Embodiment 1

[0026] Combine figure 1 A purification system for purifying VOCs in the air of this embodiment includes a heating device 2, a purification tower 3, a dust collector 4, and an exhaust fan 5; the bottom of the purification tower 3 is provided with an air inlet 1 to purify The lower area of ​​the tower 3 is provided with a heating device 2, the heating device 2 is an electric heater, the purification tower 3 is filled with adsorbent, and the top of the purification tower 3 is connected to the inlet end of the dust collector 4 through a pipe to remove dust The device 4 can further remove dust and purify the gas in the purification tower 3, preventing particulates from entering the atmosphere to pollute the environment. The outlet end of the dust remover 4 is connected with an exhaust fan 5, and an air outlet 6 is provided at the end of the exhaust fan 5.

[0027] The components of the adsorbent are composed of the following parts by mass: 30kg of activated alumina, 40kg of activated ...

Embodiment 2

[0048] In the purification system of this embodiment for purifying VOCs in the air, each component of the adsorbent is composed of the following mass parts: 35kg of activated alumina, 55kg of activated carbon, 18kg of iron ore powder, and 15kg of pelletized sieving , Biomass material 12kg, magnesia laterite nickel ore 3kg, kaolin 8kg, additives 20kg. The creative composition ratio and the special particle size composition of activated alumina and activated carbon make the adsorbent have a higher porosity and specific surface area. When VOCs contact the adsorbent, the adsorbent can fully contact the VOCs, which is beneficial to the VOCs. The removal, while increasing the specific surface area, further improves the adsorption capacity of the adsorbent.

Abstract

The invention discloses a purification system for removing VOCs (Volatile Organic Chemicals) from air, and belongs to the field of atmosphere VOCs control. The purification system comprises a heating device, a purifying column, a dust remover and an exhaust fan, wherein a gas inlet is formed in the bottom of the purifying column; the heating device is arranged at the lower part area of the purifying column; an adsorbent is filled inside the purifying column; the top of the purifying column is connected with an inlet end of the dust remover through a pipeline; an outlet end of the dust remover is connected with the exhaust fan; a gas outlet is formed in the tail end of the exhaust fan; the adsorbent is prepared from activated aluminum oxide, activated carbon, iron ore powder, pellet sieve residues, a biomass material, a magnesia-based laterite-nickel ore, kaolin and an additive. According to the purification system disclosed by the invention, the purifying column is arranged, the adsorbent is filled inside the purifying column, and the heating device is arranged at the lower part of the purifying column, so that under the heating condition, the metal catalyst in the adsorbent can be used for catalyzing and decomposing VOCs, in addition, the adsorbent can effectively adsorb the VOCs, and the high-efficiency low-cost removal of VOCs can be realized.

Description

Technical field [0001] The present invention relates to the field of treatment of VOCs in the atmosphere, and more specifically, to a purification system for purifying VOCs in the air. Background technique [0002] VOCs usually refer to organic chemical substances with high vapor pressure and volatile under normal temperature and pressure, mainly including alkanes, alkenes and aromatic hydrocarbons, as well as various oxygenated hydrocarbons, halogenated hydrocarbons, nitrogen hydrocarbons, sulfur hydrocarbons, and low boiling points. Cycloaromatic hydrocarbons, etc., are a type of organic pollutants that are ubiquitous and complex in the air. As VOCs involve many types, their physical and chemical properties are diverse and have certain potential hazards. Some highly active VOCs can undergo photochemical reactions with nitrogen oxides under certain conditions, causing an increase in the surface ozone concentration, forming photochemical smog pollution, or reacting with some fre...
