Descaling agent and cleaning system for descaling boiler by using same

Abstract

The invention discloses a descaling agent and a cleaning system for descaling a boiler by using the descaling agent. The cleaning system comprises a boiler and a cleaning mechanism arranged in the boiler, the cleaning mechanism comprises a first fixing plate, a second fixing plate, a guide rail, a driving mechanism and a cleaning assembly, and the first fixing plate and the second fixing plate are arranged up and down; the diameter of the first fixing plate is larger than that of a boiler opening, the diameter of the second fixing plate is smaller than that of the boiler opening, the guide rail is vertically arranged, the two ends of the guide rail are perpendicularly connected with the first fixing plate and the second fixing plate correspondingly, the cleaning assembly is movably installed on the guide rail and used for cleaning and descaling the inner wall of the boiler, and the driving mechanism is connected with the cleaning assembly and drives the cleaning assembly to slide on the guide rail. The cleaning assembly sprays a descaling agent to the inner wall of the boiler through the multiple high-pressure sprayers, the descaling agent reacts with dirt on the inner wall of the boiler, a scrubbing assembly scrubs the part, sprayed with the descaling agent, of the inner wall of the boiler, the dirt can be effectively brushed away, and the cleaning system is thorough in descaling, obvious in descaling effect and suitable for various kinds of carbon steel and stainless steel system equipment.

Description

technical field [0001] The invention relates to the technical field of boiler descaling, in particular to a descaling agent and a cleaning system for descaling boilers using the descaling agent. Background technique [0002] Boilers currently on the market include hot air stoves, water heaters, and steam stoves. Mechanical energy or electric energy, etc.; after the boiler has been used for a long time, a large amount of dirt will be generated on the inner wall of the boiler, which will greatly reduce the thermal conductivity of the boiler and waste fuel. At present, the cleaning agents for the chemical cleaning of carbonate scale and silicate scale in the boiler system mainly use inorganic strong acids such as hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, and organic acids such as EDTA, glycolic acid, sulfamic acid, oxalic acid, and citric acid. acid. Hydrochloric acid, hydrofluoric acid, sulfuric acid and nitric acid are the most common cleaning agents i...

AI Technical Summary

Problems solved by technology

Hydrochloric acid, hydrofluoric acid, sulfuric acid and nitric acid are the most common cleaning agents in chemical cleaning. They have obvious effects on carbonate scale and short cleaning time. At the beginning of the development of chemical cleaning industry, they have a wide supply and low price, so they have become the descaling agents. The preferred cleaning agent for chemical cleaning, but with the improvement of environmental protection and hazardous chemical management and control, hazardous chemical reporting and business licenses are required for procurement, the transportation cost has increased, and the price advantage no longer exists. At the same time, in terms of process use, hydrochloric acid, Hydrofluoric acid, sulfuric acid and nitric acid are unsafe and environmentally friendly during the cleaning process. They have poor cleaning effect on sulfate scale and silicon oxide, and their applicability to boiler materials is relatively simple.

EDTA, glycolic acid, sulfamic acid, oxalic acid, citric acid and other organic acids have lower toxicity and less corrosion than inorganic strong acids, and have wide applicability for cleaning carbonates and various oxides. To 80 ℃, the cleaning conditions are relatively harsh, and the cleaning time is long, the cleaning rate of sulfate and silicate scale is not good, and the cleaning effect is not obvious
