Description

Technical Field

[0001] The utility model relates to the technical field of dosing, and more specifically to a petrochemical dosing device. Background Art

[0002] In the petrochemical production process, special chemical agents need to be added through dosing devices to improve the physical and chemical properties of oil products, such as increasing the octane number of fuel, the cetane number of diesel, or enhancing the antioxidant and anti-wear properties of lubricants, and ensuring that the agents can be added at a precise concentration and a stable rate.

[0003] The existing dosing device stores the chemical agents to be added in the agent storage tank, and then transports the agents in the storage tank to the oil product at a precise flow rate through a metering pump, thereby realizing the dosing operation of petrochemicals and improving the properties of the oil product to make it perform better.

[0004] In the actual use of the prior art, the metering pump is the core component of the dosing device, which is responsible for delivering the reagent in the storage tank to the oil product at a precise flow rate. Since the metering pump is easily affected by excessive output, unstable pressure or abnormal sound operation during use, the addition amount is inaccurate, affecting the quality of the final product. Therefore, a petrochemical dosing device is proposed. Utility Model Content
