First, the working principle
The working principle of the exhaust gas absorption equipment is to separate the pollutants in the gas and convert them into harmless substances to achieve the purpose of purifying the gas. It belongs to the differential contact counterflow type, and the packing in the tower body is the basic component of gas-liquid two-phase contact. After the gas outside the tower body enters the tower body, the gas enters the packing layer. There is a spray liquid from the top and a spray liquid from the front on the packing layer, and a liquid film is formed on the packing. When the gas flows through the gap of the packing, Contact with the packing liquid film and carry out absorption or neutralization reaction, the packing layer can provide a sufficiently large surface area without causing excessive resistance to the gas flow, and the absorbed or neutralized gas is discharged out of the tower through the air outlet.
The absorbent is the main medium for treating exhaust gas. Its properties and concentrations are selected according to the properties of different exhaust gases. The consumption of the unit gas is determined by calculating the ratio of the molar flow rate of the absorbent to the inert gas. Exhaust gas is sucked in by the fan from the air duct and passes through the packing layer from bottom to top; the circulating absorbent is sprayed uniformly into the packing layer from the top of the tower through the liquid distributor, flowing down the surface of the packing layer and entering the circulating water tank. Due to the continuous contact between the updraft and downdraft absorbent in the packing, the concentration of the fluid in the updraft is getting lower and lower, and the discharge requirements are reached when the tower top is reached. The liquid on the liquid film flows into the liquid storage tank under the action of gravity, and is circulated by the circulation pump.
1. PP waste gas absorption equipment has a wide range of applications: organic waste gas, sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid and other exhaust gases emitted during the production process of industrial sectors such as chemical industry, light industry, printing and dyeing, medicine, steel, machinery, electronics, instrumentation, electroplating And sulfur oxides (SOx), nitrogen oxides (NOx), carbon oxides (CO, CO2), cyanide (HCN) and other acid gases, using industrial waste gas absorption equipment, can achieve satisfactory results.
2. Low resistance of PP exhaust gas absorption equipment: On the basis of ensuring sufficient gas-liquid contact area, industrial exhaust gas absorption towers use aerodynamic characteristics of filler types and structural forms, so that the resistance of the equipment does not exceed 40 mm water column at the rated air volume. One kind of packing absorption tower with low resistance. This is advantageous for use with corrosion-resistant low-pressure fans.
3. The small footprint of PP exhaust gas absorption equipment: industrial waste gas absorption treatment tower adopts PP and other materials. The tower body, circulating water tank, circulation pump, and absorption liquid pipeline system are combined into a complete set of industrial waste gas treatment equipment. Installation and operation management, with a small footprint, can be adapted to new construction or technical renovation projects.
