Company: 山东世一环境科技有限公司
Product Description: RCO catalytic combustion equipment is an efficient and environmentally friendly waste gas treatment device. The following is a detailed introduction:1. Equipment OverviewDefinition: RCO catalytic combustion equipment is an organic waste gas treatment device that combines low-temperature catalytic oxidation with regenerative technology.Purpose: It is used to treat medium to high concentration organic waste gases to meet environmental emission standards.2. Working PrincipleUtilizes a high-energy ratio activated carbon adsorption bed and catalyst bed to purify organic waste gases under the action of catalysts before discharge.The activated carbon adsorption method uses porous activated carbon to adsorb pollutants from organic waste gases onto its surface for purification.Catalytic oxidation breaks or alters the chemical bonds of gas molecules with oxygen at high temperatures to eliminate toxic and harmful gases.3. Main ComponentsCatalyst Layer: Typically uses noble metal catalysts such as platinum, palladium, and rhodium, which offer high catalytic activity and stability.Combustion Chamber: After pretreatment, waste gas enters the combustion chamber, where it mixes with air and burns at high temperatures to generate thermal energy.Heat Exchanger: Thermal energy is transferred to the incoming waste gas via the heat exchanger, raising it to the combustion temperature.4. Technical FeaturesHigh Treatment Efficiency: Suitable for treating various organic waste gases, volatile organic compounds, and odorous gases.Low Energy Consumption: Utilizes recycled hot air generated from waste gas combustion to reduce production costs.Easy Operation: The catalytic combustion device operates with automatic control, and desorption and adsorption are managed by an electric control system.Low Maintenance Cost: Saturated activated carbon can be desorbed and reused, reducing maintenance costs.5. Application ScopeChemical Industry: Waste gases from the production of various organic chemicals, pharmaceuticals, and resin manufacturing processes.Automotive, Motorcycle, and Bicycle Industries: Surface coating waste gases from metal and plastic parts.Machinery, Shipbuilding, Home Appliances, Furniture, and Building Materials Industries: Surface coating waste gases from metal and plastic parts.Various waste gases from industries such as shoe manufacturing, printing, coating, electronics, enameled wire production, asphalt, rubber product manufacturing, and food processing.6. AdvantagesHigh Efficiency: Capable of efficiently converting harmful gases into harmless ones.Environmental Friendliness: No secondary pollution; activated carbon can be reused.Economic Benefits: Energy-saving and cost-effective, offering high overall value.RCO catalytic combustion equipment plays a vital role in the environmental protection field, effectively improving environmental quality by efficiently treating various organic waste gases. more>

Product Description: Product Name: Glass Code DiscProduct Material: Float glass, K9 glass, ultra-clear glass, etc.Standard Thickness: 0.7mm, 1.0mm, 1.1mm, 2.0mm, 3.0mmProcess Advantages:1. Pulse lines are uniform, vertical, and smooth, with no disconnections or breaks;2. High precision, no limit on pulse count, minimum line size can be as small as 0.006mm;3. Small tolerance can reach 0.2 microns;4. Excellent thermal stability, extremely high mechanical strength and pressure resistance;5. Good cleaning effect, reusable, long lifespan, wide range of applications;Precision: Tolerance ±0.0002mm (i.e., 0.2 microns), industry standard;Delivery Time: Standard sampling 30 days, delivery 40 days.Application: A digital encoder for measuring angular displacement. It offers strong resolution, high measurement accuracy, and reliable performance, making it a commonly used displacement sensor for measuring shaft rotation angle.A code disc (grating disc) is a circular plate with evenly spaced rectangular apertures. Since the photoelectric code disc is coaxial with the motor, when the motor rotates, the code disc (grating disc) rotates at the same speed. The detection device, composed of electronic components such as light-emitting diodes, detects and outputs several pulse signals. By calculating the number of pulses output by the photoelectric encoder per second, the current motor speed can be determined. more>

The side of the mining FQC5.0 pneumatic fan is equipped with this handle, eliminating the need to move it by gripping the edges.
$2100
Category: Hardware & Tools/Pipe Fittings/Tee Fittings
Company: 烟台乐森机械设备有限公司
Product Description: Due to fluctuations in raw material prices, the models and prices may vary. For specific quotations, please contact our sales staff. Thank you.The detailed design of the mining pneumatic fan really impresses me! The side handle is quite practical—no more struggling to move it by gripping the edges underground. Just lift and go, stable and effort-saving. Attention to detail means fewer hassles during work, significantly boosting efficiency! If you don’t believe it, you can buy one and try it yourself.Pneumatic fans are mainly used for localized exhaust ventilation in coal mines underground, and can also be applied in scenarios requiring localized ventilation such as metallurgical mines and tunnel engineering.There are two specifications of mining pneumatic fans: the FQ forced-type pneumatic fan and the FQC exhaust-type pneumatic fan. These two types operate on different working principles. Unlike electric counter-rotating fans, the forced-type pneumatic fan is more expensive, but its output is not at the same level.FQC Pneumatic Fan Working Parameters:Model: FQC No. 5.0Air Volume (m³/s): 3Air Pressure (Pa): 180Air Supply Pressure (MPa): 0.45Air Consumption (m³/s): 0.033Rotation Speed (r/min): 3000Diameter (mm): 315Weight (Kg): 25Length (mm): 280Preparation and Inspection Before Use:1. Before using the pneumatic fan, check whether all components are complete and whether the connections are correct and secure.2. Slowly open the air valve to observe whether the rotation direction of the impeller matches the direction indicated on the casing, and check whether the rotating parts move flexibly without noise, impact sounds, or abnormal noises. Once everything is normal, the fan can operate normally.3. If the air volume fluctuates significantly during operation, stop the fan immediately. Check for air leaks in the pipeline or manually rotate the impeller to detect any motor malfunctions, and address the issue accordingly.Industrial Ventilation: Suitable for localized ventilation needs in industrial scenarios such as metallurgy and mining.Tunnel Engineering: Can solve ventilation problems during tunnel construction, improving the working environment.
