Abstract

The invention relates to a method of cleaning an inner wall of a pipeline. The method comprises the following steps of (1) carrying out ungrease treatment on the pipeline; (2) filling cleaning fluid into a high-pressure water gun; (3) cleaning through the high-pressure water gun; (4) cleaning through a hairbrush; (5) cleaning through high-pressure pure water; (6) carrying out drying treatment; (7) carrying out internal inspection on the pipeline. According to the method, more than once cleaning process is performed, so that the inner wall of the pipeline can obtain a good molding surface and cleanliness, and dust and some metal particles inside and outside the pipeline can be effectively removed to obtain a clean and dry work piece surface.

Description

A kind of inner-walls of duct cleaning method
Technical field
The present invention relates to a kind of cleaning method, relate to a kind of inner-walls of duct cleaning method in particular.
Background technology
Pipeline is the device of fluid for carrying gas, liquid or band solid particle be connected into pipe, pipe connector and valve etc.Usually, fluid, after the superchargings such as air blast, compressor, pump and boiler, flows to low pressure place from the high pressure of pipeline, also can utilize pressure or the gravity transfer of fluid self.Having many uses of pipeline is general, be mainly used in feedwater, draining, heat supply, give gas, long distance delivery oil and natural gas, agricultural irrigation, in hydraulic engineering and various commercial plant.
But because the greasy filth in long-term use pipe, rust deposite solidification cause former caliber to diminish; In long-term pipe, silt deposit generation hydrogen sulfide gas causes environmental pollution and easily causes and fires; Acid in waste water, alkaloid substance easily produce corrosion to duct wall; The irregular removing of foreign matter in pipeline causes line clogging etc., these problems all have impact on the normal use of pipeline, therefore clean pipeline, make to recover material surface itself in pipeline, have the meaningful of essence, it effectively can ensure the safety of equipment and the service life of extension device.
Chinese patent notification number CN 101767098 A discloses a kind of piping cleaning method, comprises step: A water flowing is cleaned, inject water in pipe arrangement side to be cleaned, and water is flowed out from opposite side, and the time of water flowing cleaning is no more than 30 minutes; B, compressed air drying, as injecting compressed air in described pipe arrangement, make the air-flow that formed in pipe arrangement higher than the air draught of 10m/s, at least 30 minutes dry time; C vacuum drying, the gas of discharging in described pipe arrangement, make air pressure in pipe arrangement between-0.1 to 0.2MPa, between vacuum at least 60 minutes.Although this patent can complete the cleaning to pipe arrangement, but some greases or some other alkaline matter are difficult to accomplish effective removing, and in cleaning process, make use of compressed air and vacuum drying two steps, essentiality content just does dry process to the pipe arrangement after cleaning, and the cost of input is higher.
Summary of the invention
In order to overcome above-mentioned deficiency, the technical scheme that the present invention solves is the cleaning method providing a kind of inner-walls of duct.
To achieve these goals, the present invention adopts following technical scheme:
Pipe interior cleaning method, its feature comprises the following steps:
(1) ungrease treatment is carried out to pipeline
Pipeline is put into the groove filling degreasing agent, soak 2-10min, stir pipeline 3-5 time in immersion process, then take out;
(2) cleaning fluid filled by giant
Cleaning fluid is filled in giant;
(3) giant cleaning
Giant is pushed in pipeline, hydraulic pressure 20-25kg/cm 2;
(4) hairbrush cleaning
Pipeline hairbrush cleans, scavenging period 3-5 minute;
(5) High Pressure Pure Water cleaning
The percussion of High Pressure Pure Water is utilized to complete the cleaning residual to inner-walls of duct;
(6) dry process
Nitrogen drying process is carried out in pipeline;
(7) pipe interior inspection
Internal check is carried out to dried pipeline, qualified sealing protection.
Preferably, also antifoaming agent is added with in the cleaning fluid in described giant.
Preferably, described cleaning fluid be at 20 DEG C water become with cleaning agent proportioning concentration be 6% cleaning fluid.
Preferably, the cleaning agent of described cleaning fluid is nitric acid, sulfamic acid, and corrosion inhibiter and surfactant are mixed with cleaning agent with the weight ratio of 20:70:6:4.
Advantageous Effects of the present invention is:
The present invention can ensure that inner-walls of duct obtains good molded surface and cleannes, effectively can remove the dust inside and outside pipeline and some metallic particles, obtain the surface of the work of clean dried.
