The bag filter should have the characteristics of reasonable structure, high dust collection efficiency, low power consumption, convenient installation and maintenance, and simple operation.
Bag dust collectors should consider the characteristics of flammable and explosive coal powder when collecting raw coal materials.
The bag filter needs to operate continuously and respond to the temperature of the exhaust gas. It has a strong adaptability to the moisture content and dust characteristics. Too high, etc.) continuous operation, and can ensure dust collection efficiency.
The filter bag should be made of organic chemical (synthetic) fiber filter cloth and twill weaving method, which has wear resistance, heat resistance, anti-condensation, strong air permeability, small pressure loss, low absorption rate, high strength, light weight, and acid and alkali resistance. , Anti-corrosion and other characteristics, the service life of the filter bag should exceed 15000 hours.
The filter bag should be easy to install and fix, and supported by a flexible metal mesh bag cage. The bag cage should be made of heat-resistant, wear-resistant, and corrosion-resistant materials, and have sufficient strength and rigidity to ensure long-term operation without deformation, and its service life should not be less than three years. (Single bag filter bag quoted at the time of bidding)
The production of the bag cage should ensure the smoothness, and try to avoid abnormal conditions such as scratching, damage and wear of the filter bag caused by burrs, bad nodes and welding points.
The cloth bag dust collector shall adopt the structure of a separate chamber air box, and the top or side of each room shall be provided with a sealed door to facilitate the replacement of the filter bag.
The filter bag ash cleaning device uses a compressed air pulse injection system. The system should include an air storage tank, an oil-water separator, an air supply line, a pressure gauge, a stop valve, a pulse valve , a solenoid valve, a pneumatic lift valve, and a ash cleaning program controller. Wait. The buyer requires that the filter bag cleaning system has a strong spray effect, uniform pulse impact transmission, good dust cleaning effect, small secondary dust, and the spraying cycle can be adjusted according to the actual situation such as dust concentration and viscosity.
The filter bag dust removal system should be simple and reasonable in structure, well sealed, and reliable in operation. Its key components (such as solenoid valves) are selected from foreign companies or their domestic agents.
The bag dust collector housing should have sufficient strength and rigidity to ensure that it does not deform under various abnormal working conditions, and has good sealing performance and low air leakage rate.
The cloth bag dust collector shall adopt a suitable steel structure support or support type, and shall also be equipped with a bracket, ladder, platform, railing, lighting, etc. that meet the requirements of equipment inspection and maintenance. Relevant requirements for the height of its steel supports or bearings are to be formally determined when signing a contract with the successful bidder.
The bag dust collector and ash collecting bucket shall be determined by the seller according to the climatic characteristics and material characteristics of the project, whether to install electric heaters, vibrators, etc. to prevent paste bags and blockages.
The ash discharging device at the bottom of the ash collecting hopper and / or the air-locking valve for discharging material should have sufficient capacity to meet the requirements of excessive delivery in a short period of time. Bag dust collectors should be equipped with special electrical control equipment such as reliable dust cleaning program controllers, and can communicate with the process control system, interlock and control.
