Description

Technical Field

[0001] The invention relates to reactor outer surface spraying equipment and a method thereof, and in particular to a multi-station reactor spraying device and a processing method thereof. Background Art

[0002] Reactors are suitable for use in high-voltage or low-voltage components. Common voltages range from hundreds of volts to hundreds of kilovolts. They are mostly used in scenarios such as substations, distribution cabinets, and electric locomotives. They require a dry, ventilated environment to avoid moisture or dust contamination and can withstand high or low temperatures. Outdoor equipment must be waterproof and corrosion-resistant, while indoor equipment must be dustproof. Explosion-proof designs are required in some scenarios. They are connected in series in the circuit to suppress short-circuit current, balance load fluctuations, and improve grid stability. They work with capacitors to form a filter circuit, absorb harmonic currents, improve power quality, provide inductive reactive power in AC systems, adjust the grid power factor, and reduce energy consumption. In DC systems, they store magnetic field energy or are used for dynamic voltage regulation to limit inrush current when capacitor banks are switched on and off, thereby extending equipment life. The outer surface of the reactor needs to be sprayed when in use, using spray equipment for the spraying operation.

[0004] Although the prior art can effectively improve the uniformity of coating coverage on the inner surface of the package and avoid coating waste, the amount of coating cannot be controlled according to the area of the reactor, resulting in excessive waste of the sprayed liquid. Summary of the Invention

[0014] The following steps are included

[0015] Step 1: Roughening

[0016] An automated shot blasting machine is used to roughen the outer surface of the reactor. The shot blasting particle size is 0.2 to 0.5 mm. After treatment, the surface roughness reaches Ra 30 to 50 μm to enhance the adhesion of the coating. The reactor or local areas are cleaned with a high-pressure water jet (pressure 8 to 12 MPa).

[0017] Step 2: Clean and degrease

[0018] Use a neutral environmentally friendly cleaning agent (pH 6-8) with ultrasonic cleaning equipment to remove surface oil, rust and dust.

[0019] Step 3: Protective shielding

[0020] For non-sprayed areas (such as terminals and nameplates), use high-temperature resistant masking tape (temperature resistance ≥ 200°C) or peelable coating to cover them.

[0021] Step 4: Spraying the outer surface of the reactor

[0022] The spraying liquid includes: epoxy zinc-rich primer, mica iron oxide anti-rust paint topcoat, and polyurethane weathering paint. The epoxy zinc-rich primer, mica iron oxide anti-rust paint topcoat, and polyurethane weathering paint are mixed and then sprayed by spraying equipment;

[0023] When spraying, a spraying mechanical head is used to spray the surface of the reactor. The spraying distance is 200-300mm, and the film thickness is controlled as follows: the single-layer dry film thickness is 40-60μm, and the total thickness is ≥120μm.

[0025] Side inspection plates are set on both sides of the spraying station. The wide-angle camera detects the spraying uniformity in real time through color difference analysis. Combined with the feedback of the control system, closed-loop management of the spraying quality is realized to improve the yield rate. The primary dynamic centrifugal separation relies on the adjustable guide plate to efficiently remove large particles. The intermediate electrostatic adsorption layer captures submicron particles. The terminal catalytic oxidation layer (Pt / TiO2) decomposes organic matter, and the exhaust gas treatment is more thorough. The double-tower heat storage device recovers the waste heat of the flue gas, and the combustion chamber secondary incinerates the residual pollutants, making the emissions cleaner and in line with environmental protection standards. Environmentally friendly coatings such as epoxy zinc-rich primer and polyurethane weathering paint are used to reduce volatile organic compound emissions and take into account both anti-corrosion and weathering resistance.

[0026] From roughening to spraying parameters, all process data is uploaded to the control center in real time to support parameter optimization and fault tracing. The color difference images taken by the wide-angle camera, the stereo images taken by the binocular camera and other data are analyzed through algorithms to generate spraying quality reports to guide process improvements.

[0027] The side positioning plates, trigger components, inspection plates, etc. all adopt a modular design and can be quickly adjusted to accommodate reactors of different specifications, reducing equipment modification costs. Shot blasting is combined with high-pressure water jets to take into account both the overall processing of large workpieces and local fine cleaning, resulting in more uniform surface treatment. Electromagnetic adsorption replaces mechanical fixtures to reduce equipment wear and lower consumables costs. The spray fume recovery system is equipped with an explosion-proof design, and automated operation reduces the risk of manual exposure to toxic paint or exhaust gases.
