives (diesel antiwear agents) to improve the lubricity of diesel.

[0003] For most diesel, fatty acid type diesel antiwear agent can meet the main index requirements, and its low-cost competitive advantage is obvious. Fatty acid type diesel antiwear agent is usually made by using a reaction kettle for a long time high-temperature reaction, and the finished diesel antiwear agent usually needs a cooling process.

[0004] As disclosed in Chinese utility model patent CN202022802340.X, a cooling device for diesel antiwear agent, the high-temperature finished antiwear agent is in contact with the feed pipe in the spiral preheating pipe to exchange heat, the raw materials in the feed pipe are preheated, and the antiwear agent in the cooling pipe is further cooled by the air pump blowing, so as to achieve the purpose of cooling. However, the contact area between the spiral preheating pipe and the feed pipe in the disclosed document is too small, so the heat exchange efficiency is limited.

[0005] As disclosed in Chinese utility model patent CN201420087617.7, a viscous liquid heat exchanger conducts heat exchange through heat conduction medium in a closed shell, and makes the high-temperature viscous liquid and the low-temperature viscous liquid flow in the spiral coil, so as to have high heat exchange efficiency and save considerable heat. However, the feed spiral pipe in the disclosed document has only one, which cannot meet the feeding demand of raw materials with different properties. If multiple raw materials share one spiral pipe without being fully mixed, serious situations such as blockage may occur. Moreover, the preheating and cooling efficiency of a single spiral feed pipe is far inferior to that of multiple spiral feed pipes. UTILITY MODEL CONTENTS
