Oil fume treatment and absorption equipment in Tianjin Plastic Granulation Plant
Recycled plastic is generally made of waste plastic into granules, which is what we often say is plastic granulation. We recently installed a set of exhaust gas treatment equipment for a plastic pellet factory. Recycled plastics refer to plastic raw materials obtained after waste plastics processed by physical or chemical methods such as pretreatment, melting and granulation, and modification, and are the reuse of plastics. Waste plastic granulation uses heating and extrusion processes. During the production process, a certain amount of plastic waste gas is generated. The main component of plastic waste gas is volatile organic waste gas VOCS, which directly harms the human body and the environment. Exhaust gas emissions from the plastics industry are large and the composition is complex. The malodorous components have particularly serious pollution to the factory area and the surrounding environment. The activated carbon adsorption exhaust gas treatment process is used to treat foam plastic exhaust gas. We produce industrial exhaust ...

Spray tower manufacturer Senran exhaust gas treatment equipment
The filling layer in the spray tower of the spray tower manufacturer is used as a mass transfer device for the gas-liquid two-phase contact member. A packing support plate is installed at the bottom of the packing tower, and the packing is placed on the supporting plate in a random manner. A packing pressure plate is installed above the packing to prevent it from being blown by the updraft. The spray liquid from the spray tower sprays from the top of the tower to the filler through the liquid distributor, and flows down along the surface of the filler. The gas is sent in from the bottom of the tower, and after being distributed by the gas distribution device, it passes through the gap of the packing layer in a countercurrent with the liquid. When the liquid flows downward along the packing layer, a wall flow phenomenon sometimes occurs. The wall flow effect causes the gas and liquid phases to be unevenly distributed in the packing layer, thereby reducing the mass transfer efficiency. Therefore, the filling layer in the spray tower is divided into two sections, and a redistribution device is set in the middle.
