Abstract

The invention discloses a scale remover for pipelines of a geothermal system and a preparation method thereof. The scale remover comprises the following components by mass: 1 to 15 parts of a metal material protective agent, 2 to 20 parts of a protein decomposition agent, 5 to 25 parts of a synergist, 10 to 55 parts of acid, 5 to 30 parts of a degerming agent, 3 to 15 parts of a corrosion inhibitor and 2 to 12 parts of a scale inhibitor. According to the scale remover for pipelines of the geothermal system and the preparation method thereof in the invention, through improvement of the composition of the scale remover and increase of protein clastic enzyme in the composition, a variety of bacteria such as a plurality of pathogenic bacteria like Escherichia coli, Clostridium botulinum, Salmonella and Shigella produced during usage of the geothermal pipelines can be effectively removed; and in consideration of the fact that a plurality of protein clastic enzymes are suitable for living in a neutral environment, the protein clastic enzyme is ultimately added in the preparation process, so high activity of the protein clastic enzyme is guaranteed, and good descaling effect is obtained.

Description

technical field [0001] The invention relates to a descaling agent, in particular to a geothermal system pipeline descaling agent and a preparation method thereof. Background technique [0002] Water floor heating uses hot water with a temperature not higher than 60°C as the heat medium, circulates in the heating pipes buried in the filling layer below the ground, heats the entire floor, and supplies heat to the room through the ground through radiation and convective heat transfer. A way of heating. [0003] The main equipment part includes heating wall-hung boiler, heating main pipe, manifold, heating floor coil, thermostat and so on. Large-sized houses are also equipped with heating circulating water pumps (for pressurization), thermostatic mixing valves (for energy saving and good comfort), etc. Auxiliary materials include: extruded board (insulation board), reflective film, floor heating staples, steel wire mesh, boundary insulation strip, stainless steel hose, ball va...
