Description
Technical Field
The utility model relates to the technical field of zeolite concentration rotating wheels, in particular to a novel zeolite concentration rotating wheel with a multilayer structure.
Background
For low-concentration organic waste gases (VOCs), under the condition of large air volume (such as printing factories, workshops and the like), the recovery and other measures are carried out to prevent pollutants from diffusing into the atmosphere, the required equipment is extremely large, so the operation cost for treating the VOCs is very expensive, the economic pressure for enterprises is high, the investment in the aspect of treating tail gas is insufficient, and the tail gas emission does not accord with the national standard, and the environment is polluted. The zeolite runner system is developed from the eighties of the last century and is gradually applied to the field, organic waste gas (VOCs) with low concentration and large air volume can be concentrated and absorbed for recovery, and finally pollutants are destroyed by an incineration technology, so that the zeolite runner system is mainly used for treating industrial organic waste gas. In treating organic waste gas with low concentration and large air quantity, the zeolite runner technology is one of the most economic means, and the effect is extremely good. The zeolite molecular sieve is installed into cylindrical rotating wheel, which is divided into adsorption zone, desorption zone and cooling zone, and the zeolite rotating wheel rotates at certain rotation speed and continuously and repeatedly rotates in each zone. Waste gas enters an adsorption area of the zeolite molecular sieve through the air inlet pipeline, volatile organic compounds in the waste gas can be adsorbed due to the characteristics of zeolite, the waste gas is purified, and the purified gas is discharged to the atmosphere from the exhaust pipeline. The volatile organic compounds adsorbed in the zeolite rotating wheel are blown off and desorbed when meeting preheated gas in the desorption area, and are destroyed in a subsequent combustion device. The zeolite rotating wheel is cooled in the cooling area and is recovered to be reusable, and heat can be recycled.
The key point of the rotating wheel technology is the adsorption capacity of the molecular sieve, whether the hydrophobicity is excellent or not determines the quality of the device under the condition of ensuring the large specific surface area, and then the humidity of a factory with high exhaust gas humidity is more than 60 percent, so that great examination is made on the hydrophobicity of zeolite. The zeolite having poor hydrophobicity causes the fine pores of the molecular sieve to be occupied by moisture, and prevents the exhaust gas from contacting the zeolite, thereby reducing the adsorption efficiency. In actual operation, the problem of zeolite blockage is always the cause of low purification efficiency.
