Problems solved by technology

[0002] At present, in China, ethylene tar resin is made from the heavy component of ethylene tar reserved after extracting aromatic oil and industrial naphthalene from ethylene tar in an ethylene factory. The raw material is added to the stripper tank, and then the initiator is added to heat the stripper tank. The reaction is carried out under normal pressure. The temperature in the reaction is about 300°C, and the temperature of the obtained ethylene tar resin is about 300°C. The obtained ethylene tar resin products are all in the form of blocks and flakes. Great inconvenience, the packaging process wastes a lot of manpower, material resources and time, and the transportation cost is also high, resulting in an increase in the cost of ethylene tar resin products. In addition, block and flake ethylene tar resin cannot be accurately measured when used, And it is not convenient for subsequent remelting

Embodiment 1

[0040] (1) 8 tons of ethylene tar resin raw materials are pumped into the stripping tower kettle through a heavy oil pump, then 24 kg of initiator is added, the stripping tower kettle is heated, and the stripping tower vacuum unit is turned on to evacuate at the same time, so that the stripping tower can be stripped during the reaction. The temperature in the tower kettle is 180°C, the temperature at the top of the tower is 140°C, and the pressure is 0KPa. After the steam rising from the top of the stripping tower is cooled by the condenser at the top of the stripping tower, all the liquid phase enters the fuel oil receiving tank, and the liquid ethylene obtained by the reaction is The tar resin is located in the stripper kettle and reacted for 2 hours. After the reaction, turn off the vacuum unit to restore the pressure in the stripper kettle to normal pressure, and pass the ethylene tar resin into the resin through the discharge pipe at the bottom of the stripper kettle. In t...

Embodiment 2

[0044] What is different from embodiment 1 is step (1) and step (2), and step (3) is identical with embodiment 1.

[0045] (1) 18 tons of ethylene tar resin raw materials are pumped into the stripping tower kettle through a heavy oil pump, then 90 kg of initiator is added, the stripping tower kettle is heated, and the stripping tower vacuum unit is turned on to evacuate at the same time, so that the stripping tower can be stripped during the reaction. The temperature in the tower kettle is 200°C, the temperature at the top of the tower is 160°C, and the pressure is -30KPa. After the steam rising from the top of the stripping tower is cooled by the condenser at the top of the stripping tower, all the liquid phase enters the fuel oil receiving tank, and the liquid phase obtained by the reaction is The ethylene tar resin is located in the stripping tower kettle and reacted for 4 hours. After the reaction, turn off the vacuum unit to restore the pressure in the stripping tower kett...

Embodiment 3

[0048] What is different from embodiment 1 is step (1) and step (2), and step (3) is identical with embodiment 1.

[0049] (1) 10 tons of ethylene tar resin raw materials are pumped into the stripping tower still through the heavy oil pump, then add 80 kilograms of initiators, and heat the stripping tower still so that the temperature in the stripping tower still is 230 ° C in the reaction process. The top temperature is 180°C, the pressure is -60KPa, react for 7 hours to obtain ethylene tar resin, and pass the ethylene tar resin into the resin receiving tank through the discharge pipe at the bottom of the stripping column; the temperature of the ethylene tar resin obtained by polymerization is about is 225°C;

[0050] (2) Pass the cooled high temperature resistant heat transfer oil into the cooling coil in the resin receiving tank, and cool the ethylene tar resin in the resin receiving tank to a temperature of 156° C.

Abstract

The invention discloses an ethylene tar resin granulation process, which comprises the following steps of: conveying an ethylene tar resin raw material into a gas stripping tower kettle, adding an initiator into the gas stripping tower kettle, heating the gas stripping tower kettle, reacting the raw material and the initiator to obtain ethylene tar resin, and cooling the ethylene tar resin to between 150 and 160 DEG C; and introducing the cooled ethylene tar resin to a distributor of a granulator, uniformly distributing the ethylene tar resin on a steel conveyer belt below the distributor in a granular form by the distributor, and cooling the steel conveyer belt by using a cooling device below the steel conveyer belt during conveying so as to cool the ethylene tar resin into granular resin. The granulator comprises a frame, the distributor, a conveying device and the cooling device. The process can perform continuous production and operation; the obtained resin granules have uniform and regular shape and good color; the granular tar resin is convenient to pack and convey so as to greatly reduce the production cost; and the granular product is convenient for accurate measurement, is more convenient for a user to use, is easy to re-melt and greatly reduces the heat consumption.
