Introduction to Exhaust Gas Absorption Tower
The application of exhaust absorption towers not only makes outstanding contributions to environmental protection, but also saves a lot of energy for enterprises and creates higher value.
The filling spray tower is mainly made of PP and PVC materials, and the filling material is made of PP material Ball ring or hollow sphere. According to the principle that the gas absorption process occurs at the gas-liquid interface, the transfer rate is proportional to the interface area. The filling material is used to increase the contact area between the two phases, so that the two phases are fully dispersed and achieve the purpose of purifying exhaust gas.
The tail gas absorption tower has the advantages of high purification efficiency, good corrosion resistance, light weight, high specific strength, small footprint, and large exhaust gas treatment capacity.
Structural characteristics and application scope of tail gas absorption tower:
The tail gas absorption tower equipment is made of polypropylene plastic and widely used in the absorption and purification treatment of tail gas and exhaust gas in the production processes of chemical, pharmaceutical, petroleum and other industries, achieving standard emissions.
Usage conditions and installation requirements for tail gas absorption tower:
The use of tail gas absorption tower equipment should comply with the material usage conditions, with a working temperature of -10 ℃ to 80 ℃. The installation should tighten the equipment foot bolts and install windproof steel ropes if necessary.
Working principle of exhaust gas absorption tower
The exhaust gas first enters the falling film recovery device through the exhaust pipe for cooling and falling film absorption to produce acid. The dilute acid liquid recovered by the falling film recovery device enters the storage tank through the exhaust pipe for recovery. The unabsorbed exhaust gas enters the first absorption tower, and the dilute acid liquid recovered by the first absorption tower enters the storage tank of this tower. The unabsorbed exhaust gas enters the storage tank of the second absorption tower, and the unabsorbed dilute acid liquid enters the storage tank of this tower. The small amount of unabsorbed exhaust gas enters the vacuum pump. The liquid recovered by the vacuum pump enters the main storage tank, and the standard exhaust gas absorbed by the vacuum pump is discharged through the exhaust pipe.
In the process of acid production, the low concentration dilute acid solution generated participates in the acid circulation reaction. The dilute acid solution produced in the subsequent process is used to supplement the reduced circulating liquid in the previous process. After the concentration meets the process requirements, it is stored centrally. This process completes the acid tail gas recovery process. This series of equipment can adopt automatic control to achieve unmanned management mode.

1. Adsorption:
Organic waste gas is filtered to remove solid particulate matter and enters the adsorption tank from top to bottom. The organic matter is captured, adsorbed, and concentrated by activated carbon, and the purified air is discharged from the lower part of the tank through the main fan
Entering the atmosphere.
2. Condensed water purification:
To ensure the cleanliness of the condensed water and avoid the discharge of organic solvents into the water, compressed air is introduced into the separated water in the separator to fully release the organic solvents in the water. The air containing organic matter expelled by compressed air is returned to the exhaust gas system and re adsorbed. The purified condensed water is discharged into the sewer.
3. Continuous adsorption measures:
In a continuous production factory, the adsorption system also needs to work continuously accordingly. In the design of the exhaust gas purification system, the dual tank series can be selected for alternating continuous use of adsorption and regeneration.
Structure and characteristics of exhaust gas absorption tower
The exhaust gas recovery device consists of a falling film recovery device, a first stage absorption tower, a second stage absorption tower, a vacuum pump, an exhaust pipe, and control instruments.
The structural design types of PP and PVC filling spray towers are divided into vertical and horizontal. The working principle of the vertical structure is gas-liquid two-phase vertical reverse contact, while the working principle of the horizontal structure is gas-liquid two-phase cross flow contact. The exhaust gas is absorbed and neutralized through the packing layer and liquid phase contact, thereby achieving purification effect. The packing layer in a single tower can be divided into single or double layers.
This series of equipment can be equipped with automatic control components according to application requirements, such as gas online analyzers, flow sensors (gas, liquid), solenoid valves, liquid level control meters, pH control meters, conductivity meters, control cabinets and accessories, etc., to achieve the automation of the operation and management of this system. The self-control system can be designed for manual, semi-automatic, and fully automatic control according to user requirements.
Exhaust gas absorption tower, exhaust gas purification tower, spray tower, packed towerScope of Application
1. Used in the textile and printing and dyeing industries. Polyacrylamide is used as a sizing and finishing agent for fabric treatment, as well as a protective layer that can generate softness, wrinkle resistance, and mold resistance. By utilizing its strong hygroscopicity, it can reduce the breakage rate of fine yarn during spinning. Polyacrylamide as a post-treatment agent can prevent static electricity and flame retardancy of fabrics. When used as a printing and dyeing additive, polyacrylamide can enhance the adhesion and brightness of the product, and can also serve as a non silicone polymer stabilizer for bleaching.
2. Mainly used as a flocculant: for wastewater with suspended particles that are coarse, high concentration, positively charged, and have a neutral or alkaline pH value, the anionic polyacrylamide molecular chain contains a certain amount of polar groups that can adsorb suspended solid particles in water, causing bridging between particles to form large flocs. Therefore, it accelerates the settling of particles in the suspension, significantly improves the clarification of the solution, and promotes filtration and other effects. This product is widely used for the treatment of chemical industry wastewater and waste liquid, as well as municipal sewage treatment. Water treatment in industries such as tap water, purification of high turbidity water, sedimentation, coal washing, mineral processing, metallurgy, steel industry, zinc and aluminum processing industry, and electronics industry.
3. Widely used in the petroleum industry, oil extraction, drilling mud, waste mud treatment, prevention of water breakthrough, reduction of friction, improvement of oil recovery rate, and tertiary oil recovery.
4. Used in the paper industry to improve the retention rate of fillers, pigments, etc. To reduce the loss of raw materials and environmental pollution; The second is to improve the strength of the paper (including dry strength and wet strength). In addition, using PAM can also enhance the paper's tear resistance and porosity to improve visual and printing performance. It is also used in food and tea packaging paper.
5. Other industries, such as the food industry, are used for sugarcane juice clarification and syrup phosphate float extraction in the production of sugarcane sugar and beet sugar. Enzyme based fermentation broth is used in the coagulation and clarification industry, as well as in the recovery, stable quality, and good performance of feed protein. The recovered protein powder has no adverse effects on the survival rate, weight gain, and egg production of chickens. It is also used in the synthesis of resin coatings, water blocking materials for civil engineering grouting, building materials industry, cement quality improvement, construction industry adhesives, joint filling and repair and water blocking agents, soil improvement, electroplating industry, printing and dyeing industry, etc.
The tail gas absorption tower has the advantages of low resistance, low energy consumption, low noise, and high treatment efficiency, and can treat various types of dust and exhaust gases.
The exhaust gas absorption tower has a high degree of customization, and the cyclone spray tower can be customized according to the actual situation of the enterprise, including the required air volume and power, pipeline direction, gas collection hood and other configurations.
