Pipe cleaning and descaling device and descaling method

Abstract

The invention provides a pipe cleaning and descaling device and a descaling method. The pipe cleaning and descaling device comprise an inner core, wherein a plurality of steel nail belts are laid andfixed on the surface of the inner core, steel nails are fully distributed on the surface of the steel nail belts, a skin is fixed on the rest of the surface of the inner core, the skin, the steel nailbelts and the inner core are a firm whole, an air bag is arranged in the inner core, an exhaust pipe is arranged at the tail of the air bag, an automatic valve body is arranged on the exhaust pipe and used for adjusting the diameter size of the air bag, and a pressure sensor is arranged in the air bag, is in wireless connection with the automatic valve body and is used for controlling the openingand closing of the automatic valve body. According to the pipe cleaning and descaling device and the descaling method, the diameter of the equipment can be automatically changed to finish descaling,the diameter can be contracted to prevent the pipe cleaning and descaling device from being clamped inside a pipe, descaling is simple, the efficiency is high, and the descaling effect is good.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a pigging and descaling device and a descaling method. Background technique [0002] During the wet desulfurization process, the walls of the lime slurry or gypsum slurry delivery pipes will accumulate different degrees of sediments to block the pipes, and disassembly and cleaning are very complicated and cumbersome. In the past, chemical methods were generally used to descale the drainage pipes, but the chemical methods used At the same time, the water quality is polluted, the equipment is eroded, and the operation is complicated and the investment is large, which affects the normal drainage of the drainage pipes. Therefore, various types of descaling equipment have been developed on the market. [0003] Such as the announcement number CN2238092Y, the patent name is a hydraulic pipe cleaner, including skin, steel nails, steel nail belts and inner core, and several stee...

Problems solved by technology

[0004] Although this kind of hydraulic pipe cleaner is suitable for descaling of drainage pipes of different lengths and thicknesses, it is only suitable for drainage pipes with slight changes in length and thickness. will drop, and if there is stubborn scaling in the drain pipe, the hydraulic pig can easily get stuck inside the pipe

Therefore, in order to better match various types of pipeline descaling, it is necessary to set up various types of hydraulic pigs, but the cost of such settings is high in manpower and material resources, and the product utilization rate is not high, resulting in waste of resources
