Printing waste gas purification system and method for printed matter production

Abstract

The invention discloses a printing waste gas purification system and method for printed matter production, and relates to the technical field of printing waste gas purification. According to the printing waste gas purification system and method for printed matter production, a fixing box is included, a support is fixedly connected to the inner wall of the fixing box, a drawer is slidably connected to the upper side of the support, and an exhaust mechanism is arranged on the front side of the interior of the fixing box. According to the printing waste gas purification system and method for printed matter production, gas is fed through an inlet of the fixed box, air flow enters the fixed box initially to blow fan blades, the fan blades rotate to pull a rubber film upwards, and air flow on the upper side of the rubber film is extruded into a communicating cavity; and then the air flow is discharged through the communicating holes, so that the purpose of increasing the turbulence degree of the air flow in the fixed box is achieved, the contact time of the air flow and the activated carbon is prolonged, the activated carbon can be better adsorbed, and impurity deposition in the fixed box is reduced.

Description

technical field [0001] The invention relates to the technical field of printing waste gas purification, in particular to a printing waste gas purification system and method for printing production. Background technique [0002] In the process of the printing factory, there are three important links, the first is the imposition, then the proofing, and the last is the ink preset of the printing machine. In fact, the place where printing exhaust gas is produced is the ink, because the ink contains a part of the gas that is harmful to the human body. Different printing machines use different inks. Sometimes in order to speed up the drying speed of the ink, driers are added to the ink. , some harmful gases are also produced in these driers. The harmful gases produced in the ink and these additional components are not allowed to be discharged directly by the environmental protection department if they are not treated, so they need to be purified by installing exhaust gas treatmen...

AI Technical Summary

Problems solved by technology

The harmful gases produced in the ink and these additional components are not allowed to be discharged directly by the environmental protection department if they are not treated, so they need to be purified by installing exhaust gas treatment equipment. The exhaust gas treatment of printing plants uses activated carbon adsorption and desorption RCO catalytic combustion equipment for comparison Good, but the honeycomb-shaped activated carbon inside the general activated carbon adsorption bed is relatively densely placed, and there may be some dead spots to accumulate dirt under the action of wind force, and the speed of wind passing through the honeycomb-shaped activated carbon is relatively fast, which will make the dirt be adsorbed The process is short, so it will cause the accumulation of impurities in the internal exhaust gas, so a device is needed to reduce the deposition of pollutants inside the activated carbon adsorption bed
