1、 Spray paintingSpray exhaust gas treatmentProduct Introduction of Printing Factory

The ink, cleaning agents, and dampening solutions in printing factories usually contain a large amount of volatile organic compounds, mainly benzene, xylene, and other esters, which are harmful to the human body. Long term inhalation at certain concentrations can damage the nervous system, respiratory system, fertility, and even cause cancer. However, most printing factories' exhaust gas treatment equipment has simple processes and cannot effectively treat printing exhaust gas, becoming a decoration to deal with environmental protection bureaus.

Our company's independently developed washing and purification+activated carbon adsorption device first pretreats the exhaust gas with a water spray tower. The gas enters the water spray tower and is washed with water to remove smoke, dust, and acidic and alkaline exhaust gases. The remaining organic exhaust gas is then purified by an activated carbon adsorption device to avoid damage to the equipment caused by the exhaust gas.

2、 Principle of equipment for spray painting and exhaust gas treatment in printing plants:

1. Pre treat the exhaust gas using a spray tower. Install exhaust ducts and fans according to the actual situation, so that printing ink waste gas can be washed and purified through this equipment.

2. The exhaust gas after washing treatment is adsorbed by an activated carbon adsorption device. The function of the spray tower is to purify the exhaust gas and prevent particulate matter from blocking the activated carbon adsorption tower, thereby reducing the adsorption efficiency. The ink waste gas treated by the activated carbon adsorption device can be recycled and reused.

3、 Characteristics of equipment for spray painting and exhaust gas treatment in printing plants:

1. No need for dedicated management and daily maintenance, fully automated control operation design, simple operation.

2. The equipment has a compact structure, small footprint, simple and convenient maintenance, low operating costs, fully enclosed, and can be used both indoors and outdoors.

3. High efficiency, strong performance, and the ability to simultaneously treat multiple mixed organic waste gases.

Printing factory exhaust gas treatmentThe key is the configuration of the waste gas treatment process equipment. This method involves washing and pretreatment of organic waste gas, followed by adsorption treatment with activated carbon. The adsorbed ink is then collected and treated before being reused in production.

The spray tower, activated carbon adsorption device and other devices provided by our PP processing plant are all made of anti-corrosion materials such as PP board or fiberglass.
