3 Terms and definitions
The following terms and definitions apply to this standard.
3.1 Industrial organic emissions
Refers to gaseous pollutants containing volatile organic compounds emitted by industrial processes.
3.2 Explosion limit explosive limit
Also known as the explosive concentration limit. Refers to the concentration range in which a combustible gas or vapor can be combined with air to explode.
3.3 Lower explosive limit lower explosive limit
Refers to the lowest concentration value of the explosion limit.
3.4 Activated carbon fiber felt activated carbon fiber felt
Refers to a porous material prepared by carbonization and activation of a fiber mat processed by viscose, polyacrylonitrile or pitch fiber.
3.5 Honeycomb activated carbon
Refers to the powdered activated carbon, water-soluble binder, lubricant and water, etc. after being compounded, kneaded, extruded, and then dried, charred,
Honeycomb adsorbent material prepared after activation.
3.6 Honeycomb molecular sieve honeycomb-type molecular sieve
Refers to the powdered molecular sieve, water-soluble binder, lubricant and water, etc. after being compounded, kneaded, extruded, and then dried and activated.
a honeycomb adsorbent material produced later; or a slurry prepared by using a powdery molecular sieve, a water-soluble binder, and water, is coated on the fiber material,
A honeycomb-like adsorbent material made by folding and drying.
3.7 BET specific surface area BET specific surface area
Refers to the surface area per unit mass of adsorbent tested by the BET method, in m2/g.
3.8 Fixed bed adsorption device fixed bed adsorber
Refers to the adsorption device in which the adsorbent layer is in a stationary state during the adsorption process.
3.9 moving bed adsorption device moving bed adsorber
It refers to the continuous passage of the adsorbent in a certain manner, and sequentially completes the adsorption, desorption and regeneration and re-enters the adsorption section of the adsorption section.
3.10 fluidized bed adsorption device fluidized bed adsorber
Refers to the adsorption device in which the adsorbent is strongly agitated under the action of high-speed airflow during the adsorption process, and the fluid is in a fluidized state.
3.11 Rotary wheel adsorber
Refers to a circular adsorption device with a certain thickness prepared by using granular, felt or honeycomb adsorption materials, driven by motor
The movement is divided into an adsorption zone, a regeneration zone and a cooling zone on the entire circular fan surface, and the polluted air is adsorbed and purified through the adsorption zone, and the pollution is adsorbed.
After the region of the object is rotated to the regeneration zone, it is regenerated by the hot air flow, and the regenerated high temperature zone is rotated to the cooling zone and then cooled by the cold airflow.
The adsorption and regeneration of the adsorbent are carried out in this cycle.
3.12 dynamic adsorption capacity
Refers to filling a certain amount of adsorbent into the adsorption column, so that a certain concentration of polluted air flows at a constant speed under constant temperature and constant pressure, when sucking
When the concentration of the pollutant in the outlet of the column reaches the set value, the average adsorption amount of the adsorbent per unit mass to the pollutant is calculated. Average adsorption amount
