Abstract

The invention discloses a descaling corrosion inhibitor and a preparation method thereof. The descaling corrosion inhibitor is prepared from the following raw materials in percentage by mass: 20-25% of imidazoline, 10-20% of hexamine, 3-5% of ammonium hydroxide, 10-15% of ethylene diamine tetra (methylene phosphonic acid) sodium, 9-15% of ethyl alcohol, 10-15% of penta sodium salt of amino trimethylene phosphonic acid and 5-40% of water. The descaling corrosion inhibitor is suitable for blast furnace gas residual pressure recovery turbine power generation equipment, and can effectively solve the problems that a spraying nozzle is blocked, and scales are formed to corrode blades.

Description

technical field [0001] The invention belongs to the technical field of descaling, and relates to a sustained-release agent, especially a descaling and corrosion inhibitor dedicated to wet TRT equipment and a preparation method thereof. Background technique [0002] TRT is an energy device that uses the pressure energy of the blast furnace top gas, expands the gas pressure energy into mechanical energy after expansion by the turbine, and then drives the generator to generate electricity by the turbine, and finally converts the mechanical energy into electrical energy. TRT power generation belongs to the secondary recovery of energy, does not consume fuel, has low power generation cost, and has a significant effect of energy recovery, which has important practical significance for energy saving and consumption reduction. [0003] Wet TRT equipment relies on spraying a large amount of water to reduce the dust content in the gas and meet the requirements for secondary utilizatio...
