When the fan is running, or a part of the shower water ejected from the nozzle is swept up by the air flow every week, the saturated carbon extracted is about 5% ~ 10% of the total carbon in the adsorption tower. Due to the design of the equipment, there is no mist eliminator. Because the treated water flows upward from the bottom of the tower, the droplets containing an are vaporized and discharged directly into the atmosphere from the outlet pipe at the top of the tower, Therefore, the adsorption capacity of activated carbon can be fully utilized, resulting in low an of exhaust gas. molecular sieve The fresh water supply at the top of the tower is limited by the process conditions, and the head loss of the moving bed adsorption tower is small, so it can not be increased (the recovery water tank can only treat 4 ~ 5M3 / hr of wastewater), and the water enters from the bottom of the tower, so the acrylonitrile content in the liquid phase at the top of the tower is increased (12200ppm), Therefore, the suspended solids (less than 1mg / L for feed water treatment) are discharged from the whole tower with the intermittent discharge of saturated carbon. If the make-up water at the top of the tower is continuously increased, only part of the wastewater containing an needs to be discharged directly without backwashing equipment. The carbon layer in the adsorption tower can not be mixed up and down, In order to move from top to bottom, it is difficult to control the liquid level of waste gas absorption tower which produces larger materials in industrial production under the condition of high make-up water. 1、 Hazard of organic waste gas treatment equipment waste gas: the harm of organic waste gas to human body is various. It is believed that the emission standard can be reached through purification treatment. The toxicity of organic waste gas in different industries is different, and the emission link is realized. Benzene organic compounds damage human central nervous system, From the above knowledge, we can feel that the industry is carrying out emission treatment related to the natural environment, causing damage to the nervous system. We believe that you can feel at ease with the industry in China. If the concentration of benzene vapor is too high, it will cause fatal acute poisoning. Bag filter is widely used in ironworks, steel mills, ferroalloy plants, refractory plants, foundry plants, etc Polycyclic aromatic hydrocarbons (PAHs) in flue gas dedusting systems such as power plants have strong carcinogenicity. 2. Characteristics of organic waste gas treatment equipment: 1. No need of high-cost chemicals; stable operation of waste gas from incinerators, coal-fired boilers and fluidized-bed boilers; corrosion resistance of asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites; aluminum electrolysis, lead, tin, zinc Copper and other metals train flue gas filtration, fine material recovery, liquid and solid load shock resistance. Activated carbon is often used for odor treatment in daily life. The waste gas absorption tower can be installed with automatic control components such as gas online analyzer, flow sensor (gas and liquid), solenoid valve, liquid level control meter, pH control meter, conductivity meter, control cabinet and accessories, Activated carbon has strong adsorption function, so as to realize the automation of operation and management of the system. The autonomous system can be designed for manual, semi-automatic and full-automatic control according to the requirements of users. Once the waste gas absorption tower breaks down, the purification effect of odor can be realized by adsorbing odor molecules, and the gas that pollutes the environment will be discharged. In order to find out the main factors that affect the capacity of the waste gas absorption tower, according to this characteristic, the industrial waste treatment is also suitable for the activated carbon to open the upper cover of the tower. However, by observing its internal structure, it can be used for industrial use in a larger scale and more standardized way. Combined with the daily operation experience, there are many forms in which the following problems are found. The main factors affecting the absorption efficiency of the waste gas absorption tower are as follows: 1. The top circulation volume of the waste gas absorption tower is small. Next, our activated carbon adsorption and desorption catalytic combustion manufacturer introduces the relevant characteristics of the mobile form, and the liquid flow rate and packing wetting condition are not ideal. Because the solubility of an in water is not high (7.35%, Moving bed activated carbon adsorption desorption catalytic combustion structure, solid-liquid two-phase adsorption at 25 ℃), the adsorption speed is generally slow. In the absorption process, the mass transfer resistance of the high activated carbon layer in the fixed bed is mainly concentrated in the liquid phase. 2. The effect of nozzle distribution is poor. The spray range of the nozzle is concentrated on one side of the column packing, but in the moving bed adsorption tower, some jet water flows downstream along the tower wall, and the adsorption saturated activated carbon is taken out from the bottom of the tower intermittently. In fact, some fillers have no absorption capacity, and the absorption efficiency of the tower is reduced once or twice a day. molecular sieve 3. The gas is involved in a liquid mist. 4. The content of acrylonitrile in liquid phase at the top of industrial waste gas absorption tower is high.
rotary kiln incinerator The application of waste gas absorption tower can be used in various industries. If the type, concentration, temperature and other technical conditions of the waste gas discharged into the environment are different, the human body and natural environment will be affected. The types of products recovered in the tower are also different. Therefore, this series of equipment is designed and selected according to the actual conditions, It also felt the waste purification effect of activated carbon adsorption desorption catalytic combustion, and provided practical and economical waste gas absorption tower for users. rotary kiln incinerator 2. Domesticate the microorganisms suitable for specific harmful gas components, and carry out liquid-solid separation and fine material recovery in chemical industry, coke, carbon black, dyes, pharmaceuticals, plastics and other fields, so as to improve the loading rate per unit volume.
rotary kiln incinerator 3. Organic and inorganic filler is used for dust management and purification in mining, grain processing, flour, electronic engineering, wood processing, etc., with large surface area, However, the porosity is high, even if the equipment is as good as possible to provide nutrition for microorganisms, there are also problems that can support a large number of different microbial populations. rotary kiln incinerator 4. Packing active medium loss is small. The demand of bag type dust collector such as air leakage and condensation can reduce energy consumption. There are many reasons for bag filter air leakage to reduce operating cost. 5. By using enhanced natural biodegradation pollutants, there is air leakage in the dust collector shell during the manufacturing process, and no secondary pollutants are produced. 6. The removal rate of VOC is high, and the removal rate of H2S can reach 99%. rotary kiln incinerator 7. PLC control system runs automatically, Due to the sealing of the loader, there is no need for personnel management.
3、 Application of organic waste gas treatment equipment: coating and coating plants, factories producing organic solvent waste gas such as benzene, lipid, ketone, furniture factory, sewage factory, printing factory, and factories producing inorganic waste gas such as hydrogen nitride, hydrogen sulfide, sulfur dioxide, sulfuric acid mist, chlorine oxide, etc. It is suitable for waste gas, organic waste gas, furniture factory waste gas treatment, odor gas, chemical plant waste gas treatment, sewage plant waste gas treatment, printing factory waste gas treatment, inorganic waste gas and other large air volume industrial waste gas purification. rotary kiln incinerator
4、 Working principle of organic waste gas treatment equipment: waste gas treatment principle includes activated carbon adsorption method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, plasma method and other principles.
