Abstract

The utility model relates to an oil pipe descaling device which removes the dirt on the inner wall of an oil pipe with explosive impact mode, and an emission pillbox and two combustible sand boxes which have combustible agent and sand grains are arranged in the middle of a linear explosives strip, wherein the two combustible sand boxes are separately positioned on the two ends of the emission pillbox, and one end of the linear explosive strip is connected with a detonator through a connector. Detonation waves generated by explosives instantaneously impact the dirt layer to cause rust scale to drop off, and the ignited mission pillbox and combustible sand boxes cause the pressure in the pipe to increase rapidly and discharge the shed rust dirt out of the pipe and clean the pipe wall.

Description

The oil pipe stain eliminating device

Technical field

The utility model relates to a kind of oil pipe stain eliminating device that adopts the blast impulse mode to remove the tube inner wall dirt, also is applicable to the scale removal of other inner-walls of duct.

Prior art

At present, the scale removal of the scale removal of inner-walls of duct, particularly oil pipeline is a headachy problem always.Chinese patent CN2339325 discloses a kind of ash pipe apparatus for eliminating sludge, and it is outside pipe explosive to be set, and sets up overcoat again between explosive and the pipe outer wall, utilizes the shock wave vibrations ash pipe that is produced behind the explosive initiation, and black dirt is come off.But this device adopts the outer detonating charge of pipe, and is dangerous operation in, and explosive explodes outside managing in addition, and the effective rate of utilization of its energy is lower, and the thick dirt of some densifications is difficult to removing.Also the someone adopts hot high pressure water law wash oil pipe, but this method efficient is low, and is expensive big, and can't remove some abundant calcium strontium barium salts.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of oil pipe stain eliminating device that can remove abundant dirt layer in the oil pipe is provided.

The technical solution that addresses the above problem is: the oil pipe stain eliminating device that is provided, comprise explosive, said explosive is the linear explosive bar, in being provided with emission medicine box and two, the stage casing of linear explosive bar adorns the burning sand box of flammable medicament and sand grains, wherein two burning sand boxes lay respectively at the two ends of launching medicine box, and an end of linear explosive bar links to each other with detonator by connector.During use this device is put into oil pipe, the linear explosive bar that detonates, the detonation wave of explosive charge moment generation impacts the dirt layer, and continuous shaking steel pipe inwall, and rust deposite is come off.The emission medicine box that ignites again during explosive charge ignites again immediately and burns the sand box, and the pipe internal pressure is raise rapidly, and the rust deposite that comes off is with outside the pipe inner high voltage thermal current discharge pipe, simultaneously by burning sand cleaning tube wall.

Compared with prior art the utility model is because explosive is in the steel pipe implode, so use simple to operate, safety, it is little to consume energy, and clear quality is good.The wax layer not only can be removed, and fine and close rust deposite, grease more than 3 millimeters can be removed.

Description of drawings

Accompanying drawing is a structure chart of the present utility model.

The specific embodiment

As shown in the figure: linear explosive bar 1 adopts commercially available explosive bar, and its stage casing is provided with emission medicine box 2, and the both sides of emission medicine box 2 respectively connect a burning sand box 3, and emission medicine box 2 and burning sand box 3 are tubular, and they are sleeved on the linear explosive bar 1.Dress black powder or other commercially available propellant powder in the emission medicine box 2, its burning velocity is lower than the explosion velocity of linear explosive bar 1, but can produce a large amount of gas.Adorn the mixture of flammable medicament and sand grains in the burning sand box, flammable medicament adopts commercially available delay powder.One end of linear explosive bar 1 links to each other with detonator 5 by a connector 4.As long as this device is placed in the steel pipe, detonating charge gets final product during scale removal.

Claims

1, a kind of oil pipe stain eliminating device, comprise explosive, it is characterized in that said explosive is linear explosive bar (1), in establishing emission medicine box (2) and two, the stage casing of linear explosive bar (1) adorns the burning sand box (3) of flammable medicament and sand grains, wherein two burning sand boxes (3) lay respectively at the two ends of emission medicine box (2), and an end of linear explosive bar links to each other with detonator (5) by connector (4).

2, oil pipe stain eliminating device as claimed in claim 1 is characterized in that said emission medicine box (2) and burning sand box (3) are tubular, and they are sleeved on the linear explosive bar (1).
