Dust removal under high temperature conditions "black technology" Lifeldt bag dust collector design fully considered the special needs of the heat treatment industry. Its core advantages are reflected in three aspects: high temperature resistant filter material and intelligent ash cleaning system filter bag using PTFE coated filter material (temperature resistance 260℃, instantaneous up to 300℃) and glass fiber composite material, the surface is specially treated, with "oil, hydrophobic, anti-condensation" characteristics. To solve the problem of easy hardening after mixing oil mist and metal dust, the equipment is equipped with high pressure pulse back blowing + mechanical vibration dual cleaning mode, and real-time monitoring resistance value through the pressure difference sensor, automatic adjustment of cleaning frequency, extending the service life of the filter bag to more than 3 years. Safety and explosion-proof design considering the risk of explosion caused by quenching oil mist, the main body of the equipment is made of Q235 carbon steel, and the built-in explosion-proof pressure relief port. The air inlet is equipped with a cooling spray pretreatment device to ensure that the temperature of the flue gas before entering the dust collection system is below 180℃ to avoid the burning of the filter bag. Modular flexible deployment equipment supports single (5000-100000m³/h handling air volume) or multi-unit parallel combination, which can be flexibly configured according to workshop space and dust production volume. For example, the small and medium-sized quenching shop can use the LFT-C single machine, while the large forging line can achieve centralized dust removal through the LFT-A modular system.

Systemic solutions from high temperatures to emissions Heat treatment processes produce flue gas with complex components (iron oxide, mineral oil volatiles, CO/CO₂, etc.), and traditional dust removal equipment often faces the following challenges: The direct filtration of high temperature flue gas can easily lead to the burning of the filter bag and the mixing of oil mist and dust to form viscous particles, blocking the filter bag emission standards are increasingly stringent (GB 16297 requires Comprehensive improvement of environmental protection, economy and safety 1. Environmental compliance measured emission concentration ≤15mg/m³, far lower than the national standard requirements, to avoid the risk of environmental fines. A steel plant was awarded "green production demonstration Project" after application. 2. Energy efficiency and cost optimization Intelligent ash cleaning system saves 40% energy compared with traditional fixed frequency ash cleaning, and saves 80,000-120,000 yuan in electricity bills annually; Longer bag life reduces maintenance costs by 30%. 3. Safe production ensures that the PM10 concentration in the workshop is reduced from 2-5mg/m³ to 0.3mg/m³, reducing the occupational disease risk of workers; Explosion-proof design and real-time monitoring system eliminate fire hazards.

particulate matter ≤30mg/m³) Liffelter solves the above problems through the "pretreatment + hierarchical filtration + intelligent control" systematic solution: 1. The flue gas of the multistage pretreatment system is first removed by a cyclone (≥80μm), and then the temperature is lowered to the filter bag tolerance range by the cooling tower. This step not only protects the filter bag, but also significantly reduces the subsequent dust removal load. 2. Anti-viscosity filter bag technology PTFE coated filter material surface is smooth, oil mist particles are difficult to adhere. With regular backblowing ash cleaning, the air permeability of the filter bag can still maintain more than 90% of the initial value after three years of operation. 3. Intelligent emission monitoring and linkage control integrated online VOCs detector and particulate counter, real-time data and ash cleaning system, fan speed linkage. For example, when the emission concentration approaches a critical value, the system automatically increases the cleaning frequency to ensure stable compliance.
