Reasons for the stable development of waste gas treatment equipment

When it comes to industrial waste gas, I think the first thing that many friends think of is waste gas emissions, but there are also many industrial waste gases that are not commonly seen by everyone, so waste gas treatment equipment has attracted many people's attention, then such mechanical equipment is complete. What is it? Today, I will understand the common sense issues for you.

The digestion and absorption method uses low-volatility or non-evaporative organic solutions to digest and absorb VOCs, and then use the different physical properties of VOCs and adsorbents to extract them. 

The gas containing VOCs enters the tower from the bottom of the flue gas desulfurization tower, and countercurrently collides with the adsorbent from the top of the tower during the whole process of raising, and the purified gas is discharged from the top of the tower. After digesting and absorbing the VOCs, the adsorbent enters the top of the stripping column according to the heat exchanger, and is analyzed under the condition that the temperature is higher than the digestion and absorption temperature or the pressure is lower than the digestion and absorption pressure. The decomposed adsorbent is cooled by the organic solution cooling tower and returned to the flue gas desulfurization tower. Not to mention that the analyzed VOCs gas leaves the stripper as purer VOCs gas after cooling tower and gas-liquid separator, and is developed and utilized. This technology is suitable for gas purification treatment with high VOCs concentration value and low temperature. In other cases, matching production process adjustments must be made.

When using a solid component of a porous material to treat a liquid mixed component, a component or components in the liquid can be attracted to the surface and concentrated thereon, a problem called adsorption. In the adsorption treatment of industrial waste gas, the other half of the adsorption is the gaseous environmental pollution components, and the gas-solid two-phase flow adsorption. The adsorbed gas component is called the adsorbate, and the solid component of the porous material is called the adsorbent.

After the adsorbate is adsorbed on the solid surface, a part of the adsorbed adsorbate can be resolved from the surface of the adsorbent, which is now attached. When the adsorption is carried out for a period of time, due to the concentration of adsorbate on the surface, the adsorption capacity is significantly reduced and the adsorption purification treatment is required. At this time, the exhaust gas treatment equipment must take certain precautions to make the adsorbent adsorb Adsorbate desorption to synergistic adsorption capacity, this whole process is called adsorbent remodeling. Therefore, in the actual adsorption construction project, it is exactly the whole process of adsorption-remodeling-adsorption cycle to ensure the removal of the damaged components in the industrial waste gas and the recovery of chlorogenic acid in the industrial waste gas.

Exhaust gas treatment manufacturers say that the ignition method is very effective for treating Voc with a high concentration value and compounds with rancid smell. Vapors can be expelled into the air. However, when dealing with sodium hypochlorite solution and sulfur-containing organic compounds, the ignition is converted into HCl or SO2 in the components, and the gas after ignition must be further processed.

The above are some detailed explanations and opinions on relevant waste gas treatment equipment. If you feel that there are different opinions on such mechanical equipment, you are welcome to leave a message on the message board. We will analyze the relevant experience and basic knowledge together.
