Description
Technical field
The present invention relates to energy-saving and emission-reduction, how specially intaglio press air circulation system efficiently improves intaglio printing
VOCs concentration in machine discharge waste gas, it is to avoid block letter surface ink is too fast to dry surface cure, the solvent in block letter curing ink
Can successfully volatilize.
Background technology
Exactly be coated in printed body ink and then drying by current intaglio printing, and solvent-borne type oil is generally taken so far
Ink, the i.e. ink containing VOCs, the ink containing VOCs can produce the substantial amounts of gas containing VOCs in drying course.Because VOCs is
After producing the precursor of atmospheric haze, VOCs to be discharged into air under sunlight irradiation can and NOxization present in air
Learn reaction generation PM2.5 and have the ozone of injury to human body, China has taken up the discharge that severe regulation means limit VOCs,
The VOCs for destroying gravure printing process discharge using heating power oxidation or catalytic oxidation technologies is considered as maximally effective attenuating intaglio plate
Printing VOCs pollutes one of maximally effective technological means.
Although can reduce VOCs using water-based ink to discharge, it is complete in intaglio printing due to technology and economic cause
Face needs the regular hour using water-based ink.The VOCs pollution technologies how development eliminates existing ink generation are particularly significant.
Using oxidation technology, it is that a kind of highly effective VOCs eliminates skill to eliminate VOCs comprising heating power oxidation and catalysis oxidation
Art.It is exactly VOCs is resolved into the water being had no adverse effect to environment at a temperature of 700 DEG C or so that heating power oxidation eliminates VOCs
With carbon dioxide, and catalytic oxidation technologies are exactly VOCs is changed at relatively low temperatures to environment under catalyst action
The water and carbon dioxide having no adverse effect.
No matter heating power oxidation eliminates VOCs or catalysis oxidation eliminates VOCs, the cost of investment of equipment with need to wind to be processed
Amount is relevant, and air quantity is bigger, and cost of investment is higher.In addition, no matter heating power oxidation eliminates VOCs or catalysis oxidation elimination VOCs, give up
The concentration of VOCs influences the operating cost of equipment in gas.Thus, in reduction intaglio press discharge air quantity and raising intaglio printing
VOCs concentration, is the key for economically eliminating intaglio printing VOCs pollutions.
In addition, when being printed using solvent-based ink, on printed matter dissolvent residual be perplex intaglio printing major issue it
One, how to reduce the dissolvent residual on printed matter is also the problem that intaglio printing industry must be solved.
The content of the invention
It is an object of the invention to be directed to above-mentioned problem and shortage, there is provided a kind of efficiently to improve intaglio press row
To avoid, block letter surface ink is too fast to dry surface cure to VOCs concentration in putting waste gas, so that the solvent in block letter curing ink
Can successfully be volatilized the intaglio press air circulation system that intaglio press discharges air quantity that reduce simultaneously.
Above-mentioned purpose of the invention is to be achieved by the following technical programs:
Intaglio press air circulation system, including some groups of print couple X n (n=1,2,3.........), air exhauster MB,
VOCs concentration detectors;
Every group of print couple includes return air regulating valve An (n=1,2,3.........), colour cell breeze fan Cn (n=1,2,
3.........), fresh air replenishment valve Dn (n=1,2,3.........), evacuating air regulating valve En (n=1,2,
3.........), and printing drying tunnel Bn (n=1,2,3.........), air heating heat exchanger Hn(n=1、2、.....);
Technical scheme one, each group print couple is in parallel, and every group of print couple exhaust outlet connects total exhaust duct, total air draft pipe end point
Two branch roads a, branch road leads to each print couple with circulation return air, and another branch road connects air exhauster MB and VOCs Concentration Testing instruments
After empty, air exhauster MB is located at the overall top of intaglio press air circulation system;
Colour cell breeze fan Cn (n=1,2,3.........) air inlet respectively by fresh air replenishment valve Dn (n=1,2,
3.........)Connection air inlet, by return air regulating valve An (n=1,2,3.........) and total air escape pipe branch road phase
It is logical.
Technical scheme two, each group print couple is in parallel, and every group of print couple exhaust outlet connects total exhaust duct, on total exhaust duct
If leading to the branch road of each print couple with circulation return air, exhaust duct tail end is by air exhauster MB and VOCs Concentration Testing instrument heel row
Sky, air exhauster MB is located at intaglio press air circulation system entirety bottom;
Colour cell breeze fan Cn (n=1,2,3.........) air inlet respectively by fresh air replenishment valve Dn (n=1,2,
3.........)Connection air inlet, is communicated by return air regulating valve An (n=1,2,3.........) with total air escape pipe.
Above technical scheme is adjusted according to every group of size adjustment fresh air valve valve of printing drying tunnel surface covered and return air
Solvent strength is to ensure economy and the printing of follow-up exhaust-gas treatment in saving the relative scale control printing drying tunnel of valve valve
Operated under conditions of away from explosion ratio.
The evaporation in block letter of solvent in ink, it is necessary to meet two conditions simultaneously, first, evaporation need heat,
It is currently that block letter is transferred heat to by drying tunnel recirculated hot air, drying tunnel return air quantity is bigger, and heat transfer speed is got over
Hurry up, the evaporation rate of solvent that printing is put on increases;Need to set up block letter surface VOCs concentration and circulation air when the second, evaporating
Concentration difference between VOCs concentration, evaporation rate of solvent is faster in the bigger block letter of concentration difference.
Air exhauster MB runs air quantity and is controlled by VOCs Concentration Testings instrument, and air exhauster MB frequencies are adjusted according to VOCs concentration
Rate, if the VOCs concentration for detecting is less than setting value, air exhauster MB running frequencies decline, when the VOCs concentration for detecting is higher than
Setting value, air exhauster MB running frequencies rise.
Every group of print couple gas exhaust piping installs valve for air exhaust, in certain group or idle a few groups of print couples,
The correspondence valve for air exhaust of print couple, return air regulating valve valve and fresh air replenishment valve valve all in closed mode, with
The exhaust air rate for reducing printing machine and the concentration for increasing VOCs in discharge waste gas.
The present invention uses above-mentioned structure design, its advantage to show as:
1st, printing drying tunnel circulation air is extracted from exhaust, and VOCs concentration is increased considerably in drying tunnel circulation air, prints surface
The concentration difference that solvent evaporation needs declines, and thus evaporation rate of solvent reduction avoids the too fast surface that dries of block letter surface ink from consolidating
Change, the solvent in block letter curing ink can successfully volatilize, thus, the printing drying tunnel round-robin method for taking the present invention to describe can
So that the dissolvent residual in block letter is greatly lowered;
2nd, certain group print couple it is idle when, correspondence print couple on all valve closings, printing machine exhaust air rate by
This declines.In addition, exhaust air rate is controlled by VOCs concentration, total exhaust air rate is easy to control.
