Embodiment 1

[0034] In the normal purification process, the VOC exhaust gas in the factory building is detected by the VOC detector 1, and the detector displays the concentration of the exhaust gas. The operator controls the first exhaust pump 7 to exhaust outward, and the VOC exhaust gas enters the elastic through the first exhaust pipe 2. Airbag 8; or connect the VOC detector 1 detection and the first exhaust pump 7 and the second exhaust pump 34 with PLC to realize intelligent automatic control. After the VOC detector 1 detects the concentration of VOC exhaust gas in the factory building, it sends the concentration data To the PLC, after the PLC compares the concentration data with the preset data, if the preset data is exceeded, the first exhaust pump 7 and / or the second exhaust pump 34 are controlled to be turned on, and the VOC exhaust gas enters the elastic airbag 8 through the first exhaust pipe 2 ;

[0035] Under the action of the supporting frame, the elastic airbag 8 has a certa...

Embodiment 2

[0037] As an optimization of Embodiment 1, when the concentration of VOC exhaust gas in the factory building is high, the first exhaust pump 7 (can be a single high-power or multiple) will discharge Gas, because the entire purification system that VOC passes through is closed, when passing through the multi-layer fiber carbon adsorption bed 30 in the fiber carbon adsorption filter device 4, a suitable osmotic pressure is required, and when the pressure is too high, it will decrease. Adsorption effect: In order to ensure adsorption and purification and avoid excessive osmotic pressure, a waste gas storage device 3 is installed. After the VOC waste gas enters the elastic airbag 8 through the first exhaust pipe 2, when the amount of waste gas treated by the fiber carbon adsorption filter device 4 is less than the VOC waste gas After the amount of pumping, the gas pressure in the elastic airbag 8 will increase and expand accordingly. During the expansion process (the process of rel...

Abstract

The invention discloses a system for purifying VOC waste gas generared by Cigarette packaging and printing. The system comprises a VOC detector arranged in a workshop and a first gas discharging pipe communicated with a workshop waste gas discharging opening, and a waste gas storage device, a fiber carbon absorbing and filtering device, a black light lamp purifying device and a purifying and gas discharging pipe are sequentially arranged along a waste gas discharging and purifying route; the first gas discharging pipe is provided with a first gas discharging pump; the waste gas storage device comprises an elastic airbag with the size being stretched and contracted, the first gas discharging pipe is communicated with the elastic airbag, and the elastic airbag is communicated with the fiber carbon absorbing and filtering device. By means of the system, adsorption and filtering of the fiber carbon absorbing and filtering device and light irradiation and decomposition of the black light lamp purifying device can be utilized to purify the VOC waste gas discharged by a factory workshop, and atmospheric pollution is reduced.

Description

technical field [0001] The invention relates to a system for purifying VOC waste gas from cigarette packaging and printing. Background technique [0002] As we all know, cigarette packaging printing has the characteristics of full background color, many spot colors, simple picture and few continuous tone patterns. In terms of visual effects, there must be strong affinity or visual impact to stimulate consumers' desire to buy. The printing content of cigarette packs mainly includes solids, lines, dot patterns, ordinary text, discontinuous tone patterns, etc. In addition, anti-counterfeiting, embossing, bronzing, die-cutting, etc. are also commonly used processes in cigarette pack printing. In order to adapt to the content and characteristics of cigarette pack printing, cigarette packaging printing needs to adopt printing methods with high printing precision and strong color expression, such as gravure printing, flexographic printing, etc. In particular, gravure printing ha...
