Abstract
The invention discloses an activated carbon cloth filter which comprises a granular activated carbon layer, wherein both sides of the granular activated carbon layer are respectively compounded with a composite non-glue cotton layer and a glass fiber nonwoven fabric layer. The carbonizing treatment of the activated carbon comprises the following steps: heating from 157 DEG C to 295-305 DEG C in a low-temperature heat treatment furnace at the heating rate of 4-12 DEG C/minute, keeping the temperature constant for 6-15 minutes, heating to 310-330 DEG C, cooling to 85 DEG C below, and charging nitrogen at the inlet and outlet of the low-temperature heat treatment furnace to perform gas sealing. The cloth filter has the advantages of reasonable structure, favorable filtering quality and wide application range.
Description
Technical field
The present invention relates to a kind of absorbent charcoal material.
Background technology
, due to reasons such as structures, there is defect at the aspect such as strainability, the scope of application in existing activated carbon filtration material.
Summary of the invention
The object of the present invention is to provide one rational in infrastructure, the active carbon filter cloth that strainability is good.
Technical solution of the present invention is:
A kind of active carbon filter cloth, is characterized in that: comprise granular activated carbon layer, the both sides of granular activated carbon layer are compound hot air cotton layer and glass nonwoven layer respectively; When active carbon charing is processed, Low Temperature Heat Treatment stove is since 175 ℃ of intensifications, intensification 4-12 ℃ per minute, be warming up to 295-305 ℃, then after constant temperature 6-15 minute, be warming up to 310-330 ℃ again, be then cooled to temperature lower than 85 ℃, the import and export of Low Temperature Heat Treatment stove add nitrogen sealing gland.
Filter cloth thickness is 1.8mm; When active carbon charing is processed, Low Temperature Heat Treatment stove is since 175 ℃ of intensifications, and 7 ℃ of intensifications per minute, are warming up to 295 ℃, and then constant temperature is warming up to 310 ℃ again after 7 minutes, is then cooled to temperature lower than 85 ℃, and the import and export of Low Temperature Heat Treatment stove add nitrogen sealing gland.
Filter cloth thickness is 2.3mm; When active carbon charing is processed, Low Temperature Heat Treatment stove is since 175 ℃ of intensifications, and 8 ℃ of intensifications per minute, are warming up to 299 ℃, and then constant temperature is warming up to 313 ℃ again after 8 minutes, is then cooled to temperature lower than 85 ℃, and the import and export of Low Temperature Heat Treatment stove add nitrogen sealing gland.
The present invention is rational in infrastructure, and strainability is good, and the scope of application is wide.
Below in conjunction with embodiment, the invention will be further described.
