Classification of waste gas treatment equipment:
[absorption equipment]
The absorption of VOCs was carried out by the method of low volatile or non-volatile solvent, and then the differences between VOCs and absorbent were separated.
VOCs containing gas from the bottom of the absorption tower into the tower, in the rising process and from the top absorbent countercurrent contact the purified gas discharged from the tower. Absorption of VOCs absorber through the heat exchanger after entering the stripper top, the temperature is higher than the absorption temperature or pressure is lower than the absorption desorption pressure conditions. After desorption, the absorbent is returned to the absorption tower after the condensation of the condenser. VOCs gas desorbed through the condenser, a gas-liquid separator with pure VOCs gas leaving the stripper, be recycled. The process is suitable for the purification of gas with high VOCs concentration and low temperature, and other processes need to be adjusted accordingly.
[adsorption equipment]
In the use of porous solid material processing fluid mixture, fluid in one component or some components may be absorbed and concentrated on the surface, this phenomenon is known as adsorption. When the exhaust gas is treated by adsorption, the adsorbed object is gaseous pollutant. The adsorbed gas component is called the adsorbate, and the porous solid is called the adsorbent.
After the adsorption of the adsorbate on the solid surface, the adsorbed adsorbate can be separated from the surface of the adsorbent. When a period of time after adsorption, due to surface adsorbate concentration, the adsorption capacity decreased significantly while the adsorption purification requirements, the need to adopt some measures to make the adsorbate has adsorption desorption, the adsorption capacity of CO, a process known as adsorbent regeneration. Therefore, in the actual adsorption engineering, it is the use of adsorption and regeneration of the cycle of repeated adsorption to achieve the removal of pollutants in the exhaust gas and recovery of useful components in the exhaust gas.
Organic waste gas combustion and catalytic purification equipment
Combustion method is very effective for treating high concentration Voc and odorous compounds, the principle is to use excessive air to make these impurities burning, most of the carbon dioxide and water vapor, can be discharged into the atmosphere. But when the treatment of chlorinated organic compounds and sulfur, combustion HCl or SO2 production, need further processing of combustion gas.
Low temperature plasma treatment equipment for industrial organic waste gas
The plasma is an ionized gas, the English name is plasma, it was named by the American science Muir, in 1927 in the study of low pressure mercury vapor discharge phenomenon. The plasma is composed of a large number of atoms, neutral atoms, excited atoms, photons and free radicals, but the number of electrons and positive ions must be electrically neutral. Many aspects of the plasma, which are electrically conductive and affected by electromagnetic fields, are different from those of solids, liquids and gases, so it is called the fourth state of matter. According to the state, temperature and ion density, the plasma can be divided into high temperature plasma and low temperature plasma. The high temperature plasma ionization degree of various particle temperature close to 1, almost the same system in thermodynamic equilibrium, it is mainly used in the study of controlled thermonuclear reaction. However, the low temperature plasma is a non-equilibrium state. The electron temperature (Te) = ion temperature (Ti), more than 104K, and the ion and neutral particle temperature can be as low as 300 ~ 500K. The general gas discharge electron belongs to the low temperature plasma.
As of 2013, the study on the mechanism of low temperature plasma is considered to be the result of inelastic collision of particles. Low temperature plasma rich in electrons and ions, free radicals and excited molecules, including high-energy electrons and gas molecules (atoms) collision, which converts energy into ground state molecules (atoms) can occur, excitation, dissociation and ionization and a series of straw in the activated state. On the one hand to open the gas molecular bond, to generate some single molecules and solid particles; the other one of.OH, H2O2. and other free radicals with strong oxidation of O3 in high-energy electron plays a decisive role in this process, the thermal motion of ions only side effects. At atmospheric pressure, the temperature of the electron in the highly nonequilibrium plasma generated by the gas discharge is much higher than that of the gas temperature (about 100 DEG C). The chemical reaction of various types in non equilibrium plasma, mainly depends on the electron mean energy, electron density, gas temperature, harmful gas concentration and gas composition is more than. The need for some large activation energy of the reaction such as the removal of refractory pollutants in the atmosphere can also be provided for low concentration, high velocity, large volume containing volatile organic pollutants and sulfur pollutant treatment.
Methods plasma generated common is gas discharge, the gas discharge is through some kind of mechanism to make an electron out of gas ionization of atoms or molecules in the gas medium formed called ionized gas, if gas ionization produced by the electric field and the formation of conduction current, this phenomenon is called gas discharge. According to the mechanism of the discharge, the properties of the gas pressure J source and the geometry of the electrode, the gas discharge plasma can be divided into the following forms: glow discharge
