Problems solved by technology

[0004] The purpose of the present invention is to provide a descaling pipeline and its use method to solve the problem that the existing descaling pipeline needs to be shut down for cleaning when negative pressure is used, the positive pressure hose is easy to be damaged, and the manufacturing cost of the pipeline is high. The valves connected between the pipelines are prone to scaling, resulting in unsatisfactory descaling effects

Embodiment

[0023] Wet-process phosphoric acid semi-aqueous phosphoric acid transport descaling pipeline with a diameter of 80mm, refer to figure 1 .

[0024] Including the first peristaltic pump 1, feeding pipe 2, feeding hose 3, rubber check valve 6, second peristaltic pump 7, flange 8, discharge pipe 9, first time relay 10, second time relay 11 And hard pipe 12, all are fixed by flange 8 between the connected pipe and pipe.

[0025] The pipe hose 3 is made of aramid fiber braided reinforced EPDM pipe, with a flange 8 at the end of the pipe, and the inner diameter of the pipe hose 3 is 80 mm; Connected hard pipe 12, hard pipe 12 adopts polypropylene injection molding pipe, with flange 8 at both ends of the pipe, every 200mm on the hard pipe 12 is a vent hole 13 with a diameter of 2mm, and the outer diameter of the delivery hose 3 is the same as The inner diameter of the hard pipe 12 is matched, and the air holes 13 on the hard pipe 12 are sealed and communicated with one end of the di...

Abstract

The invention provides a scale removal pipeline and a using method thereof and belongs to the technical field of conveying pipelines. The scale removal pipeline comprises a first peristaltic pump, a feeding pipe and a material conveying hose. One end of the feeding pipe extends into a liquid material pool, and the other end of the feeding pipe communicates with the feeding end of a hose of the first peristaltic pump. One end of the material conveying hose communicates with the discharging end of the hose of the first peristaltic pump, the other end of the material conveying hose extends the position above a discharging pool or into the discharging pool, and a rubber check valve is arranged at the other end of the material conveying hose. The problems that during actual application of an existing scale removal pipeline, machine halt needs to be conducted for clearing when negative pressure is adopted, the hose is prone to being damaged when positive pressure is adopted, pipeline manufacturing cost is high, and valves connected between the pipelines are prone to scaling, so that the scale removal effect is not ideal are solved.

Description

technical field [0001] The invention relates to the technical field of transportation pipelines, in particular to industrial wet-process phosphoric acid, crude oil transportation or other materials prone to scaling. Background technique [0002] In the oil and gas or phosphoric acid industry, pipelines are often used to transport crude oil or phosphoric acid. The transported substances often contain impurities such as organic matter, H2S, CO2, bacteria, and sediment. Scale is formed. After the pipeline is scaled, the diameter of the pipeline will be reduced, and the flow cross-sectional area will be reduced, resulting in pressure damage, reduced displacement and pipeline blockage. Pipeline blockage and scaling will also induce local corrosion of the pipeline, resulting in frequent leakage or even perforation of the pipeline, resulting in destructive accidents. Therefore, chemical descaling, high-pressure water jet descaling, mechanical descaling, ultrasonic descaling, etc. ...
