Description

A kind of airstrainer for wheat flour milling workshop
Technical field
The utility model relates to a kind of airstrainer, is specifically related to a kind of airstrainer for wheat flour milling workshop.
Background technology
Around wheat flour job shop, the pollutant containing in air has: flue dust, overall suspended pellet, can suck suspended particulate substance (floating dust), nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, VOC etc., outdoor air directly enters workshop, the pollutants such as airborne dust, insect can enter workshop polluted product in ventilating, and this is obviously between modernization food car and hygienic requirements forbids having this phenomenon.And shop material carries employing strength to carry, need ozone constantly to supplement into, the air in workshop constantly discharges.
Within 2003, country has promulgated the Law of the People's Republic of China on Promoting Clean Production, this method is like this definition: the measures such as cleaner production refers to and constantly takes to improve design, uses the clean energy and raw material, employing advanced person's technology and equipment, improvement management, comprehensive utilization, put down the pollution from headstream, improve the level of resources utilization, reduce or avoid generation and the discharge of pollutant in production, service and product use procedure, to alleviate or to eliminate the harm to human health and environment.According to the thought of this method, we no fall adopt the idea of force ventilation, determine to adopt gravity-flow ventilation.
But gravity-flow ventilation faces again the uncleanly problem of air, if the not treated workshop that directly enters of dust laden air, that airborne polluter will enter workshop flour is polluted, and directly enters the air wind speed shakiness in wheat flour milling workshop, suddenly big or suddenly small.
NACF be through overactivation containing charcoal fiber, through high-temperature activation, make its surface produce nano level aperture certain carbon fiber-containing, increase specific area, thereby change its physicochemical characteristic.Traditional active carbon is a kind of porous charcoal through activation processing; for Powdered or graininess; NACF is fibrous; on fiber, be covered with micropore; it is higher several times to tens times in air than granular activated carbon to organic gas adsorption capacity; high 5 ~ 6 times in the aqueous solution, fast 100 ~ 1000 times of the rate of adsorption, it is the sorbing material of a new generation after active carbon.Its goods can be the forms such as silk, paper, felt, cloth.But because its weight is extremely light, its goods cost just slightly increases.Remove to reclaim organic solvent in the industrial superpower adsorption capacity of utilizing it, purify air, purify water.For air cleaning, the compound that can effectively remove various harmful rotten material, especially carcinogens, the fragrant same clan in air can make air cleaning pure and fresh.
In the master thesis " anti-microbial property of shitosan, iodine and the application in the antibacterial processing of NACF thereof " of Dong Derong, disclose the preparation method of a kind of year iodine NACF and a kind of preparation method of shitosan-iodine composite active carbon fibre, within described year, iodine active carbon fibre peacekeeping shitosan-iodine composite active carbon fibre all can be used as the screen pack with bacteriostasis.
In the patent of invention " antibacterial active carbon fiber that chitosan porous membrane is coated and preparation method thereof " that Granted publication number is CN1840774, introduce " preparation method of the coated antibacterial active carbon fiber of chitosan porous membrane ", the coated antibacterial active carbon fiber of described chitosan porous membrane can be used as the screen pack with bacteriostasis, in this patent, referred to as carrying shitosan NACF.
Summary of the invention
For addressing the above problem, the utility model provides a kind of airstrainer for wheat flour milling workshop.
A kind of airstrainer for wheat flour milling workshop, ecto-entad comprises nonwoven layer, spongy layer, active carbon layer, wherein active carbon layer is fibrous by two-layer nonwoven coating active charcoal, described NACF is one or more of carrying in iodine NACF, year shitosan NACF or shitosan-iodine composite active carbon fibre, and wherein nonwoven layer, spongy layer and active carbon layer are sewed up and are connected by the grid of 100mm × 100mm.
Further, the thickness of described spongy layer is 10 ~ 50mm.
The described airstrainer for wheat flour milling workshop is installed on the window in wheat flour milling workshop, and in order not affect daylighting, part window uses, further, the quantity that described airstrainer is installed be not less than wheat flour milling workshop window sum 1/3.
Enter the dust laden air in wheat flour milling workshop with described airstrainer processing, first by nonwoven layer, air is carried out to primary filter, dispose large particle, adsorb to fall airborne part moisture, dust by spongy layer again, finally enter active carbon layer, year iodine NACF, year shitosan NACF or shitosan-iodine composite active carbon fibre of active carbon layer can not only adsorb to fall airborne molecule, chemical gas, peculiar smell, and this active carbon layer has antibacterial effect, breeding that can anti-bacteria.
The beneficial effects of the utility model are: (1) good filtration effect, and the air after this air filtration net filtration, reaches country-level standard; (2) controlled wind speed, stablizes the wind speed that enters wheat flour milling workshop, and this airstrainer is installed, and the air quantity that enters wheat flour milling workshop can be controlled to 146000m 3/ h; (3) directly enter wheat flour milling workshop with respect to air, this airstrainer also has heat insulation function.
