Definitions
- the present device relates to equipment and methods for the removal of scale, rust, oxide films, organic lubricants, various impurities and surface impregnations on the surface of metal products by means of arc discharges in vacuum.
- the process can be used in iron and non-ferrous metallurgy plants, in the manufacture and processing of metal strip and strip, pipes, wide range rolled goods, wires, machinery, and any repair plant, in the petroleum and gas industry for the removal of resin - Paraffin deposits are used in pipes and equipment.
- the ablation cleaning is a short-term effect of plasma plasma-generated cold plasma having a temperature of between 6,000 ° C and 20,000 ° C and an energy density of 10 11 W / m 2 on the surface to be cleaned.
- Such a cleaning process takes place with a high cleaning performance. It is weather-independent and environmentally friendly because all molecules of the organic compounds dissociate completely or partially under the action of high-speed plasma flow within the stated temperature range. That is, these molecules break down into their constituents: C, O 2 , H 2 O, and other atoms. As a result of recombination (subsequent combustion) these form For their part, atoms excited the simplest safe combustion products, such as CO 2 and H 2 O, from composite carcinogenic molecules.
- the existing jet generators for generating the cold plasma are not suitable for ablation-based surface cleaning methods due to their shortcomings.
- Their major shortcomings are a small diameter and a short reach of the cold plasma jet flowing out of the nozzle. This is due to the high cooling rate of the plasma jet both the length and the diameter and thus is reflected in a high temperature gradient of the length and the diameter of the cold plasma jet after.
- the plasma jet Since the plasma jet is the working part of a plasma tool, its small dimensions, 30 to 60 mm in length, retain the actual applicability of the plasma tool, reduce its performance, and require high scanning accuracy of the plasma jet on the surface during cleaning.
- the size is important here in principle. So is z. B. the radial temperature gradient between 1000 and 2000 ° C / mm at a radius of 6 to 4 mm. Even the slightest error of ⁇ 0.5 mm in the plasma jet scan may cause fusion or burn through of the surface to be cleaned.
- ZAO PETROPLASMA Pulplasma Company
- the inventors of ZAO PETROPLASMA have developed two-chamber jet plasma crowns and created composite plasma-forming working bodies based on hydrocarbon liquids and gases. These make it possible to generate plasma jets with a particle velocity of up to 800 m / s, a temperature of between 3,000 ° C and 20,000 ° C and a length of up to 500 mm with a diameter of up to 40 mm.
- plasma beams with a low temperature gradient of the beams of both their length and the diameter and with large dimensions are generated both in length and in diameter.
- the composition of the plasma is environmentally friendly, which has been proven by numerous tests.
- thermochemical processes in the plasma were realized with a two-chamber design. Thanks to these thermochemical processes, the jet plasma with its blurred boundaries has become “warmer” (due to the small temperature gradient, the beam diameter and the beam length after). As a result, the melting and burning of the surface to be cleaned are avoided. This greatly simplifies the equipment needed for scanning the surface of the workpieces to be treated by the plasma jet and lowers its price.
- the combination of the arc heating of the plasma-forming, consisting of hydrocarbons working body with their dissociation and with the subsequent release of heat energy in the outflowing beam due to the chemical combustion reactions of the hydrocarbon atoms and molecules in their recombination causes the beam both in diameter and in the Length gets bigger.
- the use of hydrocarbons as a plasma-forming body significantly affects the energy properties (efficiency) of the hydrocarbon plasma guns and does not give the required service life. This can be achieved by a very high rate of electrode removal to explain. Such rapid electrode removal is mainly due to the higher thermal conductivity and heat capacity of the hydrocarbon cold plasma ( AM Zalesskiy, Electric Interruption Arc, ML .: Gos.
- the lowering of the mass-medium temperature of the plasma jet is achieved in that the cold plasma jet is mixed with the combustion products in the combustion chamber. Due to the chemical combustion energy, the combustion products can not be hotter than 3500 ° C, since it is not possible to avoid the thermal dissociation reactions.
- the dissociation is responsible for stopping the rise in the temperature of the combustion products at 3500 ° C ( GB Sinyarev, MV Dobrovol'skiy, Liquid Engines, M .: Gosoboronizdat, 1955, p. 62 ).
- the afterburning of the oxygen-containing cold plasma in the jet nozzle always causes an increase in the speed of the outflowing jet. This increases the efficiency of ablation-based surface cleaning with the Plasmatron.
- the plasmatron jet When the plasmatron jet is used to remove old coatings on the workpiece surface, it is sometimes useful to add flammable gases and airflow to the work zone for cleaning to maintain the stoichiometric and high temperature combustion of cleaning waste products. Because the high-temperature combustion with excess oxygen is environmentally friendly (does not give carcinogenic molecules) as a smoldering combustion, such. B. waste incineration.
- the arc plasma for surface treatment with supply channels (lines) is provided to supply air and combustibles. The supply takes place in parallel with the jet flowing out of the nozzle or cuts it.
- the plasmatron additionally contains extinguishing agent supply channels (water, steam, etc.) to supply them, if necessary, in parallel with the effluent jet of the composite plasma and the combustion products, if there is a risk of fire in the surface cleaning zone. This stops the supply of the plasmatron with all other components.
- extinguishing agent supply channels water, steam, etc.
- the arc plasma is equipped with more than one handle (with at least two handles) and controls mounted on it to manually operate the arc plasma generator.
- it is provided with brackets to allow its mounting on the handling devices of robots.
- the Plasmatron is gas-tight, has non-conductive outer coverings and consists of materials that allow it to operate in a wide range of temperature and humidity.
- the Plasmatron can also be operated under water, because the physical processes underlying its function also make such an operating mode possible.
- the Plasmatron For operation under water, the Plasmatron is first turned on in the countryside and then submerged.
- Fig. 2 shows the Plasmatron with nozzle view.
- the outflow openings for the components K 1 and K 3 are arranged concentrically around the outflowing jet of the plasma and the products of combustion.
- the purpose of the surface treatment arc plasma cartridge is to produce a high temperature and high velocity jet having a temperature between 3000 and 8000 ° C.
- the diameter and length of the jet F ( Fig. 1 ) These are the conventional Lichtbogenplasmatronen, z. B. after the prototype "PLASMABOHRER PB-40" exceed.
- the plasmatron contains two logically combined gas heating chambers, namely an arc chamber 3 and a combustion chamber 4.
- the arc plasma according to the invention consists of a water-cooled cathode assembly 8, a water-cooled anode assembly 2, these assemblies being protected by an insulator 1
- the jet nozzle 9 has an extendable attachment nozzle 5.
- the cathode assembly 8 has an insertable emission part 6 made of zirconium or hafnium.
- a swirl generator 7 of the plasma-forming working body is arranged.
- the potential of the power supply (in Fig. 1 not shown) is applied to the cathode assembly 8 and the anode assembly 2.
- the oxygen-containing plasma-forming working body (oxidizer) is fed to the arc chamber 3 via the swirl generator 7.
- an electric discharge is ignited.
- the electrical discharge forms under the action of the vortex of the plasma-forming working body after the swirl generator 7 in the arc chamber 3, a current-carrying channel in the burning zone of the arc discharge A.
- This current-conducting channel closes with the anode zone of the discharge E the circle in the anode assembly 2 on the surface of the stabilizing heel H.
- the stabilizing heel H is intended to avoid a negative effect, the so-called arc bridging, in plasma lobes. This effect leads to unwanted fluctuations in the arc and the arc discharge.
- the plasma-forming working body passes the discharge column of the discharge A, heats up very strongly, ionizes and turns into the cold plasma. Thereafter, the cold plasma enters the mixing zone B.
- zones B and C in the combustion chamber 4 intensive mixing of the oxygen-containing plasma and the molecules and atoms of the K 1 component of the hydrocarbon-containing fuel is achieved.
- zone D the conversion of the gas heat energy into the kinetic beam energy occurs, ie, depending on the nozzle profile, the beam accelerates F to sonic or supersonic speed.
- zone D the conversion of the gas heat energy into the kinetic beam energy occurs, ie, depending on the nozzle profile, the beam accelerates F to sonic or supersonic speed.
- z the treatment of the workpiece surfaces.
- the combustion chamber 4 and the arc chamber 3 in Fig. 1 Lengthwise comparable.
- the combustion chamber 4 is two to three times shorter than the arc chamber 3, because at temperatures above 3000 ° C, the combustion processes run slightly different than the usual combustion; they are much faster and more intense ( GB Sinyarev, MV Dobrovol'skiy, Liquid Engines, M .: Oborongiz, 1955, p. 62 ).
- the recombination processes proceed in the outflowing jet F, whereby its dimensions exceed the equally powerful plasma jet of the plasmatron, both the length and the diameter, by 5 to 10 times.
- the plasmatron In addition to the plasma-forming working body and the second fuel component K 1 (oxidizer and fuel), the plasmatron still has channels to other components K 2 , K 3 , etc. the outgoing jet F or parallel (coaxial) supply it.
- One of these components is provided to sustain the combustion reactions, e.g. During the removal of asphalt, resin, paraffin deposits in riser tubes in the surface cleaning zone.
- compressed air or oxygen are used as K 2 . This method is used effectively in outdoor and especially in the inner surface cleaning of the riser pipes.
- Another component that can or may be supplied via such channels is a gas or liquid that suppresses burning or eliminates (neutralizes) harmful properties of the combustion products.
- So z. B. suppresses the formation of CO by addition of air or oxygen.
- the supply of z. B. neutral gases suppresses the unwanted burning of impurities to be removed or eliminates any resulting fire.
- the use of the extendable attachment nozzle 5 increases the effectiveness of these measures.
- the Plasmatron housing, the cable and the supply lines of the Plasmatrons and the connections are sealed and allow it to be used for surface treatment under water.
- the Plasmatron is switched on before immersion.
- the K 1 component used was propane, alcohol, liquid paraffin, diesel oil and kerosene.
