Efficient protective agent special for gas pump

Abstract

The invention relates to an efficient protective agent special for a gas pump. The efficient protective agent is prepared from the compositions in percentage by weight: 10-30% of bromination cetyl pyridine, 5-15% citrate, 15-30% sodium lignosulfonate, 5-10% of sodium gluconate, 10-20% of imidazoline quaternary ammonium salt, 5-15% of benzotriazole, and 10-50% water. Under dispersal, lattice deformation, threshold value effect and other actions of the sodium lignosulfonate, the bromination cetyl pyridine and the sodium gluconate, the solubility of calcium carbonate and magnesium carbonate in ahigh-turbidity gas pump water seal cooling system is greatly increased, and thus the serious problem of scale formation of the gas pump can be solved. Under the action of negative pole corrosion inhibition of the imidazoline quaternary ammonium salt, the citrate, the sodium gluconate, and the benzotriazole, a compact deposited film is rapidly formed in metal surface, the serious corrosion of metal, particularly, carbon steel and other gas pump body equipment materials caused by various corrosive ions is reduced, and thus the problem of corrosion in the long-term high-temperature operation is solved.

Description

Technical field [0001] The invention relates to the technical field of auxiliary products for mining, in particular to a high-efficiency protective agent special for gas pumps. Background technique [0002] Due to the influence of the process, the operation of the gas exhaust system of the coal mine requires the use of water seals and cooling to ensure the operation of the gas pump. In particular, it is necessary to ensure the stable operation of the gas pump exhaust system throughout the year. In this case, there is serious corrosion and serious scaling. The problem of high temperature underground and corrosion of equipment, this situation is a long-term problem that many coal mine gas pump exhaust systems have been difficult to solve. Electroplating or spraying an anti-corrosion coating on the surface of the pump body is a common solution, but the above methods cannot solve the problem of scaling, and the anti-corrosion coating will cause certain environmental pollution and was...

[0002] Due to the influence of the process, the gas exhaust system of the coal mine requires the use of water seals and cooling to ensure the operation of the gas pump. In particular, it is necessary to ensure the stable operation of the gas pump exhaust system throughout the year. In this case, there are severe corrosion and serious scaling. The problem of high temperature underground and the corrosion of equipment, this situation is a problem that has been difficult to solve for many coal mine gas pump exhaust systems for a long time

Electroplating or spraying anti-corrosion coating on the surface of the pump body is a common solution, but the above methods cannot solve the problem of scaling, and the anti-corrosion coating will cause certain environmental pollution and waste
