Embodiment 1

[0026] combine figure 1 , a purification system for purifying VOCs in the air of the present embodiment, comprising 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, and the purification The lower area of ​​the tower 3 is provided with a heating device 2, the heating device 2 is an electric heater, the inside of the purification tower 3 is filled with an adsorbent, and the top of the purification tower 3 is connected to the inlet port of the dust remover 4 through a pipeline, and the dust removal The device 4 can further dedust and purify the gas in the purification tower 3, preventing particles from entering into the atmosphere to pollute the environment.

[0027] The components of the adsorbent are composed of the following parts by mass: 30kg of activated alumina, 40kg of activated carbon, 15kg of iron ore powder, 10kg of pelletized ore sieve, 8kg of biomass material, ...

Embodiment 2

[0048] A kind of purification system for purifying VOCs in the air of the present embodiment, each component of described adsorbent is made up by mass parts as follows: 35kg of activated alumina, 55kg of activated carbon, 18kg of iron ore powder, 15kg of pelletizing sieve material , 12kg of biomass material, 3kg of magnesia laterite nickel ore, 8kg of kaolin, and 20kg of additives. The creative component distribution ratio, as well as the special particle size composition of activated alumina and activated carbon, make the adsorbent have high porosity and specific surface area. When VOCs are in contact with the adsorbent, the adsorbent can fully contact with VOCs, which is beneficial to VOCs 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 invention relates to the field of VOCs treatment in the atmosphere, and more specifically, relates to a purification system for purifying VOCs in the air. Background technique [0002] VOCs usually refer to volatile organic chemicals with high vapor pressure at normal temperature and pressure, mainly including alkanes, olefins and aromatic hydrocarbons, as well as various oxygen-containing hydrocarbons, halogenated hydrocarbons, nitrogen hydrocarbons, sulfur hydrocarbons, low boiling point and more Aromatic hydrocarbons, etc., are a class of organic pollutants that are ubiquitous in the air and have a complex composition. Since there are many types of VOCs involved, their physicochemical properties show diversity and have certain potential hazards. Some highly active VOCs can react photochemically with nitrogen oxides under certain conditions, causing an increase in the concentration of surface ozone to form photochemical smog pollution, and can a...
