Problems solved by technology

Among them, physical cleaning mainly includes manual cleaning, rubber ball cleaning and high-pressure water jet cleaning. The three cleaning methods have their own disadvantages in varying degrees: manual cleaning can only remove soft dirt and a small amount of hard dirt, and the removal is not thorough. High strength; rubber ball cleaning can only remove soft dirt, but cannot work on formed hard dirt; high-pressure water jet

Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0035] Such as figure 1 As shown, a low-corrosion and high-purity chemical cleaning method for condensers is especially suitable for low-corrosion and high-purity chemical cleaning methods for condensers whose pipe materials are stainless steel, carbon steel, and copper. The condenser must be cleaned before cleaning Stop the machine, close the inlet and outlet valves of circulating water, install blind plates and inlet and outlet flanges, and install exhaust pipes with a diameter of 50 mm on the uppermost part of the condenser water chambers on both sides to remove a large amount of gas generated during cleaning. Then, To establish a temporary cleaning system, the inlet pipes 30, 31 and outlet pipes 30', 31' of the condenser 3 are connected to t...

Abstract

The invention discloses a low-corrosion and high-cleanness chemical cleaning method for condenser. The cleaning process of the method is shown as follows: performing primary washing and leakage detection, adding a disinfectant slime remover for cleaning soft deposits, adding a Lan-826 multipurpose pickling inhibitor and a reducing agent to perform corrosion inhibition treatment, adding aGJ-2E rust removal and descaling agent and a Lan-826 multipurpose pickling inhibitor for removing hard scale, neutralizing with an alkaline cleaning neutralizer, and passivating or pre-filming. The method has the beneficial effects that the biological slime of the condenser is fully cleaned; the used corrosion inhibition method can be used for reducing the corrosion of the pickling cleaning agent to the pipeline of the condenser, and improving the service life of the pipeline of the condenser; meanwhile, the used pickling cleaning agent can be used for fully cleaning the pipeline hard scale, and the pipeline is cleaned more drastically; the cleaning time is short, the descaling efficiency is high, the labor intensity is low, the technology is simple, and the operation parameter of the cleaned set mainly achieves the plate rating.

Description

technical field [0001] The invention relates to a low-corrosion and high-purity chemical cleaning method for a condenser. Background technique [0002] Condenser (also known as condenser) is widely used in industrial production as heat exchange equipment. It uses circulating cooling water to cool another liquid or gas. After one to two years of operation, the condenser has the problem of scaling. This not only directly affects the effect of cooling and heat exchange, but also causes problems such as slowing down of production progress, increase of gas pressure, increase of energy consumption, and decrease of power generation. Therefore, cleaning the dirt of the condenser and restoring the heat exchange effect of the condenser, It is of great significance for industrial enterprises to improve production efficiency, save energy and safe production. [0003] The prior art for cleaning the condenser is mainly divided into physical cleaning and chemical cleaning. Among them, ph...
