Abstract
The invention relates to a manufacturing method of a function module used for absorbing fog drops and VOC (volatile organic compounds) in airflows and belongs to technical field of material preparation and environmental protection. The manufacturing method includes utilizing honeycomb paper as a base material, drilling holes at different positions of two adjacent partition layers, impregnating the honeycomb paper in pulp containing absorbent powder, taking the honeycomb paper out and drying to obtain the function module for absorbing fog drops and VOC in the airflows. The airflows pass in a baffling manner in the function module, the fog drops and the VOC are captured by absorbent on the inner wall of the honeycomb paper and the surface of a partition layer, so that the function module can efficiently remove the fog drops and the VOC in the airflows under the condition of lower pressure drop, and is more applicable to purification and treatment of catering waste gas.
Description
Technical field
The present invention relates to a kind of preparation method of the functional module for absorbing air-flow droplet and VOC, belong to material preparation and environmental protection technical field.
Background technology
Along with China's rapid development of economy, the grey haze air pollution of China big and medium-sized cities, developed area and basic industries close quarters is day by day serious.Along with China is increasingly strict for the restriction of SOx and NOx discharging, relevant green technology and installing constantly comes into operation, the gross contamination emission of SOx and NOx reduces year by year in China's atmospheric environment, yet, from present testing result, the grey haze of China's Yangtze River Delta, Pearl River Delta and each section, Beijing-Tianjin Ji pollutes and is on the rise on the contrary, and the common people's healthy and economic sustainable development has been arrived in serious threat.
Pollute going deep into of the research of tracing to the source along with current for grey haze, it has been found that, city volatile organic matter (VOC) is the important presoma that grey haze pollutes, and nearest research is found, the VOC of the life faces such as catering trade and finishing source emission in total VOC discharging proportion near 20%, because this type of discharging and human settlements density relationship are close, drain time is relatively concentrated, probably is one of arch-criminal of current city local air serious pollution simultaneously.
The a large amount of use of food cooking mode with Chinese characteristics fried in shallow oil, fry, the technique such as fried, contain in a large number the droplet that oil water mixture consists of in the waste gas that causes discharging, and VOC, this makes the smoke exhaust ventilator of common employing baffling method be difficult to eliminate fully oil smoke and the VOC that discharges, therefore a kind of simple and effective technical scheme of needs purifies the food and drink waste gas after smoke exhaust ventilator is processed, in addition, because the discharging of catering trade does not often have blower fan auxiliary, therefore the necessary pressure drop of this cleaning module is very low, therefore common ADSORPTION IN A FIXED BED method can't adopt because pressure drop is too large, although and fluid bed absorption method bed pressure drop is not high, but the distribution of gas anode drop of lower floor is larger, and generally cyclone separator need to be installed behind fluid bed, to remove the absorbent particles of escaping because of broken, this occasion for the food and drink exhaust-gas treatment is unacceptable often.
In sum, at present China needs that a kind of vapour lock is little, flux large badly, can effectively remove droplet in the catering trade waste gas and the technical scheme of VOC, and this is most important to the contribution that atmosphere ash haze pollutes for suppress catering trade from the source.
Summary of the invention
The object of the invention is to obtain to have the module of low vapour lock, high-throughout efficient removal droplet and VOC by a kind of simple method.This modular structure is compact, preparation method is simple, pressure drop is lower, all has certain capturing ability for the droplet in the food and drink waste gas, particulate and VOC.
The objective of the invention is to realize by the following technical solutions: the employing honeycomb card board is matrix, diverse location punching at adjacent carrier ring, again the paper honeycomb module is immersed in the slurry that contains absorbent powder, taking-up just obtains for the functional module that absorbs air-flow droplet and VOC by oven dry, the paper honeycomb that adopts is that the cross section is orthohexagonal paper honeycomb, and orthohexagonal external radius of a circle is 4mm ~ 200mm; Absorbent powder in the described method is a kind of or any several mixture in the middle of diatomite, active carbon powder, activated coke powder, chopped carbon fiber, chopped NACF, short glass fiber, active oxidation aluminium powder, molecular screen primary powder, zeolite powder, expanded vermiculite powder, imvite powder and the neatly stone flour; The solid content that is used for the slurry of load absorbent powder in the described method is 1wt% ~ 50wt%; The slurry that is used for the load absorbent powder in the described method contains adhesive, be used for adsorbent is sticked to keriotheca and carrier ring, adhesive be gelatinized starch, cation etherification starch, sodium carboxymethylcellulose, methylcellulose, molecular weight at the polyethylene glycol between 1000 ~ 2.5 ten thousand and molecular weight a kind of in the middle of the polyvinyl alcohol between 2.5 ten thousand ~ 300,000 or any several mixture, the mass concentration of adhesive in slurry is 0.1wt% ~ 5wt%.
Because the diverse location perforate at the adjacent separator layer of paper honeycomb, so containing the air-flow of droplet and VOC will pass through at the duct of multi-ply paper honeycomb infolding stream, greatly improve droplet and VOC and absorbed the probability that catches by keriotheca inwall and carrier ring, in addition since keriotheca inwall and carrier ring surface all load adsorbent is arranged, this has also improved the absorbability of module to VOC and droplet greatly, when droplet is more in the air-flow, can select diatomite, chopped carbon fiber, short glass fiber, the active oxidation aluminium powder, molecular screen primary powder, zeolite powder, expanded vermiculite powder, the higher powder of imvite powder or these oil factors of neatly stone flour is as the absorbent of functional module, the droplet of oil-containing water mixture in the absorption food and drink waste gas that like this can be more; When VOC was higher in the waste gas, can select active carbon powder, activated coke powder or chopped NACF was adsorbent, can effectively adsorb like this VOC in the waste gas.Which floor ordinary circumstance can settle first with diatomite, chopped carbon fiber, short glass fiber, the active oxidation aluminium powder, molecular screen primary powder, zeolite powder, expanded vermiculite powder, the powders such as imvite powder and neatly stone flour are the paper honeycomb layer of adsorbent, at first the droplet in the air-flow is removed fully, and then which floor settles with active carbon powder, activated coke powder or chopped NACF are the paper honeycomb layer of adsorbent, VOC remaining in the air-flow is removed, arrangement can be given full play to active carbon like this, the adsorbents such as activated coke are to the absorption property of VOC, and the droplet of avoiding them to be contained the thickness oil mixing with water covers and plug-hole.
