Embodiment 1

[0013] First prepare a 3% (weight) hydrochloric acid solution with water, then add a corrosion inhibitor accounting for 3‰ (weight) of the total amount of the hydrochloric acid solution to obtain a cleaning solution, heat the cleaning solution to 65 ° C, and clean the surface of the water gas compressor. The valve plate covered with alkaline debris is soaked in the cleaning solution for 40 minutes, and finally the soaked parts are rinsed with clean water and then air-dried naturally. After the treatment, the surface of the valve plate restores its original smoothness.

Embodiment 2

[0015] First prepare a 2% (weight) hydrochloric acid solution with water, then add a corrosion inhibitor accounting for 2‰ (weight) of the total amount of the hydrochloric acid solution to obtain a cleaning solution, heat the cleaning solution to 60 ° C, and clean the surface of the water gas compressor. The air valve covered with alkaline debris is soaked in the cleaning solution for 50 minutes, and finally the soaked parts are rinsed with clean water and then air-dried naturally. The surface of the treated air valve is restored to its original finish.

[0016] Example 2

[0017] First prepare a 5% (weight) hydrochloric acid solution with water, then add a corrosion inhibitor accounting for 4‰ (weight) of the total amount of the hydrochloric acid solution to obtain a cleaning solution, heat the cleaning solution to 70 ° C, and clean the surface of the water gas compressor. The valve plate covered with alkaline debris is soaked in the cleaning solution for 30 minutes, and fin...

Abstract

The invention relates to a chemical cleaning method for removing dirt on parts (such as an air valve and a valve plate) of a water gas compressor, and the method solves the problem that the surfaces of the parts of the existing water gas compressor, such as the air valve, the valve plate and the like, are easily covered by alkali dirt, which directly influences the normal operation of the compressor. The adopted technical scheme is as follows: preparing 2-5wt% of hydrochloric acid solution with soft water, and adding corrosion inhibitor which accounts for 0.2-0.5 wt% of the total amount of the hydrochloric acid solution, thus obtaining cleaning solution; and heating the cleaning solution to 60DEG C to 70DEG C, and immersing the parts of the water gas compressor into the cleaning solution.The chemical cleaning method can remove instrument operation damage on the surface of the parts and keep original finish of the surfaces of the parts, time and labor are saved, the cost is reduced, and nearly ** yuan can be saved by a single unit per month.

Description

technical field [0001] The invention relates to a chemical cleaning method for removing sundries in parts (such as gas valves and valve plates) of water gas compressors. Background technique [0002] The surface of parts of water gas compressor, such as gas valve and valve plate, is easily covered by alkaline debris, which directly affects its normal operation. The current method is usually to use acid-base neutralization chemical cleaning method to remove impurities on the surface of parts, and Corrosion inhibitors are used to protect metal structures, but there are problems such as cumbersome procedures. Contents of the invention [0003] The invention provides a chemical cleaning method for removing sundries of water gas compressor parts (such as gas valves and valve plates), which can eliminate mechanical damage on the surface of the parts, maintain the original smoothness of the parts surface, save time and effort, and reduce costs. reduce. [0004] A chemical clean...
