Zeolite rotor concentration + RTO regenerative thermal incineration combination process is the current exhaust gas treatment in the treatment of low concentration (less than 500mg/m3), large air volume of the mainstream technology. Due to the low concentration of waste gas with RTO exhaust gas treatment process direct combustion needs to be supplemented with natural gas and other large amounts of fuel, the operating cost is very high economic uneconomical. Therefore, it is necessary to concentrate the low-concentration exhaust gas into a high-concentration exhaust gas and then combustion. This not only saves energy but also reduces the size of the equipment, such as 50,000 air volume of exhaust gas requires a lot of equipment, but through the concentration of exhaust air volume will become very small, generally based on the concentration ratio of zeolite to determine the concentration of the air volume. For the current domestic zeolite, 50,000 air volume of large air volume, low concentration of exhaust gas by adsorption after desorption out of only 3,000 air volume of RTO equipment can be dealt with, which greatly saves the cost and operating costs.
Zeolite rotor concentration + RTO regenerative thermal incineration process flow
Zeolite rotor concentration device + RTO regenerative thermal incinerator consists of five parts:
I. Pre-treatment system
First of all, through the initial, medium and high three-stage filtration method, to remove fine particles in the waste gas, so that the organic waste gas to meet the cleanliness requirements of the zeolite rotor adsorption; and then through the method of temperature and humidity reduction, so that the organic waste gas to meet the temperature and humidity requirements of the zeolite rotor adsorption;
Second, zeolite rotor adsorption system
The zeolite can capture the molecules of VOCs with very low concentration, through the role of the fan, the pre-treated organic waste gas will pass through the adsorption area of the zeolite rotor, the organic molecules will be captured by the unique adsorption holes of the zeolite rotor, and the adsorbed gases that meet the standard will be directly discharged into the chimney;
Third, desorption system
After a period of adsorption, zeolite runner adsorption area will be adsorption saturation, at this time, with a small strand of heat (200 ~ 230 ℃) blowing zeolite runner desorption area, the organic matter from the zeolite desorption out of the incinerator through the fan into the zeolite regeneration, so the cycle;
Four, combustion system
The VOCs gas desorbed from the zeolite molecular sieve is sent to the combustion system for oxidative combustion through the fan to completely oxidise the organic waste gas into water and carbon dioxide.
V. Zeolite runner cooling system
Due to the zeolite after hot air blowing desorption, the temperature becomes high so that it can not adsorb organic matter, at this time the need for cooling zeolite cooling, so that it falls to room temperature, to ensure its adsorption efficiency.
Working Principle
Organic waste gas after pretreatment, into the rotor system, the rotor has been rotating. In the adsorption area, VOCs are adsorbed and intercepted by the porous zeolite adsorbent, and are discharged according to the standard. The rotor rotates to the desorption area, hot air (about 180℃ ~ 200℃c) is introduced to carry out high-temperature blowing desorption, and the desorbed high concentration and small air volume concentrated exhaust gas enters the RTO combustion treatment, releasing a large amount of heat and reuse the system.
Process flow
①Pre-treatment: The organic waste gas with large air volume and low concentration (<800mg/m3) generated in the workshop is piped into the dry filtration and other supporting pre-treatment equipment to remove most of the particles.
② Adsorption and concentration: VOCs gas after pretreatment, through the zeolite loading wheel adsorption area is adsorbed, high efficiency treatment and emission, VOCs are adsorbed and concentrated on the surface of the zeolite.
③High temperature desorption: the rotor will rotate to the desorption area, using the RTO mixer to provide 180~200℃ small air volume hot gas flow to carry out the reverse blowing desorption, the rotor gets desorption regeneration. ④RTO: The high concentration and small air volume of concentrated waste gas from desorption is sent to RTO for high temperature (>760℃) combustion and decomposition into CO2 and H2O, and the exhaust gas is discharged to the standard after heat storage. The heat recovery efficiency is high, greatly saving energy.
