Description

TECHNICAL FIELD

[0001] The utility model relates to floor processing environmental protection technical field, specifically, it is a floor uv roll coating line waste gas collecting device. BACKGROUND

[0002] Organic waste gas including VOCs (volatile organic compounds) is produced in the floor UV roll coating process, and these substances will pollute the environment if directly discharged without treatment. In the UV roll coating process, the generation of waste gas is closely related to the curing process. If the waste gas is not properly treated, it may affect the coating quality, resulting in product defects or rework. Harmful ingredients such as benzene, toluene, xylene, etc. in organic waste gas are harmful to human health, and may cause occupational health problems if not properly treated. Waste gas treatment of the floor UV roll coating line is of great significance to ensure production safety, improve product quality, comply with environmental regulations and achieve sustainable development.

[0003] When treating waste gas, the first step is to collect the waste gas generated during the floor roll coating production process. If the waste gas is collected separately on the entire roll coating production line, it is not conducive to the integration of the equipment. How to ensure the flexibility of the equipment while collecting waste gas from multiple processes on the floor production line is the key to improving waste gas collection efficiency and production efficiency.

And in the three different processes, the waste gas generated can be sucked into the collecting pipe under the action of the first telescopic exhaust mechanism, and then the waste gas generated in different processes on one production line can enter one collecting pipe for centralized treatment in the waste gas treatment device.
