Waste gas equipment and treatment technology are commonly used in paper mills

Paper mill, paper mill common exhaust equipment and process introduction exhaust gas composition are mainly: benzene, toluene, xylene, acetone, ethyl acetate, cyclohexanone, alcohols, such as exhaust gas mainly for condensate gas, its composition containing H2S, CH3SH and CH3SCH3, CH3SSCH3 sulfur-containing compounds, still contain turpentine oil, methanol, water vapor, nitrogen, oxygen and other gases, corrosive, toxic, if not processing can be a certain effects on the workers and surrounding residents and environment. Nugget of botou city environmental protection equipment co., LTD. Is specialized in handling the paper mill waste gas, the paper mill waste management experience, will be in the system of waste gas into the waste gas treatment equipment, can put an end to its causing serious pollution of air, my company processing craft, for the paper mill waste gas after waste gas scrubber + uv light oxygen catalytic synthesis processing waste gas treatment equipment, translate into air pollution gases, again by 15 meters high chimney emissions into the atmosphere, effectively guarantee the air quality and health life.

Let's share the paper mill waste gas treatment equipment and paper mill waste gas treatment process.

1. Water spraying: make use of the characteristics of water soluble in odors and some substances in organic waste gas to make odors and organic waste gas components come into direct contact with water, so that granulator waste gas treatment equipment manufacturers can dissolve in water to achieve the purpose of removal. It is suitable for water - soluble, organic waste gas. The process is simple, the management is convenient, the equipment operation cost is low, but produces the secondary pollution, needs to deal with the washing liquid; Purification efficiency is low, should be used in combination with other technologies, the organic waste gas treatment effect is poor.

2. Photooxygen catalytic oxidation: special high energy and high ozone UV light beam is used to illuminate the exhaust gas to make the molecular chains of organic or inorganic polymer odor compounds react with ozone to generate low molecular compounds, such as CO2 and H2O, under the irradiation of high energy ultraviolet light beam. Low investment cost, wide application, high purification efficiency, simple operation, good deodorization effect, stable operation, small footprint, low operating cost, on demand, no secondary pollution. Good effect on organic waste gas treatment.

The characteristics of paper mill production process in the exhaust fumes, produce the stench, adhesion, high temperature, high humidity, this case if you want to fully processed waste gas can't meet the requirement of discharging standard, the paper mill waste gas treatment technology must be used to solve, so the first thing you need to solve the problem is that in higher than 80 degrees temperature under the condition of light catalysis oxygen equipment illuminant efficiency was only about 50% of 40 ℃, if be morohology was stuck to the uv lamp, they can't send out light, no light source the light oxidation equipment, no purification treatment effect. This process in light oxidation equipment before setting spray scrubber water for cooling and dedusting, The coarse filter is used as the pretreatment equipment to ensure that the dust in the exhaust gas introduced by the original auxiliary induced draft fan can be effectively intercepted and filtered when it enters the optical-oxygen exhaust gas treatment device.
