Environmentally-friendly composite rust mud stripping agent and preparation method thereof

Abstract

The invention belongs to the technical field of cleaning of an industrial circulating water system, and particularly discloses an environmentally-friendly composite rust mud stripping agent and a preparation method thereof. The stripping agent mainly comprises the following components in percentage by weight: 5-8 percent of tetradecyl dimethyl benzyl ammonium bromide, 2-5 percent of sodium polyacrylate and the balance of water. The preparation method comprises the following steps of: (1) adding the tetradecyl dimethyl benzyl ammonium bromide and the sodium polyacrylate into a preparation container and stirring until the mixture is uniform after addition is finished; and (2) adding water into (1) to fix volume and stirring until the mixture is uniform to prepare a finished product. Througha large number of scientific experiments and internal practical application of several years, the rust mud stripping agent has a good stripping effect on rust mud and biological slime, and metal corrosion and environmental pollution can be avoided.

Description

technical field [0001] The invention belongs to the technical field of cleaning of industrial circulating water systems, and in particular relates to an environment-friendly composite rust and mud stripper and a preparation method thereof. Background technique [0002] Industrial circulating water systems are widely used in electric power, metallurgy, food, medicine, central air-conditioning systems, papermaking, petrochemical and other industries, but due to the influence of environmental conditions, they are easily polluted by impurities such as bacteria, oxygen, sulfur dioxide, nitrogen oxides, and acid rain After continuous circulation, dirt such as rust mud and biological slime will gradually form on the inner wall of the pipe network equipment, which will increase the resistance of the circulating water and reduce the flow rate, and even cause rust mud to corrode the pipeline and biological slime to block the equipment, resulting in Enterprises must increase the number...

Problems solved by technology

[0002] Industrial circulating water systems are widely used in electric power, metallurgy, food, medicine, central air-conditioning systems, papermaking, petrochemical and other industries, but due to the influence of environmental conditions, they are easily polluted by impurities such as bacteria, oxygen, sulfur dioxide, nitrogen oxides, and acid rain After continuous circulation, dirt such as rust mud and biological slime will gradually form on the inner wall of the pipe network equipment, which will increase the resistance of the circulating water and reduce the flow rate, and even cause rust mud to corrode the pipeline and biological slime to block the equipment, resulting in Enterprises must increase the number of circulating pumps and replenish a large amount of water, resulting in a large amount of additional loss of hydropower resources

When it is so serious that the equipment cannot operate, it must be shut down for maintenance or replacement, which will cause greater losses to the production and operation of the enterprise.

[0003] The usual solution is to manually discharge the circulating water to reduce the content of pollutants in the water, which further leads to the waste of water resources and the increase of management costs.

The more critical problem is that rust sludge and biological slime have high viscosity and strong adhesion, and it is difficult to completely remove them by sewage discharge after sticking to the inner wall of pipes or equipment. Some enterprises have to stop production and use manual and mechanical methods to clean the equipment. Dredging not only affects production, but also easily damages equipment
