The acid mist spray tower uses the packed tower to purify the exhaust gas, which is suitable for the treatment of continuous and intermittent exhaust gas; the process is simple, the management, operation and maintenance are quite convenient and concise, and will not have any impact on the production of the workshop; the scope of application is wide. At the same time purify a variety of pollutants; low pressure drop, high flexibility, and good defogging performance; tower body can be made of FRP / PP / PVC and other materials according to the actual situation; filler with high efficiency, low resistance of Bauer The ring can completely remove odors, harmful substances and the like in the gas.
   The working principle of the acid mist spray tower: the acid gas enters the purification tower tangentially from the inlet below the tower body. Under the power of the ventilator, it quickly fills the space of the intake section and then uniformly rises to the first through the equalization section. Grade packing absorption section. On the surface of the filler, the acidic substance in the gas phase chemically reacts with the alkaline substance in the liquid phase. The reaction product oil (mostly soluble salts) flows into the lower sump with the absorbing liquid. The acid gas that is not completely absorbed continues to rise into the first stage spray section. In the spray section, the absorbing liquid is ejected from the uniformly distributed nozzle at a high speed, and numerous fine droplets are formed to sufficiently mix and contact with the gas to continue the chemical reaction. The acid gas then rises to the second stage packing section and the spray section for an absorption process similar to that of the first stage. The second stage is different from the first stage nozzle density, the spray pressure is different, and the range of absorbed acid gas concentration is also different. The process of contact between the spray section and the packing section is also a process of material heat and mass transfer. The process is adequate and stable by controlling the empty tower flow rate and the stagnation time. For some chemically inactive acid gases, it is necessary to add a certain amount of surfactant to the absorption liquid. The uppermost part of the tower body is the defogging section, and the absorbing liquid mist trapped in the gas is removed here, and the treated clean air is put into the atmosphere from the upper exhaust pipe of the purification tower.

Laminated Veneer Lumber (LVL)
Laminated Veneer Lumber (LVL) is another type of Plywood. It is made of multiple layers of thin wood (along the same direction of wood fiber), assembled with adhesives through hot-pressing.
Currently, the core veneers are mainly Poplar, Eucalyptus, Eucalyptus and Poplar mixed, Paulownia and Poplar mixed etc.
