Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment.

[0014] The technical scheme of the present invention is to put the saturated granular activated carbon into the rotary stainless steel furnace and heat it to 500 0 C—600 0 C, let the adsorbed esters and impurities burn and ash. The temperature can be measured with a platinum-rhodium thermocouple thermometer. Avoid burning activated charcoal. After natural cooling, put the charcoal into a stainless steel 0.54 cubic meter carbon column, and pour in deionized water to wash the soluble matter and ash. For this purpose, rinse off, release the remaining water, pass through 0.3-0.5 MPa high-pressure steam to activate at high temperature for 1 hour, then dry in a rotary oven, the moisture content is less than 6%, measure the iodine absorption rate after cooling, sieve and classify and pack. Coarse granular activated carbon is used; finely crushed activated carbon is powdered.

Abstract

The technical scheme of the invention relates to a regeneration method for absorbed and saturated granular active carbon of processing base liquor, which comprises the steps of: combusting and ashing absorbed substances, which mainly comprises higher aliphatic acids as well as incendive substances, such as ethyl palmitate, ethyl oleate, ethyl linoleate and the like, of the absorbed and saturated granular active carbons of the processed base liquor at the high temperature 500-6000 DEG C; measuring the iodine absorption rate after the saturated granular active carbons are subjected to washing, activating by high temperature steam, drying and cooling; sieving and grading packaging the processed absorbed and saturated granular active carbons; and using coarse active carbons as granular active carbons and fine active carbons as powder active carbons after crushing. Therefore, the regeneration purpose is realized.

Description

technical field [0001] The invention relates to activated carbon, in particular to a method for regenerating granular activated carbon for treating base wine with saturated adsorption. Background technique [0002] Activated carbon is a hydrophobic adsorbent prepared by high-temperature carbonization and activation from carbon-containing substances as raw materials. Activated carbon contains a large number of micropores and has a huge specific surface area, which can effectively remove color and odor, and can remove most organic pollutants and some inorganic substances in the secondary effluent, including some toxic heavy metals. The factors affecting the adsorption of activated carbon are: the characteristics of activated carbon; the characteristics and concentration of adsorbed substances; the pH value of wastewater; the characteristics of suspended solids content; contact system and operation mode, etc. Special charcoal for alcohol accelerates the maturation and aging of...
