Problems solved by technology

[0004] Although some mechanical processes are currently used in China to clean them, they generally use soda ash, oily solvents, strong acids or strong alkaline cleaning agents, and they generally need to be heated or boiled during cleaning. Volatile components are difficult to rinse off, causing great harm to the environment, equipment and human body

Abstract

The invention discloses special degradable cleaning powder for an oil storage tank and a preparation method thereof and belongs to the technical field of industrial cleaning agents. The special degradable cleaning powder for the oil storage tank contains the following ingredients in parts by weight: 0.5-2 parts of theasaponin, 0.1-0.2 part of lipase, 20-28 parts of diatomite, 3-5 parts of meerschaum, 2-4 parts of soapberry, 1-3 parts of Saussurea involucrata fruit, 0.2-0.3 part of purple perilla, 0.01-0.06 part of holly essential oil, 2-4 parts of didecyl dimethyl ammonium chloride, 0.5-0.8 part of sodium citrate, 2-7 parts of penetrant and 15-30 parts of water. According to the special degradable cleaning powder for the oil storage tank, disclosed by the invention, oil dirt, wax and the like can be thoroughly and rapidly removed from an oil conveying pipeline, and the removal ratio can reach up to 97%; the raw materials do not contain strong-acid and strong-base substances, so that the special degradable cleaning powder is non-corrosive, is harmless to human bodies and is safe and environment-friendly; meanwhile, the product prepared by the method has relatively good degradability and has good stripping performance to scales.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning agents, and in particular relates to a special degradable cleaning powder for oil storage tanks and a preparation method thereof. Background technique [0002] The oil storage tank is a container for storing oil products, and it is the main equipment of the oil depot. According to the material, oil storage tanks can be divided into metal oil tanks and non-metal oil tanks; according to their location, they can be divided into underground oil tanks, semi-underground oil tanks and above-ground oil tanks; according to the installation form, they can be divided into vertical and horizontal; according to their shape, they can be divided into Cylindrical, square box and spherical. [0003] After the oil storage tank has been used for a period of time, the impurities in the crude oil will deposit on the bottom and wall of the tank, which will reduce the effective capacity of the oil storage t...
