It is more efficient and less polluting than traditional cleaning methods.

Description

A laser-warm water combined cleaning device for the inner wall of oil pipe

technical field

The invention belongs to the field of laser cleaning, in particular to a combined laser-warm water cleaning device for the inner wall of oil pipes.

Background technique

In recent years, the domestic mainstream oil pipe cleaning methods are chemical cleaning and heating cleaning, but the chemical cleaning method will leave a large amount of chemical waste liquid after the oil pipe is cleaned, causing serious pollution to the environment; heating cleaning can clean the dirt in the oil pipe after heating The effect is not very ideal. With the enhancement of people's awareness of environmental protection, people are eager to pursue a "green" cleaning technology that is different from the traditional chemical cleaning method, has no pollution, and is harmless to the human body and the environment. Laser cleaning technology is one of them. When the laser cleans the dirt on the inner wall of the oil pipe, it can destroy the dirt attached to the inner wall of the oil pipe without damaging the inner wall of the oil pipe, and there is no chemical residue. However, some dirt falls off under the action of high-temperature laser, and even melts at high temperature. If these substances are not taken out of the oil pipe in time, they will still reattach to the inner wall of the oil pipe after they cool down, which will have a negative impact on the cleaning effect of the oil pipe. .

Contents of the invention

Aiming at the above-mentioned problems of laser cleaning in the oil pipe, the invention discloses a combined laser-warm water cleaning device for the inner wall of the oil pipe.

The technical scheme adopted in the present invention is:

A combined laser-warm water cleaning device for the inner wall of an oil pipe, comprising a laser generator, a lens, a connecting plate, an oil pipe, a reflector, a water flow channel, a laser channel, and a base, and the laser light generated by the laser generator becomes The parallel laser beam is irradiated to the reflector on the base, and is reflected at the reflector. It is emitted along the laser channel and irradiates the inner wall of the oil pipe to be cleaned. Through the rotational movement of the oil pipe, the inner wall of the oil pipe will form a ring-shaped cleaning area. The dirt in this area is heated at high temperature; while the laser is irradiating, warm water will flow out through the water flow channel to wash the inner wall of the oil pipe after laser irradiation, and remove the dirt still attached to the inner wall of the oil pipe after the inner wall of the oil pipe is melted by laser irradiation. Flushing, along with the solid dirt that has been shed by the high temperature, cools down the area of the tubing that has been irradiated by the laser.

The present invention has the following advantages when working:

1. This device can wash away the dirt melted under the laser irradiation, together with the solid dirt that falls off due to high temperature, so as to prevent the dirt from staying in the oil pipe and affecting the cleaning effect.

2. Warm water scours the inner wall of the oil pipe after laser irradiation, which can effectively reduce the temperature of the oil pipe and prevent damage to the inner wall of the oil pipe caused by continuous high temperature.

3. During the working process of the device, the water flow channel of warm water is always outside the laser channel, which can effectively cool down the device.

4. The warm water flow channel and the laser channel of the device are placed separately, which can effectively prevent the interference of the water flow on the laser and improve the working efficiency of the laser.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a laser-warm water combined cleaning device for the inner wall of the oil pipe of the present invention includes a laser generator (1), a lens (2), a connecting plate (3), an oil pipe (4), a reflector (5), a water flow channel (6), laser channel (7), base (8). The laser light generated by the laser generator (1) becomes a parallel laser beam after being collimated by the lens (2), and then irradiates the reflector (5) on the base through the laser channel (7) in the center of the device, and is captured by the reflector (5) The reflected laser is emitted through the laser channel (7) at the bottom of the device, and irradiates the inner wall of the oil pipe (4) to be cleaned, and heats the dirt on the inner wall of the oil pipe (4) at high temperature; at the same time, warm water passes through the water flow channel ( 6) Flowing out, flushing the dirt still attached to the inner wall of the oil pipe (4) after being melted by laser irradiation, and taking away together with the solid dirt that fell off due to high temperature. And cool down the oil pipe after laser irradiation.

As shown in Figure 2, the base (8), the water channel (6) and the laser channel (7) in the upper part of the device are connected together by four connecting plates (3), and the whole device is integrated for easy installation and fixing and construction.

When working, a laser-warm water combined cleaning device in the oil pipe of the present invention is inserted from the mouth of the oil pipe (4), the laser generator (1) is turned on, warm water is introduced, and the oil pipe (4) is rotated while slowly moving along the axial direction Oil pipe (4); the laser light generated by the laser generator (1) is irradiated on the lens (2), and after being collimated by the lens (2), it becomes a parallel laser beam, which is irradiated along the laser channel (7) in the center of the device On the reflector (5) installed on the base (8), the laser light reflected by the reflector (5) is emitted through the laser channel (7) at the bottom of the device, and irradiates the inner wall of the oil pipe (4) to be cleaned, because the oil pipe ( 4) Rotating continuously, a ring-shaped laser irradiation area will be formed on the inner wall, so that all the dirt on the inner wall will be destroyed under the irradiation. Since the warm water is introduced at the beginning, the warm water flows out through the water flow channel (6) while the laser is irradiated, and the area irradiated by the laser on the inner wall of the oil pipe (4) is washed away, and the inner wall of the oil pipe (4) is melted by the laser irradiation Finally, the dirt still attached to the inner wall of the oil pipe is washed away, together with the solid dirt that has fallen off due to high temperature. The residual heat on the inner wall of the oil pipe (4) after the laser irradiation is also taken away under the washing of the warm water, reducing the temperature of the oil pipe (4) after being irradiated by the laser. When the axial movement of a whole oil pipe (4) is completed, turn off the laser, continue to feed warm water, then return the oil pipe to the starting point, and use warm water to clean the inner wall of the oil pipe (4) for the second time, when the oil pipe ( 4) When you reach the starting point, complete the cleaning work and turn off the warm water.
