Abstract
The utility model provides a VOCs ((Volatile Organic chemicals)) waste gas processing system in a printing technology. The VOCs waste gas processing system mainly comprises a gas collecting cover, a heating chamber, a sintered metal catalytic purifier and a chimney. The sintered metal catalytic purifying device which takes a sintered metal powder microporous filter material as an adsorbing material and takes a catalyst substrate and CuMn/Gama-Al2O3 as a catalyst can realize the aim of effectively removing the VOCs waste gas. After the sintered metal catalytic material is prepared into a metal filter, the removal rate on benzene, toluene and dimethylbenzene can be higher than 99%, the VOCs waste gas in the printing technology can achieve the standard before being exhausted; therefore, the VOCs waste gas processing system has extremely wide application prospect.
Description
Technical field
The utility model relates to a kind of exhaust treatment system, and VOCs exhaust treatment system in particularly a kind of typography belongs to field of environment protection.
Background technology
In recent years, the development of the printing industry of China is swift and violent.A large amount of solvent type inks that use wherein contain a large amount of organic solvents in the printing process.The gas that these organic solvents volatilized, promptly VOCs gas is extremely harmful to health, can the liver and the nervous system of human body be caused damage.VOCs can damage the ozone layer, with generation chemical reactions such as NOx and form photochemical fog under certain meteorology, geographical conditions.The VOCs pollution control technology is divided into two big classes basically: the first kind is to improve technology, the more preventive measure revealed of exchange device and preventing; Second class is the controlled measure based on end treatment.Up to now, the terminal control technology of VOCs that has been successfully applied to practice mainly contains absorption method, condensation method, membrane separation process, photocatalytic degradation method, biological degradation method, plasma technique, directly firing method, Production by Catalytic Combustion Process etc.
Beijing has implemented new atmosphere pollutants emission standards, i.e. " discharge standard of air pollutants " DB11/501-2007 on January 1st, 2008.In the new discharge standard of air pollutants in Beijing the concentration limit of VOCs polluter than the national standard strictness many.Before 2008, be in the printing enterprise in Beijing suburban country and district Industry Development Area, to the VOCs that produces in the printing process, general only to after its centralized collection with after the filtrate adsorption treatment such as active carbon, discharge in a organized way in high-altitude, factory building top and can satisfy emission request.After the new atmosphere pollutants emission standards in Beijing is implemented, the problem of then insurmountable VOCs qualified discharge.
Summary of the invention
It is sorbing material and catalyst matrix, CuMn/ γ-Al with the sintering metal powder micropore filter material that the purpose of this utility model provides a kind of
2O
3Be VOCs exhaust treatment system in the typography of the sintering metal arrangement for catalytic purification of catalyst.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is a VOCs exhaust treatment system in a kind of typography, mainly comprises gas skirt, heating clamber, sintering metal catalytic cleaner and chimney.
Described VOCs waste gas through the heating clamber preheating, enters the sintering metal catalytic cleaner behind the gas skirt collection, after the purified treatment finally through the chimney high altitude discharge.
Described sintering metal catalytic cleaner is made up of the sintering metal catalytic adsorption material, is to be sorbing material and catalyst matrix, CuMn/ γ-Al with the sintering metal powder micropore filter material
2O
3Sintering metal powder micropore filter material for catalyst;
The utlity model has following advantage and positive effect:
In the typography that provides by above-mentioned the utility model the VOCs exhaust treatment system as can be seen, it is sorbing material and catalyst matrix, CuMn/ γ-A1 that the utility model adopts with the sintering metal powder micropore filter material
2O
3Be the sintering metal arrangement for catalytic purification of catalyst, can realize effective removal VOCs waste gas.
The utility model is by on-site verification, and about 300 ℃, after VOCs gas passed through the metallic filter of being made by the sintering metal catalysis material, the clearance of benzene,toluene,xylene all was higher than 99%.After metallic filter was handled, the concentration of emission of benzene,toluene,xylene can be lower than the emission limit discharging among the DB11/501-2007 of Beijing's " discharge standard of air pollutants ".
In recent years, the application study of sintering metal catalysis material mainly concentrates on fields such as coal gas of high temperature, exhaust gas from diesel vehicle post processing both at home and abroad.Be used for the purification of VOCs for the sintering metal catalysis material, up to now, the Shang Weiyou report.The reason that produces this situation mainly is because the price discharge standard higher and original VOCs of sintered metal materials is comparatively loose.Along with the enforcement of the new atmosphere pollutants emission standards in Beijing and the production in enormous quantities of sintering metal catalysis material, the application prospect of this method will be very broad.

Accompanying drawing is the process chart of VOCs exhaust treatment system in the utility model typography.
VOCs exhaust treatment system process chart in Fig. 1 typography
The 1-gas skirt; The 2-heating clamber; 3-sintering metal catalytic cleaner; 4-sintering metal catalytic purification material; The 5-chimney; 6--VOCs; Waste heat in the 7-workshop.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As figure, the utility model is a VOCs exhaust treatment system in a kind of typography, mainly comprises gas skirt 1, heating clamber 2, sintering metal catalytic cleaner 3 and chimney 5.
The course of work that the utility model is handled coal bed gas produced draining is:
After system brings into operation, VOCs waste gas 6 is after gas skirt 1 is collected, and heating clamber 2 preheatings of waste heat 7 enter sintering metal catalytic cleaner 3 in thermal source is the workshop, sintering metal catalytic cleaner 3 is made up of sintering metal catalytic adsorption material 4, after the purified treatment finally through chimney 5 high altitude discharges.
The sintered metal powders powder material is made through operations such as alloy melting, powder by atomization, compacting or rolling, sintering, is a kind of poromerics of asymmetry structure.The organic exhaust gas that contains VOCs is through rational cloth wind, and evenly by the flow section of sintered metal powders powder material, in certain time of staying, intermolecular the attracting each other of sintered metal powders powder material and organic exhaust gas produces suction-operated (being adsorbed as the master with Van der Waals).The VOCs organic exhaust gas obtains the part removal by the suction-operated of sintered metal powders powder material.Simultaneously, the sintered metal powders powder material also can make the dust in the waste gas be removed.
The sintering metal catalysis material of attached catalyst can make VOCs carry out flameless combustion under lower initiation temperature, and making VOCs organic exhaust gas combustion decomposition is carbon dioxide and steam, and emits a large amount of heats.
