Description

Technical Field

[0001] The invention relates to the technical field of antistatic agent preparation, in particular to an antistatic agent preparation device. Background Art

[0002] The main components of petroleum and its products are hydrocarbon compounds, which have extremely low electrical conductivity. After desulfurization and denitrification, the electrical conductivity of fuel oil is even worse. Especially for light oil products such as gasoline, diesel, and kerosene, due to their high resistivity, they are more likely to generate and accumulate a large amount of static charge during production, processing, and use. If they encounter flammable gases, they are very likely to generate sparks and explode, causing economic losses and casualties. Adding an appropriate amount of antistatic agent to oil products is the most important and convenient way to solve the electrostatic disaster; Polyamine-polysulfone composite antistatic agent is widely used because of its excellent antistatic performance and applicability to most hydrocarbon fuels. The preparation device of polyamine-polysulfone composite antistatic agent mainly includes polyamine reaction, polysulfone reaction, compound processing and finished product packaging.

The added auxiliary material can be quickly premixed with the reaction solution, the auxiliary material will not pile up together, and it is easy to stir and mix.

[0018] 4. While the auxiliary material adding mechanism sprays the auxiliary material into the premixing mechanism in a high-pressure manner, the high-pressure airflow can be used to blow the mixing paddle to rotate. When the mixing paddle rotates, the auxiliary material and the reaction solution can be quickly stirred and mixed, which can effectively improve the premixing effect.

[0019] 5.

When in use, the water inlet 203 and the water outlet 204 are respectively connected to the water inlet pipe and the water outlet pipe. Hot water is circulated into the temperature control channel 202 through the water inlet pipe and the water outlet pipe to heat the material in the mixing tank 2. Conversely, cold water is circulated into the temperature control channel 202 through the water inlet pipe and the water outlet pipe to cool the material in the mixing tank 2. When nitrogen is transported into the mixing tank 2 for nitrogen replacement or sulfur dioxide gas is transported into the mixing tank 2 for polysulfone reaction, the nitrogen and sulfur dioxide gas are discharged from the air outlet 806 on the first stirring mechanism 8. Bubbles are generated when the nitrogen and sulfur dioxide gas are discharged. The bubbles can be used to blow the solution in the mixing tank 2 to speed up the mixing of the solution, which can not only improve the reaction efficiency, but also the bubbles generated when the nitrogen is discharged can take away the water vapor in the solution, which can improve the vacuum dehydration efficiency; The vacuum pump 401 on the vacuum dehydration mechanism 4 can be used to evacuate the mixing tank 2, and the materials can be vacuum dehydrated in the polyamine reaction process. In the polysulfone reaction process, the remaining sulfur dioxide gas can be discharged from the mixing tank 2, and the discharged gas can be absorbed and processed by the tail gas absorption tower 404, and the water vapor in the discharged gas can be condensed by the condenser 402.
