Abstract
The invention discloses a rice hull modified lampblack filtering material. The rice hull modified lampblack filtering material is characterized by being prepared from, by weight, 60-80 parts of polypropylene resin, 10-15 parts o f rice hulls, 3-5 parts of kieselguhr, 3-5 parts of hydroxyethyl cellulose, 10-20 parts of bamboo fibers, 10-20 parts of ferric chloride, 1-2 parts of abietic acid polyoxyethylene, 2-4 parts of liquid paraffin, 1-2 parts of polytetrafluoroethylene micro powder and 50-100 parts of impregnation liquid. The lampblack filtering material is good in holding and filtering performance on particulate pollutants, meanwhile, the adsorption performance on poisonous and harmful components in oil fume is enhanced, complex oil fume pollutant components are effectively removed, and human health and environmental protection are facilitated.
Description
Technical field
The present invention relates to filtering oil smoke Material Field, be specifically related to a kind of rice husk modification oil smoke filtering material and preparation method thereof.
Background technology
In recent years, along with expanding economy, hotel industry development is rapid, also day by day comes into one's own to the control of oil smoke of catering industry discharge.The standard that country issues also requires catering enterprise's oil smoke qualified discharge, avoids affecting environmental and human health impacts.Such as the electrostatic precipitation etc. of the oil smoke treatment measures of some routines is subject to the restriction of place, fund usually, and mechanical filter method has cost is low, efficiency is high, easy to install feature, meet the actual demand of more small-sized food and beverage enterprise.Containing solid, liquid two kinds of particles in cooking oil flue gas, simultaneously containing multiple toxic chemicals, to body, there is Cancer-causing mutation, immunotoxicity, harmful effect is caused to the health of resident and environmental sanitation.And traditional filtering material cannot the cooking fume pollutant component of comprehensive decontamination relative complex, the scope of application is narrower, and application is restricted.
Summary of the invention
The object of this invention is to provide a kind of rice husk modification oil smoke filtering material, effectively can purify complicated cooking fume pollutant component.
The present invention is achieved by the following technical solutions:
A kind of rice husk modification oil smoke filtering material, it is obtained by the raw material of following weight parts:
Acrylic resin 60-80, rice husk 10-15, diatomite 3-5, hydroxyethylcellulose 3-5, bamboo fibre 10-20, iron chloride 10-20, polyoxylethylene abietate 1-2, atoleine 2-4, ptfe micropowder 1-2, maceration extract 50-100;
Maceration extract is wherein made up of the raw material of following weight portion: cornstarch 5-10, Dodecyl Polyglucosides 1-2, polyethylene glycol 1-2, Sodium Benzoate 1-2, water 100-150; Dodecyl Polyglucosides is first added to the water 600-800r/min to stir 5-10min by the preparation method of maceration extract, then adds all the other raw materials 60-80 DEG C, 400-600r/min stirs 1-2h, after cooling and get final product.
A preparation method for rice husk modification oil smoke filtering material, comprises the following steps:
(1) first by 300-400 DEG C of process 1-2h after the mixing of rice husk, diatomite and hydroxyethylcellulose, after cooling, grinding evenly, cross 400-600 mesh sieve, then the acetum immersion treatment 12-24h of 4-8% is used, filter, wash until pH is neutral, completely dry under 120-140 DEG C of condition, obtain mixed powder; Iron chloride is dissolved in suitable quantity of water, add mixed powder and stir under 40-60 DEG C of condition, filter after insulation 1-2d, wash until pH is neutral, then completely dry under 120-140 DEG C of condition, obtain modified powder;
(2) by evenly blended for the modified powder high speed in acrylic resin, polyoxylethylene abietate, atoleine, ptfe micropowder and (1), double screw extruder extruding pelletization is used under 180-220 DEG C of condition, then melt spinning, obtains composite fibre after coiling and molding;
(3) shredding after the composite fibre in (2) and bamboo fibre being mixed, laying become net, and hot-forming, then impregnation process 12-24h in maceration extract, cuts rolling after drying, obtains rice husk modification oil smoke filtering material.
Advantage of the present invention is:
The present invention is using materials such as rice husks as carrier loaded iron oxide, in conjunction with the filtration cutoff performance of carrier material itself and the activated adoption characteristic of iron oxide, the active powder specific area obtained is large, porosity is high, has good cut-off filter, purifying functions to the harmful components in cooking fume and particulate pollutant; Active powder and acrylic resin batch mixing melt spinning are obtained modified polypropylene fiber; with bamboo fiber blended; be that the maceration extract of major ingredient carries out surface modification again with cornstarch; the obtained cut-off filter performance of filtering oil smoke material to particulate pollutant is good; enhance absorption property that is poisonous in cooking fume, harmful components simultaneously; effectively can purify complicated cooking fume pollutant component, be of value to health and environmental protection.
Detailed description of the invention
