Abstract
The invention provides an adsorbent for purifying organic waste gas, and a preparation method thereof. The adsorbent is prepared from, by weight, 40-60 parts of dry sludge, 40-50 parts of active carbon, 3-4 parts of polyvinyl alcohol, 3-4 parts of dioctyl sodium sulfosuccinate, 2-3 parts of glycerin, 5-6 parts of N,N-dimethyl formamide, 8-10 parts of modified attapulgite and a proper amount of water. The preparation method comprises the following steps: adding polyvinyl alcohol, dioctyl sodium sulfosuccinate, glycerin and DMF to the proper amount of water, stirring, grinding to obtain a 200-300 mesh slurry, adding dry sludge, active carbon and modified attapulgite, continuously grinding, carrying out ultrasonic drying, sending the obtained dried mixture to a heat treatment furnace, and treating to obtain the adsorbent. Dioctyl sodium sulfosuccinate and other organic matters are used to modify active carbon, so the use of active carbon is enlarged; and the dry sludge is adopted to substitute active carbon, so the addition amount of active carbon is reduced, raw materials are saved, and the waste dry sludge is reused and changes to valuables in order to reduce environment pollution.
Description
Technical field
The present invention relates to exhaust gas treatment technology, particularly relate to adsorbent of a kind of cleaning organic waste gas and preparation method thereof.
Background technology
Atmosphere pollution is one of the most outstanding at present environmental problem of China, and industrial waste gas is the important sources of atmosphere pollution.Large capacity industrial waste gas enters air, atmosphere quality must be made to decline, bring serious harm, bring about great losses to national economy to health.The most unmanageable in industrial waste gas is exactly organic exhaust gas, after organic exhaust gas enters human body by respiratory tract and skin, cause temporary and permanent pathology can to the organs and systems such as breathing, blood, liver of people, especially benzopyrenes polycyclic aromatic hydrocarbon can make human body directly carcinogenic, has caused the great attention of the mankind.Various organic compounds can be produced in industrial production, mainly comprise various hydro carbons, alcohols, aldehydes, acids, ketone and amine etc.; These organic exhaust gas can cause atmosphere pollution, are detrimental to health, but also can cause waste, so the process of organic exhaust gas is imperative with purification.
Organic exhaust gas is mainly derived from the waste gas discharged in petroleum and chemical industry industry production process, and feature is that quantity is comparatively large, and content of organics fluctuation is large, flammable, have certain toxicity, and what have goes back foul smelling, and the discharge of CFC also can cause the destruction of ozone layer.The storage facility of petroleum and chemical industry factory and petroleum chemicals, printing and other industries relevant with petroleum and chemical industry, use oil, the occasion of petrochemicals and combustion apparatus take oil product as the various vehicles of fuel is all the source of organic exhaust gas.Organic exhaust gas generally all exist inflammable and explosive, poisonous and harmful, water insoluble, be dissolved in organic solvent, feature that intractability is large.
Generally speaking, the processing method of organic exhaust gas mainly contains two classes: a class is absorption method.Absorption method passes through physical method, under uniform temperature, pressure, carry out separation of VOCs (VOCs) by the method such as selective absorbent and permoselective membrane, mainly comprise active carbon adsorption, pressure-variable adsorption, condensation method and biomembrance process etc.; Another kind of is null method.Null method is by chemistry or biological respinse, uses up, organic matter is converted into water and carbon dioxide by heat, catalyst and microorganism etc., mainly comprise thermal oxide, catalytic combustion, biological oxidation, corona method, plasma decomposition, light decomposition method etc.
Due to absorption method have that efficiency is high, purification thoroughly, be easy to promote practical, environmental benefit and the advantage such as economic benefit is good, adopt absorption method that the clearance of VOCs can be made up to 90% ~ 95%.But the key that absorption method reclaims V0Cs is that the screening of high-quality adsorbent is developed.Adsorbent should possess the features such as bigger serface, selective, the easy desorb of good adsorption, mechanical strength and wearability is good, long service life.Current industrial conventional adsorbent has active carbon, NACF, dewatering silica gel, mixed adsorbent etc., but new pollution likely introduced by these adsorbents, causes further broken evil to environment.
