In the treatment of industrial waste gas, the Waste Gas Purification treatment method with low cost, low energy consumption and no secondary pollution should be selected first, and the waste heat of the waste gas should be fully utilized to realize the recycling of resources. Under normal circumstances, due to the particularity of their production activities, petrochemical enterprises often use methods such as condensation, absorption, and combustion to purify exhaust gas. However, the concentration of exhaust gas in printing and other industries is low, and methods such as adsorption and catalytic combustion are often used to purify exhaust gas. The following is a brief overview of these methods:
We are a manufacturer of Exhaust Gas Purification Device equipment, with quality assurance, factory direct sales, quality assurance, affordable prices, and large quantities. 1. Condensation recovery method The condensation method is to directly introduce the waste gas from industrial production into the condenser, and through the action and reaction of adsorption, absorption, analysis, separation and other links, recover valuable organic matter, recover the waste heat of the waste gas, purify the waste gas, and make the waste gas meet the emission standard. When the concentration of organic waste gas is high, the temperature is low, and the air volume is small, the condensation method can be used for purification treatment, which is generally used in pharmaceutical and petrochemical enterprises. Usually, one or more stages of other organic waste gas purification devices are installed behind the condensation recovery device to achieve standard discharge. 2. Absorption method The physical absorption method is often used in industrial production, that is, the exhaust gas is introduced into the absorption liquid for absorption and purification, and after the absorption liquid is saturated, it is heated, decomposed, condensed, etc., and the waste heat is recovered. In the case of low concentration, low temperature, and large air volume, the stepping absorption method can be used, but it needs to be equipped with a heating analysis recovery device, which requires a large investment. It involves oil curtains and water curtains commonly used by paint coating companies to absorb paint mist, that is, the common organic waste gas absorption method.
HVAC Air Purification Devices, Air Sterilizer, Industrial & Kitchen Air Purifier and other products cover the world, the source manufacturers sell directly, there is no intermediate profit, factory direct sales, welcome customers to consult and patronize. 3. Direct combustion method The direct combustion method is to use auxiliary materials such as gas to ignite the exhaust gas, so as to promote the conversion of harmful substances into harmless substances under high temperature combustion. This method has small investment and simple operation. High technical requirements.
