Problems solved by technology
[0004] Some separation technologies have been used in the treatment process at home and abroad, but they have not been widely used due to the disadvantages of cumbersome operation and high operating costs. In some similar turbid circulating water systems, adding scale inhibitors and dispersants is a simple method. However, due to the single addition of chemicals, it cannot meet the scale inhibition and dispersion requirements of complex water quality conditions such as different temperature ranges and different suspended solids content in the system at the same time, so the water treatment effect of the system has not yet guaranteed the process equipment. long run

Abstract
The invention discloses a gray water dispersion scale inhibitor, which comprises the following components in weight percent: 10-30% of acrylic acid, 10-25% of methyl acrylate, 10-25% of ethyl acrylate, 10-20% Hydroxypropyl acrylate and 10-20% anaerobic desalted water. At the same time, the invention also discloses a preparation method of the above-mentioned dispersant. The invention does not contain phosphorus, has excellent scale inhibition performance and stronger dispersibility.
Description
technical field [0001] The invention belongs to the field of petrochemical industry, and in particular relates to a gray water dispersant and a preparation method thereof. Background technique [0002] The coal gasification process is a highly water-consuming process. From the perspective of environmental protection and economy, the only choice is to recycle the gas washing water of the coal gasification plant and minimize the effluent treatment! However, due to the wide range of water temperature and pressure in the washing water recycling system (temperature 50-280°C, pressure 1-8Mpa), the system has three-phase material and energy transfer of gas, liquid and solid, and the working conditions are complex. Calcium hardness, alkalinity and suspended matter content are very high (suspended matter is basically above 1500mg / L, pH value is above 12), and the concentration increases with the continuous reuse of water, and scaling of the washing water recycling system is inevitabl...
