The present invention relates to technical field of waste gas treatment, more particularly to the adsorption/desorption purifier of organic exhaust gas a kind of.
Background technology
The industries such as traditional external coating easy to produce the organic exhaust gas of Wind Volume, low concentration, as environmental protection examination is more next It is stringenter, these Wind Volumes, low concentration VOCs treatment become a great problem.
Zeolite runner is the equipment handled for the exhaust gas to enterprise, can be effectively by volatilization using zeolite runner Property organic exhaust gas is purified, it is the wheel device that zeolite sorptive material is fabricated to honeycomb structure.Volatility is organic After exhaust gas is by hydrophobic zeolite concentration runner, it can effectively be adsorbed in zeolite, achieve the purpose that removal.It is adsorbed by zeolite Volatile organic matter clean gas, directly by smoke stack emission to air.
Zeolite runner generally continues to rotate with the speed that 1-6 per hour turns, can artificially be divided on zeolite runner adsorption zone, Area, cooling renewing zone is desorbed.Wherein:
Volatile organic waste gas passes through adsorption zone, and the volatile organic matter in exhaust gas is concentrated by zeolite to be adsorbed, and exhaust gas is net Change, air can be directly discharged by purified clean gas;With the rotation of zeolite runner, volatility has been adsorbed in concentration to be had The adsorption zone of machine object is transferred to desorption area, is desorbed in area and volatile organic matter is desorbed using a small gangs of heat gas, is desorbed Concentration organic waste pneumatic transmission afterwards to incinerator carries out burning conversion in carbon dioxide and moisture discharge to air;Desorption is completed Zeolite runner is rotated to cooling zone afterwards, and boasting cooling zone with normal temperature air is cooled to room temperature, then is rotated to Adsorption Concentration area and carried out Absorption so recycles.
But since the processing air quantity of separate unit zeolite runner is limited, concentration ratio is also limited, if only using separate unit zeolite runner It handles, may cause zeolite runner that cannot concentrate the volatile organic matter in absorption exhaust gas completely so that VOCs treatment Not exclusively, the requirement of environmental protection is not achieved.
If using active carbon purifying waste gas to cause activated carbon demand huge since the plant gas scale of construction is huge merely, give up Gas disposal it is of high cost.
