The temperature of forging is generally higher than 400 ℃. In order to prolong the life of the mold, a mold release agent must be used to protect the mold from corrosion. The hot forging release agent usually consists of 3 parts: the matrix that mainly plays a lubricating role, the carrier solvent and the additives that improve the comprehensive performance of the lubricant, such as extreme pressure agents, tackifiers and antioxidants. Graphite, molybdenum disulfide and compound stearate are typical solid lubricant bases. Because graphite emulsion has good lubricity, high temperature stability and adhesion characteristics at high temperature, it is widely used in the field of hot forming. Now hot die forging is released. The agent generally uses water-based graphite milk.

The flue gas produced by the lubricant is complex in composition and coexists in solid, liquid and gaseous phases. It contains hydrocarbon decomposition products such as polycyclic aromatic hydrocarbons, graphite, coke, and harmful gases such as CO and NO2. Pungent smell. The particle size of this kind of smoke is mostly less than 2.5μm, which is easily inhaled by workshop workers, endangering their health, and also causing poor visibility in the workshop, slippery floors, and potential safety and fire hazards. Therefore, appropriate treatment techniques must be adopted. Capture and purify the exhaust gas of forging release agent.

At present, the available purification processes on the market include wet dust collectors, bag filter dust collectors, filter cartridge dust collectors, and industrial electrostatic fume purifiers.

For the filter cartridge and bag filter, one is that it is not suitable for handling high-temperature flue gas, and the other is that due to the relatively high viscosity of hot forging flue gas, the filter bag will soon be blocked, resulting in a sharp drop in efficiency; for wet dust collectors , although it can handle high temperature flue gas, but the purification efficiency is low, especially for graphite dust with extremely small particle size, the treatment effect is very poor.

Many industrial electrostatic oil fume purifiers on the market are not suitable for this kind of exhaust gas, but the industrial electrostatic oil fume purifier developed and designed by our company has a different core filter module design and structure from other products on the market. Our three-stage sawtooth discharge, It can efficiently treat gaseous pollutants in the mixed state of water vapor, oil fume, exhaust gas and dust. At the same time, combined with the design of fire resistance, cooling, mechanical pre-filtration, etc., it can fully cope with the waste gas treatment conditions of forging release agents.
