PP washing tower is a new type of industrial waste gas treatment equipment. It is produced on the basis of the industrial waste gas purifier with floating packing layer. It is widely used in the pretreatment of industrial waste gas treatment and dust removal. The purification effect is very good. It is commonly used in the treatment of acid and alkali waste gas. Processing equipment. The PP washing tower produced by our company is different from the existing washing tower on the market. It is made of light polypropylene in plastic, that is, PP material. The washing towers produced by our company are mainly divided into two types: packed towers. And the swirling tower, while the packed tower is relatively widely used. When there is more dust in the exhaust gas, a swirling tower can be selected. The PP washing tower has the characteristics of simple structure, low energy consumption and high purification efficiency, and can effectively remove hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia gas (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3). Water-soluble gas such as hydrogen cyanide gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), and formalin (HCHO). The acid mist exhaust gas is introduced into the purification tower by the air duct, and passes through the packing layer. The exhaust gas and the sodium hydroxide absorption liquid are fully contacted by the gas-liquid two-phase to absorb the neutralization reaction, and the acid mist exhaust gas is purified, and then dehydrated and defogged by the defogging plate. The fan is discharged into the atmosphere. After the bottom of the tower is pressurized by the water pump, the absorption liquid is sprayed on the top of the tower, and then returned to the bottom of the tower for recycling. The purified acid mist exhaust gas meets national emission standards. The PP washing tower itself comprises a body, a filling layer, a defogging layer, a circulating sprinkling pipe, and a circulating water tank. The PP washing tower body comprises an exhaust gas inlet, an outlet, a window, a maintenance inlet and a structure for supporting and fixing inside the PP washing tower to ensure the corrosion resistance of the PP exhaust gas scrubbing tower itself increases its service life. PP washing tower principle and structure The PP washing tower is an advanced technology product of environmental protection technology. The function of the PP washing tower is to remove the impurities in the gas by solvent reaction, and it can be used in various industries that generate washing gas. The waste gas waste liquid enters the tower and is in full contact with the washing liquid in the tower, so that impurities can be removed to achieve the function of purifying the gas. It itself includes a body, a filling layer, a defogging layer, a circulating sprinkler pipe, and acirculating water tank. The PP washing tower body comprises an exhaust gas inlet, an outlet, a window, a maintenance inlet and a structure for supporting and fixing inside the PP washing tower to ensure the corrosion resistance of the PP exhaust gas scrubbing tower itself increases its service life. Features: PP washing tower with low noise, stable operation, simple and convenient operation; professionally used in the electroplating industry and the acid-base gas generated by five surface treatments for neutralization treatment, using excellent PP plate, the air volume can be randomly adjusted and used. Location application The device itself includes a body, a filling layer, a defogging layer, a circulating sprinkling pipe, and a circulating water tank. Washing tower body The washing tower body comprises an exhaust gas inlet, an outlet, a window, a maintenance inlet hole and a structure for supporting and fixing inside the washing tower to ensure the corrosion resistance of the device itself increases the service life thereof. Fill layer The ∮75 Raschig ring is used as a washing tower filler, and its material is PP. The ∮75 PP Raschig ring has the characteristics of large specific surface area, low pressure loss, and low material transfer height. Compared with its filling material, the ∮75 PP Raschig ring has higher processing efficiency and lower operating cost. Defogging layer ∮50 PP hollow ball is used as the defogger material for PP Circulating sprinkler pipe The pipeline material is PP. The main function is to send the circulating water to the sprinkler system. The nozzle used in the sprinkler system adopts a spiral type nozzle. The nozzle has the characteristics of not easy to block, large spray angle and uniform droplet distribution. The washing tower can exert a good treatment effect. • Circulating sink The circulating water tank is connected with the main body of the washing tower, the water tank has a circulating water volume of 2-3 minutes, the floating water level controller is arranged inside the water tank, and the washing water inlet overflow port and the discharging water port are reserved. Applicable to:electronics industry, semiconductor manufacturing, PCB manufacturing, LCD manufacturing, steel and metal industry, electroplating and metal surface treatment industry, pickling process, dye/pharmaceutical/chemical industry, deodorization/chlorine neutralization, combustion exhaust SOx /NOx is removed, other water soluble air pollution. PP washing tower performance characteristics: (1) Physical properties: The PP scrubber is particularly stable to water, and the water absorption rate in water for 14 h is only 0.01*. The molecular weight is between 8 and 150,000, and the formability is good. (2) Mechanical properties: PP washing tower has high crystallinity and regular structure, so it has excellent mechanical properties, and its strength, hardness and elasticity are higher than high density PE (HDPE). The outstanding feature is the flexural fatigue resistance (7×10^7) secondary opening and closing bending without damage marks, and the dry friction coefficient is similar to that of nylon. (3) Thermal properties: PP washing tower has good heat resistance, melting point is 164~170 °C, and the product can be sterilized at temperatures above 100 °C. It is not deformed at 150 °C without being subjected to external force. The embrittlement is -35 ° C, embrittlement occurs below -35 ° C, and the heat resistance is not as good as PE. (4) Chemical stability: PP washing tower has good chemical stability. Besides being attacked by concentrated sulfuric acid and concentrated nitric acid, it is stable to various other chemical reagents, but low molecular weight aliphatic hydrocarbons and aromatic hydrocarbons can PP softens and swells, and chemical stability increases with increasing crystallinity. Therefore, PP is suitable for the production of Russian-Chinese chemical pipes and fittings with good anti-corrosion effect. (5) Electrical properties: The PP washing tower has excellent high-frequency insulation performance. Since it hardly absorbs water, the insulation performance is not affected by humidity, has a high dielectric constant, and can be used to make heat as the temperature rises. Electrical insulation products, high breakdown voltage, suitable for electrical accessories. (6) Weather resistance: The PP washing tower is sensitive to ultraviolet rays, and zinc oxide thiopropionate dilaurin and carbon black-like milky white filler can be added to improve the aging resistance. Maintenance and maintenance The organization shall conduct inspection and maintenance within 30 days after commissioning for qualified use. Inspection and maintenance content: 1: Remove dust and dirt from the surface of the mechanism. 2: Sprinkler head, with or without blockage. 3: Clean the water tank with or without sedimentation and clean up the records to facilitate customization of the next cleaning time. 4: Observe whether there is heavy stain on the surface of the Raschig ring. If it needs to be taken out and placed in a large area of the sink, neutralize the stain with a neutralizing agent. 5: According to the exhaust odor or data to determine whether the activated carbon needs to be replaced, after use, the activated carbon can be exposed to the sun to regenerate. 6: Check the pump for abnormal noise, looseness and blockage.
