Spraying waste gas mist purification system

Abstract

The invention relates to a spraying waste gas mist purification system which comprises a separation device and a fan. The separation device at least comprises a separation tower and a spiral separation filter element; the spiral separation filter element is arranged in the separation tower; the interior of the separation tower is divided into a spiral separation area and a flow guide area, which are communicated with each other, through the spiral separation filter element. The fan is arranged on the outer side of the separation tower and is used for sucking waste gas mist into the separation tower during working, and the waste gas mist in the separation tower is spirally separated and filtered through the spiral separation area and is discharged out of the separation tower through the flow guide area. The waste gas mist is separated and filtered under the spiral centrifugal acting force of the spiral separation area, and the separated and filtered gas is discharged from the flow guide area, so that the waste gas mist such as paint mist, solvent and dust generated when the spraying equipment works is effectively filtered and purified, and the spraying equipment can realize green spraying operation; the harm of the waste gas mist to the health of field personnel and the pollution to the air are reduced.

Description

technical field [0001] The invention relates to the field of purification of paint mist, solvent, dust and other waste gas mist, in particular to a spraying waste gas mist purification system. Background technique [0002] Spraying is the most commonly used coating method nowadays. It has the characteristics of high production efficiency and is suitable for industrial automation production. It is mainly used in furniture, hardware, military industry, ships and other fields. In the furniture processing industry, the painting process is the last process of furniture processing. During the spraying operation, there will be highly dispersed paint mist, volatilized solvents, and flying dust around the workpiece during the spraying process. These paint mist, Exhaust mist such as solvents and dust entering the workshop will affect the health of workers, and may catch fire and explode, seriously affecting the safety of spraying. If exhaust mist such as paint mist, solvents, and dust...

Problems solved by technology

In the furniture processing industry, the painting process is the last process of furniture processing. During the spraying operation, there will be highly dispersed paint mist, volatilized solvents, and flying dust around the workpiece during the spraying process. These paint mist, Exhaust mist such as solvents and dust entering the workshop will affect the health of workers, and may catch fire and explode, seriously affecting the safety of spraying. If exhaust mist such as paint mist, solvents, and dust is discharged outside, it will pollute the environment

[0003] Most of the existing spray purification uses wet or dry filtration for purification. For industries with low paint loss, this physical purification method is easy to operate and can meet the process requirements for standard discharge. However, for furniture spray paint For industries with high losses, physical purification methods often fail to achieve good purification effects
